Lentil Mushroom Stroganoff Ingredients
For the base
• Olive Oil – Ideal for sautéing onions but can be replaced with vegetable oil if preferred.
• Onion (1 medium) – Adds sweetness and depth; shallots can be a milder alternative.
• Salt (1-2 teaspoons total) – Enhances flavor; adjust based on personal taste.
• Butter (1 tablespoon) – Perfect for sautéing mushrooms; substitute with plant-based butter for a vegan option.
For the stroganoff
• Mushrooms (1.5 cups, sliced) – The star ingredient that adds umami; try cremini, shiitake, or portobello varieties.
• Garlic (2 cloves, minced) – Delivers aromatic flavors; garlic powder can work in a pinch.
• Dijon Mustard (2 teaspoons) – For that tangy depth; yellow mustard is a suitable replacement if needed.
• Black Pepper (¼ teaspoon) – Adds seasoning; tweak to your liking.
• Vegetable Stock (1.5 cups) – Moisture and flavor foundation; go for homemade or store-bought.
• Flour (2-3 tablespoons) – Thickens the rich sauce; gluten-free flour is great for gluten-free options.
For the finishing touch
• Lentils (1.5 cups, cooked) – Offers protein; canned lentils make preparation even easier.

Step‑by‑Step Instructions for Lentil Mushroom Stroganoff
Step 1: Sauté Onions
In a deep frying pan, heat 2 tablespoons of olive oil over medium heat. Once shimmering, add one finely chopped medium onion and 1 teaspoon of salt. Sauté for about 5–6 minutes, stirring occasionally, until the onions become golden brown and fragrant, creating a flavorful base for your Lentil Mushroom Stroganoff.
Step 2: Cook Mushrooms
In a separate skillet, melt 1 tablespoon of butter over medium heat. After the butter has melted, add 1.5 cups of sliced mushrooms with a pinch of salt. Cook for 5–6 minutes, stirring frequently, until the mushrooms are browned and have released their moisture, enhancing the umami flavor in the stroganoff.
Step 3: Combine & Season
Carefully transfer the sautéed mushrooms to the pan with the caramelized onions. Stir in 2 minced garlic cloves, 2 teaspoons of Dijon mustard, and ¼ teaspoon of black pepper. Pour in 1.5 cups of vegetable stock and bring the mixture to a simmer over medium heat for about 5 minutes to meld the flavors together beautifully.
Step 4: Prepare Slurry
In a small bowl, combine 2–3 tablespoons of flour with a splash of water or stock, whisking until smooth. This slurry will thicken your sauce, ensuring a creamy texture in your Lentil Mushroom Stroganoff. Set it aside while you continue to cook.
Step 5: Thicken Sauce
Add 1.5 cups of cooked lentils to the mushroom and onion mixture in the skillet, stirring well to combine. Gradually incorporate the prepared flour slurry, stirring continuously until the sauce thickens, which should take about 3–5 minutes. You’ll know it’s thickened when it coats the back of a spoon.
Step 6: Add Sour Cream
Reduce the heat to low and stir in ½ cup of sour cream, ensuring it blends seamlessly into the sauce. Allow it to heat through for a couple of minutes, adjusting seasoning as necessary with additional salt or pepper. This step will elevate the creaminess of your Lentil Mushroom Stroganoff.
Step 7: Serve
Garnish your completed Lentil Mushroom Stroganoff with freshly chopped parsley for a vibrant touch. Serve it hot over a bed of mashed potatoes, pasta, or rice. The aroma and flavors will surely invite everyone to the table for a cozy, comforting meal.
