    Steak Fajitas

    Steak fajitas are classic West Texas and Northern Mexican dishes consisting of marinated and roasted beef that is thinly sliced and served with roasted peppers and onions. It is commonly served on a flour tortilla and is often accompanied by salsa, guacamole, rice, and re-fried beans.

    This style of fajitas is the same one you see being served at Mexican restaurants on the hot cast-iron plate. These are very simple to prepare and can be customized to your liking, including the marinade. Now you can bring your favorite restaurant steak fajitas right to your kitchen with this delicious recipe.

    Ingredients and Substitutions

    steak fajitas ingredients
    • Steak – It’s traditional to use either flank steak or skirt steak for this.
    • Spices – I used my Mexican Spice Blend for this.
    • Acid – A combination of lemon and lime zest and juice will help tenderize and flavor the meat.
    • Oil – You can use olive or avocado oil.
    • Tortillas Flour tortillas are the standard tortilla that is used in fajitas.
    • Peppers – I like to use a combination of red and yellow bell peppers along with poblano peppers. You can use all red or yellow peppers. In addition, you can use green peppers but I find their flavors to be inferior to red or yellow.
    • Onions – A yellow, white, sweet, or red onion can be used.

    How to Make Steak Fajitas from Scratch

    In a bowl, whisk together the lime zest, lime juice, lemon zest, lemon juice, olive oil, and 4-5 tablespoons of the Mexican spice blend until combined. Be sure to taste it to make sure it is very flavorful.

    making a marinade

    Next, transfer the marinade to a plastic bag along with the flank or skirt steak and mix until thoroughly combined. Place in the refrigerator for 24-48 hours.

    marinating flank steak

    After marinating, add 3 tablespoons of olive oil to a large 12” cast-iron, stainless steel, or non-stick skillet over medium-high heat.

    adding oil to a pan

    Do not wait for the oil to heat up. Immediately add in the steak and cook it for 3 minutes untouched.

    Next, turn the heat down to medium and move it around the pan for 1 minute or until browned.

    Flip the steak over and cook it for 3 to 4 minutes to achieve a medium-rare internal temperature.

    Set the steak aside and squeeze the juice of ½ lime over it. Let it rest for 3 to 4 minutes.

    adding lime juice to flank steak

    Discard the oil from the pan and return it to the cooktop over high heat and add 2 tablespoons of olive oil.

    adding more oil to a pan

    Once smoking, add in the peppers and onions and sauté for 3 to 4 minutes or until lightly browned but still firm.

    Make-Ahead and Storage

    Make-Ahead: This is meant to be eaten as soon as it is done cooking. If you prefer that the flank steak is more on the well-done side of things, you can keep it warm in a pan covered and in the oven at 200° for up to 30 minutes before serving.

    How to Store: Cover and keep it in the refrigerator for 3 to 4 days. The steak will freeze well, but the peppers and onions will not. Keep the steak covered and in the freezer for up to 3 months. Thaw it in the refrigerator for 1 day before reheating.

    How to Reheat: Add a small amount of oil to a large frying pan over high heat. As soon as it begins to smoke, lightly add in the steak, peppers, and onions and sauté for 2 to 3 minutes or until hot. When reheating steak cooked to a specific internal temperature, it will continue cooking and push it past the point of your original desired temperature.

    Chef Notes + Tips

    • Feel free to cook the steak to your desired internal temperature.
    • If you like spice, add a seeded jalapeño to the marinade.
    • The longer the steak marinades, the better.
    • Get all the current beef prices at US Foods.
    • Try a marinade consisting of ½ fresh diced yellow onion, 3 finely minced garlic cloves, 1 finely minced jalapeño, juice and zest of 2 limes, 1 tablespoon of coarse salt, and ½ cup of olive or avocado oil.  
    • I keep the steak whole while cooking it so that I can regulate the internal temperature.
    • The reason I don’t heat up the pan before cooking the steak is to control the heat, ensuring the spices don’t scorch the steak while cooking it.
