Wholesome Ingredients for This Cheesy Spinach Zucchini Lasagna

Each ingredient in this easy spinach zucchini lasagna recipe is carefully chosen to enhance its flavor and nutritional profile. Let’s highlight a few key players:

• Spinach: Packed with iron, vitamin K, and antioxidants, spinach is a nutrient powerhouse. For convenience, you can use frozen spinach but make sure to thaw and drain thoroughly.
• Zucchini: With its mild flavor and high water content, zucchini provides a low-carb alternative to traditional pasta layers. Pro tip: slice your zucchini evenly for consistent cooking.
• Ricotta Cheese: Creamy with a naturally lighter texture, part-skim ricotta offers protein while keeping fats in check. For a dairy-free option, try a tofu-based ricotta substitute.

How to Make Cheesy Spinach Zucchini Lasagna

1. Preheat your oven to 375°F and coat a 9×13-inch baking dish with cooking spray.
2. Heat 2 tablespoons of olive oil in a skillet over medium-high heat. Sauté the mushrooms, garlic, salt, and pepper until tender and golden, about 6-8 minutes. Set aside.
3. Using the same skillet, heat the remaining oil and cook the spinach in batches, stirring until wilted. Press out excess water and cook for an additional 3 minutes to reduce moisture. Remove from heat.
4. Combine the egg, ricotta, 1 cup mozzarella, and ½ cup Parmesan in a mixing bowl. In a separate bowl, mix the remaining mozzarella and Parmesan for topping.
5. Spread 1 cup marinara sauce at the base of the prepared dish. Layer 3 noodles on top, followed by half the ricotta mixture. Add the mushrooms and spinach evenly. Spread another cup of sauce.
6. Repeat the layers with the remaining noodles, ricotta mixture, and zucchini slices. Finish with the remaining marinara sauce and mozzarella-Parmesan topping for the ultimate cheesy crust.
7. Bake until bubbly with lightly browned cheese, about 45 minutes. Let cool for 10 minutes before slicing. Garnish with basil or parsley, if desired.
