Shrimp Size: For best results, use jumbo shrimp-sized 21/25 count per pound. They are big enough in size that they will stay juicy and don't become overcooked.
Breadcrumbs: Panko breadcrumbs are best for crispiness, though regular or homemade bread crumbs work equally well. Seasoned breadcrumbs require unseasoned kinds with added spices if desired, for more flavor.
Cornstarch vs. Flour: Cornstarch replaces moisture and creates a golden crispy crust. In the absence of cornstarch, flour can serve as a good substitute; however, the level of crispiness will vary.
Breading: Pat dry the shrimps. Cover with cornstarch, dip in a beaten egg, and lastly, cover with breadcrumbs. This will yield a superior coating. The breading will stick, and they will be crunchy.
Oven-baked: Bake at 400°F, spraying lightly with cooking spray before and after flipping to keep the shrimp light and crispy.
Serving Suggestions: These shrimp go amazingly well with chipotle mayo, garlic aioli, tartar sauce, or cocktail sauce.
