*The calories listed are an approximation based on the ingredients in the recipe card and a serving size of 6 ounces. Actual calories will vary.*For more information, tips, and answers to frequently asked questions, please refer to the post.*We used frozen (thawed) mahi mahi filets, but fresh filets also work. *Old Bay Seasoning is salty. It's possible that using Old Bay plus the salt could be too strong for some. Consider using less, and adding additional salt after the fish cooks if desired.
