This incredibly easy slow cooker corned beef is tender and flavorful. Finish it by broiling for a perfectly crisp top. Add cabbage, carrots, and potatoes for a complete meal, or enjoy simply as delicious corned beef.
Make the paste. Stir the spice packet, black pepper, and garlic paste into a thick paste.
Build the base. Pour broth (or beer), onion, bay leaf, and thyme into the slow cooker.
Coat the beef. Place corned beef fat-side up; spread paste over the top.
Cook low and slow. Cover and cook on LOW 8–10 hours, until fork-tender.
(Optional veg) Add potatoes and carrots to the slow cooker for the last 2–3 hours on LOW, then add cabbage for the last 45–60 minutes — or simmer the veg separately in 2–3 cups strained cooking liquid on the stovetop until tender — or toss veg with oil and seasonings and roast at 425°F for 25–30 minutes until caramelized.
Crisp the top. Transfer beef to a sheet pan; broil on the bottom rack until the top is browned and crisp, 5–10 minutes, watching closely.
Rest 10 minutes; slice across the grain. Spoon cooking juices over to serve.

Notes
Expert Tips
Flat cut = neater slices; point cut = fattier/richer.
For less salt, rinse the brisket and pat dry before applying the paste.
High setting works in a pinch (6–8 hours), but texture is better on LOW.
