  • About 1.5 lb flank steak, sliced against the grain into 1/4" thin strips
  • 1/2 medium yellow onion, diced
  • 1/2 heaping cup carrots, shredded (optional)
  • 1/3 cup brown sugar
  • 1/2 cup low sodium soy sauce
  • 2 Tbsp sesame oil (divided)
  • 3-5 garlic cloves, minced (your call on amount)
  • 3/4 cup vegetable broth (beef broth is great too)
  • 1 Tbsp grated ginger (save for after Instant pot quick release)
  • 1/8-1/4 tsp red pepper flakes (optional-I like this dish spicy, but my kids are a different story, so I don't add it if cooking for them)

Sauce Thickener

  • 2 Tbsp cornstarch or arrowroot powder
  • 3 Tbsp water


  • 1 Tbsp sesame seeds
  • 4 green onions, chopped


  1. Set Instant Pot to Sauté mode.
  2. Add 1 Tbsp of the oil to Instant pot once hot.  Add steak in batches and brown, stirring occasionally. I do it in 3 batches.  Once browned, remove from pot and set aside.
  3. Add remaining Tbsp of oil, onions & carrots.  Sauté about 2 mins.
  4. Add garlic (& red pepper flakes if adding) to pot, stirring about 1 minute or fragrant.
  5. Add broth, soy sauce and brown sugar to pot.  Stir to combine, scraping all bits off the bottom of the pot with a wooden spoon.
  6. Return beef to pot. Give it a quick stir.
  7. Close Instant Pot and set to High pressure for 9 mins.
  8. Quick release once cooking is complete.
  9. Set the Instant Pot back to Sauté and once sauce is simmering add your ginger to the pot.  Stir to combine.
  10. While sauce is simmering, stir together cornstarch and water together in a small bowl/ramekin and quickly add to pot.
  11. Wisk the cornstarch thickener into the sauce, consistently stirring until sauce thickens, doesn't take more than a minute.
  12. Stir in the sesame seeds.
  13. Turn off and unplug your Instant Pot.  Top plates with green onions and enjoy!



Serve over your favorite rice or noodles. I prefer to serve the Mongolian Beef over Jasmine rice with Green Onions. Add some red pepper flakes over individual dishes for those who prefer more heat.
