One-Step Wrap & Reheat Try this method for storing and reheating all your leftovers in the same wrap. Spoon individual meal portions on a sheet of Reynolds Wrap® Heavy Strength Aluminum Foil. Wrap up the top and ends with double folds to make a packet and refrigerate. Heat up the packet on a cookie sheet in a preheated 450°F oven for about 20 to 25 minutes until food is hot. Eat a great meal with no mess or clean up.
Reheated Leftovers Temperatures of reheated leftovers should reach 165°F, and if reheating gravy alone, it should come to a rolling boil.
