Step‑by‑Step Instructions for Lentil Mushroom Stroganoff
Step 1: Sauté Onions
Heat a drizzle of olive oil in a deep frying pan over medium heat. Add the chopped onion and a pinch of salt, stirring occasionally for about 5-6 minutes until the onions become golden and fragrant. This forms the aromatic base for your Lentil Mushroom Stroganoff.
Step 2: Cook Mushrooms
In a separate pan, melt a tablespoon of butter over medium-high heat. Once melted, add the sliced mushrooms along with a sprinkle of salt. Sauté for about 5-6 minutes until the mushrooms are browned and tender, releasing their rich, savory aroma that complements the stroganoff.
Step 3: Combine & Season
Carefully transfer the cooked mushrooms to the pan with the sautéed onions. Stir in the minced garlic, Dijon mustard, and black pepper, cooking for another minute until the garlic is fragrant. Pour in the vegetable stock, bringing the mixture to a gentle simmer for about 5 minutes to meld the flavors.
Step 4: Prepare Slurry
In a small bowl, whisk together the flour with 2-3 tablespoons of water or stock until smooth. This slurry will help thicken the sauce, ensuring a creamy texture for your Lentil Mushroom Stroganoff. Set it aside while the sauce simmers.
Step 5: Thicken Sauce
Stir the cooked lentils into the mushroom mixture, ensuring they are well combined. Slowly pour in the flour slurry while stirring continuously, watching as the sauce thickens and coats the ingredients beautifully. This step transforms the dish into a hearty comfort food.
Step 6: Add Sour Cream
Reduce the heat to low and gently stir in the sour cream until fully blended, creating a rich and creamy finish for your stroganoff. Taste and adjust the seasoning as necessary, bringing a perfect balance of flavors to your Lentil Mushroom Stroganoff.
