Let’s just start by saying that the words beef, beer and barbecue in a recipe title don’t make my husband sad.
When browning beef for a stew (whether you’re making it in a slow cooker, or a regular old pot or Dutch oven), it’s less important to get all the sides of the cubes of beef barely browned than it is to get a couple of sides nicely caramelized. Getting all six sides of a cube-ish piece of meat is a bit painstaking, and I’m absolving you from the task.
I actually read about a cool browning technique recently that helps if you are making a large amount of stew. Instead of browning all of the beef that’s been cut into small pieces, just buy the stew meat in a whole piece and cut it into steaks, or buy the meat in steak form. Heat a little oil in a pan until it’s quite hot and then sear the steaks on both sides, until nicely browned. Then cut the meat into 1 1/2-inch pieces. A nice deep browning on a couple of sides trumps barely browning on multiple sides.
If you didn’t have time to brown the beef at all, you would still end up with a flavorful beef stew, but it’s really worth it.
