4-Ingredient Slow Cooker Vintage Pork Tenderloin
Servings: 6
Ingredients
1 pork tenderloin, about 1 to 1 1/2 pounds
Directions
1. Place the raw pork tenderloin in the bottom of your slow cooker.
2. In a small bowl, stir together the dry onion soup mix, cream of mushroom soup, and water until combined.
3. Pour the soup mixture over the pork tenderloin, covering the top as evenly as you can.
4. Cover and cook on low for 4 to 6 hours, or until the pork is tender and cooked through. If you like, spoon some of the sauce over the pork once or twice during cooking.
5. Transfer the pork to a cutting board, let it rest for 5 minutes, then slice and serve with the sauce from the slow cooker spooned over the top.
Variations & Tips
For extra flavor: Brown the pork tenderloin in a skillet with a little oil for 2 to 3 minutes per side before adding it to the slow cooker. This is optional, but it gives the finished dish a deeper, roasted flavor.
For picky eaters: If your family prefers a smoother sauce, whisk the cream of mushroom soup mixture very well before pouring it over the pork so everything blends nicely. You can also serve the sauce on the side and let everyone add their own.
To keep it from drying out: Pork tenderloin is leaner than pork loin, so check it on the earlier side of the cooking range. Once it is tender and cooked through, go ahead and turn off the slow cooker to keep the slices nice and juicy.
Easy side swap: This recipe is especially good over rice, noodles, or mashed potatoes, but it also works beautifully tucked into a toasted sandwich roll with a spoonful of sauce for leftovers the next day.
