Ingredients
To Make the Garlic-Herb Butter
- 8 ounces butter softened
- 3 garlic cloves minced or grated
- 1 tablespoons finely chopped fresh thyme
- 1 tablespoons finely chopped fresh rosemary
For the Steaks:
- 2 tenderloin steaks 8 oz each and 1 to 1 1/4-inch thick
- 1 tablespoon olive oil
- Salt and freshly ground black pepper
- Fresh herbs or microgreens for garnishment
Instructions
For the Garlic-Herb Compound Butter:
- In a small dish, add the butter, garlic, thyme, and rosemary. Use a spatula to combine all of the ingredients well. Transfer the mixture onto a small piece of parchment paper. Roll into a log and twist the ends shut. Place in the refrigerator for 2 hours, or until the butter is firm.
For the Tenderloin Steaks:
- Remove the steaks from the refrigerator and place them on the kitchen countertop for 30 minutes prior to cooking.
- Preheat the oven to 450°F
- Place a cast-iron griddle or heavy-bottomed, oven-proof skillet on the stove-top over medium-high heat and allow it to preheat for about 5 minutes. Season both sides of the steaks generously with salt and pepper. Add the oil to the griddle and tilt the pan to distribute it a little. Place the steaks on the oily pan and do not move them for 3 minutes, let them sear to get a good crust. Flip the steaks and sear the other side for 1 minute.
- Transfer the pan to the preheated oven and cook for 5 minutes or until the temperature reaches your desired doneness with an instant-read thermometer (see notes for temperatures). Transfer the pan from the oven and place the steaks on a platter, cover with foil and allow to rest for 2-3 minutes.
- While the steaks are in the oven: Remove and unwrap the chilled log of garlic-herb butter from the refrigerator, cut two thin slices, reserve until steaks have rested.
To serve:
- Add a mound of hot mashed potatoes to each serving plate, place a tenderloin steak on each mound with a slice of the garlic-herb butter on top of the steak, garnish with fresh herbs or microgreens. Add accompanying vegetables to the plate and serve immediately.
