Introduction
Spinach Mushroom White Lasagna is a creamy, comforting baked pasta dish layered with tender spinach, savory mushrooms, silky white sauce, and plenty of melted cheese. The combination of earthy mushrooms, fresh greens, garlic, and creamy cheese creates a rich vegetarian lasagna that’s perfect for family dinners and special gatherings.
Origin
This recipe is inspired by traditional Italian lasagna while replacing the classic tomato-based sauce with a creamy white sauce. Spinach, mushrooms, Parmesan, and mozzarella add a flavorful combination commonly found in Italian-inspired vegetarian cooking.
Cultural Significance
Lasagna is one of the most recognizable Italian comfort foods, known for its layered pasta, sauce, cheese, and flavorful fillings. White lasagna offers a popular variation by using a creamy béchamel-style sauce instead of tomato sauce, while vegetables make it hearty without requiring meat.

Tips for Success
Slice the mushrooms evenly so they cook at the same rate.
Cook the mushrooms until their excess moisture evaporates. This prevents watery lasagna.
Don’t skip sautéing the spinach before layering because excess moisture can make the finished dish soggy.
Use freshly grated Parmesan for a smoother white sauce.
Allow the lasagna to rest after baking so the layers can set before slicing.
Cover the lasagna during the first portion of baking to prevent the cheese from browning too quickly.
Instructions
Step 1 Prepare the Oven
Preheat the oven to 375°F (190°C).
Lightly grease a 9 × 13-inch baking dish.
Step 2 Sauté the Mushrooms
Heat the olive oil in a large skillet over medium-high heat.
Add the sliced mushrooms.
Cook for approximately 7–9 minutes, stirring occasionally, until the mushrooms are golden brown and most of their moisture has evaporated.
Season with Italian seasoning, salt, and black pepper.
Step 3 Add the Spinach
Add the fresh spinach to the skillet.
Cook for approximately 2–3 minutes, stirring frequently, until the spinach wilts.
Remove from the heat and set aside.
Step 4 Prepare the White Sauce
Melt the butter in a large saucepan over medium heat.
Add the diced onion or shallot.
Cook for approximately 3–4 minutes, until softened.
Add the minced garlic and cook for another 30–60 seconds.
Stir in the flour and cook for approximately 1 minute, stirring constantly.
Step 5 Add the Milk and Cream
Gradually whisk in the whole milk.
Add the heavy cream.
Continue whisking until smooth.
Cook for approximately 5–7 minutes, stirring frequently, until the sauce thickens.
Season with kosher salt, black pepper, and nutmeg.
Step 6 Add the Parmesan
Reduce the heat to low.
Gradually stir in the Parmesan cheese.
Continue stirring until the cheese melts and the sauce becomes smooth and creamy.
Remove from the heat.
Step 7 Cook 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 carefully and arrange the noodles separately to prevent sticking.
Step 8 Prepare the Ricotta
Place the ricotta cheese in a bowl.
Stir until smooth.
For extra flavor, mix in ¼ cup of the prepared white sauce and 2 tablespoons of chopped parsley.
Step 9 Assemble the Lasagna
Spread a thin layer of white sauce across the bottom of the baking dish.
Place a layer of lasagna noodles over the sauce.
Spread approximately one-third of the ricotta mixture over the noodles.
Add one-third of the spinach and mushroom mixture.
Spoon white sauce over the vegetables.
Sprinkle with mozzarella and Parmesan.
Repeat the layers until the ingredients are used.
Finish with a final layer of noodles, white sauce, mozzarella, and Parmesan.
Step 10 Bake
Cover the baking dish loosely with aluminum foil.
Bake for approximately 30 minutes.
Remove the foil and continue baking for another 15–20 minutes, until the cheese is melted, bubbling, and lightly golden.
For a deeper golden top, broil for 1–2 minutes, watching carefully.
Step 11 Rest
Remove the lasagna from the oven.
Allow it to rest for 10–15 minutes before slicing.
Step 12 Serve
Garnish with fresh parsley, basil, Parmesan, or freshly cracked black pepper.
Serve warm.
