Mexican food with a peanut allergy

Peanut appears in Mexican cooking mainly through mole, encacahuatado and some salsas, where it is ground into the sauce rather than visible — so the question is what thickens the sauce, and the rest of the menu is usually straightforward.

How Mexican kitchens work

Mexican cooking is maize-based at its core, which helps gluten-free eating, but restaurant versions lean heavily on cheese and crema, and mole and some sauces carry nuts, seeds and chocolate.

Mexican dishes that often contain peanut

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

  • Mole and encacahuatado sauces thickened with peanut
  • Some salsa macha and chilli oils made with peanuts
  • Desserts, brittle and snack mixes
  • Fusion dishes using peanut-based dressings

Dishes that often work

Starting points for a conversation with the kitchen. No dish is safe by category — it depends on that kitchen's ingredients and equipment.

  • Tacos, tostadas and grilled meat with fresh salsa
  • Beans, rice and vegetable dishes
  • Guacamole and pico de gallo
  • Ceviche and grilled fish

What to ask

Questions that produce a usable answer rather than a reassurance.

  • Is the sauce thickened with peanut or other nuts?
  • Does the chilli oil or salsa macha contain peanuts?
  • Is the same blender used for peanut-based sauces?

Common questions

Which Mexican dishes contain peanut?

Mole variants and encacahuatado are the main ones, and salsa macha is often peanut-based. Peanut is ground into the sauce, so it is never visible — ask about the thickener.

Is salsa macha a risk?

Frequently. It is a chilli oil that commonly includes peanuts, sesame or both, and it is often placed on the table as a condiment rather than being described as part of the dish.

Is peanut oil used in Mexican kitchens?

Less often than in some other cuisines — vegetable and corn oil are more common — but the oil in a restaurant fryer is generally an unlabelled blend, so it is still worth asking which.
