Instructions
Prepare the Spinach Ricotta:
Heat olive oil in a large skillet over medium-high heat. Add the onion, 1/2 teaspoon of salt, and 1/4 teaspoon of pepper. Cook, stirring occasionally, until the onion is translucent (about 4 minutes). Add the spinach in batches, stirring until all the spinach wilts (about 5 minutes). Transfer the spinach to a mesh strainer and press to remove excess liquid. Set aside 1 1/2 cups of the spinach mixture for layering later. Place the remaining spinach in a food processor and pulse until finely chopped. Transfer to a large bowl and mix with ricotta, Parmesan, egg, and the remaining salt and pepper. Set aside.
Make the Mornay Sauce:
In a cleaned skillet, melt butter over medium heat. Add garlic and cook until fragrant, about 1 minute. Stir in the flour to make a roux, cooking for about 1 minute until light golden. Gradually whisk in milk, bringing the mixture to a simmer. Cook, stirring, until the sauce thickens (about 3 minutes). Whisk in the Gruyère cheese until melted and smooth. Remove from heat and stir in salt and nutmeg.
Cook the Noodles:
Cook lasagna noodles according to the package instructions until al dente. Drain and rinse with cold water. Pat dry between paper towels.
Assemble the Lasagna:
Preheat the oven to 350°F. Spread 3/4 cup of the Mornay sauce on the bottom of a 13x9-inch baking dish. Add 3 lasagna noodles in an even layer. Spread 1 cup of the spinach ricotta mixture over the noodles, then top with 1/2 cup of the reserved spinach mixture, 1 cup of mozzarella, and 3/4 cup of Mornay sauce. Repeat this layering process two more times. Finish with the last 3 noodles, the remaining Mornay sauce, and 1 cup of mozzarella.
Bake the Lasagna:
Cover the lasagna with aluminum foil sprayed with cooking spray to prevent the cheese from sticking. Bake for 30 minutes, then remove the foil and bake for another 15 minutes until bubbly. Increase the oven temperature to broil and broil the lasagna until the cheese is browned and bubbly, about 3-5 minutes. Remove from the oven and let it stand for 30 minutes before serving.
