Step‑by‑Step Instructions for Spinach & Mushroom Lasagna
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This ensures that your Spinach & Mushroom Lasagna bakes evenly and reaches that perfect bubbly golden finish. While the oven warms up, you can prepare your vegetables and cheese mixture, making good use of this time to get everything ready for layering.
Step 2: Sauté the Garlic
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Once the oil is shimmering, add 3 cloves of minced garlic and sauté for about 1-2 minutes, just until fragrant. The aroma will fill your kitchen, signaling that it’s time to move on as the garlic turns light golden—don’t let it burn!
Step 3: Cook the Mushrooms
Next, add 8 ounces of chopped mushrooms to your skillet. Stir them frequently, cooking for about 5-7 minutes until they’re tender and golden brown, releasing their moisture. Once done, remove the skillet from heat and set aside as you prepare the cheese-spinach mixture.
Step 4: Prepare the Cheese Mixture
In a large mixing bowl, combine 15 ounces of ricotta cheese, half of the shredded mozzarella, 3 cups of fresh spinach (washed and chopped), salt, and pepper to taste. Mix well until all ingredients are thoroughly combined, creating a creamy, delicious filling for your Spinach & Mushroom Lasagna.
Step 5: Layer the Ingredients
Start layering in your baking dish by spreading a thin layer of the cheese-spinach mixture across the bottom, creating a soft foundation. Place a single layer of whole wheat lasagna noodles on top, followed by your sautéed mushrooms. Repeat these layers until all ingredients are used, finishing with the cheese mixture.
Step 6: Add Final Toppings
After your layers are complete, sprinkle the remaining mozzarella cheese over the top. Add a generous sprinkle of grated Parmesan cheese to enhance the savory flavor. This will create a beautiful cheesy crown that melts into a delightful topping as the lasagna bakes.
Step 7: Bake the Lasagna
Cover the lasagna with aluminum foil and place it in the preheated oven. Bake for 25 minutes. This steaming process allows the layers to meld together perfectly. After 25 minutes, carefully remove the foil and bake for an additional 15 minutes until the top is bubbly and golden, tempting you to dig in.
Step 8: Let It Rest
Once your Spinach & Mushroom Lasagna is baked to perfection, take it out of the oven and allow it to rest for about 10-15 minutes. This resting period helps the lasagna set, making it easier to slice and serve while preserving those beautiful layers you’ve crafted.

Spinach & Mushroom Lasagna Recipe FAQs
What is the best way to select fresh spinach?
Absolutely! When choosing fresh spinach, look for vibrant, dark green leaves without any yellowing or dark spots. The leaves should feel crisp and firm to the touch—this indicates freshness. If you’re using pre-packaged spinach, check the expiration date and ensure it’s well before that date.
How should I store leftover Spinach & Mushroom Lasagna?
Very good question! Store leftovers in an airtight container in the refrigerator for up to 3 days. Make sure the lasagna has cooled completely before sealing it to help retain its moisture and flavor. If you’re anticipating leftovers beyond that time, freezing is a convenient option!
Can I freeze Spinach & Mushroom Lasagna, and if so, how?
Absolutely, freezing is a great option to enjoy later! To freeze, first, let the lasagna cool completely. Then, wrap it tightly in plastic wrap and cover it with aluminum foil to prevent freezer burn. Label the package with the date, and you can freeze it for up to 3 months. When you’re ready to eat it, thaw it overnight in the fridge, then heat it in the oven at 350°F (175°C) for about 25 minutes, or until warmed through.
What should I do if my lasagna is too watery?
If your Spinach & Mushroom Lasagna turns out watery, it could be due to excess moisture from vegetables like spinach or mushrooms. To fix this before baking, ensure you cook the mushrooms until golden brown and the moisture has evaporated. You can also squeeze out excess water from thawed frozen spinach before mixing it in. Additionally, starting with no-boil lasagna noodles can help absorb some of the moisture as it bakes.
Is this recipe suitable for people with dairy allergies?
If you’re accommodating dairy allergies, I recommend using plant-based alternatives. For instance, replace ricotta with a cashew or tofu-based cheese, and opt for dairy-free mozzarella. There are several delicious brands available, which can help you recreate that creamy texture without the dairy!
