Cook sweet potatoes by roasting or boiling until tender. Let them cool slightly, peel, then mash until smooth with no lumps. Smooth texture ensures even croquette filling.
Combine mashed sweet potatoes with cheese, garlic, herbs, spices, egg, and breadcrumbs. Season well and mix thoroughly. Chill the mixture so it firms up for shaping.
Scoop portions and roll into small balls or ovals. Coat first in flour, then egg, and finally breadcrumbs or panko. This layered coating ensures crisp results.
Fry croquettes in hot oil until golden and crispy outside. Alternatively, bake at 400°F or air fry for a lighter version. Drain on paper towels after cooking.
Blend burrata with yogurt, lemon juice, olive oil, and herbs until smooth. Taste and adjust seasoning, then chill until serving time.
Mix chopped pistachios with lemon zest, parsley, and flaky salt. This topping adds brightness and texture to the final dish.
Arrange croquettes warm on a platter with dip in the center. Sprinkle pistachio crunch over the top just before serving.
