Got a nice cut of Swordfish, any seasoning suggestions?

When in doubt and when you don't want to mess up a nice meat, keep the seasoning as simple as possible you can always add seasoning but you can't take it away. Simplest thing is just a dusting of salt and pepper to taste with oil depending on how you are cooking it. Never done swordfish but apparently rosemary goes well with it, especially if it's fresh.

Lemon goes well with most seafood but you can leave it out and just squeeze a drop on an individual bite after serving instead marinating the whole thing

Easiest rule of thumb when figuring out spices if you dont know what youre doing: what place is the food from? Those traditional spices will be fine unless the ingredient is particularly rare. Japan and spain for swordfish - spanish and japanese spice mixes will be fine.

Recipes use lemon and lime for fish because they want an acid. Go to japan, somewhere citrus is more rare, and what do they use? Vinegar. Ergo, any acid can probably be swapped in and you can build other seasonings around it

I like horseradish with fish but I've never had swordfish. Dill is good. I think bongs use white vinegar on fish instead of lime. Acid gets rid of really fishy flavor part of fish

Barbecue seasonings, butter, and add sauce at the last minute. Or teriyaki.

I don't think I've ever eaten swordfish tbh. I see it on menus and have heard it's good, but never tried it. That being said, citrus is my fave thing on fish. Maybe some sort of asian type sauce?
