Pork Tenderloin




About: I work at instructables by day, and turn into a stitch witch by night. follow me on instagram @jessyratfink to see what i'm working on! ^_^

A pork tenderloin is such a versatile and amazing piece of meat to cook. You really only need a probe thermometer to get it perfect - it's really forgiving! And it accepts all kinds of flavors. I tend to always season my pork tenderloins in a more traditional way - mustard and herbs - but you can really go nuts. :D

Read on and let me walk you through how to make the most perfect pork tenderloin.

Step 1: Ingredients:

  • a pork tenderloin
  • olive oil
  • herbs & spices of choice
  • mustard or another sauce you're fond of
  • salt & pepper
You'll also need a roasting pan and a probe thermometer. (This is the probe thermometer I use - I've used it for years with no problems!

One tenderloin will serve four people.

Step 2: Apply Your Seasonings and Preheat

Preheat your oven to 400 F.

For a pork tenderloin, I like to use mustard to bind the spices to the meat. If you don't use mustard, oil works well!

For this one, I used a good amount of salt and pepper, several pinches of paprika, three of rosemary, and a pinch each of garlic and onion powder. The mustard is just a few teaspoons. 

This is really all up to you - but remember, it is better to over-season instead of under-season! There's a lot of meat in the middle that won't get direct seasoning.

Once you've added your spices and binder, rub the tenderloin all over. I like to pop it in the fridge for a little bit before cooking, but you can do it right away, too!

Step 3: Sear the Tenderloin

This is optional, but I think the flavors are better and it looks nicer in the end. :D Heat a pan over medium high heat with a little oil in it, and quickly sear all sides of the tenderloin.

Once it's seared, put it on a lightly oiled baking sheet or pan.

Step 4: Cooking + Resting

Insert a probe thermometer the middle of the thickest part of the pork. You'll be cooking your tenderloin in a 400 F oven for 15-20 minutes.

You want your tenderloin to reach 140 F. At that point, pull it out of the oven and put it on a plate to rest. I like to rest it for 5-10 minutes.

NOTE: Cooking it to 140 F will result in slightly pink pork. This is safe and fine! If it really bothers you, take it to 145-150 F and then pull out and rest.

Step 5: Slice and Serve!

Slice it thinly and serve! I made some caramelized onions to go with it for dinner. :D

    My wife and I have been cooking this delicious piece of meat for 25 years!! You've done a great job of showing it to others! We sprinkle ours with olive oil then a bit of Cajun spice, Montreal steak spice and Greek spice, on the top rack of the preheated barbee on medium, 14 minutes per side for a total of 28 minutes. My mouth is watering!! So good!!

    Could you please inform me of your proper legal name and address so my attorney can file suit against you? I have put on many pounds of weight due to your addictive incredibly delicious recipes. I once looked forward to a major league baseball career but now find myself looking forward only to dinner. Consider this your notice that I shall be going to my lawyer's office right after picking up a pork loin for tonight's dinner.

    Way to go, Looks as well as it cooks.
    Just someone had a Recipe for Smoked Tenderloin.
    I use to get down in El Campo, Texas, Where a gas station, smoke-house combo, sold the Best Tenderloin I ever had!

    Ha! I wanted to make it for you on your last day, but of course the grocery nearby didn't have tenderloin. But I hope the fried porkchops were just as good. :D
