Keto Tortilla Española Recipe
During college, I studied abroad in Córdoba, located in the Andalucía region of southern Spain. My school arranged boarding with an older woman nearby who gave me a crash course in Spanish cooking.
We usually ate the “tortilla española” at room temperature with a slice of bread for lunch. It’s a plain dish but absolutely delicious in its simplicity.
The real Spanish omelette contains potatoes, but that’s not allowed for us on a keto diet!
No problem, though, because we can use cauliflower instead. I promise, cauliflower is a flawless substitution – you won’t miss the carbs.
Turnips, parsnips, and radish could also work, but I use cauliflower for just about all the low-carb swaps I can.
Take a look at these other ideas, and you’ll see how versatile it is.

Ingredients
Cauliflower – Cut the head into florets. You want small bite-sized pieces to best replicate the size of diced potato. You can also substitute with radish slices (sauté them first before adding to the egg mixture) which closely resembles sliced potatoes.
Olive oil – For the most authentic result, you have to use olive oil! It’s a beautiful flavor and such a traditional ingredient in Spanish cuisine. However, a suitable alternative cooking fat like butter, ghee, or coconut oil will work just as well if you do not have olive oil on hand.
Onion – White or yellow onions are best for their mellow sweetness, but red ones won’t ruin the dish either. Slice thinly!
Eggs – Opt for free-range, pastured eggs or raise them yourself!
Salt – A pinch to enhance the flavor. I typically choose one of these different types of gourmet salt.
Directions
First, steam the cauliflower in a small saucepan for 5-7 minutes until tender. Remove from heat and set aside.
Then, add 2 tablespoons of olive oil to a 10-inch frying pan and warm up over medium heat.
Next, sauté onions for 3 minutes in oil until translucent. Add the cauliflower and continue cooking for another 2 minutes.
Whisk eggs and salt in a bowl while the onions cook. Then, mix onions and cauliflower with the eggs.
Now, add the remaining oil to the pan. Pour egg mixture in and cook for 5-7 minutes over medium heat. Continue until the edges are set and the center appears firm.
The secret of this recipe is finding a balance between your heat, the thickness of the pan, and the density of the eggs. Monitor it so you don’t overheat, thus burning the bottom of the eggs before the top cooks through enough to flip it over.
Once eggs are firm, place a large plate over the opening of the pan. Hold it securely and flip the tortilla onto the plate.
The balancing act continues as you place the pan back on the stove and gently slide the omelette back into the pan.
Phew, the hard part is over! Continue cooking the second side for 2 minutes, until golden brown.
Finally, remove from the heat, cut into wedges and serve hot or cool to room temperature.
Serve the Spanish omelette standing alone or with a fresh garden salad. It’s also nice on a piece of keto bread.
Save your leftovers because cold portions are even better the next day. Pack it up for an easy prep lunch!
