Step 1

Heat a large oven-proof skillet over medium-high heat. Add the ground beef and cook, stirring, until browned and crumbly, about 5 to 7 minutes. Drain any excess grease.

Step 2

Stir in the spaghetti sauce, diced tomatoes, chopped onion, minced garlic, dried basil, dried oregano, salt, and black pepper. Reduce the heat to low and simmer for about 15 minutes.

Step 3

While the sauce simmers, fill a large pot with lightly salted water and bring it to a rolling boil. Add the broken lasagna sheets and cook until tender yet firm to the bite, about 8 minutes. Drain the pasta.

Step 4

Add the cooked lasagna pieces to the skillet with the sauce. Stir well to ensure the pasta is completely coated with the sauce.

Step 5

Sprinkle the shredded mozzarella and grated Parmesan cheese evenly over the top of the skillet.

Step 6

Position an oven rack about 6 inches from the heat source and preheat the broiler. Place the skillet under the hot broiler and cook until the cheese is golden and bubbly, about 3 to 5 minutes. Remove the skillet from the oven and let it cool slightly.

Step 7

Just before serving, garnish with fresh basil and additional Parmesan cheese if desired. Serve and enjoy!
