Tips & Variations
- For a dairy-free option, replace butter with olive oil without sacrificing flavor.
- If you don’t have Old Bay seasoning, a mixture of paprika and salt works well as a substitute.
- Try fresh minced garlic instead of garlic salt for a more pronounced garlic flavor.
- Swap mango salsa for pineapple salsa or chimichurri to change the flavor profile while keeping it fresh.
- Choose thick filets to maintain moisture and prevent the fish from drying out on the grill.
