Baked in the oven with a lively beef filling, this casual “soft taco” dinner is just as comforting as the traditional Italian manicotti, but with a little more flair–and heat. This dish is a great make-ahead for a fiesta party.
Instead of baking, place foil-covered dish in the refrigerator for up to 1 day or tightly wrap and freeze. To bake, defrost casserole. Then, cover and bake for 1-1/4 hours. Remove foil, sprinkle with cheese and continue baking until cheese is melted and manicotti is hot.
