Slow Cooked Beef Brisket is a tender, slow-braised beef dish simmered with onions, carrots, celery, and herbs until richly flavored and fork tender.
3 to 4 pounds beef brisket
2 teaspoons salt
1 teaspoon freshly ground black pepper
1 tablespoon vegetable oil
2 large onions, sliced
4 cloves garlic, minced
3 carrots, cut into chunks
2 celery stalks, sliced
2 tablespoons tomato paste
3 cups beef broth
1 tablespoon Worcestershire sauce
1 tablespoon brown sugar
3 sprigs fresh thyme
2 bay leaves
Pat brisket dry and season with salt and pepper.
Heat oil in a Dutch oven over medium-high heat and sear brisket on both sides until deeply browned.
Remove brisket and cook onions until softened, then add garlic and cook briefly.
Stir in tomato paste and cook for one minute.
Add a splash of broth to deglaze the pot, scraping up browned bits.
Return brisket to the pot and add carrots and celery around it.
Pour in remaining broth, Worcestershire sauce, brown sugar, thyme, and bay leaves.
Bring to a gentle simmer, cover, and cook on low heat for 3 to 4 hours until tender.
Remove brisket and rest for 20 minutes before slicing against the grain.
Simmer sauce uncovered if needed to thicken, then return sliced brisket to coat before serving.
