Tips
Test doneness by piercing the thickest part of the brisket with a fork - it should slide in easily when properly tender.
Save some cooking liquid as a flavorful broth for reheating leftovers or making soup.
Let the brisket rest for 10 minutes before slicing to retain juices, and always slice against the grain for maximum tenderness.
Good to Know
Refrigerate cooked corned beef and vegetables for up to 4 days in separate containers.
Can be cooked 1-2 days ahead and reheated gently with some reserved cooking liquid.
Serve hot with mustard, horseradish, or Irish soda bread alongside.
Common Mistakes
Don't skip rinsing the brisket to avoid overly salty results.
Avoid cutting with the grain which makes meat tough and stringy.

FAQ
Can I cook this without the seasoning packet?
Yes, but add your own spices like bay leaves, peppercorns, coriander seeds, and pickling spice for traditional flavor.
What if my brisket isn't tender after the recommended time?
Continue cooking and check every 30 minutes - older or thicker cuts may need extra time to become fork-tender.
How long will leftovers keep in the refrigerator?
Properly stored cooked corned beef and vegetables will keep for 3-4 days refrigerated and can be frozen for up to 3 months.
