Ingredients

Scale

Protein Base:

  • 1 pound lean ground turkey or lean ground beef
  • 8 ounces (226 grams) high-protein spaghetti (chickpea, lentil, or whole wheat)
  • 1 small onion, diced
  • 3 cloves garlic, minced
  • 1 teaspoon olive oil

Sauce Ingredients:

  • 1 (28 ounces) can crushed tomatoes
  • 1 (15 ounces) can tomato sauce
  • 1 teaspoon dried oregano
  • 1 teaspoon dried basil
  • 1/2 teaspoon red pepper flakes (optional)
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper

Cheese and Toppings:

  • 1 cup low-fat cottage cheese or ricotta cheese
  • 1/2 cup plain Greek yogurt
  • 1/2 cup shredded mozzarella cheese
  • 1/4 cup grated Parmesan cheese
  • 2 tablespoons chopped fresh parsley (optional)

Instructions

  1. Prepare the oven by heating to 375F (190C), ensuring an even cooking environment for the casserole.
  2. Cook the spaghetti in boiling water until al dente, then drain thoroughly and set aside for layering.
  3. Heat olive oil in a large skillet over medium temperature. Add ground turkey or beef with diced onions and minced garlic, breaking down the meat while cooking until it achieves a rich brown color and releases its savory essence.
  4. Create a robust sauce by incorporating crushed tomatoes, tomato sauce, and a blend of herbs including oregano, basil, red pepper flakes, salt, and pepper. Allow the mixture to simmer for 10 minutes, intensifying the flavor profile.
  5. Craft a creamy filling by blending cottage cheese, Greek yogurt, and half of the Parmesan cheese until smooth and well-integrated.
  6. Construct the casserole in a greased 9×13-inch baking dish by strategically layering spaghetti, meat sauce, and cheese mixture. Repeat the layering process to create a harmonious composition of flavors and textures.
  7. Crown the casserole with a generous sprinkle of shredded mozzarella and remaining Parmesan cheese, ensuring complete coverage.
  8. Bake in the preheated oven for 20-25 minutes until the top turns golden brown and the edges become delightfully bubbly.
  9. Enhance the presentation by garnishing with fresh parsley if desired, and serve immediately while the casserole remains piping hot.

Notes

  • Swap ground turkey with plant-based crumbles for a vegetarian version that maintains high protein content and delivers similar texture and flavor.
  • Greek yogurt provides extra protein boost and creates creamier sauce while cutting down on traditional heavy cream calories.
  • Consider using whole wheat spaghetti to increase fiber intake and enhance nutritional profile without compromising taste.
  • Prepare casserole ahead of time by assembling and refrigerating up to 24 hours before baking, which makes meal planning easier and saves cooking time.
