Step-by-Step Instructions for Slow Cooker Mongolian Beef

Follow these easy steps to create the perfect Slow Cooker Mongolian Beef:

Prepare the Beef and Sauce:

  1. Slice the Beef: Begin by slicing the beef flank steak into thin strips against the grain. This helps ensure the meat stays tender after cooking.
  2. Brown the Beef: Heat 2 tablespoons of vegetable oil in a large skillet over medium-high heat. Add the sliced beef in batches and sear them on all sides until they are browned. You don’t need to cook the beef through—just give it a good sear. Once done, transfer the beef to the slow cooker.
  3. Prepare the Sauce: In the same skillet, add the remaining 1 tablespoon of oil. Sauté the diced onion, garlic, and ginger until fragrant and softened, about 2-3 minutes. Be sure not to burn the garlic.
  4. Mix the Sauce Ingredients: In a medium bowl, whisk together the soy sauce, brown sugar, water, hoisin sauce, rice vinegar, and crushed red pepper flakes. Pour the sauce mixture over the beef in the slow cooker, stirring to combine.

Additional Tips for Slow Cooker Mongolian Beef

  • Use Fresh Ginger and Garlic: Fresh ginger and garlic will make a big difference in the flavor of the sauce, giving it a more authentic and aromatic taste.
  • Adjust the Heat Level: If you prefer a spicier dish, increase the amount of crushed red pepper flakes or add a bit of chili paste to the sauce.
