One of my go to family meals is a venison pot roast. It could not be much easier.
2-3 lbs Venison Rump roast
1 lbs Carrots, pealed and rough cut
2 lbs Small Red Potatoes (or whatever Potato you have)
2 Medium onions cut into 8 pieces
Salt and pepper to taste
1 Tbl of oil
Liberally salt and pepper the rump roast. Put oil in a hot Dutch oven and sear the roast on all sides. Get a nice brown crust. Toss in the onions and cook for a couple of minutes. Add water or stock to just about cover the roast. Add the carrots and potatoes. Lid and put into a 325 degree oven for about 3 hours. Longer is usually okay. After cooking, put a couple of cups of the cooked stock into a sauce pan. Bring to a low boil and thicken with equal parts corn starch and water. Now you have gravy too.
Put this into the oven before church on Sunday and lunch is pretty much cooked by the time you return home. You could also cook this in a crockpot. Just plan on a 6-8 hour cook time.
