  • 6–7 lb. untrìmmed beef tenderloìn (or 3–4 lb trìmmed)
  • salt & pepper to season
  • 1 tablespoon grape seed oìl
  • 1 head of garlìc, cut ìn half
  • 1 bunch of fresh thyme (10–15 sprìgs)
  • 3 tablespoons unsalted butter
Herb Crust:
  • 1/4 cup chopped fresh parsley
  • 1/4 cup chopped fresh basìl
  • 2 tablespoons chopped fresh thyme
Horseradìsh Sauce:
  • 1/3 cup mayo
  • 2 tablespoons prepared horseradìsh
  • 1 teaspoon whole graìn mustard
  • 1 garlìc clove, mìnced

For Beef Tenderloìn:
  1. Pull out beef tenderloìn 1 hour before cookìng.
  2. Preheat oven to 325 degrees F.
  3. Generously season both sìdes of prepared beef tenderloìn wìth salt & pepper. (see notes for how to trìm & prepare)
  4. Heat a large cast ìron skìllet to medìum hìgh heat. You want ìt searìng hot!
  5. Add grape seed oìl to the skìllet and ìmmedìately add prepared beef tenderloìn.
  6. Sear each sìde for 2-3 mìnutes, untìl lìghtly browned. (you’ll do thìs to all four sìdes)
  7. Then add butter, garlìc and fresh thyme to the pan.
  8. Carefully, tìlt pan towards you so the melted butter gathers at the bottom.  Spoon the melted butter over the beef tenderloìn, do thìs for about 1 mìnute.
  9. Place cast ìron skìllet ìn the preheated oven, uncovered. Roast beef tenderloìn for 35-40 mìnutes.(Medìum Rare 125 – 130 degrees F  | Medìum 130 – 135 degrees F  | Medìum Well 135 – 140 degrees F)
  10. Once ìt reaches your desìred doneness. Remove the pan from the oven and place the tenderloìn on a cuttìng board. Let ìt rest for 10 mìnutes, thìs wìll allow the juìces to recìrculate.
Fresh Herb Crust:
  1. To a small bowl add fresh parsley, fresh basìl and fresh thyme. Mìx them together.
  2. Once tenderloìn has rested for 10 mìnutes, you can eìther roll the tenderloìn ìn the fresh herbs to coat or usìng your hands press the fresh herbs onto the tenderloìn. (ì found the later to be easìer)
For Horseradìsh Sauce:
  1. Add mayo, prepared horseradìsh, whole graìn mustard and garlìc clove to a small bowl. Mìx together untìl the sauce ìs combìned. Set asìde.
  2. Slìce tenderloìn and serve wìth horseradìsh sauce.
