To make Easy Sheet Pan Lasagna, follow these straightforward steps:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Cook Meat: In a skillet over medium heat, cook the ground beef or sausage until browned. Drain excess fat if necessary.
3. Cook Noodles: Boil a large pot of salted water and cook the lasagna noodles according to package instructions until al dente. Drain and set aside.
4. Mix Cheese Filling: In a separate bowl, combine ricotta cheese, egg, Italian herbs, salt, and pepper. Mix until smooth.
5. Layer 1: Spread a thin layer of marinara sauce on the bottom of the sheet pan to prevent sticking.
6. Layer 2: Lay down 4 lasagna noodles in a single layer on the sauce.
7. Layer 3: Spread half of the ricotta mixture over the noodles, followed by half of the cooked meat and a third of the mozzarella cheese.
8. Layer 4: Add another layer of noodles, followed by the remaining ricotta, meat, and another portion of sauce.
9. Layer 5: Place the last layer of noodles on top, cover with the remaining marinara sauce, and top with the remaining mozzarella and Parmesan cheese.
10. Bake: Cover the sheet pan with aluminum foil and bake in the preheated oven for 30 minutes.
11. Uncover and Finish: Remove the foil and bake for an additional 10-15 minutes, until the cheese is bubbly and golden.
12. Cool: Let the lasagna cool for about 10-15 minutes before slicing.
13. Garnish: Optional – garnish with fresh basil before serving.
