Grilled mahi mahi is a delicious low fat, high protein, low carb entree. For this recipe, the serving size is a half pound, but you can certainly have a quarter or third pound serving, whatever your appetite supports. You can grill the mahi mahi over charcoal or gas, or roast it in the oven.

You can enjoy this simple recipe not only for mahi mahi, but also for swordfish or tilapia. It works for any fish that is not too delicate to grill. The simple marinade of Caesar or italian dressing is easy to use straight from a store-bought bottle, but you can mix up your own if you prefer.

I usually use a grilling basket when I am grilling fish, to ensure the fish doesn't fall through the grate.


  • 1 pound mahi mahi filets
  • 1 cup Caesar salad dressing or Italian salad dressing for marinade
  • Salt to taste


1. If the fish is frozen, defrost it in refrigerator ahead of time.

2. Place the fish in a plastic bag or marinator with the Caesar salad dressing. Refrigerate it for 30 to 60 minutes

3. Start the grill or coals and bring them up to temperature.

4. Cook with indirect heat. If using a charcoal grill, form some aluminum foil into a round disk 6 inches across and place just above the coals. If using a gas grill, turn off the center flame.

5. Remove the fish from marinade.

6. Place the fish on the grill. You can use a grill basket to ensure it doesn't fall through the grate. Grill for approximately 5 to 8 minutes per side. When you turn the fish, brush it with more of the Caesar dressing. Cook the fish until it is cooked through - do not overcook. Fish is done when all of the flesh is opaque to white and the flesh can be easily separated with a fork.

7. Serve with grilled vegetables prepared at same time on the grill. Skewers of red and green peppers, tomatoes, onions, zucchini, etc. are colorful and nutritious side dishes with the mahi mahi.

Food Safety Tips for Fish

Fish should be kept refrigerated until immediately before cooking.

When you are marinating the fish, it should be kept in the refrigerator. Do not use the marinade for any other purposes once it has been in contact with the fish. Discard it after marinading and brushing on the fish while it is grillling.

If you are going to cut the fish before you grill it, use a clean cutting board and knife and clean them with hot, soapy water before you use them for any other food.

Store any leftover portions of grilled fish in the refrigerator and enjoy them within a couple of days.
