Step-By-Step Photos and Directions:

Washed and cut potatoes in a bowl.

Step 1: Wash mini potatoes and slice them in half. Microwave them for 5-7 minutes in a microwave-safe bowl. (Microwave them for 7 minutes if they are on the large side.) This will soften them enough to grill.

Step 2: Preheat your grill to 400º F.

Step 4: Fold up the foil to close the packets. Leave a small section open so the steam can vent out.

Frequently Asked Questions:

How long do you grill mahi mahi?

The exact time to grill mahi mahi depends on how thick your cut of mahi mahi is. The filets by Open Nature are not thick, and mine grilled in just 10 minutes.

Can you use lemon instead of lime?

You can use either lemon or lime in this recipe.

How do you know when mahi mahi is done?

Insert a fork into the mahi mahi; if the fish flakes easily, the fish is done cooking. It will also feel firm to the touch.

How long will mahi mahi keep fresh?

This fish will keep fresh for up to 4 days in a refrigerator. Make sure to keep the cooked fish in a sealed, airtight container.

      Great! Added fresh green beans, slices of orange and yellow bell peppers and put two slices of lemon on top; along with the asparagus and potatoes. It is the easiest and most delicious way to fix my favorite fish; Mahi Mahi… Wife loves it! Thanks.

    This was a delicious and easy recipe. I did not have the spices suggested so used what I had – Pride of Szeged fish rub. Nor did I have a fresh lime so just used a splash of bottled lime juice. Otherwise, followed the recipe as listed and it was so good. The fish was done perfectly at 10 minutes. Bonus – no cleanup!

  2. This is a great technique – thanks for showing us how it’s done. So easy to change up the fish/veggies/spices for a new flavor with the same process. Great idea! Love this recipe.
