Doesn’t that look cool? This is what the marinade ingredients looked like before stirring them up and adding the beef tenderloin. Later, Wayne told the boys we were eating meat cooked with mud and sticks and leaves. Do you think they believed him?

This recipe was one of two new ones we tried for our Christmas Eve dinner, and it tasted absolutely delicious. I really liked the Beef Wellington, and loved the “awe” factor of that recipe, but this one was the hands down favorite, and much easier to make besides. We’ll definitely be having it again in the future.

I had to purchase horseradish to make the recommended sauce, and I was a bit leery about that because from past experience it’s not something we like. However, the sauce turned out to have an understated horseradish taste and worked quite well with the beef. It also tasted pretty good on our baked potatoes!

Basically, make the marinade and let the beef sit in it for 1-24 hours (we did about 6), then roast it and serve with the sauce. We’ll give it a thumbs up for a perfect celebratory dinner.

  • 1/2 cup olive oil
