how long to cook corned beef in oven

You’ll usually bake corned beef in the oven for about 1 hour per pound at 300–350°F (150–175°C) , covered, until it’s very tender and around 190–195°F internally.

Quick Scoop

• Plan on 45–60 minutes per pound of corned beef in the oven, depending on temperature and recipe.

• Most modern recipes use 300–350°F (150–175°C) and cook the meat low and slow, tightly covered so it turns fork‑tender.

• Start checking for doneness when a fork slides in easily and the internal temperature is about 190°F / 88–90°C for best tenderness.

Typical Oven Method (Example)

1. Preheat your oven to 300–350°F (many recipes choose 300–325°F for extra tenderness).

2. Place brisket in a roasting pan , fat side up, add about 1 inch of water, broth, or other liquid, and sprinkle on the spice packet.

3. Cover tightly with a lid or foil and bake for about 1 hour per pound (e.g., 3 lb = 3 hours), leaning toward the longer end if you want ultra‑tender slices.

4. Optional: Uncover for the last 15–30 minutes to brown the top, especially if you’ve added a glaze or extra seasoning.

5. Rest 10 minutes , then slice against the grain so it stays tender.
