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.
