Welcome to first full week of December…and happy Monday! 

Just in case you aren’t already completely aware of this fact…it’s the most festive month of the year! The time of year when dinner parties are in full swing, and fancy menus items, like this Roasted Beef Tenderloin are just what everyone needs in their back pocket. Easy recipe ✔️ Delicious recipe ✔️ YES!

You guys, I’m sorry if all my Christmas talk is making you want to pull your hair out, but I literally just can’t help it. I think the crazy year I’ve had just has me so overjoyed for this month. I LOVE the month of December with all of its excitement. I also love how by the end of the month, things finally start to settle down and pretty much the whole world takes a chill pill, which is kind of needed for me at the moment. The year has been go, go, go for me, and I’ve loved every minute, but I have to say, I’m excited for Christmas Eve with my family. It’s a low-key night full of cooking, good food, plenty of cocktails for some, gift wrapping and hanging out by the fireplace. I mean, it’s still a crazy day, but in good way, that I 100% love. In fact Christmas Eve is probably my favorite day of the entire year. It’s probably the one day of the year that I don’t think about work. I just cook a good meal, listen to Christmas music and hang out with my family…and whomever is currently sharing my parents house…you just never know who’s gonna be there!

I wanted to kick off the month with my family’s Christmas Eve Dinner entree. Last year I did a standing rib roast, but this year I’m going back to the classic Gerard family meal of Christmas Eve roasted beef tenderloin.

I know it’s only the beginning of December, but I thought you planners of the world might appreciate me being on the ball this year. Plus, the entire month is dedicated to holiday eats, drinks, appetizers and a few easy dinners for busy nights. Are you excited yet? Because I am so excited…as if that wasn’t obvious before.

My family moved to Colorado when I was in 8th grade, but before that, every year my parents would host my dad’s side of the family for a Christmas Eve party. I want to say there were around twenty-five to thirty people, so our house was pretty packed. My mom always prepared the same meal ever year. Yup, a roasted beef tenderloin. My mom is a huge lover of good beef, but this cut right here is her favorite. Plus, I’m pretty sure my grandma (Dad’s mom) would serve it on Christmas Eve, before my mom started hosting the family gatherings, so really my mom was just carrying on the tradition.

Anyway, mom made beef tenderloin ever year, and when we moved, she continued to do so. When I started cooking however, I kind of wanted to get creative with the big dinner. I’ve cooked up a few different roasts over the last couple of years, always some kind of beef, but I’ve yet to try my hand at a beef tenderloin.

Well, that just changed, and to be completely honest, I may never have the urge to get creative again. Something about this meal is just so amazing. I mean, for one, it’s as easy as can be. I’m talking EASY, one skillet and ready in less than an hour. Seriously.

Two, it’s possibly one of the most delicious meals for anyone who eats meat, my family absolutely LOVES beef tenderloin and considers it a very special treat. I’m talking melt in your mouth kind of delicious treat.

The beef is seasoned simply with crushed peppercorn, kosher salt and Dijon mustard. If you don’t like mustard, don’t let that scare you off. It adds flavor, but in a subtle way. You’d never guess the mustard was there, but trust me, you need it.

The secret though? Just a little bit of butter…I can see my cousin rolling her eyes now, “more butter!?”. Yes Abby, more butter, but only a couple of tablespoons, and honestly, it really is the secret here. It’s what makes the meat just melt in your mouth and helps to make it tender, juicy and perfect.

I roasted the beef over a bed of mushrooms for yet another layer of flavor. The mushroom and pan drippings are what create the white wine cream sauce. Here’s the thing, while the steak is amazing on its own, this sauce takes it to a whole different level. The drippings from the pan create the most flavorful cream sauce and it’s probably the best thing ever when paired with beef tenderloin, for real.

So is your mouth-watering yet? Because I know any family member of mine who may be reading this is going to be kicking themselves that they weren’t around to eat this one. Don’t worry, Christmas Eve guys, Christmas Eve! Only nineteen days until I’ll be serving it up again.

Hoping this Gerard family favorite will now be on your family’s menu too!
