There was at time when this flavorful and versatile recipe for Kalyn’s Lake Powell Fish Marinade was probably my most famous recipe, at least the recipe was certainly something that got requested often by the clients and friends I used to cook for on houseboat trips at Utah’s beautiful Lake Powell. That was back in the days when the South Beach Diet didn’t exist, and no one had ever heard of sustainable seafood either, and at the lake I’d often use the marinade on Thresher Shark.

Fast forward quite a few years, and now I love this marinade on grilled Mahi Mahi, which is the fish shown in these photos. You may never have thought of using a fish marinade when you’re cooking grilled fish, but this marinade is a great idea if you’re cooking for people who are suspicious about fish. It’s true that the flavors of the marinade make grilled fish a bit less “fishy” so if that’s something that appeals to your family, this may become your favorite way to cook fish on the grill.

And this marinade is literally good on any kind of fish you might want to cook on the grill! You do need to plan ahead for a few hours or marinating time, and don’t marinate the fish too long. And be careful not to overcook fish when you’re cooking it on the grill! I hope my recipe for fish marinade will be something that gets you to re-think your ideas about grilling fish if you’ve been skeptical in the past, because everyone loved this recipe all those times I used it at Lake Powell!

How to Make Kalyn’s Lake Powell Fish Marinade and Grilled Mahi Mahi:

(Scroll down for complete recipe with nutritional information.)

  1. I used the fish marinade on the wild-caught Mahi Mahi I get at Costco, and it’s a good fish for the grill because it’s firmer than many other types of white fish. (And back in the days when I was packing food for Lake Powell I would have been thrilled with fish that came sealed in individual packages like this does. Let the fish thaw in the refrigerator overnight (or in a pinch, thaw in cold water.)
  2. Mix )together the soy sauce, lemon juice, peanut oil, water, Liquid Smoke (affiliate link), seafood seasoning, pepper, onion powder, and garlic powder to make the marinade.
  3. Marinate fish in the refrigerator for a few hours, but not more than about 4 hours.
  4. Bad blogger! I was cooking several dishes when I made this fish and I forgot to take photos of it on the grill so I’m using the photos from Soy-Grilled Mahi Mahi with Korean Dipping Sauce to show you how to cook the fish on the grill!
  5. Let fish come to room temperature, oil the grill, and get the grill hot before you put the fish on.
  6. If you want those nice diagonal grill marks, lay fish at an angle to grill grates.
  7. Grill 2-3 minutes, then lift the edge to see if you have nice grill marks. When you do, rotate the fish so it’s going at the opposite angle on the grill. Cook a few minutes longer until you have criss-cross marks.
  8. Turn the fish over and cook it about 3-4 minutes more or until it feels firm, but not hard when you press on it with your finger. 
  9. The general rule for timing fish on the grill is to cook it about 10 minutes per inch of thickness; don’t overcook.
  10. Serve hot and enjoy!

Cook Time 10 minutes
Total Time 35 minutes

Kalyn's Lake Powell Fish Marinade was pretty famous with my Lake Powell friends and it's perfect for Grilled Mahi Mahi!

Ingredients

Ingredients

  • 4 pieces of Mahi Mahi, thawed if frozen (see notes)

Marinade Ingredients

  • 2 T soy sauce (see notes)
  • 2 T fresh lemon juice
  • 2 T cup peanut oil or other oil of your choice
  • 2 T cup water
  • 1/4 tsp. Liquid Smoke (measure carefully and don’t use more, see notes)
  • 1/2 tsp. Johnny’s Seafood Seasoning (see notes)
  • 1/2 tsp. coarse ground black pepper
  • 1/2 T onion powder
  • 1/2 T garlic puree powder

Instructions

  1. If using frozen fish, thaw overnight in the refrigerator or in cold water.
  2. Place thawed fish filets in a single layer in large Ziploc bag or plastic container with a snap-tight lid.
  3. Stir together the soy sauce or Gluten-Free Soy Sauce (affiliate link), lemon juice, peanut oil, water, Liquid Smoke, seafood seasoning, pepper, onion powder, and garlic powder to make the marinade.
  4. Pour the marinade over the fish and marinate in the refrigerator for at least 2-3 hours. (I wouldn’t marinate this longer than 4 hours at the most.)
  5. When you’re ready to cook the fish, remove it from the refrigerator and let it come to room temperature.
  6. Oil the grill grates thoroughly with non-stick grill spray or a paper towel dipped in oil.
  7. When fish is nearly room temperature, preheat the grill to high, or medium-high for charcoal grill. (You can only hold your hand there for 1-2 seconds at that heat.)
  8. To get nice grill marks, lay the fish top-side down at an angle to the grill grates.
  9. As soon as you put the fish on, turn the grill down to medium-high if you can. (For a charcoal grill, I would just preheat to medium-high.)
  10.  Cook fish about 2-3 minutes, or until the first grill marks appear. (I usually lift up a piece and check.)
  11.  Then rotate fish going at the opposite angle to make the criss-cross marks and cook about 2-3 more minutes.
  12.  When you have nice grill marks, turn the fish carefully and cook 4-5 minutes on the other side.
  13.  Total cooking time for fish is about 10 minutes per inch of thickness and fish should feel firm but not hard to the touch when it’s done.
  14.  Remove from the grill and serve hot.

Notes

This fish marinade is good on just about every kind of fish you could cook on the grill! Be sure to use Gluten-Free Soy Sauce (affiliate link) if needed. The Liquid Smoke (affiliate link) used in this recipe is VERY potent, so don’t be tempted to increase the amount. If you use too much it will ruin whatever you are putting it in, but in small amounts, it adds a nice smoky flavor for barbecue sauce or grilled meats. If you don't find Johnny's Seafood Seasoning (affiliate link) I'd use some kind of all-purpose seasoning that contains celery seed. Beau Monde Seasoning (affiliate link) would work if you have that.

Nutritional information is for Mahi Mahi that's marinated in the marinade and then grilled. It is based on the amount of marinade that sticks to the fish, since most of the marinade is discarded.

  1. Ginger, thanks so much. It was definitely always a hit when I used it at Lake Powell!

  2. I live in the Caribbean and have tried hundreds of marinades, most to horrible ends. THIS IS THE BEST THING I HAVE EVER TASTED. Seriously. I use it weekly. I could drink it! This weekend I had a dinner party and marinated chicken in it and baked it covered in the oven, finishing it on the grill for extra flavor. I served some of the unused marinade as a "sauce" on the side and everyone wanted the recipe. This is just a stunning marinade….and sauce. Using it tonight on some dolphin. THANK YOU.

  3. Canola or grapeseed oil would both be fine.

  4. Kalyn, do you think there would be much of a difference if I subbed in canola oil for peanut oil? My daughter has a nut allergy. If not canola, what other oil would you recommend?

  5. Kelly, Lake Powell is one of the most beautiful places on earth! It may even be better than San Diego.

  6. I know people who want fish less fishy so they'd love this 🙂 So would I. Now I need to look up Lake Powell…

  7. Crystine, glad to help.

  8. Thanks for the salad recipe!

  9. Paula, I thought I was the only one who used Liquid Smoke! So good in small doses. I've been very happy with the Mahi Mahi from Costco.
