Ingredients
- 3 tbsp olive oil (divided)
- 4 lb beef brisket
- 2 tsp sea salt (or to taste)
- 1 tsp freshly ground black pepper
- 1 lb yellow onions (2 medium), sliced into thick strips
- 1 lb mushrooms, thickly sliced
- 6 garlic cloves, peeled and chopped (do not press)
- 2 cups low sodium chicken stock or beef broth
- 2 1/2 tbsp Worcestershire sauce
Instructions
- Season the Brisket: Generously season the brisket with 2 tsp of salt and 1 tsp of black pepper.
- Sear the Brisket: Heat a large heavy skillet or cast iron pan over high heat. Add 1 tbsp of olive oil, and once hot, add the brisket, fat side down. Sear for 4-5 minutes per side until browned. Transfer the brisket to the slow cooker with the fat side facing up.
- Caramelize the Onions: In the same pan, add 1 tbsp of olive oil and sliced onions. Sauté for 5-7 minutes or until the onions are caramelized. Place the onions over the brisket in the slow cooker.
- Sauté the Mushrooms and Garlic: Add more oil to the pan if needed and sauté the mushrooms until softened, about 5 minutes. Place the mushrooms over the brisket in the slow cooker. Sprinkle chopped garlic over the top.
- Prepare the Broth: In a separate bowl, combine the chicken stock and Worcestershire sauce. Pour the mixture over the brisket.
- Slow Cook the Brisket: Cover the slow cooker and cook on low for 7-8 hours or until the brisket is tender and easily pulls apart with forks.
- Rest and Shred: Once the cooking is complete, turn off the slow cooker and let the brisket rest, covered, for 15 minutes. Remove and discard excess fat from the top, then shred the beef using forks. Return the shredded beef to the slow cooker to soak up the juices.
- Serve: Serve the shredded brisket and mushrooms, spooning the slow-cooked juices over the top for extra flavor.
Tips
- Searing the Brisket: Searing the brisket before slow cooking helps to lock in flavors and enhances the richness of the meat. Don’t skip this step!
- Resting Time: Allowing the brisket to rest before shredding helps the juices redistribute, keeping the meat moist and tender.
- Broth Variations: You can use beef broth instead of chicken stock for a richer flavor.
Variations and Substitutions
- Vegetable Broth: For a lighter alternative, use vegetable broth in place of chicken or beef broth.
- Mushroom Variations: Try different types of mushrooms, like cremini or portobello, for added depth of flavor.
- Add Veggies: Feel free to add carrots or potatoes to the slow cooker for a heartier meal.
