How to Reheat a Casserole in the Oven

One of the defining characteristics of casseroles, regardless of the type, is creaminess or juiciness. You will want to maintain this during reheating to fully enjoy this dish. Often these recipes actually taste better the day after, because the ingredients have fused together so well. Here’s my step-by-step method for reheating your casserole and reveling in that day-after blend of flavors. Plan on reheating for approximately 20 minutes time.

  • Step 1: If your casserole has been refrigerated, remove it and set it aside for at least 20 minutes until it reaches room temperature.
  • Step 2: Preheat your oven to 350° F.
  • Step 3: Place your leftovers of the casserole in a baking dish. If you have one large portion, cut it into smaller pieces to help the inside of the casserole to heat more quickly and evenly.
  • Step 4: Cover the dish or pan with casserole leftovers. If the pan doesn’t have its own cover, you can cover it with aluminum foil. This is really important and the key to success, because it will preserve the natural juices and help to avoid burning the edges of your leftover casserole.
  • Step 5: Bake for approximately 20 minutes. If you only have a few pieces, or if they are small or thin, shorten the reheating time to roughly 15 minutes.

Once your casserole has been reheated, allow it to sit for about 2 minutes before serving.

Reheating Fried Chicken in an Oven

Leftover fried chicken? It was so good yesterday, that you just want another bite of that crispy, juicy meat today. And since you want it crispy and juicy, you don’t want to eat it cold. Your conventional oven can come to the rescue so that your fried chicken leftovers will taste as if they came directly from a deep fryer after only 20 minutes in your conventional oven.

  • Step 1: Preheat your oven to 400° F.
  • Step 2: Remove your chicken from the refrigerator and let it sit at room temperature for approximately 15 minutes.
  • Step 3: While you are waiting, fit a rack onto a baking sheet.
  • Step 4: Position your chicken pieces on the rack allowing space. The space under and between the pieces will permit the air to circulate better. (If you don’t have a rack, try lining your baking sheet with foil.)
  • Step 5: Position the tray with the chicken directly in the center of your oven and cook it for 15 to 20 minutes. The correct amount of time will depend on the cut of the chicken pieces, size, and thickness. To avoid having your chicken dry out, keep an eye on it, checking thighs and legs after 10 minutes and chicken breasts after 15 minutes.
  • Step 6: Once sufficiently crispy for your taste, remove and enjoy.
