How to Make Lentil Mushroom Stroganoff: A Hearty Vegetarian Delight
Step 1: Sauté Onions
Begin by heating olive oil in a deep pan over medium heat. Add the finely chopped onion along with half the salt, and cook gently for 5 to 6 minutes until the onions turn golden brown and soft. This slow cooking unlocks their natural sweetness, forming a flavorful foundation for the stroganoff.
Step 2: Cook Mushrooms
While the onions are softening, melt butter in a separate pan on medium-high heat. Add the sliced mushrooms and the remaining salt, sautéing for another 5 to 6 minutes until they are beautifully browned. The mushrooms develop a rich umami flavor and a slightly crisp texture that elevate the dish’s heartiness.
Step 3: Combine and Season
Once the mushrooms are ready, add them to the onions in the deep pan. Stir in the chopped garlic, Dijon mustard, and freshly ground black pepper. Pour in the vegetable stock, then let the mixture simmer gently for 5 minutes to marry all those wonderful flavors into a cohesive sauce.
Step 4: Prepare Slurry
In a small bowl, whisk together the flour and water or stock until completely smooth. This slurry will be key to thickening the sauce into that classic creamy consistency you’re craving for your Lentil Mushroom Stroganoff: A Hearty Vegetarian Delight.
Step 5: Thicken Sauce
Stir in the cooked brown lentils to the pan, allowing their hearty texture to soak up the sauce. Then, gradually add the slurry while stirring continuously to avoid lumps. Keep the sauce on medium heat until it thickens and coats the back of a spoon, giving you that perfect, velvety finish.
Step 6: Add Sour Cream
Reduce the heat to low and gently fold in the sour cream until fully blended, creating a luscious, creamy sauce. Taste and adjust seasoning if necessary, ensuring that your Lentil Mushroom Stroganoff: A Hearty Vegetarian Delight is bursting with balanced flavor and ready to serve.
Step 7: Serve
Top the stroganoff with fresh chopped parsley just before serving to add a fresh pop of color and brightness. This dish tastes incredible when served over mashed potatoes, pasta, or rice—whatever you prefer as your comfort-carb base.
