There’s something so comforting about lasagna, especially when it’s packed with tender spinach, savory mushrooms, creamy béchamel, and loads of melty cheese.

This version skips the red sauce but doubles down on richness and flavor.
Perfect for cozy nights or a meatless dinner that still feels indulgent.

What You’ll Need (Ingredient Highlights)
Lasagna noodles – Pre-cooked or oven-ready work great.
Spinach – Use fresh or frozen—both add vibrant green flavor.
Mushrooms – Cremini or button mushrooms bring depth and umami.
Garlic + olive oil – Simple aromatics for the veggie layer.
Béchamel sauce – A rich white sauce made from butter, flour, and milk.
Ricotta, mozzarella, and Parmesan – Creamy, melty, and golden on top.
Nutmeg – Optional, but adds a warm, subtle note to the sauce.
Fresh parsley – For garnish and color at the end.
Pro Tips Before You Start
Sauté mushrooms until golden for best flavor. Don’t rush this step.
Use oven-ready noodles to skip boiling—or pre-cook if using regular noodles.
Whisk béchamel constantly to prevent lumps.
Let lasagna rest after baking—it sets and slices more cleanly.
Fresh spinach works great, but frozen is super convenient.
How to Make Spinach Mushroom White Lasagna
Step 1: Preheat and Prep
Preheat oven to 375°F (190°C).
Grease a 9×13-inch baking dish with oil or butter.
Step 2: Cook the Vegetables
In a large skillet, heat olive oil over medium.
Add minced garlic and sliced mushrooms.
Sauté for 5–7 minutes, until mushrooms are browned and tender.
Add spinach, and cook until wilted (or heated through if using frozen).
Season with salt and pepper, then set aside.
Step 3: Make the Béchamel Sauce
In a saucepan, melt butter over medium heat.
Whisk in flour and cook for 1–2 minutes until light golden.
Gradually add milk, whisking constantly until smooth.
Bring to a simmer and cook for 5–7 minutes, until thickened.
Season with salt, pepper, and a pinch of nutmeg if using.
Step 4: Assemble the Lasagna
Spread a thin layer of béchamel on the bottom of the baking dish.
Lay down a layer of lasagna noodles.
Top with part of the spinach and mushroom mixture, dollops of ricotta, and a sprinkle of mozzarella and Parmesan.
Repeat the layers: noodles → veggies → cheeses → béchamel.
End with a final layer of noodles, béchamel, and the remaining mozzarella and Parmesan on top.
Step 5: Bake
Cover the dish with foil and bake for 25 minutes.
Remove foil and bake uncovered for an additional 10–15 minutes, until the top is golden and bubbly.
Step 6: Rest and Serve
Let the lasagna rest for 10 minutes before slicing.
Garnish with fresh parsley, if desired.
Serve warm and cheesy!
