Ingredients

For the Lasagna

• 12 lasagna noodles
• 2 tablespoons olive oil
• 1 medium onion, finely chopped
• 4 cloves garlic, minced
• 16 ounces mushrooms, sliced (cremini or button mushrooms work well)
• 5 cups fresh spinach
• 15 ounces ricotta cheese
• 1 large egg
• 1 cup grated parmesan cheese
• 2 cups shredded mozzarella cheese
• ½ teaspoon salt
• ½ teaspoon black pepper
• ¼ teaspoon nutmeg (optional but recommended)

For the Creamy White Sauce

• 4 tablespoons unsalted butter
• 4 tablespoons all-purpose flour
• 3 cups whole milk
• 1 teaspoon garlic powder
• ½ teaspoon salt
• ½ teaspoon black pepper
• ¼ teaspoon nutmeg
• ½ cup grated parmesan cheese

Instructions

1. Prepare the lasagna noodles

Bring a large pot of salted water to a boil. Cook the lasagna noodles according to the package directions until al dente. Drain and lay them flat on parchment paper to prevent sticking.

2. Cook the mushroom spinach filling

Heat olive oil in a large skillet over medium heat. Add the chopped onion and cook for 3–4 minutes until softened.

Stir in the minced garlic and cook for another minute until fragrant.

Add the sliced mushrooms and cook for about 6–8 minutes until they release their moisture and begin to brown.

Add the fresh spinach and cook until wilted, about 2 minutes. Remove from heat and allow the mixture to cool slightly.

3. Prepare the ricotta mixture

In a mixing bowl, combine ricotta cheese, egg, ½ cup parmesan cheese, salt, pepper, and nutmeg.

Stir until smooth and well blended.

Fold the mushroom and spinach mixture into the ricotta mixture until evenly distributed.

4. Make the creamy white sauce

In a saucepan, melt butter over medium heat.

Whisk in the flour and cook for about 1 minute, stirring constantly to form a smooth roux.

Gradually pour in the milk while whisking to prevent lumps.

Continue cooking for 4–5 minutes until the sauce thickens.

Stir in garlic powder, salt, pepper, nutmeg, and parmesan cheese. Remove from heat once the sauce becomes smooth and creamy.

5. Preheat the oven

Preheat your oven to 375°F (190°C).

Lightly grease a 9×13-inch baking dish.

6. Assemble the lasagna

Spread a thin layer of white sauce on the bottom of the baking dish.

Add a layer of lasagna noodles.

Spread one-third of the ricotta mushroom mixture over the noodles.

Drizzle white sauce over the filling and sprinkle with mozzarella.

Repeat the layers two more times.

Finish with remaining white sauce and a generous layer of mozzarella and parmesan cheese on top.

7. Bake the lasagna

Cover the dish with foil and bake for 25 minutes.

Remove the foil and bake for another 20 minutes until the top is golden and bubbly.

8. Rest before serving

Allow the lasagna to rest for 10–15 minutes before slicing. This helps the layers set and makes serving easier.

Expert Tips for Perfect White Lasagna

Use a mix of mushrooms

Combining cremini, shiitake, or portobello mushrooms creates deeper flavor than using only one type.

Sauté mushrooms properly

Cook mushrooms long enough so their moisture evaporates. This prevents a watery lasagna.

Season each layer

Light seasoning throughout the layers ensures balanced flavor.

Let it rest before cutting

This is one of the most important steps for clean slices and proper texture.

Delicious Variations

This recipe is incredibly versatile. Here are some tasty ways to customize it.

Chicken Mushroom White Lasagna

Add shredded rotisserie chicken between the layers for a protein boost.

Spinach Artichoke Lasagna

Mix chopped marinated artichokes into the ricotta mixture.

Roasted Vegetable Lasagna

Include roasted zucchini, bell peppers, or eggplant.

Gluten-Free Version

Simply use gluten-free lasagna noodles and substitute gluten-free flour for the sauce.

Extra Cheesy Lasagna

Add provolone, fontina, or gouda cheese for even richer flavor.

What Makes White Lasagna Different?

Traditional lasagna relies on tomato sauce, but white lasagna focuses on creamy sauces and cheeses. The result is a richer, silkier texture and a slightly more delicate flavor profile.

This variation is particularly popular in vegetarian recipes because the creamy sauce pairs beautifully with vegetables like mushrooms, spinach, and zucchini.

The result feels indulgent while still highlighting fresh ingredients.

Serving Suggestions

This creamy lasagna pairs wonderfully with simple sides that balance its richness.

Fresh Green Salad

A crisp salad with lemon vinaigrette cuts through the creamy texture.

Garlic Bread

Warm garlic bread is perfect for soaking up extra sauce.

Roasted Vegetables

Roasted asparagus or broccoli complements the dish beautifully.

Light Soup Starter

A small bowl of vegetable soup or tomato soup makes a complete meal.

Make-Ahead and Storage Tips

Make Ahead

You can assemble the entire lasagna up to 24 hours in advance and refrigerate it before baking.

Freezing

Lasagna freezes exceptionally well.

Wrap tightly and freeze for up to 3 months.

To bake from frozen, cover with foil and bake at 350°F for about 60–75 minutes.

Leftovers

Store leftovers in an airtight container in the refrigerator for 3–4 days.

Reheat individual portions in the microwave or oven.

Fun Food Fact

Lasagna is believed to date back to ancient Rome, where early versions used layers of pasta sheets and sauces. Over time, the dish evolved into the rich baked casserole we know today.
