This Brisket with Caramelized Onions recipe makes tender, slow-cooked beef with deeply caramelized onions and a rich, savory sauce. It’s a comforting main dish that works beautifully for holidays, family dinners, and special occasions.
Why This Brisket Works
Slow cooking allows the brisket to become tender and juicy while the onions cook down into a rich, sweet layer. Garlic, beef broth, and Worcestershire sauce add extra depth to the flavorful cooking liquid.
Ingredients
- 4–5 lb beef brisket
- 3 large yellow onions, thinly sliced
- 5 garlic cloves, minced
- 2 tablespoons olive oil
- 2 tablespoons butter
- 2 cups beef broth
- 2 tablespoons Worcestershire sauce
- 1 tablespoon Dijon mustard
- 1 tablespoon brown sugar
- 2 teaspoons smoked paprika
- 1 teaspoon dried thyme
- 1 teaspoon onion powder
- 1 teaspoon salt
- ½ teaspoon black pepper
- ½ cup red wine, optional
- 2 tablespoons fresh parsley, chopped
How to Make Brisket with Caramelized Onions
- Prepare the brisket: Pat the brisket dry and season both sides with smoked paprika, thyme, onion powder, salt, and black pepper.
- Sear the beef: Heat olive oil in a large oven-safe Dutch oven over medium-high heat. Sear the brisket for 3–4 minutes per side until deeply browned. Remove and set aside.
- Caramelize the onions: Reduce the heat to medium. Add butter and sliced onions to the same pot. Cook for 15–20 minutes, stirring regularly, until softened and golden brown.
- Add the garlic: Stir in the minced garlic and cook for about 1 minute.
- Make the sauce: Add the beef broth, Worcestershire sauce, Dijon mustard, brown sugar, and optional red wine. Stir well and scrape up any browned bits from the bottom.
- Add the brisket: Place the brisket back into the pot, fat side up. The liquid should come partway up the sides of the meat.
- Slow cook: Cover tightly and place in a 325°F (165°C) oven. Cook for about 3½–4½ hours, or until the brisket is fork-tender.
- Rest the brisket: Remove the brisket from the oven and let it rest, covered loosely with foil, for 20–30 minutes.
- Slice and serve: Slice the brisket against the grain and spoon the caramelized onions and sauce over the top. Garnish with fresh parsley.
Tips for the Best Brisket
- Sear the brisket well to develop a deeper flavor.
- Slice the onions thinly so they caramelize evenly.
- Keep the pot tightly covered during cooking to prevent the brisket from drying out.
- Cook until the meat is fork-tender rather than relying only on cooking time.
- Always slice brisket against the grain for more tender pieces.
