Ingredients

• For the Creamy Mushroom Filling
• 1 oz / 28g dried wild mushrooms
• 3 Tbs / 42g butter, divided
• 2 Tbs / 20g minced onion
• 1 cup / 240g sour cream
• 8 oz / 225g large fresh mushrooms, sliced
• 1 pinch dried thyme
• ½ tsp / 2.5g salt, or to taste
• Freshly ground black pepper to taste
• ½ tsp dried dill or 1 tsp fresh dill
• For the Omelets
• 8 large eggs
• ¼ cup / 60ml milk or heavy cream
• Salt and freshly ground black pepper to taste
• Butter for frying
• For Garnish
• Chopped fresh parsley

Instructions

1. Rehydrate the dried mushrooms by soaking them in 2 cups / 475ml of hot water for at least 2 hours. Once soft, lift them out, gently squeeze, and coarsely chop. Carefully strain the soaking liquid through a cheesecloth-lined sieve to remove grit and reserve the liquid.
2. Melt 2 Tbs / 28g of butter in a skillet over medium heat. Sauté the minced onion until it begins to soften. Add the chopped rehydrated mushrooms, the sour cream, and 1 cup / 240ml of the reserved mushroom liquid. Reduce heat and simmer, stirring occasionally, until the sauce thickens and mushrooms are tender.
3. In a separate small skillet, melt the remaining 1 Tbs / 14g of butter. Sauté the sliced fresh mushrooms for 5-6 minutes until golden. Sprinkle with thyme, toss briefly, and then add them to the sour cream mixture.
4. Season the sauce with salt, pepper, and dill. Continue simmering until the sauce is thick and no longer runny. Keep warm.
5. To make the omelets, whisk the eggs, milk or cream, and a pinch of salt and pepper in a bowl until smooth.
6. Heat a non-stick pan with a little butter over medium heat. Pour in enough egg mixture for one omelet (enough for one of four small, or one of two large omelets). Cook until the edges are set but the center is still slightly moist.
7. Spoon a portion of the mushroom filling onto one half of the omelet, then fold the other half over. Slide onto a plate, sprinkle with fresh parsley, and serve immediately. Repeat for the remaining omelets.

Pro Tips

• Don’t skip straining the mushroom soaking liquid. It’s packed with umami flavor but can contain grit, so passing it through a coffee filter or cheesecloth is essential for a smooth sauce.
• For the fluffiest omelets, use room temperature eggs and whisk just until the yolks and whites are combined. A hot, well-buttered non-stick pan is your best friend for a perfect fold.
• If your sauce seems too thin, simply let it simmer a bit longer to reduce. If it becomes too thick, stir in a splash of cream or more mushroom liquid to reach the perfect consistency.

FAQ

Q: Is this mushroom omelet a good source of vegetarian protein
A: Absolutely. This recipe is an excellent source of high-quality vegetarian protein, with approximately 20g per serving. The protein comes primarily from the eight large eggs, making it a very filling and satisfying meal perfect for a nutritious start to your day or a hearty breakfast-for-dinner.

Q: Can I make this creamy mushroom omelet vegan
A: Yes, you can adapt this recipe to be fully vegan. Use a plant-based butter, a high-quality vegan sour cream, and a rich plant-based cream like cashew or oat cream. For the omelet itself, use a commercial liquid vegan egg substitute or a chickpea flour batter. These substitutions will create a delicious and decadent plant-based version.

Q: What if I can’t find dried wild mushrooms
A: No problem. If you can’t find dried wild mushrooms, you can use an additional 4-5 oz of fresh mushrooms instead. To achieve a similar deep, umami flavor, use a mix of flavorful mushrooms like cremini, shiitake, or portobello. You can also add a teaspoon of mushroom powder or a splash of soy sauce to the sauce to enhance its savory depth.

Q: How do I store and reheat leftovers
A: For the best results, store the creamy mushroom filling separately from the omelets in an airtight container in the refrigerator for up to 3 days. Reheat the sauce gently in a saucepan, adding a splash of milk or cream if it has thickened too much. It’s always best to cook the omelets fresh, but you can reheat a fully assembled omelet in a non-stick skillet over low heat until warmed through.
