Step 1. Heat the oven to 425°F (220°C). Toss Potato with half the Olive Oil and some of the Salt on a sheet pan. Spread in one layer and roast until browned and tender, about 25 minutes, turning halfway.
-
Step 2. Meanwhile, mix Butter, Garlic, Fresh Parsley, Dijon Mustard, Red Pepper Flakes, and a squeeze of juice from half the Lemon in a small bowl.
-
Step 3. Season Beef Sirloin on both sides with the rest of the Salt and the Black Pepper.
Cook
-
Step 4. Heat the rest of the Olive Oil in a large skillet over medium-high heat. Sear the steaks until browned and an instant-read thermometer reaches your preferred doneness, about 4 minutes per side for medium-rare.
Finish & serve
-
Step 5. Transfer the steaks to a cutting board and rest for 5 minutes so the juices settle.
-
Step 6. Meanwhile, toss Arugula and Cherry Tomatoes with juice from the rest of the Lemon.
-
Step 7. Slice the steaks against the grain and fan them onto plates. Spoon the cowboy butter over the warm steak and serve with the potatoes and salad.

Good to know
For medium-rare steak, remove it from the skillet at about 130°F; its temperature will rise as it rests.
Swap it
Use baby spinach in place of arugula for a milder salad.
