Learn how to make Spanish omelette with Joe Howley, the head chef of The Salt Yard restaurant in London.

Spanish omelette is a classic omelette but with a Catalonian twist and is a wholesome and tasty meal that all the family can enjoy. It is one of the most popular omelette recipes (opens in new tab) and is a great way to use up leftover veg too. 

The key, Joe Howley (opens in new tab) says, is to get your potatoes nice and crispy before adding them to the egg mixture. He explains this works well because it helps dry out the potatoes a little bit, allowing them to soak up more of the lovely egg mixture, giving it the perfect texture. The only other ingredient, besides the egg and potatoes, is an onion – slowly fried for a deliciously sweet flavour. 

Although this recipe uses oil, as it is the lighter option and the Spanish traditionally use oil, you can use butter too. By using butter, your Spanish omelette will have a richer texture and more decadent flavour.

It is delicious served hot or cold – so you can whip it up for dinner or even a packed lunch. Joe’s recipe serves four, so just make sure to scale up or down depending on how many people you want to feed.

Preparation: Before cooking, it is essential that you make sure you have the right frying pan. Omelettes have to be cooked to perfection, especially a thick Spanish omelette, as all the eggs in the mixture must be cooked thoroughly. 

Use a 6-12 inch frying pan, either aluminum, enameled cast iron, or stainless steel with a non-stick finish. It also should have a long handle and a flat bottom, so that you can easily remove your omelette. 

We'd also recommend using fresh free-range eggs, as this will help to make your Spanish omelette super fluffy and light. Use the egg float test (opens in new tab)method to choose your freshest eggs. By far one of the best Spanish recipes (opens in new tab).

FAQs about cooking a Spanish omelette

How to cook an omelette in the air fryer

Cooking an omelette in an air fryer is easy - and a great option when you've got other things to be cracking on with. Simply follow Joe's Spanish omelette step-by-step recipe above and then simply follow our air fryer instructions below to cook omelette to perfection in an air fryer.

Omelettes are already rich in protein and omega-3 fatty acids, but cooking them in an air fryer just cuts down the fat count too as you won't need to use any butter or oil, only a light cooking spray to ensure the omelette doesn't stick when cooking.

  1. Grease a 7" round cake pan with cooking spray.
  2. Heat your air fryer to 180°C.
  3. Pour your omelette mix into your cake pan.
  4. Pop into air fryer and cook for 6-10 minutes.
  5. If you find there is still too much runny egg at the bottom, pop it back into the air fryer for a couple of minutes.
  6. Remove from the air fryer carefully and garnish it with a drizzle of oil.

How to cook an omelette in the oven

This may be deemed as an unusual way to make an omelette, but this is the perfect solution for all those who love to set and forget.

We suggest using a large round oven dish when making an omelette in the oven. Choose a non-stick and drizzle the pan with oil or spread with a thin layer of butter before adding the egg mixture.

Simply follow Joe's Spanish omelette recipe step-by-step above and then instead of adding the mixture to the frying pan to cook, add it to an ovenproof dish:

  1. Set your oven to 180C.
  2. Grease your baking dish with cooking spray, oil or butter.
  3. Pour your mixture in and cook for 25-30 minutes. Until golden on top.

Can you keep leftover cooked omelette?

Surprisingly you can keep leftover cooked omelette, you can even freeze it if needed.    Best kept for up to 2 days in the fridge, omelette needs to be reheated thoroughly before serving again. 

The best ways to reheat omelettes are by microwaving them for up to 3 seconds or putting them in the oven for 5 minutes at 180°C. Perfect for a mid-week lunch.

When it comes to freezing, use an air-tight container or sealed bag which is freezer safe. Let the Spanish omelette cool completely before popping leftovers in the fridge or freezer.
