How to Make Easy Crock Pot Mongolian Beef

Prep Beef & Aromatics:

Thinly slice the flank steak against the grain. Mince the garlic and grate the fresh ginger. This simple prep ensures everything is ready for your delicious Easy Crock Pot Mongolian Beef, setting you up for success.

Whisk Sauce:

In a medium bowl, whisk together the soy sauce, brown sugar, beef broth, cornstarch, rice vinegar, sesame oil, Sriracha (if using), black pepper, and red pepper flakes. This creates the rich, savory base for your Easy Crock Pot Mongolian Beef.

Combine & Coat:

Add the sliced flank steak, minced garlic, and grated ginger to the prepared sauce mixture. Stir well to ensure every piece of beef is thoroughly coated. This step is crucial for infusing flavor into the meat.

Slow Cook:

Pour the entire mixture into your slow cooker. Cover and cook on low for 4-5 hours or on high for 2-3 hours until the beef is incredibly tender and the sauce has thickened beautifully.

Thicken & Garnish:

Once the beef is tender, check the sauce consistency. If needed, you can remove the lid for the last 30 minutes to allow it to thicken slightly. Stir in half of the sliced green onions.

Serve Warm:

Ladle your comforting Easy Crock Pot Mongolian Beef over steamed rice or noodles. Garnish generously with the remaining fresh green onions and toasted sesame seeds. Enjoy this delightful, satisfying family meal!
