If you are looking for a delicious dinner to bring the family around the table, this pork tenderloin recipe should be next up in your menu rotation. We whisk together a simple sauce and combine it with pork and vegetables in the slow cooker. It leaves you with a mouth watering complete dinner at the end of your busy day.

How to Pork Tenderloin in Crock Pot

  1. Whisk together sauce: Combine beef stock, red wine, garlic, soy sauce, paprika, and onion powder.
  2. Prepare slow cooker: Spray the slow cooker with cooking spray.
  3. Add ingredients: First place the pork tenderloin in the slow cooker. Then surrounded it with chopped onions and carrots. Top everything with the sauce. Finally add fresh sprigs of rosemary and thyme.
  4. Cook: It takes 3 hours for pork tenderloin to cook in a crock pot. If your vegetables aren’t done when the pork is, remove the pork and tent it with foil. Place the vegetables on a foil lined tray and place them in a 425 degree oven for 10 to 15 minutes until tender.

Pork Tenderloin Temperature

Pork tenderloin is done when it reaches 145 degrees. It is best, when cooking it in the slow cooker, to be mindful of this and towards the end of the cooking time check it with an instant read thermometer.

Pork is far more delicious when cooked to 145 degrees and not hotter. At 145 degrees, it will still have a pink hue to it, but that does not mean it isn’t done.

Pork Tenderloin vs. Pork Loin

When buying meat for this recipe, note that pork tenderloin and pork loin are two different cuts of pig. Pork loin is a bigger cut of meat and is often used by the butcher to cut pork steaks. Alternatively, pork tenderloin is a smaller, thinner and more tender cut of pork.

Cooking with Red Wine

I love the deep and earthy flavors of this recipe, and one thing that adds to that is red wine. If your family does not drink, you can buy a four pack of small bottles of red wine to use for this recipe. This will save you from opening an entire bottle only for 3/4 of a cup.

If your family does not use alcohol in recipes, I would suggest using beef stock as a replacement for the wine.

Dry Herbs vs. Fresh Herbs

Fresh herbs can be expensive. If they aren’t in your budget or you can’t find them, replace them with 1 teaspoon dried rosemary and 1 teaspoon dried thyme. You can whisk them right into the sauce.

Making Gravy

The cooking liquid for this recipe makes a great gravy.

  1. Discard the herbs and remove the meat and vegetables from the slow cooker.
  2. Strain the remaining liquid.
  3. Whisk it with 1 tablespoon corn starch in a small saucepan.
  4. Bring to a boil and simmer for 10 minutes until it thickens.

    Lisa,

    I just love your dinner ideas. esp. the crock pot dinners.

    Thank you

    Lois Whitham

    • Lisa Longley says

      Thank you Lois!

  2. smex says

    Lisa,
    Can this cook all day while away at work 8-9 hrs or will it dry out if cooked that long?

    • Lisa Longley says

      Unfortunately, no. I actually had to test this recipe a few times to find the cooking time that lead to the perfect tenderness without it drying out.

  3. Sherry says

    This looks yummy, but is it cooked on low or high?

    • Lisa Longley says

      It is cooked on low.

  4. Chelsie says

    Could I add baby potatoes in the crock pot to this as well or would you recommend making them separate?

    • Lisa Longley says

      If they are small or cut in half they should work.

    I had some fresh mushrooms that needed cooked and I threw those in but otherwise stuck to the recipe. It was a hard sell to get my mother in law to eat pork with a slight pink hue, lol. I usually have to turn her pork into shoe leather and cook everyone else’s correctly. But it turned out really great. Thank you!

    • Lisa Longley says

      Ha!! Thank you for the laugh. And I’m glad you got her to eat it! There is nothing worse than overcooked pork.

    I made this and added small potatoes and first covered the pork loin with Dijon mustard and seasoned it all over let it sit for 30 minutes with the dry seasoning. O my god the flavor was incredible. This is a keeper and the wine definitely makes the dish!!!!!!

    • Lisa Longley says

      I’m so glad that you liked it!

    I cook it like it said, it was tuff so I let it cook a little longer, this is knot a good resipe to make for pork tenderloin, sorry.

    • Lisa Longley says

      I’m so sorry this was a miss for you. If it was tough it means it cooked too long. I do my best to give estimates but slow cookers vary so much that it can be hard to be precise.

    I just cooked this for a quick, easy Xmas dinner, and it turned out so wonderful! Very tender and tasty. I had never cooked a pork tenderloin in the crockpot. I will be making this again! Thanks for the recipe.

    • Lisa Longley says

      I’m so glad that you liked it, Carey!

  9. ESTELLA ETNIER says

    First, we love your sauce but following your recipe gave us a tough piece of me. I followed the recipe exact…. In the future, I will use your sauc but not your three hours. I will cook it till it falls apart which is what happened every time I cooked a lion in my crockpot….Yummy flavor..

    • Lisa Longley says

      With tenderloin, it’s not really going to fall apart because it’s such a low fat piece of meat. The key is to really cook it only to 145. That can be tricky with slow cookers because they all cook at different temperatures. So an instant read thermometer can be really helpful. Is it possible that you used a pork loin? That would give the results you are talking about here.
