🥔🧠 1. What Makes an Oil Good for Roast Potatoes?
The best oils for roasting have:
✔ a high smoke point
✔ neutral or complementary flavour
✔ ability to coat potatoes evenly
Low smoke point oils burn and cause bitterness.
🧈🔥 2. Beef Dripping – The Traditional Favourite
✔ rich, savoury flavour
✔ excellent crisping power
✔ high smoke point
Beef dripping produces classic roast dinner potatoes with deep flavour.
🦆🥔 3. Goose Fat – Rich and Luxurious
✔ lighter than beef dripping
✔ exceptional crispness
✔ slightly sweeter flavour
Popular for festive and special occasion roasts.
🌻🔥 4. Sunflower Oil – A Reliable All-Rounder
✔ high smoke point
✔ neutral flavour
✔ widely available
Ideal for everyday roast potatoes.
🫒🥔 5. Olive Oil – Is It a Good Choice?
✔ adds Mediterranean flavour
✔ best for lower roasting temperatures
✔ extra virgin can burn at high heat
Light olive oil works better than extra virgin for roasting.
🥥🔥 6. Vegetable Oil – Budget-Friendly Option
✔ affordable and accessible
✔ neutral taste
✔ decent crisping results
A practical choice for large batches.
🧈🥔 7. Butter – When and When Not to Use It
❌ low smoke point
✔ excellent flavour
Butter is best mixed with oil or added near the end of cooking.
🌱🔥 8. Rapeseed (Canola) Oil – A Strong Contender
✔ high smoke point
✔ light flavour
✔ widely grown in the UK
A great alternative to sunflower oil.
🥔📏 9. How Much Oil Should You Use?
✔ about 1 tablespoon per person
✔ enough to coat the tray base
✔ potatoes should sizzle, not swim
Too much oil makes potatoes greasy.
🔥🥔 10. Preheating Oil for Maximum Crispiness
✔ always preheat oil in the tray
✔ add potatoes to hot fat
✔ listen for a sizzle
Cold oil leads to soggy results.
⚠️❌ 11. Common Mistakes to Avoid
❌ overcrowding the tray
❌ using low smoke point oils
❌ adding oil after potatoes
❌ roasting at low temperatures
Technique matters as much as oil choice.
