Whether you have purchased a pre-cooked bird from the grocery store or you are staring at a massive pile of Thanksgiving leftovers, knowing how to warm up pre cooked turkey is a culinary skill that can save your dinner. The primary challenge with reheating turkey is the meat’s tendency to dry out. Because turkey is lean, especially the breast meat, it can quickly turn from succulent to sawdust if you aren’t careful with your methods.
This guide will walk you through the science of reheating, the best equipment to use, and step-by-step instructions to ensure your turkey tastes just as good—if not better—than the day it was first roasted.
Why Reheating Turkey is a Delicate Science
The reason turkey often becomes tough during reheating is due to protein denaturation. When heat is applied for a second time, the muscle fibers contract further, squeezing out any remaining moisture. To combat this, you must focus on two things: moisture replacement and gentle heat.
If you are working with a whole pre-cooked turkey that was frozen, the first step is always a proper thaw. Never attempt to reheat a fully frozen whole turkey, as the outside will reach dangerous temperatures while the inside remains an icy block. Always thaw in the refrigerator for 24 hours for every 4 to 5 pounds of meat.
Preparation: The Secret is in the Liquid
Before you even turn on the oven, you need to prepare your “moisture shield.” Reheating turkey without adding liquid is a recipe for disappointment. The best liquids to use include:
- Turkey or chicken broth
- Giblet gravy
- Melted butter with a splash of white wine
- Water (as a last resort, though it adds no flavor)
By creating a humid environment, you allow the steam to penetrate the meat, keeping the proteins supple.
The Best Method: Low and Slow in the Oven
The oven is the most reliable method for warming up a whole or sliced pre-cooked turkey. It provides consistent, surrounding heat that mimics the original cooking process.
Step-By-Step Oven Instructions
First, preheat your oven to 325°F. While a higher temperature might seem faster, it will likely sear the exterior before the core is warm.
If you are reheating a whole turkey, place it in a large roasting pan. Pour at least two cups of broth into the bottom of the pan. Smear the skin with butter or oil to help it crisp up slightly, though it will never be quite as crunchy as a fresh bird. Cover the entire pan tightly with aluminum foil. This is crucial; if steam can escape, the turkey will dry out.
For sliced turkey, lay the pieces in a baking dish in a single layer if possible. Drizzle a generous amount of broth or gravy over the slices. Cover the dish tightly with foil.
Timing and Temperature
The goal is to reach an internal temperature of 165°F. This is the USDA recommended temperature for food safety when reheating poultry.
Use a meat thermometer to check the thickest part of the thigh or the center of the breast slices. For a whole turkey, expect this to take about 10 to 12 minutes per pound. For slices, it usually takes 20 to 30 minutes total.
Using a Slow Cooker for Sliced Turkey
If you have a lot of side dishes occupying the oven, a slow cooker is a fantastic alternative for warming up pre-cooked turkey slices. This method is particularly good for keeping meat moist for a long period, such as during a buffet-style party.
Place your turkey slices or shredded meat into the slow cooker. Add enough broth or gravy to cover the bottom of the insert by about an inch. Set the slow cooker to the “Low” setting. Do not use “High,” as this can boil the meat and make it stringy.
Depending on the amount of meat, it will take about 1 to 2 hours to reach 165°F. Once it reaches that temperature, you can switch the setting to “Warm” to keep it ready for serving.
Reheating in the Microwave: The Quick Method
The microwave is the fastest way to warm up pre-cooked turkey, but it is also the easiest way to ruin it. Use this only for individual portions and follow these steps to maintain quality:
- Place the turkey slices on a microwave-safe plate.
- Add a tablespoon of broth or water over the meat.
- Cover the plate with a damp paper towel or a microwave-safe lid.
- Use the “Power Level 5” or 50 percent power setting. Using full power will cause the water molecules to vibrate too fast, toughening the meat.
- Heat in 1-minute intervals, rotating the meat halfway through, until it is steaming.
Utilizing the Sous Vide for Professional Results
If you own a sous vide immersion circulator, you have the ultimate tool for reheating turkey. This method is impossible to overcook because the water bath remains at a constant temperature.
Seal your turkey (slices or pieces) in a vacuum bag with a pat of butter or a little broth. Set your sous vide to 150°F or 160°F. Since the turkey is already cooked, you are just bringing it up to temperature. Submerge the bag for about 45 to 60 minutes. The result is meat that is exactly as moist as when it was first bagged.
Calculating Reheat Times for Large Quantities
When planning a large dinner, you may need to estimate how much time the oven will be occupied. While variables like oven calibration and pan material matter, you can use a basic calculation for a whole turkey.
The formula for estimated reheat time is: Total Minutes = Weight in pounds x 12
For example, if you have a 12 pound turkey: 12 x 12 = 144 minutes (approximately 2 hours and 24 minutes).
Always start checking the temperature with a probe thermometer about 30 minutes before the calculated time ends to avoid overcooking.
Tips for Crispy Skin
The one downside to the “moisture and foil” method is that it leaves the turkey skin soft and soggy. If you want to crisp it up, remove the foil during the last 15 minutes of the reheating process. Turn the oven up to 400°F or turn on the broiler. Brush the skin with a bit of melted butter and watch it closely to ensure it doesn’t burn.
Food Safety and Storage
Once you have reheated the turkey, it should be consumed immediately. You should not reheat the same piece of turkey more than once. Every time the meat is cooled and reheated, it enters the “danger zone” (between 40°F and 140°F) where bacteria can grow rapidly.
If you have a whole pre-cooked turkey, only reheat the portion you plan to eat that day. Keep the rest in the refrigerator until needed. Reheated turkey should stay fresh in the fridge for 3 to 4 days after the initial cooking or after opening a vacuum-sealed store-bought package.
FAQs
How do I stop my turkey from drying out when reheating?
The best way to prevent dryness is to add a liquid like chicken or turkey broth to the pan and cover the meat tightly with aluminum foil. This creates a steam-filled environment that hydrates the muscle fibers. Additionally, reheating at a lower temperature, such as 325°F, ensures the meat warms through without the outer layers becoming overcooked.
Can I reheat a pre-cooked turkey from frozen?
It is highly recommended to thaw the turkey completely in the refrigerator before reheating. Reheating from frozen results in uneven cooking, where the outside may become dry and overcooked while the inside remains cold or frozen. If you must reheat from frozen, it will take significantly longer, and you must use a very low temperature and plenty of liquid to prevent the exterior from burning.
What temperature should the turkey reach?
For safety reasons, the USDA recommends that all reheated poultry reach an internal temperature of at least 165°F. Use a digital meat thermometer to check the thickest part of the meat, making sure the probe does not touch the bone, as bones conduct heat differently and can give an inaccurate reading.
Is it better to reheat turkey whole or sliced?
Slicing the turkey before reheating is generally better for moisture retention and even heating. Slices have more surface area to absorb broth or gravy, and they reach the safe temperature of 165°F much faster than a whole bird. However, if you want the visual appeal of a whole bird for a dinner party, reheating it whole in a roasting pan with broth and foil is the way to go.
How long can pre-cooked turkey stay in the fridge?
A pre-cooked turkey, whether store-bought or leftovers from a home-cooked meal, should be consumed within 3 to 4 days if kept in a refrigerator set at 40°F or below. If you cannot finish the turkey within that timeframe, it is best to freeze the meat in airtight containers or freezer bags, where it will remain safe for several months.
