Step‑by‑Step Instructions for Creamy Spinach Mushroom Lasagna
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This ensures that your Creamy Spinach Mushroom Lasagna bakes evenly and develops a perfectly golden top. While the oven is heating, gather your ingredients and prepare your workspace to make the cooking process smoother and more enjoyable.
Step 2: Cook Lasagna Noodles
In a large pot, bring water to a boil and add a sprinkle of salt. Cook the 12 lasagna noodles according to the package instructions until they are al dente, typically around 8-10 minutes. Once done, drain the noodles and lay them flat on a clean surface or a lightly greased baking sheet to prevent sticking.
Step 3: Sauté Vegetables
Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add 1 small diced onion and sauté for about 5 minutes, or until it turns translucent. Then, stir in 4 minced garlic cloves and 8 ounces of sliced mushrooms, cooking for an additional 5-7 minutes until the mushrooms are browned and their moisture has evaporated, creating a savory base for your lasagna.
Step 4: Add Spinach and Seasoning
With the mushrooms cooked, add 4 cups of fresh spinach to the skillet (or 2 cups of thawed frozen spinach). Cook until the spinach has wilted down, about 2-3 minutes. Season your filling with 1 teaspoon each of dried oregano and basil, along with salt and pepper to taste. If using, sprinkle in ¼ teaspoon of nutmeg for added warmth. Remove the skillet from heat and set aside.
Step 5: Prepare Cheese Mixture
In a mixing bowl, combine 2 cups of ricotta cheese, 1 egg, 1 cup of shredded mozzarella cheese, and half of the grated Parmesan cheese. Stir together until the mixture is smooth and well blended. This creamy filling will be the heart of your Creamy Spinach Mushroom Lasagna, providing richness and flavor.
Step 6: Assemble the Lasagna
Spread a thin layer of marinara sauce (about ½ cup) at the bottom of a 9x13 inch baking dish, creating a moist base. Layer 4 lasagna noodles over the sauce. Next, spoon half of the ricotta cheese mixture evenly over the noodles, followed by half of the spinach-mushroom mixture and a third of the remaining marinara sauce. Repeat this layering process once more.
Step 7: Final Layer and Bake
Finish by layering the last 4 lasagna noodles on the top. Spread the remaining marinara sauce over these noodles, then sprinkle the last cup of shredded mozzarella and remaining grated Parmesan cheese on top. Cover the dish with aluminum foil, being careful not to touch the cheese, to ensure it stays moist and cooks properly.
Step 8: Bake the Lasagna
Place the lasagna in the preheated oven and bake covered for 25 minutes. This initial baking phase allows the flavors to meld beautifully. After 25 minutes, carefully remove the foil and bake for an additional 15 minutes. Look for the cheese to be bubbly and golden brown, indicating your Creamy Spinach Mushroom Lasagna is ready.
Step 9: Rest and Serve
Once baked, remove the lasagna from the oven and let it cool for about 10-15 minutes. This resting period allows the layers to set, making for easier slicing. After resting, cut into squares and serve, enjoying the delicious combination of flavors that make this dish a standout.

Make Ahead Options
These Creamy Spinach Mushroom Lasagna are perfect for busy home cooks looking to save time during the week! You can prepare the entire lasagna up to 24 hours in advance, ensuring it’s ready to pop in the oven whenever you need a comforting meal. Simply assemble the lasagna but hold off on baking it; cover it tightly with aluminum foil and refrigerate. To maintain its delicious quality, consider adding an extra five minutes of baking time if it's coming straight from the fridge to the oven. When you're ready to serve, just bake at 375°F (190°C) until bubbly and golden, and enjoy a hearty, homemade dinner with minimal effort!
Expert Tips for Creamy Spinach Mushroom Lasagna

Cool Before Cutting: Allow the lasagna to rest for 10-15 minutes after baking. This helps the layers set for clean, beautiful slices.
