How to Trim Beef Tenderloin Roast:

If you see shiny "silver skin" on your beef tenderloin, you will want to trim that away as it is fibrous and chewy connective tissue that won't allow flavor to penetrate your tenderloin.

Slide tip of knife just under connective tissue
Keep knife tip close to surface of the meat to minimize meat loss
Use your other hand to pull connective tissue tight against the blade
Slide the knife angled away from the meat until it exits

*Also trim away excess fat from tenderloin – unlike most steaks, fat is unnecessary on beef tenderloin.

How to Tie a Beef Tenderloin:

Tying a tenderloin is important for even cooking. It makes the thickness more uniform and if you have a thin end on one side, you can tuck it under the tenderloin and tie to secure it in place, otherwise one end will be raw and the other over-cooked. A butcher can do this for you.Watch the video recipe for a full demonstration.

Use a kitchen string to loop around one of the tenderloin and tie a snug knot
Loop the string around your left hand and pull that loop over your tenderloin
Repeat the loops, spacing 1-inch apart and tightening each one snugly
Tie off the end with a knot after 5-6 loops

2 lb beef tenderloin , trimmed and tied
2 Tbsp unsalted butter, room temperature
1 Tbsp prepared Horseradish, strained
2 garlic cloves
1 Tbsp fresh rosemary leaves
1/2 Tbsp fresh thyme leaves
1 1/2 tsp salt
1 tsp black pepper

Remove tenderloin from refrigerator 1 hour before roasting. Trim and tie beef tenderloin. Preheat Oven to 500˚F with a rack in center.
Coarsely chop 2 garlic cloves then strip 1/2 Tbsp of fresh thyme leaves and 1 Tbsp of fresh rosemary. Finely mince together the garlic and herbs. Transfer them to a small mixing bowl. Add 2 Tbsp butter, 1 Tbsp horseradish, 1 1/2 tsp salt and 1 tsp black pepper. Use a fork and mash to combine.
Pat tenderloin dry with paper towel and spread the garlic herb rub evenly all over the tenderloin and transfer to a roasting pan or oven safe skillet. Insert an oven-safe meat thermometer into the thickest portion of your tenderloin and roast in a preheated oven at 500˚F for 28-30 min for medium doneness (140-145˚F).
Remove from oven and transfer to cutting board, tent loosely with foil and rest 10 minutes. Slice into 1/2" thick slices, and serve right away.

30-32 min for medium-well doneness (140-145˚F) - USDA recommends 145˚F.
33-35 min for well done (150˚F) - don't do this to your meat

*Timings can vary depending on your oven and the thickness of your tenderloin, so always check for desired doneness using an oven-safe meat thermometer.

Years ago, my husband and I stopped going out for Valentines Day after a bad restaurant experience (the busiest and worst day to go out to eat in my experience), and we've enjoyed our date-nights-in ever since! Are you going out or cooking in for Valentines Day? I'd love to know what you're cooking up!
