Subway Bread: What It Actually Costs to Make at Home
Subway’s footlong roll has a strange claim to fame: in 2020, Ireland’s Supreme Court ruled that its bread contains too much sugar to legally count as “bread” under Irish tax law — the sugar content is closer to a dessert than a staple loaf. That’s about 10% sugar by weight of flour, which is roughly five times what a traditional bread recipe uses.
Whatever you think of the ruling, that sweetness, plus a soft, slightly chewy crumb, is exactly what makes the roll recognizable. I priced out a homemade version that gets close to the real thing, and it costs a fraction of what six-inch or footlong subs run at the counter.
The cost breakdown
| Ingredient | Amount | Cost |
|---|---|---|
| Bread flour | 3 cups | $0.71 |
| Sugar | 3 tbsp | $0.06 |
| Instant yeast | 2 tsp | $0.22 |
| Salt | 1.5 tsp | $0.02 |
| Warm water | 1 cup | — |
| Olive oil | 2 tbsp | $0.24 |
| Cornmeal (for dusting) | 1 tbsp | $0.03 |
| Total (makes 4 footlong rolls) | $1.28 |
That’s 32 cents a roll, against $4–6 for a footlong sub roll alone at most sandwich chains — before any fillings.
Why the dough behaves differently
Standard bread dough runs about 1–2% sugar relative to the flour weight, mostly to feed the yeast. This recipe runs closer to 8–9%, well past what the yeast needs. The extra sugar caramelizes during baking, which is what gives the crust its light golden-brown color and slightly sweet edge — and it’s also what tipped the scale in that Irish court case. The oil in the dough is doing separate work: it keeps the crumb soft and stretchy instead of crusty, closer to a sandwich roll than a rustic loaf
Subway Bread
Makes 4 footlong rolls · 2.5 hours (mostly rising)
Ingredients
- 3 cups bread flour
- 3 tbsp sugar
- 2 tsp instant yeast
- 1.5 tsp salt
- 1 cup warm water (about 110°F)
- 2 tbsp olive oil
- 1 tbsp cornmeal, for the pan
Instructions
- In a large bowl, whisk together the flour, sugar, yeast, and salt.
- Add the warm water and olive oil. Mix until a shaggy dough forms, then knead on a floured surface for 8–10 minutes, until smooth and elastic.
- Place the dough in a lightly oiled bowl, cover, and let rise in a warm spot for 1 hour, until doubled.
- Punch down the dough and divide into 4 equal pieces. Roll each into a 10–12 inch log.
- Dust a baking sheet with cornmeal and place the logs on it, spaced apart. Cover loosely and let rise 30–40 minutes, until puffy.
- Preheat the oven to 375°F. Slash each roll lengthwise down the center, about ¼ inch deep.
- Bake 18–20 minutes, until golden brown and hollow-sounding when tapped. Cool at least 10 minutes before slicing.
