Ingredients

Scale

Proteins:

  • 1 pound (454 grams) lean ground turkey
  • 1/4 cup (30 grams) grated Parmesan cheese (optional)

Vegetables and Aromatics:

  • 1 onion, finely chopped
  • 2 cloves garlic, minced
  • 1 bell pepper, chopped
  • 1 zucchini, chopped

Canned Ingredients and Seasonings:

  • 1 can (14.5 ounces/411 grams) crushed tomatoes
  • 1 can (6 ounces/170 grams) tomato paste
  • 1 can (14.5 ounces/411 grams) diced tomatoes
  • 1 teaspoon dried basil
  • 1 teaspoon dried oregano
  • 1 teaspoon Italian seasoning
  • Salt, to taste
  • Pepper, to taste
  • 8 ounces (227 grams) whole wheat spaghetti (or gluten-free pasta)

Instructions

  1. Brown ground turkey in a skillet over medium heat until fully cooked, breaking it into small crumbles.
  2. Sauté chopped onion, garlic, bell pepper, and zucchini for 3-4 minutes until vegetables turn slightly translucent and tender.
  3. Incorporate crushed tomatoes, tomato paste, diced tomatoes, and season with basil, oregano, Italian seasoning, salt, and pepper. Stir thoroughly to combine all ingredients.
  4. Transfer the seasoned meat and vegetable mixture into the slow cooker, ensuring even distribution.
  5. Cover and simmer on low temperature for 4-6 hours or on high for 2-3 hours, allowing flavors to meld and develop depth.
  6. During the last 30 minutes of cooking, prepare whole wheat spaghetti according to package instructions, cooking until al dente.
  7. Drain pasta completely and let it rest briefly to prevent wateriness.
  8. Plate the pasta, generously ladle the rich meat sauce over the noodles, and garnish with freshly grated Parmesan cheese if desired.
  9. Serve immediately while the sauce is hot and the pasta is steaming.

Notes

  • Use lean ground turkey to reduce fat and create a healthier protein base for the sauce.
  • Finely chop vegetables like zucchini and bell peppers to hide them from picky eaters while boosting nutritional value.
  • Allow sauce to simmer slowly in the slow cooker to develop deeper, richer flavors and tenderize the meat.
  • Consider using gluten-free pasta or spiralized vegetables like zucchini noodles for low-carb or gluten-sensitive diets.
