This Grilled Mahi Mahi with Korean Dipping Sauce was one of the first grilled fish recipes on the blog. And recently I had just a few small pieces left from one of those bags of frozen Mahi Mahi you get at Costco and decided to update the photos! And I also greatly increased the marinating time for this recipe, after I decided I wanted a bit more of the sweet-soy flavor in the finished dish.
This recipe for Mahi Mahi cooked on the grill uses a soy-sesame sauce that has a touch of sweetness and a touch of spiciness. 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 a bit if you prefer.
And personally I think grilled fish is great for dinner any time of year, so don’t hesitate to make this on a stove-top grill pan when it’s not grilling season.
What ingredients do you need for this recipe?
- Mahi Mahi fillets or other firm mild fish
- soy sauce or Gluten-Free Soy Sauce (affiliate link)
- Unseasoned Rice Vinegar (affiliate link)
- sesame oil (affiliate link)
- Golden Monkfruit Sweetener (affiliate link) or low-carb sweetener of your choice
- Garlic Powder (affiliate link)

What gives this recipe 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!
How can you keep the 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.

What if you don’t have 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.

Hey Kalyn, unfortunately..the fish was gone before I could snap a pix. I’ll definitely be making it for one of the WHB, will keep you posted :))
Good sauce is SO key!
Yummy, looks good. And I am a big fan of anything that can be dipped.
Janelle, selling a house is a huge job. Look forward to seeing your entries when the dust settles.
Sandy, how fun. My brother lives in Venice, so I try to visit him as often as I can. Unfortunately, no visits planned for this summer.
Amanda and Tyler, thanks. It’s the talented Rand, not me, who makes the headers look so great.
Amy, thanks. More grilling recipes to come. (You can never have too many grilling recipes!)
Meltingwok, love the sound of your recipe too. Is that on your blog?
Katie, I’m trying it on salmon tonight and will report back. I’ve never cooked fish in a basket, but I’ve heard it works well.
Deborah, another Costco fan! I love their fish. Yesterday I wanted to get more Mahi Mahi but they didn’t have it. That’s my only complaint about Costco, the way they have certain things and then the next time you want it, they don’t have it any more. I loved their frozen tuna steaks but I can’t ever find them any more.
Karen, grill marks are a wonderful things, and if your husband notices them, then they must be looking pretty good!
I love the dipping sauce and will try it with salmon next time. I love mahi mahi but I’m afraid it’s no an option here.
As to the grill marks…we use a fish basket….(cheaters)
Kalyn
I want you to know that I hold you ENTIRELY responsible for my new obsession with grill marks. Before your blog, I never gave grill marks a second thought. I just threw stuff on the grill and cooked. But no more of that for me…oh no, I’ve got to be focusing on the grill marks now. I grilled some chicken on Saturday and my husband (who is unaware of my grill-mark obsession in that usual oblivious way of men!) even commented on the grill marks!!!
This looks like a great recipe! I have Costco’s mahi-mahi in my freezer and I am going to give your Asian-inspired twist a try!
Kalyn, this sauce sounds perfect for mahi mahi. I usually pan-seared them and do a light miso soy sesame sauce with basil leaves, will have to try this sometime, thanks 🙂
Mmm so many delicious grilling recipes I don’t even know where to begin! The grill marks do look fantastic. 🙂
kalyn, both tyler and i absolutely love your new masthead! it’s just gorgeous.
Kalyn,
Thanks for the info about garlic puree.
I wanted to comment also that I happened to be checking out some of your previous recipes and came across two of your restaurant recommendations for Indian and Mediterranean restaurants located on Venice Blvd. in West Los Angeles. I live about 5 blocks east of the Indian restaurant and a half a block north of Venice Blvd.
I’ve tried both restaurants, although not recently (food budget is tight). The Indian Restaurant is in a little mall with a Thai Restaurant called East Wind that I love. Their lunch prices are fairly reasonable and I have a couple of favorit dishes.
It’s fun to know you were in my neck of the woods, even if just briefly for vacation.
I’ll think about trying them again soon.
Lydia, I’ve been practicing grill marks for about ten years now, including all those catered dinners on the houseboat, so don’t get too envious. It is a really good recipe.
Sandy-La, I do like Christopher Ranch brand garlic puree, but honestly I don’t think they are that much different. I’ve bought the garlic at Costco which is kind of coarsely chopped and buzzed it in the food processor to make garlic puree, which works just fine.
Andrea, isn’t Mahi Mahi on the grill just great?
This looks so good. I’ve been grilling mahi-mahi for years, and I can’t wait to try this recipe.
You often tell us the brand names for spices you use — do you have a favorite brand of garlic puree or ground garlic?
I’m trying to figure out if I have it in my refrigerator. Costco sells a granulated garlic, but I don’t think that’s what you’re referring to.
I will be in heaven tomorrow night come dinner time:) I can’t wait to get together! Thanks again!
I have grill mark envy! I can never manage to turn things evenly, and my grill marks are always a mess. The recipe looks absolutely delicious, too.
Maria, I am making this for you! Hope you’ll like it. (Maria is my former neighbor, for those who might be wondering and she’s coming to dinner tomorrow.)
Katerina, isn’t it funny? But the food has to look good or I won’t post it. I shudder when I see some of my first posts, and I’m gradually re-cooking those things and taking new photos.
Sara, too funny. Your husband sounds like someone I’d like to meet. I like a man who cares about his grill marks!
Those grill marks are very impressive. My husband will be jealous when I show him your picture – he works hard at his marks.
it makes me feel better that I am not the only one. Sometimes it is easy to get caught up in the visual appeal of a dish – when really it is all about the taste! Looks good.
The grill marks look great!! I will have to try the sauce…I love Mahi Mahi! I usually do fish tacos with mahi, they are my favorite.
