This recipe makes one large lasagna, but you can easily make two smaller versions in eight-inch baking dishes. Enjoy one for dinner tonight, and freeze the other for later. Or add sausage to one (see variation below) and keep the other meat-free.

Ingredients
Preparation
Step 1
Preheat oven to 400°F. Whisk together ricotta, eggs, 1/2 teaspoon salt, and 1/4 teaspoon pepper. Squeeze spinach to remove as much liquid as possible, and add to ricotta mixture; stir well to combine.
Step 2
Spread a thin layer of tomato sauce in the bottom of a 9-by-13-inch glass baking dish. Arrange 4 noodles on top. Spread one-third of the ricotta mixture over noodles, followed by one-third of the remaining tomato sauce; sprinkle with one-third of the fontina cheese. Repeat to make two more layers, ending with fontina. (At this point, the lasagna can be tightly wrapped in plastic and frozen up to 2 months. Thaw overnight in the refrigerator before proceeding.)
Step 3
Cover with aluminum foil; bake 30 minutes (40 minutes if previously frozen). Remove foil; continue baking until golden brown on top and sauce is bubbling, about 15 minutes more. Let cool slightly before cutting into squares and serving.
Sausage Variation
Step 4
Remove casings from hot or sweet Italian sausage (you will need about 1 pound for a large lasagna and 8 ounces for a small one). Cook in a medium skillet over medium heat, breaking up meat with a spoon, until no longer pink, about 10 minutes. Let cool. Follow recipe above, layering sausage in thirds after the tomato sauce.
