A club sandwich is three slices of toast and two fillings: chicken with mayonnaise on one layer, bacon with lettuce and tomato on the other. The middle slice is not showing off. It is structural, and it is the reason the sandwich can hold wet and dry ingredients at once without turning to pulp.
Get the order of the layers right and it holds together to the last bite. Get it wrong and you are eating it with a fork off the plate.
What actually goes in one
| Component | Amount, per sandwich | Notes |
|---|---|---|
| White bread | 3 slices, medium cut | About 14 to 16 mm. Thick cut makes it too tall to eat. |
| Cooked chicken breast | 80 to 100 g, sliced | Roast or poached. Turkey is the older version. |
| Streaky bacon | 3 rashers, cooked crisp | Crisp, not floppy. Floppy bacon makes it impossible to bite through. |
| Mayonnaise | 2 tbsp | Full fat. It is doing structural work as well as flavour. |
| Tomato | 2 slices | Salted and drained. This is not optional. |
| Lettuce | 2 leaves | Little gem or iceberg. It has to be crisp and dry. |
| Butter | A thin layer | On the dry faces, as a moisture barrier. |
Chicken or turkey is the one genuine argument. The sandwich is older than the chicken version, and turkey is what most American diners still use. Chicken is what nearly every British kitchen serves. Either is correct; turkey is drier and needs more mayonnaise.
Why three slices
Because the two fillings have incompatible moisture. Tomato and lettuce leak water. Chicken and mayonnaise are rich and soft. Put them all between two slices and you get one thick, sliding mass, and the water from the tomato runs straight into the bread under the chicken.
The middle slice separates them. It absorbs a little moisture from above, blocks the rest, and gives the stack something rigid in the centre so it can be cut into quarters and stay standing. That is the whole design.
It also makes the sandwich about 6 cm tall, which is why it comes cut into triangles with cocktail sticks through them. The sticks are not decoration either; they are what stops the top two layers sliding off as you pick it up.
The build, in order
Order matters more here than in any other sandwich on this blog.
- Toast all three slices to a medium shade. Not dark. They need to be firm enough to hold the load but still soft enough to bite cleanly through three layers at once.
- Butter the slices while hot, on the faces that will touch wet ingredients. Butter is a water barrier, and it is why the base slice survives.
- Slice one, bottom. Mayonnaise, then the chicken, then a little more mayonnaise. The mayonnaise goes above and below the chicken so it does not slide.
- Slice two, the middle. Butter both faces of this one. It is taking moisture from both directions.
- On top of the middle slice: lettuce first, then tomato, then bacon. Lettuce against the bread is a second barrier under the tomato, and the bacon sits on top where it stays crisp.
- Slice three, the lid. Buttered side down.
- Press gently, skewer, then cut. Four cocktail sticks, one in each quarter, pushed in before the knife goes anywhere near it.
- Cut corner to corner into four triangles with a serrated knife, using a sawing motion and no downward pressure.
The timing problem, and how a four-slice toaster solves it
Three slices of toast have to arrive at the same moment, and they have to be buttered while hot. On a two-slice toaster you toast two, they sit and go cold and leathery while the third runs, and by the time you build the sandwich the first two have steamed themselves soft on the plate.
It is a small thing that makes a real difference, and it is why a club sandwich is the dish that most obviously rewards four slots. The 4 Slice Smart Toaster runs all three at once on one setting, and a countdown display tells you exactly how long you have to get the bacon out of the pan, which we wrote about in why a countdown timer matters.
If you are making two club sandwiches, that is six slices, and the difference stops being small. For one or two people the 2 Slice Smart Toaster is usually the right buy; this is one of the few everyday dishes that argues otherwise. Both are in the Toastley toaster range.
The tomato rule
Slice the tomato, lay the slices on kitchen paper, salt them lightly, and leave them for ten minutes. Then pat them dry.
A tomato is about 94 per cent water and a good deal of that is loose. Salting draws it out and concentrates the flavour at the same time, so you get a better-tasting tomato and a sandwich that is still intact five minutes later. Skipping this is the single most common reason a club sandwich goes soggy, and no amount of butter compensates for it.
The same technique applies anywhere tomato meets toast, including bruschetta and pizza toast.
Getting the bacon right
- Streaky, not back. Streaky crisps evenly and breaks cleanly when you bite. Back bacon stays chewy and pulls the whole filling out in one piece.
- Start it in a cold pan over a medium heat. The fat renders gradually instead of seizing, and you get flat, crisp rashers rather than curled ones.
- Drain on kitchen paper. Bacon fat soaks into toast faster than anything else here.
- Break the rashers to fit the slice. Overhanging bacon is what drags a layer out when you bite.
Variations that are still a club
- Turkey club. The original. More mayonnaise, because turkey is drier.
- Egg mayonnaise club. Replaces the chicken layer. Very good, and cheaper.
- Vegetarian club. Halloumi or a thick slice of grilled aubergine in place of the chicken, smoked paprika mayonnaise in place of the bacon.
- Avocado club. Mashed and seasoned in a bowl before it goes near the bread, for the reasons set out in avocado on toast.
- Cheese club. Add a slice of cheddar to the chicken layer while the toast is hot so it softens.
What stops being a club: two slices instead of three, or untoasted bread. At that point it is a very good sandwich with a different name.
Where it came from
The usual account places it in an American gentlemen's club in the 1890s, most often the Union Club of New York, though the story is contested and at least three establishments have claimed it. The earliest printed recipes describe two slices of toast with turkey, bacon and lettuce; the third slice and the chicken came later.
So the three-slice version people argue about being definitive is, on the evidence, the newer one. It is also the better one, for the structural reasons above.
Common questions
What is in a club sandwich?
Three slices of toast with two fillings: chicken or turkey with mayonnaise on the lower layer, and bacon, lettuce and tomato on the upper layer. It is cut into four triangles and held with cocktail sticks.
Why does a club sandwich have three slices of bread?
The middle slice separates two fillings with different moisture levels. It blocks water from the tomato reaching the chicken layer and gives the stack rigidity so it can be cut into quarters and stay standing.
Is a club sandwich chicken or turkey?
Both are correct. Turkey is the older version and still standard in American diners; chicken is what most British kitchens use. Turkey is drier, so it needs more mayonnaise.
How do you stop a club sandwich going soggy?
Salt the tomato slices and drain them on kitchen paper for ten minutes, butter the toast while it is hot as a moisture barrier, and put the lettuce directly under the tomato as a second barrier.
Should the bread be toasted for a club sandwich?
Yes, to a medium shade. It has to be firm enough to carry the load but still soft enough to bite cleanly through three layers. Dark toast shatters when you bite it.
What order do the layers go in?
Bottom slice, mayonnaise, chicken, mayonnaise, middle slice buttered both sides, lettuce, tomato, bacon, top slice. Skewer with cocktail sticks before cutting into four triangles.
