Slow Cooker Beef Tacos or Bulgogi Tacos are packed with flavor, no messy cleanup, and zero effort! Seriously, it doesn't get easier than that! And the best part, you can make it in a slow cooker or on a grill.
Heat a skillet over high heat and add 1 tablespoon of oil. Place the beef in a skillet and cook 3 minutes per side.
Place the beef in a slow cooker. Add the onion, garlic, ginger, brown sugar, tamari sauce, salt, and pepper. Cover and cook on low for 8-10 hours or on high for 4-6 hours. Once the beef gets tender, shred the beef with forks.
Gochujang mayonnaise: combine all ingredients for gochujang mayonnaise and set aside in the fridge until you're ready to add the sauce.
Serve over warm corn tortillas with the toppings and gochujang sauce.
