Rinse and Soak the Lentils: Start by rinsing the French lentils under cold water to remove any debris. Then, soak them in water for about 30 minutes. This helps them cook more evenly and reduces the cooking time.
Prepare the Vegetables: Dice the onion and carrots, and finely chop the garlic. Set them aside, ready to add their magic to the dish.
Sauté the Aromatics: In a large saucepan, heat 1 tablespoon of olive oil over medium heat. Add the diced onions and cook until they turn translucent and slightly golden. Toss in the garlic and stir for a minute until fragrant.
Sauté Mushrooms: Add the remaining olive oil and sliced mushrooms to the saucepan. Sauté until the mushrooms are tender and start to brown. Season with salt and pepper to taste.
Add Lentils and Vegetables: Drain the soaked lentils and add them to the saucepan. Stir in the diced carrots, thyme, and bay leaves.
Pour in the Broth: Pour in the vegetable broth, ensuring it covers the lentils and vegetables. Bring the mixture to a gentle boil.
Simmer and Cook: Reduce the heat to a simmer and let the lentils cook uncovered for about 25-30 minutes, or until they are tender but still hold their shape. Stir occasionally and add more broth if needed.
Adjust Seasoning: Taste the lentils and adjust the seasoning with salt and pepper to your liking.
Serve and Enjoy: Remove the bay leaves before serving. Plate the French Lentils With Mushrooms, garnish with a sprig of fresh thyme if desired.
