🥔 Step-by-Step: How to Make the Crispiest Christmas Roast Potatoes
1️⃣ Choose the Right Potatoes
For Christmas crunch, choose floury potatoes:
✔ Maris Piper
✔ King Edward
✔ Rooster
Avoid waxy varieties — they won’t crisp.
2️⃣ Peel & Cut into Even Chunks
Keep sizes consistent so they cook evenly.
Medium-large chunks work best for fluffy centres.
3️⃣ Parboil the Potatoes Properly
Bring salted water to a boil and add potatoes.
👉 Parboil for 8–10 minutes
until the edges soften but the centres remain firm.
Drain and leave to steam dry — moisture kills crispiness.
4️⃣ Rough Up the Edges
Shake potatoes in the pan to create a fluffy surface.
This step is essential — the fluffy bits go crispy in the oven.
5️⃣ Heat Your Fat Until Smoking Hot
Use one of these for the crispiest finish:
✔ Goose fat (classic Christmas choice)
✔ Beef dripping
✔ Rapeseed oil (if vegetarian)
✔ Vegetable oil
Place the fat in your roasting tin and heat in the oven at 220°C until sizzling.
6️⃣ Coat the Potatoes Thoroughly
Tip the potatoes straight into the hot fat — they should sizzle immediately.
Turn carefully until fully coated.
7️⃣ Season Generously
Add:
✔ sea salt
✔ black pepper
✔ rosemary
✔ thyme
✔ optional garlic (add near the end to avoid burning)
8️⃣ Roast at a High Temperature
Roast at 200–220°C for 45–55 minutes, turning halfway.
They should be:
✔ golden
✔ blistered
✔ crunchy on the outside
✔ fluffy inside
🎄 Extra Tips for Christmas-Day Perfection
✔ Preheat the roasting tin
The fat must be smoking hot.
✔ Don’t overcrowd the tray
Potatoes need space to crisp.
✔ Use a metal tin, not ceramic
Metal conducts heat better.
✔ Add garlic in the last 15 minutes
Prevents burning and bitterness.
✔ Finish with flaky sea salt
Adds crunch and flavour.
❌ Common Christmas Roast Potato Mistakes
❌ Starting with cold fat
Results in pale, soggy potatoes.
❌ Using the wrong potatoes
Waxy potatoes don’t crisp well.
❌ Parboiling too little or too long
Edges must be softened, not mushy.
❌ Adding wet potatoes to hot fat
Causes splashing and ruins crispiness.
❌ Overcrowding the oven
Your oven must stay hot for crunch.
