What You Need:
- Spice Mixture
- Chili Powder
- Salt
- Cumin
- Garlic Powder
- Onion Powder
- Coriander
- Flank Steak (or sirloin steak)
- Beef Broth
- Tomato Paste
- Red & Green Bell Peppers
- Garlic
- Jalapeno
- Red Onion

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!

Build Your Bowl:
- To keep it Paleo & Whole30, serve over lettuce and cauliflower rice. I love to use my Cilantro Lime Cauliflower Rice as a base. If not doing a round of Whole30, I love to make my Instant Pot Cilantro Lime Rice
- Add all your favorite Whole30 toppings!
- Sliced red onion
- Sliced jalapeno
- Cilantro
- Avocado
- Tomato
- Pico de Gallo
- Guacamole

Do you know around what size/weight flank steak you used for this recipe?
It is about 1 to 1.5 lbs of steak for this recipe, enjoy!
Love fajitas! So awesome to see so many delicious meals, gluten free!
Thank you Gracie!
Love this recipe! Actually the first one I made using my instant pot. Will definitely make again in the future!
SO happy to hear this! And yay for the first time using the Instant Pot!
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?
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!
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!
So happy to hear this Sarah, thank you for sharing 🙂
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.
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!
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.
Can we use chicken instead of steak?
I want to know this too! Hope we get a reply this year 🙂
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.
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.
This dinner looks amazing! I love the seasonings you chose for it.
