Process Overview: How To Make Pot Mongolian Beef Step-by-Step

Please check the recipe card at the bottom of the post for exact quantities and detailed instructions (scroll down).

  1. Prepare the Beef

    Slice the flank steak into 1/4” thin (or thinner) slices across the grain of the meat. Add sliced beef and cornstarch to a large resealable plastic bag. Close and shake to coat well.

  2. Prepare The Sauce

    Mix the sauce ingredients. Set aside.

  3. Cook

    Cook according to your preferred cooking method. In the recipe card, I have included instructions for stovetop, instant pot, and slow cooker.

Cooking Methods: Stovetop vs. Instant Pot vs. Slow Cooker

  • Stovetop: Best for crispy, caramelized results; requires active cooking.
  • Instant Pot: Faster with tender meat, but less caramelized and may require extra sauce thickening.
  • Slow Cooker: Easiest for hands-off cooking with tender meat, but lacks crisp texture and needs time.

Extra Recipe Tips For Success 

  • Slice the flank steak into 1/4” thin (or thinner) slices across the grain of the meat.
  • Use low-sodium soy sauce for the best results.
  • Adjust the sweetness or saltiness of the sauce by varying the amount of brown sugar and soy sauce to taste.
A bowl of white rice topped with sliced beef in a dark sauce, garnished with green onions and sesame seeds, makes this easy Mongolian Beef a delightful dish.

Storage and Freezing Instructions

Store: Leftovers can be refrigerated for up to 3 days. 

Freeze: You can totally transform this into a freezer meal.  Just cut meat into thin slices and put it into a freezer bag. Bag the garlic and ginger in a smaller freezer bag. Bag the sauce ingredients in another bag. Then, put all components in a large freezer bag. On the day of preparation, cook as instructed in the recipe.

Instructions
 

Stovetop:

  • Slice the flank steak into 1/4” thin (or thinner) slices across the grain of the meat. Add sliced beef and cornstarch to a large resealable plastic bag. Close and shake to coat well.
  • Mix the sauce ingredients. Set aside.
  • Add 2 tablespoons of canola oil to a large frying pan and heat on medium-high heat. Add the steak, shaking off any excess cornstarch, to the pan in a single layer and cook on each side for 1 minute. Make this in batches to avoid crowding the pan.
  • When all the beef is done cooking, return it to the skillet. Add carrots, garlic and ginger and sauté for 2-3 minutes. Add sauce and mix to combine. Let it simmer for 5 minutes or until the sauce thickens and reduced.
  • Remove from heat and stir in green onions and sesame seeds (if using). Serve immediately over rice or steamed vegetables.

Pressure Cooker:

  • Slice the flank steak into 1/4” thin (or thinner) slices across the grain of the meat. Add sliced beef and cornstarch to a large resealable plastic bag. Close and shake to coat well.
  • Add the soy sauce, water, brown sugar, rice vinegar, sesame oil, red pepper flakes to the instant pot; mix to combine. Add the sliced beef, carrots, garlic, and ginger; mix until everything is well coated in the sauce.
  • Secure the lid to the instant pot and turn the venting knob to sealing position. Select "pressure cook", adjust the time to 10 minutes.
  • When the time is over, let the pressure release on its own for 5 minutes. Then, carefully turn the vent to "Venting" to release any extra pressure that might still be in there. Press “cancel”. Then remove the lid.
  • In a small bowl mix cornstarch with ¼ cup water. Add the mixture to the beef; mix to combine.
  • Turn the Instant Pot on and select "sauté" mode, then, adjust heat to normal. Let the beef simmer for 3-4 minutes, or until the sauce thickens.
  • Garnish green onion slices and sesame seeds, if desired. Serve immediately over rice or steamed vegetables.

Slow Cooker:

  • Slice the flank steak into 1/4” thin (or thinner) slices across the grain of the meat. Add sliced beef and cornstarch to a large resealable plastic bag. Close and shake to coat well.
  • Add to the slow cooker the soy sauce, water, brown sugar, rice vinegar, sesame oil, red pepper flakes; mix to combine. Add the coated beef, carrots, garlic and ginger; mix until everything is well coated in the sauce.
  • Cover. Cook on HIGH for 2-3 hours or on LOW for about 4 hours, until steak is cooked and tender.
  • Garnish green onion slices and sesame seeds, if desired. Serve immediately over rice or steamed vegetables.
Oriana’s Notes
 
Meat: Flank steak and sirloin are my preference.  You’ll want to slice them across the grain into three-inch-long pieces, about 1/4 inch thick. To slice the steak more easily, place it in the freezer for 20 minutes before slicing.
 
Store: Leftovers can be refrigerated for up to 3 days.
 
Freeze: You can totally transform this into a freezer meal.  Just cut meat into thin slices and put it into a freezer bag. Bag garlic and ginger in a smaller freezer bag. Bag sauce ingredients in another bag. Then, put all components in a large freezer bag. On the day of preparation, cook as instructed in the recipe.
