We picked up some ground bison for the 4th of July, but while we were there we spotted some a bison roast and decided to try it. I used my usual method to make the roast, and it tasted great.
1 2.5 lb bison roast 1 bottle beer (I used Corona Light) 1 bottle of water
Place in slow cooker and cook on high 3-4 hours or low 6-8.
Verdict: We liked it, but didn't love it. To us, it tasted just liked a beef roast, and was not worth the extra $3 per pound that we paid for it. Usually bison has a little different taste from beef, but it is very hard to differentiate with a roast.
