- Leeks (1 1/2 cups, finely diced): Offer a mild onion flavor that deepens the savory profile.
- Red bell pepper (1 cup, finely diced): Adds brightness and a hint of sweetness.
- Mushrooms (1 pound, finely diced): Their umami richness is what makes this Bolognese truly hearty.
- Garlic (3 cloves, minced): Infuses the sauce with warmth and a punch of flavor.
- Fresh thyme (1 teaspoon) and oregano (1 teaspoon): Essential herbs that build the Italian flavor backbone.
- Tomato paste (1 tablespoon): Concentrates tomato flavor for depth and color.
- Kosher salt and freshly ground black pepper: Enhances all other flavors perfectly.

How to Make Lentil and Mushroom Bolognese Recipe
Step 1: Sauté the Base Vegetables
Start by warming the olive oil in a heavy-bottomed pot over medium-high heat. Toss in the finely diced celery, carrots, leeks, and red bell pepper. Cook them gently, stirring frequently for about 8 to 10 minutes until they soften and begin to caramelize. This step is crucial as it builds the deep, natural sweetness and layers of flavor that form the heart of the sauce. If the veggies begin sticking, don’t hesitate to add a little more olive oil – it will only boost richness.
Step 2: Cook the Mushrooms
Next, add in the mushrooms and continue cooking for another 8 minutes or so, stirring often. The mushrooms will release moisture at first, but as you keep cooking, most of this evaporates and the mushrooms caramelize, bringing a meaty texture and that coveted umami goodness to the dish. This is truly where the magic begins, transforming familiar vegetables into something extraordinary.
Step 3: Add Garlic, Herbs, and Tomato Paste
Stir in the minced garlic along with fresh thyme, oregano, and tomato paste. Sauté for about a minute until fragrant – this brief step intensifies their flavors without letting the garlic burn. Then season with kosher salt, freshly ground black pepper, and if you’re feeling adventurous, a pinch of crushed red pepper flakes for subtle heat that lifts the overall flavor.
Step 4: Deglaze and Build the Sauce
Pour in the vegetable broth to deglaze the pot, scraping up any caramelized bits stuck to the bottom—they’re pure flavor gold. Continue cooking for 1 to 2 minutes so the liquid reduces slightly, concentrating the taste and allowing all ingredients to meld together perfectly.
Step 5: Combine Lentils, Tomatoes, and Simmer
Now it’s time to add the crushed tomatoes and dry lentils to the pot. Bring everything to a gentle boil, then reduce the heat to low. Cover the pot and let it simmer for 25 minutes, stirring occasionally to prevent sticking. This slow simmer allows the lentils to cook through and soak up all those wonderful flavors while thickening the sauce beautifully.
Step 6: Final Simmer and Seasoning
After the lentils are tender, remove the lid and cook uncovered for an additional 5 minutes to thicken the sauce further. If the texture feels too thick or dry, simply add a bit more broth to adjust. Taste and tweak the seasoning with extra salt and pepper as needed before stirring in fresh parsley or basil right at the end for an aromatic, fresh burst.
