Slow Cooker Brisket with Balsamic Onion Gravy is a tender, flavorful dish where beef brisket simmers all day in a tangy-sweet balsamic sauce with caramelized onions. It’s comforting, rich, and perfect for family dinners or special occasions.

Ingredients

  • 3–4 lb beef brisket
  • 2 large yellow onions, thinly sliced
  • 4 garlic cloves, minced
  • 1 cup beef broth
  • 1/4 cup balsamic vinegar
  • 2 tablespoons brown sugar
  • 1 tablespoon Worcestershire sauce
  • 1 tablespoon Dijon mustard
  • 1 tablespoon olive oil
  • Salt and pepper to taste
  • 1 tablespoon cornstarch (optional, for thickening)
  • 2 tablespoons cold water (for cornstarch slurry)

Instructions

  1. Season brisket generously with salt and pepper on both sides.
  2. Heat olive oil in a skillet over medium-high heat. Sear brisket 2–3 minutes per side until browned. Transfer to slow cooker.
  3. In the same skillet, sauté onions until golden and soft, about 8–10 minutes. Add garlic and cook for 1 more minute.
  4. Stir in balsamic vinegar, brown sugar, Worcestershire sauce, Dijon mustard, and beef broth. Scrape up browned bits from skillet.
  5. Pour onion mixture over the brisket in the slow cooker, ensuring meat is mostly covered.
  6. Cover and cook on low for 8–10 hours or high for 5–6 hours until brisket is fork-tender.
  7. Remove brisket and let rest 10 minutes before slicing.
  8. Transfer cooking liquid to a saucepan. Optional: stir in cornstarch slurry and simmer until thickened into gravy.
  9. Serve brisket slices topped with warm balsamic onion gravy.

Notes

  • For extra flavor, add mushrooms or carrots to the slow cooker.
  • Use honey instead of brown sugar for a sweeter note.
  • Mix in a splash of red wine with broth for deeper flavor.
  • Use smoked paprika for a smoky twist in seasoning.
  • Store leftovers in fridge for up to 4 days or freeze for 3 months.
