Step-by-Step Instructions

Step 1: Marinate the Steak

Combine all marinade ingredients. Add steak, coat well, and marinate at least 30 minutes at room temperature or up to 8 hours in the fridge. The longer the better — but even 30 minutes makes a huge difference.

Step 2: Cook the Peppers and Onions

Heat a cast iron skillet over high heat until smoking. Add olive oil, then peppers and onions. Cook without stirring for 2 minutes to get charred edges. Toss and cook 3 more minutes until softened and slightly caramelized. Season with salt. Remove and set aside.

Step 3: Sear the Steak

Remove steak from marinade and pat slightly dry. In the same screaming-hot skillet, sear steak 3 to 4 minutes per side for medium-rare. Do not move it while searing — let it develop a crust. Rest 5 minutes, then slice thinly against the grain.

Step 4: Serve

Return peppers and onions to the pan with the steak juices. Serve sizzling directly from the skillet with warm tortillas and all your favorite toppings. A squeeze of fresh lime over everything is non-negotiable.

Tips for the Best Fajitas

• Always slice against the grain — this is the single most important tip for tender steak
• Use a cast iron pan — nothing else gets hot enough for proper searing

Storing Tips

• Store steak and peppers separately in the fridge up to 3 days
• Reheat in a hot skillet for 2 minutes — do not microwave the steak
• Great for meal prep — make a big batch and use in bowls, wraps, or salads all week

FAQs

1. What is the best cut of steak for fajitas?
Flank steak or skirt steak are the traditional choices. Both are flavorful, affordable, and slice beautifully against the grain.

2. Can I make chicken fajitas with this recipe?
Absolutely — use the same marinade with boneless chicken thighs or breasts. Reduce cook time to 6 to 7 minutes per side.

3. How do I know when steak is done?
Use a meat thermometer: 130 F for medium-rare, 140 F for medium. Flank steak is best at medium-rare.
