Baked Corned Beef and Colcannon

Last year I read about baking a corned beef brisket instead of the traditional method for boiling it, and I was intrigued. I picked up two on sale at the store yesterday and decided to try the baking method for dinner last night so I could be sure to get this blog written before St Patrick’s Day. The fact that I had no room in the fridge or freezer for two briskets might have had a little to do with my decision to cook it early.

Much to my surprise and delight, there were instructions right on the package. Yeah! They recommended adding the spice packet to the top for extra flavor during baking. But, I opted for a spicy sweet glaze of equal parts brown sugar and brown mustard and added the extra step of browning the glaze – an extra 5 minutes, no big deal. Just don’t tell the boys I added mustard to it, please! Little do they know the seasoning packet is loaded with mustard seeds and the like anyway.

The results were delicious. The texture is a bit firmer than the boiling method. And the addition of the glaze to the top added an extra level of flavor I really enjoyed. Sir Snubs A Lot enjoyed it too, having three helpings!

If you want to bake potatoes and carrots along with the brisket, add them around (on top of) the foil the last hour of cooking. I went with a little something different here too. I was checking out some of my favorite blogs while the brisket was cooking and found this awesome recipe for Colcannon at Lydia’s Flexitarian Kitchen. I didn’t have the leeks she called for, so I skipped that step and added chopped onion when I sautéed the kale. Marvelous!!! I want to get some leeks and try it with those when I make the other brisket.


We have a lot of bread in the house at the moment so I didn’t make our traditional Irish Soda Bread last night, but I will in the next few days.

As far as the cabbage goes, none of us care for the taste or smell of cooked cabbage, so we always pass on this tradition.

I know St. Patrick’s Day is on a Monday this year so it might not fit into your schedule to bake a brisket for 3+ hours. But, you can always make it on Sunday or pick up an extra one and try this recipe later.
