How do I ask if a dish contains nuts in English?

Use the three-part request rather than a single question: I'm allergic to peanuts. Even a small amount is dangerous for me. Could you check with the kitchen whether this dish or its oil contains peanuts? The last line is the important one, because it asks a member of staff to go and check instead of answering from memory.

Narrow the answer before you accept it. If the kitchen replies with a category word such as nuts or dairy, ask about the specific forms by name - peanut oil, nut butter, a garnish of crushed nuts - because a dish can be free of visible nuts and still be cooked in an oil that carries them. The oil is the question learners forget most often and the one that catches the most cases.
