Vegetable Lentil Marinara Pasta
A hearty, feel-good pasta where tender brown lentils meet a rich, garlicky tomato marinara loaded with finely diced carrots and zucchini. The lentils soak up all the herby, tangy sauce, giving you that satisfying meaty texture without the meat. It's a cozy weeknight dinner that comes together in one pot and tastes like it simmered all day.

- boil · ~25 min
Cook the lentils.
Combine the rinsed lentils with 3 cups of water in a medium saucepan. Bring to a boil over high heat, then reduce the heat to low, cover, and simmer for 20-25 minutes until the lentils are tender but still hold their shape. Drain any excess water and set aside.
TIPDon't overcook the lentils — they should be firm enough to stand up to the sauce without turning mushy. - boil · ~11 min
Boil the pasta.
Bring a large pot of water to a rolling boil. Add a pinch of salt and the pasta. Cook according to package directions until al dente. Reserve 1 cup of pasta water, then drain the pasta in a colander.
TIPScoop out the pasta water just before draining — that starchy liquid is liquid gold for loosening the sauce later. - saute · ~10 min

Simmer the marinara sauce.
1.Pour the fresh tomato puree into the skillet with the sautéed vegetables.2.Stir in the tomato paste, dried oregano, dried basil, and red chili flakes.3.Season with salt and bring the sauce to a gentle simmer.4.Cook uncovered for 15 minutes, stirring occasionally, until the sauce thickens and the vegetables are completely tender.TIPLet the sauce bubble gently — a hard boil makes it splatter and reduces it too fast. - mix · ~2 min
Combine the pasta, lentils, and sauce.
Add the cooked lentils and drained pasta directly into the skillet with the marinara sauce. Toss everything together, adding a splash of reserved pasta water if needed to achieve a glossy, clinging sauce consistency.

What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Cook the lentils just until tender so they keep their shape and texture in the final dish.
- 2Reserve a cup of pasta water before draining — its starch helps the sauce cling to every bite.
- 3Simmer the sauce uncovered for the full 15 minutes to deepen the tomato flavor and soften the veggies.
- 4Dice the carrot and zucchini uniformly small so they melt into the sauce and go unnoticed by picky eaters.
- 5Taste the sauce before adding the pasta and adjust salt and chili flakes to your preference.
- 6Leftovers keep well for 3 days in the fridge; add a splash of water when reheating to loosen the sauce.
