Pico de Gallo: Adds freshness and acidity to balance the rich, savory elements.
Toppings: Guacamole, sour cream, and additional cilantro take these nachos from great to unforgettable.

Variations

Protein Swaps

Substitute chicken breast or thighs for the flank steak. Marinate and cook just as you would the steak. Alternatively, try shrimp for a seafood twist, adjusting cooking time to just 2-3 minutes.

Vegetarian Option

Skip the meat entirely and double up on peppers and onions. Add black beans or pinto beans tossed in a bit of the marinade for protein and substance.

Heat Level Adjustments

Spice lovers can add sliced jalapeños or a sprinkle of cayenne to the marinade. For a milder version, reduce the amount of green chiles or substitute with a mild salsa.

Cheese Choices

While Mexican blend works perfectly, try combinations of Monterey Jack, sharp cheddar, queso fresco, or pepper jack for different flavor profiles.

How to Make Skillet Steak Fajita Nachos

Step 1: Prepare the Marinade

Combine olive oil, taco seasoning, lime juice, green chiles, cilantro, and garlic in a blender. Pulse until smooth and well incorporated. The marinade should have a vibrant green color and smell absolutely incredible.

Step 2: Marinate the Steak

Place your flank steak in a ziplock bag and pour in most of the marinade, reserving about 2 tablespoons for the vegetables. Seal the bag, removing as much air as possible, and massage the marinade into the meat. Refrigerate for at least 24 hours, turning occasionally to ensure even flavor distribution.

Step 3: Cook the Steak

Heat a large cast iron skillet over high heat until smoking hot. Remove the steak from marinade, letting excess drip off. Cook for 4-6 minutes per side for medium-rare to medium doneness. Transfer to a cutting board and let rest for 5 minutes before slicing into bite-sized pieces against the grain.

Step 4: Sauté the Vegetables

In the same skillet (don’t clean it!), add the chopped bell peppers and onions along with the reserved marinade. Sauté for 3-5 minutes until the vegetables are tender but still have some bite. The onions should be translucent but not completely soft. Transfer to a plate.

Step 5: Assemble and Melt

Reduce heat to medium and add a layer of tortilla chips to the skillet. Sprinkle half the cheese over the chips, then layer on the sautéed vegetables, steak pieces, and remaining cheese. Top with fresh pico de gallo and additional cilantro.

Step 6: Finish and Serve

Either continue cooking on the stovetop until cheese is melted, or place under a broiler for 4-6 minutes until bubbly and lightly browned. Serve immediately with guacamole, sour cream, and extra pico de gallo on the side.

Pro Tips for Making the Recipe

Slice Against the Grain: Always cut flank steak against the grain for maximum tenderness.
Don’t Overcrowd: If cooking for a crowd, make two skillets instead of piling too high in one pan. This ensures even melting and prevents soggy chips.
Marinade Magic: Don’t rush the marinating time. Those 24 hours make a tremendous difference in flavor.
Layer Strategically: Put cheese both under and over the toppings to create a “glue” that holds everything together.
Keep Toppings Ready: Have all your cold toppings prepared before cooking so you can serve immediately while everything is hot.

How to Serve

These nachos make for a stunning presentation right in the skillet. Bring it to the table and let everyone dig in!

Perfect Pairings

Serve alongside ice-cold Mexican beer, margaritas, or agua fresca for an authentic experience.

Make it a Meal

Although these nachos can be a meal on their own, they also pair wonderfully with a simple side salad dressed in lime vinaigrette.

Topping Bar

Set up a nacho bar with additional toppings like sliced jalapeños, black olives, corn, black beans, and different salsas so everyone can customize their portion.

Make Ahead and Storage

Prep Components Ahead

Marinate the steak, chop vegetables, and prepare toppings up to a day in advance to make assembly quick and easy.

Storing Leftovers

Leftover nachos can be stored in an airtight container in the refrigerator for up to 2 days, though the chips will soften over time.

Reheating

For best results, reheat nachos in a 350°F oven for 5-7 minutes until warmed through. Avoid microwaving as this will make the chips soggy.

Component Storage

If you have leftover steak and vegetables, store them separately from the chips. They can be used for tacos, quesadillas, or a fresh batch of nachos later.

FAQs

Can I use a different cut of beef for these nachos?
Absolutely! Skirt steak works wonderfully as an alternative to flank steak, with similar cooking times. Ribeye or sirloin can also be used for a more tender result, though they’re typically more expensive. Just adjust cooking time according to thickness and desired doneness.

How can I prevent my nachos from getting soggy?
The key to crispy nachos is using thick, sturdy tortilla chips, adding the toppings just before serving, and not overloading with wet ingredients. If you’re worried about sogginess, you can also briefly toast the chips in the oven before adding toppings.

Can I make these nachos on a sheet pan instead of a skillet?
Definitely! A sheet pan works great for feeding a larger crowd. Follow the same instructions but assemble on a parchment-lined baking sheet and bake at 400°F for about 5-7 minutes until the cheese is melted. You’ll miss some of the skillet’s charred flavor, but the convenience might be worth it.

Is there a way to make this recipe quicker if I don’t have 24 hours to marinate?
While the full marinating time gives the best flavor, you can still get good results with a minimum of 4 hours. For an even quicker option, use a vacuum sealer if you have one – this can reduce marinating time to about 2 hours by forcing the marinade into the meat more quickly.
