- Boil the noodles: If you’re not using oven-ready noodles, cook them until al dente and lay them flat on parchment to prevent sticking.
- Layer the lasagna: Start with béchamel on the bottom, then noodles, sautéed veggies, more béchamel, and cheese. Repeat layers until the top.
- Bake: Cover with foil and bake at 375°F for 25 minutes. Uncover and bake another 15 minutes until golden and bubbly.

Easy Tweaks for the Perfect Creamy Spinach Mushroom Lasagna
Making a memorable creamy spinach mushroom lasagna doesn’t mean sticking to rigid rules. There’s plenty of room for substitutions and upgrades, especially if you’re working with what’s in your fridge or pantry.

Want to add a boost of protein? A layer of cooked lentils blends seamlessly into the sauce while keeping it vegetarian.
As for cheese, while mozzarella and parmesan are classic, a spoonful of ricotta adds creaminess between the layers. If you’re wondering whether to use ricotta or béchamel, the answer is: why not both? They complement each other beautifully. For a vegan twist, opt for dairy-free cheeses and use plant-based milk for the sauce.
