Ingredient Notes & Details

Pork Tenderloin

Choose one or two fresh pork tenderloins, depending on the size. Pork tenderloin is naturally lean, making it ideal for an easy Slow Cooker Pork Tenderloin recipe that still turns out juicy when cooked properly.

Olive Oil

A little olive oil helps the seasonings stick to the meat and adds richness. Avocado oil also works well.

Garlic

Fresh minced garlic creates the best flavor, but garlic paste or garlic powder may be substituted if needed.

Onion

Yellow onions become wonderfully soft during cooking and add natural sweetness to the cooking liquid.

Chicken Broth

Low-sodium chicken broth creates a flavorful base while keeping the pork moist throughout cooking.

Soy Sauce

Adds savory depth and balances the richness of the pork. Low-sodium soy sauce is recommended.

Dijon Mustard

Provides subtle tanginess without overpowering the dish. Whole grain mustard can also be used for extra texture.

Honey

Just a touch helps balance the savory flavors while encouraging a beautiful glaze.

Italian Seasoning

A blend of herbs brings warmth and classic flavor to this Slow Cooker Pork Tenderloin.

Paprika

Sweet paprika adds gentle smokiness and beautiful color.

Black Pepper

Freshly ground pepper gives the best flavor.

Salt

Adjust according to the saltiness of your broth and soy sauce.

Fresh Thyme or Rosemary

Fresh herbs add wonderful aroma, though dried herbs can be substituted if necessary.

Cornstarch (Optional)

If you’d like a thicker gravy, whisk cornstarch with cold water before stirring it into the cooking liquid near the end.

Step-by-Step Instructions

Step 1: Prepare the Pork

Pat the pork tenderloin completely dry using paper towels. Removing excess moisture helps the seasoning adhere evenly and improves flavor.

Season all sides generously with salt, black pepper, paprika, and Italian seasoning.

Allow the meat to sit for about 10 minutes while you prepare the remaining ingredients.

Step 2: Layer the Slow Cooker

Scatter the sliced onions across the bottom of the slow cooker.

Add the minced garlic over the onions so it slowly infuses the cooking liquid without burning.

Place the seasoned pork tenderloin directly on top.

Step 3: Mix the Sauce

In a small bowl, whisk together the chicken broth, soy sauce, Dijon mustard, and honey until smooth.

Pour the mixture evenly around the pork rather than directly over the top to help keep the seasoning intact.

Add fresh thyme or rosemary.

Step 4: Slow Cook

Cover with the lid.

Cook on LOW for 2½ to 4 hours, depending on the size of the tenderloin, or on HIGH for 1½ to 2½ hours.

The pork is done when the thickest portion reaches an internal temperature of 145°F (63°C).

Avoid overcooking, as pork tenderloin is much leaner than pork loin and cooks relatively quickly.

Step 5: Rest Before Slicing

Transfer the cooked pork to a cutting board.

Tent loosely with foil and allow it to rest for at least 10 minutes.

Resting helps the juices redistribute throughout the meat, keeping every slice moist.

Step 6: Make the Gravy (Optional)

If you’d like a thicker sauce, whisk together cornstarch and cold water until smooth.

Stir the slurry into the hot cooking liquid.

Cook on HIGH for another 10 to 15 minutes until the gravy thickens into a silky sauce.

Step 7: Slice and Serve

Slice the pork into medallions about ½ inch thick.

Spoon the warm gravy and softened onions over each serving.

Serve immediately alongside your favorite vegetables or potatoes for a comforting family dinner.

FAQ for Common Questions

Can you overcook Slow Cooker Pork Tenderloin?

Yes. Because pork tenderloin is naturally lean, cooking it too long may cause it to become dry. Use a meat thermometer and remove it once it reaches 145°F.

Should I sear pork tenderloin before slow cooking?

Searing is optional but recommended. It develops additional flavor and creates a richer finished dish, though the recipe is still delicious without this step.

Is Slow Cooker Pork Tenderloin healthy?

Yes. Pork tenderloin is one of the leanest cuts of pork and works well in balanced, high-protein meals. It’s also suitable for many low carb Slow Cooker Pork Tenderloin meal plans when served with vegetables.

Can I make this recipe ahead of time?

Absolutely. Cook the pork earlier in the day, refrigerate it, and gently reheat before serving with the reserved cooking juices.

Can frozen pork tenderloin go directly into the slow cooker?

For food safety, thaw the pork completely in the refrigerator before slow cooking to ensure even cooking.

What’s the difference between pork loin and pork tenderloin?

Pork tenderloin is much smaller, leaner, and cooks faster. Pork loin is larger and requires significantly longer cooking times.

Storage Tips

Refrigeration

Allow the pork to cool within 2 hours of cooking. Store sliced pork and its cooking juices in an airtight container in the refrigerator for up to 4 days. Keeping the meat with the juices helps preserve moisture.

Freezing

Slice or leave the pork whole before freezing. Store in freezer-safe containers or bags with some of the cooking liquid for up to 3 months. Thaw overnight in the refrigerator before reheating.

Reheating

Warm gently in a covered skillet over low heat with a splash of broth or reserved juices until heated through. You can also reheat individual portions in the microwave at reduced power to prevent the meat from drying out. Reheat leftovers to 165°F (74°C) before serving.

• 2 tablespoons Worcestershire sauce
• 1 tablespoon Dijon mustard
• 2 tablespoons unsalted butter cut into small pieces
• 1 tablespoon cornstarch
• 2 tablespoons cold water

Instructions

Pat the pork tenderloin dry with paper towels. Rub it all over with the olive oil.

In a small bowl, combine the salt, black pepper, smoked paprika, garlic powder, onion powder, thyme, rosemary, and red pepper flakes if using. Coat the pork evenly with the seasoning mixture.

Place the seasoned pork tenderloin into the slow cooker.

In a measuring cup, whisk together the chicken broth, Worcestershire sauce, and Dijon mustard. Pour the mixture around the pork. Scatter the butter pieces over the top.

Cover and cook on LOW for 3 to 4 hours, or until the thickest part of the pork reaches an internal temperature of 145°F (63°C).

Meanwhile, pour the cooking liquid into a small saucepan. Mix the cornstarch with the cold water until smooth, then stir it into the liquid. Bring to a gentle simmer over medium heat, stirring frequently, until the sauce thickens, about 2 to 3 minutes.

Slice the pork into medallions and serve with the warm gravy spooned over the top.
