Nothing says Christmas dinner like a Rosemary Beef Tenderloin recipe!
I’ll let you in on a little secret.
I’m making Rosemary Beef Tenderloin for our Christmas Eve dinner and I’m already giddy with excitement. Every time I’ve made this dish there are ooohs and ahhhs followed by silence.
That’s the sound of people enjoying their food – silence.
It’s a good thing.
Now, you guys know I’m pretty darn practical.
While I don’t generally have fresh rosemary sprigs hanging out in my fridge, I say if it’s a special ocassion, then get yourself to the grocery store and buy you some.
Heck, you can use the extras to make your serving platter or plates look all fancy. Or tuck a sprig into your cloth napkins at each place setting – that’s super cute, too!
But in a pinch, dried rosemary will work, just decrease the amount by about half.
The best way to cook beef tenderloin
I remember the first time I cooked a really beautiful – and expensive – beef tenderloin cut of meat.
And yes, I do believe that a nice cut of beef can be beautiful
I was shaking in my boots, friends, because I saw what the price tag was on that bad boy.
Well, that, and I was cooking beef tenderloin for a crowd of 20 of my favorite people. At a 40th birthday celebration.
Trust me, I 100 percent did NOT want to be that person. You know, the one who ruins a perfectly good whole beef tenderloin.
So you know, no pressure, right????
If you’re feeling the same way, don’t fret. I’ve got you, friend!
Perfect Beef Tenderloin
Before we get started, before we even start talking about my holiday beef tenderloin, there is one tool that is imperative for this recipe.
My tip right here, it’s gonna make or break your beef tenderloin success.
You’ve gotta have a digital or instant read meat thermometer for this recipe.
If you don’t have one, hop on to Prime and get one. I’ll wait right here watching my free trial of Netflix….
But really, to make this the right way, you need a meat thermometer. .
Okay, now that we have that taken care of let’s get talkin’ beef.
How to make the best beef tenderloin recipe
When you buy at beef tenderloin at the store, it generally is tapered (thinner) at one end.
There are two ways to look at this.
If you leave it as is, you’ll have a piece of meat with one end that has cooked waaaaay faster than the entire rest of the beef tenderloin.
If we’re thinking glass half full, that may be just the thing for the relative at your holiday table who likes their meat well done, and then cooked some more.
Bless their heart.
But really, in my opinion it’s a downright crime to cook beef tenderloin to well done. Just – don’t.
My preference is to fold the thin end in on itself so it is just as thick as the rest of the tenderloin. Then use some butchers string to tie and hold it into place.
Yes, I should take a photo of that. Consider this the placeholder until Christmas. I’ll grab another photo.
You don’t need any fancy butcher/sailor’s knot here, the idea is just to hold that part together.
As much as it pains me to do this, here’s a great video from Martha Stewart showing you how. Skip to the :20 mark and you’ll see what I’m talking about.
This way, everything cooks evenly and there aren’t burnt ends on the end of your roast. Those are great in a pork recipe but this one, not so much.
How to Cook Beef Tenderloin
Preheat the oven to 350 degrees. Heat oil and cook your mushrooms and shallots, seasoning with salt and pepper.
This is one of the times I’m going to tell you to splurge for shallots. If you really don’t have them, or don’t want to buy them, I love keeping freeze dried shallots in my spice cabinet. Cook everything for a few minutes until they start to get a little color. Remove them from the skillet and set aside.
Make the garlic rosemary rub
In a small bowl, combine the remaining olive oil, rosemary and garlic. Add some fresh ground salt and pepper and make into a paste or rub. Rub the mixture all over the beef.
Get it oven ready
Place the sliced red onion on the bottom of the skillet. Put the seasoned beef tenderloin on top. Add the cooked mushrooms and shallots along the sides of the beef.
Cook it, baby!
Place the pan with all its loveliness in your pre-heated oven for 45-50 minutes for medium rare or longer for more well done results.
Remove from oven and rest for 10-15 minutes, tented by foil, before you cut the beef for serving.
When your roasted beef is done cooking, transfer to a cutting board and let it rest for about 10-15 minutes, tented with foil.
Then slice and serve alongside creamy make ahead mashed potatoes.
Make Ahead Beef Tenderloin
Okay, as I mentioned, I love to make this for Christmas Eve.
Here’s the catch. We tend to go to mass on Christmas Eve, too. So here’s my tips to prep beef tenderloin ahead of time!
The beef tenderloin can be seasoned and chilled up to two days in advance.
What to Serve with Beef Tenderloin
My favorite way to serve rosemary beef tenderloin is with a side of horseradish cream sauce.
Also, oven roasted potatoes, make ahead mashed potatoes and Roasted Balsamic Brussels Sprouts would be downright delicious sides.
And red wine. You’ve gotta serve red wine.
