Ingredients

• 1 medium (about 1 lb), sliced into 1/4-inch rounds eggplant
• 2 medium, sliced into 1/4-inch rounds zucchini
• 4 cups fresh spinach
• 1 cup ricotta cheese
• 1 1/2 cups mozzarella cheese shredded
• 1/2 cup Parmesan cheese grated
• 2 cups marinara sauce
• 3 tbsp olive oil
• 3 cloves garlic cloves minced
• 1 tsp dried oregano
• 1 tsp salt
• 1/2 tsp black pepper

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 1 minute until fragrant. Add 4 cups fresh spinach and cook until wilted, about 3 minutes. Season with 1/2 tsp salt and 1/4 tsp black pepper. Remove from heat.
2. Step 2: Brush both sides of 1 medium eggplant sliced into 1/4-inch rounds and 2 medium zucchini sliced into 1/4-inch rounds with 1 tbsp olive oil. Arrange on a baking sheet and roast in the oven for 10 minutes until edges are tender and slightly browned.
3. Step 3: In a 9x13 inch baking dish, spread 1/2 cup marinara sauce evenly. Layer half the roasted eggplant slices, then half the zucchini slices, followed by half the cooked spinach, 1/2 cup ricotta cheese, 1/2 cup shredded mozzarella, and 1/4 cup grated Parmesan. Sprinkle 1/2 tsp dried oregano, 1/2 tsp salt, and 1/4 tsp black pepper over the layers.
4. Step 4: Repeat layering with remaining vegetables, ricotta, mozzarella, Parmesan, and sauce. Finish with remaining 1 cup marinara sauce on top.
5. Step 5: Cover with foil and bake for 30 minutes. Remove foil and bake an additional 10 minutes until cheese is bubbly and golden. Let rest for 10 minutes before slicing and serving.
