  • 2 pound Flank steak Thinly sliced into half inch strips
  • 2 tbsp Butter Melted, Unsalted
  • 1 can Diced tomatoes with green chiles 10 oz. can
  • 1-2 tbsp Lime juice
  • 2 tbsp Taco seasoning
  • 1 tsp Garlic powder
  • 1 tsp Onion powder
  • 1 tsp Black pepper To taste
  • Salt To taste
  • 1 tbsp Cornstarch Dissolved in 1 tbsp water
  • 1/2 cup Green peppers Thinly sliced, Optional
  • 1/2 cup Onions Thinly sliced, Optional
  • 2 tbsp Cilantro Fresh, Roughly chopped, For garnish


  • In the instant pot (don't turn it on yet!), add steak strips, melted butter, diced tomatoes with green chiles, lime juice, taco seasoning, garlic powder, onion powder, black pepper, salt.
  • Mix until combined.
  • Put the lid on and now, turn on the pressure cooker. Turn the the valve to “Sealing.” Select “Manual” mode and set timer for 12 minutes.
  • When the cook time is over, let the pot sit undisturbed and allow the pressure to release naturally for 5 minutes. Then, do "quick release" to allow remaining steam to escape.
  • Turn on the "Saute" mode and mix in the dissolved cornstarch slurry.
  • Add thinly sliced green peppers and onions (optional).
  • Cook uncovered for a few more minutes to reduce liquid further and to make onions and peppers tender (if you added those).
  • Garnish with lots of fresh cilantro.
  • Use a slotted spoon to remove steaks from pot and fill tacos and pour some juices on top.
  • Add toppings of your choice and enjoy!


  • Read all my tips above.
  • Leftovers can be stored in a sealed container in the fridge for up to 3 days and reheated in the microwave, stovetop or instant pot.
