Step‑by‑Step Instructions for Mushroom and Spinach Lasagna
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). While the oven warms up, grease a 9×13-inch baking dish with a light coating of olive oil or cooking spray. This will prevent your delicious Mushroom and Spinach Lasagna from sticking, ensuring easy removal after baking.
Step 2: Cook the Lasagna Noodles
In a large pot, bring salted water to a rolling boil. Add the lasagna noodles and cook according to the package instructions until al dente, usually about 8-10 minutes. Stir occasionally to prevent sticking. Once cooked, drain the noodles in a colander and rinse them briefly with cold water to stop cooking, setting them aside for later.
Step 3: Prepare the Filling
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the chopped onion, sautéing for 3-4 minutes or until translucent. Toss in minced garlic and cook for an additional minute, just until fragrant. Next, add the sliced mushrooms, dried thyme, salt, and pepper, sautéing until the mushrooms are tender and moisture evaporates. Finally, stir in the fresh spinach and wilt it for about 2 minutes before removing the skillet from the heat.
Step 4: Assemble the Lasagna
Spread a layer of marinara sauce on the bottom of your greased baking dish. Place a layer of lasagna noodles over the sauce, followed by dollops of ricotta cheese, the sautéed mushroom and spinach filling, and a sprinkle of mozzarella and parmesan. Repeat the layers until all ingredients are used, finishing with a final layer of noodles topped with marinara sauce and the remaining mozzarella and parmesan cheese.
Step 5: Bake the Lasagna
Cover the assembled Mushroom and Spinach Lasagna with aluminum foil and bake in the preheated oven for 25 minutes. After this time, carefully remove the foil to reveal the bubbling layers beneath. Continue baking for another 10-15 minutes, or until the cheese is melted, bubbly, and golden brown, creating a deliciously inviting top.
Step 6: Serve and Garnish
Once baked, remove the lasagna from the oven and allow it to cool for about 10 minutes. This rest time helps the layers set, making it easier to slice. Garnish the top with fresh basil leaves for an aromatic touch before serving warm to your guests.

Mushroom and Spinach Lasagna Recipe FAQs
How do I select the right mushrooms for my lasagna?
Absolutely! When choosing mushrooms, look for firm, plump ones without dark spots or blemishes. Varieties like cremini or button mushrooms work best for their rich flavor. If you find some that are wrinkled or slimy, it’s best to avoid those as they might be past their prime.
How should I store my Mushroom and Spinach Lasagna?
Leftovers should be stored in an airtight container in the refrigerator for up to 4 days. Just make sure it’s cooled to room temperature before sealing. If you’re aiming to keep it longer, consider freezing; it can last up to 3 months when wrapped tightly.
Can I freeze the Mushroom and Spinach Lasagna?
Of course! To freeze, wrap the assembled lasagna tightly in plastic wrap followed by aluminum foil. This double layer will help prevent freezer burn. You can bake it from frozen, just add about 20 to 30 minutes more to the baking time, or thaw it overnight in the fridge before baking.
What can I do if my lasagna noodles stick together?
Very! It’s common for noodles to stick if they’re not monitored while cooking. Stir the noodles occasionally while they’re boiling, and after draining, rinse them with cold water to stop the cooking. This will help separate them and make assembly easier!
Are there any dietary considerations I should keep in mind?
Absolutely! If you’re cooking for someone with a dairy allergy, you can substitute ricotta and mozzarella with dairy-free alternatives. Additionally, always ensure that your marinara sauce and lasagna noodles are labeled gluten-free if needed. If you have pets, be aware that some ingredients like onions and garlic can be toxic to dogs, so serve them a pet-friendly meal instead.
What if I want to make my lasagna ahead of time?
The more the merrier! You can assemble your Mushroom and Spinach Lasagna a day in advance. Just cover it tightly and keep it in the refrigerator.
