1-First Step: Gather and Prep Your Ingredients Start by slicing 1 1/2 pounds of flank steak thinly against the grain; this helps it tenderize during cooking. To make it easier, pop the steak in the freezer for about 15 minutes first, as per our tips. Measure out 1/4 cup cornstarch and coat the beef evenly this step ensures the sauce thickens nicely and adds that desirable texture. For dietary tweaks, you can use tapioca flour if corn is an issue, keeping things adaptable for everyone.

2-Second Step: Build the Sauce in the Slow Cooker Add the coated beef to your slow cooker, then pour in 1 tablespoon toasted sesame oil, 1 teaspoon minced garlic, and 1 teaspoon minced ginger. Follow with 1/2 cup low sodium soy sauce, 1/3 cup brown sugar, and 1/2 cup water, stirring everything to cover the meat fully. This mix creates the flavorful base that makes Slow Cooker Mongolian Beef so irresistible, and you can adjust for heat by adding crushed red pepper flakes if you like it spicy.

3-Third Step: Cook to Perfection Cover the slow cooker and set it to high for 2-3 hours or low for 4-5 hours; keep an eye on it to avoid overcooking, as longer times might make the beef tough. This slow cooking process lets the flavors meld, resulting in tender, juicy beef that’s perfect for family meals. If you’re meal prepping, this step fits well into a busy schedule, allowing adaptations for different dietary preferences like using gluten-free soy sauce.

4-Fourth Step: Add Finishing Touches About 10 minutes before the end, stir in 1/2 cup green onions cut into 1/2 inch pieces for a fresh burst. This keeps them crisp and adds color to the dish, enhancing its appeal for celebration planners. Serve it over rice or with veggies like broccoli, as suggested in our easy slow cooker recipes for a complete meal that’s both nutritious and satisfying.

5-Final Step: Serve and Enjoy Once done, dish it up hot to keep the beef tender and the flavors at their best. Each serving clocks in at 308 calories, with 30g protein, making it a balanced choice for diet-conscious individuals.
