Garlic Brown Butter Roasted Beef Tenderloin

Ingredients

Ingredient notes & substitutions

Beef tenderloin:

Ask your butcher for a center-cut, trimmed tenderloin (sometimes called PSMO trimmed). Tying it ensures even thickness so it cooks uniformly edge to edge.

White pepper:

It adds a subtle, earthy heat that black pepper alone doesn't, and it's traditional on premium roasts. If you don't have it, just use extra black pepper.

Unsalted butter:

Unsalted lets you control the seasoning, and its milk solids are what toast into the nutty brown-butter flavor. Salted butter can brown unevenly.

Garlic:

Whole cloves gently perfume the butter without burning; you discard them at the end, leaving just their mellow, roasted essence in the sauce.

Salt:

Season generously and evenly — a large roast needs more than you'd think. Season right before searing so it doesn't draw out moisture.

Method

1. 1

   Preheat the oven to 450°F (230°C). Heat a heavy 12-inch skillet over medium-high heat.

2. 2

   Cut the tenderloin in half if needed to fit the skillet. For a thin, tapering end, fold it under and tie with kitchen twine to create an even thickness.

3. 3

   Season the beef generously all over with the salt, black pepper, and white pepper.

   
4. 4

   Sear the beef in the hot skillet on all four sides until deeply browned, about 3 to 4 minutes per side.

   
5. 5

   Transfer the seared beef to a roasting pan or 9x13-inch pan. Roast until the internal temperature reaches 120–125°F for medium-rare, about 30 minutes.

   
6. 6

   Remove from the oven and loosely tent with foil. Let the beef rest for 10 minutes (the temperature will climb a few more degrees as it rests).

   
7. 7

   While the beef rests, melt the butter in a small saucepan over medium heat. Add the garlic cloves and cook, stirring constantly, until the butter foams and turns a dark golden brown and nutty. Remove from the heat and discard the garlic.

   
8. 8

   Slice the tenderloin into 1/2 to 3/4-inch slices, drizzle with the garlic brown butter, and serve immediately.

   

Variations to try

• Stir a teaspoon of fresh chopped rosemary or thyme into the brown butter for a herby finish.
• Add a splash of balsamic or a squeeze of lemon to the brown butter to cut the richness.
• Make a horseradish cream sauce on the side for a classic holiday pairing.
• Crust the seasoned beef with a spoonful of Dijon before searing for extra flavor and a beautiful crust.

Storage & make-ahead

Store leftover sliced tenderloin in an airtight container in the fridge for up to 3 days. Because it's lean, it's best enjoyed cold (it makes incredible steak sandwiches or salads) or reheated very gently — a hot reheat will overcook the pink interior. To warm, cover and heat in a low 250°F oven just until barely warm, or dip slices briefly in warm gravy. The brown butter can be made ahead and gently rewarmed.

Frequently asked questions

What temperature is medium-rare beef tenderloin?

Pull it from the oven at 120–125°F; it will rise to about 130–135°F as it rests, which is a perfect medium-rare. For medium, aim to pull it around 130°F.

Why do I need to sear before roasting?

Searing builds a deeply browned, flavorful crust that roasting alone can't achieve. It's the difference between a good roast and a great one.

How much tenderloin per person?

Plan on about 6 to 8 ounces of raw weight per person. A 5 to 6 pound tenderloin comfortably serves 8, with a little extra.

Can I prep it ahead?

Yes — season and tie the roast up to a day ahead and keep it covered in the fridge. Let it come to room temperature before searing, and make the brown butter fresh while it rests.
