6 (7- to 8-ounce) beef tenderloin steaks (each about 1 1/2 inches thick)
Coarse kosher salt
Cracked black pepper
3 tablespoons canola oil
6 tablespoons (3/4 stick) chilled unsalted butter, divided
4 garlic cloves, peeled, smashed
2 fresh thyme sprigs
2 fresh rosemary sprigs
1 cup finely chopped shallots
1/2 cup Cognac or brandy
2 tablespoons tawny Port
3 cups low-salt chicken broth
2 tablespoons Dijon mustard

Steps:

Preheat oven to 250°F. Sprinkle steaks on all sides with salt and pepper. Heat oil in heavy large skillet over high heat. Add steaks and sear until brown, about 2 minutes per side. Reduce heat to medium-low. Add 3 tablespoons butter, garlic, thyme, and rosemary to skillet. Cook steaks to desired doneness, turning occasionally and basting with pan juices, about 12 minutes for medium-rare.
Transfer steaks to small rimmed baking sheet and keep warm in oven.
Pour contents of skillet into small bowl. Return 3 tablespoons drippings from bowl to same skillet and place over high heat. Add shallots and sauté 2 minutes. Add Cognac and Port and stir 1 minute, scraping up any browned bits. Add broth and boil until sauce is reduced to 1 cup, about 12 minutes. Whisk in Dijon mustard, then remaining 3 tablespoons cold butter, 1 tablespoon at a time. Season sauce to taste with salt and pepper. Set aside.
Arrange steaks on plates; whisk any accumulated juices from baking sheet into sauce. Spoon sauce over steaks and serve.
