Equipment

Ingredients

8 –9 oz spaghetti
½ cup red lentils split skin
1 tsp olive oil
½ small onion finely diced
4 cloves garlic minced
4 oz mushrooms finely chopped
¼ cup shredded carrots
¼ tsp dried thyme
¾ tsp dried oregano
1 tsp dried basil
1 –2 tsp tomato paste optional
16 –18 oz marinara or crushed tomatoes
¼ cup red wine or vegetable broth + 2 tsp balsamic vinegar
Salt black pepper, red pepper flakes, to taste
Fresh basil for garnish

Instructions

Cook spaghetti separately according to package instructions until al dente. Drain and set aside.
Heat olive oil in a large skillet over medium heat. Sauté onion, garlic, carrots, and mushrooms until softened, about 5-7 minutes.
Add dried thyme, oregano, basil, and tomato paste. Stir continuously for 1 minute until fragrant.
Pour in red wine (or vegetable broth with balsamic vinegar). Cook until liquid reduces by half, about 2-3 minutes.
Add red lentils and marinara sauce. Bring to a simmer and cook for 15–20 minutes until lentils are tender and sauce has thickened.
Season with salt, black pepper, and red pepper flakes to taste.
Serve sauce over cooked spaghetti and garnish with fresh basil.

Notes

Red lentils break down during cooking, creating a meat-like texture that blends seamlessly into the sauce

Substitute red wine with additional vegetable broth plus balsamic vinegar for an alcohol-free version

Finely chopping vegetables guarantees they integrate well into the sauce for picky eaters

This sauce freezes beautifully for up to 3 months in portioned containers

For extra depth, add a parmesan rind while simmering (remove before serving)

Double the recipe and freeze half for an easy future meal

If sauce becomes too thick, thin with pasta water or additional broth
