Ingredients Method

Ingredients

  

• Olive oil (2–3 tablespoons)
• Yellow onion (1 medium, finely chopped)
• Carrots (2 small, finely diced)
• Celery stalks (2, finely diced)
• Garlic (4 cloves, minced)
• Tomato paste (2 tablespoons)
• Crushed tomatoes (1 can, 28 ounces) or passata
• Brown or green lentils (1 cup, uncooked; rinse and pick over)
• Vegetable broth or water (3–4 cups)
• Dry red wine (1/2 cup, optional but recommended)
• Dried oregano (1 teaspoon)
• Bay leaf (1)
• Crushed red pepper flakes (a pinch, optional)
• Balsamic vinegar (1–2 teaspoons)
• Soy sauce or tamari (1 teaspoon for umami, optional)
• Salt and black pepper (to taste)
• Pasta (12–16 ounces; spaghetti, rigatoni, or fettuccine)
• Fresh basil or parsley (a small handful, chopped)
• Parmesan or a vegan hard cheese (for serving, optional)

Method

 

1. Prep the base: Heat olive oil in a large pot over medium heat. Add onion, carrots, and celery with a pinch of salt. Cook, stirring, until soft and lightly golden, about 8–10 minutes.
2. Build flavor: Stir in garlic and cook 1 minute until fragrant. Add tomato paste and cook 2–3 minutes, stirring, until it darkens slightly and coats the vegetables.
3. Deglaze: Pour in red wine (if using) and scrape up any browned bits. Let it reduce by about half, 1–2 minutes.
4. Add tomatoes and lentils: Stir in crushed tomatoes, lentils, oregano, bay leaf, and red pepper flakes if using. Add 3 cups of broth. Bring to a simmer.
5. Simmer gently: Reduce heat to low, cover partially, and cook 25–35 minutes, stirring occasionally. Add more broth as needed to keep it saucy. Lentils should be tender but not mushy.
6. Season and enrich: Remove the bay leaf. Stir in balsamic and soy sauce. Taste and season with salt and pepper. If the sauce is too tangy, add a pinch of sugar or a knob of butter/olive oil.
7. Cook the pasta: Meanwhile, boil pasta in salted water until just shy of al dente. Reserve 1 cup of pasta water.
8. Marry pasta and sauce: Add drained pasta to the pot with the lentil Bolognese. Toss over low heat, adding splashes of pasta water to loosen and help the sauce cling. Cook 1–2 minutes until glossy and well coated.
9. Finish and serve: Stir in chopped herbs. Serve with grated Parmesan or a vegan alternative, a drizzle of olive oil, and black pepper.

Why This Recipe Works

This sauce balances hearty texture with bright flavor. Brown or green lentils hold their shape and provide a meat-like bite, while tomato paste builds richness without needing hours on the stove. A classic mix of onion, carrot, and celery adds sweetness and depth, and a splash of red wine gives the sauce a savory backbone.

Simmering with bay leaf, oregano, and a touch of balsamic rounds out the sauce and softens the acidity of the tomatoes.

Finishing the pasta in the sauce helps the flavors cling to each noodle. It’s simple, reliable, and consistently delicious.

Instructions

1. Prep the base: Heat olive oil in a large pot over medium heat. Add onion, carrots, and celery with a pinch of salt.

   Cook, stirring, until soft and lightly golden, about 8–10 minutes.

2. Build flavor: Stir in garlic and cook 1 minute until fragrant. Add tomato paste and cook 2–3 minutes, stirring, until it darkens slightly and coats the vegetables.
3. Deglaze: Pour in red wine (if using) and scrape up any browned bits. Let it reduce by about half, 1–2 minutes.
4. Add tomatoes and lentils: Stir in crushed tomatoes, lentils, oregano, bay leaf, and red pepper flakes if using.

   Add 3 cups of broth. Bring to a simmer.

5. Simmer gently: Reduce heat to low, cover partially, and cook 25–35 minutes, stirring occasionally. Add more broth as needed to keep it saucy.

   Lentils should be tender but not mushy.

6. Season and enrich: Remove the bay leaf. Stir in balsamic and soy sauce. Taste and season with salt and pepper.

   If the sauce is too tangy, add a pinch of sugar or a knob of butter/olive oil.

   Cook 1–2 minutes until glossy and well coated.

9. Finish and serve: Stir in chopped herbs. Serve with grated Parmesan or a vegan alternative, a drizzle of olive oil, and black pepper.

Storage Instructions

Cool the sauce completely before storing. Refrigerate in an airtight container for up to 4 days. Freeze the sauce (without pasta) for up to 3 months; thaw overnight in the fridge and reheat gently, adding a splash of water or broth to loosen.

If you have leftovers with pasta already mixed in, store for up to 2 days. Reheat with a bit of water to bring back the sauce’s silky texture.

Fresh herbs and cheese are best added right before serving.

Why This is Good for You

Lentils are a powerhouse of plant-based protein and fiber, helping you feel full and steadying energy. They bring iron, folate, and minerals without saturated fat. Olive oil and tomato bring heart-friendly nutrients, including lycopene from cooked tomatoes.

Compared to a meat-based Bolognese, this version is lighter while still satisfying.

It’s a smart way to cut back on meat without sacrificing comfort or flavor.

Pitfalls to Watch Out For

• Under-seasoning: Lentils are mild. Salt in layers—vegetables, simmering sauce, and final adjustment.
• Overcooking the lentils: Aim for tender with a bit of bite. Check at 25 minutes and add liquid as needed.
• Skipping the tomato paste step: Let it caramelize.

  That’s your shortcut to depth and “slow-cooked” flavor.

• Sauce too thick or too thin: Adjust with broth or pasta water. You want a loose, glossy coat on the pasta.
• Forgetting acidity and umami: A touch of balsamic and soy sauce transforms the flavor. Don’t skip both.

Variations You Can Try

• Mushroom boost: Add 8 ounces finely chopped cremini or portobello with the vegetables for extra umami.
• Creamy finish: Stir in a splash of cream, oat cream, or cashew cream at the end for a silky texture.
• Herb swap: Replace oregano with thyme or rosemary, or finish with fresh oregano leaves for a brighter profile.
• Spicy arrabbiata twist: Increase red pepper flakes and add a pinch of smoked paprika.
• Gluten-free: Use gluten-free pasta and tamari instead of soy sauce.
• Whole-grain upgrade: Choose whole-wheat pasta for extra fiber and a nutty bite.
• Slow-cooker option: Sauté aromatics and tomato paste on the stove, then transfer to a slow cooker with the rest.

  Cook on low 4–5 hours, adding liquid if needed.

FAQ

Can I use canned lentils?

Yes. Rinse and drain 2 cans of lentils. Reduce the broth to about 1 cup and simmer the sauce for 10–15 minutes to meld flavors.

Add lentils for the last 5–8 minutes so they don’t turn mushy.

What pasta shape works best?

Rigatoni, spaghetti, and fettuccine are great. Short shapes with ridges hold chunky sauce well, while long strands give that classic tangle. Use what you like and cook it just shy of al dente before finishing in the sauce.

Do I have to use wine?

No.

Skip the wine and add an extra splash of broth plus 1 teaspoon balsamic or 1 teaspoon lemon juice to balance acidity. The sauce will still be rich and flavorful.

How can I make it even richer?

Add a pat of butter or a drizzle of good olive oil at the end, or stir in a spoonful of miso paste for deep savory notes. A sprinkle of Parmesan rind simmered in the sauce also adds body—remove before serving.

Can I make it ahead?

Absolutely.

The sauce tastes even better the next day. Reheat gently, thinning with water or broth as needed. Cook fresh pasta when you’re ready to serve.

What if my sauce is too acidic?

Add a small pinch of sugar or a splash of cream to soften the edges.

Simmer a few extra minutes and adjust salt to keep the flavors balanced.

Which lentils should I avoid?

Skip red or yellow lentils here. They break down quickly and are better for soups or dal. Choose brown or green for structure and chew.
