How to Make Lentil Mushroom Stroganoff: A Hearty Vegetarian Delight Recipe
Step 1: Sauté Onions
Start by heating olive oil in a deep pan over medium heat, then add the finely chopped onion along with half the salt. Cook gently for about 5 to 6 minutes until the onions turn golden brown and develop a naturally sweet, rich flavor. This step sets the savory foundation for your stroganoff, so don’t rush it!
Step 2: Cook Mushrooms
In a separate pan, melt the butter over medium-high heat and add the mushrooms with the remaining salt. Sauté for 5 to 6 minutes, stirring occasionally, allowing the mushrooms to brown evenly and release their wonderful earthy juices. This caramelization step is key for that deep mushroom flavor.
Step 3: Combine & Season
Transfer the browned mushrooms to the pan with the onions. Stir in the chopped garlic, Dijon mustard, and black pepper, letting the aromas mingle for a minute or two before pouring in the vegetable stock. Bring the mixture to a gentle simmer and let it cook for about 5 minutes to marry all the flavors and slightly reduce the liquid.
Step 4: Prepare Slurry
While the sauce simmers, whisk together the flour with 2 to 3 tablespoons of water or vegetable stock in a small bowl, stirring until completely smooth. This slurry will be the magic thickener that transforms your sauce into that perfect creamy texture we all expect from stroganoff.
Step 5: Thicken Sauce
Now, stir the cooked lentils into the mushroom and onion mixture. Slowly pour in the slurry, stirring constantly to avoid lumps and to help the sauce thicken evenly. Cook for a few minutes until the sauce reaches a silky, luscious consistency that clings invitingly to every ingredient.
Step 6: Add Sour Cream
Reduce the heat to low and gently fold in the sour cream until it is fully incorporated into the sauce. Check your seasoning and adjust if needed. The sour cream adds that signature tang and creaminess that makes this dish so comforting.
Step 7: Serve
Garnish with freshly chopped parsley and serve your Lentil Mushroom Stroganoff: A Hearty Vegetarian Delight Recipe piping hot over mashed potatoes, egg noodles, or a bed of rice for a complete and satisfying meal that’s bursting with flavor.

Make Ahead and Storage
Storing Leftovers
Leftovers keep wonderfully in an airtight container in the fridge for up to 3 days. The flavors actually deepen overnight, making it a great dish for meal prep or unexpected guests.
Freezing
This stroganoff freezes well. Portion it into freezer-safe containers or bags and it can keep for up to 3 months. Just be sure to leave some space at the top for expansion and thaw it overnight in the fridge before reheating.
Reheating
Reheat gently on the stovetop over low heat, stirring occasionally. You might want to add a splash of water or stock to loosen the sauce, as it thickens when chilled. Avoid high heat to keep the sour cream from curdling and retain the silky sauce texture.
FAQs
