Ingredients
For the Jacket Potatoes
- 4 large baking potatoes (such as Maris Piper or King Edward)
- 1–2 tbsp olive oil
- 1 tsp sea salt
Optional Toppings
- Butter
- Grated cheddar cheese
- Baked beans
- Sour cream
- Fresh chives, chopped
How to Make Delia Smith Jacket Potatoes
- Prepare the oven: Preheat the oven to 200°C or 180°C fan. Place a shelf in the centre of the oven for even cooking.
- Prepare the potatoes: Wash and scrub the potatoes thoroughly, then pat them completely dry with a clean towel.
- Prick and oil: Pierce each potato several times with a fork. Rub all over with olive oil and sprinkle generously with sea salt.
- Bake the potatoes: Place directly on the oven shelf or on a baking tray. Bake for 1 hour 15 minutes to 1 hour 30 minutes until the skins are crisp and the centres are soft when squeezed.
- Check doneness: Insert a knife or skewer into the centre. It should slide in easily without resistance.
- Serve and assemble: Cut a cross in the top of each potato, gently squeeze to open, fluff the interior with a fork, and add butter and your chosen toppings.

Tips
How do I get really crispy skins?
Make sure the potatoes are completely dry before oiling, and bake them directly on the oven shelf rather than wrapping in foil.
Why are my potatoes not fluffy inside?
They may need more baking time. Larger potatoes require longer to soften fully in the centre.
Should I wrap jacket potatoes in foil?
No, foil traps steam and prevents the skins from becoming crisp. Bake them uncovered for best results.
Which potatoes are best for baking?
Floury varieties like Maris Piper or King Edward give the fluffiest interior and crisp skin.
Serving Suggestions
- Serve with butter and grated cheddar for a classic option
- Top with baked beans for a hearty meal
- Add sour cream and chives for a lighter finish
- Pair with a fresh green salad on the side
