🥔 Step-by-Step: How to Prepare Roast Potatoes in Advance
1️⃣ Peel and Cut the Potatoes
Use floury varieties for the best crispy finish:
✔ Maris Piper
✔ King Edward
✔ Rooster
Cut into evenly sized chunks so they cook uniformly.
2️⃣ Parboil the Potatoes
Bring salted water to the boil.
👉 Parboil for 8–10 minutes
until the edges are soft but the potatoes still hold their shape.
Drain and let steam evaporate for a couple of minutes.
3️⃣ Rough Up the Edges
Shake the potatoes gently in the pan to create fluffy surfaces that crisp beautifully during roasting.
4️⃣ Coat in Fat
Mix with:
✔ goose or duck fat
✔ vegetable oil
✔ rapeseed oil
✔ beef dripping
Add salt, pepper and optional flavourings (rosemary, thyme, garlic powder).
5️⃣ Choose Your Make-Ahead Method
Three methods depending on how far ahead you’re prepping.
🔹 OPTION A: Prep the Night Before (Fridge Method)
Ideal for next-day roasts.
How to do it:
- Parboil and rough up potatoes
- Coat lightly in oil/fat
- Cool completely
- Place on a tray
- Cover and refrigerate for up to 24 hours
On the day:
Roast at 200–220°C for 40–50 minutes until golden.
🔹 OPTION B: Freeze Parboiled Potatoes (Best for Christmas)
Great for prepping weeks in advance.
How to freeze:
- Parboil, rough up and cool
- Spread on a tray and freeze individually
- Transfer to freezer bags
- Keep for up to 3 months
How to cook from frozen:
Roast in hot fat at 220°C for 45–55 minutes
(no need to defrost).
🔹 OPTION C: Pre-Roast and Reheat
Perfect when oven space is tight on the day.
Pre-roast:
- Parboil
- Roast for 20–25 minutes until pale golden
- Cool fully
- Refrigerate for 24 hours or freeze for 3 months
Reheat:
- From fridge: 20–25 minutes
- From freezer: 30–35 minutes
🥔 Extra Tips for the Crispiest Roast Potatoes
✔ Preheat the tray and fat
The potatoes must sizzle when they hit the tin.
✔ Don’t overcrowd
Space helps them crisp.
✔ Turn halfway
Even golden colour.
✔ Use very hot fat
Goose fat gives unbeatable crispiness.
✔ Dry potatoes properly
Wet potatoes = soggy roasties.
❌ Common Mistakes to Avoid
❌ Under-parboiling
Potatoes won’t fluff up.
❌ Adding garlic too early
It burns — add during the last 15 minutes.
❌ Using waxy potatoes
They won’t crisp properly.
❌ Cooling potatoes in a covered bowl
They steam and go soft.
❌ Storing when still warm
Causes condensation and mushiness.
