This Slow Cooker Beef Brisket is fall-apart tender and packed with flavor thanks to a rich sauce made with balsamic vinegar, brown sugar, garlic, and herbs. It’s perfect for holidays, family gatherings, or a cozy Sunday dinner—and your slow cooker does most of the work!
Pat the brisket dry with paper towels. Combine salt, pepper, paprika, onion powder, and garlic powder, then rub all over the brisket.
Heat olive oil in a large skillet over medium-high heat. Sear the brisket on both sides until golden brown, about 3-4 minutes per side. Transfer to the slow cooker.
In the same skillet, sauté the onion and garlic until fragrant, about 3 minutes.
Deglaze the pan with beef broth, scraping up any browned bits. Stir in balsamic vinegar or wine, brown sugar, tomato paste, and Worcestershire sauce. Simmer for 2 minutes.
Pour the sauce over the brisket in the slow cooker. Add bay leaves and thyme sprigs.
Cover and cook on low for 8-10 hours, or until brisket is fork-tender.
Remove brisket from slow cooker and let rest for 10 minutes before slicing against the grain.
Optional: Strain and reduce cooking juices or thicken with cornstarch slurry for a gravy. Serve brisket topped with sauce.
Notes
Make it sweeter: Add honey or maple syrup to the sauce.
Add heat: A dash of chipotle powder or red chili flakes works wonders.
Thicker sauce: Mix 1 tbsp cornstarch with 2 tbsp cold water and stir into juices, cook on high for 15-20 minutes.
Vegetable option: Add carrots or potatoes for a full one-pot meal.
