You might just swap your holiday turkey for this decadent beef tenderloin roast once you've tried it! A flavorful garlic and rosemary butter gives this tender meat so much flavor! Serve this with roasted broccoli, mashed potatoes, or a simple green salad, and let the tenderloin be the star of the show. We recommend starting your roast the day before. A sea salt and pepper rub the day before ensures the best crust around your roast.

Ingredients

3 pound beef tenderloin roast
1 teaspoon sea salt
black pepper to taste
4 tablespoons butter salted
4 cloves garlic minced
1 tablespoon rosemary chopped
1 teaspoon dijon mustard

Instructions

Tie the tenderloin roast with kitchen twine. This is done by spacing individual pieces of twine out every 2-3 inches along the roast.
Season the roast with salt and pepper. Leave it uncovered in the refrigerator overnight.
Preheat the Sharp SuperSteam+ Built-In Wall Oven to Steam/Roast at 450º F for 15 minutes.
In a small bowl, add softened butter, rosemary, garlic, and dijon. Mix the ingredients together well.
Coat the roast in the butter mixture.
Roast the beef for 15 minutes, and then flip it over and select "more time" and add 10 minutes. At the end of the 10 minutes, use a meat thermometer to check the internal temperature of the roast, using the chart below for desired doneness. Continue cooking the roast for 5-10 minutes at a time until it reaches the right temperature.
Allow the meat to rest for 10 minutes before slicing it.
