Instructions

1. Step 1: In a small bowl, combine 1 tbsp kosher salt, 1 tbsp black pepper, 1 tsp smoked paprika, and 1 tsp garlic powder. Rub this spice mix evenly over all sides of the 3 lb beef brisket.

3. Step 3: Spread 4 medium carrots, 3 parsnips, and 1 large sliced yellow onion evenly around the brisket in the slow cooker. Pour 2 cups beef broth over everything and tuck in 4 sprigs fresh thyme and 2 sprigs fresh rosemary.
4. Step 4: Cover and cook on low for 8-9 hours or on high for 4-5 hours until the brisket is fork-tender and vegetables are caramelized.
5. Step 5: Remove herbs before slicing the brisket against the grain. Serve with the cooked root vegetables and pan juices.
