Rosti Filled Onions Recipes

Steps:

• Boil the potatoes in their skins for 20 minutes, drain and leave to cool. Peel them. Using a cheese grater, grate them into a large mixing bowl and sprinkle with salt.
• In a frying pan saute the bacon and onions. Strip the leaves off the sprigs of thyme into the pan. Add mushrooms and cook for about 5 minutes until soft. Combine with the potatoes and mix gently, taking care not to mash them too much.
• Heat oil in a frying pan and add 3 or 4 spoonfuls of the mixture, See cook's note*. Using a spatula, pat the mixture into a round flat cake. Brown it over a high heat. When the bottom side is cooked flip it over. Repeat with remaining potatoes to make 6 cakes.
• Put 1/2 tablespoon of butter and a slice of Gruyere on each cake and melt under a hot grill or broiler. Turn the Rosti onto a plate and serve with a green salad, if desired.

Steps:

• Heat oven to 200°C
• Place the onions on a baking tray, brush with olive oil, season, then cook for about 1 hr until golden and tender.
• Meanwhile, mix the potato and carrot together, then stir in the mustard and seasoning. Divide the mixture between the onions, then dot the top of each one with a little butter.
• Return the onions to the oven and cook for 15 mins until they are tender. Sprinkle with the cheese, then cook for a further 5 mins until the topping is golden and bubbling.

Steps:

• Squeeze any excess water out of the grated potatoes, then tip into a bowl and mix well with the egg, flour, baking powder, onion and chopped sage leaves. Season well. Heat 2 tbsp oil in a large non-stick frying pan over a medium heat, and spoon the mixture in to make 4 röstis, flattening them down with the back of a spoon into disc shapes. Cook for 5 mins each side until golden brown and crisp, then drain on kitchen paper. Can be made up to 8 hrs in advance and kept in the fridge (see tip).
• When ready to serve, heat the remaining 1 tbsp oil in the frying pan over a medium heat. Add the whole sage leaves and cook for 20 secs until crisp but still green. Drain on kitchen paper and top each rösti with a fried sage leaf.
