Ingredients

1/3 cup butter, cubed
1 medium onion, chopped
1 garlic clove, minced
1/2 cup all-purpose flour
1 teaspoon salt
3-1/2 cups 2% milk
4 cups shredded part-skim mozzarella cheese, divided
1 cup grated Parmesan cheese, divided
1 teaspoon dried basil
1 teaspoon dried oregano
1/2 teaspoon white pepper
1 carton (15 ounces) whole-milk ricotta cheese
1 tablespoon minced fresh parsley
9 lasagna noodles, cooked and drained
2 packages (10 ounces each) frozen chopped spinach, thawed and squeezed dry
1 jar (8.1 ounces) prepared pesto

Directions

Preheat oven to 350°. In a large saucepan melt butter over medium heat; add onion. Cook and stir until tender, 4-6 minutes. Add garlic; cook 1 minute longer. Stir in flour and salt until blended. Gradually whisk in milk. Bring to a boil; cook and stir until thickened, about 1 minute. Stir in 2 cups mozzarella cheese, 1/2 cup Parmesan cheese, basil, oregano and pepper; set aside.
In a large bowl, combine ricotta cheese, parsley and remaining 2 cups mozzarella; set aside. Spread about 1-1/2 cup cheese sauce into a greased 13x9-in. baking dish; top with 3 noodles and half of each of the following: ricotta mixture, pesto and spinach. Repeat layers. Top with remaining noodles and cheese sauce. Sprinkle with remaining 1/2 cup Parmesan.
Bake, uncovered, until heated through and cheese is melted and sauce is bubbly, 35-40 minutes. Let stand 15 minutes before serving.
