Thanksgiving Menu for Food Allergies, Low-FODMAP and Diabetes

Your sister has a dairy allergy, your father-in-law has type 2 diabetes, a cousin is low-FODMAP, and one guest can't have nuts. Here is one Thanksgiving dinner they can all eat, plus the questions to ask before you shop.

Thanksgiving is the hardest meal of the year to cook around dietary needs. It is one big meal, it runs on tradition, and almost every classic dish hides something. Wheat in the stuffing and the gravy. Butter and cream in the potatoes. Onion and garlic in nearly everything. Pecans on the pie and marshmallows on the sweet potatoes.

The answer is the same one that works on a weeknight: cook the shared dishes to the strictest need at the table, then put the extras in their own bowls so each guest can add what they eat. You end up with one dinner, a few extra bowls, and no one eating rolls for dinner.

Ask before you shop

Most of the stress on Thanksgiving comes from finding out on Wednesday night. A short message to each guest a week or two ahead fixes that. Ask:

Is it an allergy, an intolerance, or a preference? A severe allergy means separate pans, separate spoons, and reading every label. A preference means you can relax.
What exactly is off the table? "Gluten-free" and "no wheat" overlap but aren't identical. "Low-FODMAP" usually means no onion, no garlic, no wheat bread, and limited lactose, but people in the reintroduction phase may handle some of those.
For anyone managing diabetes: would they like the starches served on the side so they can portion their own? Most people would.
Is anyone bringing a dish? If so, send them the list of what to leave out, or ask them to bring the label.

Write the answers down in one place, one line per person. That list decides the base of every shared dish.

Where the problems hide in a classic Thanksgiving

Dish	What usually hides in it	The swap
Turkey	Stuffing cooked inside (wheat), butter rubs (dairy), and pre-brined or self-basting birds with added broth or flavorings	Cook the stuffing in its own dish. Rub with olive oil or garlic-infused oil and herbs. Read the label on the bird.
Gravy	Flour roux (wheat), boxed broth with onion and garlic	Thicken with cornstarch. Use broth made without onion or garlic.
Stuffing	Wheat bread, onion, celery, eggs, sometimes oysters or sausage	Gluten-free bread, garlic-infused oil, scallion greens, sage. Check the sausage label or leave it out.
Mashed potatoes	Butter, cream, milk, garlic	Mash with olive oil and some of the cooking water. Butter goes in a dish on the side.
Green bean casserole	Canned cream of mushroom soup (wheat, dairy), fried onions	Roasted green beans with lemon. Toasted almonds in a separate bowl.
Sweet potatoes	Marshmallows, brown sugar, pecans, butter	Roast plain with oil and salt. Maple syrup and nuts on the side.
Rolls	Wheat, dairy, eggs, sometimes sesame	Buy a separate gluten-free option and keep it in its own basket.
Pie	Wheat crust, butter, eggs, milk, pecans	A crustless pumpkin pie, or a gluten-free crust. Have one dessert that fits the strictest guest.

A Thanksgiving menu everyone at the table can eat

This menu is built for the table in the opening paragraph: dairy allergy, nut allergy, low-FODMAP, and diabetes. Every dish below works for all four as written. The extras in brackets go in their own bowls.

Herb-roasted turkey. Olive oil, salt, pepper, sage, thyme and rosemary. Nothing inside the bird. Check the label for added broth or flavorings.
Cornstarch gravy. Pan drippings, broth made without onion or garlic, thickened with a cornstarch slurry.
Gluten-free sage stuffing, baked in its own dish. Gluten-free bread cubes, garlic-infused oil, carrots, scallion greens, sage, and broth.
Olive oil mashed potatoes. [Butter on the side.]
Roasted green beans with lemon. [Toasted almonds on the side, well away from the guest with the nut allergy.]
Roasted sweet potatoes with oil and salt. [Maple syrup on the side.]
Simple green salad with cucumber, carrot, and an olive oil and lemon dressing.
Cranberry sauce made from fresh cranberries, orange zest, and maple syrup.
Rolls in two baskets: regular, and a dairy-free gluten-free option.
Dessert: crustless pumpkin pie made with a dairy-free milk that isn't nut-based, and a bowl of berries.

A few notes on the menu:

Low-FODMAP guests: garlic-infused oil carries the garlic flavor without the part that causes trouble, and scallion greens and chives stand in for onion. Sweet potato, cranberry sauce and pumpkin are fine in small servings. The Monash University FODMAP app lists serving sizes if your guest wants to check.
Guests managing diabetes: with the potatoes, stuffing, sweet potatoes and rolls all in their own dishes, they can build a plate around turkey, green beans and salad and add the starches they want. Maple syrup on the side keeps the sweet potatoes plain for them.
Dairy allergy: butter shows up only in side dishes, and the pie uses a dairy-free milk. Check the gluten-free bread and rolls too, since some contain milk.
Nut allergy: nuts appear only as a topping in their own bowl. If the allergy is severe, leave them out of the house entirely.

Keep it safe on the day

Cook the allergy-safe dishes first, before flour, butter or nuts come out.
One spoon per dish, and it stays in that dish.
Label the table. A folded card in front of each dish naming what's in it saves a lot of questions.
Let the guest with the most serious allergy serve themselves first, before other spoons have wandered.
Keep the labels. Hold on to the packaging from the broth, the bread and the stuffing mix until dinner is over, so anyone can check.

If more than one person in your own house has a food allergy, the same habits apply every week. Meal planning when more than one person has a food allergy covers the everyday version, and one dinner, different diets walks through a full week of base-and-toppings dinners.

Planning the rest of the week

Thanksgiving is one dinner. The nights around it still need planning, and they need to fit everyone's needs too.

Eat Roostly plans the week for you. Each member of the household gets their own profile with their own allergies, intolerances and diet, and every weekly plan is filtered against all of them at once. Filtering is best-effort and free on every plan. For the details, see food allergy meal planning, low-FODMAP meal planning, and diabetes-friendly meal planning.

On the Home Chef and Family Table plans, you can set a headcount and an occasion for any night. Mark Thursday as Thanksgiving for 12, and the planner picks a holiday centerpiece, sizes the recipe for 12, and buys for 12 on the shopping list, while the other nights stay sized for your household.

Cooking for different needs all year? → Set each person's allergies and diet once and get a week of dinners that fits all of them.

Allergy and diet filtering is best-effort: always verify ingredients and packaging yourself, especially where a serious allergy is involved.
