Got this from the infamous crockpoting site
3-4 pounds beef roast
1 tablespoon dried onion flakes, or 1 medium yellow onion, diced
2 tablespoons soy sauce
1 (16 ounce) can of whole berry Cranberry sauce
Put in the roast (frozen is fine), and add the onion and soy sauce. Pour in the entire can of cranberry sauce over the top, smushing it to cover the meat. Do not add water. Cover and cook on low for 7-9 hours, or on high for 5-6. Low is best, as the meat will be falling apart and more juicy. But High is fine, you may just need to cut it up about an hour before serving to let the juice soak up into the meat.
I served it over mashed potatoes and with green peas. It was so good. Everyone, even my 2 year old loved it. He normally gags with mashed potatoes. IDK
This is the best tasting roast I have ever had. There is a bit of sweetness with the cranberry.... the broth is great! And it's sooooooooooo easy!
