How to Make It
Preheat oven to 400°.
Combine 2 teaspoons oil, 2 teaspoons thyme, 1/4 teaspoon salt, 1/4 teaspoon pepper, and potatoes in a bowl. Spread potato mixture in an even layer on a baking sheet; bake at 400° for 30 minutes or until browned, stirring every 10 minutes.
Heat a medium ovenproof skillet over medium heat. Add remaining 1 tablespoon oil; swirl. Sprinkle steak with remaining 1/4 teaspoon salt and remaining 1/4 teaspoon pepper. Add steak to pan; cook 10 minutes, turning to brown all sides. Place pan in oven; bake at 400° for 12 minutes for medium-rare or until desired degree of doneness. Place steak on a cutting board; let stand 5 minutes.
Wipe out pan with paper towels. Heat pan over medium-high heat. Add remaining 2 teaspoons thyme and shallots to pan; sauté 30 seconds. Add wine; cook until liquid almost evaporates, scraping pan to loosen browned bits. Add stock; cook 4 minutes or until liquid is reduced to 1/3 cup. Remove pan from heat; stir in butter. Cut steak across the grain into thin slices. Divide steak between 2 plates; drizzle with red wine sauce. Serve with potatoes.
