• 1 teaspoon dried Italian seasoning

• ½ teaspoon onion powder

• ½ teaspoon black pepper

• ¾ teaspoon salt

For the Garlic Butter Sauce

• 4 tablespoons unsalted butter

• 5 garlic cloves, minced

• ½ cup low-sodium chicken broth

• 2 tablespoons Worcestershire sauce

• 1 tablespoon Dijon mustard

• 1 tablespoon honey

• 1 teaspoon dried thyme

• 1 teaspoon fresh lemon juice

For Thickening the Sauce (Optional)

• 1 tablespoon cornstarch

• 2 tablespoons cold water

For Garnishing

• 2 tablespoons freshly chopped parsley

• Freshly ground black pepper

• Lemon wedges

Step-by-Step Instructions

Step 1: Prepare the Pork Tenderloin

Remove the pork tenderloin from its packaging and pat it dry with paper towels.

Trim away any visible silver skin using a sharp knife.

In a small bowl, combine garlic powder, smoked paprika, Italian seasoning, onion powder, salt, and black pepper.

Rub the seasoning mixture evenly over the pork tenderloin.

Step 2: Sear the Pork

Heat olive oil in a large skillet over medium-high heat.

Add the seasoned pork tenderloin and sear for approximately 1–2 minutes per side until lightly browned.

The meat does not need to be fully cooked.

This optional step creates a flavorful golden crust and enhances the finished dish.

Step 3: Prepare the Garlic Butter Sauce

Melt the butter in a small saucepan over medium-low heat.

Add minced garlic and cook for approximately 30–60 seconds until fragrant.

Stir in chicken broth, Worcestershire sauce, Dijon mustard, honey, dried thyme, and lemon juice.

Mix until the ingredients are well combined.

Step 4: Place the Pork in the Slow Cooker

Lightly grease the inside of a 4–6-quart slow cooker.

Place the seasoned pork tenderloin in the center.

Pour the prepared garlic butter sauce evenly over the meat.

Turn the tenderloin once to coat it with the sauce.

Step 5: Slow Cook Until Tender

Cover the slow cooker with its lid.

Cook on LOW for approximately 2–3 hours, depending on the thickness of the tenderloin and your slow cooker.

Begin checking the internal temperature early to avoid overcooking.

The pork is safely cooked when the thickest part reaches 145°F (63°C), followed by a 3-minute rest.

Avoid cooking pork tenderloin for 6–8 hours because this lean cut can become dry.

Step 6: Rest the Pork Tenderloin

Carefully remove the cooked pork tenderloin from the slow cooker.

Transfer it to a cutting board and loosely cover it with aluminum foil.

Allow the meat to rest for approximately 5–10 minutes before slicing.

Resting helps retain the natural juices.

Step 7: Thicken the Garlic Butter Sauce

For a thicker sauce, transfer the cooking liquid to a small saucepan.

Bring it to a gentle simmer.

Mix cornstarch with cold water until smooth.

Slowly whisk the mixture into the simmering sauce.

Cook for 2–3 minutes until slightly thickened.

Step 8: Slice and Serve

Slice the pork tenderloin into thick, even pieces.

Arrange the slices on a serving platter.

Spoon the warm garlic butter sauce generously over the meat.

Garnish with freshly chopped parsley and black pepper.

Serve immediately with your favorite side dishes.

Tips and Notes

1. Choose Pork Tenderloin, Not Pork Loin: Pork tenderloin is smaller, leaner, and cooks much faster than a large pork loin roast.

2. Sear for Extra Flavor: Browning the meat before slow cooking creates a delicious outer crust.

3. Use Fresh Garlic: Freshly minced garlic gives the butter sauce a richer flavor.

4. Avoid Overcooking: Pork tenderloin is lean and can dry out when cooked too long.

5. Use a Meat Thermometer: Checking the internal temperature is the most reliable way to ensure juicy, safely cooked pork.

6. Add Vegetables: Baby potatoes, carrots, or mushrooms can be added, but dense vegetables may need a head start to become tender before the pork is done.

7. Adjust the Sweetness: Reduce the honey if you prefer a more savory garlic butter sauce.

8. Make It Creamy: Stir a small splash of heavy cream into the finished sauce for a richer texture.

9. Store Leftovers Properly: Refrigerate cooked pork in an airtight container within 2 hours and use within 3–4 days.

10. Slice Against the Grain: Cutting across the muscle fibers helps create more tender slices.

Frequently Asked Questions (Q&A)

1. Can I Cook Pork Tenderloin Without Searing It First?

Yes. You can place the seasoned pork directly into the slow cooker. Searing is optional, although it adds extra flavor.

2. Can I Use Frozen Pork Tenderloin?

Thaw the pork completely in the refrigerator before slow cooking. Frozen meat should not be cooked directly in a slow cooker.

3. Can I Use Pork Loin Instead?

Yes, but pork loin is a different cut and requires a different cooking time. Use a meat thermometer to determine doneness.

4. How Do I Keep Pork Tenderloin Juicy?

Cook it on LOW, check the temperature early, and allow it to rest before slicing.

5. Can I Add Potatoes to the Slow Cooker?

Yes. Small diced potatoes work well, but they may need additional cooking time. Partially cook them before adding if necessary.

6. Can I Make This Recipe Ahead of Time?

Yes. You can prepare the seasoning and garlic butter sauce in advance and refrigerate them separately until ready to cook.

7. Can I Freeze Leftover Pork Tenderloin?

Yes. Freeze cooled, cooked pork in airtight freezer-safe containers for up to 2–3 months for best quality.

8. How Should I Reheat Leftovers?

Reheat the pork gently with a little sauce or broth until thoroughly hot, reaching 165°F (74°C).
