Step‑by‑Step Instructions for Mushroom And Spinach Lasagna
Step 1: Preheat Oven and Prepare Dish
Begin by preheating your oven to 375°F (190°C). While the oven is heating, grease a 9×13-inch baking dish with a little olive oil to prevent sticking. This simple step sets the stage for your creamy Mushroom And Spinach Lasagna and ensures it comes out perfectly golden and bubbly.
Step 2: Cook Lasagna Noodles
Bring a large pot of salted water to a boil. Once the water is boiling, carefully add the lasagna noodles and cook them until al dente, usually around 8–10 minutes. Drain the noodles and set them aside, ensuring they don’t stick together. This is crucial for achieving the right texture in your lasagna.
Step 3: Sauté Onions and Garlic
In a large skillet, heat a couple of tablespoons of olive oil over medium heat. Add the chopped onion and sauté for 3–4 minutes until they turn translucent. Then, add the minced garlic and cook for an additional minute, stirring frequently to release its fragrant aroma—this step enhances the overall flavor of the Mushroom And Spinach Lasagna.
Step 4: Add Mushrooms and Spinach
Stir in the sliced mushrooms along with the dried thyme, salt, and pepper to taste. Cook the mixture for about 5–7 minutes, until the mushrooms are tender and their liquid has evaporated. Next, add the fresh spinach and cook briefly until wilted; this adds a vibrant color and fresh taste to your lasagna filling.
Step 5: Start Layering the Lasagna
Spread a thin layer of marinara sauce at the bottom of your greased baking dish. Then, place three lasagna noodles over the sauce, slightly overlapping them. This forms the first layer of your Mushroom And Spinach Lasagna. Make sure the noodles are evenly spaced for even cooking.
Step 6: Fill the Lasagna Layers
Spread half of the ricotta cheese evenly over the noodles, followed by half of the mushroom and spinach mixture. Sprinkle one-third of the mozzarella and Parmesan cheeses over this layer. Each layer of filling contributes to the deliciously rich taste, so take your time to spread everything out nicely.
Step 7: Repeat the Layers
Continue with the layering process by adding another three lasagna noodles on top, followed by the remaining ricotta, the rest of the mushroom mixture, and yet another sprinkle of mozzarella and Parmesan. This repetition builds a hearty, comforting Mushroom And Spinach Lasagna that everyone will love.
Step 8: Finish with Sauce and Cheese
Pour the remaining marinara sauce over the final layer of cheese, ensuring it is evenly distributed. Top with the last bits of mozzarella and Parmesan cheese. This top layer will create a golden, melty crust as it bakes—so make sure it’s generous!
Step 9: Bake the Lasagna
Cover the baking dish tightly with aluminum foil to keep the moisture in while baking. Place it in the preheated oven and bake for 25 minutes. After that, remove the foil and continue baking for another 10–15 minutes until the cheese is bubbly and golden brown. This step is crucial for achieving that perfect lasagna finish.
Step 10: Cool and Serve
Once your Mushroom And Spinach Lasagna is done baking, allow it to cool for about 10 minutes before slicing. This helps it set and makes serving easier. Garnish with fresh basil if desired, then slice and serve warm, inviting your family to enjoy this comforting dish around the table.

Mushroom And Spinach Lasagna Recipe FAQs
How do I choose the right mushrooms for the Mushroom and Spinach Lasagna?
Absolutely! When selecting mushrooms, aim for fresh, firm ones free of dark spots. Varieties like cremini or button mushrooms are excellent, but feel free to experiment with others like portobello for a meatier texture. Just ensure they are dry and have a pleasant aroma for the best flavor in your lasagna.
How should I store leftover Mushroom and Spinach Lasagna?
Store any leftovers in an airtight container in the fridge, and they will keep well for up to 3 days. Reheat in the oven at 350°F (175°C) until we’re talking about warmed through and enticing aromas filling the air again.
Can I freeze Mushroom and Spinach Lasagna?

When it’s time to enjoy it, simply defrost overnight in the refrigerator and bake as directed, with an added 10–15 minutes of time if frozen when going into the oven.
What should I do if my lasagna turns out watery?
Often, watery lasagna stems from excess sauce or not properly draining the spinach if you use frozen. To fix it, layer your ingredients carefully, keeping sauce to a moderate amount.
