Slow Cooker Brisket

The easiest and best slow cooker recipes are the ones that don’t involve any stovetop cooking, like this rich and tender slow cooker brisket flavored with onion soup mix. Perfectly tender and extremely flavorful with just a touch of sweetness, it’s a hearty comfort food main course that’s worthy of your Sunday supper or holiday dinner menu—whether it’s Easter or Christmas.


1 1 oz. envelope onion soup mix
1 tbsp. light brown sugar
1 1/2 tsp. kosher salt
1/2 tsp. ground black pepper
1 3 lb piece of beef brisket (flat cut)
8 fresh thyme sprigs
8 whole garlic cloves
2 bay leaves
1 lb. carrots, peeled and cut into 2-inch pieces
1 lb. golden baby potatoes
3 celery stalks, cut into 1″ pieces
1 large sweet onion, cut into 8 wedges
2 1/2 c. beef stock
2 tbsp. Worcestershire sauce
2 tbsp. cornstarch


  1. In a small bowl, combine the soup mix, sugar, salt, and pepper. Sprinkle the mixture over both sides of the brisket and rub it into the meat.
  2. Place the meat, fat cap side down, into a 6 to 8-quart slow cooker. Place the thyme sprigs, garlic, and bay leaves on top of brisket. Add the carrots, potatoes, celery, and onion over top.
  3. In a liquid measuring cup, whisk together the stock, Worchestershire sauce and cornstarch until the cornstarch is fully dissolved. Pour the liquid into the slow cooker. Cover and cook on high for 5-6 hours, or low for 8 hours until the brisket is tender to slice, but not falling apart.
  4. Remove the brisket from the slow cooker and transfer to a cutting board, fat cap side up. Remove and discard the thyme sprigs and bay leaves. Thinly slice the brisket against the grain. Serve alongside the vegetables, drizzled all over with the gravy from the slow cooker.
