Not draining noodles properly: Make sure noodles are well-drained to avoid a watery casserole.
Recipe Variations

Instructions
1- Preheat the oven to 400°F (200°C). Lightly coat a large baking sheet with cooking spray.

7- To assemble the lasagna, spread ⅓ cup of pasta sauce in the bottom of a 9×13-inch baking dish.
8- Layer 3 lasagna noodles over the sauce.
9- Spread ¼ of the roasted vegetables evenly over the noodles.
10- Top with ¼ of the pasta sauce and sprinkle ¼ of the cheese mixture over the sauce.
11- Repeat the layering process three more times, ending with a generous topping of the cheese mixture.
12- Bake in the preheated oven until the cheese is melted and the sauce is bubbly, about 20 to 25 minutes.
13- Allow the lasagna to rest for 10 minutes before slicing and serving.
