Remembering you have leftover chicken, pizza or turkey in the fridge can feel like a siren call to happiness. But depending on the type of food you’re dealing with, figuring out whether or not Wednesday’s dinner can safely be eaten as Friday’s lunch can feel like a guessing game. If you too are Googling “how long do leftovers stay good” and asking everyone you know the same question, here’s the complete run-down.

Leftover Chicken

Storage conditions will cause the shelf life of cooked chicken to vary from kitchen to kitchen. If your fridge is exceptionally cold and the chicken is sealed properly, it can last for more than four days. However, a good rule of thumb for the average fridge is to toss cooked chicken after four days, which is when bacteria usually begins to grow. If you’re unsure whether or not the chicken is safe to eat, look for any signs of a sour smell or slightly slimy texture. If you find any of these traits, discard the chicken without tasting it first.

Leftover Stuffing and Gravy

While some might argue that half the fun of popular holiday dinners is the leftovers, both stuffing and gravy have a surprisingly short shelf life. Stuffing — which is often soaked through with meat drippings — shouldn’t be consumed after a maximum of two days in the fridge. The same two-day rule should be applied to the gravy, which should always be brought to a rolling boil to properly kill bacteria before serving again. The good news is that freezing excess stuffing and gravy will extend the shelf life for up to four months.

Leftover Pizza

Any food with meat and cheese that’s left unrefrigerated for more than two hours can cause foodborne illness. This includes the half-eaten pizza box you left out just in case “someone” wanted another slice. Place your pizza in the fridge within two hours of preparation and it will last for up to four days, three days being the recommended shelf life of the average slice. After that, bacteria can begin to grow and lead to food poisoning.

Leftover Lasagna

Cooked lasagna keeps in the refrigerator for up to five days if stored in a tightly sealed container to keep out excess moisture and other contaminants. The best way to determine whether or not lasagna has turned is to look for dried-out noodles or a sour smell emanating from the tomato sauce and cheese.

Leftover Pad Thai and Takeout Noodles

Pad Thai and other popular takeout noodle dishes will generally last up to three days in the refrigerator. Due to heavy sauces that can contribute to a soggy texture, these dishes can sometimes taste bad before they actually go bad. To be safe, always reheat noodles with meat and animal products to a temperature of 165°F or higher in order to kill any outstanding bacteria before eating.

Leftover Beef 

Are you reaching for last week’s beef tenderloin leftovers or prime rib leftovers, but not sure if it’s still good to eat? If properly stored, the general rule of thumb for cooked beef is three to four days in the fridge or up to six months in the freezer. If it is giving off a bad smell or it looks slimy or sticky, it’s definitely time to toss that goodbye.
