Beef Filet Pretzel Sliders with Horseradish Sour Cream Sauce

The other night Bill and I made these beef filet pretzel sliders with horseradish sour cream sauce for dinner and my, oh my, were they good. The beef was so tender and the caramelized onions lent such a great flavor to the beef filets. I knew these were going to be good.


At first, while I was waiting for Bill to come home from work, I started prepping the horseradish cream sauce and the onions, until I cut my finger on our mandolin. Man, did that hurt. Needless to say, that slowed me down a bit as I was running around the house with gauze in my hands while yelling at the kids for some help. They looked at me like I was crazy. I managed to get myself bandaged up and the onions in the pan to saute, but as soon as Bill walked in the door, I handed him the knife and assigned him steak duty. Cooking with basically one hand just wasn’t working.


Once the steak was done, we let it rest for two minutes before assembling the sliders. The house smelled so good and Bill was starving. He couldn’t wait to dig in. As I sat down at the table, Bill took his first bite and was instantly a fan. These sliders are so simple to make and so, so, good. The horseradish sour cream sauce tops it off just perfectly too. They’re very filling. Definitely more than enough for an actual dinner.
