Questions to Ask a Restaurant Before Ordering With a Nut Allergy

Before ordering with a nut allergy, ask where your allergens are used, what's in every part of your dish, and how the kitchen handles shared equipment and preparation areas. Tell staff exactly which allergies you have, and ask them to confirm your order with the kitchen before you commit to it.

You don't need to deliver a speech. You need specific answers about the food you're considering and the way it'll be prepared. The questions below give you language to use at the table, including when your server needs to go back and check.

How do I tell a restaurant about my nut allergy?

Start with your allergy before discussing the order. Name each allergen you need to avoid instead of leaving staff to interpret “nuts.” Use the avoidance instructions you've agreed on with your allergist.

For example, if it describes your allergies, say:

“I have a peanut and cashew allergy. Could you check ingredients and preparation with the kitchen before I order?”

If you're avoiding all tree nuts, say that explicitly. If you're avoiding particular ones, name them. Don't shorten your explanation because the server looks busy.

Clear communication about the foods you're allergic to is a central recommendation in CU Anschutz's guidance on eating at restaurants.

Picture joining a party of six as everyone starts ordering appetizers. Ask for the allergy conversation before agreeing to a shared starter. You can say, “Please give me a moment to check my order with our server.” That keeps the conversation focused without requiring everyone else to explain your needs for you.

1. Are peanuts or tree nuts used anywhere in the kitchen?

Ask about the kitchen as a whole before narrowing the conversation to one dish:

“Where do you use peanuts or tree nuts, including in sauces, oils, dressings, and garnishes?”

Then repeat the particular allergens that apply to you. You're asking staff to look beyond a visible topping.

Allergens aren't always apparent from looking at food. The American Academy of Allergy, Asthma & Immunology advises diners to ask about ingredients, including those in sauces and prepared components. See its restaurant dining guidance.

A useful response identifies where your allergens are used and what needs further checking. “We don't put nuts on that” leaves the rest of the recipe unanswered.

Try this follow-up:

“Thanks. Could you also check whether they're included in the dressing or anything used to prepare it?”

If the server says they don't know, give them time to find out. Don't treat an initial guess as a kitchen confirmation.

2. Can you check every ingredient in the dish I want?

Once you've picked a possible order, ask about its complete preparation:

“Could the kitchen check this dish's ingredients, including its sauce, marinade, cooking oil, and garnish?”

Ask staff to check the current recipe and the ingredient information for anything bought ready-made. Don't ask them to rely on what they remember from a previous shift.

For a hypothetical chicken-and-salad order, make the request concrete:

Part of the order	Follow-up question
Chicken	“What's in the marinade, and which oil is used?”
Salad	“Could you check the dressing and every topping?”
Side dish	“Does this come with a sauce or finishing garnish?”
Proposed substitution	“Could you check the replacement's ingredients too?”

These questions follow the Allergy & Asthma Network's advice to ask about ingredients and preparation.

If the restaurant proposes leaving something off, ask whether it's added individually or already mixed into a prepared component. “No dressing” needs a different kitchen answer if the salad has already been dressed.

When staff can't verify a component, don't fill that gap with an assumption. Ask about a different option whose ingredients they can check.

Ingredient checking is only part of the conversation. Cross-contact happens when an allergen's proteins transfer to another food through preparation or handling. Even trace amounts can cause a serious reaction, which is why allergen handling guidance addresses preparation practices as well as recipes.

Ask about the equipment used for your actual order:

“Will this use a fryer, grill, cutting board, or utensils that also handle peanuts or the tree nuts I've named?”

If the answer is yes, ask what the kitchen can change. “We can leave off the topping” doesn't answer a question about shared equipment.

For example, suppose you're considering fries. Ask which other foods use that fryer and whether any contain your allergens. If staff suggest another side, check its preparation too.

You don't have to audit the entire kitchen. Keep bringing the answer back to your plate: which equipment will it touch, and what precautions will staff take? The restaurant cross-contact checklist offers more context for that conversation.

4. Is there a separate preparation area or equipment for my order?

Follow the shared-equipment question with a practical one:

“Can the kitchen use a separate preparation area and equipment for my order? If equipment is shared, how will it be cleaned before use?”

Ask what “separate” means for this particular dish. Does the answer cover the preparation surface, the pan, and the utensils used to serve it?

CU Anschutz's restaurant guidance specifically emphasizes clean utensils and avoiding transfer from previously prepared foods. A recipe that doesn't include your allergen still leaves handling questions to resolve.

For example, if a server offers a separate pan, follow up with, “Could you check the utensils and prep surface too?”

Listen for an explanation of what the kitchen can actually do during this service. A promise without details doesn't answer the question. Neither does the presence of separate equipment remove the need to check ingredients and communicate your allergy.

5. Will the chef and kitchen staff receive my allergy information?

Ask how your allergy will reach the people preparing the order:

“Will you mark my allergies on the ticket and confirm the preparation directly with the kitchen?”

Then ask the server to return with the answer before placing the order. The Allergy & Asthma Network recommends communicating with restaurant staff and passing written allergy information to the kitchen.

Here's an illustrative exchange:

Diner: “I'm allergic to peanuts and cashews. Could you check the chicken, dressing, and equipment?”

Server: “I'll check with the kitchen.”

Diner: “Thank you. Please let me know what they confirm before putting my order through.”

That gives the server a clear next step. It also avoids turning “I'll check” into an assumed answer.

When the food arrives, confirm that it's the order prepared with your allergy instructions. If someone else brings it, ask them to check with your server rather than guessing from the plate's appearance.

The guide to handling guest allergy questions explains the staff side of this conversation.

When should I pause my order or leave a restaurant?

Pause when the answer doesn't address what you asked. Common examples include “probably,” “it's only a little,” or “we'll just take the nuts off.” Ask for the missing information once more, clearly.

You could say:

“I still need the kitchen to confirm the ingredients and preparation. If that isn't possible, I won't order this.”

If staff can't resolve your concern, you don't have to eat the food. CU Anschutz's advice supports declining food when allergy concerns aren't adequately addressed.

The same applies if the arriving dish doesn't match the discussion. Stop and ask staff to investigate. Don't let your party's schedule decide whether you accept an unexplained change.

You can be courteous and direct: “Thank you for checking. This won't work for my allergy needs.” An honest statement that the kitchen can't accommodate your request gives you information you can act on.

What should I bring when dining out with a nut allergy?

Bring at least two epinephrine auto-injectors and a copy of your food allergy emergency action plan. Choosing a quieter service time may also give staff more time for the conversation. Both preparation and off-peak dining are covered in AAAAI's dining recommendations.

A written chef card gives staff your specific allergies in a form they can take to the kitchen. Hand it over while explaining your needs, and ask for confirmation after it's been read.

At restaurants that publish menus on Can I Dine?™, guests can scan the restaurant's QR code at the table and filter by allergy in 10 languages. It organizes restaurant-provided information; you still need to tell staff about your allergies, and staff must confirm your order with the kitchen. The free allergy chef card in 10 languages can help you put those same needs in writing.

Keep the final question simple: “Has the kitchen confirmed the ingredients and preparation we discussed?”

Frequently asked questions

What should I ask first when ordering with a nut allergy?

Start by naming your specific allergies and asking staff to confirm ingredients and preparation with the kitchen. For example: “I have a peanut and cashew allergy. Could you check this dish before I order?” Then ask about sauces, cooking oils, garnishes, and shared equipment. Don't assume that a request to remove a topping covers the whole order.

Should I say which nuts I'm allergic to?

Yes. Name the specific allergens you need to avoid, following your allergist's instructions. Don't leave staff to interpret the word “nuts.” If you're avoiding peanuts and all tree nuts, say both. If your instructions name particular tree nuts, list them clearly and ask staff to repeat that information to the kitchen.

What should I ask about shared fryers and grills?

Ask whether the equipment used for your order also handles your allergens, then ask what preparation changes the kitchen can make. Include utensils and cutting boards in that discussion. Don't stop at checking the recipe. [AAAAI recommends asking about shared equipment and utensils](https://www.aaaai.org/tools-for-the-public/conditions-library/allergies/dining) when discussing food allergy needs with restaurant staff.

What if restaurant staff can't confirm a dish's ingredients?

Don't order that dish based on a guess. Ask whether the kitchen can verify another option, including its preparation. If your concern remains unresolved, you can decline the food or leave. [CU Anschutz's restaurant guidance](https://news.cuanschutz.edu/department-of-medicine/food-allergies-eating-restaurants) supports not eating food when allergy concerns haven't been adequately addressed. You don't need to accept uncertainty because others are ready to order.

Does an allergy chef card replace talking to my server?

No. Use a chef card alongside a direct conversation about your allergies. Ask the server to share it with the kitchen and return with confirmation about your chosen order. The [Allergy & Asthma Network recommends chef cards as part of restaurant communication](https://allergyasthmanetwork.org/food-allergies/). A written list doesn't tell you how today's dish will be prepared.
