Grilled Steak Fajitas
Does anyone else love fajitas? I’m all about any dish that comes out sizzling hot when you order it at a restaurant. Not only is it full for great flavor, but it’s relatively light and I don’t feel weighted down while I’m eating it.
I figured a good steak fajita recipe was in order, and it seemed like a natural fit with this dump recipe series. And June seemed like an even better time to share this, since I knew I wanted this month’s dump week to be grilling themed! Let me just say, this steak fajita marinade is a total winner! All you’ll need is a few ingredients and and a plastic zipper bag.
Tips for making Beef Fajitas on the grill
- I cut the veggies larger to make it easier to grill them and then slice after grilling.
- Pull the marinated beef and veggies out of the fridge 20 minutes before you intend to cook it, to help it get a little closer to room temperature.
- Before preheating the grill, spray it with nonstick cooking spray to avoid sticking.
- Use a meat thermometer to get it to the temperature for the level of doneness you’re looking for (I like to cook to 140 degrees for medium-rare).
- Rest the meat for 10 minutes before carving to allow for crossover cooking and for the juices to redistribute.
- Be sure to carve against the grain and try to slice the meat thin for easier eating.
What cut of beef is best for fajitas?
I like to use flank steak for this recipe. You can also use skirt steak or if those aren’t available, sirloin steak (just be sure to marinate it longer).
How do you slice the vegetables so they don’t fall through the grill grates?
I slice the onions into rings but I don’t separate the rings. For the peppers, I slice off the top and dispose of it as well as the seeds. Them I slice off the bottom and keep it whole and slice off each of the sides and keep them whole. That way, they’re flat chunks that you can easily rest on the grill grates without them slipping through. Once they’re cooked and have cooled a bit, I slice them into thinner slices for the fajitas.
What goes into the flank steak marinade?
I tried to keep things simple but still flavorful so for this marinade, I use a mixture of fajita seasoning, lime juice, olive oil and salt.
What is the difference between taco seasoning and fajita seasoning?
Taco seasoning tends to have a bit of a bolder flavor with a higher amount of chili powder and a few additional ingredients. Fajita seasoning is more subtle, which allows the beef flavor to truly shine through.
How long do you marinate the flank steak?
The optimal amount of time for a cut of beef to marinate is 12 to 24 hours. Anything longer than this can adversely affect the texture.
How long do these last?
Grilled flank steak is best served right away. That said, you can reheat these in a pan or in the microwave. They will last covered in the refrigerator for around 3 days.
Can you freeze steak fajitas?
I would encourage you to freeze the raw beef and veggies in the marinade before cooking. They will last for up to 3 months.
