Ingredients

Scale
  • 1 pound ground beef
  • 1 onion, chopped
  • 2 cloves garlic, minced
  • 1 (24 ounce) jar marinara sauce
  • 1 (15 ounce) can diced tomatoes, undrained
  • 1 (16 ounce) box rotini pasta, uncooked
  • 1 (15 ounce) container cottage cheese
  • 1 egg
  • 1 teaspoon Italian seasoning
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 2 cups shredded mozzarella cheese
  • 1/2 cup grated Parmesan cheese

Instructions

  1. Preheat your oven to 375°F (190°C).
  2. In a large skillet, cook the ground beef and chopped onion over medium heat until the beef is browned and the onion is softened. Drain off any excess grease. Add the minced garlic and cook for 1 more minute until fragrant.
  3. Stir in the marinara sauce and diced tomatoes. Bring the mixture to a simmer.
  4. Add the uncooked rotini pasta to the skillet, stirring to combine with the sauce. Ensure the pasta is mostly submerged in the liquid.
  5. In a medium bowl, mix together the cottage cheese, egg, Italian seasoning, salt, and pepper until well combined.
  6. Spread the cottage cheese mixture evenly over the pasta mixture in the skillet.
  7. Sprinkle the mozzarella cheese and Parmesan cheese over the top.
  8. Cover the skillet tightly with foil.
  9. Bake for 45 minutes, or until the pasta is tender and the sauce is bubbly.
  10. Remove the foil and bake for an additional 10-15 minutes, or until the cheese is melted and golden brown.
  11. Let the casserole rest for 5-10 minutes before serving.

Notes

  • You can substitute ricotta cheese for cottage cheese if preferred.
  • This casserole can be assembled ahead of time and refrigerated or frozen for later. If baking from frozen, add an additional 15-20 minutes to the covered baking time.
  • Leftovers reheat well in the microwave or oven.
