Keto Butter-Basted Beef Tenderloin
A special occasion calls for a special dinner, and this simply divine beef recipe is the perfect centerpiece for any celebration. The method is foolproof, resulting in a perfectly pink inside and a gorgeous seared crust. Once sliced, beef tenderloin becomes the extremely expensive “filet mignon” cut served in fancy restaurants. Serve it with its butter basting liquid or top it with a stunning and equally simple homemade blender Béarnaise (the recipe follows; don’t forget to add the macros if you include it); the classic pairing is a holiday-dinner showstopper. Note: this recipe requires you salt and refrigerate the beef at least 4 hours before cooking; it also requires the beef is tied, which a butcher can do for you or you can do for yourself with butcher’s twine. (Find easy videos on how to tie online!)
Servings: 8 One Serving: 1/8 of a 8 serving recipe
Ingredients
- 3 lb beef tenderloin, tied with butcher twine
- 4 tsp sea salt
- 1/4 tsp freshly ground pepper
- 2 Tbsp olive oil
- 8 Tbsp (4 oz or 1 stick) unsalted butter
- 1 tsp garlic powder
- 1 sprig fresh thyme
- 1 sprig fresh rosemary
Instructions
- Rub the tenderloin with three-quarters of the salt, wrap it tightly in plastic, and refrigerate for at least 4 hours and up to 2 days.
- Preheat the oven to 225°F (105°C). Line a rimmed baking sheet with aluminum foil, turning up the foil’s edges.
- Remove the tenderloin from the refrigerator, pat it dry with paper towels, then place it on the foil-lined pan. Rub the meat with the oil, season with the remaining salt and the pepper, then cook until a meat thermometer inserted into the center reads 120°F to 125°F, 1-1/2 to 2-1/2 hours, depending on your oven and the meat’s temperature after coming out of the refrigerator.
- Meanwhile, in a small sauté pan, combine the butter, garlic powder, thyme, and rosemary. Heat over medium heat until the butter melts and begins to bubble. Keep warm. Place an oven rack 6 inches from the broiler. Preheat the broiler.
- Pour the melted-butter mixture over the roast. Return roast to the oven and broil about 4 inches from the heat source for 2 minutes to quickly develop a crust.
- Remove the roast from the oven, let it rest for 15 minutes, slice, drizzle with butter sauce/pan drippings, sprinkle with salt, and serve.
