You're staring at the bird. It’s 13 pounds of poultry sitting in your sink or on your counter, and the pressure is starting to mount because people are coming over and they expect a dinner that isn't either raw at the bone or dry as a desert. Honestly, the biggest mistake people make is looking at a generic chart on the back of a frozen bag and thinking that’s the law. It isn't.
If you want to know how long to cook 13 lb turkey in oven, you have to account for more than just the weight. We’re talking oven calibration, whether you stuffed the thing, and how often you’re opening that oven door to peek. Every time you open the door, you lose about 25 degrees of heat. Stop doing that.
Generally speaking, a 13-pound turkey is going to take you between 3 and 4 hours. But let's get into the weeds of why that range is so wide and how you can actually hit the sweet spot without ruining your afternoon.
The 13-Pound Sweet Spot: Temperature vs. Time
Most experts, including the folks over at Butterball and the USDA, suggest a standard oven temperature of 325°F (165°C). At this temperature, an unstuffed 13-pound turkey usually needs about 15 minutes per pound. Math says that’s 3 hours and 15 minutes.
But wait.
If you crank it up to 350°F, which a lot of home cooks prefer for crispier skin, you’re looking at closer to 13 minutes per pound. That brings your total time down to roughly 2 hours and 45 minutes to 3 hours. It’s a delicate balance. You want the skin to look like a sunset, but you don't want the breast meat to turn into sawdust while you wait for the dark meat to reach safety.
Why Stuffing Changes Everything
If you decided to shove a bread-based mixture into the cavity, you've just turned your turkey into a heat sink. It’s no longer just a bird; it’s a dense projectile. For a stuffed 13-pounder, you need to add at least 30 to 45 minutes to your total time.

The danger here is real.
The stuffing has to reach 165°F to be safe because it’s soaking up all those raw turkey juices. Often, by the time the stuffing is safe, the breast meat is 180°F and practically inedible. This is why many chefs, like Alton Brown or J. Kenji López-Alt, advocate for cooking the stuffing in a separate casserole dish. It's just safer and tastes better.
How Long to Cook 13 lb Turkey in Oven if it’s Still Kinda Frozen?
Don't do it. Just don't.
If you realized this morning that the center of your bird is still a block of ice, your cooking times are going to go completely out the window. Cooking a partially frozen turkey can take 50% longer than a thawed one. For our 13-pound subject, that could mean five hours in the oven. The outside will be burnt to a crisp before the inside even thinks about getting warm.
If you're in a pinch, use the cold-water thaw method. Submerge the bird in its original wrapper in cold tap water, changing the water every 30 minutes. For a 13-pound bird, this takes about 6.5 hours. It’s a pain, but it’s better than serving a "turkey popsicle" to your in-laws.
The Impact of Oven Type
Is your oven convection or conventional? This matters.

Convection ovens circulate hot air with a fan. This speeds things up significantly. If you’re using convection, you can usually drop the temperature by 25 degrees or expect the bird to cook about 25% faster. A 13-pound turkey in a convection oven might be done in a little over 2 hours. Keep a very close eye on it.
The Only Tool That Actually Matters
Forget the clock. Seriously.
The clock is a guide, not a ruler. The only way to truly know how long to cook 13 lb turkey in oven is by using a high-quality meat thermometer. You want an instant-read digital one if possible.
You are looking for two specific numbers:
- 165°F in the thickest part of the breast.
- 175°F in the thickest part of the thigh (avoiding the bone).
The thigh takes longer because it’s denser and has more connective tissue. If you pull the bird when the breast hits 160°F, carry-over cooking will usually bring it up to that final 165°F while it rests on the counter.
High Heat Roasting: The 450°F Method
Some people swear by the high-heat method. You blast the 13-pound turkey at 450°F for the entire duration. This is risky. You’ll get incredible skin, but you have to be vigilant. Usually, a bird this size will cook in about 1 hour and 45 minutes to 2 hours at that heat.

However, you almost certainly have to shield the breast with foil halfway through so it doesn't char. It’s a high-octane way to cook, and honestly, if it’s your first time, stick to 325°F or 350°F. It's much more forgiving.
The Resting Period
This is non-negotiable.
Once that thermometer hits the target, take the turkey out. Put it on a carving board. Tent it loosely with foil. Now, walk away. For at least 30 minutes.
The juices need time to redistribute. If you cut into it immediately, all that moisture you worked so hard to keep inside will just pour out onto the board, leaving you with dry meat. A 13-pound turkey has enough mass to stay piping hot for nearly an hour, so don't worry about it getting cold.
Common Myths That Waste Your Time
- Basting: Opening the oven every 20 minutes to pour juice over the skin does nothing for moisture. The skin is waterproof. All you’re doing is letting the heat out and making the cooking process take longer.
- The Pop-up Timer: Those little plastic things that come in the turkey? Throw them away. They are notoriously unreliable and often don't pop until the bird is way past 180°F.
- Covering with a Lid: If you roast your turkey in a covered pan, you’re steaming it, not roasting it. You won’t get crispy skin, and the texture will be more like deli meat.
Actionable Summary for Your 13 lb Turkey
- Thaw it completely. Allow 3 days in the fridge.
- Preheat to 325°F. This is the safest, most consistent temp.
- Estimate 3 to 3.5 hours. Start checking the temperature at the 2.5-hour mark.
- Target 165°F. Use a thermometer in the breast and thigh.
- Rest for 30-45 minutes. This is the difference between "okay" and "amazing."
To make sure your bird is ready, verify your oven's actual temperature with an internal oven thermometer today. Most ovens are off by 10 to 15 degrees, which can drastically change your timing. Once you've confirmed the temp, prep your dry brine at least 24 hours in advance to ensure the skin crisps up perfectly.
