How To Make Mongolian Beef
Full ingredients and instructions are also in the recipe card at the bottom of this blog post.
STEP ONE: Slice the 1 lb of steak into thin strips. Add the ½ cup cornstarch and sliced beef to a bowl. Toss everything together to evenly coat the beef. Shake off any excess cornstarch and add it to a plate.
STEP TWO: Heat the 2 Tbsp canola oil over medium-high heat. Add in ½ cup of each bell pepper (½ cup green, ½ cup yellow, ½ cup red), and ½ cup sliced yellow onion. Cook 4-6 minutes, until the edges turn a bit brown but aren't overcooked. Scoop these onto a plate, leaving the leftover oil in the pan.
STEP THREE: Now add another 2 Tbsp canola oil, and the 1 lb of beef in small batches, shaking off the excess cornstarch before you add it. Cook for 1 minute per side, then transfer to a plate. Add a bit more cooking oil if necessary while cooking all beef in small amounts at a time.
STEP FOUR: Once all beef is cooked add it to a plate lined with paper towel. Use a folded paper towel and spatula in the frying pan to soak up any excess oil. Leave any stuck-on pieces in the pan for flavor.
STEP FIVE: Add in the ½ cup soy sauce, ½ cup water, ⅓ cup brown sugar, 1 Tbsp freshly grated ginger, 3 minced garlic cloves and ¼ tsp red pepper flakes. Scrape off any cooked-on bits from the bottom of the pan using a silicone spatula. Cook for 1-2 minutes while stirring slowly the whole time.
STEP SIX: Add back in the beef and cooked vegetables and chopped green onion. Toss everything to coat evenly. Reduce the heat to low and cook 1-2 mins to thicken. Serve immediately.
Recipe Tips
- Cooking the beef in small batches will allow it to fry quickly. Beef should be cooked in a single layer with no touching. If too much is cooked at once, the pan will cool, and the beef will steam rather than fry.
- For a perfectly tender steak strip, try to fry the slices to medium rare. Then finish the cooking process in the sauce.
- Mongolian beef is typically made with a leaner cut which is easier to chew and more tender. But you can tenderize any cut of beef simply by marinating it for a few hours or overnight. Or using a meat tenderizer. Remove any excessive or hard-to-chew fat.
- Add some thinly sliced or julienned carrots, broccoli, or cauliflower. Mushrooms will also add more variety and flavor. Be sure to adjust your cooking times for softer vegetables.
- I used steak in this recipe, but pork or chicken will also be just as delicious. Cut the pork or chicken into thin strips as you would the steak. Both will take a bit longer to cook than steak will.
- You can serve this recipe on a bed of rice, with pasta noodles, mashed potatoes or in large pieces of lettuce to create lettuce wraps! This would also work with regular tortilla wraps.
Storing Leftovers
- Refrigerate - Cover any leftovers or store them in an airtight container for up to two days.
- To Freeze - You can prepare the sauce and freeze it in advance. If you have leftovers, seal them in an airtight container and freeze them for up to three months.
- To Reheat - Allow to thaw in the fridge overnight, and reheat in the microwave for 1-2 minutes, or on the stovetop at medium-high while constantly stirring.
