The Spanish potato omelet, also known as tortilla de patatas, is a classic dish that combines simple ingredients to create a flavorful and satisfying meal. This traditional Spanish recipe is perfect for breakfast, lunch, or dinner and can be enjoyed warm or at room temperature. The combination of tender potatoes and sweet onions enveloped in fluffy eggs makes it a versatile and delicious option for any occasion.
Most of the ingredients for this recipe are commonly found in any kitchen. However, you might want to ensure you have enough olive oil on hand, as it plays a crucial role in cooking the potatoes and onions to perfection. If you don't usually stock olive oil, make sure to pick up a good quality one at the supermarket for the best flavor.
Ingredients for Spanish Potato Omelet

Eggs: Bind the ingredients together and create a fluffy texture.

When cooking the potatoes and onions, ensure they are evenly sliced to promote uniform cooking. Use a mandoline slicer for precision.

How to Store or Freeze This Dish
Allow the Spanish potato omelet to cool to room temperature before storing. This prevents condensation, which can make the omelet soggy.
For short-term storage, place the omelet in an airtight container. Refrigerate for up to 3 days. This keeps the potatoes and eggs fresh and flavorful.
To freeze, wrap the omelet tightly in plastic wrap, then place it in a freezer-safe bag or container. Label with the date. The omelet can be frozen for up to 1 month.
When ready to eat, thaw the omelet in the refrigerator overnight. This ensures even defrosting without compromising texture.
Reheat in a skillet over low heat or in the microwave. If using a microwave, cover with a damp paper towel to retain moisture. Heat until warmed through.
For best results, avoid reheating multiple times as this can dry out the omelet and alter its taste.
How to Reheat Leftovers
For a quick and easy method, use the microwave. Place a slice of the Spanish potato omelet on a microwave-safe plate. Cover it with a damp paper towel to retain moisture. Heat on medium power for about 1-2 minutes, checking halfway to ensure it doesn't dry out.
If you prefer a crispier texture, opt for the oven. Preheat your oven to 350°F (175°C). Place the omelet on a baking sheet lined with parchment paper. Cover it loosely with aluminum foil to prevent it from drying out. Bake for about 10-15 minutes, or until heated through.
For a method that retains the original texture, use a stovetop. Heat a non-stick skillet over medium-low heat. Add a small amount of olive oil or butter. Place the omelet slice in the skillet and cover with a lid. Heat for about 5-7 minutes, flipping halfway through to ensure even reheating.
If you have an air fryer, this can be a quick and efficient method. Preheat the air fryer to 320°F (160°C). Place the omelet slice in the basket and heat for about 5-6 minutes, checking halfway to ensure it heats evenly without becoming too crispy.
