I've never made a roast before, but I tried this and it was a great combination:
1 beef roast (whichever cut you prefer)
1 can cream of chicken soup
1 can cream of mushroom soup
1 can beef broth
1 package dried onion soup mix
dash of worchestshire sauce
Put all the veggies you want in the bottom of the crock pot. Flour the roast on all sides and rub garlic powder and pepper on the outside. Place in the crockpot. Mix in a bowl the other ingredients. Pour over the top. Cook on low for 8-10 hours.
This turned out to be pretty tasty and mess free and hassle free.
