I’m cooking gluten-free for a coeliac guest: how do I keep it safe?
Cooking for a coeliac guest is one of the kindest things a host can do, and with a little preparation it is entirely manageable. The whole job is preventing cross-contact at every stage, and being honest about anything you are unsure of.
Short answer
Prevent cross-contact, and check every label. Wipe surfaces, wash hands and use clean utensils before you start; prepare the gluten-free element first; keep it covered if gluten cooking is happening alongside; and read the label on every sauce, stock cube and condiment rather than assuming. Above all, tell your guest honestly if you are not certain about a dish.
Before you start
- Wipe down all work surfaces.
- Wash your hands thoroughly before handling gluten-free ingredients.
- Use clean utensils, not ones that have been sitting in a pot of pasta.
- Check your ingredients carefully. “This sauce has been in my cupboard for years” is not a reliable indicator: read the label, every time.
During preparation
- Prepare the gluten-free element first, before other cooking happens, if you can.
- Do not reuse the same tongs, spoons or boards that have touched bread or pasta without washing them in between.
- Keep the gluten-free dish covered if gluten-containing cooking is happening at the same time.
Common slip-ups and the swaps that fix them
| Hidden gluten trap | Gluten-free swap |
|---|---|
| Plain flour to dust a surface for pastry | Gluten-free flour, or roll on parchment |
| Plain flour to thicken a sauce | Cornflour, potato starch or a certified GF blend |
| Shared bread knife near GF food | A clean, dedicated knife kept away from GF dishes |
| Regular soy sauce | Tamari labelled gluten-free |
| Stock cubes, gravy, ready-made sauces | A version labelled gluten-free (check every time) |
The most important thing
Ask your guest directly what they are confident eating, and be honest if you are not sure about something. A coeliac guest who knows a dish is uncertain can make an informed choice. A coeliac guest who is told everything is fine when it is not gets ill. Honesty is the single most protective thing on the table, and if you want to understand why even a trace matters, see is a little gluten OK for a coeliac?
The bottom line
The recipe is the easy part: the care is in the details. Clean surfaces and utensils, prepare the gluten-free food first, read every label, and be honest about anything you are not sure of. A guest who is told the truth can always make an informed choice.
