Mmmmm, swordfish steak. I believe I first tried it about 5 years ago and have enjoyed it ever since. It’s one of my seafood favorites that’s quite steak-y because of how thick they are, but cooks super quick and isn’t “fishy” tasting. When cooked just right (as in, not overcooked and dry), it’s so delicious and tender, but mild enough that it goes well with any sauce or spices. I absolutely love it.

This is a great weeknight recipe because you’ll have a healthy and flavorful dinner in about 20 minutes. You don’t even need to turn on the oven!
The best part about it is the creamy lemon basil sauce, because it really brightens up the flavors. I’ve marinated swordfish steak before in all different sauces, but I like to keep it simple with the fish itself then give it a boost after cooking with a sauce or dressing. Swordfish itself is pretty neutral in flavor so this works out really well.
If you are unfamiliar with swordfish, don’t be intimidated. It’s one of the easiest fish to cook, because it cooks so fast compared to its thickness, and it’s quite nutrient dense! It’s one of the few food sources of vitamin D and has a substantial amount of anti-inflammatory Omega 3 fatty acids. Love when delicious food is jam packed with nutrients!

SUPER excited to make this! Anyway to substitute the avocado for something else??
You can just make it without it!
I used your recipe but cooked it in my sous vide. It came out amazing! I wish I could post a picture!
Sounds amazing and so glad you liked it. I need to get a sous vide cooker. I hear so many great things!
I had a couple of beautiful Aussie barramundi fillets, and some day old basil, and was trying to figure out how to combine the two when I came across this recipe. It worked really well, and we loved it. Healthy, too. My Japanese wife thought it might be fun to see if it worked with shiso leaves instead of basil, so we’re going to try that at some time.
Love your variation! So glad you enjoyed it. Let me know how it works with shiso leaves!
Just tried making the recipe with shiso instead of basil. Works really well. It was hard to decide which version we preferred. We currently have more shiso growing in the garden than we know what to do with, so it’s a great way to use it. Thanks for a great recipe
Wow, Impressive.
