Hey Fantabulosity readers! It’s Meg again checking in with a ridiculously delicious and easy roasted pork tenderloin.

Roasted Pork Tenderloin

I’m betting you have all the ingredients for this pork tenderloin (except for maybe the pork) in your pantry and refrigerator already.

This roasted pork starts with a sliced onion on the bottom of your pan.

This provides a delicious little rack for the pork so it doesn’t sit in the juices while it roasts, adds some flavor, and gives a yummy little accompaniment to the pork when it’s finished.

How to Season Pork Tenderloin

Next the dry pork loin is rubbed with softened butter and sprinkled with a mixture of herbs and spices.

You’ll need kosher salt, pepper, dried thyme, dried basil, garlic powder, and onion powder. All pretty standard spices that combine to create the tastiest herby crust for the pork tenderloin.

Butter and Basting

Because the pork is rubbed with butter before baking, the flavor that is yielded is crazy rich and delicious. As the butter melts it bastes the pork and mingles with all the spices to create so much goodness.

Pork Tenderloin Ready-Made Sauce

The butter combines with the pork juices and creates a little pan sauce all on its own that is amazing drizzled over the sliced pork tenderloin. I promise you will be dragging your pork through ever last drop of it.

How long to cook pork tenderloin in the oven

This pork tenderloin only takes about 35 minutes to roast in the oven at 400°.

Pork Tenderloin Temp

I don’t know about you all but pork was a meat I always used to struggle cooking. It was either underdone or cooked so long it resembled jerky when chewing it. I just couldn’t seem to find the sweet spot when it came to pork.

What changed things for me? A digital meat thermometer with a temperature alert feature. You set the temperature you would like your food to be cooked, insert the probe, and put it in the oven (or grill or slow cooker). It’s oven safe and an alert will go off when the desired temperature has been reached.

I’m telling you, the thermometer is a complete game-changer. Especially when it comes to pork.

The safe temperature to cook pork to is now 145 degrees F so I set it that temperature then let it rest for 10 minutes after removing it from the oven.

Letting the pork rest, allows the pork to redistribute the juices and will keep it juicy rather than everything running out when you slice it.

TIP: The pork will also continue to cook in those 10 minutes so you could even set your thermometer to 140 degrees F instead if you want it cooked right to 145 degrees.

For me, I like it a little more just because even though I know it’s safe, the pink still freaks me out a little.

You can tell by looking at this gorgeously roasted pork tenderloin that it’s fancy enough to make for special dinner guests but you can also easily whip it up for your family on a Wednesday night too.

Slow Cooker or Crock Pot Pork Tenderloin Option

Although this pork is rich and juicy when roasted in the oven, it’s also a great option for the slow cooker. I tested it both ways and they yielded in amazing flavor and buttery goodness.

So, if you need to be away from your oven, prepare the pork tenderloin exactly as stated in the instructions, just placing in the slow cooker instead of a roasting pan. Cook on high for 4 hours and dinner will be ready to go.
