Nothing beats a crockpot meal, except for maybe a crockpot meal that happens to be pork tenderloin! 😉

This slow cooker pork tenderloin turns out so juicy and flavorful, couldn’t be easier to make, and is always a hit with my friends and family.

We rub the pork in a simple seasoning blend, sear them in a hot skillet, and then pop them in the crockpot with a simple sweet and savory sauce.

Ingredients for crockpot pork tenderloin recipe.

Pork Tenderloins You’ll need about 3 pounds of pork tenderloin. This will likely come in on package as two tenderloins.

Seasoning – For the spice rub you’ll need some smoked paprika, onion powder, garlic powder, and salt. You’ll also need some red pepper flakes to go into the mixture with the soy sauce, broth, and sweetener.

Brown Sugar Substitute – We’re using our favorite brown sugar sweetener, Lakanto. You can easily find it on Amazon. It tastes and bakes just like real sugar, but it’s made with erythritol and monkfruit (both are all natural) so it has no impact on blood glucose.

Low Sodium Soy Sauce We love the flavor of soy sauce here, but you’ll want a low sodium version. You can also use coconut aminos if you avoid soy products.

Dijon Mustard This will get mixed up with the soy sauce, chicken broth, and sweetener to make the sauce for this crockpot pork tenderloin recipe.

Shop Keto Ingredients

We use Thrive Market for a lot of our specialty ingredients and keto snacks or products. Their prices tend to be cheaper than the local stores and I love that you can so easily sort products by diet.

Like Costco, this is a membership site, but we find that it’s more than worth it based on the amount we save over the regular grocery store.

They have monthly or yearly plans. Check it out here.

Why We Love This Recipe:

How To Make Pork Tenderloin:

  • Seasoning – To get started you’ll mix together the seasoning including the smoked paprika, onion powder, garlic powder, and salt. When combined start rubbing the spice mixture all over the pork tenderloin until it is well coated in the mixture.
  • Sear – Heat some oil in a large, heavy bottomed skillet over high heat. When it is good and hot add the pork and sear it on all sides. You don’t want to cook it through, just get a nice sear on the outside. It shouldn’t take long.
  • Sauce – After searing transfer the pork to a slow cooker and start preparing the sauce. Add the soy sauce, chicken broth, brown sugar substitute, Dijon mustard, and red pepper flakes to a small bowl and whisk them together until well combined. Pour it over the pork in the crockpot.
  • Slow Cook – When you’ve added the soy sauce and broth mix you can cover the crockpot and begin slow cooking on low for 4 hours or on high for 3 hours, or until the pork has reached an internal temperature of 145 degrees. I’ve linked to my favorite meat thermometer below!
  • Serve – The pork should be nice and tender and full of flavor after slow cooking in the spices and sauce. We’re not going for fork tender shreddable pork though. It should still be firm enough to slice it. We like to serve this crockpot pork tenderloin with something green like Szechuan green beans or some balsamic roasted Brussels sprouts!
Our Favorite Meat Thermometer

meat thermometer. I love using this meat thermometer for making sure the meat is fully cooked! Easy for beginners & absolutely worth the low cost. Just stick it in the thickest part of the meat to check for doneness. This thermometer is also magnetic so it’s easy to store right on the side of the fridge or oven for easy access! Get it on Amazon.

Pork tenderloin generally comes in a pack of 2, with each tenderloin around 1 1/2 pounds each.

This pork tenderloin will be very tender, but it's meant to be sliced and not shredded. If you'd like it tender enough to shred, you'll want to add more cook time.
