Ingredients
For the potatoes
- 1.5kg Maris Piper or King Edward potatoes, peeled and cut into chunks
- 2 tablespoons fine semolina
- 4 tablespoons vegetable oil or goose fat
- 1 teaspoon salt
- ½ teaspoon black pepper
Optional flavourings
- 2 cloves garlic, lightly crushed
- 1–2 sprigs fresh rosemary
How to Make Mary Berry Roast Potatoes with Semolina Recipe
- Prepare the oven: Preheat the oven to 220°C or 200°C fan. Place a large roasting tray inside the oven to heat up so the potatoes start crisping immediately.
- Boil the potatoes: Place the peeled and chopped potatoes into a large saucepan of salted water. Bring to the boil and simmer for 8–10 minutes until the edges are slightly softened.
- Drain and roughen: Drain the potatoes thoroughly in a colander, then gently shake them to rough up the edges. This helps create that signature crispy texture.
- Coat with semolina: Sprinkle the semolina over the potatoes and toss gently until evenly coated.
- Prepare the fat: Carefully remove the hot roasting tray from the oven and add the oil or goose fat. Return it to the oven for a couple of minutes until very hot.
- Roast the potatoes: Carefully add the potatoes to the hot tray, turning them to coat in the fat. Roast for 45–55 minutes, turning halfway through, until golden and crisp.
- Add flavourings: If using garlic and rosemary, add them for the final 15 minutes of cooking.
- Season and serve: Sprinkle with salt and pepper, then serve immediately while hot and crispy.

Tips
Why are my roast potatoes not crispy?
Make sure the oil is very hot before adding the potatoes. Also, roughing up the edges after boiling is key to creating a crisp exterior.
Can I prepare the potatoes in advance?
Yes, you can parboil and rough them up earlier in the day. Leave them uncovered in the fridge, then roast when ready.
What type of potatoes work best?
Floury varieties like Maris Piper or King Edward give the fluffiest interiors and crispiest edges.
Is semolina necessary?
It adds extra crunch, but you can skip it if needed. Flour can be used as a light alternative coating.
Serving Suggestions
- Serve alongside roast chicken, beef, or lamb
- Pair with rich gravy for extra flavour
- Add to a Sunday roast platter with vegetables
- Enjoy with a simple garlic aioli dip

FAQs
Do I have to parboil the potatoes first?

How do I keep roast potatoes warm before serving?
Keep them in a low oven at around 120°C for up to 30 minutes, but avoid covering them to maintain crispness.
Can I add other seasonings?
Absolutely, you can add paprika, garlic powder, or herbs for extra flavour.
