Slow-Cooker Mushroom Dijon Cream Brisket Step-by-step instructions

Before you start

Before starting, pat the brisket dry with paper towels and trim any excess fat, leaving a thin layer. Halve the cremini mushrooms if they are large. Measure out all ingredients.

Have your slow cooker ready. There is no need to sear the beef; the video shows it goes straight into the pot. Prepare the rice just before serving, as it can stay warm in a covered pot.

Instructions

Layer and Season

1. 1Layer the Brisket
   Place the trimmed beef brisket flat in the bottom of a 6-quart slow cooker. Sprinkle the dry onion soup mix evenly over the top of the brisket. Scatter the halved cremini mushrooms around the sides of the brisket.
   Look for The brisket should fit snugly in the bottom of the slow cooker, with the mushrooms tucked around it.
   Tip Trim excess fat from the brisket, but leave a thin layer to keep the meat moist during the long cooking time.
2. 2Add the Creamy Toppings
   Dollop the sour cream over the top of the brisket and mushrooms. Spread the whole-grain Dijon mustard over the sour cream. Pour the beef au jus along the side of the slow cooker, avoiding the top of the brisket to keep the seasoning in place.
   Look for The brisket should be covered with a layer of sour cream and mustard, with the au jus pooling around the edges.
   Tip For a smoother gravy, whisk the sour cream and mustard together before adding, but the video shows them dolloped separately.

The brisket sits flat in the slow cooker, covered with a layer of onion soup mix and surrounded by halved mushrooms. Dollops of sour cream and smears of Dijon mustard create a creamy topping, and the au jus pools around the edges. The scene looks rustic and inviting, with contrasting colors of white, yellow, and brown against the black pot.

Slow Cook to Tender

3. 3Slow-Cook Low and Long
   Cover the slow cooker and cook on LOW for 8 to 10 hours, or on HIGH for 4 to 5 hours, until the brisket is fork-tender and easily shreds. Do not lift the lid during cooking to maintain even heat. Let it rest for 3 minutes before slicing.
   Look for The brisket should be very tender and the sauce bubbling gently around the edges.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip For the most tender results, always use the LOW setting if time allows.
4. 4Check for Tenderness
   After the minimum cooking time, insert a fork into the thickest part of the brisket. The meat should shred easily with little resistance. If it is still tough, continue cooking for another 30 minutes and check again. Let it rest for 3 minutes before slicing.
   Look for The brisket should pull apart with a fork, and the gravy should be thick and creamy.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip If the gravy seems too thin, remove the brisket and simmer the sauce on the stovetop to reduce, but the video shows a thick sauce.

During cooking, the slow cooker emits a gentle bubbling sound and a rich, savory aroma. The brisket simmers in a fragrant broth, and the mushrooms soften. After 8 hours, the meat is deeply browned and the sauce has thickened. The brisket should be fork-tender, and the gravy should cling to a spoon. The kitchen smells of beef, onion, and tangy mustard.

Shred and Serve

5. 5Rest the Meat
   Once the brisket is fork-tender, remove it from the slow cooker and place it on a cutting board. Let it rest for at least 3 minutes before shredding or slicing. This allows the juices to redistribute.
   Look for The brisket should rest in its juices, and the sauce should settle.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip Resting is essential for a moist, flavorful brisket; don't skip it.
6. 6Shred and Serve
   Using two forks, shred the brisket into bite-sized pieces. Return the shredded meat to the slow cooker and stir gently to coat with the creamy mushroom gravy. Serve hot over steamed white rice, spooning extra gravy over the top. Let it rest for 3 minutes before slicing.
   Look for The brisket should be coated in the creamy Dijon sauce, with mushrooms and onions throughout.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip For a thicker gravy, mash some of the mushrooms into the sauce before adding the meat back.

The brisket is lifted out and rests before shredding, with steam rising from the tender meat. The shreds are moist and coated in a velvety, creamy sauce with visible bits of mustard and mushroom.

Plated over white rice, the dish looks hearty and comforting, with a glossy sheen from the sauce. The final dish is a beautiful presentation of creamy beef and mushrooms.

Common mistakes

Avoid lifting the lid during cooking, as this releases heat and extends cooking time. Do not add extra salt, as the onion soup mix is salty. Do not use low-fat sour cream, which may curdle during long cooking.

If the sauce is too thin, remove the meat and simmer the sauce on the stovetop to reduce. For the most tender results, always use LOW heat, even if it means a longer wait.

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 reach at least 145°F (63°C) for food safety, but the long cooking time will bring it well above that. The sauce should be thick and creamy, not watery. If the meat is still tough, cook for an additional 30 minutes and check again.

• Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
