Ingredients You’ll Need (Nothing Fancy, Promise)

This soup leans into simple pantry staples, layered thoughtfully for maximum flavor.

Vegetable Mixture

2 tbsp olive oil
1 medium yellow onion, diced
2 carrots, diced
2 celery stalks, diced
3 garlic cloves, minced

Mushroom Mixture

8 oz cremini or button mushrooms, sliced

The Rest of the Good Stuff

1½ cups French green lentils (lentilles du Puy), rinsed
6 cups vegetable broth
1 tsp dried thyme
1 bay leaf
1 tbsp balsamic vinegar
Salt and black pepper, to taste
2 tbsp fresh parsley, chopped (for garnish)

How to Make This French Lentil and Mushroom Soup Recipe

This process is calm, steady, and forgiving—just how weeknight cooking should be.

Step 1: Build the Flavor Base

Grab a large pot and heat the olive oil over medium heat. Add the onion, carrots, and celery. Sauté for about 5–7 minutes, stirring occasionally, until everything softens and smells like the start of something good.

Step 2: Wake Up the Garlic

Add the minced garlic and cook for 1 minute. Keep it moving—garlic likes attention and burns if ignored (don’t we all?).

Step 3: Mushroom Magic

Add the sliced mushrooms. Cook for 5–6 minutes, letting them release their moisture and begin to brown. This step adds that deep, savory backbone that makes this French Lentil and Mushroom Soup Recipe feel rich and comforting.

Step 4: Simmer Time

Stir in the lentils, vegetable broth, thyme, and bay leaf. Bring everything to a boil, then reduce the heat to a gentle simmer.

Cover and let it cook for 30–35 minutes, until the lentils are tender but still hold their shape.

Step 5: Finish Like a Pro

Remove the bay leaf. Stir in the balsamic vinegar—it adds just the right hint of brightness. Season with salt and black pepper to taste.

Ladle into bowls and finish with a sprinkle of fresh parsley.

Cooking Tips from My Kitchen to Yours

If your soup looks thick: Add a splash of broth or water. Lentils love to soak things up.
Want extra depth? A splash of dry white wine added with the mushrooms takes this soup to the next level.
Short on time? Dice your veggies the night before. Your future self will thank you.
Soup tastes “meh”? A pinch more salt or an extra teaspoon of balsamic usually fixes it.

And don’t worry if the soup looks a little rustic. This isn’t a runway model—it’s comfort food.
