These easy Beef Fajitas made with flank steak, bell peppers, red onions, and our homemade fajita seasoning come together in no time and couldn't be more delicious. In less than thirty minutes, you can have restaurant quality fajitas on the table for a healthy, family friendly dinner.
There is nothing I love more than an easy sheet pan dinner that has my whole family asking for seconds. These sheet pan steak fajitas are exactly that. The process from start to finish couldn't be easier. Slice up some steak, bell peppers, and red onions. Add lime juice and fajita seasoning. Spread everything out on a sheet pan. Wait 15 minutes and dinner is done.
While the steak cooks, you can make some quick side dishes. Heat up some flour or corn tortillas. Warm up a can of refried beans or black beans. Slice up some avocados, cilantro, and lettuce. Grab a bag of shredded cheese, sour cream, and some store bought pico de gallo or salsa. That's all you need for a meal that seriously tastes like it came from a restaurant.
Lay it all out on the table and let everyone build their own fajitas. It's fun, it's healthy, and it is always a crowd-pleaser. One more idea for those looking for something a little untraditional. These steak fajitas can be used to make rice bowls (with regular or cauliflower rice), salads, quesadillas, burritos, and even taste amazing wrapped up in lettuce for a low carb treat.
What cut of beef is best for fajitas?
When making fajitas, I like flank steak since it is lean, stays tender, and is easy to find and work with. However, you can also use skirt steak, sirloin steak, or rump steak as well to make fajitas. For all of these steak choices, make sure to slice it thin and against the grain. This helps it to stay tender. You can also use more expensive cuts, really anything will work.
Traditionally, fajitas were made with "faja" steak, which refers to skirt steak, which comes from the belt or girdle of the cow. It was a dish made by Mexican ranchers on the border of Mexico and Texas.
What to serve with steak fajitas?
These fajitas are a meal on their own with some warm tortillas and toppings. However, around our home, the more toppings and side dishes the better. Here are some favorites:
- Start traditional with warmed flour tortillas, shredded lettuce, pico de gallo, limes, and shredded cheese.
- Kick things up a notch with some sliced avocado or guacamole.
- Add fiber to the meal with some quick refried beans or black beans. I like to top mine with some pico de gallo and melted cheese.
- For something light and fresh, consider making this Cucumber, Avocado, and Tomato Salad or Creamy Mexican Coleslaw.
- During summer months, I love serving this with some grilled corn or Mexican Street Corn Salad.
Can I add other veggies to the fajitas?
Many people like to kick up the veggies in this recipe or substitute in other vegetables if they can't eat bell peppers or onions. The main thing to keep in mind when adding extra vegetables or swapping in vegetables is that you want something that cooks quickly. Some favorites include zucchini, summer squash, thinly sliced carrots, fresh corn, thinly sliced butternut squash, and cauliflower.
The other thing to remember is that you don't want to overcrowd the pan. If you are adding lots of extra veggies, you may need to use two sheet pans to make sure the meat and vegetables aren't piled up on the sheet pan. You want a single layer for the best results.
