Healthy Lentil Bolognese Sauce

Sharing is caring!

Spaghetti is a weekly staple in our house, but I often turn to canned sauces like Prego or Barilla to save time. However, this Bolognese sauce is really easy to make and it tastes delicious. Best of all, it’s a frugal, protein-packed version of the canned tomato sauce (it also doesn’t contain all the salt and preservatives that come in canned versions).

If you’re looking for a healthier or vegetarian alternative to your usual spaghetti or Bolognese sauce, you’ll fall in love with this recipe, especially since it contains a lot of hidden vegetables – perfect for kids who are picky eaters but still need to eat their veggies.

While the recipe calls for grated carrots, I often cheat and just chop the carrots as thin as possible. My brother recommended this chopper and grater to make meal prep go a little faster. ?

If you love freezer cooking or batch cooking, this sauce is also great to make ahead. You can even double or triple the batch to create a stockpile and freeze it for quick, easy weeknight dinners.

Lentil Bolognese Sauce


  • 1 onion chopped
  • 2 celery sticks thinly sliced
  • 2 carrots grated or finely chopped
  • 2 garlic cloves minced
  • 3 tbsp olive oil
  • 2/3 cup red lentils
  • 1 14 oz. can chopped tomatoes
  • 2 tbsp tomato paste
  • 2 cups vegetable broth
  • 1 tsp Italian spices or 1 drop of Taste of Italy essential oil
  • salt and pepper to taste (I often skip the salt, especially if the broth isn't low sodium)


  1. In a large saucepan, heat the olive oil and saute the carrots, onion, garlic, and celery until they are tender, about 5 minutes. 

  2. Add the rest of the ingredients. Season with salt and pepper to taste. 

  3. Bring to a quick boil, then reduce heat and simmer for about 20 minutes until the lentils are soft and the sauce has thickened.
