Ask guests about food allergies early, prevent cross-contact in the kitchen, and label dishes at the table. A short conversation and a few extra pans do more than a complicated menu. Keep a simple backup dish that is safe for the most serious restriction at your dinner. See the Thanksgiving guide and Thanksgiving mains, diets and leftovers. This is not a second general hosting guide; it is the allergy-and-diet plan that sits next to recipes like gluten-free gravy and dairy-free mashed potatoes.
Ask first, then plan one safe plate
About two weeks ahead, ask each guest about allergies, intolerances, and foods they must avoid. Serious allergies, such as peanuts, tree nuts, wheat, milk, eggs, soy, fish, or sesame, need more care than a preference. If a guest has a severe allergy, consider making one main and two sides that are fully free of that allergen, cooked in clean pans, and served with their own utensils. A guest may also prefer to bring a safe dish they already trust. For gluten, start with a clean turkey, gluten-free gravy, and a starch that was never near breadcrumbs. For dairy, butter in mashed potatoes and rolls is a common surprise.
Stop cross-contact in the kitchen and at the table
Wash hands, boards, knives, and pans before you cook the allergen-free food, and cook it first if you can, or in a separate area. Do not use the same spoon to taste and then stir a safe dish. At the table, give every dish its own serving utensil and a short label: “contains milk,” “contains wheat,” or “no nuts.” Set the safest dishes slightly apart so a shared spoon is less likely. If you also have vegan or vegetarian guests, vegan gravy and a mushroom Wellington can fill that plate without trying to make every classic dish work for everyone.
Have a backup, and do not downplay a serious allergy
Set aside one clearly safe dish, such as a plain roasted vegetable or a simple rice or potato cooked in a clean pan, even if you think you have covered every recipe. For a severe allergy, it is better to skip a risky ingredient in a shared dish than to hide a small amount and hope no one notices. Do not use “a little bit should be fine” as a plan. If you are unsure about a packaged ingredient, read the label the day you shop, not as dinner starts. After the meal, store leftovers in labeled containers so the safe food does not get mixed with the rest in the refrigerator.
Frequently asked questions
When should I ask guests about food allergies?
Ask when you send the invitation, or at least one to two weeks ahead, so you have time to plan a safe main and a couple of sides.
What is cross-contact?
Cross-contact is when an allergen moves from one food to another on a shared cutting board, pan, knife, or serving spoon, even if you cannot see it.
Should a guest with allergies bring their own food?
It can be a good backup, especially for a severe allergy. Even then, it helps if the host makes one clearly labeled safe dish and keeps it separate.
