    Why You'll Love This Recipe

    Skillet Steak Fajita Nachos are one of my favorite recipes to make when I'm craving Mexican food. It really is the ultimate nacho dish!

    Nachos are easy to make and totally customizable! Plus, this recipe is dairy-free, gluten-free, and can easily be made grain-free by using Siete Chips. The whole family is sure to love this flavorful dish!

    What are Steak Fajita Nachos?

    Nachos are a popular game day appetizer made by baking corn chips with cheese on top. You can also add a variety of toppings!

    For this recipe I topped the crispy chips with marinated steak, caramelized onions, and sweet bell peppers. My favorite toppings are freshly chopped cilantro, guacamole, and salsa.

    Do I Need Cheese?

    I opted to not use cheese, but this recipe would be great with cheddar cheese or any shredded cheese.

    I love Miyokos dairy-free cheese! Sprinkle plenty of cheese on top and pop the tray in the oven at 350 degrees for a few minutes to melt the cheese before serving.

    🍴Ingredient Notes

    Ingredients measured out for steak fajita nachos.
    • Steak - You can use a few different cuts of beef with this recipe. Any thin, flat steak like flatiron steak, flank steak, or skirt steak will work.
    • Olive Oil - To cook the steak and vegetables I suggest using a little olive oil, avocado oil, or coconut oil.
    • Homemade Fajita Seasoning - You'll need chili powder, garlic powder, salt, paprika, cumin, and cayenne pepper. To save time, you could use a taco seasoning packet instead.
    • Bell Peppers - I find that yellow, orange, and red bell peppers are the most flavorful, but green bell peppers will work too!
    • Chips - For a grain free option, use Siete Tortilla Chips made with cassava flour. Corn chips work great too! (They're also a little sturdier.)
    • Guacamole - Any homemade or store-bought guacamole will work or swap for cubed avocado or mashed avocado.
    • Salsa - Traditional salsa or pico de gallo are great toppings for this recipe.
    • Chopped Cilantro - I love adding in freshly chopped cilantro on top, but it's not necessary.
    • Red Onion - I love using red onion, but you can also use sweet onions with fajitas! A combination of both onions is great too.

    Topping Ideas

    • Salsa or Pico De Gallo
    • Dairy-Free Sour Cream
    • Mashed Avocado
    • Cubed Avocado
    • Dairy-Free Cheese
    • Black Beans
    • Diced Jalapeños
    • Lime Wedges

    🍴Step by Step Instructions

    Step 1: Seasoning the Steak

    Start by adding the steak into a large bowl with olive oil and spices. Stir together until the steak is evenly coated. Place in the refrigerator to marinate while you prepare the vegetables.

    Step 2: Cooking the Steak

    To cook the steak, place it on a preheated cast iron skillet or any large skillet. Cook on medium-high heat for about 2 minutes on each side. Remove from the pan and let rest.

    Expert Tips

    • To avoid soggy leftovers, keep everything separate. Let guests make their own nacho plates by keeping the chips, fajita mixture, and toppings in bowls on the side.
    • Do not overcook the steak. It's very thin and will continue cooking while it rests. If it's too rare, bake the nacho tray for a few minutes or add the steak back into the skillet.
    • For toasted chips, place tortilla chips in the oven at 375 degrees for a few minutes or until the chips are golden brown.
    • Cut the steak into bite sized strips so it's easier to enjoy this recipe.

    Frequently Asked Questions

    What should I serve with Fajita Steak Nachos?

    This dish goes well with Mexican rice, Cilantro Rice, or refried beans. (I love Siete Foods Refried Beans!)

    It would also be delicious with a side of my Mexican Street Corn recipe.

    What kind of steak is used with fajitas?

    Any flat steak like skirt steak, flatiron steak, or flank steak works great.

    Should I cut the steak before cooking fajitas?

    The short answer is no. I would cook the steak as is to avoid overcooking and keep it juicy! Cut the cooked steak into thin slices before adding on top of the nachos.

    Can I grill the Fajita Steak?

    You can grill the fajita steak on an outdoor grill or an indoor grill pan.

    How to store leftovers

    Leftovers should be stored in an airtight container in the refrigerator for 2-3 days.

    The chips will get soggy under the juicy steak and vegetables, but if you use an air fryer to reheat them it works great! You could also try broiling them on low in the oven for a few minutes.
