Instructions
- 01
Preheat oven to 400°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). Season with salt and pepper to taste.
- 02
While the veggies cook, use a separate bowl to stir together egg, parsley, basil, ricotta cheese, 1 ¼ cups mozzarella, and ¼ cup Parmesan.
- 03
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.
- 04
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.
- 05
Repeat layers two more times. Finish with remaining 1 cup of mozzarella and ¼ cup of Parmesan cheese on top.
- 06
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. Garnish with chopped fresh herbs if desired.

Recipe Variations
- Cooking for Two? Divide the full recipe between two smaller 8-inch square baking dishes. That way you get two meals with the same amount of effort, and you can freeze one for a later date. Alternatively, you can cut all of the ingredients in half and prepare one lasagna in an 8-inch square dish. The baking instructions remain the same.
- Add meat to this veggie-packed lasagna by stirring 1 pound of cooked ground beef or Italian sausage into the sauce.
- Make it spicy by adding crushed red pepper flakes to the veggies and marinara.
- White Vegetarian Lasagna: substitute a jar of store-bought Alfredo sauce or 2 ½ cups of homemade Alfredo sauce for the marinara sauce.
- Make vegetable lasagna with spinach by adding a few cups of fresh baby spinach leaves to the warm sauce, just until the leaves wilt. Alternatively, you can use a 10-ounce package of chopped, frozen spinach. Just thaw the spinach and squeeze it really dry before adding to the lasagna.
