1 tablespoon vegetable oil

3-4 cloves garlic, minced

2 teaspoons fresh ginger, minced

3/4 c. water

How to make Easy Slow Cooker Mongolian Beef

Step 1: To a large resealable plastic bag, add the sliced flank steak and cornstarch. Close the bag, then shake to coat the steak well. Alternately, you can do this in a large mixing bowl as well.

Step 2: Add the vegetable oil, garlic, ginger, water, soy sauce, brown sugar, and Sriracha sauce to the bottom of a slow cooker. Stir well to combine.

Step 3: To the slow cooker, add in the coated flank steak and carrots. Stir to coat with the sauce.

Step 4: Cover the slow cooker, set on high, and cook for 2 to 3 hours. Or set on low to cook for 4 hours until the steak is tender.

Step 5: When done, serve the Mongolian Beef over white rice, garnished with some green onions and sesame seeds. Enjoy!
