Sabrina’s Braised Corned Beef Recipe
While Corned Beef did originate in Ireland, it wasn’t always the traditional meal to celebrate St. Patrick’s Day. That tradition actually started with Irish-American immigrants. Most likely because it was a fairly inexpensive recipe for them to make. Now, for most of us, St. Patrick’s Day just wouldn’t feel right without this classic recipe. This tender beef is also perfect for a weekend dinner when you have some extra time to get it in the oven early.

Sabrina’s Tips
There are two steps that need to be followed to make sure this Corned Beef comes out perfectly. Make sure to sear your meat well as it will aid the cooking process as well as add a deeper flavor to the meat. Don’t skip this step! The second is to make sure you slice your meat against the grain so that you have tender fall apart pieces.

About this Recipe
Braising meat is an easy way to make it melt-in-your-mouth tender. To braise meat, you start by searing it in oil until the outside caramelizes. After searing, the beef is simmered slowly in cooking liquids like broth, wine, beer, or cider. The slow cooking time breaks down tough meat and adds flavor throughout the dish while searing ahead of time gives it a nice, crisp outer edge. It’s an easy way to make even the toughest cuts of meat tender and juicy.
Ingredients
- 4 pounds Corned Beef Brisket, flat: Corned beef is a brisket that has been cured in a salt brine that typically has brown sugar, peppercorns, mustard seeds, and various other spices. Pick the flat cut over the point cut as it is more uniform in size and will lay flatter when baking.
- 2 tablespoons Vegetable Oil: A basic cooking oil used to sear the beef. You can use canola or avocado oil if that is what you have. Just don’t use olive oil because it has a low smoke point.
- 1 Yellow Onion, sliced: A classic onion is used to lift the corned beef off of the pan. With the low and slow cook time, the onions will break down and become tender and sweet. You could use shallots or red onions if that is what you have on hand.
- 1 cup Beef Broth: The liquid used in the braising process. I recommend using a low sodium beef broth since corned beef can already be salty since it was cured. You could use water in a pinch if you don’t have any beef broth, but in that instance, I’d recommend a beer over water for some deeper flavor.
Can this be made ahead of time?
Yes, this dish is great if it is made ahead of time. The flavors actually tend to get better as it sits in the fridge overnight after cooking. It’s also much easier to slice when it is cold. Simply reheat it in the oven at 300 degrees for 20-30 minutes.

How to Store
- Serve: You shouldn’t leave cooked meat at room temperature for more than 2 hours.
- Store: Let the Braised Corned Beef cool down, then seal it in an airtight container to store in the fridge for up to 4 days.
- Freeze: To keep leftover corned beef longer, you can freeze it for 2-3 months.
Frequent Questions
No, you do not need to rinse the beef off. However, some people do feel that it is too salty due to the brining liquid, so if that is the case go ahead and rinse it. Be sure to dry it really well with paper towels.
It just needs a little more time in the oven. Corned beef has a lot of fat and connective tissue so it may just need more time to break down. Pop it back in the oven for 30-45 minutes. That should do the trick.
Variations
- Seasonings: For some extra flavor, season the brisket with spices like black pepper, caraway seeds, garlic salt or minced garlic cloves, fresh parsley, red pepper flakes, or bay leaves. Add your choice of seasonings along with the spice blend packet.
- Cabbage: Slice up a head of cabbage into wedges. A half-hour before the meat is done roasting, add the cabbage wedges in and bake them along with the Corned Beef.
- Oven Beer Braised Brisket: You can change up the braising liquid to make Oven Beer Braised Corned Beef. Use your favorite kind of beer in place of half of the beef broth in the recipe. A dark Irish ale, golden lager, light beer, or stout could all work well for this recipe.
Brown Sugar Mustard Glaze
- Try making a brown sugar mustard glaze for the meat by combining ½ cup brown sugar, ½ cup water, and ½ cup brown sugar in a saucepan while the beef is cooking.
- You can also add 1 ½ tablespoons of honey for extra sweetness.
- In the last half hour of the cooking time, take the corned beef from the oven and remove the foil.
- Brush the brown sugar mustard glaze over the beef.
- Cover the dish and bake for the remaining half an hour.
