Silky Spanish croquettes filled with a rich, creamy béchamel infused with sautéed wild woodland mushrooms and garlic, enveloped in a crunchy breadcrumb crust.
Melt 1 tbsp butter in a skillet. Sauté minced garlic and chopped mushrooms over high heat for 6-7 minutes until all mushroom water evaporates and mushrooms are deeply browned. Set aside.
Melt remaining butter in saucepan, add flour and cook roux for 2 minutes. Slowly pour in warm milk, whisking continuously. Add sautéed mushrooms, nutmeg, salt, and pepper. Simmer for 12 minutes until thick and pulling away from edges. Chill dough for 4 hours.
Shape chilled dough into croquettes, dip in beaten egg, and coat thoroughly in breadcrumbs.
Deep fry in hot oil at 180°C for 2-3 minutes until golden brown and crispy. Serve warm.
