Honestly, we’re gonna be treating this rosemary garlic butter beef tenderloin VERY similar to how we would cook a regular ‘ol steak dinner. It’s just a little bit bigger, no sweat.
- Salt ‘n’ pepper your tenderloin and then we will ATTEMPT to sear this bad boy in a cast iron the best we can. If it’s too big to fit, just keep turning it in batches to make sure every inch gets a nice sear.
- Then, we’re gonna employ rosemary garlic butter to get smothered into EVERY inch of the tenderloin and then let the oven take care of business.
- Couple things for roasting this tenderloin: We’re going to do a HIGH temp of 400F and because of this high temp, it will only take a good 20-25 minutes for the tenderloin to reach an internal temp of 120-125 which should be a beautiful medium rare cook. (for those of you who like your meat more on the done side, no worries! There will be plenty of slices near the outside that will be less rare)
- SAUCE. Nice and simple red wine reduction sauce that quite frankly, takes this garlic butter roast beef tenderloin TO THE NEXT LEVEL.
Seriouslyyy. This beef is just going to melt in your mouth it’s so freaking tender and juicy.
Just don’t confess to your dinner guests that this tenderloin was about the easiest thing you’ve ever made in your life.
