Lentil Bolognese in a pasta bowl

This lentil bolognese sauce is hearty, healthy, and out-of-this-world delicious. The lentils give it a meaty texture so we promise you won't miss the meat!

We love lentils because they're packed with protein, iron, fiber, and other nutrients. They're like an everyday superfood and they cook quickly, too.

The thing about lentils is they're pretty much flavorless. So to make up for it, we use caramelization and miso paste to add more umami. This gives it a deep, rich, and complex flavor unlike many lentil bolognese recipes out there.

This lentil bolognese makes a delicious and healthy weeknight meal that everyone (meat eaters included) enjoys. You can easily prepare the sauce ahead of time, and even double the batch and freeze some for later!

How to make lentil bolognese

This vegan lentil bolognese is healthy, hearty, and flavorful. It makes a great weeknight dinner, and it's easy to prepare ahead of time. Here's how we make it in a few simple steps:

  1. To make the sauce, we cook the onions, carrots, and red bell peppers until they're golden and caramelized. Then we add the tomato paste and garlic and caramelize them too.
  2. Next goes the miso, lentils, and water into the pot to simmer until the lentils are soft. Toss in the fresh cherry tomatoes at the end and cook until they soften.
  3. Serve the lentil bolognese over some cooked pasta, and top with some parmesan cheese, fresh sage or basil, and some black pepper.

What is miso paste?

This is the secret ingredient that steps this lentil bolognese up to the next level. But what exactly is it? Miso is a fermented soybean paste. It's a traditional Japanese ingredient that's salty and earthy and adds umami flavor to a variety of dishes. We use it in this meatless recipe to mimic the richness of a traditional meat-based sauce.

You can find it at most well-stocked grocery stores in the refrigerated aisle or at any Japanese or Asian market.

Lentil bolognese ingredients

This vegan pasta sauce is filled with real, good-for-you ingredients. Here's everything you need to make this hearty lentil bolognese recipe:

  • Pasta – we use rotini pasta in the pictures, but you can use spaghetti, penne, or any pasta you like. Use gluten-free pasta if needed.
  • Olive oil – extra-virgin olive oil is the least processed form of olive oil and is the perfect Italian choice for sautéing veggies.
  • Onion + garlic cloves – for that classic savory flavor base.
  • Carrots + red bell pepper – we use a mix of carrots and bell pepper but you can use other veggies like mushrooms, celery, or zucchini.
  • Sea salt + sugar – sea salt makes all the flavors pop, and a little sugar helps balance the acidity of the tomatoes.
  • Tomato paste – tomato paste is basically tomato concentrate and adds an intense tomato flavor.
  • Miso – miso paste might seem like a surprising ingredient, but its rich umami taste adds depth and complexity to this sauce.
  • Dried brown lentils – dried brown lentils are packed with fiber and nutrition, and they cook relatively quickly. They also give provide the best texture for this sauce. You can use canned lentils in a pinch, but add them towards the end or they will fall apart during cooking.
  • Cherry tomatoes – we use fresh cherry tomatoes instead of canned tomatoes for their juicy and fresh flavor.
  • Grated parmesan (regular or vegan), sage leaves, black pepper – we use sage but you can also use other fresh herbs like basil or oregano instead.

Recipe FAQs

Can I substitute red lentils?

We don't recommend it because red lentils have quite a different texture. You can try them in a pinch, but make sure to adjust the cooking time because they soften in about half the time.

Can I use other tomatoes in place of cherry tomatoes?

Yep, you can substitute an equal amount of any fresh tomato variety. Roma tomatoes are classic Italian tomatoes, but you can use any variety.

How long does it keep in the fridge?

Allow it to cool completely at room temperature, then store any leftover bolognese sauce in an airtight container in your refrigerator for 3-4 days.

Can I freeze lentil bolognese?

Yes, this sauce freezes beautifully. Store it in an airtight container in your freezer for up to 3 months! Thaw it in your fridge overnight when you're ready to use it.
