For this week’s Friday Favorites pick, I’m reminding you about this Grilled Mahi Mahi that’s marinated with Korean flavors and then served with Korean dipping sauce. This was one of the first grilled fish recipes I ever posted on the blog, and for quite a few years now the frozen Mahi Mahi I get at Costco has been one of my favorite choices for cooking fish on the grill. 

This Mahi Mahi cooked on the grill features a soy-sesame sauce that has a touch of sweetness and a touch of spiciness from Korean red pepper. Half the mixture is used to marinate the fish, and the other half is served as a sauce at the table. I made it just slightly spicy, but turn up the heat by adding a bit more of the Korean Red Pepper Powder (affiliate link) if you prefer.

There’s also a recipe on the blog for Korean Salmon that uses this same delicious marinade/sauce mixture. And personally I think grilled fish is great for dinner any time of year, so don’t hesitate to make this on a Stovetop Grill Pan (affiliate link) when it’s not grilling season or if you don’t have an outdoor grill!

Why is Mahi Mahi a good fish to cook on the grill?

Mahi Mahi is a relatively firm fish, which makes it easy to cook on the grill compared to softer and more flaky types of fish. And the mild flavor goes with a variety of sauces and toppings.

What gives this Grilled Mahi Mahi the Korean flavors?

I’m definitely not claiming this is an authentic Korean recipe! I’m using the word Korean in the recipe title as a tip for you to use Korean Red Pepper Powder (affiliate link) in the dipping sauce, which will give it amazing flavor with a nice spicy kick! Of course if you don’t have any of that another type of spicy red pepper powder will also work.

How low in carbs is the Grilled Mahi Mahi recipe?

This amazing grilled fish recipe only has 4 net carbs per serving!

How can you keep Grilled Mahi Mahi from sticking to the grill?

Fish can be tricky to cook on the grill, but I love a non-stick spray called Pam for Grilling, (affiliate link) which really helps prevent food from sticking. You can also oil your grill with a paper towel dipped in olive oil with good results.

Can you make Grilled Mahi without an outdoor grill?

If you don’t have an outdoor grill or it’s not grilling season the Mahi Mahi can cook perfectly on a Stovetop Grill Pan (affiliate link) or a George Foreman Grill (affiliate link). Remember the George Foreman is cooking both sides of the fish at the same time, so the cooking time will be much shorter.
