Eye of round roast
Best eye of round I ever prepared was done by using my (modified to maintain proper temperature) crockpot and a foodsaver for a homemade sous vide setup. Flavor and juices stay in the vacuum sealed bag, and the outside of the meat gets a quick browning after the inside is finished - if I remember correctly, it was about 3-4 hours at 130 degrees.
There are over 300 posts on this board related to cooking eye round, but I found this one to be very helpful:
I tried it with good results, but it took longer for me to do than I'd expected. It may be my oven holding the lower temperature steady. But it was delicious and I'm planning to do it again.
There will always be some difference between the outside (with most exposure to the heat) and the inside -- but this method was much more even.
