Set up safely

Clean the board, pan, and utensils before starting French Onion Potato Soup. Check labels on onions, potatoes, gruyere, plus any sauces, stock, spice blends, and toppings.

This is the step that prevents most accidental gluten exposure.

Gluten-free safety during cooking
  • - Check sauces, stocks, spice mixes, sausages, cornflakes, oats, baking powder, and specialist free-from products every time because labels change.
  • - Use clean boards, pans, colanders, toaster bags, and utensils if the kitchen also handles wheat.
  • - Avoid shared fryers, open bakery bins, and bulk scoop ingredients for coeliac cooking.

  • 300 g onions
  • 220 g potatoes
  • 120 g gruyere

Budget swaps

  • Use own-brand tins, frozen vegetables, and larger gluten-free staple packs where available.
  • Stretch the meal with rice, potatoes, beans, lentils, or salad rather than expensive free-from extras.
  • Batch-cook the core filling and add fresh toppings only when serving.

Substitutions

  • Use a certified gluten-free equivalent for any specialist bread, pasta, wrapper, stock, or sauce.
  • Swap the main protein for beans, tofu, chicken, or tinned fish based on budget and dietary needs.
  • Use dairy-free yogurt, cheese, or cream where needed; re-check labels on every swap.

Serve with

  • Gluten-free toast
  • Side salad
  • Cheese

Storage

  • Cool quickly and refrigerate in a sealed container for up to three days.
  • Freeze in labelled portions for up to three months.
