Ingredients

FOR THE BAKED SWORDFISH

1½ pounds swordfish about 1" thick
1 lemon zested
3 cloves garlic minced
¾ teaspoon kosher salt
½ teaspoon black pepper
3 tablespoons olive oil

FOR THE TOMATO OLIVE RELISH

1 medium ripe tomato or 2-3 plum tomatoes
⅓ cup kalamata olives seeded and chopped or quartered
2 tablespoons olive oil
1½ tablespoons lemon juice
¼ teaspoon kosher salt
pinch red pepper flakes optional
6-7 fresh basil leaves thinly sliced

Instructions

Arrange the oven rack in the center of the oven. Preheat the oven to 400° F.
In a small bowl combine the zest of 1 lemon, 3 cloves garlic, minced, ¾ teaspoon kosher salt, ½ teaspoon black pepper, and 3 tablespoons olive oil. Mix well and set aside.
If you have a whole slice of fish that includes the bloodline, cut around and remove the bloodline (the dark brown or reddish center of the fish) and discard. Transfer the fish to a baking sheet and pour the lemon garlic marinade over the fish to coat it on all sides. Set aside to marinate for 15 minutes.

ASSEMBLE THE TOMATO OLIVE RELISH

Slice 1 medium ripe tomato in half and remove the seeds. Cut the tomato into ¼" dice and transfer to a small bowl. Add⅓ cup kalamata olives, 2 tablespoons olive oil, 1½ tablespoons lemon juice, ¼ teaspoon kosher salt, pinch red pepper flakes and 6-7 fresh basil leaves, chopped. Stir to combine and set aside for the flavors to marry.
Place the fish in the oven and bake for 15 minutes or until cooked through. Transfer the fish to a serving platter and scrape any remaining pan sauce over the top of the swordfish. Spoon the relish over the baked swordfish and serve.
