Ingredients
• For the Soufflé
• 2 ounces / 57 g dried black mushrooms
• 5½ tablespoons / 80 g butter, divided
• 4 tablespoons / 30 g all-purpose flour
• 1 cup / 240 ml hot milk
• ½ cup / 120 g sour cream
• ½ teaspoon salt, or to taste
• ¼ teaspoon black pepper, or to taste
• 1 pinch cayenne pepper
• 6 large egg yolks, at room temperature
• 2 tablespoons chopped fresh dill
• 1 small onion, finely chopped
• ¼ cup / 40 g chopped shallots
• 8 large egg whites, at room temperature
• 1 pinch cream of tartar
• 1 to 2 tablespoons / 10-20 g grated Parmesan cheese
• For Serving
• Hollandaise Sauce or Spicy Mousseline Sauce
Instructions
1. First, prepare your baking vessel. Generously butter a 2-quart soufflé dish and coat the inside evenly with the grated Parmesan cheese. For an extra-tall rise, create a collar by buttering a long piece of parchment paper or aluminum foil and tying it securely around the outside of the dish, extending at least 2 inches above the rim. Set aside.
2. Preheat your oven to 400°F / 200°C.
3. Place the dried mushrooms in a bowl and cover with 1½ cups of boiling water. Let them soak for at least 2 hours, or overnight, until fully rehydrated. Drain the mushrooms, reserving the flavorful soaking liquid. Carefully rinse the mushrooms to remove any grit, then chop them coarsely.
4. Strain the reserved mushroom liquid through a fine-mesh sieve or cheesecloth to filter out any remaining grit. You will need 1 cup of this liquid.
5. In a saucepan over medium-low heat, melt 3½ tablespoons of the butter. Whisk in the flour to form a paste (a roux) and cook for 2 minutes, stirring constantly. In a separate bowl, whisk the hot milk and sour cream together, then gradually pour this mixture into the roux, whisking continuously until the sauce is very thick and smooth.
6. Remove the sauce from the heat. Season with salt, pepper, and a pinch of cayenne. Beat in the egg yolks one at a time, ensuring each is fully incorporated before adding the next. Stir in the chopped fresh dill and set the sauce base aside.
7. In a medium skillet, melt the remaining 2 tablespoons of butter over medium heat. Add the chopped onion and shallots and sauté until soft and golden. Add the chopped mushrooms, season with a little more salt and pepper, and cook for 2-3 minutes. Pour in 1 cup of the reserved mushroom liquid. Continue to cook, stirring occasionally, until all the liquid has been absorbed.
8. Stir the hot mushroom mixture directly into the sauce base, mixing until everything is well combined.
9. In a large, impeccably clean bowl, beat the egg whites with a pinch of salt and the cream of tartar using an electric mixer. Start on low speed and gradually increase to high, beating until they form stiff, glossy peaks.
10. Gently lighten the mushroom base by stirring in about a quarter of the beaten egg whites. Then, pour the lightened base over the remaining egg whites. Using a large spatula, carefully fold the mixture together until just combined, being careful not to deflate the whites.
11. Pour the soufflé mixture into your prepared dish. Place it on the middle rack of the preheated oven and immediately reduce the temperature to 375°F / 190°C.
12. Bake for 35 to 40 minutes, or until the soufflé is puffed, beautifully golden-brown, and a skewer inserted into the center comes out mostly clean. Serve immediately with a drizzle of Hollandaise or Spicy Mousseline Sauce.

Pro Tips
• for a Perfect Soufflé
• Ensure your egg whites and yolks are at room temperature. Room-temperature whites will whip up to a much greater volume, giving your soufflé a lighter, airier texture.
• The bowl and beaters used for whipping egg whites must be completely clean and free of any fat or grease. Even a tiny speck of egg yolk can prevent the whites from reaching stiff peaks.
• Master the folding technique. Use a large spatula to cut down through the middle of the mixture, scrape along the bottom of the bowl, and bring it up and over. This gently combines the while preserving the precious air in the egg whites.
• Resist the urge to open the oven door while the soufflé is baking! The sudden change in temperature can cause your magnificent creation to collapse prematurely.
FAQ
Q: Is this mushroom soufflé a good source of vegetarian protein
A: Yes, this is an excellent source of vegetarian protein. Each serving contains approximately 15 grams of protein, primarily from the eight large eggs and the Parmesan and sour cream used in the recipe.
Q: Can I make this mushroom soufflé dairy-free or vegan
A: Unfortunately, this specific recipe relies heavily on dairy (butter, milk, sour cream, cheese) and eggs for its structure and flavor. Substituting these ingredients would require a completely different formulation. We recommend searching for a dedicated vegan soufflé recipe that uses plant-based alternatives for leavening and richness.
Q: How can I make this vegetarian soufflé gluten-free
A: To make this soufflé gluten-free, you can substitute the all-purpose flour in the roux with a 1-to-1 gluten-free all-purpose flour blend. The rest of the ingredients are naturally gluten-free, but always double-check your labels for any hidden gluten.
Q: What other vegetarian-friendly mushrooms can I use in this soufflé
A: While dried black mushrooms provide a deep, earthy flavor, you can certainly use other varieties. Try a mix of fresh, sautéed mushrooms like cremini, shiitake, or chanterelles. Sauté them until they release their moisture before adding them to the base to avoid a watery soufflé.
Q: Can I store and reheat leftover soufflé
A: A soufflé is best served immediately as it will deflate upon cooling. While you can store leftovers in an airtight container in the refrigerator for up to 2 days, it will not have the same light, airy texture. You can gently reheat individual portions in the oven or microwave until warmed through.
