This AIP Pork Tenderloin is cooked to perfection. It’s juicy and tender with the amazing flavor of rosemary.

Does pork tenderloin get more tender the longer you cook it?
Pork tenderloin can be tricky because the meat is easy to overcook. Overcooking makes it dry and tasteless. Tenderloin doesn’t have enough fat to be cooked for a long time, even if at a low temperature.
My dad didn’t believe me when I told him how good this recipe tasted. He shook his head, disapprovingly, while he hovered over me while I cooked. After tasting it, he was pretty surprised that the pork was tender and not dried out. But if you follow the directions of this recipe, you won't have a problem. You’ll get tender, juicy and easy to chew pork every time.
What temperature should AIP Pork Tenderloin be cooked at?
You’ll need to set the temperature at 350 degrees for this recipe. And then roast for 20 minutes.
How long does pork tenderloin need to rest?
Once the pork is finished cooking, make sure to let is rest for 10 minutes. It will continue to cook and reabsorb its juices which keep it tender. If you cut into it right away, then all those juices spill out onto your cutting board and are lost.
Is it OK to eat pork tenderloin a little pink?
Yes, as long as the internal temperature comes to 145 degrees.

Tips to making the best AIP Pork Tenderloin
- If you would like to use dried rosemary, use 1 teaspoon. Dried rosemary is much more intense than fresh, and you won’t need as much.
- Make sure to use an oven safe pan. If you need help figuring out what pan is best. Check out this post on the Best Pans for Chemical Free Cooking.
- This recipe can easily be doubled as long as your pan is big enough for two pork tenderloins which are typically a few pounds each.

Great recipe! It was simple and quick to make, but the meat was tender and juicy. The rub added a nice hint of flavor without dominating the meat. Pan-fried sweet potatoes and aip coleslaw rounded out the meal and it was all on the table in 40 minutes.
That's great! I'm so glad you enjoyed this simple recipe. It's a favorite of my families as well.
