This low carb pork tenderloin recipe is smoked with a homemade dry rub and bursting with flavor! We served it with my tomatillo pico de gallo and could not get enough. Next time, I think we’ll make two! This is easily the best pork tenderloin recipe I’ve ever made, and an additional tenderloin would be SO easy to portion out as meal prep for the week.
Don’t forget to Pin it for later! ?
I could eat this pork tenderloin over and over without tiring, making it an excellent meal prep candidate!
Pork tenderloin is lean and tender, which can make it a pretty unforgiving cut of meat if it’s overcooked; once it’s overdone, it becomes tough and chewy. Get the temperature right? So delicate and tender. Be sure to keep your eye on the heat while it’s on the smoker!
I like my pork tenderloin medium, so when I’m using it for meal prep, I cook it to medium rare instead of my desired temp. That way it doesn’t overcook when I reheat it. Just a quick tip for the meal preppers!
Pork tenderloin is an excellent option for those limiting fat intake on the keto diet; it’s super lean but still, packed with flavor. Since most keto pork recipes use fattier cuts, I wanted to be sure to post something for the folks that like (or need) leaner meat.
The Low Carb Pork Tenderloin Recipe
This low carb pork tenderloin recipe was a lot of fun! Believe it or not, my partner and I tag teamed this from conception to cooking to bring you the best pork tenderloin recipe we could mastermind.
It’s so bizarre because he ordinarily doesn’t like to cook or take an interest in developing recipes, but get him in front of a smoker or grill? GAME. ON. He gets so stoked. But honestly, who doesn’t love a good keto pork recipe?
I genuinely enjoyed sharing the cooking process with him, and I’m fairly confident he had fun too, so I’m hoping I can rope him into more collaborations! Fingers crossed! ?
The pork tenderloin is lean, but it typically comes with some pieces of fat and tough silverskin (aka fascia for the anatomy-minded folks) to remove. Cut off the fat and silverskin layers that encase the muscle before applying any rub.
We liberally coated the pork with yellow mustard before applying the dry rub; this prevents the dry rub seasonings to bind to the meat better instead of just melting off during smoking. Nothing fancy, just yellow mustard.
The dry rub is the same mixture we used for our smoked keto chicken wings recipe!
The dry rub:
1 tablespoon each: salt, pepper, garlic powder, chili powder
1 teaspoon each: dried oregano, dried parsley
Once you’ve applied the rub, wrap the entire pork tenderloin in plastic wrap and refrigerate for at least a couple of hours. If you have the time, you can let the pork sit in the fridge overnight.
Remove tenderloin from the fridge and allow the meat to come to room temperature. Just let it hang out on your counter for about 30 minutes. While that’s happening, go ahead and get your smoker ready. Using the wood of your choice (we used hickory), set the temperature up to 200 degrees Fahrenheit.
Get a pan piping hot, remove the plastic wrap, and quickly sear each side. It’s not a sear to cook the meat through, just a quick once-over to lock in the flavors.
Now bring your low carb pork tenderloin out to your smoker! Smoke until the internal temperature reaches 145 degrees Fahrenheit for medium rare or 160 for medium. This recipe took us about 2 hours, just keep your eye on the temperature to ensure the correct timing with your smoker… they’re all a little different!
Once you’ve hit your desired temp, remove it from the heat and give it time to rest. Don’t even think about cutting into it yet. You’ve got to let the meat rest a good 10 to 15 minutes before slicing!
You can enjoy your smoked pork tenderloin thinly sliced or in substantial, meaty cuts. Pair it with a low carb sauce, dressing, or as-is. This lean protein goes excellent with an easy vegetable side dish but can easily stand alone as a meal. After all, this is the best pork tenderloin recipe ever. #notsohumblebrag
