This Slow Cooker Mongolian Beef is tender, saucy, and packed with sweet and savory flavor. Just 10 minutes of prep for a takeout-style dinner the whole family will love!
Thinly slice your flank steak against the grain (this makes it nice and tender), then dice it into smaller bite-sized pieces. Toss it in cornstarch along with a pinch of salt and pepper.
Layer it in the slow cooker. Add a little oil to the bottom of the slow cooker, then layer in the beef.
Stir in minced garlic and ginger, soy sauce, brown sugar, sesame oil, and a bit of water. Give it a good mix so everything’s coated.
Cook on high for 2.5 hours or low for 4–5 hours. The sauce will thicken and the beef will become super tender.
Top with sliced scallions and sesame seeds, and serve it hot over steamed rice.
