Ingredients You Need To Make This Crockpot Steak Fajita Recipe

crockpot steak fajita recipe

2 Pounds of Sliced Beef
For the beef, I went with sliced strips of flank steak. If that’s not you’re jam, or you don’t have any on hand, feel free to use sirloin, flat iron steak, or chuck or rump roast, And if red meat isn’t your thing, you can substitute it with chicken!

2 Bell Sliced Peppers
As far as the veggies are concerned, I typically mix it up with red and green bell peppers, but again, this is up to you. Use whatever color bell pepper you please (or can find at the store or in your fridge!) And as for the onion? I like the flavor of red onion, but sometimes it comes on too strong – so if you’re more of a yellow or white onion fan – go for it!

1 Large Sliced Onion
15 Ounces Diced Tomatoes
2 Tablespoons Fajita Seasoning (store-bought or homemade)
1 Tablespoon of Oil (if you’re going the Instant Pot route)
1/4 Cup Beef Broth or Water (if you’re going the Instant Pot route)

A Note About The Fajita Seasoning (Or This Mama Don’t Preach)

Ok, so I know there are some super important debates going down about the benefits of using homemade seasonings versus store-bought. And if you are detecting a little sarcasm here, then you feel me. Look, while it is true that homemade condiments have fewer preservatives and questionable ingredients than store-bought varieties, it is also true that sometimes ain’t nobody got time for DIY-ing their seasonings. So, you’ll get no Judge Judy action from me no matter which route you choose. But, full disclosure, if you with homemade, this recipe is technically over five ingredients – so know that on the front end – and please do not send me hate mail for lying.

The tea on the homemade version: I bet you have all these in your pantry. And, this makes right around 2.5 tablespoons worth – or the equivalent of one packet of McCormick or insert your favorite brand name here. All you have to do is add the ingredients to a bowl or a mason jar and stir them together!

Serving Ideas

The good news is you have several options for serving these steak fajitas. My kids like them over rice – and since we are trying to be gluten-free, cauliflower rice works best. But you can also go with white or brown rice. I love a lettuce wrap or cup – as long as I’m not wearing a white shirt:

Toppings

Top with sour cream, salsa, shredded cheese, sliced avocados and black olives.
