I was going to be lazy and just get a "buy and bake" Shepard's Pie from Costco, but mine didn't make them this year. I ended up getting a hunk of corned beef for corned beef and cabbage. I just put the meat in the oven. I'm experimenting with a mix of ideas from several online recipes, taking a little from each one, so it's a gamble today.

The corned beef is going in the oven at 325 deg inside a dutch oven with a bottle of Guinness poured over it. In about 90 minutes I'm going to throw in some chunks of potatoes, carrots, and onions. Separately in 2.5 hours or so, I'm going to put a mix of seasoned taters, onions, and cabbage all with a light coating of olive oil in a separate cast iron pan and stick them in the oven for an hour or so to roast, in hopes of them and the corned beef all getting done at the same time.
If I would have gotten up an hour earlier, I might have made some soda bread too, but I was lazy, so just the meat and taters today.
I'm deciding if I should wash it down with Guinness or Red Breast. :)
