- 1 1/2 pounds boiling potatoes, cut into 1/2-inch pieces
- 1/2 cup olive oil
- 5 cloves garlic, chopped
- 1/2 teaspoon salt
- 1/2 teaspoon fresh-ground black pepper
- 4 (8 ounce) swordfish steaks, about 1 inch thick
- 1 teaspoon chopped fresh rosemary
- 1 cup mayonnaise
- 2 tablespoons chopped fresh parsley
- 2 tablespoons drained chopped capers
- 1 teaspoon wine vinegar
- Heat the oven to 400 degrees F. In a large roasting pan, toss the potatoes with 1/4 cup of the oil, half the garlic, and 1/4 teaspoon each salt and pepper. Put in the oven for 15 minutes; stir once.
- Meanwhile, coat the swordfish with the remaining 1/4 cup oil, garlic, 1/4 teaspoon each salt and pepper, and the rosemary. Put the fish on a baking sheet and put it in the oven along with the potatoes. Cook, stirring the potatoes once, until the fish and potatoes are both done, 10 to 12 minutes for 1-inch-thick steaks.
- In a small bowl, combine the mayonnaise with the parsley, capers, and vinegar. Serve the roasted swordfish and potatoes with the caper mayonnaise.
