Ingredients

White Sauce

2 tablespoons unsalted butter ($0.22)
2 tablespoons all-purpose flour ($0.03)
2 cups milk ($0.38)
½ teaspoon Italian seasoning ($0.04)
½ teaspoon garlic powder ($0.04)
½ teaspoon onion powder ($0.04)
½ teaspoon salt ($0.01)
¼ teaspoon ground black pepper ($0.02)
1 pinch ground nutmeg, optional ($0.01)
¼ cup Parmesan cheese, shredded ($0.50)

Lasagna Filling

Lasagna noodles, oven-ready or cooked ($1.20)
1 tablespoon olive oil or butter ($0.05)
1 medium onion, chopped ($0.48)
2 cups cooked turkey, shredded ($0.00)
1 cup frozen spinach, thawed and squeezed dry ($0.30)
1 ½ cups mozzarella cheese, shredded ($1.44)
¼-½ cup Parmesan cheese, shredded ($0.75)

Instructions

Prepare the noodles. Cook lasagna noodles according to package directions if not using oven-ready noodles. Drain and set aside.
Cook the filling. Heat oil or butter in a skillet over medium heat. Cook the onion until soft. Stir in the turkey and spinach and warm through. Set aside.
Make the white sauce. Melt the butter in a saucepan over medium heat. Whisk in the flour until smooth. Slowly whisk in the milk and simmer until thickened. Stir in Italian seasoning, garlic powder, onion powder, salt, black pepper, and nutmeg. Remove from heat and stir in the Parmesan.
Assemble. Spread a thin layer of sauce in the bottom of a baking dish. Layer noodles, turkey filling, sauce, and cheeses. Repeat layers, finishing with noodles and sauce.
Bake. Cover with foil and bake at 350°F for 40 to 45 minutes. Uncover, sprinkle with remaining cheese, and bake or broil until bubbly and lightly golden.
Rest and serve. Let the lasagna rest for 10 minutes before slicing.

Notes

Turkey. Light meat, dark meat, or a mix all work. Shred finely for even layers.
Spinach. Thaw completely and squeeze dry to prevent excess moisture.
Make ahead. Assemble up to 24 hours in advance and refrigerate. Add 10 to 15 minutes to bake time if cold.
Freezing. Freeze before or after baking. Thaw overnight and reheat at 350°F until warmed through.
Add-ins. Mushrooms, roasted vegetables, or extra spinach can be added to bulk it up.
