How to Make Plancha Steak Fajitas
Step 1: Marinate the Steak
In a bowl or zip-top bag, mix olive oil, lime juice, soy sauce, garlic, and all the spices. Add steak and turn to coat well. Marinate in the fridge for at least 1 hour, up to overnight.
Step 2: Cook the Vegetables
Heat a tablespoon of olive oil on your plancha or cast iron skillet over high heat. Add bell peppers and onion, season with salt and pepper, and sauté for 5–6 minutes until slightly charred and tender. Transfer to a plate and keep warm.
Step 3: Cook the Steak
Remove steak from marinade and pat dry slightly. Add to the hot plancha and cook for 4–5 minutes per side, depending on thickness, until medium-rare. Let rest for 5 minutes.
Step 4: Slice the Steak
Transfer steak to a cutting board and slice thinly against the grain.
Step 5: Assemble and Serve
Serve steak with sautéed peppers and onions, warm tortillas, and your favorite toppings like guacamole, salsa, and lime wedges.
Leftovers & Storage
- Store leftover steak and veggies separately in airtight containers in the fridge for up to 4 days.
- Reheat in a hot skillet or microwave until warmed through.
- Leftovers make great quesadillas, rice bowls, or fajita salads.
- Avoid freezing cooked peppers as they can become mushy.
Recipe FAQ
Can I use a different cut of beef for fajitas?
Yes, flank and skirt steak are ideal because they cook quickly and stay tender when sliced against the grain. But you can also use sirloin or flat iron steak—just adjust the cook time slightly and be sure to slice thinly.
Do I have to use a plancha?
Not at all. A cast iron skillet or grill pan works just as well. The key is high heat to create that seared, smoky flavor. If you’re grilling outdoors, a flat griddle over the grill works too.
How long should I marinate the steak?
At least 1 hour, but overnight is best for deep flavor. If you’re short on time, even 30 minutes can help tenderize and season the meat.
What tortillas work best for fajitas?
Both corn and flour tortillas are great—it’s just personal preference. Warm them before serving so they stay soft and pliable.
Can I make this recipe ahead for meal prep?
Yes. Marinate the steak and prep the veggies in advance. After cooking, store everything in separate containers. It keeps well for up to 4 days and reheats beautifully for lunches or dinners.
