Step 1

Preheat an outdoor grill for medium heat and lightly oil the grate.

Step 2

Pour melted butter onto a plate. Mix paprika, garlic salt, thyme, black pepper, and cayenne together in a small bowl until well combined.

Step 3

Dip each sea bass fillet into the melted butter, evenly coating both sides. Sprinkle both sides with seasoning mixture.

Step 4

Grill, covered, for 3 to 4 minutes. Flip and cook until fillets are blackened and flaky, 3 to 4 more minutes.

Step 5

Serve with lemon halves and dill sprigs.
