Ingredients:

• 8–9 oz spaghetti
• ½ cup red lentils (split skin)
• 1 tsp olive oil
• ½ small onion, finely diced
• 4 cloves garlic, minced
• 4 oz mushrooms, finely chopped
• ¼ cup shredded carrots
• ¼ tsp dried thyme
• ¾ tsp dried oregano
• 1 tsp dried basil
• 1–2 tsp tomato paste (optional)
• 16–18 oz marinara or crushed tomatoes
• ¼ cup red wine or vegetable broth + 2 tsp balsamic vinegar
• Salt, black pepper, red pepper flakes, to taste
• Fresh basil for garnish

Ingredient Notes and Substitutions

Red lentils are the star here, and honestly, they’re the only lentils I’d recommend for this recipe. Green or brown lentils just won’t give you that perfect texture breakdown. If you can’t find split red lentils, regular red lentils work fine, they just might take a few extra minutes to soften.

The mushrooms add that earthy, umami depth that makes this sauce so satisfying. Any variety works, but baby bellas or cremini mushrooms are my go-to choices. Don’t skip the carrots either, they add a subtle sweetness that balances all those savory flavors.

For the liquid component, red wine creates incredible depth, but vegetable broth with balsamic vinegar works beautifully too. The acid from either option helps brighten the whole dish and keeps it from tasting flat. If you’re using wine, don’t stress about using the expensive stuff, a basic cooking wine does the job perfectly.

How to Make this Hearty Lentil Bolognese Spaghetti

Let all those vegetables get nice and softened, which usually takes about 5-7 minutes. You want the onions to look translucent and the mushrooms to release their moisture. Don’t rush this part, it’s building the flavor foundation for everything that comes next.

Next comes the herb party. Add your ¼ tsp dried thyme**, ¾ tsp **dried oregano**, 1 tsp dried basil, and if you’re using it, 1-2 tsp tomato paste**. Stir everything around for about a minute until it smells absolutely incredible. The tomato paste, if you’re using it, will deepen in color and add this rich, concentrated tomato flavor that makes everything taste more expensive than it actually is.

Time for the liquid components. Pour in your ¼ cup red wine** or vegetable broth plus 2 tsp balsamic vinegar**. Let this cook and reduce down, which takes maybe 3-4 minutes. You want most of the liquid to cook off, concentrating all those flavors.

Here’s where things get really good. Add your ½ cup red lentils and 16-18 oz marinara or crushed tomatoes. Give everything a good stir and let it come to a gentle simmer. Now you wait, and this is probably the hardest part because it smells so good already.

Let this whole beautiful mess simmer for 15-20 minutes until those lentils are completely tender and the sauce has thickened up nicely. The lentils will basically dissolve into the sauce, creating this hearty, meaty texture that’s honestly kind of mind-blowing. You’ll know it’s ready when you can run a spoon through it and it doesn’t immediately fill back in.

Season everything with salt, black pepper, and red pepper flakes to taste. Start conservatively here because you can always add more, but you can’t take it back. Serve this gorgeous sauce over your cooked spaghetti and top with some fresh basil** if you’ve got it hanging around.

The whole thing comes together in about 30 minutes, most of which is just letting it simmer while you do other things. Like maybe clean up the kitchen so you don’t have to face that disaster later.

Hearty Lentil Bolognese Spaghetti Substitutions and Variations

Since this recipe basically acts like edible LEGO blocks, you can swap out almost every ingredient and still end up with something delicious.

Can’t find red lentils? Green or brown work perfectly, though they’ll take longer to break down. I prefer using cremini mushrooms for their deeper flavor, but button mushrooms work fine too.

Want more vegetables? Diced bell peppers, celery, or zucchini blend beautifully into this sauce.

You can also substitute the spaghetti with penne, rigatoni, or even zucchini noodles if you’re avoiding carbs.

For protein variations, add crumbled tofu or plant-based ground meat during the sautéing step.

What to Serve with Hearty Lentil Bolognese Spaghetti

While this lentil bolognese absolutely shines on its own, the right side dishes can transform your dinner from satisfying to downright memorable.

I’m partial to a crisp Caesar salad—those crunchy romaine leaves provide the perfect textural contrast to the rich, saucy pasta.

Garlic bread feels almost mandatory, doesn’t it? The buttery, toasted edges soak up every last bit of that lentil goodness.

For something lighter, I’ll reach for roasted vegetables like zucchini or bell peppers. They add color and freshness without competing with the bold flavors.

A simple arugula salad with lemon vinaigrette works beautifully too.

Final Thoughts

This lentil bolognese has become my go-to when I want something that feels indulgent but won’t leave me in a food coma.

The red lentils practically disappear into the sauce, creating this sneaky protein boost that keeps me satisfied for hours.

I love how forgiving this recipe is.

Forgot the wine? Use more broth.

No fresh basil? Dried works fine.

It’s the kind of dish that adapts to whatever’s lurking in your pantry.

Plus, it freezes beautifully, which means future-me gets to enjoy this comfort food magic without any effort whatsoever.
