Steak Fajita Recipe
Slow Cooker Fajitas are the perfect way to enjoy a restaurant quality dinner without the price tag…or all the work!
One of my favorite things about a slow cooker dinner is dumping it in and walking away until dinner is ready.
But why slow cook the steak? Cooking your steak fajitas in a slow cooker allows the steak to slowly soak up all the flavors for hours. You will be so happy you did because they will come out so juicy!
If you are having a busy weeknight, cooking for a crowd, looking to meal prep…or just looking for a great dinner minus the effort, then this fajita recipe is for you.
Steak Fajita Ingredients
With just a handful of pantry staple ingredients and fresh ingredients, you can whip up the most incredible (and juicy) steak fajitas!
For The Fajitas
Meat: To make true steak fajitas you will need skirt steak.
From the garden: Bell peppers, white onion, garlic cloves, and fresh cilantro.
The bell peppers can be any color, you don’t have to stick to just one! In fact, mixing colors can bring a lot of beauty to the dish.
For The Steak Marinade
This is where all those incredible flavors we know and love come into play with this dish.
Herbs and spices: Cayenne pepper, garlic powder, chili powder, kosher salt, paprika, onion powder, and ground cumin.
For cooking: Olive oil
How to Make Slow Cooker Fajita’s
1. Marinate the steak. Combine all the steak marinade ingredients in a medium mixing bowl. Marinate the steak for 30 minutes.
2. Cook the fajitas. Place the peppers, onions, garlic, cilantro, and marinated steak (with the marinade) in the slow cooker and cook on low for 8 hours or high for 4 hours.
3. Broil the steak. Transfer the steak from the slow cooker to a sheet pan and broil for 4-5 minutes, until it begins to char. Slice thinly and return to the slow cooker to toss in the juices.
4. Serve the fajitas. Serve the fajitas over warm tortillas or over rice.

Questions you may have
Slow cooking your meat is super important if you are looking to avoid chewy meat.
When you cook your meat slow and low it allows the meat to soak in all the flavors and come out super tender, juicy, and melt in your mouth perfect!
Taco seasoning and fajita seasoning are actually quite similar, but there are some differences.
Fajita seasoning has garlic powder and onion powder and taco seasoning does not. Taco seasoning also has something fajita season doesn’t not and that is ground coriander.
Albeit very similar in ingredients and flavor, there is a difference between the two.
Carne asada and fajitas are both thinly sliced beef and have both been marinated. However, the main difference is carne asada is not served with grilled onions and peppers.
There are 2 reasons why your fajita meat may be tough…
1. You cooked the meat at too high of a temperature and too fast.
2. You may have cut your meat incorrectly.
For tender meat, make sure to cut your fajitas across the grain.
The marinade! You do not want to skip out on steak fajitas marinade; this adds more flavor and makes it super tender.
I know what you are thinking, “how does that work?” The acid in the marinade breaks down the muscle and proteins in the meat before cooking leaving you with super tender and juicy fajitas!
You can also salt your steak with kosher salt the night before placing it in the marinade to tenderize it even more.

Nope! You can leave it in there for the same amount of time 🙂
Is the nutrition info for the entire thing, or what’s the serving size? Can’t wait to make this for meal prep!!!
It’s per serving and there are two servings in the recipe. If you’re tracking calories, I suggest using whatever you normally use to track in order to stay consistent and because this is a nutrition calculator that is mostly just an estimate.
