I found a pot roast at a decent price today. It was about 2 pounds worth.
Here's how I prepared it: First, I fried 3 pieces of bacon slowly so that they would be crispy, then I set them aside in a paper towel. Next, I turned up the temp of the bacon skillet to medium-high, and seared each side of the roast in the bacon grease (about 30-60 seconds on each side). I chopped up an onion and 3 TBSP butter and put a third of it in the middle of my crockpot, placing the roast on top (and then pouring the leftover bacon grease over it). The other two-thirds of the onion and butter went right on top of the roast. I set my crockpot to HIGH.
Last time I made pot roast this way, I had a bigger roast and more time for cooking, so I did it on LOW and for longer (maybe 7 hours?). It turned out great!
And what about the bacon? After it cooled, I crumbled it and stored it in the frig to use on another day for potato soup.
Some of the bacon landed in my mouth (BAD, BAD bacon!).
