Reverse Sear Sirloin Cap (with Chimichurri)

Jump to Recipe

Sirloin cap (also called culotte, coulotte, or picanha) is a tender, versatile, and slightly lesser-known cut of beef. It's a great candidate for our easy reverse sear method, which you can do in the oven or on the grill. Don't miss it.

Why we love this recipe

Reverse searing is SUCH a genius technique. (Our reverse sear pork chops have gotten super-popular, in case you're into that sort of thing.) You cook the meat in a low oven or grill until it's almost done and then sear the bejeezus out of it briefly to finish. This results in perfectly cooked, tender meat with a gorgeous golden-brown crust.

This fabulous cut of beef is:

Super-flavorful (known for its bold, beefy flavor)
A very tender cut
Amenable to a wide variety of marinades and sauces, but also great on its own
Quick-cooking
Great by itself or sliced for sandwiches and salads
Among the most prized cuts of beef in Brazil, where it's called picahna and used for churrasco

Ingredients

Here's what you'll need to make a great reverse sear sirloin cap. Psst...it ain't much!

Sirloin cap (a.k.a. culotte // coulotte // picanha — so ask for any of those at the butcher) can weigh in anywhere between about a pound and two and a half pounds. Buy one or two, depending on size, to serve four to six people. It has a fat cap on one side, which is great for searing. This cut is fabulously tender and is known for its hearty beefy flavor.

Our favorite sources for meat

For years, I've been sourcing our meat from ButcherBox. We love this curated meat delivery service, which provides grass-finished beef, heritage breed pork, organic chicken, and more from small farms direct to the customer. You can learn more in my extensive Butcher Box review and unboxing.

More recently, we've also become big fans of Cooks Venture for chicken.

How to make it

Reverse searing this cut of beef really couldn't be easier. This cut is so tender — and the method is so controllable — that you can relax and enjoy even if you're not super-experienced cooking meat.

Here's an overview of what you'll do. You can see all the steps in action in the video that accompanies this post.

First you'll slice a crosshatch pattern into the fat cap. Cut just deep enough to go all the way through the fat, without slicing into the meat. Leaving the fat on helps the meat stay tender. Crosshatching lets the fat cook up crispy without changing the shape of the meat.
Roast the meat in a low oven (250°F / 121°C) or grill it over low, indirect heat.
Then get the pan blazing hot and sear it until golden-brown and cooked to your desired final temperature (or grill briefly over direct heat).
Resting is important to let all the gorgeous juices reabsorb into the meat. Let it sit for 10 minutes, and then slice against the grain.

Why reverse searing works

This cooking method, which works best for thicker cuts of meat, has several advantages. Compared to traditional roasting or grilling, it gives you:

More even cooking throughout the steak or roast, thanks to the lower oven temperature and longer timeframe
More tender results, because the meat spends more time in the temperature zone where enzymatic activity helps break down tough muscle fibers
Better browning, because the low and slow stint in the oven creates a thin, dry layer on the surface that takes well to searing

Expert tips and FAQs

Is sirloin cap tender?

It really is! This is a GREAT cut of meat. It's tender and super-flavorful on its own but also works well with whatever marinade, rub, and/or sauce you like.

Is top sirloin the same as sirloin cap?

It's not, exactly. The cap is the triangle-shaped part at the top of the top sirloin, which is a larger cut that sometimes includes the cap and sometimes is sold "capless." You can see the distinction easily in this great butchering video.

Where can I get one?

North American butchers tend to divide the cap and include it in other cuts, so you won't often find it in the grocery store. We get ours from Butcher Box, and you can ask for one at the butcher, too.

What does it mean to cut steak against the grain?

Beef has visible muscle fibers that run in one direction. You can see them before and after cooking. To cut against the grain, which results in more tender slices, you want to cut across those muscle fibers rather than parallel to them.

Final internal temperature

As with all beef, the final temperature of your sirloin cap should be:

120° to 125ºF / 49° to 52ºC for medium-rare
130°F / 50ºC for medium

A note on timing

In the oven

Depending on the size of your sirloin cap and the performance of your oven, it may take longer than the designated time to come up to 105°F (or 115°F for a medium- to medium-well final result). A common mistake is to turn up the oven at this point. Just be patient and leave it in at the prescribed temperature until it reaches 105°F.

On the stovetop

The timing of the final sear will also affect the final temperature. Start by searing the side with the fat cap for several minutes, until nicely browned and rendered. Then flip and sear the other side until the meat reaches your desired final temperature.

How to serve it

This is a super-versatile cut that's great sliced with or without sauce (like the chimichurri pictured here, or our popular cilantro sauce). It would be great in a sandwich or on a salad, or in tacos or burritos.

In the summer, try it with potato salad and/or esquites and a green salad.

In the winter, serve it over Yukon gold mashed potatoes or mashed cauliflower with smoked gouda.
