How to Make It

Follow these simple steps to create your delicious lasagna.

Prepare the White Sauce

Melt the butter in a saucepan over medium heat. Whisk in the flour and cook for 1-2 minutes until smooth. Gradually whisk in the milk until smooth. Bring to a simmer, stirring constantly. Reduce heat and simmer for 5-7 minutes, or until thickened. Stir in the nutmeg, salt, and pepper. Remove from heat and set aside.

Prepare the Vegetable Filling

Heat the olive oil in a large skillet over medium heat. Add the onion and cook until softened, about 5 minutes. Add the garlic and cook for 1 minute more. Add the bell peppers and zucchini and cook until tender-crisp, about 5-7 minutes. Stir in the spinach, salt, and pepper. Remove from heat and let cool slightly.

Combine Cheese Mixture

In a large bowl, combine the ricotta cheese, Parmesan cheese, and egg. Stir in the cooled vegetable mixture.

Cook the Lasagna Noodles

Cook the lasagna noodles according to package directions. Drain and rinse with cold water.

Assemble the Lasagna

Preheat oven to 375°F (190°C). Spread a thin layer of white sauce in the bottom of a 9×13 inch baking dish. Layer 3 lasagna noodles over the sauce. Spread half of the vegetable filling over the noodles. Sprinkle with 1 cup (112g) of mozzarella cheese. Repeat layers: white sauce, noodles, vegetable filling, and 1 cup (112g) mozzarella cheese. Top with the remaining noodles and white sauce. Sprinkle with the remaining 1 cup (112g) of mozzarella cheese.

Bake

Cover the baking dish with foil and bake for 25 minutes. Remove the foil and bake for an additional 20-25 minutes, or until the cheese is melted and bubbly and the lasagna is heated through.
