Experts and BHG readers answer.
Can lasagna be made ahead?
You can assemble lasagna, but do not bake. Cover and refrigerate up to 24 hours or freeze up to 1 month. (If frozen, thaw in the refrigerator before baking-this may take 1 to 2 days.) Bake, covered, in a 375°F oven for 40 minutes. Uncover and bake for 20 to 25 minutes more or until heated through. Let stand 15 minutes before serving.
