Equipment

9 x 13-Inch Baking Dish (this is my favorite option with a lid)
5.5 Quart Dutch Oven

Ingredients

2 teaspoons olive oil
8 ounces sliced mushrooms
1 zucchini, diced
1 sweet bell pepper (any color), seeded and diced
1 onion, diced
1 tablespoon minced fresh garlic
1 egg, beaten
2 tablespoons chopped fresh parsley (or 2 teaspoons dried parsley flakes)
2 tablespoons chopped fresh basil (or 2 teaspoons dried basil)
15 ounces ricotta cheese (or sub with 16 ounces small curd cottage cheese)
2 ¼ cups grated mozzarella cheese, divided
½ cup grated Parmesan cheese, divided
24 ounces (2 ½ cups) store-bought (or homemade) marinara sauce
9 oven-ready, no-boil lasagna noodles (or as many noodles as needed to fit your dish)

Instructions

Preheat oven to 400 degrees F. Spray a 9 x 13-inch baking dish with cooking spray and set aside.
In a large skillet or Dutch oven, heat oil over medium-high heat. Add mushrooms, zucchini, bell pepper, onion, and garlic. Cook and stir the veggies just until tender (about 3-5 minutes).
While the veggies cook, use a separate bowl to stir together egg, parsley, basil, ricotta cheese, 1 ¼ cups mozzarella, and ¼ cup Parmesan.
When the vegetables are done cooking, stir the marinara sauce into the skillet.
Spread ¼ of the marinara-vegetable sauce mixture in a thin layer in the bottom of the prepared baking dish. Top with 3 no-boil lasagna noodles (or as many as you need to cover a single layer in the dish), ⅓ of the ricotta mixture, and another ¼ of the sauce mixture.
Repeat layers two more times. Finish with remaining 1 cup of mozzarella and ¼ cup of Parmesan cheese on top. Cover with a piece of greased foil.
Bake for 35 minutes. Remove foil, and bake for another 5-10 minutes (or until heated through and cheese on top is browned). Let stand for about 10 minutes before slicing and serving.

Notes

Make Ahead

Assemble the lasagna in advance, but do not bake. Wrap tightly and store in the refrigerator for up to 48 hours before baking, or freeze for up to 3 months.

When ready to bake, allow the refrigerated lasagna to sit on the counter and come to room temperature for at least 30-60 minutes before baking. If you're baking the casserole frozen (directly from the freezer), bake the dish covered in a 400° F oven for 1 hour. Then remove the cover and bake for an additional 10 minutes (or until the pasta is tender and the dish is heated through).

Storage

Leftover lasagna will keep in an airtight container in the refrigerator for 3-4 days. You can also freeze the leftovers in an airtight container for up to 3 months.

To Reheat

Cover the lasagna loosely with foil. Warm the dish in a 350° F oven just until heated through, about 30 minutes. You can also reheat individual slices of lasagna in the microwave until warm, about 1 minute.
