Ingredients

  

• 3 lb beef brisket
• 2 medium onion
• 3 medium carrot
• 2 medium parsnip
• 3 medium potato
• 2 tbsp olive oil for searing and roasting
• 1 tbsp brown sugar for caramelizing onions
• 1 tbsp balsamic vinegar adds depth to the onions
• 2 sprig thyme fresh
• 1 leaf bay leaf
• 4 clove garlic whole cloves for the slow cooker
• 2 cup beef broth
• 1 cup red wine
• 1 tsp salt
• 1 tsp black pepper

Method

 

1. Season the brisket generously with salt and pepper. In a hot cast‑iron skillet, add 1 tablespoon of olive oil and sear the brisket on all sides until a deep brown crust forms, about 3–4 minutes per side. Transfer the brisket to the slow cooker.
2. In the same skillet, add the sliced onions, brown sugar, and balsamic vinegar. Cook over medium heat, stirring frequently, until the onions are caramelized and golden, about 10 minutes. Transfer the onions to the slow cooker.
3. Toss the carrots, parsnips, and potatoes with 1 tablespoon of olive oil, salt, pepper, and thyme. Spread them on a baking sheet and roast in a preheated 425°F oven for 25 minutes, or until they are just tender and lightly browned.
4. Add the roasted root vegetables to the slow cooker. Pour in the beef broth and red wine, then toss in the bay leaf and whole garlic cloves.
5. Cover and cook on low for 7 hours (420 minutes), or until the brisket is fork‑tender.
6. Let the brisket rest for 10 minutes before slicing against the grain. Serve with the caramelized onions and root vegetables. Before serving, use a meat thermometer to ensure the brisket has reached a safe internal temperature.

Notes

Sear the brisket in a hot cast‑iron skillet until a deep brown crust forms; this caramelization locks in flavor. Roast the root vegetables separately at 425°F for 25 minutes so they develop a nice crisp before they mingle with the slow‑cooked gravy.

Food Safety Note: Always use a food thermometer to confirm your dish has reached a safe internal temperature before serving, and follow your country’s official food safety guidelines for meat, poultry, and slow-cooking.
