Spiced tortilla
About this recipe
Spanish cooking flows from olive oil, garlic, paprika, and tomato — the matriz of the Mediterranean kitchen — applied across tapas, slow-cooked stews, and the seafood traditions of both coasts. Sherry vinegar and Spanish saffron supply most of the brightness and depth.
As a vegetarian dish, Spiced tortilla is meatless but not minimal — built around vegetables, pulses, dairy, and grains that anchor every cooking tradition's day-to-day repertoire.

Method
- step 1
- Heat the oil in a large frying pan. Fry the onion and half the chilli for 5 mins until softened. Tip in the spices, fry for 1 min more, then add the cherry tomatoes, potatoes and coriander stalks to the pan. Season the eggs well, pour over the top of the veg and leave to cook gently for 8-10 mins until almost set.
- step 2
- Heat the grill and flash the tortilla underneath for 1-2 mins until the top is set. Scatter the coriander leaves and remaining chilli over the top, slice into wedges and serve with a green salad.
Cooking notes
Most vegetable dishes scale linearly, but be mindful of pan crowding — vegetables that should brown will steam instead if packed too tightly.
For volume-to-weight conversions of any ingredient — flour, sugar, butter, salts — use the ingredient converter. To translate the recipe's oven temperature between °C, °F and gas mark, see the temperature converter.
When you scale this recipe up or down, remember that cooking time does not scale linearly. A doubled cake takes longer, but not twice as long; a doubled soup takes roughly twice as long. The cooking-time guide gives sensible starting estimates by dish geometry.
Scaling notes
Scaling Spiced tortilla
Spiced tortilla is written for around four servings as it stands on this page — scaling it up for a party or down for a meal-for-one is the small math problem most home cooks face every week. Here's how this particular dish responds to scaling, what changes linearly, and what doesn't.
Vegetarian recipes like Spiced tortilla are among the easiest to scale because most ingredients respond linearly to multiplication. The main constraints are pan capacity (crowding causes steaming, not the browning the recipe assumes) and seasoning intensity (use 1.5× the salt and spices when doubling, taste, adjust upward).
This recipe calls for eggs, which are the trickiest ingredient to scale to non-integer multiples. A US "large" egg weighs about 50 g; if a fractional scaling lands on, say, 1.5 eggs, beat one egg and weigh 25 g of the beaten mixture rather than guessing. The same goes for halving recipes — half an egg is 25 g of beaten egg, not a dramatic estimate.

Beyond the recipe
Substitutions & make-ahead — Spiced tortilla
Two things home cooks ask about most when they're outside the recipe's exact assumptions: what swaps work for which ingredients, and how the dish behaves when you make it ahead. Both depend on what Spiced tortilla is doing structurally — here's the practical version.
Substitution ideas
Eggs
For binding (cookies, quick breads, meatballs): 1 large egg ≈ 1 tbsp ground flaxseed + 3 tbsp water, rested 5 minutes until gelled — structurally closest to a real egg. For moisture without structure (cakes, brownies): ¼ cup unsweetened applesauce or mashed banana per egg, accepting some loss of rise.
For weight-based swaps and arbitrary quantities, the ingredient density converter and the cup-to-grams chart cover most pantry staples.
Make-ahead and storage
Vegetarian dishes like Spiced tortilla sit comfortably in the make-ahead window — they store and reheat better than meat-centric dishes. Refrigerate 3-4 days; freeze most pulse, grain, or cooked-vegetable preparations for up to 2 months. The exceptions are dishes with raw or barely-cooked elements (salads, fresh herbs, anything crispy) — those components should be added at serving time, not stored with the rest.
