This slow cooker beef and broccoli recipe delivers tender, thinly sliced beef simmered in a rich, savory Asian-inspired sauce. It's a convenient and flavorful dish, perfect for a weeknight meal. The broccoli is added at the end to maintain its crisp texture and vibrant color. Serve it over steamed rice for a complete and satisfying meal.
For best results, partially freeze the beef chuck roast for 30-45 minutes before thinly slicing against the grain; this makes it much easier to achieve uniform pieces. Consider browning the sliced beef in a hot pan briefly before adding to the slow cooker to develop deeper flavor through the Maillard reaction. Ensure the cornstarch is fully dissolved in a small amount of cold water before whisking into the sauce to prevent lumps. Add the broccoli heads during the last 30-60 minutes of cooking to ensure they remain tender-crisp and retain their vibrant green color, preventing them from becoming mushy.
