Mushroom croquetas are the small-sized Spanish fritters that are prepared with a combination of a creamy béchamel base and diced and sautéed boletus mushrooms. The base is well chilled before it is shaped into round or cylindrical forms.

Each piece is coated in egg wash and breadcrumbs, then shortly deep-fried until golden and crispy. Boletus croquetas are often enriched with various spices and sautéed onions and are typically enjoyed as a ubiquitous Spanish tapas.
