Ingredients

• 3 lb beef brisket
• 2 tbsp olive oil
• 1 large, diced yellow onion
• 4 cloves, minced garlic
• 2, diced carrots
• 2 stalks, diced celery
• 1 cup beef broth
• 1/4 cup aged balsamic vinegar
• 2 tbsp tomato paste
• 1 tsp dried thyme
• 1 bay leaf
• to taste salt
• to taste black pepper

Instructions

1. Step 1: Preheat oven to 325°F (163°C). Pat 3 lb beef brisket dry with paper towels and season generously with salt and black pepper on all sides.
2. Step 2: Heat 2 tbsp olive oil in a large Dutch oven over medium-high heat. Add the brisket and sear for 5 minutes per side until deeply browned, then remove and set aside.
3. Step 3: Add 1 large diced yellow onion, 2 diced carrots, and 2 diced celery stalks to the Dutch oven and sauté for 5 minutes until softened. Add 4 minced garlic cloves and cook for 1 minute until fragrant.
4. Step 4: Stir in 2 tbsp tomato paste and cook for 2 minutes, then add 1 cup beef broth and 1/4 cup aged balsamic vinegar, scraping up all browned bits from the pot bottom.
5. Step 5: Return the seared brisket to the pot, nestling it among the vegetables. Add 1 tsp dried thyme and 1 bay leaf. Bring to a gentle simmer, cover tightly, and transfer to the oven.
6. Step 6: Braise for 3.5 hours, basting occasionally with the cooking liquid, until the brisket is fork-tender and pulls apart easily.
7. Step 7: Remove the brisket and vegetables from the pot. Strain the cooking liquid through a fine-mesh sieve into a bowl, discarding solids. Skim off excess fat from the surface.
8. Step 8: Simmer the strained liquid on the stovetop for 10 minutes until reduced by half and thickened enough to coat the back of a spoon, then serve over sliced brisket.
