Mexican food is my absolute favorite type of cuisine. It’s flavorful, quick to make, and a crowd-pleaser at my house! Fajitas, in particular, are a dish that I love to make (but mostly eat!), but cooking beef in the oven takes too long on a weeknight and it heats up the house (fine during winter, but awful during summer). Turn any night of the week into a fiesta with these easy Instant Pot Steak Fajitas!

Start by making the fajita spice mix. You may be used to just buying a packet of Old El Paso from the grocery store, but I promise that making your own is worth it! It’s super simple to make and you likely already have all the spices you need for it, so don’t cut this corner. Mix them all up and add the flank steak and some oil to the bowl. You may need to slice up the meat yourself, but if you buy it from a butcher, ask if they’ll cut it for you! Many butchers offer this service for free, which makes this recipe even more convenient.
Toss the meat until it’s covered in the seasonings. Then turn the Instant Pot to Saute mode and add about another tablespoon of oil once it’s hot. Add the meat and cook for about 5 minutes until browned on all sides. Remove from the pot and set aside.
Add the broth to deglaze the pot and release any stuck on bits of food. This is an important step to ensure that you don’t get the BURN notice when you pressure cook later on. Add the browned meat back to the pot followed by the soy sauce, apple cider vinegar, and lime juice. This will give the meat more flavor, but the ACV and lime will also help break down the proteins in the meat to make it more tender! Then lid the pot and cook on Manual/Pressure Cook HIGH for 7 minutes. Once the cook time has elapsed, allow for a 10-minute natural release to ensure the meat doesn’t become chewy.
Remove the lid and immediately add the onions and peppers. Give it a quick stir and re-lid the pot, closing the steam valve and keeping the Keep Warm setting on for another 10 minutes to soften the vegetables. this is the best way to make sure the pepper-onion mix doesn’t get soggy and maintains a little bit of crunch!
Time to serve! Using a slotted spoon, remove the contents of the pot. Add the fajita mixture to the wraps and top with salsa, sour cream, and avocado or guacamole! It’s fiesta time!
Our 6-quart Instant Pot Duo took 11 minutes to come to pressure, but the time will vary depending on the model and size you’re using.
For better flavor, marinate the steak up to 48 hours before cooking and simply store in an airtight container in the fridge.
