Description

Perfect for family dinners, it combines savory ground beef, aromatic herbs, and creamy cheeses for a flavorful, satisfying meal.


Ingredients

Scale

Sauce

  • 32 oz marinara sauce, high quality
  • ½ cup half and half
  • 1 teaspoon Worcestershire sauce
  • 1 teaspoon hot sauce
  • ¾ teaspoon dried oregano
  • ¾ teaspoon dried basil
  • ¾ teaspoon dried parsley
  • ¾ teaspoon mustard powder

Casserole

  • 1 lb ground beef
  • Salt and pepper, to taste
  • 1 small yellow onion, diced
  • 3 cloves garlic, minced
  • 1 tablespoon tomato paste
  • ½ cup beef broth
  • ¼ cup Parmesan cheese, grated
  • 2 cups mozzarella cheese, divided (low moisture, whole milk, shredded)
  • ¾ lb penne pasta

Instructions

  1. Prepare the sauce: Combine the marinara sauce, half and half, Worcestershire sauce, hot sauce, dried oregano, basil, parsley, and mustard powder in a bowl and set aside.
  2. Preheat oven and boil pasta water: Preheat your oven to 375° F. Bring a large pot of salted water to a boil for the pasta, adding ¾ tablespoon salt once boiling.
  3. Cook ground beef mixture: Season ground beef with salt and pepper. Heat a large skillet over medium-high heat, add ground beef and cook, crumbling for about 3 minutes. Add diced onions and minced garlic; cook and stir until onions soften and beef is fully cooked, approximately 5 to 6 minutes. Drain excess grease thoroughly.
  4. Add tomato paste and broth: Stir in tomato paste and cook for 1 to 2 minutes. Pour in beef broth and scrape the bottom and sides of the skillet with a silicone spatula to incorporate the browned bits. Allow mixture to bubble gently and reduce the liquid by half, about 3 to 4 minutes.
  5. Combine sauce and simmer: Add the prepared sauce mixture to the skillet, bringing it to a gentle boil before reducing to a simmer. Let it simmer uncovered while boiling pasta to al dente to ensure flavors meld.
  6. Incorporate cheeses: Stir Parmesan cheese and ¼ cup of mozzarella into the sauce continuously until melted and combined.
  7. Cook pasta and combine: Drain the cooked pasta and add it directly to the sauce. Toss thoroughly to coat the pasta evenly with the sauce.
  8. Assemble casserole: Transfer the pasta and sauce mixture to a lightly greased 9 x 13-inch casserole dish. Sprinkle the remaining 1¾ cups mozzarella evenly over the top.
  9. Bake and broil: Bake uncovered at 375° F for 10 minutes. For a browner, bubbly top, broil at 450° F for 1 to 2 minutes, watching carefully to prevent burning.
  10. Garnish and serve: Remove casserole from the oven, garnish with fresh parsley, and let it stand for 5 minutes before serving. Enjoy with garlic bread with cheese for a complete meal.

Notes

  • Use a high-quality marinara sauce such as Rao’s for best flavor.
  • Low moisture, whole milk mozzarella shredded from a block melts best and tastes superior; Dragone or Galbani brands recommended.
  • Alternative pasta shapes like ziti or rigatoni work well in this recipe.
  • You can substitute or combine ground pork, veal, sausage, or beef according to preference.
  • Optional additions include diced green bell pepper, sliced mushrooms (add with onions), or drained diced tomatoes/Rotel (add with sauce) for extra flavor and texture.
  • Mustard powder and hot sauce are subtle flavor enhancers; regular yellow mustard can substitute mustard powder if needed. Frank’s Hot Sauce is suggested for heat.
  • To make ahead, undercook pasta by 1 minute less than al dente, assemble, cool, and refrigerate covered for up to 2 days. Bake covered at 350° F for 15 minutes, then uncovered for 10 minutes before serving.
  • Store leftovers in an airtight container refrigerated for up to 3 days or freeze for up to 3 months. Do not overcook pasta to maintain texture on reheating.
