Ingredient Essentials & Substitutions

Labeled ingredients for grilled redfish with lemon butter shrimp sauce in bowls and a plate on a white marbled background.
  • I used local redfish, also called red drum, for this recipe. I prefer boneless fillets over redfish on the half shell, with the scales still intact. However, you can also make this recipe with the latter type by grilling them scale-side down and then flipping them over for the finish. 
  • For best results, use medium-sized, roughly 36/40-count shrimp for the sauce. These are large enough to make an impressive presentation yet small enough to be enjoyed in bites along with the fish. 
  • Grab a couple of lemons for the juice and zest. They only take a few minutes to prep and are extremely important for the sauce.
  • I love and recommend Crystal hot sauce. You can also use Tabasco or Louisiana hot sauce. 

How to Make Grilled Redfish with Lemon Butter Shrimp Sauce

To start the recipe, use a wire brush to clean your grill grates of debris, then oil them lightly. Preheat the grill to medium-high heat. 

Then, season the shrimp with salt, black pepper, and cayenne.

Ingredients

For the Lemon Butter Shrimp Sauce

  • ยฝ pound peeled, deveined shrimp 36/40-count is ideal

  • 2 tablespoons lemon juice freshly squeezed
  • ยฝ teaspoon lemon zest
  • 1 tablespoon minced garlic
  • 1 tablespoon chopped fresh parsley leaves

For the Grilled Redfish

  • 2 tablespoons olive oil I love this one
  • 2 teaspoons onion powder
  • ยฝ teaspoon paprika
  • salt, black pepper, and cayenne to taste I used about ยผ teaspoon salt, โ…› teaspoon black pepper, and โ…› teaspoon cayenne

Instructions

  • Prepare a charcoal chimney or heat a gas grill to medium-high.
  • Season the shrimp and place in a shallow cast iron baking dish. Add the butter, lemon juice, lemon zest, garlic, parsley, and hot sauce to the dish.
  • Pour about ยฝ tablespoon of olive oil into a 9 x 13 baking dish. Sprinkle about ยผ of the onion powder, paprika, salt, black pepper, and cayenne pepper to taste into the bottom of the dish.

  • Cook the fish for about 3 minutes, then flip each fillet over carefully and cook for an additional 3 to 5 minutes, or until a digital thermometer inserted into the thickest part of each fillet reads at least 145 degrees Fahrenheit.
  • Transfer the redfish fillets to a heat-proof serving platter.

Notes

This dish keeps well covered in the fridge for up to 2 days. 
Save prep time by pouring the seasoned shrimp and remaining sauce ingredients into an airtight container or freezer bag and refrigerating overnight. 
You can make the sauce on the stove instead of the grill if desired. 
Too many seasonings can cause the fish to stick to the grill grates. So, I lightly season one side of the fish to give the fillet a better chance of staying in one piece throughout the necessary flip that often breaks them. Heavily seasoning one side also enhances the final presentation, in my opinion. 
Stay close to the redfish while grilling. The cooking time will depend on the thickness of the fillets, so even a minute of overcooking can make a drastic difference in taste and texture.
