Though, I’ll be honest, for most of my life, Christmas dinner has been…pizza. It’s a tradition at this point! My brother and I were competitive swimmers when we were younger, which meant we still had swim practice on Christmas Eve.

So, with the both of us swimming from early afternoon to almost eight o’clock at night, my mom needed a fast and easy dinner to get on the table…which is how pizza became our go-to on Christmas Eve (my personal favorite is our margherita pizza)!

But, before all of that, my mom used to make HUGE Christmas dinners. I mean, we used to have a house full of family. So, lots of food that was easy to make was a necessity.

Which is how my mom came up with this recipe!

Rosemary and garlic are a classic combo. It’s something almost everyone loves! Though, the addition of orange zest not only adds a depth of flavor, but it adds a bright pop to this tenderloin without adding sweetness or being distracting.

The simplicity of this recipe will not only make it a must-have for every holiday, but it also allows for every side dish you decide to make taste incredible alongside it!
