How to Make Slow Cooker Pork Tenderloin
1. Prepare the Slow Cooker
Lightly grease the slow cooker or add a thin layer of sliced onions to the bottom to prevent sticking and add flavor.
2. Add the Pork
Place the raw pork tenderloin directly into the slow cooker. There’s no need to sear it beforehand.
3. Mix the Sauce
In a small bowl, combine broth, soy sauce (or Worcestershire), garlic, brown sugar, paprika, and olive oil. Stir well.
4. Pour and Season
Pour the mixture over the pork, making sure it coats the meat. Add sliced onions and fresh herbs on top if using.
5. Slow Cook
Cover and cook:
Low: 6–7 hours
High: 3–4 hours
The pork is ready when it’s fork-tender and easily slices.
6. Rest and Slice
Remove the pork and let it rest for 5–10 minutes. Slice against the grain for maximum tenderness.
Optional: Make a Rich Sauce
For a thicker sauce, pour the cooking liquid into a saucepan and simmer for 5–10 minutes until slightly reduced. Spoon it over the sliced pork before serving.
