One ingredient you might not always have on hand is olive oil. It's essential for achieving the authentic flavor and texture of the Spanish potato omelet.

Ingredients For Spanish Potato Omelet Recipe
Potatoes: These form the base of the omelet, providing a hearty and filling texture.
Onion: Adds a sweet and savory flavor that complements the potatoes.
Eggs: Bind the ingredients together and give the omelet its structure.
Olive oil: Used for cooking the potatoes and onion, adding richness and depth to the dish.

Technique Tip for This Recipe
When cooking the potatoes and onions, ensure they are sliced uniformly to promote even cooking. Use a mandoline slicer for precision. This will help achieve a consistent texture throughout the omelet. Additionally, when flipping the omelet, place a large plate over the pan, invert the pan to transfer the omelet onto the plate, then slide it back into the pan to cook the other side. This technique minimizes the risk of breaking the omelet.

How to Store / Freeze This Dish
Allow the Spanish potato omelet to cool completely at room temperature before storing. This prevents condensation, which can make the omelet soggy.
For short-term storage, place the omelet in an airtight container or wrap it tightly with plastic wrap. Store it in the refrigerator for up to 3 days.
If you plan to freeze the omelet, cut it into individual portions. This makes it easier to thaw and reheat only what you need.
Wrap each portion tightly with plastic wrap, then place them in a resealable freezer bag. Label the bag with the date to keep track of freshness.
When ready to eat, thaw the omelet portions in the refrigerator overnight. This gradual thawing helps maintain the texture and flavor.
Reheat the omelet in a non-stick pan over low heat, or use a microwave. If using a microwave, cover the omelet with a damp paper towel to retain moisture.
For an extra touch of freshness, garnish the reheated omelet with chopped parsley or a sprinkle of sea salt before serving.
Avoid reheating the omelet multiple times, as this can lead to a rubbery texture. Reheat only the portions you plan to consume immediately.
