Ingredients

Scale

Protein:

  • 1 lb ground beef
  • 1½ cups shredded cheddar cheese
  • ½ cup grated Parmesan cheese

Carbohydrates:

  • 12 ounces medium pasta shells
  • 1 small onion (diced)
  • 2 tablespoons tomato paste

Seasonings and Liquids:

  • 1 tablespoon olive oil
  • 3 cloves garlic (minced)
  • 1 teaspoon Italian seasoning
  • 1 teaspoon paprika
  • 1 cup beef broth
  • 1 cup heavy cream
  • Salt and pepper to taste
  • Optional: cooked spinach (mushrooms, bell peppers, fresh parsley)

Instructions

  1. Boil 12 oz medium pasta shells in generously salted water for 8-9 minutes until tender. Drain and set shells aside in a colander.
  2. Warm 1 tbsp olive oil in a large skillet over medium heat. Sauté the diced small onion for 3-4 minutes until translucent and softened.
  3. Add 3 minced garlic cloves to the skillet. Stir quickly for 30 seconds to release their aromatic flavors without burning.
  4. Introduce 1 lb ground beef to the skillet. Break the meat into small crumbles and cook for 6-7 minutes until completely browned and no pink remains.
  5. Stir 2 tbsp tomato paste, 1 tsp Italian seasoning, and 1 tsp paprika into the meat mixture. Ensure the seasonings coat the beef evenly.
  6. Pour 1 cup beef broth and 1 cup heavy cream into the skillet. Allow the mixture to simmer for 5 minutes, creating a rich, creamy sauce.
  7. Reduce heat to low. Blend in 1½ cups shredded cheddar cheese and ½ cup grated Parmesan cheese until completely melted and smooth.
  8. Season the sauce with salt and pepper to taste. Gently fold the cooked pasta shells into the creamy beef mixture.
  9. Transfer the entire mixture to a casserole dish. Spread it evenly to ensure consistent coverage.
  10. Bake uncovered at 375°F for 15-20 minutes until the top is golden and the edges are bubbling.
  11. Remove from the oven and let the casserole rest for 5 minutes. Sprinkle with fresh chopped parsley before serving.

Notes

  • Don’t overcook the pasta shells, as they’ll continue cooking in the oven and can become mushy if boiled too long.
  • For a lighter version, swap ground beef with ground turkey or use a plant-based meat alternative to reduce fat content.
  • Grate your own cheese instead of using pre-shredded to get a smoother, more creamy sauce that melts more evenly.
  • Let the casserole rest for 5-10 minutes after baking to help the sauce set and make serving easier without falling apart.
