How Long to Bake Corned Beef at 375°F for Perfectly Tender Results

Corned beef brisket is a staple for St. Patrick’s Day feasts and deli sandwiches. While many swear by boiling, baking corned beef in the oven results in incredibly moist, flavorful meat when done properly. But how long should you bake corned beef at 375°F? This guide will walk through ideal bake times plus tips for maximizing tenderness.

Oven Baked Corned Beef Benefits

Before jumping into bake times, let’s overview the benefits of using the oven:

  • Allows seasoning and glazes to caramelize and develop flavor

  • Provides even, consistent heat all around for uniform texture

  • Retains more natural juices than boiling

  • Requires only foil, no need to submerge in liquid

  • Allows fat to render slowly for ultimate tenderness

  • Gives some crust while still keeping meat very moist

  • Great way to serve a crowd without using stove space

How Long to Bake Corned Beef by Weight

The baking time primarily depends on the size and weight of your brisket. Here are general guidelines:

  • 1 pound corned beef: Bake for 1 hour at 375°F
  • 2 pounds corned beef: Bake for 2 hours at 375°F
  • 3 pounds corned beef: Bake for 3 hours at 375°F
  • 4 pounds corned beef: Bake for 4 hours at 375°F
  • 5 pounds corned beef: Bake for 5 hours at 375°F

For weights in between, round up to the next quarter pound and add 15 minutes per 0.25 pound.

Some key tips:

  • Weigh meat after removing from packaging and rinsing.

  • Use a meat thermometer to confirm doneness of 135°F.

  • Let rest 15 minutes before slicing for juices to redistribute.

Step-by-Step Instructions

Follow these simple steps for perfect oven baked corned beef:

  1. Preheat oven to 375°F. Cover a baking sheet in foil.

  2. Remove corned beef from packaging and rinse well. Pat dry.

  3. Place brisket fat side up on foil. Rub with mustard and seasoning.

  4. Wrap tightly in foil. Place on baking sheet seam side down.

  5. Bake for calculated time based on weight. Start checking temperature after 2 hours.

  6. Once 135°F, remove from oven and let rest 15 minutes.

  7. Carefully unwrap foil. Slice across the grain and serve.

Easy Mustard Glaze

Brush the brisket with a quick and easy mustard glaze before baking:

  • 1/4 cup Dijon mustard
  • 1/4 cup whole grain mustard
  • 1/4 cup yellow mustard
  • 1 tbsp brown sugar
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • 1/2 tsp paprika

Mix well and coat brisket before wrapping to bake. The glaze helps keep the meat very moist.

Doneness Tips

  • Use an instant read thermometer to check progress. 135°F is ideal.

  • If oven baking faster than expected, tent foil and reduce heat to 300°F.

  • If too moist, unwrap foil and bake uncovered last 15 minutes.

  • Let rest at least 10-15 minutes before slicing for best texture.

OVEN BAKED CORNED BEEF Recipe | St Paddy’s Day


How long to cook corned beef in the oven at 350 degrees?

OVEN: Set the oven for 350 °F (or no lower than 325 °F). Place brisket fat-side up. Barely cover the meat with water—about 1 inch—and keep the container covered throughout the cooking time. Allow about one hour per pound.

What temperature should corned beef be cooked at?

Corned beef is safe once the internal temperature has reached at least 145 °F, with a three minute rest time, but cooking it longer will make it fork-tender. Corned beef may still be pink in color after cooking. This does not mean it is not done. Nitrite is used in the curing process.

How long to cook corned beef at 180?

That said, tasted side-by-side, I actually preferred the slightly drier, flakier beef cooked at 175°F. It just seemed more like the corned beef I was used to. Further testing showed that for my taste, 180°F cooked for around 10 hours was just about ideal, producing meat that was simultaneously tender and succulent.

Can you overcook corned beef in oven?

And while brisket can take a much higher temperature than a steak can, it too can be overcooked. If all the collagen turns to gelatin, that’s good, but if all the gelatin cooks out of the corned beef, you’ll just have a crumbly, dried out piece of salted beef.
