Background

The traditional Bolognese sauce, or ragù alla bolognese, hails from Bologna, Italy. Traditionally made with minced meat, tomatoes, and wine, it’s known for its slow-cooked richness and hearty depth. Over the years, modern cooks have adapted it into countless variations — and the plant-based version has become one of the most loved transformations.

This vegan twist swaps meat for lentils — a nutrient powerhouse packed with protein, fiber, and minerals — and adds layers of flavor through aromatic vegetables, tomato paste, and Italian herbs. The zucchini noodles replace pasta with a fresh, low-carb alternative that still carries the sauce beautifully. This combination creates a dish that’s light yet filling, indulgent yet guilt-free — a perfect example of how plant-based cooking can be both wholesome and deeply satisfying.

Ingredients & Equipment

For the Lentil Bolognese

  • 1 cup (200 g) dry brown or green lentils, rinsed
  • 1 tablespoon olive oil
  • 2 medium carrots, diced
  • 1 medium onion, finely chopped
  • 2 celery stalks, diced
  • 3 cloves garlic, minced
  • 2 tablespoons tomato paste
  • 1 can (400 g / 14 oz) crushed tomatoes
  • 2 cups (480 ml) vegetable broth
  • 1 teaspoon dried oregano
  • 1 teaspoon dried basil
  • ½ teaspoon thyme
  • Salt and black pepper to taste
  • Optional: ½ teaspoon smoked paprika for depth

For the Zucchini Noodles

  • 3 large zucchinis, spiralized into noodles
  • 1 teaspoon olive oil
  • Pinch of salt

Equipment

  • Large skillet or saucepan
  • Spiralizer or julienne peeler
  • Wooden spoon
  • Fine mesh strainer

Pro Tip: For an extra thick and rich sauce, cook the lentils uncovered in the final stages to let the sauce reduce naturally.

Step-by-Step Instructions

Step 1: Cook the Lentils

Rinse the lentils under cold water, then place them in a pot with 3 cups (720 ml) of water. Bring to a boil, reduce heat, and simmer for 20–25 minutes until tender but not mushy. Drain and set aside.

Step 2: Prepare the Base

In a large skillet or saucepan, heat olive oil over medium heat. Add the chopped onion, carrot, and celery, and sauté for about 6–8 minutes until the vegetables are soft and fragrant. Stir in the minced garlic and cook for another 30 seconds until aromatic.

Step 3: Build the Sauce

Add tomato paste and cook for 2 minutes to caramelize slightly — this deepens the flavor. Then stir in the crushed tomatoes, vegetable broth, oregano, basil, thyme, and paprika. Mix well and bring to a gentle simmer.

Step 4: Add the Lentils

Add the cooked lentils to the sauce and stir until fully coated. Reduce the heat to low and let the mixture simmer for 15–20 minutes, stirring occasionally. The sauce will thicken as it reduces and the flavors meld together beautifully.

Step 5: Prepare the Zucchini Noodles

While the sauce simmers, spiralize your zucchini into long noodles. In a large skillet, heat a teaspoon of olive oil over medium heat. Sauté the zoodles for 2–3 minutes — just until slightly softened but still firm. Overcooking can make them watery, so keep them al dente.

Step 6: Combine and Serve

Pile the zucchini noodles into bowls and spoon generous amounts of the lentil Bolognese on top. Finish with a drizzle of olive oil, a sprinkle of cracked pepper, or a few fresh basil leaves for garnish.

Expert Tips & Troubleshooting

  • Avoid watery sauce: Simmer uncovered near the end to allow excess liquid to evaporate.
  • Zucchini noodle tip: Salt zoodles lightly and let them rest for 5 minutes before cooking to draw out extra moisture.
  • Boost umami: Add a splash of soy sauce or a teaspoon of nutritional yeast for deeper flavor.
  • Meal prep ready: Store sauce and zoodles separately to prevent sogginess.

Variations & Customizations

  • Spicy Kick: Add red chili flakes or a dash of hot sauce for heat.
  • Creamy Style: Stir in a tablespoon of cashew cream or coconut milk for a velvety texture.
  • Hearty Veggie Mix: Add mushrooms or chopped spinach for extra depth and nutrients.
  • Whole-Grain Option: Serve the lentil Bolognese over whole wheat or chickpea pasta instead of zoodles.
  • Mediterranean Twist: Add olives and roasted red peppers for a bold, briny flavor.

Serving & Presentation Ideas

Serve the Plant-Based Lentil Bolognese in wide, shallow bowls for an inviting presentation. Garnish with fresh basil, a drizzle of olive oil, and a sprinkle of vegan parmesan or toasted breadcrumbs.

Pair this dish with a crisp green salad or garlic-roasted vegetables for a complete meal. It’s also delicious served alongside crusty whole-grain bread to soak up every bit of sauce.

Storage & Make-Ahead Tips

The lentil sauce keeps well in an airtight container in the refrigerator for up to 4 days. In fact, the flavor deepens with time, making it perfect for meal prep.

To freeze, let the sauce cool completely, then store it in freezer-safe containers for up to 3 months. Thaw overnight in the fridge and reheat gently on the stove with a splash of broth. Prepare fresh zucchini noodles before serving for best texture.
