Turkey tenderloin is a low-fat source of protein with a mild flavor and succulent texture. Cook the tenderloin in a slow cooker such as a Crock-Pot, for an entree that is fork-tender and infused with moist flavor. Toss a few servings of root vegetables into the slow cooker with the turkey for a ready-to-serve meal that doesn't leave you with multiple pots and skillets to wash. The tenderloin will readily soak up the flavor of any additional herbs and spices you add.
Spread the red potatoes, carrots and onion across the bottom of the slow cooker.
Salt and pepper the tenderloin on all sides. Lay it across the vegetables in the slow cooker.
Pour broth over the tenderloin and vegetables.
Spoon 1/3 cup orange marmalade or apricot jelly, if using, over the tenderloin.
Cover the slow cooker. Cook the tenderloin on high for four to five hours, or cook on high for one hour and low for six or seven hours. Insert a food thermometer into the center of the tenderloin and make sure the internal temperature is at least 165 degrees F. If it is not, cook the tenderloin for 15 minutes on high or 30 minutes on low and check again.
