Ingredients

  • 12 ounces rotini pasta
  • 1 pound ground beef
  • 1 medium onion, diced
  • 3 cloves garlic, minced
  • 1 (24 ounce) jar marinara sauce
  • 1 (14.5 ounce) can diced tomatoes
  • 1/2 cup milk
  • 1 tablespoon Italian seasoning
  • 15 ounces ricotta cheese
  • 3 cups shredded mozzarella cheese, divided
  • 1/2 cup grated Parmesan cheese
  • 2 large eggs
  • 1 teaspoon salt
  • 1/4 teaspoon black pepper

Instructions

  • Preheat oven to 375°F and grease a 9x13 inch baking dish to prevent sticking.
  • Cook the rotini in salted boiling water until al dente but undercooked by 1 minute. Drain and set aside.
  • In a skillet, brown the ground beef until no longer pink.
  • Add the diced onion and minced garlic. Cook until translucent and aromatic (3-4 minutes).
  • Stir in marinara sauce, diced tomatoes (with juice), milk, and Italian seasoning. Simmer for 5 minutes.
  • Combine ricotta cheese, 1 cup mozzarella, Parmesan cheese, eggs, salt, and pepper in a bowl until well blended.
  • Layer cooked pasta evenly in the baking dish.
  • Pour half the meat sauce over the pasta layer.
  • Spread the ricotta mixture evenly over the meat sauce.
  • Top with remaining pasta and meat sauce.
  • Sprinkle the final 2 cups of mozzarella over the top.
  • Bake for 25-30 minutes until bubbly and golden. Let rest before cutting into sections.

Notes

Use gluten-free pasta if needed. Store leftovers in an airtight container for up to 3 days.
Substitute ground lamb or halal-certified beef for a more specific restriction.
Rotate the baking dish halfway through cooking for even browning.
