- 1 large yellow onion, quartered
- 3 carrots, peeled and chopped

How to Make This crispy corned beef slow cooker Recipe
- 1. Prepare the Corned Beef: Rinse the corned beef under cold water. This helps to remove excess salt. If you want to, you can sear your corned beef prior to putting it into a slow cooker, for that you need to heat olive oil and add 3- 4 minutes on each side of you beef for better taste.
- 2. Layer the Vegetables: Place the quartered onion, chopped carrots, and chopped celery stalks in the bottom of your slow cooker. This creates a flavorful bed for the corned beef and prevents it from sticking to the bottom.
- 3. Add the Corned Beef: Place the corned beef brisket on top of the vegetables, fat side up. Sprinkle the minced garlic evenly over the corned beef and add the spice packet that came with the brisket.
- 4. Pour in the Broth: Pour the beef broth over the corned beef. This helps to keep the meat moist and adds another layer of richness to the flavor.
- 5. Slow Cook: Cover the slow cooker and cook on low for 8-10 hours, or on high for 4-5 hours, or until the corned beef is fall apart tender. Your tender slow cooked beef is almost ready.
- 6. Prepare the Dijon Crust: Once the corned beef is cooked, remove it from the slow cooker and save some cooking juices. In a small bowl, mix together the Dijon mustard and freshly cracked black pepper.
- 7. Broil: Preheat your broiler. Place the corned beef on a baking sheet lined with foil. Spread the Dijon mixture evenly over the top of the corned beef. Broil it for 3-5 minutes, or until the top is crispy and browned.
- 8. Rest and Slice: Let the corned beef rest for 10 minutes before slicing against the grain. This allows the juices to redistribute, resulting in a more tender and flavorful final product.
