I had a package of thinly sliced steaks in the freezer that I intended to use this recipe with. However when I took them out of the freezer they didn’t look so good so plan B. I had a pork tenderloin to make my creamy pork & apples dish but thought I’d use it instead for this stuffed keto pork tenderloin with mushroom sauce.

Oh my it was good! My husband raved about it for 2 days. I was happy because it’s low carb (3.2g net carbs) and he was happy because it was so tasty. I have another pork tenderloin so I think I’m going to make it again next week!

Stuffed keto Pork Tenderloin in a nutshell:

  • cut the pork tenderloin lengthwise but not all the way through so that you can open it like a book 
  • pound flat with a meat tenderizer and as thin as you can so you can roll it up better
  • rub crushed garlic on the inside along with salt and pepper.
  • layer with cheese and spinach and then roll up using kitchen twine or toothpicks. 
  • brown the meat on both sides in an oven proof skillet
  • place it in the oven to bake and then start your mushroom sauce
  • saute mushrooms in butter and add beef stock, balsamic vinegar and garlic
  • cook down and at the end add a bit of cream
  • pour over your meat when it comes out of the oven.

The filling of this stuffed pork

It’s a very simple recipe as the filling is only provolone and spinach and some crushed garlic rubbed on the inside. The hardest part is keeping the meat together. I didn’t have any kitchen twine and used toothpicks unsuccessfully. As you an see it didn’t really matter much. It still tasted great and didn’t look all that bad.

 

Preparing the pork tenderloin

So all you need to do is cut the pork loin lengthwise but not all the way through. Just enough so that you can open it like a book and then pound flat with a meat tenderizer like this. You can all use a heavy pan but the mallot is much easier. You want to pound it as thin as you can so you can roll it up better.

Then rub crushed garlic on the inside along with a sprinkle of salt and pepper. Layer with cheese and spinach and then roll up. If you have kitchen twine, use that to keep it closed. Otherwise use toothpicks.

Cooking the meat and mushroom sauce

Next you brown the meat on both sides in an oven proof skillet. Place it in the oven to bake and then start your mushroom sauce. I use Better than Bouillon to make my beef stock because it has so much flavor. But you can use beef stock instead.

Saute some mushrooms in butter and add some beef stock and balsamic vinegar and garlic. Let that cook down and at the end add a bit of cream and pour over your meat when it comes out of the oven.

I don’t know what I liked better the stuffed pork tenderloin or the mushroom sauce.  The mushroom sauce would go great on a steak or just about any other meat. I always keep a pork tenderloin in the freezer for recipes like this.

I buy them at Aldi and with just a few simple ingredients you have a wonderful hearty meal like this. Tonight I served it with a some festive cauliflower rice. I hit a home run with these dishes. Enjoy! The nutritional content for 1 serving is:

    Hi. I’m going to make this for dinner. I don’t see where you used the second tablespoon of oil. Was butter substituted for oil in the sauce?

      Hi Peggy,
      I have no idea why I did that? 🙂 I would just use 1 – 2 tablespoons of oil to brown the meat. Keep the butter for the sauce. Sorry about that! Thanks for bringing that to my attention and I hope you enjoy it!

      Hi Tammy,
      First let me say that I used pork tenderloin which is more tender than the pork loin you have. Just wanted to let you know that. That being said I think you should cut the pork loin into pieces as you said. Not sure what the diameter is but hopefully you can pound it thin enough so you can roll it. As you can see I didn’t do such a great job of it but it was very tasty. I hope it works for you! Let me know if you have any other questions.

      Hi Madeline,
      I think you prepare the meat – pound, stuff and wrap up with twine – ahead of time. You could probably make the sauce ahead of time and just heat it up in the microwave and pour over the meat when it’s done. I have not done this but I don’t know why it wouldn’t work. Good luck!

    Made this recipe last night. It was delicious. The pork was so flavorful and the mushroom sauce tasted like something we had in Germany. Where has this website been all of my low carb life?? So many wonderful recipes that I want to try.
