Ingredients

• 8 large eggs
• 0.25 cups heavy cream
• 2 tablespoons unsalted butter
• 2 tablespoons olive oil
• 1 medium (thinly sliced) yellow onion
• 2 medium (peeled and thinly sliced) Yukon Gold potatoes
• 1 cup (shredded) Swiss cheese
• 1 teaspoon salt
• 0.5 teaspoons black pepper
• 2 tablespoons (chopped, for garnish) fresh parsley

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

In a large oven-safe skillet (preferably cast iron), heat 1 tablespoon of olive oil and 1 tablespoon of unsalted butter over medium heat.

Step 3

Add the thinly sliced onions and a pinch of salt. Cook for 10-12 minutes, stirring occasionally, until the onions are soft and caramelized. Remove them from the skillet and set aside.

Step 4

In the same skillet, heat the remaining tablespoon of olive oil and butter. Add the thinly sliced potatoes in a single layer. Sprinkle with a pinch of salt and black pepper, then cook for 8-10 minutes, turning occasionally, until the potatoes are tender and lightly golden. Remove from heat.

Step 5

While the potatoes are cooking, whisk together the eggs, heavy cream, 1 teaspoon of salt, and 1/2 teaspoon of black pepper in a large mixing bowl.

Step 6

Return the caramelized onions to the skillet and spread them evenly over the potatoes.

Step 7

Pour the egg mixture over the potatoes and onions, tilting the skillet slightly to ensure the eggs coat all the ingredients evenly.

Step 8

Sprinkle the shredded Swiss cheese evenly over the top of the egg mixture.

Step 9

Transfer the skillet to the preheated oven and bake for 18-20 minutes, or until the eggs are set and the top is lightly golden. Check for doneness by inserting a knife into the center; it should come out clean.

Step 10

Remove the skillet from the oven and let the frittata cool for 5 minutes before slicing.

Step 11

Garnish with freshly chopped parsley and serve warm.
