Step‑by‑Step Instructions for Mushroom And Spinach Lasagna
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This ensures the perfect baking temperature for your Mushroom and Spinach Lasagna. Preheating will help achieve that bubbly, golden top that everyone looks forward to. While the oven warms up, you can prepare your baking dish and gathering the rest of your ingredients.
Step 2: Prepare the Baking Dish
Take a 9×13-inch baking dish and grease it generously with olive oil or cooking spray. This is an essential step to prevent the lasagna from sticking and makes for easier serving later. Ensure every corner is coated well, and set the dish aside as you move on to cooking the noodles.
Step 3: Cook the Lasagna Noodles
Bring a large pot of salted water to a boil and cook the lasagna noodles according to package instructions until they are al dente, which usually takes about 8-10 minutes. Drain the noodles well and set them aside on a clean kitchen towel or a lightly oiled surface to prevent sticking as you prepare the filling.
Step 4: Sauté the Vegetables
In a large skillet, heat a tablespoon of olive oil over medium heat. Add finely chopped onion and sauté for 3-4 minutes until it becomes translucent. Stir in the minced garlic and sliced mushrooms, cooking until the mushrooms are tender and their liquid has evaporated, about 5-7 minutes. Finally, add the spinach and cook until wilted, around 2-3 minutes, creating a flavorful filling for your lasagna.
Step 5: Assemble the Lasagna
Spread a layer of marinara sauce evenly across the bottom of your prepared baking dish. Next, place three lasagna noodles over the sauce. Then, layer half of the ricotta cheese, followed by the mushroom and spinach mixture, and sprinkle one-third of the mozzarella and Parmesan cheese on top. Repeat the layers, finishing with a final layer of noodles topped generously with marinara sauce.
Step 6: Bake the Lasagna
Cover the assembled Mushroom and Spinach Lasagna with aluminum foil and place it in the preheated oven. Bake for 25 minutes to allow the flavors to meld beautifully. After 25 minutes, carefully remove the foil to reveal a tantalizing sight, and continue baking for another 10-15 minutes until the cheese is bubbly and golden brown.
Step 7: Cool and Serve
Once baked, remove the lasagna from the oven and let it cool for about 10 minutes before slicing. This waiting time helps the layers set a bit, making it easier to serve. If desired, garnish with freshly chopped basil to add a burst of freshness and color before enjoying your delicious Mushroom and Spinach Lasagna!
