No St. Patrick's Day dinner would be complete without Corned Beef!

We always kick ourselves and wonder why we don't eat it all year long. It's that good!

Why oven-baked corned beef?

For years we cooked our beef brisket under liquid either in a dutch oven, on top of the stove, or in a slow cooker. Both ways were pretty much just boiling it.

It's a super easy way to make a fall-apart corned beef.

However, the entire texture and flavor was the same inside as it was on the outside.

Once we tried baking our brisket we never went back to boiling it.

The roasted brined exterior is crispy delicious and the meat is tender and juicy.

It also slices up beautifully for a show-stopper presentation.

What is Corned Beef?

Have you ever wondered how this brisket got known as Corned Beef?

"Corning" is a form of curing and has nothing to do with corn. In times before refrigeration, meat was dry-cured in coarse "corns" of salt. I'm a foodie geek because I just love these little history tidbits.

The Corned Beef we buy today is a beef brisket that has been brine-cured in spices and curing salt which gives the corned beef brisket that deep pink hue.

How to pick out the perfect Corned Beef Brisket

Beef Briskets can vary from about three pounds up to a very large brisket. The size will not determine the quality of the outcome.

A whole brisket is cut into either a "Flat" or Point". Both bake beautifully but here's the difference.

Point is a rounder thicker piece of meat. It generally has more fat marbling so is very flavorful.
Flat can also be referred to as round and is a thinner piece of meat and it's a little leaner. It's easier to slice so it makes a nice presentation.

They're both delicious so don't stress if you don't know the difference or don't have the option of one versus the other.

Also, briskets aren't delicate pieces of meat so don't overstress ruining it.

When you're planning on the size of brisket you want to serve, it's helpful to know that a traditional serving is considered about 3/4 pound per person.

Baked Corned Beef FAQ's

Do you have to rinse off the brining liquid before cooking?

We always rinse the brining fluid off of the meat. This removes extra salt.

Rinsing will not change the flavor of the meat since the whole piece has been brined.

Do you cut the fat off of the Brisket?

The fat cap can be very thick. We trim the fat within one inch of the meat. Leaving some fat adds flavor.

How to bake Corned Beef in the oven

Rinse the brining fluid off and pat the brisket dry.
Trim the fat cap within 1 inch of the meat.
Place a grate in the bottom of a roaster or baking dish.

Grates sitting in the bottom of a roasting pan

Place the meat on top of the grate fat side up and sprinkle it with the seasoning packet if desired. We generally do. However, you can make your own brine and seasoning too.

Fill the bottom of the roasting pan with water level with the bottom of the grate (directly under the brisket).
Cover the pan with the lid or aluminum foil for two-thirds of the baking time.
Remove the lid or foil.

V egetables can be added to the brisket. They will need approximately 1-1/2 hours to bake.

How long to bake

Briskets like a longer cooking time. We cook our brisket for 1 hour per pound for a 2 to 3-pound brisket. A larger brisket (4 to 6 pounds) will take 3 to 3 1/2 hours. It's safe to eat when it reads 145°F when tested with an instant-read thermometer.

However, briskets are a fatty cut of meat and this fat needs to render "cook into the meat" so additional baking is best. I usually bake to 185+. If the meat looks like it's getting to crispy, it's going to dry out. Put the lid back on before you get to this stage.

Tips:

Make sure you let the brisket rest after removing it from the oven so the juices are redistributed and don't just run out of the meat.
If you want shredded corned beef instead of sliced, you can cook it up to an internal temperature of 185°F to 210°F.
You can up your temperature to make it bake a little quicker but don't bake it below 325°F for food safety concerns.

Slicing tips

Let the brisket rest before slicing. It will hold the juices if you let it sit 15 to 20 minutes.

Make 1/8 to 1/4 inch slices across the grain. If you cut the meat with the grain it will shread.

Storing tips

According to the USDA corned beef should be refrigerated within 2 hours of cooking and used within 3 to 4 days. Brisket can be frozen and should be used within 2 to 3 months.

6 lbs Corned Beef Brisket with seasoning packet

Preheat the oven to 325°F, and put a grate (roasting rack) in the bottom of a roasting pan or baking dish large enough to hold the meat.
Rinse the corned beef to remove packing liquid and additional salt. Pat it dry with a paper towel.
Trim the fat cap within 1-inch of the meat and put it fat-side up on the grate. Fill the bottom of the pan with water up to the edge of the grate. Place the meat on the grate and sprinkle it with the seasoning packet.
Cover the pan with a lid or foil. Bake the meat covered for 2 hours. Remove the lid and roast for an additional 1 hour or until an instant-read thermometer reads 185°. Vegetables such as potatoes, carrots, and cabbage can be added the last hour and a half.
Allow the meat to rest for 15 minutes and then cut across the grain.
