This traditional recipe is perfect for breakfast, lunch, or even dinner, and can be enjoyed hot or at room temperature. The combination of tender potatoes, sweet onions, and perfectly cooked eggs makes this dish a favorite in Spanish cuisine.
If you don't usually have olive oil in your pantry, it's essential for this recipe as it adds a rich flavor and helps cook the potatoes and onions to perfection. Make sure to pick up some olive oil when you visit the supermarket. Additionally, using fresh potatoes and onions will give the best results, so avoid pre-packaged or frozen options.

How to Store and Freeze Your Spanish Potato Omelet
Allow the Spanish potato omelet to cool completely at room temperature before storing. This prevents condensation, which can make the omelet soggy.
Once cooled, cut the omelet into individual portions. This makes it easier to reheat only what you need.
Wrap each portion tightly in plastic wrap or aluminum foil. This helps to maintain freshness and prevent freezer burn.
Place the wrapped portions in an airtight container or a freezer-safe zip-top bag. Label the container with the date to keep track of storage time.
Store the omelet in the refrigerator if you plan to consume it within 3-4 days. For longer storage, place it in the freezer where it can last up to 2 months.
To reheat, unwrap the portion and place it on a microwave-safe plate. Microwave on medium power for 1-2 minutes, or until heated through. Alternatively, reheat in a preheated oven at 350°F (175°C) for about 10 minutes.
For a crispier texture, reheat the omelet in a non-stick skillet over medium heat for a few minutes on each side.
Avoid reheating the omelet multiple times, as this can affect the texture and flavor. Only reheat the amount you plan to eat immediately.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover Spanish potato omelet on a baking sheet and cover it with aluminum foil. Heat for about 10-15 minutes or until warmed through. This method helps retain moisture and prevents the omelet from drying out.
Heat a non-stick skillet over medium-low heat. Add a small amount of olive oil or butter to the pan. Place the omelet in the skillet and cover it with a lid. Heat for about 5-7 minutes, flipping halfway through to ensure even warming. This method gives a slightly crispy texture to the omelet.
Use a microwave-safe dish and cover the omelet with a damp paper towel to prevent it from drying out. Microwave on medium power for 1-2 minutes, checking halfway through. Be cautious not to overheat, as this can make the eggs rubbery.
If you have an air fryer, preheat it to 300°F (150°C). Place the omelet in the air fryer basket and heat for about 5 minutes. This method gives a nice, slightly crispy finish to the omelet.
For a quick stovetop method, cut the omelet into smaller pieces and heat them in a non-stick skillet over medium heat with a bit of olive oil. Stir occasionally until heated through, which should take about 3-5 minutes. This method is great for maintaining the omelet's texture and flavor.
