Step 1

In small bowl, mix softened butter, garlic, thyme, salt and pepper. Set aside.

Step 2

Spray 6-quart slow cooker insert with cooking spray. Pour beef-flavored broth into slow cooker. Rub beef roast all over with vegetable oil. Heat 12-inch skillet over medium-high heat. Cook 4 minutes on ribs side, then turn and cook 1 to 3 minutes each on other sides, until browned, holding roast upright in skillet with tongs if necessary.

Transfer to slow cooker, ribs side down. Rub butter mixture on top and sides of roast. Cover and cook on Low heat setting 3 to 5 hours or until desired temperature in center. For medium-rare, cook 3 hours 30 minutes to 4 hours, or until meat thermometer inserted in center reads 135°F. For medium, cook 4 hours 30 minutes to 5 hours, or until meat thermometer inserted in center reads 145°F. Transfer roast to cutting board. Cover roast loosely with foil; let stand 30 minutes before carving. Cut into slices.
