I make it all the time. You can really really really cut down the work if you keep in mind that it's at its core...a stew.I am making this with the left over smoked prime rib. What a friggin lot of work. If I had known, I probably would have just reheated and eaten it with mashed potato.
You don't have to use the little pearl onions unless you just want to. I just use regular sweet onions (Maui, Walla Walla, Vidalia, whatever) diced up kinda medium sized and pre-sliced mushrooms. Get some carrots, trim the tops (peel if you want to, I do) potatoes, and some thyme and wine. I use those itty bitty potatoes that you don't even have to peel.
I get carrots in the bunch with the tops and don't even cut them into chunks, jut peel and cut the tops, but you can do that if you want to. I can normally have this in the oven ready to go in 20 mins. Cook (raw meat) 2.5 hours and voila...dinner.
The meat is already cooked so all you really have to do is throw the carrots and potatoes in a pot with the meat, thyme, and wine and let it cook for about an hour. Brown the onions and mushrooms and throw them in when its done. If you don't want to brown the onions and mushrooms, just put them in the pot with the other stuff when you put it in the oven.
