Directions

Assemble lasagne: Preheat oven to 425°F.

Toss cheeses together. Spread 1/2 cup sauce in a buttered 13- by 9- by 2-inch glass baking dish (or other shallow 3 quart baking dish) and cover with 3 pasta sheets, leaving spaces between sheets. Spread with 2/3 cup sauce and one third of filling, then sprinkle with a heaping 1/2 cup cheese. Repeat layering 2 more times, beginning with pasta sheets and ending with cheese. Top with remaining 3 pasta sheets, remaining sauce, and remaining cheese.

Tightly cover baking dish with buttered foil and bake
lasagne in middle of oven 30 minutes. Remove foil and bake until golden and bubbling, 10 to 15 minutes more. Let lasagne stand 15 to 20 minutes before serving.

Cooks’ note: Filling and sauce can be made 1 day ahead and kept separately, covered and chilled. Bring to room temperature before assembling.
