This oyster mushroom toast layers crispy oyster mushrooms over toasted sourdough and creamy ricotta whipped with white miso, Parmesan, and lemon zest. It's savory, rich, and packed with umami, with fresh chives and a little lemon to brighten it up.
The inspiration for this recipe came from one of my favorite bites on a trip through France. At La Mère Germaine in Châteauneuf-du-Pape, I had an incredible mushroom toast made with brocciu cheese and chestnuts. My version isn't intended to exactly recreate that dish, but I loved the combination of earthy mushrooms, creamy cheese, and crisp bread so much that I knew I wanted to make my own take on a mushroom toast when I got home.
I originally developed this mushroom toast as an appetizer for a friend's birthday dinner. Here's the full menu from that birthday dinner if you're looking for some ideas of how to serve this toast!
I developed all three of these dishes for the dinner and didn't originally intend on posting the recipes, but this toast was such a standout that I changed my mind. A lot of the prep can be done in advance, making it great for dinner parties.
📚 Why This Recipe Works
High heat gives oyster mushrooms their best texture
The most important part of this oyster mushroom recipe is getting a good sear. A hot, uncrowded skillet lets the mushrooms develop deeply browned, crispy edges while retaining their meatier centers.
Neutral oil handles the initial high-heat cooking, while butter is added toward the end for flavor and richness, after the mushrooms have browned and most of their released moisture has cooked away.
Miso and Parmesan transform the ricotta
White miso and Parmesan turn mild ricotta into a savory, umami-rich base that can stand up to the deeply browned mushrooms. The white miso is mild enough that it adds a little funk but doesn't dominate the ricotta, while Parmesan contributes another layer of umami and salt.
Extra-virgin olive oil adds richness and helps create a fluffy spread, while lemon zest and lemon juice provide just enough brightness without making the ricotta acidic.
Every layer adds a different texture
The sourdough is toasted until crisp on the exterior but still a little chewy inside, the ricotta is soft and creamy, and the oyster mushrooms have meaty centers and crisp, browned edges. That contrast is a big part of what makes such a simple combination feel elevated.
This recipe yields extra ricotta spread
The ricotta mixture starts with one full 15-ounce container, which makes a little more than you'll need for 4 toasts. This saves the step of measuring the ricotta and having just a little bit left behind. You can apply the spread generously when you make the toasts and still have some left over. Save it for an easy ricotta toast the next day!
♥️ Why We Love This Recipe
- Ready in about 25 minutes. It feels like an elevated restaurant appetizer without becoming an elaborate cooking project.
- Fantastic texture. Crisp sourdough, fluffy ricotta, and deeply seared mushrooms give you something different in every layer.
- Easy to prep for entertaining. Make the ricotta ahead so you only need to toast the bread and sear the mushrooms shortly before serving.
- Bonus ricotta for later. The recipe intentionally makes extra miso-Parmesan ricotta, and the leftovers are great spread on toast the next day.
🍷 Beverage Pairings
The right beverage can make a great meal even better. Drawing on my Introductory Sommelier certification through the Court of Master Sommeliers, I'm adding complementary pairing suggestions for each recipe.
Wine
GSM Blend
I may be a little biased given that the dish that inspired this recipe came from Châteauneuf-du-Pape, but a Grenache-Syrah-Mourvèdre (GSM) blend is a great pairing here. The savory, earthy character works especially well with the deeply browned mushrooms and Parmesan, while the fruit and spice complement the richness of the toast. For an especially fitting pairing, look for a GSM-style blend from the Southern Rhône. There are also some great GSM blends coming out of Paso Robles, California.
Brut Champagne
Dry sparkling wine gives you a very different kind of pairing. The acidity and bubbles cut through the ricotta and butter, while Champagne has enough savory complexity to stand up to the miso, Parmesan, and browned mushrooms.
Sake
Junmai
A savory, relatively full-bodied junmai is a natural partner for the miso and mushrooms. Its umami-friendly character works especially well with the Parmesan and crispy edges of the oyster mushrooms.
Beer
Saison
A dry saison brings enough brightness to refresh your palate after the creamy ricotta, while its earthy and lightly spicy character can complement the mushrooms.
Cocktails
French 75
Gin, lemon, and sparkling wine make a French 75 bright and refreshing alongside the rich mushroom toast.
Non-Alcoholic
Dry Non-Alcoholic Sparkling Wine
A dry sparkling wine alternative can play a similar role to Champagne: acidity and bubbles help balance the creamy ricotta and buttery mushrooms. Look for one that's genuinely dry rather than noticeably sweet!
📋 Ingredient Notes

Oyster Mushrooms
I used pink oyster mushrooms when developing this recipe, but other clustered oyster mushroom varieties work well too. Pearl and blue oyster mushrooms are great options and are often easier to find, while golden oyster mushrooms are another fun choice when available.
Pink oyster mushrooms are especially striking when raw, but don't worry when their vibrant color fades during cooking. Getting a deep golden-brown sear and crisp edges is much more important than trying to preserve their pink color.
Rather than chopping the mushrooms uniformly, tear apart the clusters and leave the individual mushrooms and larger pieces fairly substantial. The irregular pieces create a nice combination of crisp edges and meatier centers.
King oyster mushrooms are a little different from the clustered varieties used here. Their large, thick stems need to be sliced and handled differently, so they aren't my first choice for this particular mushroom toast.
Note, pink oyster mushrooms can go bad quickly. I typically source mine from local farmers markets and try to use the mushrooms within 1-2 days of purchasing. I usually place them in a paper bag, with a paper towel included to absorb extra moisture, then store in the fridge.
Whole-Milk Ricotta
Whole-milk ricotta creates the creamy base for the toast. Whip it with the other ingredients until fully combined and fluffy for a smooth spread that's easy to pile generously onto the sourdough.
The recipe intentionally uses a full 15-ounce container even though you won't need all of the finished spread for four toasts. This avoids leaving part of a container behind and gives you extra miso-Parmesan ricotta for later.
White Miso
White miso gives the ricotta a savory, funky, umami-rich flavor without overwhelming the mushrooms. Its mildness works especially well with creamy ricotta. I don't recommend substituting a stronger miso, such as red miso, at the same quantity. If you do use a stronger variety, start with less and adjust to taste.
Parmesan
Finely grated Parmesan reinforces the savory flavor and adds saltiness to the ricotta. If available, I recommend using a real, aged Parmigiano-Reggiano for the best flavor. Grate it very finely so it incorporates evenly into the spread. I use the smallest holes on my box grater.
Extra-Virgin Olive Oil
Extra-virgin olive oil adds richness to the ricotta and helps create a smooth, fluffy spread. I prefer a good-quality extra-virgin olive oil from Tuscany for its flavor. You'll also need a little extra for brushing the sourdough before toasting.
Lemon Zest & Juice
A small amount of finely grated lemon zest and juice adds brightness without making the ricotta overtly lemony. The zest adds some lemon flavor while the juice cuts the richness of the ricotta slightly, making it feel less heavy.
Sourdough Bread
Use large slices of sourdough sturdy enough to hold a generous layer of ricotta and mushrooms. I usually pick up a freshly baked sourdough loaf from the farmers market, but commercially made sourdough works well too. If you're buying it at the grocery store, look for a round, bakery-style loaf rather than sandwich bread-shaped sourdough so you can use large, substantial slices. Toast the bread deeply enough to create a crisp exterior while retaining some chew in the center.
Neutral Oil & Butter
Neutral oil is used for the initial high-heat mushroom sear, while butter is added toward the end for flavor. Waiting to add the butter until the mushrooms are browned gives you buttery flavor without relying on it for the hottest part of the cooking, where it may burn.
Chives, Sea salt, & Black Pepper
Finely sliced chives add a fresh note and a little color to the finished toast. Freshly ground black pepper and sea salt season the ricotta and the finished dish.
🥘 Instructions
Please see the recipe card at the bottom of the page for the full, detailed instructions.
Step 1: Whip the ricotta, white miso, Parmesan, olive oil, lemon zest, lemon juice, and black pepper together until fully combined and fluffy.
Step 2: Trim away the tough base of the oyster mushroom clusters, then tear the mushrooms into individual mushrooms and substantial bite-sized pieces.
Step 3: Brush both sides of the sourdough lightly with olive oil and toast or grill until deeply golden and crisp on the outside with some chew remaining in the center.
Step 4: Heat a skillet until properly hot, add the neutral oil, then arrange the oyster mushrooms in an uncrowded single layer. Leave them mostly undisturbed for 2–3 minutes to develop a deep sear.
Step 5: Flip or toss the mushrooms and continue cooking until browned with crisp edges and most of their released moisture has cooked away. Add the butter and toss briefly to coat, then season lightly with salt and black pepper.
Step 6: Spread each warm toast generously with the miso-Parmesan ricotta, pile the hot oyster mushrooms on top, and finish with sliced chives and freshly ground black pepper and sea salt. Serve immediately.
👩🏼🍳 Key Tips
- Get the skillet properly hot. A well-preheated pan helps the oyster mushrooms brown quickly rather than slowly releasing moisture and steaming.
- Give the mushrooms room. Arrange them in a single, uncrowded layer so moisture can escape and the mushrooms can make good contact with the skillet. If you double this recipe, make sure you use two pans to cook the mushrooms or work in two batches.
- Don't stir constantly. Leave the first side mostly undisturbed for 2–3 minutes. This is key to developing deeply browned, crisp edges.
- Add the butter at the end. Wait until the mushrooms are browned and most of their released moisture has cooked away, then add the butter for flavor.
- Season lightly. The miso-Parmesan ricotta is already quite savory, so the mushrooms don't need heavy seasoning.
- Serve immediately. Assemble while the mushrooms are hot and the sourdough is crisp for the best texture.
♻️ Variations
Try Different Oyster Mushroom Varieties
Pink oyster mushrooms are what I used when developing this recipe, but you can make the toast with other clustered oyster mushroom varieties, including pearl, blue, or golden oysters.
King oyster mushrooms are more distinct, with thick, substantial stems rather than delicate clusters. While you could certainly make mushroom toast with them, they would need to be sliced and cooked differently, so I recommend a clustered oyster variety for this version.
🫙 Storage & Leftovers
Refrigerator
The miso-Parmesan ricotta can be prepared ahead and stored covered in the refrigerator. Take it out about 20–30 minutes before serving and give it a good stir so it isn't fridge-cold and overly firm when you spread it over the toast.
The recipe intentionally makes extra ricotta. I used the leftovers for more toast the next day without the mushrooms, and it was great on its own.
Make Ahead
The ricotta is the best component to prepare in advance. You can also clean and tear the mushrooms ahead of time, but wait to cook them until shortly before serving.
Toast the bread, sear the mushrooms, and assemble everything close to serving time. Storing the assembled toast would sacrifice the texture.
Freezer
I don't recommend freezing this mushroom toast. This recipe is particularly dependent on its contrasting textures and is best enjoyed fresh.
❓ FAQ
Oyster mushrooms have a mild, savory flavor and a tender, somewhat meaty texture. Their relatively delicate flavor makes them versatile enough to pair with assertive ingredients like miso and Parmesan while still retaining their own character.
Yes. This recipe was developed using pink oyster mushrooms, but pearl, blue, and golden oyster mushrooms are also good options. Look for clustered oyster varieties if you want the closest substitute.
Not really. Pink oyster mushrooms lose much of their vibrant color during cooking. Don't sacrifice browning to try to preserve the color. The deep sear and crisp edges are much more important to the finished dish.
Start with a properly heated skillet and arrange the mushrooms in a single, uncrowded layer. Leave the first side mostly undisturbed for a few minutes so it has time to develop a deep golden-brown sear.
Continue cooking until most of the moisture released by the mushrooms has evaporated before adding the butter. This helps you achieve browned edges rather than wet or steamed mushrooms.
Clean oyster mushrooms as needed with a damp cloth to remove any growing medium or debris. Avoid soaking them in water, and make sure they're relatively dry before they go into the skillet so excess moisture doesn't interfere with browning.
You can prepare the miso-Parmesan ricotta ahead of time, but wait to toast the bread, sear the mushrooms, and assemble everything until shortly before serving. The contrast between hot mushrooms, creamy ricotta, and crisp bread is an important part of the recipe.
🍽️ What to Serve it With
These oyster mushroom toasts work particularly well as a first course for a dinner party or special meal. One large toast per person makes a generous appetizer, so they pair best with a relatively simple main course and fresh sides.
- A simple green salad with a bright vinaigrette
- Roast chicken with seasonal vegetables
- Steak or beef tenderloin with a simple vegetable side
- Beef and root vegetable stew
Because the toast itself is rich and savory, I like the rest of the meal to have some freshness rather than pairing it with several other creamy or cheese-heavy dishes.
🥗 Serving Size
This recipe makes four large appetizer toasts, with one large slice of sourdough per person. I served one whole toast to each guest as a first course, and it was a nice portion for a generous appetizer.
The 5 ounces of oyster mushrooms are divided among all four toasts. You'll have some miso-Parmesan ricotta left over because the recipe intentionally uses a full 15-ounce container rather than scaling the spread down to exactly what is needed for four servings.

Oyster Mushroom Toast with Whipped Ricotta
Ingredients
Miso-Parmesan Ricotta
- 15 oz whole-milk ricotta one small standard container
- 2 tablespoon white miso paste
- ⅓ cup finely grated Parmesan
- 3 tablespoon extra-virgin olive oil
- 1 teaspoon finely grated lemon zest optional
- 1 tablespoon lemon juice optional
- freshly ground black pepper to taste
Mushrooms & Toast
- 5 to 6 oz pink oyster mushrooms or similar, such as pearl, blue, or golden oyster mushrooms
- 1 tablespoon neutral cooking oil I use avocado oil
- 1 tablespoon butter
- Salt to taste
- freshly ground black pepper to taste
- 4 large slices sourdough bread
- extra-virgin olive oil for brushing the toast
- fresh chives finely sliced, for finishing
Instructions
- Make the miso-Parmesan ricotta: Add the ricotta, white miso, Parmesan, olive oil, lemon zest, lemon juice, and black pepper to a bowl and whip until fully combined and fluffy. Refrigerate until ready to use.Note: This recipe makes more ricotta than you'll need for 4 toasts. There's enough for about 6 if you'd like to make a larger batch.
- Prepare the mushrooms: Clean oyster mushrooms as needed with a damp cloth to remove any growing medium or debris. Avoid soaking them in water, and make sure they're relatively dry before they go into the skillet. Trim away any tough bases and stems from the oyster mushrooms. Tear the mushrooms by hand into bite-sized pieces.
- Toast the sourdough: Lightly brush both sides of the sourdough with olive oil. For the best results, toast the bread on a griddle or skillet over medium heat for a few minutes per side, until deeply golden and crisp on the outside. Alternatively, toast the bread in a toaster oven until golden and crisp.
- Sear the mushrooms: Heat a large skillet over medium-high to high heat. Add the neutral oil and wait for it to become hot and shimmery. Once hot, add the mushrooms and toss until they are evenly coated, then arrange the mushrooms in a single, uncrowded layer. Cook mostly undisturbed for 2–3 minutes to develop a deep golden-brown sear.
- Finish the mushrooms: Flip or toss the mushrooms and cook for another 2–3 minutes, until well browned with crisp edges. Reduce the heat to low and add the butter. Toss for 30–60 seconds, then remove from heat.
- Assemble: Spread each warm slice of sourdough generously with the miso-Parmesan ricotta. Top with the hot oyster mushrooms and finish with sliced chives. Optionally, add some fresh cracked black pepper and sea salt. Serve immediately.
