Sauté the Vegetables:
Heat the olive oil in a large pot over medium heat.
Add the chopped onion, garlic, carrots, and celery. Sauté for 5-7 minutes until softened and the onions are translucent.
Add Lentils and Tomatoes:
Stir in the rinsed red lentils, crushed tomatoes, and tomato paste. Mix until the lentils are coated.
Add Broth and Seasonings:
Pour in the vegetable broth. Add the oregano, basil, salt, and pepper. Stir well.
Simmer the Sauce:
Bring the mixture to a boil, then reduce the heat to low.
Simmer uncovered for 25-30 minutes, stirring occasionally, until the lentils cook and the sauce thickens. Add more broth or water if needed.
Adjust Seasoning:
Taste the bolognese and adjust the seasoning with more salt, pepper, or herbs as needed.
For added heat, sprinkle in red pepper flakes.
Serve and Garnish:
Serve the bolognese over your favorite pasta.
Garnish with fresh basil, nutritional yeast, or vegan Parmesan.
