Ingredients

For about 4–6 servings, you’ll need:

For the Pork

1½–2 pounds pork tenderloin
1 tablespoon olive oil
1 teaspoon salt
½ teaspoon black pepper
1 teaspoon paprika
1 teaspoon garlic powder
½ teaspoon onion powder
½ teaspoon dried thyme
½ teaspoon dried rosemary

For the Slow Cooker Sauce

4 cloves garlic, minced
1 cup chicken or vegetable broth
2 tablespoons low-sodium soy sauce
2 tablespoons honey or brown sugar
1 tablespoon Dijon mustard
1 tablespoon apple cider vinegar
1 small onion, thinly sliced

Optional Thickener

If you want a thicker sauce or gravy:

1 tablespoon cornstarch
2 tablespoons cold water

Step 1: Prepare the Pork Tenderloin

Begin by removing the pork tenderloin from its packaging and patting it dry with paper towels.

This small step is useful because removing excess moisture helps the seasoning adhere better to the meat.

If your tenderloin has a visible strip of tough silver skin, carefully trim it away with a sharp knife while leaving the meat intact.

Next, combine the salt, pepper, paprika, garlic powder, onion powder, thyme, and rosemary in a small bowl.

Rub the seasoning mixture evenly over every surface of the pork.

Step 2: Sear the Pork for Extra Flavor

Although you can place the seasoned pork directly into the slow cooker, quickly searing it first adds another layer of flavor.

Heat the olive oil in a large skillet over medium-high heat. Once hot, place the pork in the skillet and brown it briefly on several sides.

You aren’t trying to cook the pork through at this stage. The purpose is simply to develop a flavorful browned exterior.

Once browned, transfer the tenderloin to the slow cooker.

Shortcut: If you’re in a hurry, you can skip this step. The finished dish will still be delicious, although it won’t have quite the same browned flavor.

Step 3: Build the Sauce

Add the sliced onion and minced garlic around the pork.

In a bowl, whisk together the broth, soy sauce, honey, Dijon mustard, and apple cider vinegar.

The combination creates a sauce that is savory, slightly sweet, and pleasantly tangy. The mustard also adds a subtle depth without making the dish taste strongly of mustard.

Pour the sauce around and over the pork.
