Gluten-free breadcrumbs and coatings with vegan binders
Crumb coatings turn vegetables, tofu, mushrooms and patties into something crisp. Ordinary breadcrumbs are made from wheat bread, so they are one of the first things to replace on a gluten-free diet, and the usual egg wash is the next if you are also vegan. The good news is that both swaps are easy. Gluten-free crumbs can come from gluten-free bread, from crushed cereal or from ground nuts and seeds, and the egg step can be replaced with a thick plant-milk or starch batter. This guide covers each kind of crumb, how to make it, what to watch for on the label, and the dredge, binder and crumb sequence that gives a coating that stays on.
Choosing a crumb
| Crumb | How to make it | Texture | Points to watch |
|---|---|---|---|
| Gluten-free bread crumbs | Dry slices in a low oven or leave them out to go stale, then blitz or grate | Closest to ordinary crumbs. Fine or coarse depending on how you grind. | Check that the loaf is labelled gluten-free and vegan if needed. Many loaves contain egg or milk. |
| Panko-style gluten-free crumbs | Bought, usually made from rice or corn | Light, airy and very crisp | Many panko products are made from wheat. Look for a gluten-free label. |
| Crushed cornflakes | Crush in a bag or blitz briefly | Crunchy, golden and a little sweet | Many cornflakes contain barley malt flavouring. Check the label for malt, barley and wheat. |
| Rice crumbs | Crush plain puffed rice cereal, or use rice cracker crumbs | Light and crisp | Check the label, as with cereal. Some rice cereals contain barley malt. |
| Cornmeal or polenta | Use as is, or mix with a little flour | Gritty and sturdy, good for frying | Good for fish-style tofu, okra and green tomatoes. |
| Ground nuts and seeds | Pulse almonds, sesame, sunflower or pumpkin seeds in a food processor | Rich and nutty, browns faster | Not suitable for people with nut or seed allergies. Pulse briefly, since overprocessing makes a paste. |
| Crushed crackers or crisps | Bag and crush, then sieve out large pieces | Salty and crisp | Check the label for wheat and for gluten-containing flavourings. |
Whichever you choose, season the crumb as well as the filling. A pinch of salt, pepper, smoked paprika, garlic powder, dried herbs or nutritional yeast does a lot. Check the labels of any spice blends you add.
Making crumbs from bread
Gluten-free bread dries out and crumbles faster than wheat bread, which suits crumb making. Cut slices, spread them on a baking tray and dry them in a low oven until crisp throughout, or leave them out for a day or two. When completely dry, break them up and blitz in a food processor, or put them in a bag and crush with a rolling pin. Sieve if you want a uniform crumb.
Keep the crumbs in an airtight container. Crumbs that are fully dry keep well in the freezer, and a store of leftover heels and end slices can be turned into crumbs in this way, so little bread is wasted. If the crumbs smell stale or show any mould, throw them away.
The dredge, binder and crumb sequence
The standard coating has three stages, set out in three shallow dishes: flour, binder and crumbs. Each layer sticks to the one below it. The flour dries the surface and gives the binder something to grip. The binder acts as the glue. The crumb gives the crunch.
- Pat the food dry. Wet surfaces make the coating slide off.
- Dredge: roll it in a dish of seasoned flour. A gluten-free plain blend, rice flour, cornflour (cornstarch), potato starch or chickpea flour all work. Shake off any extra.
- Binder: dip it in the wet mixture, as described below, and let the extra drip back.
- Crumb: press it into the crumbs with a dry hand, so the crumbs stick all over.
- Rest the coated pieces on a rack or tray for a short while, if you have time, to let the coating set.
- Cook, by shallow frying, baking on a hot oiled tray, or air frying.
Keep one hand for wet and one for dry when you work, or the crumb builds up into lumps on your fingers. Use clean, separate dishes and tongs or a fork for each stage.
Vegan binders
An egg wash is just a wet, slightly sticky liquid that gives crumbs something to grip. Several plant alternatives do the same job.
| Binder | How to use it | Notes |
|---|---|---|
| Plant milk with a starch or flour | Whisk plain plant milk with a spoonful or two of cornflour or gluten-free flour until it is like thin cream | Easy and cheap. Use unsweetened plant milk. |
| Plain plant yoghurt | Thin with a splash of plant milk | Thick and sticks well. Good for baked coatings. |
| Aquafaba | Whisk the liquid from a tin of chickpeas until a little frothy | Closest to egg white. See our aquafaba guide. |
| Flax or chia gel | Stir ground flax or chia into water and leave to thicken | Sticky and strong. Can leave flecks. See our flax and chia guide. |
| Mustard and plant milk | Whisk a little mustard into plant milk | Adds flavour. Check the mustard label. |
| Mayonnaise (vegan) | Brush on thinly | Works for baked coatings. Check the label for gluten. |
A binder needs to be thick enough to cling and thin enough to coat evenly. If it runs straight off a spoon like water, add a little more flour or starch. If it forms clumps, thin it with a splash of plant milk.
Cooking the coating and fixing problems
- Coating falls off: the food was wet, the flour layer was skipped, or the pieces were moved too much in the pan. Pat dry, dredge well and turn once.
- Crumbs go soggy: not enough heat, or the tray was overcrowded. For baking, preheat the tray and use a rack so air circulates. Spray or brush the crumbs lightly with oil to help colour.
- Crumbs burn before the inside is cooked: heat too high, or nut crumbs, which brown quickly. Lower the heat, cut the food thinner, or bake to finish.
- Greasy result when frying: oil not hot enough. Do not crowd the pan, and drain on a rack rather than paper.
- Gluten-free crumbs seem fragile: they are, and they absorb oil. Press them on firmly and handle the coated food gently.
Foods that coat well include thick slices of aubergine, courgette, cauliflower florets, mushrooms, pressed tofu or tempeh, and bean or lentil patties. Dense mixtures need a binder inside, as described in our guide to egg-free binders for burgers and patties.
Labels and cross-contact
The crumb, the flour and the binder each need a gluten check. Cereal, crackers, spice mixes, stock powders and some starches may contain wheat or barley malt. Frying in oil that has cooked wheat-coated food passes gluten to your food, and so can a shared baking tray or sieve. For coeliac disease, follow the advice of a coeliac society or clinician, and read labels each time.
What this guide is based on
- That a coating works as flour, then a sticky binder, then crumbs, that dry bread makes crumbs, and that ground nuts brown faster than bread crumbs, is general cooking knowledge.
- That ordinary breadcrumbs and most panko are made from wheat, and that some breakfast cereals use barley malt flavouring, is general label knowledge. Products differ by brand and change over time, so check each label.
- No exact amounts, oven temperatures or cooking times are given, because they depend on the food and equipment. This guide is not based on our own test cooking.
- Allergy and coeliac statements are general. Read labels and ask a coeliac society, doctor or dietitian about your own needs.
