Man needs help in kitchen...crock pot tinga-ma-jig?

I coat my roast w/ flour and sear it a bit in oil on all the sides to seal in the juices 1 st. Then I put it in crock pot w/ a bit of water and onions . The crock pot won t brown the meat like your use to from the oven. I think it looks better w/ the meat is brown.. Adding potatoes and carrots later if you d like. The veggies take 4 hours at least to cook w/ the roast GL
