Hi, August. Where the heck did you come from? August is such a tough one for me. Because on the one hand, I’m pretty much obsessed with the weather that usually comes with the month. Super hot and sunny and summer-y. On the other hand, it’s signaling the end of the summer, which has me feeling super ugh.

I know that summer technically doesn’t end until the middle of September, but let’s fact it, once September hits, fall is here. I saw on Facebook that some people’s kids are actually going back to school today. On August 1. What? In my day and in my New England region, we never went back to school until after Labor Day in September. Also, today’s weather is rainy and chilly and I walked past a girl wearing suede booties this morning. Too soon.

Let’s keep the grill running throughout the month of August. And the summer cocktails coming. Or you could just grill your cocktails… On fish. OK, that sounds weird, but I promise you that this grilled Mojito Swordfish is anything but weird.

It’s quick and simple to prepare, which  means you can come in from the beach, throw the fish in the 20-minute marinade, heat up the grill, and have dinner on the table in no time.


The grilled swordfish marinade basically contains a classic mojito cocktail- rum, lime juice, and mint. Plus an abundance of garlic… Which you probably wouldn’t want in your mojito cocktail, but which goes perfectly with this fish.

You’ll want to let it sit in the marinade for about 20 minutes for best results.

And then it’s ready to be cooked. It’s done after about six minutes on the grill and a little extra sprinkling of mint on top. Ooh la la. Almost as good as a tropical island vacation, right?? My suburban New England backyard… tropical vacation… What’s the difference really?

There’s something about swordfish that is just begging you to keep it simple and stay away from any frills. I think this dish is the perfect balance for keeping things exciting, but not taking away from the integrity of the fish (you know… gotta keep the fish’s integrity in mind at all times!). The flavors were light and fresh and summer-focused, but the full swordfish flavor still came through.

The only thing I did wrong with this meal is to not also serve it with actual mojito cocktails. I feel like that was a pretty big faux pas on my part. But don’t worry, I dined on my grilled swordfish with a White Claw hard seltzer, which is pretty much my (and everybody else’s) new favorite drink of the summer.

I probably say this every time I make any type of seafood, but I never really understand why people are so afraid of it. Since fish is usually best served simple, it doesn’t really require a lot of frills and can be served quickly and easily. Plus, when you grill it, you can keep any “fishy” smells outdoors, if that’s what you’re afraid of!

I hope that August brings with it a million more grilling days. Or at least 31. I’m going to spend my time focused on how much more of summer we have to enjoy (and eating more grilled mojito swordfish) rather than the fact that it’s beginning to fade.

    Love your flavour combination for the swordfish. I had a piece out of the freezer last week and my puppy decided to eat it! Not a good result for anyone. Enjoy the last 6 weeks of summer 🙂

    I don’t have to go back to school so I am boycotting and I am not going to stop celebrating summer until I absolutely have to – September 22nd. Well, let’s be real.. I’m going to still celebrate summer until all the produce is gone at the market.. so hopefully it will be more like October. hahahaha. Anyways, I love me some swordfish and this looks fab, Sues! Grill mark perfection and that mojo?! YES!!! Gimme gimme!! Cheers, girlie!

    Nice recipe here! You remind me of some experiments I did in the beginning of my cooking career making mojito chicken. One of my better experiments and I lately tried it again with pork jowls for my blog! But never thought about doing it with fish! Great idea! Need to try it! I totally need to do more fish at all!
