Ingredients:

2.5 kg (5.5 lbs) beef brisket
1 tbsp olive oil
1 onion, sliced
4 garlic cloves, minced
1 cup (250ml) beef stock
1 cup (250ml) BBQ sauce
1/4 cup (60ml) apple cider vinegar
2 tbsp brown sugar
1 tbsp Worcestershire sauce
1 tsp smoked paprika
1 tsp dried thyme
Salt and pepper to taste

Instructions:

Heat olive oil in a large skillet over medium-high heat. Sear the brisket on all sides until browned. Transfer to the slow cooker.

In the same skillet, add onion and garlic, and cook until softened.

Pour beef stock, BBQ sauce, apple cider vinegar, brown sugar, Worcestershire sauce, smoked paprika, and thyme into the skillet. Stir to combine and bring to a simmer.

Pour the sauce mixture over the brisket in the slow cooker. Season with salt and pepper.

Cover and cook on low for 8-10 hours, or until the brisket is tender.

Remove the brisket from the slow cooker and let it rest for 10 minutes before slicing. Serve with the sauce.
