Ingredients

  • 2 pork tenderloins (about 1 pound each)
  • ½ teaspoon salt
  • ½ teaspoon black pepper
  • 2 Tablespoons olive oil
  • ½ cup low-sodium beef broth
  • 1 packet pork gravy mix
  • 4 Tablespoons salted butter, thinly sliced

Instructions

  • Season the pork tenderloins with 1/2 teaspoon salt and 1/2 teaspoon black pepper all over (this is the total amount of seasoning for both pork tenderloins, you can use more or lest to taste).

  • In a large skillet over medium-high heat, add 2 Tablespoons olive oil. Once hot, sear one pork tenderloin at a time on all sides until browned. Place the seared tenderloin on top of the onions in the slow cooker. Repeat with the other tenderloin.
    NOTE: You are not cooking the tenderloins, you are just giving them some color so don't keep them on the heat longer than necessary.

  • Add 4 Tablespoons salted butter, thinly sliced on top of each tenderloin.

  • Cover and cook on low for 2 - 2.5 hours or until an internal temperature reaches at least 145°F and the onions are softened, or until your desired internal temperature.
    NOTE: Once you cover the slow cooker, do not keep removing the cover to check on it. This will result in a longer cooking time and the meat can come out tough. Just cover it and leave it alone.

Notes

  • Please refer to my FAQ’s (Frequently Asked Questions) and ingredient list above for other substitutions or for the answers to the most common questions.
  • The seasoning is very simple as I wanted to keep the recipe simple. You're getting flavors from the pork gravy packet and onion. Please feel free to experiment with seasonings and additional flavors. I think adding garlic would be a wonderful touch! 
  • Want a thicker gravy? Try mixing 2 Tablespoons water with Tablespoons cornstarch. Add to the slow cooker and stir. Turn on high for about 30 minutes or until thickened.
