Despite being very lean, pork tenderloin is exceptionally tender, making it an ideal option for a healthy dinner. Make an effortless yet mouthwatering meal by preparing the tenderloin in the morning and letting your Crock-Pot take care of the rest. Italian salad dressing infuses the pork with the flavors of garlic, herbs and other spices. Store-bought dressing works just fine, but a simple homemade dressing probably contains less sodium and sugar than bottled versions.
Heat a tablespoon of oil in a large skillet over medium-high heat. Sear the tenderloin in the skillet until it is browned on all sides, about two to three minutes per side.
Transfer the tenderloin to the slow-cooker and pour the salad dressing over the top of the pork. Use about 1/2 cup of salad dressing for every pound of meat.
Add aromatics and chopped vegetables to the slow-cooker, if you wish. Choose from garlic, bay leaves, dried herbs, onions, carrots and celery.
Cover the slow-cooker and cook on high for four to five hours or low for six to seven hours. Cut the finished pork into slices to serve.
Always cook whole cuts of pork to a minimum internal temperature of 145 degrees Fahrenheit to guarantee safety.
