This hearty lentil Bolognese is a soul-warming, plant-based rendition of the timeless Italian classic. Packed with rich, savory flavors and nourishing ingredients, it brings comfort and depth to every bite. Earthy lentils, robust aromatics, and a medley of vegetables simmer into a luscious, slow-cooked sauce that satisfies like traditional Bolognese, without relying on meat. It’s the kind of dish that fills the kitchen with aroma and the plate with wholesome goodness.
Ingredients Breakdown
At the heart of this recipe lies a classic mirepoix—finely diced onion, celery, and carrots—sautéed until golden and aromatic. These foundational vegetables build the base of the sauce, offering sweetness, subtle bitterness, and mellow depth. Garlic joins the mix, bringing sharpness and pungency that elevates every layer of flavor. Tomato paste adds intensity and umami, while a generous splash of red wine, though optional, deglazes the pan and imparts richness and sophistication. Dried Italian herbs or fresh sprigs of oregano or thyme infuse warmth and complexity throughout the simmering sauce.
The star ingredients—black caviar lentils and ground walnuts—give the sauce a hearty, meat-like texture. The lentils absorb the savory broth and tomato juices, while the ground nuts offer subtle nuttiness and a satisfying bite. The liquid components—vegetable stock, canned tomatoes with their juices, and a finishing splash of balsamic vinegar—tie everything together into a velvety, full-bodied sauce. Optional chili flakes provide a flicker of heat, while salt and pepper sharpen and balance the flavor. Seasoning is flexible, allowing space for creative interpretation.
Step-by-Step Cooking Method
Start by heating olive oil in a heavy-bottomed pot or Dutch oven. Add the onions and sauté until translucent, releasing their natural sweetness. Layer in the celery, carrots, and garlic, letting the aromatics soften slowly. Add the herbs, salt, pepper, and chili flakes, stirring as the base melds into a fragrant vegetable medley.
Once softened, add the tomato paste and let it brown slightly in the pan—this caramelization enhances depth and lends a robust character to the sauce. Deglaze the pan with a splash of red wine, scraping up any flavorful bits. The wine’s acidity cuts through the richness and elevates the profile of the sauce. Stir in the diced tomatoes with their juices, letting them simmer just enough to start breaking down.
Introduce the lentils, broth, and ground walnuts. Bring everything to a gentle boil, then reduce the heat and cover. Let the sauce simmer until the lentils are tender, absorbing flavor and releasing their creamy texture. Once tender, uncover and allow excess moisture to reduce, thickening the sauce into a hearty consistency. Finish by stirring in a splash of balsamic vinegar for brightness and complexity. Taste and adjust seasoning before serving.
Recipe Tips & Frequently Asked Questions
Choosing the best type of lentils for quicker cooking and better texture:
Opt for small, firm lentils like black caviar or French green lentils. Avoid red lentils, which break down too quickly and lose texture.
How to avoid a watery sauce—achieving the right thickness:
Simmer uncovered after the lentils are cooked to allow excess liquid to reduce naturally. Stir often for an evenly thick consistency.
Tips for toasting and grinding walnuts for optimal flavor:
Toast the walnuts in a dry skillet before grinding. This enhances their aroma and deepens their nutty flavor in the sauce.
Substitution ideas for herbs and aromatics:
Use rosemary, basil, or marjoram in place of oregano or thyme. Shallots can replace onions for a slightly sweeter note.
Can this be made ahead of time and stored?
Yes, this sauce stores beautifully. Refrigerate for up to 5 days or freeze for up to 3 months.
What other lentils can I use if I don’t have caviar lentils?
French green lentils or brown lentils are good alternatives; avoid mushy lentils like red or yellow.
Can I skip the wine or replace it with something else?
Yes, substitute with a splash of vegetable broth and a teaspoon of balsamic vinegar for acidity.
How can I make this recipe nut-free?
Replace walnuts with hemp seeds or sunflower seed meal for similar texture.
What’s the best way to reheat leftovers without drying it out?
Add a splash of broth or water when reheating on the stovetop to loosen the sauce without compromising flavor.
What to Serve With This Recipe

Finish with toppings like grated pecorino, fresh basil leaves, or a drizzle of olive oil to bring everything together.
Flavor Variations and Enhancements
Add sautéed mushrooms or roasted zucchini to introduce an earthy, savory element. Turn it into a baked dish by layering it with pasta, béchamel, and cheese. For a richer flavor, blend in roasted red peppers or sun-dried tomatoes. If you’re feeling adventurous, swap the walnuts for ground hazelnuts or cashews for a slightly different twist.

Ingredients
2 tablespoons olive oil
1 large onion, finely diced (approximately 2 to 2 ½ cups)
1 ½ cups carrots, small diced
1 ½ cups diced celery
4–6 cloves garlic, roughly chopped
1 ½ teaspoons salt, or to taste
½ teaspoon freshly ground black pepper
¼ teaspoon red chili flakes (optional)
1 tablespoon fresh oregano or thyme (or substitute with 2 teaspoons dried Italian seasoning)
⅓ cup tomato paste
¼ cup red wine (optional, a generous splash)
1 ½ cups diced tomatoes with juices (or one 14-ounce can diced or crushed tomatoes)
1 ¼ cups black caviar lentils or any small, quick-cooking lentils
3 ½ cups vegetable broth or stock (or use water and 2–3 bouillon cubes)
¾ cup ground toasted walnuts (or substitute with hemp hearts or ground pecans)
2 teaspoons balsamic vinegar
Instructions
Warm the olive oil in a large Dutch oven or heavy-bottomed pot over medium-high heat. Add the diced onion and sauté for 2 to 3 minutes, stirring often, until the aroma becomes fragrant and the edges begin to soften.
Reduce the heat to medium and stir in the diced carrots, celery, chopped garlic, salt, pepper, chili flakes, and your choice of fresh or dried herbs. Let everything cook together for 7 to 8 minutes, stirring occasionally, allowing the vegetables to soften and the flavors to deepen.
Add the tomato paste to the mixture and let it cook for a couple of minutes, allowing it to slightly caramelize against the pan—this enhances its rich, umami flavor. Pour in the red wine, if using, scraping up any flavorful bits that may have stuck to the bottom of the pan.
Stir in the diced tomatoes with their juices and simmer the mixture for a few more minutes to blend the flavors.
Next, add the lentils, vegetable stock (or water with bouillon), and the ground walnuts or their substitutes. Stir well, bring the mixture to a gentle boil, then reduce the heat to low. Cover the pot tightly and simmer for 20 to 25 minutes, or until the lentils are tender. Larger varieties of lentils may require additional time to soften fully.
Once the lentils are cooked, remove the lid and continue simmering uncovered until most of the excess liquid has evaporated and the sauce has thickened.
Finish by stirring in the balsamic vinegar, then taste and adjust seasoning as needed—consider an extra pinch of salt, a dash more vinegar for brightness, or an extra sprinkle of chili flakes for heat. The sauce should be slightly more seasoned than usual, especially if pairing it with pasta.
Serve this hearty lentil Bolognese generously tossed with your favorite pasta or ladled over creamy polenta for a rustic, comforting meal. Garnish with grated pecorino cheese or a flavorful vegan alternative, such as a cheesy sprinkle blend.

Notes
- Hemp Seeds: Use only shelled hemp hearts (soft inner seeds). Avoid whole hemp seeds, as they will create a gritty texture.
- Broth: If your vegetable broth tastes mild or the Bolognese lacks depth, enhance the flavor with a small splash of soy sauce, miso paste mixed with a bit of water, or vegetable bouillon paste.
- Lentils: For quicker cooking, choose small lentils like French green lentils or split red lentils. Brown lentils require more time and may soften too much.
- Storage: This dish can be prepared in advance and stored in the refrigerator for up to 4 days.
