FAQs
Can I use frozen mahi mahi?
Yes, just be sure to fully thaw the fillets in the refrigerator before grilling for the best texture and even cooking.
How do I keep mahi mahi from sticking to the grill?
Lightly oil both the fish and the grill grates before cooking, and avoid flipping too early. Let the fish release naturally when it’s ready.
What temperature should mahi mahi be when fully cooked?
Mahi mahi is fully cooked when it reaches an internal temperature of 137°F and flakes easily with a fork.
Can I use a grill pan or indoor grill?
Yes, a grill pan or indoor electric grill works well for this recipe if you don’t have access to an outdoor grill.
Is mahi mahi healthy?
Yes, mahi mahi is low in fat, high in protein, and a good source of B vitamins and selenium, making it a healthy choice for most diets.
What should I serve with grilled mahi mahi?
It pairs well with rice, grilled vegetables, tropical salsas, fresh salads, or roasted potatoes.
How thick should mahi mahi fillets be?
Aim for fillets that are about ¾ to 1 inch thick for even grilling and moisture retention.
Can I marinate the fish ahead of time?
