  • 3 cloves garlic minced
  • 2 tbsp olive oil for sautéing

Béchamel Sauce

  • 4 tbsp unsalted butter for the sauce base
  • 4 tbsp all-purpose flour to thicken the sauce
  • 4 cups whole milk providing richness
  • 1/4 tsp ground nutmeg for flavor

Lasagna Layers

  • 12 pieces lasagna noodles cooked al dente
  • 2 cups shredded mozzarella cheese for a melty finish
  • 1/2 cup grated Parmesan cheese for a golden crust

Instructions

Preparation

  • Preheat your oven to 375°F (190°C). Prepare your ingredients.
  • In a large skillet, heat olive oil over medium heat and add sliced mushrooms. Cook until golden brown, about 5-7 minutes.
  • Add minced garlic to the skillet and sauté for another minute until fragrant. Then add the chopped spinach and cook until wilted. Season with salt and pepper.
  • In another saucepan, melt butter over medium heat. Stir in flour to form a roux and cook for 1-2 minutes.
  • Gradually whisk in milk and cook until thickened. Season with nutmeg, salt, and pepper.
  • Cook lasagna noodles according to package instructions, drain and set aside.

Assembly and Baking

  • Spread a thin layer of béchamel sauce on the bottom of a baking dish.
  • Layer with lasagna noodles, followed by spinach and mushroom mixture, more béchamel, and mozzarella.
  • Repeat layers and top with a generous layer of Parmesan.
  • Cover with foil and bake for 25 minutes, then remove foil and bake for an additional 15 minutes.
  • Let the lasagna rest for 10 minutes before slicing. Garnish with fresh parsley.

Notes

To prevent sogginess, drain spinach well. You can customize by adding other veggies or proteins.
