The short menu makes choices simple; the kitchen focuses on a handful of strongly executed dishes, which is ideal for diners who want honest, ingredient-led food without a long tasting ritual.

Masta positions itself for food lovers seeking culinary clarity and a coastal setting just steps from Zarautz beach. Led by Javier Ochoa and Garikoitz Arruabarrena, the kitchen keeps the cooking direct and flavorful.

Wild boar meatballs arrive richly seasoned and slow braised, offering gamey depth with a silky sauce that carries smoked paprika and herb notes. Mushrooms with shrimps and yolk combine sautéed local fungi, tender shrimp, and a soft egg yolk to bind umami and marine snap. Stuffed peppers are served as a reimagined classic, filled with a savory mix of rice or local minced meat, then gently roasted and finished with a dribble of good olive oil. Seasonal market fish appears regularly, roasted or simply grilled to highlight fresh texture and ocean flavor; ask for the day’s catch. Vegetarian seasonal plates rotate with produce harvests, often leveraging charred vegetables, creamy legumes, and cured Basque cheeses. The kitchen favors direct techniques—grilling, braising, and gentle roasting—so ingredients read clearly on the plate. Dining at Masta is casual but attentive.
