Grilled Horseradish Crusted Filet Mignon Steaks

Cooking filet steaks to a medium-rare temp guarantees a tender bite. To test your meat temp, use a thermometer. 135 is rare. 170 is well done.

Grilled Horseradish Crusted Filet Mignon Steaks

Grass-fed beef tastes slightly different from corn-fed beef. It tastes a little brighter and earthier. It’s preferred by those following the paleo diet. *Omit the sugar in this recipe if you’re eating paleo.

I always grill steaks on my Grill Grates. It elevates them from the heat and prevents flare-ups, plus it makes beautiful grill marks.
