3. Cook the Lasagna Noodles

1. Bring a large pot of salted water to a boil.
2. Cook lasagna noodles according to package instructions until al dente.

3. Layer 3 lasagna noodles on top.

5. Add ¼ of the meat sauce and sprinkle with ½ cup mozzarella cheese.
6. Repeat layers two more times, finishing with noodles, meat sauce, and the remaining mozzarella and Parmesan cheese.

5. Bake & Serve

1. Cover with foil (spray foil with cooking spray to prevent sticking).
2. Bake for 25 minutes, then uncover and bake for another 15 minutes until the cheese is bubbly and golden.
3. Let the lasagna rest for 10 minutes before slicing.
4. Garnish with fresh basil or parsley and serve warm!
