• 2 tbsp avocado oil
• 4 tbsp salted butter, softened
• 2 tsp garlic, minced
• 1 tsp horseradish (prepared or Dijon mustard)
• 1 tsp rosemary, minced (or substitute thyme)

Directions

1. Trim and tie the beef tenderloin if not pre-trimmed. Remove silverskin and excess fat, cut into two pieces, and tie with butcher’s twine to ensure even cooking.
2. Season all over with salt and pepper. Optional: Refrigerate overnight uncovered for a better crust.
3. On cooking day, bring to room temperature by letting the beef sit out for about 2 hours.
4. Preheat oven to 425°F.
5. Sear the beef in avocado oil in a large cast iron skillet over medium-high heat, about 3 to 5 minutes per side.
6. Mix butter topping: Combine softened butter with garlic, horseradish, and rosemary.
7. Slather the seared beef with the butter mixture, insert a probe thermometer, and transfer skillet (or place beef in an oven-safe dish) to oven.
8. Roast for 20 to 25 minutes until internal temperature reaches desired doneness:
   • Rare: 115°F to 120°F
   • Medium Rare: 120°F to 125°F
   • Medium: 130°F to 135°F
9. Rest the beef for 15 to 20 minutes before slicing into 1-inch thick pieces.

FAQs

What cut of meat is beef tenderloin?

Beef tenderloin is a lean, tender cut from the loin of the cow. It’s where filet mignon is sourced from.

Do I need to tie the beef tenderloin?

Yes, tying helps create a uniform shape for even cooking and a consistent texture.

Can I skip the overnight fridge step?

Yes, but refrigerating overnight uncovered helps develop a great sear and crust.

How long should I let it rest before slicing?

Let it rest for 15 to 20 minutes to allow the juices to redistribute properly.

What if I don’t have a probe thermometer?

You can use an instant-read thermometer, but probe thermometers ensure better accuracy.

Can I cook this ahead of time?

It’s best served fresh, but you can sear it ahead of time and roast just before serving.

What can I serve with this tenderloin?

Great side options include mashed potatoes, green beans, Brussels sprouts, or a creamy horseradish sauce.

Can I use olive oil instead of avocado oil?

Yes, but choose an oil with a high smoke point to avoid burning during searing.

Will the butter burn in the oven?

Not if applied after searing. It helps flavor the roast and creates a delicious crust.

What should the final texture be?

A properly cooked beef tenderloin should be juicy and melt-in-your-mouth tender.
