  • butter, for frying

Instructions

  1. 1

    Melt butter in a medium nonstick frying pan and cook the sliced leek until softened, about 5 minutes.

  2. 2

    While leek cooks, cut potatoes in half and slice to about ¼" thick.

  3. 3

    Beat eggs, season, then stir in cheese and sage.

  4. 4

    Add extra butter to pan if needed, tip in potatoes, then pour in egg mixture.

  5. 5

    Turn heat to low and cook until nearly set, about 10 minutes.

  6. 6

    Transfer pan under a hot grill and cook a couple of minutes more until top is set and golden.

  7. 7

    Slice into wedges and serve with green salad.

Tips

Tip 1

Use waxy potatoes that hold shape when cooked and cooled, not floury varieties.

Tip 2

Ensure potatoes are fully cooled before slicing to prevent breaking apart in the pan.

Tip 3

Keep heat low during stovetop cooking to prevent eggs setting too fast on bottom while center remains wet.

Tip 4

Watch closely under grill as cooking time varies by broiler intensity.

Good to Know

Storage

Cover and refrigerate up to 3 days. Reheat gently in oven to 160C until warm through.

Make Ahead

Potatoes can be cooked and cooled up to 1 day ahead. Prepare tortilla up to 4 hours before serving and store chilled; serve at room temperature or reheat gently.

Serve With

Serve warm or at room temperature with a crisp green salad and crusty bread.

Common Mistakes

Watch

Use floury potatoes instead of waxy ones to avoid mushy, falling-apart texture.

Watch

Add cold potatoes directly to hot pan to avoid them breaking apart.

Watch

Use high heat throughout cooking to avoid custard-like, undercooked center.

Watch

Neglect to watch under grill to avoid burnt or unevenly set top.
