A homemade spice blend and killer marinade infuses flavor into thin cut steak for these fast and easy homemade steak fajitas made in the skillet.
Laurie McNamara’s blog Simply Scratch reminds us that no matter how busy life gets, sometimes we just need to slow down and take the time to cook a proper meal, like these onion and sweet bell pepper topped Steak Fajitas.
There’s simply nothing like a true homemade meal. Especially one void of preservatives and artificial ingredients, yet simple enough to entice all levels of home cooks.
Needless to say, when we found out she was publishing her first book, Simply Scratch: 120 Wholesome Homemade Recipes Made Easy we were thrilled, because this girl knows how to cook.
Her Skirt Steak Fajitas recipe at the bottom of this post was one of the first to catch our eye. And here’s why…
Simply Scratch Steak Fajitas
Laurie shares in her book that this steak fajitas recipe was one of her go-to, no-fail recipes in the early years of her marriage. Back then she used frozen, pre-cooked chicken strips and frozen fajita vegetables to get this on the table. Totally acceptable, but not really homemade.
These days, Laurie creates her fajitas from scratch, natch!
These homemade fajitas are absolutely incredible. I’ve never been one to order fajitas at my favorite Mexican joint (I’m more about the chili rellenos and enchiladas) but after tasting these, I am a certified fajita loving convert. At least in my own homemade kitchen.
We had leftovers after dinner and my husband put them to work the next morning when he made himself a version of a Machaca burrito. He chopped up the leftovers, scrambled them with egg and threw them in a tortilla with some cheddar cheese. Holy crap.
This is the way to leftover!
What’s in These Steak Fajitas?
The key to this dish’s amazing flavor is the incredibly flavorful and balanced homemade steak fajita seasoning Laurie shares in her book. Its combination of spice, salt, and heat infuses the meat in just 30 minutes for a surprisingly deep flavor in such a short amount of time. I can’t wait to try the mix with tacos, too.
In addition to the homemade steak fajita seasoning, you’ll need:
- Olive oil
- Fresh cilantro
- Skirt steak
- Sweet onion
- Kosher salt
- Bell peppers
- Flour tortillas
Freshly sliced peppers and onions are hallmarks of fajitas. Laurie recommends red and orange bell peppers. I of course added a few extra just because I am a huge fan of the veggie component of any dish.
How to Make Steak Fajitas
You’ll first need to whisk together the steak fajita marinade. It’s a simple combination of homemade steak fajita seasoning, olive oil, fresh garlic, and fresh cilantro. Whisk that all together and let the steak marinate for at least 30 minutes.
Then, heat a cast iron skillet over medium-high heat and melt the butter in it. Add the sliced onion and season it with kosher salt, and cook until the edges of the onion are a lovely golden color. Add the sliced bell peppers and continue cooking until they’ve reached your preferred texture.
Transfer the veggies to a separate dish, then sear the steak on both sides for roughly three to four minutes. Once seared, place the steak on a cutting board and slice into thin strips. Return the steak to the skillet (including any juices that have accumulated on the cutting board), squeeze a little lime juice over top, and continue cooking a few minutes longer.
I like to serve up my homemade fajitas with avocado that’s been mashed with kosher salt and lime juice, plus a sprinkle of Cotija cheese.
What’s the Best Steak for Fajitas?
Laurie’s original recipe calls for using skirt steak but skirt steak was a little difficult for me to find so instead I used hanger steak. Flank steak would also make a fine substitution but will cost you more at the register.
Do I Have to Use a Cast Iron Skillet?
No, but if you have a cast iron skillet you should definitely use it. The benefit of using cast iron is that it conducts heat evenly. If you don’t have a cast iron skillet, you can use a regular skillet.
Can I Add Other Veggies to the Fajitas?
Of course! Bell peppers and sweet onion are the traditional fajita vegetables, but you’re welcome to throw in anything you have on hand. It’s your kitchen, after all!
Can I Make These Steak Fajitas in Advance?
Homemade fajitas are best enjoyed right away as the steak loses its juiciness over time. However, if you have leftovers or you want to meal prep these fajitas, I recommend storing all the components separately and assembling the fajitas when you’re ready to eat them.
What to Serve with Steak Fajitas
Not sure what to serve with these homemade beef fajitas? Any Mexican side dish will go perfectly with them. A few of my favorite things to serve with these skirt steak fajitas are:
- Tortilla chips and Pico de Gallo
- Hatch Chile Salsa Verde
- Avocado Salsa Verde
- Southwest Quinoa and Grilled Corn Salad
- Rice and beans
- Mexican Coleslaw
Tips for Making the Best Steak Fajitas
Steak is the main protein in this homemade version of the popular Mexican dish, but Laurie assures us this recipe is equally as delicious with boneless, skinless chicken breast as well.
After you’ve seared the steak, let it rest on the cutting board for a good 5 to 8 minutes before slicing it. This gives the juices time to to redistribute throughout the meat and makes for better fajitas.
Finally, feel free to use corn tortillas instead of flour if you need to make this recipe gluten-free. Just keep in mind that corn tortillas crumble more easily than flour, so you may want to double up on them to hold the homemade fajita filling securely.
