Crispy Swedish root vegetable hash: finely diced potatoes, carrots, parsnips, celeriac, and red onions fried in butter until golden and caramelized, topped with a fried egg and pickled beetroot.
Dice potatoes, root vegetables, and onions into uniform 5mm cubes so they cook evenly together.
Melt butter and oil in a wide cast-iron skillet over medium-high heat. Add potatoes and root vegetables, frying undisturbed for 4 minutes to develop a crust.
Toss and stir in diced onions. Continue frying for 10-12 minutes until vegetables are golden brown, caramelized, and tender.
Season with salt and black pepper. Plate hot pyttipanna topped with a runny fried egg and pickled beetroot slices.
