How to Make the Recipe
Step 1: Sauté the Mushrooms
In a large skillet, heat 2 tablespoons of olive oil over medium-high heat. Add the sliced cremini mushrooms, season with salt and pepper, and sauté until they release their moisture and become golden brown. Add the garlic and cook for 1 more minute. Remove from heat.
Step 2: Wilt the Spinach
In the same skillet, heat the remaining tablespoon of olive oil. Add the spinach and cook until wilted, about 2–3 minutes. Transfer to a colander and press out excess liquid.
Step 3: Prepare the Cheese Mixture
In a bowl, mix the ricotta, egg, 1 cup of mozzarella, ½ cup Parmesan, and the cooked spinach until well combined.
Step 4: Assemble the Lasagna
Spread ½ cup of marinara sauce in the bottom of a 9×13-inch baking dish. Layer 3 lasagna noodles, half of the ricotta-spinach mixture, half of the mushrooms, a few zucchini planks, and a layer of sauce. Repeat the layers once more. Top with remaining noodles, sauce, mozzarella, and Parmesan.
Step 5: Bake
Cover the dish with foil and bake at 375°F (190°C) for 30 minutes. Remove foil and bake for another 10–15 minutes until bubbly and golden on top.
Step 6: Rest and Garnish
Let the lasagna rest for 10 minutes before slicing. Garnish with chopped fresh basil and/or parsley.
Tips for Making the Recipe
- Slice zucchini uniformly so they cook evenly and lay flat.
- Press moisture out of the spinach to avoid a watery lasagna.
- Let the lasagna rest before serving to help it hold its shape.
- Use high-quality marinara for the best flavor.
- Grate your own mozzarella and Parmesan for better melt and taste.
How to Serve
Serve hot with a fresh green salad, garlic bread, or roasted vegetables for a well-rounded meal. It also pairs well with a glass of red wine or sparkling water with lemon. For added presentation, sprinkle extra herbs or red pepper flakes on top just before serving.
