Step-by-Step Cooking Directions
Prepare the Ingredients
Start by prepping your vegetables. Peel the potato and onion. Use a mandoline slicer or sharp knife to cut both into thin, uniform slices. Thin slices ensure even cooking and create beautiful, tender layers in the finished frittata.
Cook the Potato and Onion
Heat 2–3 tablespoons of olive oil in a non-stick or cast-iron skillet over medium heat. Once hot, add the potato and onion slices.
Season with salt and freshly cracked black pepper. Stir occasionally to prevent burning, but let them sit long enough to develop a golden edge. Cook for about 10–15 minutes, or until the potatoes are soft and lightly crisped and the onions are caramelized and golden.
Prepare the Egg and Cream Mixture
In a medium bowl, crack the eggs and pour in the liquid cream. Add a pinch of salt and pepper. Whisk until the mixture is smooth, airy, and pale yellow. This blend creates a rich, custardy texture once cooked.
Combine and Set the Frittata
Reduce the skillet heat to low. Spread the sautéed potatoes and onions evenly across the bottom of the pan.
Pour the egg and cream mixture over the top. Do not stir. Cover the skillet with a lid to trap heat and moisture, allowing the eggs to slowly cook and set without browning too quickly. Let cook for about 5–7 minutes, or until the edges are firm and the top begins to set.
Finish and Serve
Once the eggs are nearly set, remove the lid and cook uncovered for another 2–3 minutes if needed, just until the top is cooked through.
Slide the frittata gently onto a plate or cutting board. Garnish with fresh parsley or chives for a bright finish.
Slice into wedges and serve hot or warm. This frittata also tastes wonderful at room temperature, making it perfect for make-ahead meals.

The Origins and Popularity of the Recipe
The frittata is an iconic Italian dish that translates loosely to “fried” or “cooked in a pan.” Traditionally made with eggs and a variety of leftovers or fresh vegetables, the frittata is similar to an omelet but cooked more slowly and often finished in the oven.
This version—featuring tender potatoes and onions—borrows from the Spanish tortilla as well, combining creamy eggs with sliced potatoes for a luxurious and hearty texture. Its simplicity and versatility have made the frittata a beloved dish across cultures, with regional versions served in cafes, homes, and brunch tables worldwide.

Absolutely. Add ¼ to ½ cup of shredded cheese to the egg mixture or sprinkle on top before cooking.
3. What’s the best cream to use?
20% fat liquid cream works well, but you can also use half-and-half or heavy cream for extra richness.

9. Can I make this dairy-free?
Use a plant-based cream substitute like oat cream or almond milk, and be sure your pan is well-oiled to prevent sticking.
