Prep the Beef and Vegetables
Rinse the brisket under cold water to remove excess salt, then pat dry.
Cut cabbage into wedges; cut potatoes and carrots into large, even pieces so they hold shape.
Choose a Cooking Method
Stovetop (Classic)
Place brisket in a large Dutch oven or pot, fat‑side up. Add enough broth/water to about 2–3 inches above the meat.
Add the spice packet, bay leaves, and onions.
Bring to a gentle boil, then reduce to a simmer.
Simmer 2.5–3 hours, or until tender (180–205°F / 82–96°C).
Add potatoes and carrots about 1 hour before end; add cabbage during the last 15–20 minutes.
Oven (Hands‑Off)
Preheat oven to 325°F (163°C).
Place brisket in a Dutch oven with broth/water, spice packet, and bay leaves.
Cover and bake 2 hours, then add potatoes and carrots, cover again, and bake 1–1.5 hours more.
Add cabbage in the last 15–20 minutes.
Slow Cooker (Set‑and‑Forget)
Place brisket in a large slow cooker and add spice packet, bay leaves, onions, and broth/water to cover.
Cook on Low 8–9 hours or High 4–5 hours, until tender.
Add potatoes and carrots during the last 2–3 hours and cabbage during the last 1–1.5 hours.
Add Mediterranean Flavors
About 1 hour before finish, brush the top of the brisket with Dijon mustard mixed with a little olive oil and brown sugar (optional).
Add 1–2 tbsp apple cider vinegar to the broth if you like brighter flavor.
Rest, Slice, and Serve
Transfer brisket to a cutting board, let rest 10 minutes, then slice thinly against the grain.
Arrange meat on a platter, surround with vegetables, and drizzle with a little olive oil and broth.
Garnish with chopped parsley and serve with mustard/horseradish, bread, and a side of green salad if desired.
