Heat oil in a large heavy-bottom ovenproof skillet.
Sprinkle tenderloin with salt and pepper, and cook on all sides 5 minutes or until well-browned.

Sprinkle tenderloin with garlic, rosemary, and 1 tablespoon thyme, pressing to adhere. Return tenderloin to skillet, and bake at 400 for 20 minutes (to 145 for medium rare) or to desired degree of doneness.
Remove from skillet; let stand 10 minutes before slicing.
Add broth and wine to skillet, and place over medium-high heat; bring to a boil, and cook 7 minutes or until reduced to 1/2 cup. Reduce heat to low; whisk in butter one piece at a time. Stir in 1/2 teaspoon thyme.
