Ingredients

• 4 medium (about 800g) Russet potatoes
• 1 medium Yellow onion
• 3 tablespoons Unsalted butter
• 2 tablespoons Vegetable oil
• 1 teaspoon (or to taste) Salt
• 0.5 teaspoon (or to taste) Black pepper
• 1 tablespoon (chopped, optional for garnish) Fresh parsley

Directions

Step 1

Peel the potatoes and place them in a large pot of cold water to prevent browning.

Step 2

Bring the pot of water to a boil, then reduce to a simmer and cook the potatoes for about 8 minutes. They should still be firm but slightly tender. Drain and let them cool completely.

Step 3

Once the potatoes are cool, grate them using the large holes of a box grater. Set aside.

Step 4

Peel and thinly slice the onion into half moons.

Step 5

In a large nonstick skillet, heat 1 tablespoon of butter and 1 tablespoon of vegetable oil over medium heat.

Step 6

Add the sliced onion to the pan and cook for 5-7 minutes, stirring occasionally, until golden and caramelized. Remove the onions from the skillet and set aside.

Step 7

In the same skillet, add another tablespoon of butter and 1 tablespoon of vegetable oil. Add half of the grated potato and gently press it down into a flat, even layer.

Step 8

Spread the caramelized onions evenly across the layer of potatoes. Then, add the remaining grated potatoes on top and press down gently to form a compact cake.

Step 9

Season the top with salt and black pepper.

Step 10

Cook over medium heat for 10 minutes, or until the bottom is golden brown and crisp. Use a spatula to gently lift and check occasionally.

Step 11

Place a large plate or lid over the skillet. Carefully invert the rösti onto the plate. Add the remaining tablespoon of butter to the skillet, then slide the rösti back into the pan, uncooked side down.

Step 12

Cook for another 8-10 minutes, or until the second side is golden and crisp.

Step 13

Once cooked, slide the rösti onto a serving plate. Garnish with freshly chopped parsley if desired. Serve hot and enjoy!
