Instant Pot Steak Fajitas are full of flavor and made incredibly easy thanks to the pressure cooker. These flavorful, tender instant pot fajitas are so incredibly easy to make and so delicious they are absolutely irresistible!
Instant Pot Steak Fajitas are one of the easiest, tastiest, and economical ways to make Steak Fajitas.
Steak Fajitas are typically made with grilled strips of steak, peppers, and onions and are especially delicious.
The advantage of making steak fajitas in the pressure cooker is that you can use less expensive cuts of meat and still have delicious results! Plus the process of making steak fajitas in the instant pot is a whole lot easier than grilling fajitas--this recipe for fajitas is almost completely hands-off.
Meat for Steak Fajitas
Skirt steak is what is typically used for traditional fajitas. However, the Instant Pot would overcook the skirt steak. Tougher cuts of meat lend themselves better to being cooked in the pressure cooker--which makes this recipe more affordable.
Choose one of the following cuts of meat:
- Sirloin Steak
- Top Round Steak
- Flank Steak
My favorite is sirloin or flank steak for these fajitas!
How to Make Instant Pot Steak Fajitas
Step One: Thinly Slice Beef
- Slice the cut of beef into thin strips against the grain of the meat. PRO-TIP: if you find it difficult to cut fresh beef, place in freezer for 10 minutes prior to slicing.
Step Two: Season Meat
- Toss meat with Homemade Fajita Seasoning
Step Three: Add Ingredients to Instant Pot
- Place steak in the pressure cooker.
- Add in beef stock (or water or beer).
- Place 1 bag of frozen pepper strips on top of the beef.
Step Four: Pressure Cook Steak Fajitas
- Place lid on the pressure cooker and be sure that vent knob is pointed to sealed.
- Hit Manual or Pressure Cooker and cook on high pressure for 5 minutes.
- Once cook time has elapsed, let pressure release for at least 10 minutes, before doing a quick release of any remaining pressure.
- Add zest and juice of a lime to fajita mixture and mix well.
Step Five: Serve Steak Fajitas
- Serve the fajita meat using a slotted spoon to drain off excess liquid before adding to tortillas.
- Top with guacamole, sour cream, cheese, cilantro, as desired.
A Few Notes on Pressure Cooker Fajitas:
- Steak Fajita meat will keep in the refrigerator for 3-4 days and freeze for up to 3 months.
- I only add in ½ cup extra cooking liquid. As you know from my Instant Pot Basics, you need at least 1 cup of liquid to cook in a pressure cooker. HOWEVER, the juice from the onions and peppers, along with the ½ cup extra added liquid will provide more than enough liquid to cook these Steak Fajitas.
- I use a bag of FROZEN pepper and onion strips because it makes these Instant Pot Steak Fajitas super easy and more economical in winter months when peppers are not in season. You can certainly use fresh onions and peppers if you would like. I would use 2-3 fresh peppers (any color) and 1 large onion cut into strips and saute in the Instant Pot on the saute function in 1 tablespoon oil until soft and tender. Then add in the remaining ingredients and proceed with the recipes.
- Feel free to use water or beer in place in beef stock for the additional added liquid.
- If you want to use FROZEN steak strips, increase the cooking time to 9 minutes instead of 5 minutes.
