    Want juicy roasts? Let them sit before and after cooking.

    Thick cuts of beef and pork, like roasts, should always be left out at room temperature for a period of time before cooking for even cooking and juicier meats. Depending on the thickness, 20-30 minutes is sufficient and of course be sure to check for doneness with an instant-read thermometer.

    And then after cooking, allow the roast to rest outside of the oven for another 15 minutes to allow the meat to relax and the juices to be reabsorbed.

    Ingredients
     

    • 3 pounds beef tenderloin roast
    • 3 tablespoons olive oil (divided use)
    • 1 pound white mushrooms (sliced)
    • 2 large shallots (sliced)
    • 3 tablespoons fresh rosemary leaves (finely chopped)
    • 3-4 cloves garlic (minced)
    • sea salt and black pepper (to taste)
    • 1 large red onion (sliced)

    Instructions
     

    • Remove roast from refrigerator at least 15-20 minutes before roasting.
    • Place oven rack in center position and pre-heat oven to 350°F.
    • Heat 1 tablespoon olive oil in a large, high-sided skillet over medium heat. Add the mushroom and shallots and season with salt and black pepper, to taste.

    • Arrange the mushroom and shallot mixture around the sides of the beef and place in the pre-heated oven until internal temperature with an instant read thermometer reaches 140°F for medium-rare, approximately 45-50 minutes.
    • Remove from oven and rest for 10-15 minutes before serving. Enjoy!
