Mouthwateringly tender and with so much flavor, rosemary garlic roast beef is the ideal dish to serve for special occasions. It looks beautiful as it tastes. Gorgeously seasoned with a garlic herb rub, this roast tenderloin recipe is simple to make but tastes like a dish straight out of the kitchens of a 5-star restaurant, but with very little effort needed on your part.
– Trim away any excess fat and connective tissue from the tenderloin.
– One optional step you may want to try is to brown the tenderloin before you pop it in the oven. This seals in the juices as it's roasting, giving you a more succulent roast, and adds flavor thanks to the browning of the meat.
Preheat your oven to 275°F. Line a baking tray with foil and lightly spray it with cooking spray. Pat the beef tenderloin dry with a paper towel. Season it with extra virgin olive oil, salt, and pepper. Mix garlic, rosemary, and thyme in a small bowl, then rub the garlic mixture into the beef.
Put the beef onto the baking tray. Roast in the oven for about 50 minutes to 1 hour and 15 minutes, depending on your preferred doneness.
Cover with foil, then let the tenderloin rest for about 10 minutes before cutting and serving.
In a small bowl, whisk together the sour cream, mayonnaise, horseradish, chives, salt, and pepper. Cover and refrigerate until ready to serve.
– For medium-rare, the internal temperature should read 130 to 135°F. For medium, look for a reading of 150°F. Begin checking the temperature with a meat thermometer after 50 minutes.
– Be sure to place your thermometer in the thickest part of the roast for the most accurate reading.
