Preparation Instructions:
Preheat oven to 400 degrees. Place whole potatoes on a sheet pan and roast for 35-40 minutes or until the potato skins begin to burst.
Rub 1.5 tablespoons of Garlic Butter Pepper Herb Rub with 2 tablespoons of olive oil over the swordfish steaks. Set aside and heat a grill or grill pan on high and spray with cooking spray. Grill swordfish steaks 5 minutes on one side, flip, and grill for another 3-4 minutes. Set aside to rest.
In a mason jar, combine 1/2 tablespoon Garlic Butter Pepper Herb Rub, garlic, Dijon mustard, Champagne vinegar, 1/2 cup of olive oil, and kosher salt. Shake vigorously until well combined.
When potatoes are finished roasting, place in a large bowl and mash with a potato masher. Drizzle the herbed vinaigrette over all the potatoes and combine well. Fold in chopped scallions and serve at room temperature.

Frequently Asked Questions
How long should I grill the swordfish and how do I know it is done?
Grill on high heat so the steaks cook fast. Start about 5 minutes on the first side, then flip and grill 3 to 4 minutes more. The fish is done when it is opaque through the center and flakes slightly. For food safety, check that the internal temperature reaches 145 F.
What if I do not have a grill or grill pan?
You can broil the steaks 4 to 6 inches from the heat for similar timing, or pan-sear them in a hot skillet with a little oil for about 3 to 4 minutes per side. Finish in the oven only if the steaks are thick.
Can I use another fish instead of swordfish?
Yes. Choose a firm, meaty fish so it holds up to grilling. Good swaps are tuna, mahi-mahi, halibut, or thick salmon steaks. Adjust cook time for thickness.
What can I use if I do not have Garlic Butter Pepper Herb Rub?
Make a quick substitute by mixing softened butter or olive oil with minced garlic, cracked black pepper, chopped parsley and a pinch of salt. Use about 1 to 2 teaspoons garlic per tablespoon of fat and season to taste.
How do I make and use the champagne vinaigrette?
Shake together 1/2 tablespoon herb rub, 1 garlic clove, 1 teaspoon Dijon, 3 tablespoons champagne vinegar, 1/2 cup olive oil, and 1/2 teaspoon kosher salt in a jar. Pour over mashed roasted potatoes and fold in scallions. Save any extra for a green salad.
Can I make this dish ahead of time?
Yes. Roast the potatoes and make the vinaigrette a day ahead. Keep the potatoes and dressing separate until just before serving so the salad does not get soggy. Cook the swordfish the day you plan to serve for best texture.
How should I store and reheat leftovers?
Store cooked fish and potato salad in airtight containers in the fridge for up to 3 to 4 days. Reheat fish gently in a low oven (275 to 300 F) until warmed through, or enjoy it chilled. Rewarm potatoes in the oven or microwave; if the dressing separates, shake and toss before serving.
What sides and drinks pair well with this meal?
Serve a crisp green salad, grilled vegetables, or steamed asparagus alongside. For drinks, a chilled Sauvignon Blanc, unoaked Chardonnay, or sparkling wine complements the champagne vinaigrette and herb rub.
