Ingredients

Scale

Main Proteins:

  • 1 pound ground beef
  • 0.5 pound Italian sausage

Main Starches:

  • 12 ounces medium pasta shells

Supporting Ingredients:

  • 0.5 medium onion, finely chopped
  • 3 cloves garlic, minced
  • 1 teaspoon Italian seasoning
  • 0.5 teaspoon smoked paprika
  • 0.5 teaspoon salt
  • 0.5 teaspoon black pepper
  • 1 (14 ounces) can diced tomatoes
  • 1 (15 ounces) can tomato sauce
  • 0.5 cup heavy cream
  • 0.5 cup beef broth
  • 1 cup shredded cheddar cheese
  • 1 cup shredded mozzarella cheese
  • 2 tablespoons chopped fresh parsley or basil

Instructions

  1. Salt 8 cups of water in a large pot and bring to a rolling boil at 212°F. Submerge 12 ounces of pasta shells and cook for 8-9 minutes until al dente.
  2. Drain pasta in a colander and set aside while reserving ¼ cup of pasta water.
  3. Heat a large skillet to medium-high and add 1 pound ground beef and ½ pound Italian sausage. Break meat into small crumbles.
  4. Cook meat for 6-7 minutes until brown, releasing fat and developing deep flavor.
  5. Add ½ chopped onion and 3 minced garlic cloves. Stir continuously for 2 minutes.
  6. Sprinkle 1 teaspoon Italian seasoning, ½ teaspoon smoked paprika, ½ teaspoon salt, and ½ teaspoon black pepper over the meat mixture.
  7. Pour off excess grease from the skillet to prevent a soggy casserole.
  8. Pour 14 ounces diced tomatoes, 15 ounces tomato sauce, ½ cup heavy cream, and ½ cup beef broth into the skillet.
  9. Simmer sauce at medium heat for 5 minutes, stirring occasionally until slightly thickened.
  10. Fold cooked pasta shells into the sauce, ensuring even coating.
  11. Transfer mixture to a greased 9×13-inch baking dish.
  12. Preheat oven to 375°F with rack in center position.
  13. Distribute ½ cup cheddar cheese and ½ cup mozzarella cheese across the top of the casserole.
  14. Bake uncovered for 22 minutes until cheese melts and edges turn golden brown.
  15. Remove from oven and let rest for 5 minutes to set and cool slightly.
  16. Garnish with 2 tablespoons freshly chopped parsley or basil before serving.

Notes

  • Drain the pasta just shy of al dente, as it will continue cooking in the sauce and baking process to prevent mushy texture.
  • Use freshly grated cheese for better melting and richer flavor compared to pre-shredded packaged cheese.
  • For a lower-carb version, swap pasta shells with cauliflower florets or zucchini noodles to reduce overall carbohydrate content.
  • If preparing ahead, assemble the casserole and refrigerate up to 24 hours, adding 10-15 minutes to baking time when ready to cook.
