Spaghetti With Lentil-Tomato Sauce And Spinach

A simple, light pasta dish with whole-wheat spaghetti, red lentils, tomatoes, carrot, celery, onion, garlic, spinach, and a small finish of Parmesan.

Slow-blood-sugar focus: Whole-wheat pasta plus lentils and vegetables adds fiber and protein, helping a steadier glucose response compared to refined pasta and sugary sauces.

Ingredients

  • Whole-wheat spaghetti, 160 g
  • Red lentils, 120 g
  • Canned chopped tomatoes (no added sugar), 400 g
  • Onion, 1 small, finely chopped
  • Carrot, 1 medium, finely diced
  • Celery, 1 stalk, finely diced
  • Garlic, 1 clove, finely chopped
  • Baby spinach, 80 g
  • Olive oil, 1 tsp
  • Tomato paste, 1 tbsp
  • Dried oregano, 1 tsp
  • Dried basil, 1 tsp
  • Salt, 1/2 tsp
  • Black pepper, 1/4 tsp
  • Parmesan, 20 g, finely grated
  • Water, as needed for sauce

Instructions

  1. Bring a pot of salted water to a boil and cook the whole-wheat spaghetti until al dente.
  2. While the pasta cooks, warm the olive oil in a pan, then cook onion, carrot, and celery for 6 to 8 minutes until softened.
  3. Add garlic and stir for 30 seconds, then add tomato paste and stir for 30 seconds.
  4. Add chopped tomatoes, red lentils, oregano, basil, salt, pepper, and 250 ml water. Simmer 12 to 15 minutes, stirring occasionally, until lentils are tender and the sauce is thick. Add a splash of water if it gets too thick.
  5. Stir in spinach for 1 minute until just wilted.
  6. Toss spaghetti with the sauce. Serve with Parmesan.

Notes

  • Red lentils cook quickly and thicken the sauce naturally, so you can keep it low fat without cream.
  • If you prefer a smoother sauce, mash a small part of the lentils against the pan with a spoon.

Variations

  • Swap spinach for kale or chard.
  • Add zucchini (small dice) with the carrot and celery.
  • Use passata instead of chopped tomatoes for a smoother texture.
  • Make it dairy-free by replacing Parmesan with nutritional yeast.
