Confit potatoes

Just when you thought potatoes had been cooked in every way possible, along comes this legendary side dish from The Quality Chop House. Thinly sliced potatoes are confit in duck fat before being pressed overnight and deep-fried until crisp. The shattering crunch and almost creamy centre make these better than any chips or roast potatoes you've had before.

Our confit potatoes have become rather legendary. They are the only dish we haven’t once taken off the menu since their happy conception in spring 2013. We’d just opened the restaurant and needed to find something to serve with the chops. Shaun was adamant that QCH didn’t need chips – next thing you know we’d have squeezy ketchup on the tables – but we obviously needed something indulgent, and probably potato-based. We started making layered potatoes and after much trial and error and refrying leftovers, Shaun landed on these crispy golden nuggets.

What with the slicing, layering and overnight chilling, these are something of a labour of love – but they’re worth it. Do use Maris Pipers: they have the perfect sugar-starch-water content to prevent collapse while cooking.




Mustard dressing


  • Terrine mould
  • Mandoline


Preheat an oven to 120°C/gas mark ½ and line a 1.7l terrine mould with baking paper
Use a mandoline to slice the potatoes as thinly as possible, then toss the slices with the duck fat and tablespoon of salt in a large bowl
Layer the potatoes in the mould, one slice at a time, until you’ve built up multiple tiers. Once you’ve used up all the potatoes, cover the top with baking parchment and cook for about 3 hours until the potatoes are completely tender
Place a small baking tray or plate on top of the baking paper covering the potatoes, along with a few heavy weights (tins work well) and leave to cool, then refrigerate overnight to compress
The next day, remove the weights and tray and cut the potatoes into 3x3cm pieces
To make the mustard dressing, mix the mustard, lemon juice and vinegar in a large bowl, then whisk in the vegetable oil until emulsified. Store in squeezy bottles in the fridge until you’re ready to serve. This will make more dressing than you need for these potatoes, but it will keep for a few days and can be served with all sorts of other dishes
Preheat a deep pan of oil or deep-fat fryer to 190°C
Fry the sliced pieces of potato in the oil for around 4 minutes until croissant-gold (you may need to work in batches). Sprinkle over some Maldon salt, drizzle with the mustard dressing and eat immediately
