Rich Lentil Bolognese with Sun-Dried Tomatoes

This Rich Lentil Bolognese with Sun-Dried Tomatoes is a hearty, plant-based take on the classic Italian sauce that’s ready in just 40 minutes. Packed with tender green lentils, tangy sun-dried tomatoes and aromatic herbs, this vegan bolognese delivers deep, satisfying flavor perfect for tossing with pasta, layering in lasagna or spooning over creamy polenta.

What Makes This Vegetarian Bolognese Special

This healthy vegetarian dinner is incredibly hearty and meaty in texture without any actual meat. Green lentils hold their shape beautifully when simmered, creating that satisfying bite you want in a bolognese sauce.

The sun-dried tomatoes are the secret weapon here. They add intense, concentrated tomato flavor with a hint of sweetness and tang that regular tomatoes just can’t match. Combined with crushed tomatoes, tomato paste and a splash of red wine, you get layers of rich, complex tomato flavor that tastes like it’s been simmering for hours.

This sauce is perfect for meal prep and freezing. Make a big batch on Sunday and you’ll have quick dinners ready all week, or freeze portions for up to 3 months. It reheats beautifully and actually tastes even better the next day as the flavors meld together.

Nutritionally, green lentils are powerhouses. They’re loaded with plant-based protein to keep you full and satisfied, tons of fiber that’s great for digestion (especially good to eat at lunch to keep you energized all afternoon), and iron for healthy blood and energy levels. Plus they’re rich in folate and antioxidants.

Using a high-quality Dutch oven really makes a difference here. The heavy bottom prevents burning while the even heat distribution helps all those flavors develop perfectly. It’s an investment that’ll transform how you make sauces, soups and braises.

Ingredients

You’ll need green lentils, sun-dried tomatoes (the oil-packed kind work best for flavor), crushed tomatoes, aromatics and Italian herbs. Simple pantry staples that create magic together.

For the Bolognese:

1½ cups green or brown lentils, rinsed
½ cup sun-dried tomatoes in oil, drained and chopped
1 can (28 oz/800g) crushed tomatoes (or 3½ cups crushed fresh tomatoes)
3 tablespoons tomato paste
1 large onion, finely diced
3 cloves garlic, minced
2 medium carrots, finely diced
2 celery stalks, finely diced
½ cup red wine (or vegetable broth)
2 cups vegetable broth
2 tablespoons olive oil
2 teaspoons dried oregano
1 teaspoon dried basil
1 bay leaf
½ teaspoon red pepper flakes (optional)
Salt and black pepper to taste
Fresh basil for garnish

How to Make This Easy Lentil Recipe

Heat the olive oil in a large pot or Dutch oven over medium heat.
Add the diced onion, carrots and celery. Cook for 7-8 minutes, stirring occasionally, until the vegetables are softened and the onion is translucent.
Add the minced garlic and cook for another minute until fragrant.
Stir in the tomato paste and cook for 2 minutes, stirring constantly. This deepens the tomato flavor.
Add the chopped sun-dried tomatoes and stir to combine with the vegetables.
Pour in the red wine to deglaze the pot, scraping up any browned bits from the bottom with a wooden spoon. Let it simmer for 2-3 minutes until slightly reduced.
Add the rinsed lentils, crushed tomatoes, vegetable broth, oregano, basil, bay leaf and red pepper flakes if using.
Stir everything together and bring to a boil over high heat.
Once boiling, reduce heat to low, cover with a lid slightly ajar and simmer for 30-35 minutes, stirring occasionally. The lentils should be tender but still holding their shape, and the sauce should be thick and rich.
Remove the bay leaf. Taste and season generously with salt and black pepper.
If the sauce is too thick, add a splash of vegetable broth or pasta cooking water. If it’s too thin, simmer uncovered for 5-10 more minutes.
Serve hot over your favorite pasta, garnished with fresh basil and vegan parmesan if desired.

Substitutions and Variations

No sun-dried tomatoes? Use an extra 2 tablespoons of tomato paste plus 1 teaspoon of balsamic vinegar for that concentrated tangy sweetness.

Make it even heartier by adding ½ cup finely chopped mushrooms with the other vegetables for extra umami depth and meaty texture.

Add fresh herbs at the end like torn basil, chopped parsley or fresh thyme for brightness.

Use red lentils if that’s what you have, but reduce cooking time to 15-20 minutes as they break down faster and create a smoother, less chunky sauce.

Skip the wine and use all vegetable broth, but add 1 tablespoon balsamic vinegar for acidity.

Boost the protein by stirring in 1 cup of cooked white beans during the last 5 minutes of cooking.

What to Serve With This Vegan Pasta Sauce

Classic spaghetti or penne is the obvious choice, and for good reason. The sauce clings beautifully to pasta ridges and the combination is pure comfort food that everyone loves.

Creamy polenta makes this feel like an upscale Italian dinner. Pour the bolognese over soft, buttery polenta and top with fresh herbs for a cozy meal that’s naturally gluten-free.

Garlic bread is essential for soaking up every last bit of this rich sauce. Toast thick slices brushed with olive oil and rubbed with garlic for the perfect side.

Zucchini noodles turn this into a lighter, low-carb option that’s still incredibly satisfying. The meaty lentil sauce more than makes up for the lighter base.
