Lasagna Primavera

This is such a great recipe- I want to start making it often so I can master it- and be able to prepare it in my sleep. It has a white sauce, not tomato. It is so jam-packed with vegetables, I love serving it to my family who would otherwise turn their noses up at all the carrots, spinach and peas. Perfect springtime dinner. When I make this again, I will prep the veggies in the morning to save time during assembly, and I will divide the recipe in 1/2, baking one half for dinner that night and freezing the other half.

Lasagna Primavera

Serves 8

1/4 cup olive oil, plus more for foil
1/2 cup all-purpose flour
3 garlic cloves, minced
6 cups whole milk
2 packages (10 ounces each) frozen chopped spinach, thawed and squeezed dry
1 package (10 ounces) frozen peas
1/2 pound carrots (4 to 5), halved lengthwise and thinly sliced
Coarse salt and ground pepper
1 container (15 ounces) part-skim ricotta (about 2 cups)
1 large egg
1 package (9 ounces) no-boil lasagna noodles (12 to 16 noodles)
1 pound part-skim mozzarella, shredded
1 cup grated Parmesan

1. Preheat oven to 400 degrees. In a large saucepan, heat oil over medium; add flour and garlic. Cook, stirring constantly, 2 to 3 minutes (do not let flour mixture darken); whisk in milk. Bring to a boil; reduce to a simmer, and cook, whisking occasionally, until thickened, 3 to 5 minutes. Add spinach, peas, and carrots; season with salt and pepper. Set sauce aside.
2. In a medium bowl, combine ricotta, egg, 1/2 teaspoon salt, and teaspoon pepper.
In the bottom of a 9-by-13-inch baking dish, spread a thin layer of vegetable sauce. Layer noodles, half the remaining vegetable sauce, another noodles, half the ricotta mixture, half the mozzarella, and half the Parmesan; repeat.
3. Cover dish with lightly oiled aluminum foil, and place on a large rimmed baking sheet. Bake 45 minutes, uncover, and bake until bubbling and browned, about 20 minutes more. Let cool 10 to 15 minutes before serving.

To Freeze: Assemble lasagna but do not bake. Cover lasagna tightly with plastic wrap, then aluminum foil; freeze up to 3 months. To Bake From Frozen: Remove plastic wrap; cover baking dish with lightly oiled aluminum foil, and place on a large rimmed baking sheet. Bake at 400 degrees for 1 1/2 hours. Remove foil, and bake until bubbling and browned, about 30 minutes more. Let cool 10 to 15 minutes before serving.
