Hey friends, do you have a “all or nothing” mentality when it comes to hosting? Like, you either go big, or your don’t do it at all? I say STOP. Lose that mindset, and start thinking in a new way.

Years ago, we were invited to another family’s home, and I’ll never forget the feeling. It was a sense of “relief.” As in, I could do this, too. I don’t remember the exact recipe, but it was a pork loin. So today I’m sharing a recipe we’ve enjoyed in our kitchen for years, Roasted Rosemary Pork Tenderloin Recipe.

Are pork loin and pork tenderloin the same thing?

I have readers ask me, what is the difference between a pork loin and tenderloin?

The difference is that a pork loin is wide enough that you can cut steak-like pieces from it (you see these in a pack in the grocery stores). A pork tenderloin is a thin and small loin, which doesn’t have to be cooked long at all.

How to make pork tenderloin

  1. Prepare the pork according to my directions the day before; use a lot of fresh rosemary!
  2. Wrap in plastic wrap and store in the fridge overnight.
  3. Sear tenderloin on all sides until nicely colored all over.
  4. Transfer the pan to the oven and roast for 15 minutes.
  5. Let the pork rest before thinly slicing; get the rest of the food on the table.

Pork tenderloin is delicous paired with these Roasted Lemon Thyme Balsamic Marble Potatoes, or for quick and easy, we had it for dinner last week with ramen noodles.

How long do you cook pork tenderloin in the oven?

Heat oven to 375 degrees. Cook the pork for 10-15 minutes, until internal temperature reaches 145 degrees.

The secret is to let the pork loin rest for 5-10 minutes before slicing. Also to not over cook the loins.

Pork is perfect and safe at 145 degrees. It used to be 165, but they changed the recommended temp a few years back!

Back to the happy hostess!

The hostess was doing last minute things when we arrived, but she was very engaged with our family. She was naturally preparing for the meal, but we were her priority.

The table wasn’t set yet, but the dishes were out. She didn’t seem to be overly concerned at the state of her home. It was clean, but not really picked up.

But guess what? Her family was so happy, little kids buzzing around, music playing, a beautiful bunch of fresh flowers on the still-wet, wiped down counter.

She was happy!

Oh, and guess what dessert was? The dessert was a store-bought cake, but she dressed it up with whipped cream and fresh berries. Perfect.

Our friend made hosting look so easy, it inspired me.

I went home, called a few friends, and got a date on the calendar to replicate what I learned from her.

Hosting is beautiful when we let expectations and the silly little things that haunt us (like things have to be perfect) GO!
