  • Easy prep: Marinate steak ahead, then assemble quickly before serving.

Ingredients You’ll Need

  • Flank steak (a single, thick cut for juicy slices)
  • Olive oil (for marinade richness and grilling)
  • Fresh limes (juice for tangy zip)
  • Canned chipotle peppers in adobo (smoky heat)
  • Garlic (crucial aromatic)
  • Cilantro (herbal freshness)
  • Green bell peppers and onions (sliced and sautéed for fajita flavor)
  • Tortilla chips (thick, sturdy chips preferred for topping the nachos)
  • Shredded cheese (Mexican blend, cheddar, or pepper jack)
  • Sour cream, salsa, guacamole (for topping and dipping)

Step-by-Step Instructions

1. Make the Chipotle Marinade

To start, blend olive oil, chipotle peppers (with a little adobo sauce), freshly squeezed lime juice, garlic, and cilantro in a blender or food processor until smooth and fully combined. This vibrant marinade infuses the steak with spicy, tangy, and herbaceous flavor.

  1. Add 1/3 cup olive oil, juice of 2 limes, 4 chipotle peppers in adobo, 3 garlic cloves, and a big handful of cilantro to a blender.
  2. Blend until the mixture is smooth, colorful, and aromatic.

2. Marinate the Flank Steak

Place a whole flank steak in a large resealable plastic bag. Pour the marinade over the steak, seal the bag, and squish to coat the meat evenly. Marinate in the fridge for at least 24 hours, or up to 36 hours for maximum flavor penetration.

  • Tip: The longer the steak sits, the deeper the flavor!

3. Grill or Sear the Flank Steak

Remove the marinated flank steak from the bag and grill over high heat for a few minutes a side, just until charred and cooked to your preferred doneness. Alternatively, sear in a hot skillet. Let the steak rest under foil before slicing thinly across the grain for tenderness.

4. Prepare the Fajita Veggies

Slice onions and green bell peppers into thin strips. Sauté them in a large skillet over high heat, just until softened and caramelized with seared, flavorful bits. Season lightly with salt, pepper, and a sprinkle of taco seasoning if desired for extra punch.

  1. Heat 1 tbsp olive oil in a skillet.
  2. Add 1 large sliced onion and 2 sliced green bell peppers.
  3. Cook over high heat until vegetables are tender and slightly charred.

5. Slice the Steak

Cut the rested flank steak in half lengthwise, then slice thinly across the grain. The resulting strips are juicy, boldly seasoned, and ready to crown your nachos.

6. Stack the Nachos

  1. Spread sturdy tortilla chips in a single layer on a large rimmed baking sheet, cast-iron pan, or oven-safe platter.
  2. Scatter sautéed peppers and onions over the chips.
  3. Add sliced steak on top of the veggies.
  4. Cover with a generous sprinkle of cheese: sharp cheddar, Mexican blend, or pepper jack all melt beautifully. Use enough to cover but not smother the other toppings.

Bake or broil briefly until the cheese is melted and bubbly—just a few minutes—then remove from the oven.

7. Add Final Toppings

  • A few dollops of sour cream
  • Fresh guacamole
  • Chunky salsa (mild or hot)
  • Chopped cilantro or scallions
  • Optional extras: sliced jalapeños, fresh avocado, diced tomatoes

Pro Tips and Variations

  • Make ahead: Marinate steak up to 2 days before, slice and refrigerate until ready. Sauté veggies in advance, then assemble right before serving.
  • Vegetarian version: Substitute steak with roasted mushrooms or black beans. Keep all the fajita spices for authentic flavor.
  • Extra smoky flavor: Grill veggies alongside the steak for authentic charred taste.
  • Serving style: Build individual nacho plates or assemble a huge party-sized platter.

Frequently Asked Questions (FAQ)

Q: How spicy are beef fajita nachos?

A: The chipotle peppers in the marinade provide medium heat. Adjust the number of peppers or add extra lime juice to tame the spice.

Q: Can I use another cut of beef?

Q: What’s the best cheese for nachos?

A: Mexican blend, sharp cheddar, and pepper jack melt well and complement Tex-Mex flavors. For authenticity, try a mix of cheeses.

Q: Are beef fajita nachos gluten-free?

A: Yes, as long as you use certified gluten-free tortilla chips and double-check spice blends and sauces.

Q: Can I prepare nachos ahead of time?

A: Prep steak and veggies ahead, but assemble and bake nachos just before serving to keep chips crisp.

Expert Tips for the Perfect Nachos

  • Layering is key: Spread out chips for even topping distribution. Don’t overload—every chip deserves flavor!
  • Cheese matters: Use freshly shredded cheese for best melt and stretchiness.
  • Marinade time: Overnight or longer for steak makes all the difference in texture and taste.
  • Veggie color: Use multiple pepper colors—green, red, and yellow—for eye-popping presentation and sweetness.
  • Quick broil: Watch closely under broiler so cheese melts and bubbles but chips don’t burn.
