Ingredients:
- 2 (8-10 ounce) steaks (about 225-285g each), ribeye or New York strip, about 1-inch thick (2.5cm)
- 2 tablespoons (30ml) olive oil
- 1 teaspoon (5g) kosher salt
- ½ teaspoon (2.5g) freshly ground black pepper
- 1 tablespoon (15g) unsalted butter
- 1 shallot, minced
- ½ cup (120ml) dry red wine (e.g., Merlot, Cabernet Sauvignon)
- ½ cup (120ml) beef broth
- 1 tablespoon (15ml) balsamic vinegar
- 1 teaspoon (5ml) Worcestershire sauce
- 1 tablespoon (15g) cold unsalted butter, cut into small pieces
Instructions:
- Pat steaks dry with paper towels. Season generously with salt and pepper.
- Heat olive oil in the skillet over high heat until smoking hot.
- Place steaks in the hot pan, ensuring they aren't touching. Sear for 3-4 minutes per side for medium-rare, or adjust to desired doneness.
- Use a meat thermometer to check the internal temperature. (Medium-Rare: 130-135°F/54-57°C, Medium: 135-145°F/57-63°C).
- Remove steaks from the pan and let rest on a cutting board for 5-10 minutes, loosely tented with foil.
- While the steaks rest, melt 1 tablespoon butter in the same skillet over medium heat. Add the shallot and cook until softened, about 2 minutes.
- Pour in the red wine, scraping up any browned bits from the bottom of the pan.
- Bring the wine to a simmer and let it reduce by half, about 5-7 minutes.
- Stir in the beef broth, balsamic vinegar, and Worcestershire sauce. Continue to simmer until the sauce thickens slightly, about 3-5 minutes.
- Remove from heat and whisk in the cold butter pieces one at a time until melted and the sauce is glossy.
- Slice the steak against the grain and serve immediately, drizzled with the red wine reduction.
