Slow Cooker Korean Beef first posted when my youngest sister had just left for college in Korea. We had a fun little going away party for her where I served this Korean beef and it was amazing!

Tips for the Most Tender Beef:

I love cooking beef in the slow cooker because it cooks the meat so well. It is one of my favorite ways to cook it. The juicy beef gets so tender it falls apart in your mouth. That’s great news for a meat that can sometimes turn tough and dry when it cooks! Here are my expert tips to make this the best Korean beef you have ever made!

  • Slicing flank steak:The easiest way to slice your beef is to cut it when it is very cold. Cut against the grain.
  • Variations:Add broccoli in at the end of the cook time for a nice crunch. Or add it in about halfway through cook time for softer brocccoli.
  • Serving ideas:Serving with rice is a classic favorite. However, if you are watching your carbs you may want to try cauliflower rice or zucchini noodles instead. Add a colorful Asian Salad for a complete meal.

Storing Slow Cooker Beef:

After buying flank steak at the store you can refrigerate it for 3-5 days. If you are not ready to cook this delicious recipe right away you will want to freeze it until you are ready to cook it. Before freezing it, place extra airtight wrap around the store bought packaging to reduce freezer burn. The uncooked meat can stay frozen for 6-12 months.

Once you have cooked your perfect slow cooker beef, you will not want to miss the delicious leftovers! Eat them within 4 days if you are storing it in the refrigerator or 3 months if you decide to freeze your leftovers.
