How to make Keto Pork Tenderloin
1. Prepare herb mixture: In a small plate prepare the herb mixture by mixing chopped garlic, Herbs de Provence, Italian Seasoning and coarse sea salt.

2. Place the tenderloin in the oven safe dish, such as cast iron, dutch oven or on a baking sheet. Using a knife, make 5-6 small cuts across the tenderloin.

3. Stuff herb and garlic mixture into the cuts of the tenderloin.

4. Cover the tenderloin with the remaining mixture on top and gently pour olive oil over the tenderloin to cover it.

Bake at 350 F. for approximately 30 minutes until meat thermometer reads at least 145 F (for pink tenderloin) or 160 F (for white tenderloin).
Slice it and spoon juices from the pan over the tenderloin. Sprinkle with fresh thyme leaves and the low carb pork tenderloin is ready to be served!

Margot says
My husband made this, but cooked it on the grill. The flavor was wonderful, but it was very dried out. How could we make it juicier?
Olya says
Pork tends to dry out so fast when grilling. Maybe tenderize it with lemon juice for half an hour before grilling?
Squeaky says
This was really delicious and the kids ate it all up as well! I really didn't think they would with all that "stuff" on the top! Ha! Was fantastic served with sauteed kale and onions. I also made rice for the kids. There was a small piece leftover, and it was really nice just cold.
I made it in cast iron like your pictures, but I preheated the pan while I prepped the rest of the meal so the underside had a tasty sear on it.
I bought 2 tenderlions and froze one so we will be having this again next week.
Olga says
Haha - I'm glad they liked it despite all that "stuff" on the top!

Is there a way to print this recipe? I see the sweet print button but nothing happens.
Olga says
What browser are you using?
Julia Ferguson says
I use Chrome. I used that as a print option, found the page as #13 and printed just that page. We are cooking it tonight. The reason I had asked was because with the print thru browser option things are screwed and other things showed up such as a search drop down button over the ingredients so I just printed and wrote in what was blocked.
Thanks for responding.
Olga says
I'll test it on Chrome today. I also have a button at the very top of the post (under the title) that allows you to print without scrolling all the way to the bottom.
Lynn Ellisy says
How big is the tenderloin?
Olga at Whatsinthepan says
It was about one pound, in term of the size - the skillet I used in the recipe is 9 inches, so it was pretty long, but thin.
