Instructions

Step 1: Preheat oven to 375°F (190°C). Lightly grease a 9x13-inch sheet pan. Spread 1 cup marinara sauce evenly over the bottom of the pan.
Step 2: Arrange 3 no-boil lasagna noodles in a single layer over the sauce. Dollop 1/3 cup ricotta cheese evenly over the noodles and sprinkle 1 cup shredded mozzarella cheese on top.
Step 3: Repeat layering with 1 cup marinara, 3 noodles, 1/3 cup ricotta, and 1 cup mozzarella. Top the final 3 noodles with remaining 1 cup marinara, 1/3 cup ricotta, 1 cup mozzarella, and sprinkle 1/2 cup grated Parmesan cheese evenly.
Step 4: Cover loosely with foil and bake for 40 minutes. Remove foil and bake an additional 10 minutes until cheese is bubbly and golden around edges. Let cool 10 minutes before slicing and serving.
