This Easy Mongolian Beef is a restaurant takeout copycat dish that takes only 20 minutes to make! Flavorful beef in sauce, served with steamed broccoli, rice bowl style.
Make the sauce mixture, by whisking the following in a measuring cup: soy sauce, brown sugar, minced garlic, sweet chili sauce, ginger and cornstarch. Set aside.
Heat up oil in a large pan. Toss beef with salt, pepper and cornstarch. Add half beef to pan and cook 1 minute per side, just until almost done. It will finish cooking with sauce. Remove onto a plate, repeat with second part of beef. Add more oil to pan if needed. When the second batch is done, add the first one and the sauce. Mix well. Stirring often, cook until the sauce thickens.
Serve with cooked rice and steamed broccoli. Garnish with chopped green onions.
