Recipe Tips
- This recipe calls for 2 small 1 pound tenderloins. You can also use just one 3 pound pork loin.
- Searing isn't required but always recommended. Helps seal in the juices and gives the meat some color.
- Pork tenderloin is a lean cut of meat that can dry out if overcooked. Use a meat thermometer to check the temperature and remove it when it's 145 degrees.
- You could add some potatoes, onions, and carrots in with the pork tenderloin
- Whisking in a little cornstarch to the sauce and it becomes a delicious silky gravy. Poured over my Garlic Roasted Mashed Potatoes is fantastic!
- Do not add any more liquid to the slow cooker. The tenderloin will make its own juices.

Fantastic Leslie, I love it when I hear picky eaters that love my recipes 🙂
This is, by far, the best pork tenderloin I’ve ever made! I have 3 kids that are VERY hard to please..they all said it’s the best. This is the first recipe I’ve left a comment on...I’m not sure why, because every recipe I’ve made of yours has been delicious. Thank you for sharing your creations!!
Pork tenderloin is a very lean cut and can dry out easily if overcooked. It will work but the cooking time will need to be adjusted considerably and I can't say by how much without having more info. Pork is done when it reaches 145 degrees.
Pork tenderloin is strangely very expensive in my area right now. However thick pork loin chops are half the price. Think the chops would work out as a substitute? Time adjustment?
Yay Cindy! So happy you loved it thanks for the great review 🙂
Very easy recipe, and delicious! So tender, and the red pepper flakes gives it the perfect kick! 🙂 Making again this evening.
After the tenderloin is finished cooking. Transfer the juices back into a skillet and whisk in the chicken stock and cornstarch to make the gravy. There is also a video to watch above in the post 🙂
Confused the chicken stock at what point iis it added
Great idea Annette!
So delicious. I used a quarter teaspoon of xanthan gum, instead of cornstarch, to make it low carb. Just add directly to the hot liquid and continue following the directions. I served it with green beans and mashed cauliflower.
