Step‑by‑Step Instructions for Creamy Spinach Mushroom Lasagna
Step 1: Prep Vegetable Filling
Heat a tablespoon of olive oil in a large skillet over medium heat. Sauté sliced mushrooms until golden brown, about 5 minutes. Add chopped fresh spinach and minced garlic, cooking until the spinach is wilted, approximately 2 minutes. Season the filling generously with salt and pepper, then transfer to a bowl to cool while you prepare the béchamel sauce.
Step 2: Make Béchamel Sauce
In a medium saucepan, melt 4 tablespoons of butter over medium heat. Whisk in 1/4 cup of all-purpose flour, stirring constantly to form a roux for about 2 minutes. Gradually pour in 2 cups of warm milk while whisking to keep the sauce smooth. Cook the mixture until it thickens and bubbles, around 5 minutes, then season with ground nutmeg, salt, and pepper.
Step 3: Prepare Lasagna Noodles
If you’re not using no-boil noodles, cook your lasagna sheets in a large pot of boiling salted water according to package instructions. Drain the cooked noodles and lay them flat on a clean kitchen towel to prevent sticking. This step is crucial for ensuring each layer of your Creamy Spinach Mushroom Lasagna is well-structured and easy to assemble.
Step 4: Assemble Lasagna
Preheat your oven to 375°F (190°C). Start by spreading a thin layer of béchamel sauce on the bottom of a 9×13-inch baking dish. Place a layer of lasagna noodles over the sauce, then add 1/3 of the sautéed vegetable filling, dollops of ricotta cheese, and a sprinkle of shredded mozzarella. Repeat this layering process two more times, finishing with noodles on top.
Step 5: Final Layer and Bake
Once assembled, pour any remaining béchamel sauce over the top layer of noodles and scatter the remaining mozzarella and grated Parmesan cheese across the surface. Cover the dish with aluminum foil and bake for 25 minutes. Remove the foil and bake for an additional 15 minutes until the cheese is golden brown and bubbling, achieving that perfect melted texture.
Step 6: Rest Before Serving
After removing the lasagna from the oven, let it rest for 10 minutes before slicing. This resting period allows the layers to set, making it easier to serve neat portions of your Creamy Spinach Mushroom Lasagna. Enjoy the delightful aroma and flavors as you savor each bite!
How to Store and Freeze Creamy Spinach Mushroom Lasagna
Fridge: Store any leftovers in an airtight container for up to 3 days. Reheat in the microwave or oven to keep its creamy texture.
Freezer: For longer storage, freeze the lasagna before baking—just cover tightly with plastic wrap and foil. It keeps well for up to 3 months.
Reheating: To reheat, thaw overnight in the fridge if frozen. Bake covered with foil at 350°F (175°C) for about 30-40 minutes until heated through, keeping that creamy spinach mushroom lasagna delightful and moist.
Make-Ahead: You can prepare the lasagna and refrigerate it unbaked for up to 24 hours. Just be aware that it may require extra baking time if chilled.
Expert Tips for Creamy Spinach Mushroom Lasagna
- Prep Ahead: Assemble your lasagna a day in advance and refrigerate. Just be sure to bake it longer if chilled to ensure it’s heated through.
- Layer Smart: Make sure to spread béchamel sauce evenly between layers to prevent dryness—this ensures each bite of your creamy spinach mushroom lasagna is luxurious.
- Vegetable Variations: Don’t hesitate to add different veggies like zucchini or bell peppers; just be sure to chop them finely to ensure even cooking and a balanced flavor profile.
- Avoid Soggy Noodles: If you’re using regular lasagna noodles, avoid overcooking them. They should be slightly firm, as they’ll absorb moisture during baking.
- Rest Time: Let the lasagna sit for at least 10 minutes after baking. This helps the layers set, making it easier to serve without falling apart.
Make Ahead Options
These Easy Creamy Spinach Mushroom Lasagna layers can easily be prepped in advance, making them perfect for meal prep enthusiasts! You can assemble the entire lasagna up to 24 hours ahead of time and refrigerate it, which preserves the flavors and keeps the dish just as delicious. To maintain the quality, cover the assembled lasagna tightly with foil or plastic wrap. When you’re ready to bake, simply add 5-10 extra minutes to the oven time if it’s coming straight from the refrigerator. Alternatively, you can freeze the unbaked lasagna for up to 3 months. Just be sure to let it thaw overnight in the fridge before baking for the best results! Enjoy the ease of having your Creamy Spinach Mushroom Lasagna ready and waiting for a busy weeknight dinner!

Creamy Spinach Mushroom Lasagna Recipe FAQs
How do I choose the right spinach for my lasagna?
Absolutely! When selecting fresh spinach, look for vibrant green leaves that are crisp and free from dark spots or yellowing. Baby spinach is particularly tender and sweet; however, mature spinach can work too as long as it’s fresh! If you’re preparing a large batch ahead, you might consider kale or Swiss chard as a fantastic substitute for a different twist.
What is the best way to store leftover lasagna?
Very! Store any leftover Creamy Spinach Mushroom Lasagna in an airtight container and keep it in the refrigerator for up to 3 days. Just reheat slices in the microwave or oven, keeping them covered to retain moisture, ensuring each bite is still creamy and delicious!
Can I freeze lasagna, and how?
Absolutely! To freeze your lasagna, assemble it in your baking dish without baking it first. Cover it tightly with plastic wrap and then a layer of aluminum foil to prevent freezer burn. It can stay frozen for up to 3 months. When ready to enjoy, thaw in the refrigerator overnight and bake as directed; just add a little extra time if it’s still cold from the fridge.
What should I do if my béchamel sauce is too thick?
If your béchamel sauce turns out too thick, don’t worry! Just whisk in a bit more warm milk, a little at a time, until you reach your desired consistency. It’s essential to stir continuously to maintain a smooth sauce. If it’s too runny, let it simmer on low heat, stirring often until it thickens to your preference.
Can this recipe be made gluten-free?
Very much so! To make your Creamy Spinach Mushroom Lasagna gluten-free, substitute the all-purpose flour with a gluten-free flour blend when making your béchamel sauce and use gluten-free lasagna noodles. It’s a wonderful way to enjoy all the creamy goodness without the gluten!
Are there any vegan-friendly alternatives I can use?
Certainly! For a vegan version, replace dairy ingredients with plant-based substitutes: use almond or oat milk for the béchamel, a vegan butter option, and try a mix of tofu blended with nutritional yeast in place of ricotta. Vegan cheese is a great swap for mozzarella and Parmesan, ensuring every layer is deliciously satisfying!
