This Spanish tortilla recipe gives the classic combination of potatoes, onions and eggs a luxurious twist by cooking them in rendered Wagyu fat. The result is a rich, deeply flavoured tortilla with tender potatoes, caramelised onions and a softly set centre.
Also known as tortilla española or Spanish omelette, this traditional dish relies on just a handful of ingredients. Here, Wagyu fat replaces the more conventional cooking fat, adding an extra layer of richness while keeping the simplicity that makes a good potato tortilla so satisfying.
The Wagyu fat is slowly rendered before being used to cook the onions and potatoes. Don't discard any leftover fat after making the tortillas – it can be strained, refrigerated and reused.
This mixture makes two tortillas and requires a small non-stick frying pan.

Ingredients
- 300ml Wagyu fat rendered from 500g
- 2 onions, thickly sliced
- 700g waxy potatoes, thickly sliced
- 6 eggs
Directions
Method
Step 1, To render the Wagyu fat, chop it into 1-inch chunks and add it to a large high sided frying pan, with around an inch of water.
Step 2, Set the pan over low heat and cook for around 3 hours, stirring every so often. The fat is ready when all the water has evaporated and the fat pieces are making a lot of crackling noises. Strain the fat into a clean container.
Step 3, Heat the Wagyu fat in a high sided pan and fry the onions until soft and beginning to caramelise. Remove using a slotted spoon and set aside.
Step 4, Repeat with the potatoes until the potatoes are completely soft.
Step 5, Combine the onions and potatoes in a bowl and mix in the eggs. Season really well with salt - more than you might think.
Step 6, Pour half of the mixture into a 19cm or other small non-stick frying pan and set it over a medium heat. Once it has set on the bottom, use a plate to turn it over and back into the pan.
Step 7, Cook until just set, so that the warm egg oozes out when it is cut. If you prefer a more set tortilla, cook for a little longer. Repeat with the other half of the mixture.
