I made a pretty good crock pot the other day. First I put oven to 400 and covered each side of a corned beef briskett with oil first, then ground mustard, rosemary, thyme, and salt and pepper. Baked for 45 minutes fat side down in a glass casserole dish, no cover. While that went on I filled bottom of big crock pot with peeled pearl onions enough to cover the bottom well. I then a layer of baby carrots over top of that. Then I put a layer of cut up white potatoes. I diced up six cloves of garlic and sprinkled on top. I poured about 4 cups of beef broth in there. I put a healthy dose of ground mustard, rosemary and thyme, and put more pepper. But no more salt as corned beef can get salty on its own. I then transferred the beef brisket to the crock pot fat side up and pushed potatoes around to fit it. I then put halve cut Brussels sprouts as best I could around it. Put lid on on high for an hour. After a while when it was cooking down and room was made I put more Brussels sprouts in. I think it was about 1 to 1.5 pounds worth Brussels sprouts. Left on high for another hour. Then went to low for 3 hours.
It was outstanding. I am not sure why I did this in August. But I hit gold.
