Ingredients
Method
- Preheat oven to 375°F (190°C). Cook lasagna noodles according to package directions. Drain and set aside.
- Heat olive oil in a skillet over medium heat. Saute zucchini, mushrooms, bell pepper, and garlic until tender, about 7 minutes. Add spinach and cook until wilted. Season with salt, pepper, and Italian seasoning.
- In a bowl, mix ricotta cheese with egg, salt, and pepper until smooth.
- Spread 1/2 cup marinara on the bottom of a 9x13 baking dish. Layer 4 noodles, half the ricotta mixture, half the sauteed vegetables, 1 cup marinara, and 2/3 cup mozzarella. Repeat layers. Top with remaining noodles, marinara, mozzarella, and Parmesan.
- Cover with foil and bake for 25 minutes. Remove foil and bake another 15-20 minutes until bubbly and golden. Let rest 10 minutes before slicing.
Notes
You can assemble this lasagna a day ahead and refrigerate. Add 10 minutes to bake time if going straight from the fridge. Swap any vegetables you like—broccoli, kale, and roasted red peppers all work great.
