Air Fryer Pork Tenderloin
If you’re looking for a quick and easy dinner, the air fryer is an excellent choice. One of the biggest questions people ask is what temperature to cook tenderloin of pork in an air fryer. The answer is the same regardless of the cooking method—the internal temperature should reach 145°F (63°C) before resting.
Preheat your air fryer to 400°F and lightly coat the pork tenderloin with oil and your favorite seasonings.
Cook for 18 to 22 minutes, flipping the tenderloin halfway through the cooking process. Since air fryer models vary, begin checking the internal temperature after about 16 minutes.
Once the thermometer reads 145°F, remove the pork and let it rest for at least five minutes before slicing.
Slow Cooker Pork Tenderloin
Although pork tenderloin is a lean cut, it can be cooked in a slow cooker if you’re careful not to overcook it.
Place the seasoned tenderloin in the slow cooker with about one cup of chicken broth, apple juice, or your favorite cooking liquid.
Cook on:
- Low: 2½–3 hours
- High: 1½–2 hours
Use a digital thermometer to verify the internal temperature has reached 145°F.
If you’ve ever wondered what temperature to cook tenderloin of pork in a slow cooker, remember that the cooking appliance doesn’t change the target internal temperature.
Sous Vide Pork Tenderloin
Sous vide is one of the best ways to cook pork tenderloin because it delivers consistent results.
Set your sous vide machine to 140–145°F, depending on your preferred texture.
Cook for 1½ to 3 hours before removing the pork from the bag and quickly searing it in a hot skillet for about one minute per side.
The result is an incredibly juicy, tender pork tenderloin with a flavorful crust.
Common Mistakes to Avoid
Even experienced cooks occasionally make mistakes. Here are the most common ones.
Not Using a Meat Thermometer
Guessing doneness almost always leads to overcooked pork.
Always use a digital instant-read thermometer to know exactly what temperature to cook tenderloin of pork before removing it from the heat.
Cooking Too Long
Pork tenderloin cooks surprisingly fast.
Adding just five extra minutes can dry it out.
Monitor the temperature closely during the final few minutes of cooking.
Skipping the Rest Period
Resting isn’t optional.
Allowing the pork to rest for five minutes keeps the juices inside the meat instead of running onto the cutting board.
Forgetting to Remove the Silver Skin
The silver skin is a tough membrane that doesn’t become tender during cooking.
Removing it before seasoning improves both texture and appearance.
Using High Heat the Entire Time
High heat is excellent for browning but can overcook the interior.
For the best results, sear first and then finish cooking in the oven until the internal temperature reaches 145°F.
Best Side Dishes for Pork Tenderloin
Pork tenderloin pairs well with many classic side dishes.
Some delicious options include:
- Garlic mashed potatoes
- Roasted asparagus
- Honey-glazed carrots
- Roasted Brussels sprouts
- Green beans with almonds
- Wild rice
- Baked sweet potatoes
- Macaroni and cheese
- Caesar salad
- Roasted broccoli
Adding a flavorful sauce like apple cider glaze, Dijon cream sauce, mushroom gravy, or garlic herb butter can also elevate the meal.
How to Store Leftover Pork Tenderloin
Store leftover pork in an airtight container within two hours of cooking.
It will keep in the refrigerator for 3 to 4 days.
For longer storage, wrap the slices tightly and freeze them for up to three months.
When reheating, use low heat and add a splash of broth or water to help prevent the meat from drying out.
Frequently Asked Questions
Is Pork Tenderloin Safe if It’s Slightly Pink?
Yes.
As long as the internal temperature reaches 145°F, a slight blush of pink in the center is completely normal and considered safe to eat.
What Temperature to Cook Tenderloin of Pork for the Best Results?
The best answer is 145°F (63°C), followed by a three to five-minute rest.
This temperature provides the perfect balance of food safety, tenderness, and juiciness.
Can I Cook Pork Tenderloin to 160°F?
You can, but it’s generally not recommended.

Leaving the pork uncovered allows the exterior to brown properly while developing a flavorful crust.
How Do I Know When Pork Tenderloin Is Done?
