Every bar in Barcelona has its own patatas bravas, and locals are specific about which version they prefer — the debate over whether the sauce should be red (tomato-chili) or white (alioli) or both-together consumed as a single drizzle is ongoing and semi-serious. The potatoes themselves are non-negotiable: medium-diced, fried twice (once to cook through, once to crisp) until the edges are shatteringly crispy while the inside stays fluffy. The salsa brava is the personality of the dish: some versions use smoked paprika and tomato into a thick paste, others are aioli-forward, and the Madrileño version (patatas bravas madrileñas) is lighter and vinegar-spiked. In Catalonia, both sauces often arrive together — the red poured over and alioli dotted alongside.
Preheat your oven to 425°F (220°C).
Spread the potato cubes on a baking sheet and drizzle with olive oil. Toss to coat evenly.
Season with salt.
Roast the potatoes in the preheated oven for about 25-30 minutes, or until they are golden brown and crispy, turning them halfway through.
While the potatoes are roasting, heat the olive oil in a skillet over medium heat.
Add the finely chopped onion and cook until it becomes soft and translucent.
Stir in the minced garlic, smoked paprika, cayenne pepper, and ground cumin. Cook for another minute until fragrant.
Add the crushed tomatoes, tomato paste, and sugar. Stir to combine.
Season with salt and pepper to taste.
Let the sauce simmer for about 10-15 minutes, or until it thickens slightly.
Stir in the red wine vinegar and adjust seasoning if needed.
Transfer the roasted potatoes to a serving dish.
Spoon the bravas sauce over the potatoes.
Optionally, garnish with chopped fresh parsley.
Fried potato chunks with spicy tomato sauce and/or alioli; Spain's most universal tapa.
Madrid origin (1960s tapas bar culture); Catalan version has evolved independently with dual-sauce service.
Starchy potatoes (Maris Piper or similar), sunflower oil for frying, smoked paprika, tomato, garlic, and vinegar.
Fry twice: first at 140°C until cooked through (10 min), then at 190°C until crispy (3 min) — double-frying prevents soggy potatoes.
Cerveza (cold beer) or vermouth on the rocks; part of a broader tapas spread.
