Ingredients

  • 1 pound Spaghetti Noodles
  • 1 pound Lean Ground Beef
  • ½ Yellow Onion diced
  • 4 cloves Garlic Minced or 1 Tablespoon minced garlic
  • 4 cups Marinara Sauce
  • 1 teaspoon Italian Seasoning
  • 1 teaspoon Salt
  • ½ teaspoon Black Pepper
  • ½ teaspoon Red Pepper Flakes optional
  • 2 cups Shredded Mozzarella Cheese
  • ½ cup Grated Parmesan Cheese
  • Fresh Chopped Parsley optional

Instructions

  • Preheat the oven to 350 degrees F.
  • Cook 1 pound spaghetti noodles 2 minutes less than al dente based on the package instructions. Drain the pasta and place it in the bottom of a 9x13 baking dish.
  • Brown 1 pound lean ground beef with ½ diced yellow onion in a large skillet over medium high heat. Break up the beef as it browns and cook until the beef is no longer pink. Drain off any excess grease.
  • Stir in 4 cloves minced garlic or 1 tablespoon minced garlic and cook for 1 minute until aromatic.
  • Stir in 4 cups marinara sauce, 1 teaspoon Italian seasoning, 1 teaspoon salt, ½ teaspoon black pepper, and ½ teaspoon red pepper flakes. Cook for a few minutes until the sauce is heated through.
  • Pour the beef mixture on top of the noodles in the baking dish.  Toss the beef mixture with the noodles until the noodles are coated with the beef and sauce.
  • Smooth the mixture into an even layer.
  • Top with 2 cups shredded mozzarella cheese and ½ cup grated Parmesan cheese. Bake uncovered for 15 to 20 minutes until the top of the casserole starts to brown.
  • Remove from the oven, let it rest for 5-10 minutes. Cut into squares, serve warm topped with the chopped parsley and enjoy!

Notes

Refrigerate any leftovers in an airtight container for up to 5 days. 
Shred your own cheese instead of using pre-shredded so that it melts smoothly and for the best flavor in this recipe.
