The short version
Soften sliced leeks in butter for 8–10 minutes until sweet and dry, cool them, then top a 72% hydration focaccia with the leeks and grated mature cheddar and bake at 230°C/450°F for 20–24 minutes until the cheese is molten and deep gold.
Why this works
Sweating the leeks first collapses them and releases their water, so they add sweetness rather than steam; mature cheddar has enough fat and flavor to melt and brown without turning rubbery; a standard 72% focaccia stays tall under the topping.

Ingredients
Method
- 1
Soften the leeks (make ahead)
Melt the butter over medium-low heat, add the sliced leeks, the 1/4 tsp salt and thyme, and cook gently 8–10 minutes until soft, sweet and collapsed. Cool completely.
Look for: Leeks turn silky and translucent with no raw squeak; no liquid pools in the pan.
Avoid: Do not brown them hard or leave them raw — raw leeks stay watery and squeaky on the bread. Cool fully before topping.
- 2
Mix the dough
Whisk flour and yeast, add water and 15 g of the oil, then the 9 g salt. Mix to a shaggy, sticky dough.
Look for: Wet and tacky but cohesive.
- 3
Bulk ferment with folds
Do 2–3 stretch-and-folds over 90 minutes, then rest until nearly doubled.
Look for: Domed, jiggly and bubbly.
- 4
Pan and proof
Oil the pan with the remaining oil, add the dough, stretch toward the edges, and proof until puffy, about 1 hour.
Look for: Dough relaxes into the pan and jiggles when nudged.
- 5
Dimple, top and bake
Dimple all over with oiled fingers. Spread the cooled leeks evenly, scatter the grated cheddar, grind over pepper, and bake at 230°C/450°F for 20–24 minutes.
Look for: Cheddar is molten and freckled brown; edges deep gold and base crisp.
- 6
Finish and cool
Sprinkle a light pinch of flaky salt and cool on a rack 10–15 minutes before slicing.
Look for: The cheesy top sets slightly so slices cut cleanly.
What good looks like
- Crumb: Open and airy, enriched where the leeks sit.
- Crust: Crisp base; tender edges.
- Height: About 3 cm tall.
- Color: Deep gold with molten, freckled cheddar.
If something went wrong
| Symptom | Likely cause | Fix |
|---|---|---|
| Watery, squeaky leeks | Leeks added raw or under-softened | Sweat them until fully soft and dry, then cool before topping. |
| Cheese greasy or rubbery | Over-baked or too hot | Hold 230°C/450°F and pull once the cheddar is just molten and browning. |
| Too salty | Full dough salt plus salty cheddar | Keep dough salt at 9 g and finish with only a light pinch. |
Storing & reheating

Freezing: Freeze cooled pieces up to 1 month, wrapped well.
Reheating: Warm in a 200°C/400°F oven 5–7 minutes to re-melt the cheese.

Frequently asked
- Can I cook the leeks ahead?
- Yes — sweat them a day ahead, refrigerate, and bring to cool room temperature before topping.
- Can I make it vegetarian without butter?
- Yes — soften the leeks in olive oil instead of butter; use a vegetarian-rennet cheddar to keep the whole bread vegetarian.
