Homemade Chilean Tuna Omelette Recipe
Preparation: 10 minutes
Cooking: 15 minutes
Servings: 2
Ingredients
- 200 g of canned tuna
- 2 scallion stalks, chopped
- 2 eggs
- 1 tablespoon of oil
- 1 tablespoon of flour (optional)
- Fine salt
- Black pepper
Instructions
- In a medium bowl, beat the eggs until smooth and foamy, add the finely chopped scallions, and mix. Set aside.

- Drain the tuna, flake it with a fork, and add it to the eggs. Season with salt and pepper and mix well. If you like, add a tablespoon of flour for a firmer omelette.

- Heat the oil in a large skillet over high heat, pour in the mixture, and swirl the pan to spread it evenly. Lower to medium heat and cook until the surface starts to bubble lightly, about 7 minutes.
- Flip it with the help of a flat plate and cook for about 3 more minutes until cooked through but not dry. Serve right away with fries, arroz primavera, or Chilean salad, as a starter or main course.
Additional Tips
Beat the eggs well
Beat until you see clear bubbles and a foamy texture before adding the tuna. The trapped air makes the omelette lighter instead of a dense block.
Flip at the right time
Flip when the surface starts to bubble lightly. If you wait until the top is dry, the bottom will burn, and if you flip too early, it will break.
Reduce the sodium
Rinse the drained tuna briefly in cold water before flaking it to remove much of the salt from the can.

Frequently Asked Questions (FAQs)
1. Is tuna in water or in oil better?
Tuna in water gives a firmer, leaner omelette, while tuna in oil adds juiciness that keeps it tender longer if you plan to eat it cold or take it to work.
2. How can I lower the sodium?
Drain the tuna and rinse it briefly in cold water before flaking it. This removes much of the salt without affecting the protein.
3. Can I add raw vegetables?
Yes, but sauté them first or cut them very finely. Thick raw vegetables release water while cooking and keep the egg from setting properly.
4. Why does it stick even in a nonstick pan?
The egg needs hot fat to set instantly. Make sure the oil is hot but not smoking before pouring in the mixture.
