Description

Spinach and Mushroom White Lasagna is a creamy, cheesy vegetarian twist on classic lasagna. Made with tender noodles, garlicky mushrooms, wilted spinach, and a rich white béchamel sauce, this dish is perfect for cozy dinners or elegant gatherings. It’s a hearty meatless main that’s flavorful, easy to make, and perfect for make-ahead meals.


Ingredients

  • For the Filling:
  • Olive oil or butter
  • Fresh mushrooms (sliced)
  • Fresh spinach (or frozen, thawed and squeezed dry)
  • Garlic (minced)
  • Salt and pepper
  • Ricotta cheese
  • Egg
  • Shredded mozzarella cheese
  • Grated Parmesan cheese
  • Lasagna noodles (regular or no-boil)
  • For the White Sauce (Béchamel):
  • Butter
  • All-purpose flour
  • Milk (whole milk preferred)
  • Nutmeg (optional)
  • Salt and pepper

Instructions

  1. Preheat oven to 375°F (190°C).
  2. Sauté mushrooms in olive oil or butter until browned. Add garlic and spinach; cook until wilted. Season and set aside.
  3. Make béchamel: Melt butter, whisk in flour, cook for 1–2 mins. Slowly add milk, cook until thick. Season with salt, pepper, and nutmeg.
  4. Mix ricotta with egg and Parmesan.
  5. In a baking dish, layer béchamel, noodles, ricotta mixture, mushroom-spinach filling, mozzarella, and more béchamel. Repeat layers and finish with sauce and cheese on top.
  6. Cover with foil, bake for 30 mins. Uncover and bake 10–15 mins until golden and bubbly.
  7. Rest for 10–15 mins before serving.

Notes

  • Use cremini, baby bella, shiitake, or portobello mushrooms for different flavor profiles.
  • Frozen spinach works well—just drain it thoroughly.
  • Can be made vegan with dairy-free cheese, milk, and butter.
  • Lasagna freezes and reheats beautifully—perfect for make-ahead meals.
  • Prevent watery lasagna by cooking down spinach and mushrooms and thickening béchamel.
