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

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!
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.

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 23 days until I’ll be serving it up again.
