The Mary Berry Potato Rosti Recipe is a wonderfully simple dish with crisp, golden edges and a soft, fluffy centre. It’s the sort of comforting potato recipe that works beautifully for breakfast, brunch or as a hearty side dish alongside meats and salads.
A good potato rosti should be deeply golden and crunchy on the outside while staying tender and light inside. Properly squeezing the grated potatoes is the key to achieving that crisp texture, allowing the natural flavour of the potatoes to shine through without becoming greasy or soggy.
Ingredients
For the Potato Rosti
- 500g potatoes, peeled
- 1 tbsp grated onion
- 2 tbsp plain flour
- 1 tsp salt
- 1/2 tsp black pepper
- 2 tbsp vegetable oil
- 1 tbsp butter
How to Make Mary Berry Potato Rosti Recipe
Prepare the Potatoes
Peel and grate the potatoes, then place them in a clean tea towel and squeeze out as much moisture as possible.
Mix the Ingredients
Combine the grated potatoes with the grated onion, flour, salt and black pepper in a large bowl.
Shape the Rosti
Press the potato mixture into one large round rosti in the frying pan, about 2cm thick, smoothing the top gently with a spatula. Cook it as one large cake rather than individual patties for a crisp golden crust and soft centre.
Heat the Pan
Heat the vegetable oil and butter in a large frying pan over medium heat until hot.
Cook the Rosti
Cook the large rosti over medium heat for 8–10 minutes until deeply golden underneath. Carefully flip using a large plate or pan lid, then cook the other side for another 8–10 minutes until crisp and richly golden around the edges.
Drain and Serve
Transfer to kitchen paper to drain excess oil and serve immediately while hot and crisp.
Add the Eggs
Top the cooked potato rosti with two softly cooked eggs, either fried or poached, then cut the rosti into wedges before serving. Finish with a light sprinkle of parsley and black pepper.
Final Touch
Sprinkle with a little extra salt before serving if desired.

Recipe Tips
- Grate the potatoes just before cooking — they can discolour quickly if left exposed to air.
- Squeeze out as much moisture as possible — excess water will prevent the rosti from crisping up.
- Use a non-stick pan to avoid the rosti sticking and breaking apart.
- Adjust the heat as needed — too high and the outside will burn before the inside is cooked.
- Serve immediately — rosti is best enjoyed hot and crispy.
- For extra crispy edges like the photo, allow some strands of potato to spread slightly around the edge of the pan while cooking.
Healthy Alternatives / Variations
- Add grated cheese to the potato mixture for a cheesy twist.
- Include chopped herbs like parsley or chives for added flavour.
- Mix in some cooked bacon bits for a smoky taste.
- Try sweet potatoes instead of regular potatoes for a different flavour.
- Add a pinch of paprika for a subtle spicy kick.
Ingredient Substitutions
- Use shallots instead of onions for a milder flavour.
- Replace plain flour with cornflour for a gluten-free option.
- Swap vegetable oil for olive oil for a different taste.
- Use ghee instead of butter for a richer flavour.
