These crispy-edged, soft-centered potato cakes are filled with caramelized onions and are a staple of Manx cuisine. Served warm with butter, they make a perfect side dish or light meal on their own. This manx potato and onion cakes is shaped by the home cooks who refined it across generations, balancing tradition with everyday practicality. It's the kind of midday dish that wakes you back up: textures that contrast, flavors that build. Home cooks return to it because the technique is forgiving once the order of operations clicks: build aromatics first, season in layers, and let time do the heavy lifting. The result lands somewhere between everyday and special — humble enough for a weeknight, generous enough for company.
Serves 4
Boil potatoes until tender, drain well and mash with 25g butter until smooth.
Sauté sliced onions in 25g butter over low heat for 15 minutes until golden and soft.
Mix mashed potatoes with onions, salt and pepper. Shape into 8 flat round cakes and coat lightly with flour.
Cook in a hot skillet for 4-5 minutes per side until golden and crispy.
Serve hot with butter melting on top.
Use floury potatoes for the best texture

Add cheese to the potato mixture
Mix in fresh herbs like parsley
