Crispy Thick-Cut Steak Fries
Inspired by techniques from America's Test Kitchen, Serious Eats and NYT Cooking.
Thick potato wedges are parboiled until tender, coated in cornflour, then fried twice - first at a lower temperature to cook through, then hotter to crisp - for a fluffy centre and deeply golden crust.

Method
- 1
Parboil the wedges. Cover the potato wedges with cold water in a large pan, add the 20 g salt and bring to a gentle simmer; cook for 6-8 minutes until tender but not falling apart. Since these are thick cuts, cooking them through before frying stops the outside from burning long before the centre is done.
- 2
Dry and coat. Drain the wedges on kitchen paper and leave to cool for 10 minutes, then pat them dry. Toss with the cornflour until lightly and evenly coated; the starch forms a crisp crust on a cut this thick once it hits the hot oil.
- 3
First fry at 160°C. Heat the frying oil to 160°C and fry the wedges in 2-3 batches for 4-5 minutes, until a pale crust just forms. Drain each batch on a wire rack; this gentler first fry sets the crust without colouring it too far, leaving room for the second fry to finish the job.
- 4
Second fry at 190°C. Raise the oil temperature to 190°C and fry the wedges again in batches for 3-4 minutes, until deep golden and crisp all over. The higher heat this time drives off surface moisture fast, giving the deep, crunchy crust steak fries are known for.
- 5
Season and serve. Drain the finished wedges, season with the salt and pepper, and serve immediately while the crust is at its crispest. Never leave hot oil unattended at any stage of frying.

Cat tip
Cut the wedges to an even size - about 8 per potato - so they parboil and fry at the same rate.
More from the cat
- A common mistake is skipping the two-stage fry on thick cuts like these; a single fry either burns the outside or leaves the middle underdone.
- Pat the parboiled wedges completely dry before coating with cornflour, or the starch will clump instead of coating evenly.
- Keep a thermometer in the oil throughout frying - temperature that drifts too low gives soggy, pale fries.
Storage
Best eaten straight away; leftovers keep in the fridge for up to 2 days but lose their crispness. Reheat in a hot oven until piping hot (74°C) rather than the microwave; freezing isn't recommended as the texture suffers on thawing. Cool leftovers in a shallow container and refrigerate within 2 hours (within 1 hour on a day above 32°C).
