Step-by-Step Instructions

1
Preheat your Blackstone flat-top griddle over medium-high heat until the cast-iron surface reaches 400°F–425°F (205°C–218°C).
2
Apply a thin layer of high-smoke-point avocado oil across the cooking zone and set up a cooler 325°F warming zone on one side.
3
Place skirt steak strips directly onto the hot steel without moving for 2–3 minutes to build a deep golden Maillard crust.
4
Flip with a heavy beveled griddle spatula, add poblano peppers, white onion, and lime juice, and cook for 7 minutes.
5
Finish with flour tortillas, dome-steam for 30 seconds if melting cheese, and transfer immediately to warm plates.

💡 Chef Tips for Best Results

  • ✓Keep a squeeze bottle of water and a melting dome next to your Blackstone to steam vegetables or melt cheese in seconds.
  • ✓Always scrape food residue into the rear grease trap while the griddle is still warm, then rub with 1 tsp oil to protect your seasoning.
  • ✓Bring skirt steak strips out of the fridge 15 minutes before griddling and pat bone-dry for the crispiest sear.

🧊 Storage, Freezing & Safe Reheating

Refrigerate leftovers in an airtight container at 40°F (4°C) for up to 4 days, or freeze for up to 2 months. Reheat to 165°F (74°C) before serving.

Frequently Asked Questions

What temperature should my Blackstone griddle be for Sizzling Beef Fajitas with Charred Onions and Poblano Peppers?

Aim for 400°F–425°F (medium-high) for searing meats and 350°F (medium) for eggs, tortillas, or delicate sauces.

Avocado oil or refined canola oil works best for initial high-heat searing (smoke point > 450°F), followed by real butter in the final minute for flavor.
