Which Size Roasting Pan Fits a 20 Lb Turkey?

A 20 lb turkey needs a large roasting pan, at least 16 by 13 inches across the inside floor, with sides about 2 to 3 inches tall. If your oven can take it, an 18 by 13 inch pan is the more comfortable fit.

For most people, that’s all you need to know. The rest of this post covers the things that go wrong on Thanksgiving morning, like handles that keep the oven door from closing and foil pans that fold under the weight. Updated October 20, 2026.

What size roasting pan do you need for a 20 lb turkey?

You need a pan with an inside floor of at least 16 by 13 inches. A turkey this size is usually about 15 to 16 inches long and 11 to 12 inches wide, though the breed and the way it’s trussed change that a little. You want about an inch of space on each side so hot air reaches the thighs and you can get a baster in.

Pans sold as “large” are usually rated for birds up to about 20 to 25 pounds. A 20 lb turkey is near the top of what a 16 inch pan holds comfortably, so check the rating on the box. If it says “up to 18 pounds,” get the next size up.

How do you measure a roasting pan correctly?

Measure the flat inside floor of the pan, not the size printed on the box. Many listings measure from the tip of one handle to the tip of the other, so a pan sold as 16 inches may only give you 13 or 14 inches of usable floor. The sides also slope outward, which makes the rim bigger than the floor.

The easiest test is to set the wrapped, still-frozen turkey in the pan a few days early. If any part of it touches the sides or hangs over the edge, the pan is too small. It takes ten seconds, and you won’t find out at 6 a.m. on the day.

Will an 18 inch pan fit in your oven?

Most standard 30 inch ranges can take an 18 inch roasting pan, but the handles are what usually cause trouble. Measure your oven’s inside width and depth, then leave an inch or two of space all around the pan so air can move. Upright handles can hit the door or the back wall before the pan itself does.

Height is the other problem. A 20 lb turkey on a rack can stand 10 inches or more above the oven rack, so move the rack to its lowest position before you heat the oven. Apartment ranges that are 24 inches wide and some wall ovens are tighter, so renters should measure before they buy a big pan.

How deep should the roasting pan be?

Sides about 2 to 3 inches tall work best. Sides of 4 inches or more block the heat from the lower part of the bird, and the thighs come out pale and steamed instead of browned. Very shallow pans have the opposite problem, because the drippings slosh over the edge when you move the pan.

The material matters too. A heavy stainless steel or tri-ply pan can go straight onto a burner so you can make gravy in it, and it won’t warp under the weight. Dark nonstick pans brown the drippings faster and can scorch them during a long roast.

Plan for the weight. With the bird, the pan, and the drippings, you can be lifting more than 25 pounds of very hot food, so sturdy handles and good grips matter. If your hands don’t grip well, these silicone oven mitts for sore or arthritic hands make the lift a lot safer.

Can you use a disposable foil pan for a 20 lb turkey?

Yes, but always put a rimmed sheet pan underneath it. Foil pans bend when you lift them with this much weight inside, and hot fat can spill onto your arms or the oven floor. Buy one marked heavy duty and rated for 20 pounds or more.

You can’t make gravy on the stove in a foil pan, so pour the drippings into a saucepan instead. If you only roast one turkey a year, a foil pan on top of a sheet pan you already own is a perfectly good choice. A good roasting pan is worth buying if you’ll also use it for roasts or big trays of vegetables through the winter.

What size electric roaster fits a 20 lb turkey?

An 18 quart electric roaster is the usual size, and most are rated for turkeys up to about 20 to 22 pounds. Check the rating on the box, because a 20 lb bird is close to the limit and a tall one can touch the lid. If it touches, that spot won’t brown and may stick.

Electric roasters keep the heat and moisture in, so the meat stays juicy but the skin doesn’t crisp the way it does in an oven. The big advantage is that your oven stays free for the sides and pies. Many cooks put the roasted bird under the oven broiler for a few minutes at the end to crisp the skin.

What size pan for a spatchcocked 20 lb turkey?

A spatchcocked 20 lb turkey needs a rimmed half sheet pan, which is about 18 by 13 inches, with a wire rack inside it. Once the bird is flattened it’s much wider, and a bird this big can still hang over the edges of a half sheet pan. A larger three-quarter sheet pan solves that, but only if your oven is deep enough for one.

Here’s the honest part: spatchcocking a 20 lb turkey is hard work. The backbone on a bird this size is thick, and ordinary kitchen shears have trouble with it. Lots of cooks roast two 10 to 12 lb turkeys side by side instead, which also fixes the pan size problem.

Do you need a roasting rack?

A rack helps, but you don’t need one. It lifts the bird so hot air reaches the underside and the bottom doesn’t sit in its own juices. Most roasting pans come with a flat rack, and a V-rack holds the bird more firmly.

The free option works fine: put the turkey on a layer of thick onion rounds and carrot chunks. The vegetables lift the bird and add flavor to the drippings for gravy. Skip buying a rack just for one meal.

Measure your pan and your oven this week, while the turkey is still in the freezer and the stores still have good pans in stock. If you find you do need a bigger pan, check our current deals page before you pay full price for something you’ll use once a year.

If you’re hosting, there’s other prep to do before the guests arrive. Get the Halloween fake blood out of your carpet first, and if the rooms smell stale, here’s why a house can smell musty once the heat comes on. For a cold guest room, see whether a heated mattress pad uses much electricity before you plug one in.
