Most of us cook Thanksgiving dinner in one oven. The turkey wants it for hours, the stuffing and sweet potato casserole want it at a different temperature, and the rolls want it right at the end. The good news: with a little make-ahead work and a plan for the turkey’s rest, one oven is plenty. Here’s how to time every dish so everything lands on the table hot, together, on Thursday, November 26.
The short version
- Do the day-before work. Cranberry sauce, gravy and mashed potatoes can be made ahead, and casseroles can be assembled and chilled.
- The turkey gets the oven first. Roast it at 325°F until it reads 165°F in the thigh, wing and thickest part of the breast.
- The rest is your oven window. The turkey needs at least 20 minutes to rest, and tented with foil it stays nicely warm for 30 to 45 minutes. That’s when the casseroles bake.
- Move everything else off the oven. Reheat mashed potatoes and gravy on the stovetop or in the microwave, then keep them hot in a slow cooker.
- Reheat to 165°F, hold at 140°F or above, and get leftovers into the fridge within 2 hours.
The day before: make the oven’s job smaller
Every dish you finish on Wednesday is one less thing fighting for the oven on Thursday. Here’s what travels well:
| Dish | How far ahead | On the day |
|---|---|---|
| Cranberry sauce | Up to a week | Serve cold, nothing to heat |
| Turkey gravy | Days ahead, or frozen | Stovetop, brought to a rolling boil |
| Mashed potatoes | Up to 2 days | Stovetop or microwave to 165°F |
| Sausage and herb stuffing | Assemble up to 24 hours ahead | Bake while the turkey rests |
| Sweet potato casserole | Assemble up to 1 day ahead | Bake while the turkey rests |
| Pies | Bake Wednesday | Serve at room temperature or chilled |
Pies are the easy win: bake them Wednesday while the oven is free. Pumpkin and other custard pies go in the fridge once they cool. And if your turkey is still frozen, it should already be in the fridge by now. Check our turkey thawing guide for the date to start.
Thanksgiving morning: the turkey goes first
The turkey is the one dish that truly needs the oven for hours, so plan the rest of the day around it. The USDA’s roasting times at 325°F for an unstuffed bird are a good starting point:
| Turkey weight (unstuffed) | Approximate time at 325°F |
|---|---|
| 8 to 12 lb | 2¾ to 3 hours |
| 12 to 14 lb | 3 to 3¾ hours |
| 14 to 18 lb | 3¾ to 4¼ hours |
| 18 to 20 lb | 4¼ to 4½ hours |
| 20 to 24 lb | 4½ to 5 hours |
These times are approximate. A thermometer, not the clock, tells you when it’s done: 165°F in the innermost part of the thigh and wing and the thickest part of the breast. Baking the stuffing in its own dish, rather than in the bird, also makes the turkey cook more evenly, and it frees up that dish for the rest window.
The rest window: when the casseroles bake
Here’s the trick that makes one oven work. Once the turkey comes out, it needs to rest before carving. The USDA recommends at least 20 minutes so the juices set, and a big bird loosely tented with foil stays warm for 30 to 45 minutes. That’s your window.
As soon as the turkey is out, turn the oven up to 350°F and slide in the casseroles you assembled the day before. Our sweet potato casserole bakes in about 30 to 35 minutes. A stuffing straight from the fridge may need longer, so give it a head start on a lower rack during the turkey’s last stretch, then finish it at 350°F. Stuffing is done when the center reaches 165°F. If there’s room at the end, warm the rolls for the last few minutes.
Off the oven: stovetop, microwave and slow cooker
Anything that doesn’t need a crisp top can skip the oven entirely.
- Mashed potatoes: reheat them on the stovetop over low heat, stirring and adding a splash of milk or cream, or covered in the microwave, stirring now and then, until they reach 165°F. Then move them to a preheated slow cooker set to warm to hold them for serving.
- Gravy: reheat it in a saucepan and bring it to a rolling boil, then whisk in the skimmed drippings from the roasting pan.
- Green beans and other vegetables: a skillet or the microwave works while the oven is busy.
One food safety note on slow cookers: they’re great for keeping food hot, but the USDA doesn’t recommend using one to reheat cooked food, because it can take too long to get hot. Reheat on the stove, in the microwave or in the oven to 165°F first, then hold it in the slow cooker.
A sample one-oven timeline
Here’s how it fits together for a 12 to 14 lb unstuffed turkey with dinner at 3:00 PM. Slide the times earlier or later for your bird and your dinner hour.
| Time | What happens |
|---|---|
| 10:00 AM | Heat the oven to 325°F. Pull the turkey from the fridge and get it in the roasting pan. |
| 10:30 AM | Turkey in the oven (about 3 to 3¾ hours). |
| 1:00 PM | Start checking the turkey’s temperature every 20 to 30 minutes. |
| About 1:45 PM | Stuffing onto a lower rack if it needs extra time. |
| About 2:00 PM | Turkey reads 165°F. Out it comes, tented with foil. Oven up to 350°F, casseroles in. |
| 2:00 PM | Reheat the mashed potatoes to 165°F, then hold them in a warm slow cooker. |
| 2:20 PM | Gravy on the stove to a rolling boil, then whisk in the drippings. |
| 2:35 PM | Casseroles out once the stuffing’s center hits 165°F. Rolls in for a few minutes. Carve the turkey. |
| 3:00 PM | Dinner. |
Keeping it hot, and handling leftovers
Once dinner is served, the same food safety basics apply all afternoon:
- Hot food stays at 140°F or warmer. Slow cookers, warming trays and chafing dishes all work for a buffet.
- The 2-hour rule. Turkey, stuffing, gravy and other perishable food shouldn’t sit at room temperature for more than 2 hours. Bacteria grow quickly between 40°F and 140°F.
- Cool leftovers fast. Slice the breast meat, divide everything into shallow covered containers and refrigerate. Use them within 3 to 4 days, or freeze them.
- Reheat leftovers to 165°F, and bring gravy back to a rolling boil.
Keep your whole Thanksgiving plan in one place
A one-oven Thanksgiving is really just a good plan, and the plan is easier when every recipe is in one spot: the gravy, the stuffing, the sweet potatoes and Grandma’s pie. Keep the Sauce is the family recipe box app for iPhone, iPad and Android. Save recipes from anywhere, scale them for a crowd and plan the week’s menu, so the whole family’s recipes are right where you need them on Thursday.
