Step 1

For the burgers:

Step 2

In a small saucepan over medium-high heat, add the butter and scallions. Cook until the scallions have softened, 2 to 3 minutes, stirring occasionally. Turn heat off and set aside.

Step 3

In a large bowl, mix together the chopped shrimp, cheddar cheese, panko breadcrumbs, lime juice, smoked paprika, egg, garlic, salt, ground black pepper and the cooked scallion mixture until just combined. Form into 4 equal-sized patties (about 1/2-inch thick) and place on a parchment paper-lined plate. Transfer to the fridge to firm up, 5 to 10 minutes.

Step 4

For the spicy mayo:

Step 5

In a small bowl, whisk together the mayonnaise, hot sauce, lemon juice, onion powder and garlic powder. Set aside.

Step 6

Heat a large nonstick skillet on medium-low heat. Evenly spread about 1 teaspoon of the spicy mayonnaise on each cut side of the buns and place cut-side down onto the hot skillet. Cook until toasted and warmed through, about 2 minutes, making sure to keep an eye on them. Remove the buns from the pan and transfer to a plate.

Step 7

To assemble:

Step 8

In the large nonstick skillet over medium heat, add the canola oil. When the oil is hot, add the shrimp patties and cook until golden brown and crispy, about 3 minutes on each side.

Step 9

Spread your desired amount of the remaining spicy mayo on the bottom half of the toasted buns. Top each with a shrimp patty, iceberg lettuce and the top bun. Serve immediately.
