Instant Pot Mongolian Beef Recipe

My easy recipe for Instant Pot Mongolian Beef with a flavorful homemade sauce will fool your family into thinking they are eating Chinese takeout. It’s a weeknight wonder!

My husband often complains that I make the same recipes — or at least variations of the same foods and flavors. I’ve been working hard on “jumping out” of my comfort zone and experimenting with new recipes to spice things up come dinnertime.

I love Chinese food and so does my family; however, my husband isn’t always convinced on my home takeout. So when he saw “Mongolian beef” on the menu board he raised an eyebrow. I know he had doubts in this meal; however, he never said it out loud.

As it came closer to dinner being ready, our home started to fill with the smell of a sweet and savory beef sauce — I could see my husband perk up. At that moment, I knew this recipe for Instant Pot Mongolian Beef was going to be a winner.

A little insider info — everything that is photographed for the blog is normally dinner that evening. I’ll try to cook dinner a little earlier then normal so that I have ample time before serving dinner.

We always have dinner together as a family. It’s a bit chaotic, but it’s how both my husband and I were raised and we feel it’s very important to sit as a family each and every night. Very rarely do we not sit and have dinner together.

One the rare occasions that my husband works late, my 4-year old cries that daddy isn’t eating dinner and he insists on waiting to eat with him. However, his stomach always wins that battle.

Since this meal made a lot I served the kids and my husband and then I photographed “dinner.” A few bites in and everyone was raving. My 1.5 year old was already done with the beef I served her by the time I sat down to eat. I had to go back and get a second helping of beef for her.

Because the kids were eating this I lessened the amount of red pepper flakes in the recipe. If you like it spicy you can add more. Just remember — it’s always better to add less than make it too spicy and inedible.

I paired this meal with white rice, steamed broccoli (great way to get the kids to eat it — just pour some of the extra Mongolian Beef sauce on top of it), vegetable egg rolls, and my sesame cucumber salad.

  • 1 1/2 pounds Flank Steak cut across the grain
  • 5 tablespoons Cornstarch divided
  • 1 tablespoon Grapeseed Oil
  • 8 cloves Garlic minced
  • 2 tablespoons Fresh Ginger minced
  • 1 1/4 cups Water divided
  • 1/2 cup Brown Sugar
  • 1 tablespoon Sesame Oil
  • 1/2 cup Low Sodium Soy Sauce
  • 1/4 teaspoon Crushed Red Pepper Flakes
  • 1 small White Onion quartered
  • 1/2 cup Shredded Carrots
  • 2 Green Onions thinly sliced (for garnish)
  • 1 teaspoon Sesame Seeds for garnish


  • Press the “sauté” button on the Instant Pot. Wait for the Instant Pot to read “HOT”.
  • While the Instant Pot preheats, add the sliced beef into a large gallon size baggie.
  • Sprinkle 2 tablespoons cornstarch over the beef. Seal the bag and shake well until the beef is coated.
  • Once the Instant Pot reads “HOT” on the screen, pour the grape seed oil in the pot. Then add the beef and sauté for 3 minutes, stirring frequently.
  • While the beef cooks, add the minced garlic, minced ginger, water, brown sugar, sesame oil, low-sodium soy sauce, and red pepper flakes to a large bowl. Whisk until smooth and then pour on top of the beef.
  • Add the onions and shredded carrots to the Instant Pot. Mix well, then close the lid and “seal the pressure valve”.
  • Select the “manual” setting for 8 minutes. Once it is done let it sit for 10 minutes for a “natural release”.
  • While the beef cooks make a cornstarch slurry with the 3 tablespoons cornstarch and the 1/2 cup of water. Set to the side.
  • Carefully, let the remaining pressure out of the pot, remove the lid, and cancel the cooking time. Then select “sauté”.
  • Stir the beef and add half the cornstarch slurry. Mix until thick. Add additional slurry if needed to thicken the sauce.
  • Serve with rice and steamed veggies and garnish beef with sliced green onions and sesame seeds.
  • Enjoy.


  • It’s best to prep the garlic and ginger ahead of time to ensure the beef doesn’t burn/overcook.
