Why Pork Tenderloin Works So Well in the Slow Cooker
Pork tenderloin is one of the leanest cuts of pork, which means it can dry out quickly if overcooked in the oven. The slow cooker solves that problem entirely. The gentle, moist heat keeps every bite succulent and flavorful, and the cooking juices that collect at the bottom make a naturally delicious sauce you can spoon right over the meat when serving.
Ingredients
- 1 whole pork tenderloin (approximately 1 to 1.5 pounds)
- 1 packet dry onion soup mix
- 1/2 cup chicken broth
- 2 tablespoons soy sauce
- 2 tablespoons brown sugar
Method
- Place the pork tenderloin directly into the bottom of your slow cooker insert, just as you see it — no browning or searing required.
- In a small bowl, whisk together the dry onion soup mix, chicken broth, soy sauce, and brown sugar until the sugar dissolves.
- Pour the mixture evenly over the top of the pork tenderloin, making sure it is well coated.
- Place the lid on the slow cooker and cook on low for 6 to 7 hours, or on high for 3 to 4 hours, until the pork is completely tender and cooked through.
- Remove the tenderloin from the slow cooker and let it rest for about 5 minutes before slicing. Spoon the rich cooking juices from the bottom of the pot over each serving.
Serving Suggestions
This pork tenderloin pairs beautifully with creamy mashed potatoes, steamed rice, roasted vegetables, or buttered egg noodles. The savory, slightly sweet cooking sauce doubles as a gravy, so do not waste a single drop of it.
Tips for the Best Results
Make sure your tenderloin fits comfortably in the slow cooker. If it is too long, you can trim it slightly or curl it to fit. Avoid lifting the lid during cooking, as this releases heat and extends the cooking time. Leftovers store well in the refrigerator for up to three days and reheat beautifully with a splash of broth to keep the meat moist.
