Instructions

  1. Step 1: Preheat oven to 375°F. Heat 2 tbsp olive oil in a large skillet over medium heat. Add 3 minced garlic cloves and sauté for 30 seconds until fragrant. Add 12 oz sliced white mushrooms and cook for 5-6 minutes until browned and their moisture evaporates.
  2. Step 2: Add 5 cups roughly chopped fresh spinach to the skillet with mushrooms, stirring until wilted, about 2-3 minutes. Season with 1 tsp salt, 1/2 tsp black pepper, and 1 tsp dried oregano. Remove from heat.
  3. Step 3: In a 9x13 baking dish, spread 1/2 cup marinara sauce evenly on the bottom. Layer 3 cooked lasagna noodles on top, then spread 1/2 of the ricotta cheese (3/4 cup), half the mushroom-spinach mixture, 1 cup shredded mozzarella cheese, and 1 cup marinara sauce.
  4. Step 4: Repeat layering with 3 noodles, remaining ricotta, mushroom-spinach mixture, 1 cup mozzarella, and 1 cup marinara. Top with last 3 noodles, remaining marinara sauce, 1/2 cup mozzarella, and sprinkle 1/2 cup grated Parmesan cheese.
  5. Step 5: Cover with foil and bake for 25 minutes. Remove foil and bake for an additional 15 minutes until bubbly and golden on top. Let rest for 10 minutes before serving.
