Notes

To store any leftovers, let the Korean beef cool completely. Place the beef in an airtight container and store it in the refrigerator for up to 3-4 days. You can also freeze the beef for up to three months. Just make sure to reheat it thoroughly before serving. Tips: Make sure to cut the beef against the grain for the best texture. If you prefer a thicker sauce, remove the beef when it’s done cooking and let the sauce simmer uncovered for a few minutes. Feel free to adjust the amount of red pepper flakes based on your spice preference. Variation: For a different twist, you can add vegetables like bell peppers or broccoli to the slow cooker during the last hour of cooking. This adds color and nutrition to your dish.
