A turkey tenderloin -- the boneless strip of white meat found under the breast -- makes a perfect entrée for an elegant dinner or a casual Sunday brunch. The average turkey tenderloin weighs 8 to 16 ounces, and is a low-fat source of protein. Preparing a tenderloin in a slow cooker, such as a Crock-Pot, creates an entree that is fork-tender and succulent. Toss in chunks of vegetables for a ready-to-serve meal that doesn't leave you with multiple pots and skillets to wash. For an extra flavor kick, sprinkle the turkey with a blend of savory herbs and spices, or add a fruity sweetness with a touch of jam.
Spread the red potatoes, carrots and onions across the bottom of the slow cooker.
Sprinkle salt and pepper on all sides of the tenderloin. Lay it across the vegetables in the slow cooker.
Pour the broth over the tenderloin and vegetables.
Spoon 1/3 cup orange marmalade or apricot jelly over it.
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 Fahrenheit. If it's not, continue cooking for 15 minutes on high or 30 minutes on low and check again.
Remove the tenderloin and allow to rest for 10 minutes. Slice the meat, then arrange the slices and vegetables on a platter and serve.
