Step 2: Sear the Beef - Heat the olive oil in a
large skillet over medium high heat. Add the beef in a single layer, working in batches if your skillet is crowded, and sear it for 2 to 3 minutes until several sides are nicely browned. The meat does not need to cook through. You are only building color, and that browned color gives the finished soup a richer, more developed taste. I know dirtying a skillet adds one more item to the sink, but this is the step that takes the broth from good to deeply savory.
