Eating out with a peanut allergy

Eating out with a peanut allergy comes down to three questions: what thickens the sauce, what oil the kitchen fries in, and whether desserts share equipment with nut work — peanut is a legume, not a tree nut, and it shows up far outside the nut aisle.

What EU labelling covers

Annex II of EU Regulation 1169/2011 lists "Peanuts" among the 14 allergens that must always be declared. Any business selling food in the EU — including restaurants selling food loose and unpackaged — must be able to tell you whether this allergen is an ingredient in what it serves. That duty covers declared ingredients only, not cross-contact.

Hidden sources of peanut

Where it appears without being named in the dish description.

  • Satay, mole, korma and several ready-made curry pastes are thickened or enriched with ground peanut.
  • Chilli, barbecue and some Sichuan cold-noodle dressings use peanut butter as a thickener.
  • Egg rolls and dumplings are occasionally sealed with peanut paste.
  • Peanut flour appears in some vegan burgers, protein bars and meat-free 'chicken' products.
  • Cold-pressed, expelled or 'gourmet' peanut oil retains protein; highly refined peanut oil does not, and kitchens rarely know which grade they have.
  • Bakery marzipan substitutes and cheap praline fillings sometimes use peanut instead of almond.

How it reaches a dish that does not contain it

Cross-contact is a kitchen-process problem, not a recipe problem, so these are the questions a recipe cannot answer.

  • Shared fryer oil: peanut-coated items fried in the same oil as chips transfer protein to everything else in the basket.
  • Ice-cream scoops and bakery tongs carry residue between tubs and trays.
  • Buffets and salad bars, where a shared spoon moves toppings between bowls.
  • Woks and grills wiped rather than washed between orders.
  • Peanut shells on the floor or on tables in bar-style venues — dust, not just the food.

What to ask restaurant staff

Specific questions get specific answers. Asking whether a dish is safe usually does not.

  • Does the kitchen keep peanuts or peanut butter on the premises at all?
  • Which oil do you deep-fry in, and is the fryer shared with breaded or coated items?
  • Is this sauce made here, and can someone read the label on any bought-in sauce or paste?
  • Is dessert plated in the same area as nut-based items?

Dishes that often contain peanut

Patterns worth checking, not a list of dishes to rule out.

  • Satay skewers and peanut dipping sauces
  • Mole, some korma and massaman-style curries
  • Pad thai and many stir-fry garnishes
  • Ice-cream toppings, brittle and bakery display items
  • Meat-free dishes built on peanut-based sauces

Dishes that often work

These are starting points to discuss with the kitchen. No dish is safe by category — every one of them depends on that kitchen's ingredients and equipment.

  • Grilled or roasted meat and fish with plain sides — confirm the marinade first
  • Pasta with a tomato-based sauce made in-house
  • Rice and vegetables cooked in a clean pan on request
  • Salads dressed at the table rather than pre-tossed

Common questions

Is peanut oil safe if you have a peanut allergy?

Highly refined peanut oil has almost all protein removed and is tolerated by most people with peanut allergy, but cold-pressed, expelled or 'gourmet' peanut oil is not. Restaurants rarely know which grade they buy, so allergy clinicians generally advise treating any peanut oil as unsafe unless the kitchen can show you the label.

Are peanuts the same as tree nuts?

No. Peanuts are legumes that grow underground; almonds, cashews, walnuts and hazelnuts grow on trees. Many people react to only one group. Kitchens usually store and handle them together, though, so the cross-contact risk is shared even when the allergy is not.

Does 'may contain traces of peanut' mean the food is unsafe?

That is a voluntary cross-contact warning, not a declared ingredient, and EU law sets no threshold behind it — so its meaning varies between producers. People at risk of anaphylaxis are normally advised to avoid products carrying it.

What should I actually say to restaurant staff?

Use the word allergy, not preference. Name the food, say what a reaction does, and ask them to pass it to the kitchen. Under EU Regulation 1169/2011 the business must be able to tell you whether peanut is an ingredient, including in food sold loose.

Advisory, not medical advice

MealSafe is a planning aid, not medical advice. AI-generated assessments can be incomplete or wrong, and ingredients and kitchen routines change without notice. Always confirm with the kitchen, the producer or the label before you eat, and follow the advice of your own clinician.
