Spanish Flag Tortilla: A Potato Omelette with Caramelized Red Pepper and Garlic
This Spanish Flag Tortilla is a recipe that grew naturally out of the way we like to cook at home. We have always loved the combination of sweet red pepper, intense garlic, and tender potatoes, so over time this became one of our favorite ways to prepare a Spanish potato omelette. The technique is simple, but each ingredient brings something different to the finished dish: the red pepper is gently cooked until soft and naturally sweet, the garlic adds a deeper and more aromatic flavor, and the potatoes provide the comforting texture and substance that make a tortilla so satisfying.
The result is a particularly juicy and flavorful tortilla, with a wonderful contrast between the sweetness of the caramelized pepper, the savory intensity of the garlic, and the soft, tender potatoes bound together with eggs. Because the pepper releases additional moisture as it cooks, this version is slightly softer and more delicate than a traditional potato-only tortilla, but that extra juiciness is precisely part of what makes it so delicious.
The Spanish Flag presentation came from wanting to have a little fun with a recipe that is already deeply connected to Spanish cooking. Instead of mixing all the pepper into the tortilla, we reserve two long, wide strips and gently caramelize them separately while preparing the rest of the ingredients. Once the golden tortilla is ready, the strips are placed across the top to create the red stripes of the Spanish flag against the golden surface. It is a simple idea, but it gives this family favorite a playful presentation and makes it especially fun to serve.
In the end, this is still a comforting homemade tortilla de patatas at heart—simple ingredients, a familiar cooking method, and flavors that work beautifully together. But the sweet red pepper, aromatic garlic, and colorful Spanish flag presentation give our family’s version its own personality. It is the kind of recipe that proves how a small variation on a classic can become something uniquely yours.
Ingredients
| Metric Amount | Imperial Amount | Core Ingredient | Preparation |
| 800 g | 1.8 lb | Potatoes | Medium-sized, peeled, and cut into thin slices |
| 1 unit | 1 unit | Red bell pepper | Cleaned, cored, two-thirds cut into 1–2 cm pieces, one-third reserved in long wide strips |
| 4 units | 4 units | Garlic cloves | Peeled and finely chopped |
| 5–6 units | 5–6 units | Eggs | Large, fresh |
| 90 ml | 6 tbsp | Extra virgin olive oil | Divided for cooking and caramelizing |
| 5 g | 1 tsp | Salt | Fine sea salt |
Instructions
1. Prepare the Red Pepper
Wash the red bell pepper, remove the seeds, and divide it into two parts. Cut approximately two-thirds of the pepper into small pieces, about 1–2 cm (½–¾ inch) in size.
Cut the remaining third into two long, wide strips. These strips will later be used to create the Spanish flag-inspired decoration on top of the tortilla.
Peel the potatoes and cut them into thin slices. Peel and finely chop the garlic cloves.
2. Gently Caramelize the Pepper Strips
Add the two long pepper strips to a large non-stick skillet with just a few drops of olive oil. Cook them gently over low heat while you prepare the potatoes and the remaining ingredients.
Turn the strips occasionally and allow them to soften slowly, release their natural juices, and become glossy and lightly caramelized. Once they are tender, carefully remove them from the skillet and set them aside.
3. Cook the Red Pepper and Garlic
Add the remaining olive oil to the same skillet and add the chopped red pepper. Cook over medium-low heat for several minutes, allowing it to soften and release some of its natural juices.
This is the moment to add the finely chopped garlic. Do not add the garlic before the pepper has started releasing its juices. Garlic cooks very quickly and can easily become toasted and bitter if added too early. Once the pepper has softened and released some moisture, the juices help protect the garlic while it releases its aroma into the oil and vegetables.
Cook the garlic with the pepper for about 1–2 minutes, stirring frequently.
4. Cook the Potatoes, Pepper, and Garlic
Add the sliced potatoes and salt to the skillet and carefully stir everything together.
Cover the skillet and cook over medium-low heat, approximately 4 out of 9, for about 25 minutes. The potatoes should cook gently in the covered skillet rather than being deep-fried.
The lid is important because the trapped heat and steam help the potatoes become tender while the oil allows some of their surfaces to lightly brown. Turn the potato mixture carefully halfway through cooking so that different pieces come into contact with the bottom of the skillet.
This creates a lovely combination of textures: some potatoes become lightly toasted and golden at the edges, while the covered skillet keeps the rest soft and tender. Keep the heat moderate and avoid allowing the potatoes or garlic to burn.
5. Combine the Potato Mixture with the Eggs
Beat the eggs in a large bowl. Add the cooked potato, pepper, and garlic mixture and gently stir until all the ingredients are evenly coated with egg.
Let the mixture rest for a few minutes if desired. This allows the eggs to begin coating the potatoes and helps the flavors come together.
6. Cook the Tortilla
Heat the skillet over medium-high heat. Add a little more olive oil if necessary, then pour in the egg and potato mixture.
Spread the ingredients evenly and cook until the bottom and outer edges have set and developed a firm golden crust. This usually takes about 4–5 minutes, depending on the size of the skillet and the desired consistency.
Because the red pepper releases additional moisture, this tortilla is particularly juicy and more delicate than a classic potato-only tortilla. Do not try to flip it too early. Allow the outside to cook properly and form a firm crust before turning it.
Place a large plate or lid over the skillet and carefully flip the tortilla. Slide it back into the skillet and cook the other side for another 2–3 minutes, or until it reaches your preferred consistency.
Transfer the tortilla to a serving plate.
7. Create the Spanish Flag Presentation
Place the two reserved caramelized red pepper strips horizontally across the golden surface of the tortilla, creating the two red stripes of a Spanish flag-inspired presentation.
The result is a golden, juicy potato omelette with a beautiful contrast of color and a presentation that gives this family recipe its distinctive character.
Chef’s Notes for Spanish Flag Tortilla
Why Is the Garlic Added After the Pepper? The garlic is finely chopped and cooks very quickly. If it is added before the pepper has released moisture, it can become toasted too quickly and develop a bitter flavor.
Adding the garlic once the chopped pepper has softened and released some of its natural juices creates a more gentle cooking environment. The garlic can then release its intense aroma into the oil without burning.
Why Is This Tortilla So Juicy? The red pepper naturally contains a considerable amount of water. As it cooks, it releases some of that moisture into the skillet and into the potato mixture.
This gives the finished tortilla a particularly juicy interior and contributes to its wonderful flavor. However, it also means that the tortilla is softer and more delicate than a traditional tortilla made only with potatoes and eggs.
Take Your Time Before Flipping The most important moment is the first flip. Because of the additional moisture from the red pepper, the center of the tortilla may remain quite soft while the outside is cooking.
Wait until the bottom and outer edges have properly set and formed a firm crust. A premature flip can cause the softer interior to break apart.
Common Mistakes to Avoid Spanish Flag Tortilla
Adding the Garlic Too Early: The finely chopped garlic can burn quickly. Wait until the chopped red pepper has softened and released some of its juices before adding it.
Cooking the Potatoes Over Excessively High Heat: The potatoes need time to become tender. Medium-low heat and a covered skillet allow them to cook gently while some surfaces develop lightly toasted edges.
Flipping the Tortilla Before the Crust Has Set: This version is juicier than a classic potato-only tortilla. Make sure the outside is sufficiently cooked and firm before attempting to turn it.
Burning the Pepper or Garlic: The aim is to develop sweetness and depth of flavor, not dark, bitter flavors. Keep the heat moderate and stir the ingredients as needed.
Variations on Spanish Flag Tortilla
Green Pepper and Onion Tortilla: For a sweeter, more traditional vegetable variation, replace the red pepper with green pepper and add thinly sliced onion. Cook both gently in extra virgin olive oil until soft and lightly caramelized before adding the garlic and potatoes. The onion and slowly cooked pepper create a naturally sweet flavor that works beautifully with the tender potatoes and eggs. This version is especially delicious when you enjoy the softer, sweeter side of Spanish home cooking.
Traditional Spanish Potato Omelette: For a simpler and more traditional version, leave out the red pepper and garlic and prepare a classic Spanish tortilla with just potatoes, eggs, extra virgin olive oil, and salt. This is the perfect option if you want to experience the classic combination of tender potatoes and eggs at its most simple and authentic.(Recipe here)
Pumpkin and Potato Tortilla: For a seasonal variation, replace part of the potatoes with pumpkin. Pumpkin brings a naturally sweet flavor and a soft, creamy texture that works surprisingly well with eggs and potatoes. The result is a colorful, comforting tortilla with a gentle sweetness and a beautifully tender interior. (Recipe here)

Spanish Flag Tortilla: A Potato Omelette with Caramelized Red Pepper and Garlic
In our home, we love the combination of sweet red pepper, strong garlic, and tender potatoes. Over time, this became one of our favorite ways to make tortilla de patatas. The Spanish flag presentation came naturally from the ingredients themselves: the golden tortilla forms the central band, while roasted red pepper creates the two red stripes.
Ingredients
- 4–5 medium potatoes (about 800 g / 1¾ lb)
- 1 red bell pepper, with approximately one-third reserved for decoration
- 4 garlic cloves
- 5–6 eggs
- 6 tablespoons extra virgin olive oil
- 1 teaspoon salt
Instructions
Prepare the Red Pepper
Wash the red bell pepper, remove the seeds, and divide it into two parts. Cut approximately two-thirds of the pepper into small pieces, about 1–2 cm (½–¾ inch) in size.

Garlic cooks very quickly and can easily become toasted and bitter if added too early. Once the pepper has softened and released some moisture, the juices help protect the garlic while it releases its aroma into the oil and vegetables.
Cook the garlic with the pepper for about 1–2 minutes, stirring frequently.
Cook the Potatoes, Pepper, and Garlic
Add the sliced potatoes and salt to the skillet and carefully stir everything together.
