- 1 teaspoon dried minced garlic
- 1 teaspoon dried thyme leaves
- 2 teaspoons ground coriander
- ½ teaspoon ground mustard

How To Make Crock Pot Corned Beef Brisket
- Layer the onions: Place the sliced onion in the bottom of the crockpot.
- Prepare the brisket: Remove the brisket from the packaging and rinse it under cold water.
- Season the meat: Combine the dried seasonings in a small bowl and rub the mixture over the brisket, making sure it is coated on all sides.
- Slow cook the beef: Place the brisket on top of the onions. Cover and cook on low for 6-8 hours until the meat is fork-tender. Check that the internal temperature reaches 160℉.
- Rest and slice: Remove the meat to a cutting board and let it rest for 10-15 minutes. Slice against the grain.

Recipe Tips
- How do I know when it’s done? Fork-tender meat that breaks apart easily and reaches an internal temp of 160℉ means it’s ready.
- Should I rinse the brisket first? Rinsing helps remove excess salt from the brining process, but it’s optional.
- Can I add liquid to the slow cooker? It’s not necessary, but you can add ½ to ¾ cup water or broth if you prefer.
- Why is the meat still pink? Fully cooked corned beef remains pink due to the curing process; check doneness by texture and temperature.
- Can I cook it on high? For best results, always cook corned beef on the low setting.
