Tips for the Best Slow Cooker Pork Tenderloin
Add Fresh Onion for Extra Flavor
Layer a thinly sliced yellow onion beneath the pork before cooking for deeper onion flavor and texture.
Make the Gravy Creamier
Stir in a few tablespoons of sour cream after cooking for a rich, creamy finish.
Thicken the Sauce
For a thicker gravy:
- Mix 1 tablespoon cornstarch
- Add 2 tablespoons cold water
- Stir into the hot gravy
- Cook on HIGH for 10–15 minutes
Avoid Overcooking
Pork tenderloin is lean and cooks faster than pork loin. Check for doneness toward the lower end of the cooking range.
Storage and Meal Prep
Refrigeration
Store leftovers in an airtight container for up to 4 days.
Freezing
Freeze cooled pork and gravy for up to 3 months.
Reheating
Warm gently on the stovetop or in the microwave until heated through.
Adding a splash of broth helps maintain moisture.
