Most Thanksgiving sides can be made gluten-free, but four of them hide wheat where you wouldn’t look. The gravy, the stuffing, the green bean casserole and even the turkey’s prep can all carry it. Here’s what two hospital dietitians flag, what they suggest instead, and how to keep your gluten-free dishes safe on the table.
We’re a recipe site, not a medical one, and we haven’t tested any dish here. If a guest has celiac disease, ask them what they can eat before you plan the menu!
Which gluten free Thanksgiving side dishes need a label check?
The usual suspects are the dishes built on a thickener, a soup or bread. News-Medical (November 2019) passes along advice from Macy Mears, a registered dietitian at University of Chicago Medicine. Nationwide Children’s Hospital (updated November 2025) gives similar advice from dietitian Mary Kay Sharrett.
| Dish | What the dietitians flag | The swap they suggest |
|---|---|---|
| Gravy | Flour is a common thickener, and packets often contain barley or wheat, such as yeast extract | Cornstarch; check the broth base or mix. Nationwide Children’s suggests meat drippings thickened with cornstarch |
| Stuffing | Regular bread or flour-based cornbread. Stuffing cooked inside the bird can contaminate even the meat on the outside | A gluten-free mix, or a wild rice stuffing with fruit and nuts. Cook it in a separate dish |
| Green bean casserole | The cream of mushroom soup usually contains wheat, and so do breaded onion rings | Homemade or store-bought gluten-free soup, and onions coated in a gluten-free flour mix. Some stores sell gluten-free fried onions year-round |
| Mashed potatoes | Added broth and spices may contain gluten | Read the ingredient list |
| Turkey | The bird is naturally gluten-free, but self-basting, brined, pre-stuffed, injected or sauce-basted ones can add it | Check the label; for deep-frying, the oil must not have cooked gluten foods |
| Pie | Fillings such as pecan, pumpkin and fruit are usually gluten-free | Only the crust typically needs changing |
The pattern is simple. Dishes that are mostly vegetables, potatoes or plain meat start out fine, and the trouble comes from the can, the packet or the breadcrumbs. Check those labels first.
What can you serve without much worry?
The plainer the dish, the fewer labels to read, so start with potatoes, roasted vegetables and plain green beans before you reach for anything canned, boxed or packeted.
One commenter in an r/Cooking thread (September 2026), who says they’re married to a gluten-free person, lists “mashed potatoes, sweet potato casserole, roasted Brussels Sprouts, honey roasted carrots, green beans” and says King Arthur makes a gluten-free cornbread mix they like. That’s one person’s list, not a rule, so do you trust it for your guest? Mashed potatoes still need the broth check above, and any packaged mix needs its own label read.
If you’d rather start from recipes, Dish by Dish (December 2025) collects 49 recipes it labels gluten-free. They include gluten-free versions of green bean casserole, cornbread stuffing, turkey gravy, crispy fried onions and cream of mushroom soup, so the gravy, stuffing and green bean casserole swaps from the table are all covered there. We haven’t made any of them.
For more ideas, our Thanksgiving side dishes ranked and vegetable sides sorted by oven space pages cover the full spread, and our gluten-free dinner recipes list is handy for the days around it. Check each dish’s own ingredient list against the table, since those pages aren’t written for a gluten-free table. Dessert counts too! See our Thanksgiving dessert ideas.
How do you avoid cross-contact?
Keep gluten away from the gluten-free dishes while you cook and while you serve. Nationwide Children’s says it’s best to make the gluten-free dishes first, before the gluten-containing ingredients come out, and to keep prep areas free of crumbs. It also warns that spreadable items like butter or mustard can pick up breadcrumbs.
At the table, News-Medical says to serve yourself first and keep gluten-free dishes in a separate area, so a spoon from a gluten dish never ends up in a gluten-free one. Nationwide Children’s adds separate utensils at a buffet.
How strict you need to be depends on the guest. A commenter in an r/glutenfree thread (October 2022) put it bluntly:
“Be sure to clean your kitchen scrupulously. Your plan of entirely gluten free is the best plan, arguably the only one with celiac. No wheat flour for several days prior, it gets airborne.”
Another commenter in the r/Cooking thread said that for someone at the extreme end, cooking at home may not be safe “because you won’t be able to avoid cross-contamination.” So ask your guest how they handle it.
Gluten-free Thanksgiving questions people ask
Is turkey gluten-free?
The bird is, per News-Medical. The risk is in the prep: self-basting, brined, pre-stuffed, injected or sauce-basted turkeys can add gluten, so read the label.
Can you use canned cream of mushroom soup?
Only if the label says gluten-free. Nationwide Children’s says the traditional soup usually contains wheat, but gluten-free versions exist.
How do you thicken gravy without flour?
Both dietitians point to cornstarch, and to checking the broth or seasoning for gluten.
