The best part about the Instant Pot is that you can sauté right in the pot. This is awesome because you don’t have to get a separate pan dirty. Once the spice mixture is made it gets tossed with the thinly sliced steak and sautéed in the IP. Then all the remaining ingredients get added in and you cook for 7 minutes! It is really that easy. You get the most flavorful and tender steak and peppers to add to any meal.

Tips for this Recipe:

  • Use flank steak or sirloin steak – most other cuts of beef will be too tough
  • It seems like a very short time, but it really does cook in 7 minutes. The IP cooks meat much faster and you don’t want tough meat
  • The spice mixture isn’t spicy, so omit the jalapeño in the recipe if you don’t want any heat
  • There is some liquid left in the pot after it is done cooking, save that and store it with any leftover steak to keep it juicy and flavorful!

  1. Made this tonight to eat tomorrow. I like it but to me it doesn’t taste like fajitas…more like a beef vegetable stew…maybe with sour cream, salsa, pickled red onions, etc it will taste mexican.

  2. 1 star
    What did I do wrong? I had high hopes for this recipe but the meat was so tough I couldn’t even chew through it and the bell peppers were complete mush. Especially frustrating as it meant I had to find quick replacement dinner plans as this was a complete flop (and not a cheap one at that given the price of the meat).

    1. I am sorry to hear this Melissa. I have cooked this many times and never had this experience. Maybe the meat wasn’t sliced thin enough? I also know that some Instant Pots can come to pressure differently and cause different results.

  3. These Whole30 easy steak fajitas are best served up with a side of fried cauliflower rice or on top of a bed of zucchini noodles. In a small bowl, combine all of the marinade ingredients together using a whisk. Transfer the marinade to a gallon ziplock bag and add the flank steak.

      1. I have not made it with chicken and I test all of my recipes and cooking times for each protein very carefully, so I can’t tell you what those times would be. I have a One Pan Chicken Fajita Skillet on the blog as well if you are interested in trying that out.

    This recipe was fantastic. So flavorful and tasty. My husband went back to the instant pot looking for seconds but there wasn’t any. I also served it with some sour cream I had in the fridge and an extra sprinkling of cilantro on top at the end.

  5. 5 stars
    Just got an instant pot for Christmas and this was our first recipe! So easy, yet delicious. My husband went back for seconds AND we had leftovers for lunch. Thank you!

    1. Are the nutrition facts for just the steak or steak and guacamole together? It’s actually more carbs than I would’ve expected for this recipe.

      1. 5 stars
        The nutrition facts do include both the steak and guacamole. There is also a lot of fiber, so if you do net carbs, it would be 10 per serving. Hope that helps!

  6. Are the sliced jalapeños and diced red onion to go into the pot with the steak to cook, or are they meant to be used as fresh toppings after cooking is done?

    1. 5 stars
      There is both Jalapeño and red onion in with the steak and in the guacamole. It is listed under both ingredient and instruction sections. Hope that helps!

  7. 5 stars
    Love this recipe! Actually the first one I made using my instant pot. Will definitely make again in the future!
