For tender, safe corned beef, aim for an internal temperature around 190–200°F (88–93°C), regardless of cooking method.

Here’s the quick scoop:

  • Food safety minimum: Corned beef is technically safe to eat at 145°F (63°C), but at this point it will still be quite tough because brisket is a very hard-working muscle.
  • Tender and sliceable: Most pros recommend cooking until the internal temp reaches about 180–190°F (82–88°C) for moist, fork-tender slices that hold together.
  • Fall‑apart soft: If you want shreddable, “fall-apart” corned beef, take it a bit higher, in the 190–205°F (88–96°C) range, checking frequently so it doesn’t go dry or mushy.

Typical cooking setups:

  • Simmering/boiling: Keep the cooking liquid at a gentle simmer, about 190–205°F (88–96°C), and cook 2.5–3 hours or about 1 hour per pound, then verify the meat is 180–200°F inside.
  • Oven-braising/roasting: Bake around 300–325°F (150–165°C) until the thickest part hits about 190°F and a fork slides in with little resistance.
  • Slow cooker: Low 8–10 hours or high 4–5 hours, again checking that internal temp lands near 190°F for best texture.

A simple test besides temperature: slide a fork or probe into the thickest part; when it goes in and out with almost no resistance, your corned beef is ready.
