Step-by-Step Instructions
- Prepare the Beef: Place the thinly sliced beef into your slow cooker. Ensure the slices are separated and not clumped together for even cooking.
- Create the Sauce Base: In a medium bowl, whisk together the soy sauce, brown sugar, oyster sauce, rice vinegar, sesame oil, minced ginger, minced garlic, and red pepper flakes (if using). This mixture forms the delicious foundation of our Slow Cooker Mongolian Beef.
- Combine and Cook: Pour the prepared sauce mixture evenly over the beef in the slow cooker. Stir gently to ensure all the beef is coated with the sauce.
- Low and Slow: Cover the slow cooker and cook on LOW for 4-6 hours, or on HIGH for 2-3 hours, until the beef is tender and cooked through. The exact time will depend on your slow cooker’s settings and your beef cut.
- Thicken the Sauce: About 30 minutes before serving, in a small bowl, whisk together the cornstarch and cold water to create a slurry. Stir this slurry into the slow cooker with the beef and sauce.
- Final Simmer: Turn the slow cooker to HIGH (if it wasn’t already) and cook for another 30 minutes, or until the sauce has thickened to your desired consistency. Stir occasionally as it thickens.
- Serve: Once the sauce is thickened and the beef is perfectly tender, serve your Slow Cooker Mongolian Beef hot over cooked rice. Garnish generously with thinly sliced green onions for a pop of freshness and color.
