Rib-Eye Steaks with Thyme-Shallot Butter

Heat oven to 425°F. Coat 11"x17"x1" nonstick sheet pan with cooking spray. In small bowl, use fork to mash butter with shallots, thyme, zest, and 1/4 tsp. salt. Transfer to center of small sheet of plastic wrap; roll into 1"-diameter log; twist ends closed and chill in freezer to harden until ready to use.

In bowl, combine 1 tbsp oil with potatoes. Toss with paprika, 1/4 tsp salt, and 1/8 tsp pepper. Arrange potatoes in single layer around edges of sheet pan. Roast 20 min., rotating pan front-to-back after 10 min.

Meanwhile, combine asparagus with remaining oil; toss with 1/4 tsp salt and 1/8 tsp pepper. After potatoes have roasted 20 min., add asparagus to center of sheet pan. Roast 10 min., or until vegetables are tender. Transfer potatoes and asparagus to platter; tent with foil to keep warm.

Position oven rack 4"-5" below heat source; preheat broiler. Season steaks with remaining salt and pepper; place on sheet pan. Broil, turning once, 6–8 min., until instant-read thermometer inserted horizontally into thickest part of steak registers 130°F for medium-rare. Serve steaks topped with a slice of butter.
