How to Make French Lentil and Mushroom Soup Recipe
Step 1: Sauté the Aromatics
Start by warming olive oil in a large pot over medium heat. Toss in your diced onion, carrots, and celery, then sauté for about 5 to 7 minutes. This softens the vegetables, allowing their natural sweetness and fragrance to unfold and build a flavorful foundation.
Step 2: Add Garlic
Next, stir in the minced garlic and let it cook for an extra minute. This brief step lets the garlic release its lovely aroma without overpowering the dish or turning bitter, setting the stage for the rich flavors to come.
Step 3: Cook the Mushrooms
Add your sliced mushrooms and cook for another 5 to 6 minutes. Watch them closely as they let go of their moisture and start to brown—this caramelization deepens their umami richness, lending wonderful complexity to the soup.
Step 4: Combine Lentils and Broth
Once your vegetables and mushrooms are perfectly sautéed, stir in the rinsed French green lentils, then pour in the vegetable broth. Sprinkle in dried thyme and tuck in the bay leaf. Turn up the heat and bring everything to a lively boil. This step signals that your soup is filling up with flavor and ready to simmer into perfection.
Step 5: Simmer the Soup
Lower the heat to a gentle simmer and cover the pot. Allow the soup to cook for 30 to 35 minutes, giving the lentils enough time to soften while still holding their shape. This simmering is where all the flavors meld beautifully, creating a hearty and comforting bowl.
Step 6: Finish with Vinegar and Seasoning
Before serving, remove the bay leaf and stir in the balsamic vinegar. This little splash adds a subtle brightness that balances the earthiness of the lentils and mushrooms perfectly. Season with salt and black pepper to your taste, ensuring each spoonful is deliciously well-rounded.
Step 7: Serve and Garnish
Ladle your French Lentil and Mushroom Soup Recipe into warm bowls, then sprinkle chopped fresh parsley on top. This final touch adds a refreshing burst of color and a gentle herbaceous note that truly makes the dish shine.

Garnishes
While fresh parsley is a classic and vibrant garnish, don’t hesitate to get creative with toppings. A dollop of crème fraîche or a sprinkle of shaved Parmesan can add an extra layer of indulgence, or for an earthy crunch, consider toasted walnuts or crispy sage leaves.
Side Dishes
This soup pairs beautifully with a rustic crusty bread or a warm baguette, perfect for dipping and soaking up all that rich broth. A simple mixed greens salad with a light vinaigrette also complements the soup’s heartiness, keeping the meal balanced and fresh.
Creative Ways to Present
If you want to impress guests, serve this French Lentil and Mushroom Soup Recipe in small cups or bowls as an elegant starter. Garnish each serving with a sprig of fresh thyme or a drizzle of good-quality olive oil for a restaurant-worthy touch that’s sure to wow.
Make Ahead and Storage
Storing Leftovers
This soup keeps wonderfully in the refrigerator for up to 4 days. Store it in an airtight container to preserve all those lovely flavors and prevent it from absorbing other fridge aromas. When you’re ready for a cozy meal, simply reheat and enjoy.
Freezing
If you want to make this soup well in advance or batch cook, it freezes beautifully. Transfer cooled soup into freezer-safe containers or bags, leaving some room for expansion. It will keep for up to 3 months, making it an easy, nourishing option on busy days.
Reheating
Reheat your soup gently on the stovetop over medium heat, stirring occasionally to heat it evenly. You can add a splash of vegetable broth or water if it feels too thick. Avoid overheating, which might cause the lentils to become mushy; instead, warm it just until steaming hot and enjoy.
FAQs
Can I use any type of lentils for this recipe?
While the French green lentils (lentilles du Puy) are preferred because they hold their shape and have a slightly peppery flavor, you can substitute with brown lentils if needed. Just note the texture and cooking time might vary slightly.
What if I don’t have balsamic vinegar?
The balsamic vinegar adds a subtle sweetness and acidity that brightens the soup, but if you’re out, a splash of red wine vinegar or lemon juice can provide a similar effect. Add it gradually and taste as you go.
Can I make this soup vegan?
Absolutely. This entire French Lentil and Mushroom Soup Recipe is naturally vegan as long as you use vegetable broth. It’s a fantastic plant-based option that’s hearty and satisfying.
How thick or thin should the soup be?
The soup has a slightly thick texture thanks to the lentils, but it should still be brothy enough to be soupy. If it becomes too thick during cooking or reheating, simply add a bit more vegetable broth or water to achieve your preferred consistency.
Can I add other vegetables to this soup?
Definitely! Feel free to experiment by adding diced potatoes, tomatoes, or leafy greens like spinach near the end of cooking. Just keep in mind that altering the vegetables can slightly change the cooking time and flavor balance.

This French Lentil and Mushroom Soup Recipe is one of those dishes that feels like a warm hug in a bowl. It’s nourishing, flavorful, and surprisingly simple to make with pantry-friendly ingredients.
