I use this same recipe for either my steak taco’s or my steak fajitas.  The peppers and onions came out extra delicious cooking in the sous vide bag.  

 I have a delicious Instant Pot Southwestern Quinoa Black Bean Salad that pairs wonderfully with these steak fajitas as well as the instant pot chicken fajitas if you prefer chicken over steak.  The salad is a lovely mix of quinoa, black beans, corn, a tangy dressing & prepared in less than 15 minutes in your instant pot.

What Is Sous Vide Anyway

If you are scratching your head wondering what is Sous Vide exactly.. let me help. Sous Vide is a way to cook that uses the process of sealing up food in an airtight vacuum sealed bag. Then you cook the food in temperature-controlled water (Instant Pot). This process is becoming so popular and for good reason. 

What Are The Benefits of Sous Vide 

Sous vide offers benefits and also is known to enhance the food. The reason why Sous Vide is popular is that it is a way to enhance the flavor of your recipes without adding in salt or fat to gain flavor. The sealing vacuumed bag helps soak in vitamins, minerals and more. They are not lost in the cooking process like other cooking methods. 

Is Sous Vide Steak Better 

Sous vide steak to me is better quality. The reason I say this is it helps to tenderize the steak so that it is incredibly tender. If you like super tender and juicy steak I highly recommend trying the sous vide method. 

What Goes With Steak Fajitas 

Traditional steak fajitas are generally served with a stack of tortillas, refried beans, Mexican, rice or even the classic side of guacamole or pico de gallo. I like to add a dollop of sour cream on top of mine, and it tastes fantastic. 

 How To Store Leftover Instant Pot Steak Fajitas 

You can take any leftovers you have and place them in an airtight container. Then store in the fridge for up to three days. 

Best Way To Reheat Fajitas 

I like to warm them up in a skillet. If you find that you need to add some liquid to the mixture to help it from drying out, use stock or even a little water. Then warm over medium-low heat until warmed through.

I just toss some tortillas wrapped in aluminum foil in the oven and let them warm up, and then serve it up. My family is never sad if we eat this leftover. 

Best Peppers For Fajitas 

I reach for bell peppers. You can use any color you want, or opt to do a handful of colors so you add in more flavor. I also use a yellow onion a lot or white to pair next to the mild peppers.

Using my sous vide made this meat the most flavorful, tender meat ever! Which is exactly what I want when I am biting into a delicious fajita. 


  • 1 flank steak, approximately 24 oz.
  • Juice of 1 lime
  • 2 cloves of garlic, finely chopped
  • 2 tablespoon olive oil
  • 1.5 tablespoon chili powder
  • 2 teaspoon ground cumin
  • 1 teaspoon salt
  • 1 teaspoon paprika
  • 1/4 to 1/2 teaspoon cayenne powder, depending on heat desired
  • 1/4 teaspoon black pepper
  • Small bunch of cilantro
  • 2 each, red and green peppers
  • 2 medium onions or 1 large
  • 2 tablespoon olive oil
  • 1/2 - 3/4 c. Chicken broth, if required
  • Flour tortillas
  • 2 avocados
  • 1 lime
  • Optional- sour cream


  1. Preheat your Instant Pot Ultra or immersion circulator to 135F

For the flank steak:

  1. Combine all spices, olive oil, garlic, and lime juice in a small bowl.
  2. Pour this mixture into a Sous vide bag.
  3. Add the steak, turning it in the bag several times to thoroughly coat.
  4. Lay the cilantro across the top of the steak, and seal the bag. It’s important here to remove as much air as possible. Vacuum sealing is preferred, but not necessary as you can also use the water displacement method. To do this, slowly lower the bag into water, keeping the open top above the surface. The water pressure will force the air out of the bag, allowing you to seal it once removed.

For the peppers and onions:

  1. Slice the peppers into strips.
  2. Halve the onions, and cut to similar size as the pepper strips, breaking apart any larger chunks that stick together.
  3. Toss the veggie strips in a large bowl with the olive oil, add to another Sous vide bag, and seal. For this step more than with the steak, vacuum sealing is preferred. If that isn’t an option, you can add a scant 1/2 to 3/4 cup of chicken broth to the veggies, allowing you to use the water displacement method to effectively remove the air.

Submerge both bags in the Instant Pot, close the lid, and set for 2 hours.

  1. Just before done, preheat your broiler. Once finished, carefully remove both bags and pat dry. Using a broiler pan, or similar sheet, cut open the veggies -discarding the broth if used -and spread them evenly over the pan, leaving room for the steak. Remove the steak, discard the cilantro, and place next to the veggies. Broil for approximately 2-4 minutes or until just starting to brown and char, turn the steak, mix the veggies with tongs, and broil for another couple minutes.
  2. Transfer the steak to a cutting board and let rest for 5 minutes, then slice thinly against the grain.
  3. Serve on warm flour tortillas with the peppers and onions, accompanied by avocado slices, and fresh lime wedges for squeezing.
