Instructions

1
Rinse the red lentils thoroughly. In a medium pot, combine the rinsed lentils and chicken broth. Bring to a simmer, cover, and cook until the lentils are very soft, about 15-20 minutes.
2
While the lentils are cooking, bring a large pot of salted water to a boil and cook your pasta according to package directions. Also, dice the onion and grate the Parmesan cheese.
3
Once the lentils are cooked, set them aside. In a large skillet or pan, heat the olive oil over medium heat. Add the diced onion and minced garlic, and sauté until softened and fragrant.
4
Stir in the tomato paste and cook for about a minute until it darkens in color.
5
Add the cooked lentil mixture to the skillet.
6
Use an immersion blender to blend the sauce directly in the pan until it's completely smooth. If the sauce is too thick, add a splash of reserved pasta water and blend again to reach your desired consistency.
7
Stir in the paprika, red pepper flakes, dried oregano, and black pepper.
8
Pour in the heavy cream and stir until fully combined.
9
Add the grated Parmesan cheese and stir until it has melted into the sauce.
10
Drain the cooked pasta and add it to the skillet with the sauce. Toss everything together until the pasta is well-coated.
11
Serve immediately, garnished with additional red pepper flakes and grated Parmesan cheese.

Tips & Notes

Pro tips

Stir the red lentils occasionally while simmering to prevent sticking to the bottom of the pot and ensure even cooking.
Mash or partially blend the cooked lentil mixture against the side of the pot to reach your desired sauce consistency—more blended for ultra-creamy, less for a chunkier texture.
Toast the paprika and red pepper flakes briefly in olive oil before adding onion to bloom the spices and deepen their flavor.
Add the sauce to hot, drained pasta immediately rather than letting it sit, as lentil-based sauces thicken as they cool.

Substitutions

Chicken broth → vegetable broth (maintains creaminess, shifts to vegetarian)
Red pepper flakes → cayenne pepper or chili powder (adjust quantity—cayenne is hotter, use ½ tsp to start)
Short pasta → penne, rigatoni, or fusilli (any shape holds the thick sauce well)

Storage & make-ahead

Store cooled sauce in an airtight container in the fridge for up to 3 days. Reheat gently on the stovetop with a splash of water if needed, and toss with freshly cooked or warmed pasta.

Common Questions

Why use red lentils instead of cream in this pasta sauce?

Red lentils break down completely when cooked, creating a naturally thick and creamy texture while adding fiber, plant-based protein, and nutrients. They also eliminate the need for heavy cream.

Can I make this pasta ahead of time?

Yes. Store the sauce separately from cooked pasta in an airtight container in the fridge for up to 3 days. Reheat the sauce gently on the stovetop and toss with fresh or warmed pasta to prevent mushiness.

How do I know when the red lentils are fully cooked?

Red lentils are done when they're completely soft and beginning to fall apart, usually 20–25 minutes in simmering broth. They should have no firm center when mashed against the side of the pot.

Can I substitute the chicken broth?

Yes. Vegetable broth works well for a vegetarian version. Beef broth will deepen the flavor. Water is not recommended as it lacks the savory base needed for the sauce.

How spicy is this dish?

With 1 teaspoon of red pepper flakes in the full recipe, the heat is moderate. Reduce it to ½ teaspoon for mild, or increase to 1½ teaspoons for extra spice.
