The beef is fall-apart tender, marinated in the most mouthwatering sauce — a dream to eat — and tastes incredible poured over rice.

This will likely join your weekly dinner rotation. It’s requested often in my house, and even picky eaters adore it.

Family favorite

You can easily add vegetables — toss broccoli or green beans into the slow cooker during the last hour of cooking, or serve steamed vegetables alongside.

The sauce takes only a few minutes to prepare, then simmers in the slow cooker for hours. The result is incredibly tender beef with a rich, flavorful sauce. I always spoon extra sauce over my rice to soak up every bit of it.
