Defrost Turkey

Be sure your 25-pound turkey is defrosted by the morning of the day you want to cook it. For instance, if you want to roast it on Thanksgiving, I suggest getting it into the refrigerator the Friday before. This is because I love to start the salt dry brine on Sunday and the turkey should not be solid frozen.

When thawing in a refrigerator, it takes 4-5 days to have a fully defrosted turkey that weighs 25 pounds. If you want to brine it, add a few more days to your calendar. This will help you have a turkey that is ready.

Salt Brine a Turkey

I always suggest you start defrosting early so you can brine your holiday bird. Brining the turkey will help keep it moist, juicy, & succulent. For a turkey everyone will be wanting seconds of, make sure you try my easy process for the best dry brine recipe. 

If you are making your turkey for Thanksgiving day, which in America falls on a Thursday every year, you will need to start the dry brine on Sunday. Make sure your turkey has already started to defrost. It does not need to be completely defrosted but around ½-way through is fine.

How to Prep a Turkey before Cooking

Once your turkey is defrosted, next up you want to prep it for the oven. Get out your large roasting pan and rack. If you are wondering how big a roasting pan you need for a turkey that is 25 pounds or larger, it is a pretty big one. Ideally use an 18-inch pan and a rack that fits in it.

The last step before roasting a turkey is to season it. Use whatever recipe you like, but below I have outlined how I dress mine up. Remove the parts in the cavity of the bird and aromatics like citrus, garlic, & herbs. Then rub on softened butter and some seasonings.

Time & Temperature for 25-Pound Turkey

You can cook a turkey at either 325° or 350° in the oven. Below is the information on how long to cook a turkey depending on the temperature and timing you want to use. Whether your turkey is unstuffed or full of stuffing, here are how many hours it will take to roast in the oven so it is ready on time for your Thanksgiving, Christmas, Easter, or other holiday meal.

I recommend cooking your turkey both covered and uncovered. I like to loosely tent foil over the turkey for the first half of the cooking process. Once it is halfway done, I remove the foil and let the skin begin browning so it is crispy and amazing.

Best Instant-Read Thermometer

Always use a meat thermometer to check internal temperatures when cooking a turkey. I like to use an instant-read thermometer. I prefer this over leaving one in the turkey the entire time it cooks.

An instant-read thermometer is the best way to check that your turkey is ready. With an instant-read thermometer, you can check several places on your turkey in a few seconds. It's best to check the breast, thigh, & stuffing if your bird is stuffed. These recommendations for checking doneness are even shared by Butterball.

ALL TIMES SHARED HERE ARE ESTIMATES - EVERY TURKEY, OVEN TEMPERATURE, ROASTING PAN, ELEVATION, AND MORE CAN ALTER THE COOKING TIMES.

25-Pound Unstuffed Turkey

Once your 25-pound turkey is in the pan and ready to go into the oven, make sure you set a timer to be sure you check it on time. If you are cooking the turkey at 325°, it will take 5 ½ - 6 hours to cook. At 350°, it will take 5-5 ½ hours. Place your turkey covered in foil in the oven and set a timer for 2 ½ hours.

Once the halfway point is done, remove the foil so the turkey can cook uncovered for the final cooking time. I suggest using an instant-read thermometer and starting checking the thickest part of the thigh after another 2 ½ hours. You want the turkey to reach an internal temperature of 175° at the thigh.

Remember that at 325° it will take 30-60 minutes longer for the turkey to cook than if you cooked it at 350°. This is for a turkey without stuffing.

• 350° a 25-lb turkey takes 5-5 ½ hours to cook in the oven
• 325° a 25-lb turkey takes 5 ½ - 6 hours to cook in the oven

25-Pound Turkey with Stuffing

If your 25-pound turkey is stuffed, in the pan, and ready for the preheated oven, time to set your timer. A stuffed turkey takes longer to cook than one that is unstuffed. If you are cooking the turkey at 325°, it will take 7 ½ - 8 hours to cook. At 350°, it will take 6 ½ - 7 hours.

Place the stuffed turkey covered in foil in the oven and set a timer for 2 hours. Remove the foil and reset the timer for 1 hour. Use an instant-read thermometer and start checking the thickest part of the thigh around the 3-hour mark. You want the turkey to reach an internal temperature of 175°.

Remember that at 325° it will take roughly an hour longer for the turkey to cook than if you cooked it at 350°. This is for a turkey with stuffing.

• 350° a 25-lb stuffed turkey takes 6 ½ - 7 hours to cook in an oven
• 325° a 25-lb stuffed turkey takes 7 ½ - 8 hours to cook in an oven

25-Pound Turkey in a Roasting Bag

If you like to cook your turkey in a bag, such as Reynold's bag, here is how long it will take for a 25-lb turkey. Cooking a turkey in an oven bag does speed up the cooking time. Since a turkey cooked in one of them cooks faster, I do not recommend stuffing a turkey when you cook in a bag.

Wondering how to cook a large turkey faster. A roasting bag is a way to go. When cooking a 25-pound unstuffed turkey in an oven bag at 350°, it takes 4 - 4 ½ hours. I suggest starting to check the internal temperature of the turkey at the 3 ½ -hour mark. If the thickest part of the thigh is 175°, it is done.

Resting Time

Any sized turkey, chicken, roast, steak, etc will stay juicier if you let it rest before slicing into it. What that means for a 25-pound turkey is that make sure you add some resting time to your overall prep and cooking calculations.

The recipe card below adds an hour for resting time. Once the turkey comes out of the oven, let it rest on the counter loosely covered with foil. This final hour is a great time to prep and cook other dishes in your oven that is now empty and already preheated - perfect!

Other Sizes

If you have decided that next time you need a smaller turkey and wondering if it will save time, here are some great guides. For turkeys that weigh less than 25 pounds, these cooking times by temperature will help for your next holiday meal.

25-Pound Turkey Feeds How Many People?

When estimating how many pounds of turkey per person, it is best to take into account those you are inviting. A combination of children, teens, and adults will feed more than a party with all adults that are big eaters.

On average, it is best to estimate 1 - 1 ½ pounds per person. For a family of adults and children that are average eaters, a 25-pound turkey will feed 20 people. If it is all adults or big eaters, estimate it to feed 16 people.

With another protein and many hearty sides and part of a large Thanksgiving meal, a 25-pound turkey will feed roughly 17-23. After all, everyone wants to save room for dessert, right!?!

Refrigerating & Freezing Leftovers

Leftover turkey stores well in the refrigerator. Place slices and turkey pieces in an air-tight container. Store in the refrigerator for up to 5 days. No need to remove the bones before storing but you can if you wish. Save those bones to make bone broth using poultry bones in a pressure cooker!

Turkey also freezes well and easily. Place the leftover Thanksgiving turkey in an air-tight container. Store it with or without the bones. I prefer removing the meat from the bones before freezing. It saves freezer space but it also helps it defrost faster and more evenly later.

To defrost the leftover frozen turkey, place your container in the refrigerator. Let it thaw for 1-3 days, depending on the amount. Enjoy cold in a sandwich or salad. I love it in a bowl of comforting Pot Pie Soup.

Or reheat leftover turkey in a toaster oven or oven at 350° for 5-20 minutes depending on how much you are warming up (and if it thin slices or the whole turkey leg - haha!)

Recipes for Turkey Leftovers

When you make a 15-pound Thanksgiving turkey you will probably have leftovers (unless you are feeding a small army!) Besides yummy sandwiches, here are some great recipes and ideas for using up leftover turkey slices & other pieces.

Trade out the protein or add the turkey to the existing recipes below and continue getting your turkey fix for days after Thanksgiving or Christmas. (The kale salad or the curry are my favorite ways to use up the turkey!)

• Pot Pie Soup
• Butternut Squash, Apple, and Kale Salad with Honey Dijon Vinaigrette
• Zucchini, Chickpea, and Potato Curry
• Toaster Oven Grilled Cheese Sandwich

TURKEY FAQS

Is it better to cook a turkey at 325° or 350°?

You can cook a turkey at either temperature, 325° or 350°. I personally cook at 325° for a low and slow oven-roasted turkey that is juicy every year.

I do not recommend cooking it at a higher temperature to speed things up. It simply dries out the skin and outer meat too fast while the internal meat like the thigh could still be unsafe & undercooked.

How do I keep my turkey moist?

Here are my top tips for helping keep your turkey moist and juicy. Begin with a dry brine for several days before cooking. Before cooking the turkey, coat the skin with softened butter. Also, cover the turkey in foil for the first ½ of cooking to keep the moisture from escaping.

Finally, make sure you let the turkey rest for at least a half hour before carving it. Even the breast will be moist after oven cooking. All of these ideas are the best way to keep a turkey from drying out.

Can you add water to the bottom of a turkey roasting pan?

If you follow my recipe and brine it, your turkey will be moist. Adding water to the pan when cooking, is not one of those things. You do not want to "steam" your bird, you want to roast it slowly and evenly. The water at the bottom will add steam to the oven plus it will be like a hot bath that the turkey is sitting in.

Even if just a few inches, that lower part of the bird will almost boil and cook faster than the rest of the turkey. Also, as the turkey juices and melted butter collect at the bottom of the pan, why would you want them watered down? They taste so much better when concentrated with full flavor.

What temperature should the breast of a turkey be when done?

There are 3 places you may check your turkey for doneness and each has a different reading. Using an instant-read thermometer, you want the turkey breast to read 165° and the thickest part of a thigh to read 175°. If you have stuffing, check that as well for a temperature of 165° also.

IMPORTANT - the turkey will continue to "cook" as it rests. It will likely go up another 5° during that time and that IS OK! It is best to let the turkey rest for about 30 minutes before cutting into it & it will be perfectly moist and done. Tent it with foil and wait until later before you start carving it. If you carve it too soon, the juices will run out and dry out the meat.

If your bird has stuffing, the stuffing needs to be safe to eat as well. You do not want undercooked stuffing that may be harmful to consume. Make sure the stuffing is 165° so that any turkey juices that have dripped into it are also safe.
