Garlic Butter Pork Tenderloin

Baked pork tenderloin, seared to perfection, finished in the oven, and then topped off with a decadent garlic butter. Would you believe this recipe is ready in about 30 minutes?

I snagged a couple of pork tenderloins at the grocery store the other day. They were on sale and I’m all in for pork, so I couldn’t pass them up.

Of course, I had no idea what I was going to do with the pork tenderloin when I got it home, but I figured an idea would come to me.

It didn’t. That’s the way my brain works – I’m full of ideas until I need them. 😉

I asked Chad what he was feeling for dinner one night and he said he wanted something extra buttery and extra garlic-y, so I just went for it, you guys.

Garlic Butter Pork Tenderloin.

This looks and tastes like a fancy restaurant meal, but it was one of the easiest things I’ve made in a long time and it was ready in about 30 minutes.

How to make pork tenderloin:

First up, grab a heavy bottomed, oven safe skillet. I used cast iron.

Preheat the oven to 425 degrees.

This oven pork tenderloin starts off with a little Italian seasoning, salt, and pepper. Just sprinkle it all over on both sides.

Add some olive oil to your hot skillet. Once the oil is hot, sear the pork on both sides.

We’re locking in the juice and adding a ton of flavor by searing the meat before putting it in the oven. Don’t skip this step!

For baked pork tenderloin, we’re going to need to do a little oven time.

Pork tenderloin cooking time:

Pop the whole skillet into the hot oven and let it cook for about 15 minutes, depending on the level of doneness you prefer.

I like to cook my pork until it’s just oh so slightly pink in the center, so I pull it from the oven at 145 degrees and let it rest for about 5 minutes before cutting.

You can safely pull your pork anytime after 145 degrees and up to 160, if you like it well done. Just allow the pork tenderloin to rest for at least 5 minutes before slicing.

What to season pork tenderloin with:

Garlic butter, of course!

We’ve already started it out with a little Italian seasoning, salt, and pepper, but now we’re going big and bold.

Once your pork is cooked and rested, melt together a little butter, a lot of garlic, some onion powder, and fresh parsley.

Pour it right over the top of your tenderloin.

Can’t you just smell it when you look at the photos? So. Good.

What to serve with pork tenderloin:

There are so many delicious low carb side dishes that would work with this pork tenderloin!

My fried radishes are a great sub for potatoes and I think they work perfectly with this tenderloin recipe.

Keto coleslaw is always a win with any type of meat.

Brussels sprouts and bacon would make a lovely side dish and so would this cauliflower mac and cheese.

You could also keep it simple with a fresh green salad or some zoodles tossed in a little sugar-free marinara.
