A fun new way to enjoy your swordfish with a classic Caesar sauce. Tender and rich in flavor.

As you may have noticed I do love fish, but sometimes I get stuck with the same one over and over. I am opening up my repertoire a bit and adding swordfish.

Caesar Roasted Swordfish

Swordfish has never been one of my favorite fish. I always found it too dry and, therefore, always stayed away from it. Well, the following recipe made me change my mind.

However you will enjoy this recipe as the Caesar sauce gives it that great savory taste that will make you come back for more.

Recipe Notes

Make Caesar’s sauce first as you will use 2/3 of it to marinate the swordfish steaks in it.

I use my food processor over a blender. The food processor will better macerate the garlic and anchovies, for those who are inclined to like anchovies.

The swordfish steaks are nicely marinated with the sauce, making the fish tender. Out of this world, how beautiful is the fresh garlic, prepared mustard to infuse the fish.

The mayonnaise will render the fish as tender as it can be.

Cooking tips

  • Squeezing the lemon wedges over prior to enjoying it, will enhance the flavor.
  • Use real mayonnaise, not the sweet kind. Some store brand mayonnaise is too sweet.
  • The anchovies fillets bring a great flavor to it, hence do use it. Hide them if you must from the finicky eater. Of course, you can add more.
  • Always buy anchovies fillets that are in a glass jar. Easy to open and close and you can use how many as you need and not have to toss the rest.
  • Drain the capers well. If stored under salt a must as they will be too salty.
  • Sauteed capers are just delicious. The flavor is enhanced. The technique found mostly in Mediterranean cuisine
  • When seasoning with salt and pepper, do season the thin side of the fish as well.
  • If time permitting, let your fish marinate in the sauce for up to one hour.
  • I always line my cookie sheet with aluminum foil and then place a parchment sheet over it. Easy to remove the fish, while super easy to clean your cookie sheet.

Side dishes suggestions

Due to all the mixture of flavors in the swordfish alone, simple potatoes, either parboiled and sauteed with butter and parsley, or mashed potatoes, are a great side dish as well.

Carrot salad will bring a sweet fresh balance to it as well.
