Rosemary Thyme Butter Beef Brisket Step-by-step instructions

Before you start

Before you start, trim the brisket if needed and pat it dry with paper towels. Smash the garlic cloves with the flat side of a knife to release their flavor.

Rinse the fresh herbs and pat them dry. Measure the butter and have it ready. No need to sear the meat—the slow cooker does all the work. Make sure your slow cooker is clean and ready to go.

Instructions

Layer and Butter

1. 1Layer the Brisket
   Place the trimmed beef brisket flat into the bottom of the slow cooker. Scatter the smashed garlic cloves and fresh rosemary and thyme sprigs over the top of the roast, tucking a few underneath for even flavor.
   Look for The brisket should be in a single layer, with herbs and garlic covering the surface.
   Tip Trim excess fat but leave a thin layer for moisture.
2. 2Add the Butter
   Place the whole stick of salted butter on top of the seasoned roast. It will melt and baste the meat as it cooks.
   Look for The butter sits right on top of the herbs and garlic.
   Tip Cut the butter into a few pieces if you prefer it to melt faster.

At this point, the brisket sits in the slow cooker with garlic and herbs scattered on top, and the butter is melting over everything. You should see the butter begin to soften and pool around the meat. The aromatics are fragrant and the raw meat is seasoned. This is the 'dump it in' stage—nothing else to do but cover and cook.

Slow Cook and Shred

3. 3Slow-Cook the Brisket
   Cover the slow cooker and cook on low for 8 to 10 hours, until the brisket is fork-tender and easily shreds. Do not lift the lid during the first 6 hours to keep the heat steady. Let it rest for 3 minutes before slicing.
   Look for The meat is deeply browned, the garlic is soft, and the liquid is bubbling gently.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip Low and slow is the key to tender brisket; high heat will toughen it.
4. 4Rest and Shred
   Turn off the slow cooker. Transfer the brisket to a cutting board and let it rest for at least 3 minutes. Then shred the meat with two forks, discarding any large fat pieces. Return the shredded meat to the slow cooker and stir gently into the jus.
   Look for The meat pulls apart easily with no resistance.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip Resting allows the juices to redistribute, keeping the meat moist.

After 8 to 10 hours, the kitchen smells of buttery herbs and roasted garlic. The brisket is deeply browned, and the liquid is bubbling gently around the edges.

A fork slides in easily, and the meat pulls apart into tender shreds. The garlic cloves are soft and sweet, and the rosemary and thyme have infused the jus. The meat should rest before shredding.

Serve and Enjoy

5. 5Serve with Mashed Potatoes
   Spoon the shredded brisket and its buttery jus over whipped Yukon Gold mashed potatoes. Serve hot, with extra jus spooned over the top.
   Look for The meat is glossy with butter and herbs, and the jus pools around the potatoes.
   Tip For a low-carb option, serve over cauliflower mash or roasted vegetables.

The shredded brisket is glossy with butter and jus, and the herbs are visible throughout. Spooned over mashed potatoes, it looks like a comforting, hearty meal. The jus is golden and emulsified, with a rich, savory flavor. Taste a piece—it should be juicy, tender, and full of garlic-herb goodness. Serve hot, with extra jus on the side.

Common mistakes

One common mistake is lifting the lid too often to check on the meat. Each time you open the slow cooker, heat escapes and extends the cooking time. Trust the process and keep the lid on for at least the first 6 hours.

Another mistake is using a lean cut like round roast, which can dry out. Stick with brisket, chuck, or bottom round. Finally, don't skip the resting step—shredding too soon can make the meat dry and stringy.

How to tell it’s done

The brisket is done when it is fork-tender: a fork inserted into the thickest part should twist easily, and the meat should shred with little resistance.

The internal temperature should read at least 145°F (63°C) for food safety, but because it cooks low and slow, it will likely be well above that—often around 190°F (88°C)—which is ideal for breaking down collagen. Let the meat rest for at least 3 minutes before shredding to allow the juices to redistribute.
