How Long to Cook Pork Tenderloin in Oven at 400?

How long should I cook my pork tenderloin? The answer to this question varies depending on how done you like your food, and the thickness of the meat. A good rule-of-thumb is 20 minutes at 400° F but it can range anywhere between 15 – 25 minute durations if cooked more towards rare (or less) degrees Fahrenheit.

For example, a 1-pound pork tenderloin that is about 1 to 1½ inches in thickness should be cooked for approximately 20 minutes at 400° F. If you like your pork on the rare side, cook it for 15 minutes. And if you prefer it more well done, cook it for 25 minutes.

It’s always best to use a meat thermometer to check the internal temperature of the pork before removing it from the oven. The safe minimum internal temperature for pork is 145° F. But we recommend cooking it to an internal temperature of 160° F for medium doneness.

Once the pork reaches the desired level of doneness, remove it from the oven and let it rest for 3 to 5 minutes before slicing and serving. This will allow the juices to redistribute throughout the meat, resulting in a juicier and more flavorful dish.

Now that you know how long to cook pork tenderloin in oven at 400, let’s go over the steps for how to do it. This recipe is simple and straightforward, and only requires a few minutes of prep time.

The first step in preparing your pork tenderloin is to cut off any excess fat and trim it dry with a paper towel. Next, heat up an oven preheated at 400 degrees Fahrenheit for 10 minutes before placing both skinless meat pieces as well as those that have their own layer of silverskin into the dish you’ve prepared ahead of time so they can be cooked through properly while still staying moist on top due do refrigerate afterward!

The spices and brown sugar blend together to create an amazing tangy aroma that will make your mouth water. After you rub oil over the pork, put all of these ingredients into one bowl for easy mixing! Covering every inch with spice seems like a must when cooking this dish because it’s not only delicious but also aesthetically pleasing as well.

The pork should be cooked through in 20 minutes, but if you want an extra firm roast then I recommend cooking it for 2-5 more minutes. When do check the internal temperature of your meat with an instant-read thermometer; don’t forget about placing this tasty treat under hot running water before putting it into the oven as well! This will help the outside cook evenly while keeping juices trapped on the inside.

After the pork is cooked through, let it rest for 3-5 minutes before slicing and serving. The resting time is important because it allows the juices to redistribute throughout the meat, resulting in a juicier and more flavorful dish.

Recipe Tips

Covering the baking dish with aluminum foil can lead to undercooked or rare pork. 

The best way is to use a meat thermometer for checking its internal temperature so it will be juicy and tender, but if you don’t have one of these measuring tools available then make sure not to cook your meal too long because this lean cut gets dry quickly when exposed directly on the flame without any kind protection like oven gloves!

When slicing, keep in mind that thicker =/= better here. If pieces are too thick they will be difficult to chew and not as enjoyable to eat. Cut against the grain for more tender bites!

If you want an extra crispy outside without overcooking the inside, try searing your pork in a pan over medium-high heat before oven roasting. This will create a nice crust on the exterior of the meat while the interior stays juicy and moist. Just be sure not to overcook the pork when searing, as this can lead to a dry and tough final product.

If you want to make the most of your pork, don’t skip this step. Let it rest for 5 minutes before slicing and cooking will be a cinch! This technique works with pre-marinated or seasonable meat too—you can even add fresh herbs if desired like thyme and rosemary.

This way we get tender cuts every time because those flavors have been locked in by now; not only are they retaining their moisture but also adding flavor as well thanks largely due to these little bits being cooked at high heat first (and then some).

If you have any leftovers, they can be stored in an airtight container in the fridge for up to 3 days. Reheat in a 350-degree oven until heated through. Pork tenderloin is also freezer friendly and can be stored for up to 3 months.
