Skip the smoking skillet and effortlessly make delicious Instant Pot Steak Fajitas using an inexpensive cut of beef and the Instant Pot.

Fajitas in the Instant Pot?

Fajitas are classically made on a searing hot skillet with thin strips of meat, peppers, and onions.

However, we can skip the smoking skillet (and the smell that comes with it) and make delicious steak fajitas using the instant pot.

The advantage of making steak fajitas using an electric pressure cooker is that you can use a less expensive cut of meat and still have delicious results!

Notes on Ingredients

• Steak: For the meat, you can use sirloin or flank steak. Keep in mind sirloin is often less expensive and easier to find.
• Peppers: Use any combination of bell peppers you like–red, yellow, and/or green. I personally love using a variety of colors for visual pop. Plus red and yellow peppers add a sweeter flavor, while a green bell pepper adds a nice fresh flavor.
• Onion: Use a yellow, white, or sweet large onion for fajitas. I don’t recommend red onions for this recipe, as they don’t get as tender as white onions when pressure cooked.
• Beef Broth: Use low-sodium beef broth for the thin cooking liquid. For this recipe, you will only need to use ½ cup for a 3 or 6-quart instant pot or ¾ cup for an 8-quart model. As you may know from my Instant Pot Basics, you need at least 1 cup of liquid to cook in a pressure cooker. HOWEVER, the juice that the raw onions and peppers release will provide enough liquid to cook these Steak Fajitas.
• Fajita Seasoning: I use my homemade blend of fajita seasoning which is made with smoked paprika, garlic powder, onion powder, and cumin. You can use store-bought seasoning or even taco seasoning to flavor these fajitas.
• Limes: Do not overlook this addition! Adding both the juice and zest of fresh limes will brighten up all the flavors of the fajitas, and the acid from the lime juice will make the flavors pop in your mouth.

How to Make Instant Pot Steak Fajitas

• Place your sirloin or flank steak into the freezer for 10 to 15 minutes, as this will make it much easier to thinly slice.
• After freezing, slice the steak into ½-inch strips going against the grain.

• Turn the Instant Pot to saute, add in a bit of oil and let it heat.
• While the oil is heating, toss the sliced steak with fajita seasoning to coat.
• Once the oil is heated, add about half the seasoned meat to the Instant Pot in a single layer. You don’t want to overlap the meat, or you won’t get nice caramelized edges on the beef.
• Saute the strip of steak for 1-2 minutes per side, to JUST brown.
• Once the meat is seared on both sides, remove the steak from the inner pot and place it on a plate.
• Repeat the process with the remaining meat, adding in an additional teaspoon of oil if needed.

• Turn off the saute function and add the beef broth to the inner pot and scrape, scrape, scrape all the browned bits off the bottom of the inner pot. That will prevent a burn notice from occurring and help to flavor the fajitas.
• Add the seared steak back to the inner pot and top with the sliced onion and peppers.
• Sprinkle the peppers and onions with a bit more fajita seasoning for additional flavor.

• Place the lid on the Instant Pot and be sure the venting knob is pointed to sealed.
• To set the cooking time, hit Manual or Pressure Cook and set to cook on high pressure for 2 minutes.
• Once the cooking time has elapsed, let pressure release for at least 10 minutes, which will keep the meat super tender.

• Remove the steak and pepper mixture to a serving bowl, using a slotted spoon.
• Add the lime zest and juice to the fajita mixture and stir to incorporate.

Serving Suggestions

Serve this steak fajita mixture on warmed corn or flour tortillas. Top the mixture as desired, with sour cream, shredded cheese, sliced avocado, and/or minced cilantro.
