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 keto stuffed 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!

How to make this keto Pork Tenderloin recipe 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.

This mushroom sauce for the stuffed pork tenderloin is packed with flavor!

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 also 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.

Below you can see how I how I did all this.

The filling of this stuffed pork tenderloin

This is really a very simple pork recipe and the filling is only provolone, 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.

Even if you can keep the pork together it will taste delicious!

Cooking the meat and making the 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.

Keto Stuffed Pork Tenderloin with mushrooms sauce

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 low carb cauliflower rice. I hit a home run with these dishes. Enjoy! The nutritional content for 1 serving is:
