Xanthan Gum Free Spanish Tortilla Española
This classic Spanish egg-and-potato dish is the kind of recipe that looks impressive but comes together with just a handful of honest, wholesome ingredients. Silky Yukon Gold potatoes and sweet slow-cooked onion are folded into beaten eggs, then cooked low and slow into a thick, golden round that's equally at home on a tapas spread or a weeknight dinner table. The whole thing is naturally free of any gums or thickeners — no additives needed, because the starchy potatoes and eggs do all the binding work on their own. That slow simmer in olive oil is the real secret, coaxing the potatoes into melt-in-your-mouth tenderness before they ever meet the eggs. The flip is the one moment that demands a little confidence, but once you nail it, you'll feel like a proper Spanish home cook. Serve it warm, at room temperature, or even cold the next day — it genuinely gets better as it sits and the flavors settle together. A scatter of fresh parsley on top is optional, but it adds a bright, herby finish that makes the whole thing look as good as it tastes.

4 servings
- ½ cup extra virgin olive oil
- 1 ½ lb yukon gold potatoes, peeled and sliced ⅛-inch thick
- 1 medium yellow onion, halved and thinly sliced
- 1 tsp fine sea salt, divided
- 6 large eggs
- ¼ tsp freshly ground black pepper
- 2 tbsp fresh flat-leaf parsley, roughly chopped (optional)
Instructions
- 1
Heat the olive oil in a 10-inch nonstick skillet over medium-low heat until it shimmers. Add the potato slices and onion, season with ½ tsp of the salt, and stir gently to coat. Cook, turning the potatoes occasionally with a slotted spoon, until the potatoes are completely tender and yield easily when pressed with the back of a spoon, about 20–25 minutes. They should be soft but not browned.
- 2
Use a slotted spoon to transfer the potatoes and onion to a large mixing bowl, leaving as much oil behind in the skillet as possible. Reserve 2 tbsp of the cooking oil in the skillet and discard the rest (or save for another use).
