Ingredients You’ll Need

For the marinade:

• Flank steak – tender and flavorful, ideal for fajitas
• Fresh lime juice – bright, zesty citrus
• Vegetable or olive oil – carries the marinade and helps it sear
• Garlic, minced – bold aroma
• Ground cumin – warm, earthy Tex-Mex flavor
• Brown sugar (or honey) – a subtle caramelized sweetness
• Black pepper and salt – season and deepen everything

For the fajitas:

• Bell peppers, sliced – sweet, colorful, and slightly crisp
• Sweet onion, sliced – rich and caramelized
• Vegetable oil – helps the veggies char

For serving:

• Pico de gallo, shredded cheddar, guacamole, sour cream, and fresh cilantro

How to Make Copycat Chili’s Steak Fajitas

Step 1: Marinate the steak. In a bowl, whisk together the lime juice, oil, minced garlic, cumin, brown sugar (or honey), salt, and black pepper. Add the flank steak and turn to coat. Cover and refrigerate at least 30 minutes, or up to 4 hours for the best flavor.

Step 2: Preheat the air fryer. Set it to 400°F (200°C) and let it preheat for 3–5 minutes.

Step 3: Cook the steak. Remove the steak from the marinade and place it in the basket. Air fry at 400°F for 10–12 minutes, flipping halfway, until it reaches your desired doneness (130°F for medium-rare, 140°F for medium).

Step 4: Rest the steak. Transfer to a cutting board, tent with foil, and let it rest 5 minutes before slicing. This keeps it juicy.

Step 5: Cook the vegetables. Toss the sliced peppers and onions with oil, salt, and pepper. Air fry at 380°F for 8–10 minutes, shaking the basket halfway, until softened and lightly charred.

Step 6: Assemble and serve. Slice the rested steak thin, against the grain. Serve with warm tortillas, pico de gallo, guacamole, sour cream, shredded cheese, and cilantro.

Tips for the Best Fajitas

• Marinate longer if you can. Thirty minutes works, but up to 4 hours deepens flavor and tenderness.
• Use high heat. 400°F for the steak and 380°F for the veggies gives you that charred exterior while keeping the inside juicy.
• Always slice against the grain. This is the difference between tender and chewy steak.
• Serve immediately. Fajitas are best while everything is still sizzling and hot.

Storing and Reheating

• Store leftovers in an airtight container in the fridge up to 3 days. Keep steak, veggies, and toppings separate for best quality.
• Reheat in the air fryer at 350°F for 4–5 minutes to keep that crisp texture, or warm gently in a skillet.

What to Serve With Steak Fajitas

Round out the meal with classic Mexican sides: warm flour tortillas, Mexican rice or cilantro-lime rice, and a crisp salad with lime vinaigrette. A cold mango daiquiri or iced tea makes the perfect drink to pull it all together.

Frequently Asked Questions

Can I use a different cut of steak? Yes — skirt steak or sirloin both work well. Adjust the cooking time based on thickness.

How do I make it spicier? Add chopped jalapeños to the marinade, sprinkle in chili powder or cayenne, or finish with hot sauce.

Can I make the marinade ahead? Absolutely. It keeps in the fridge up to 24 hours, and the extra time only builds flavor.

Can I cook this on the stovetop instead? Yes. Sear the steak in a hot skillet or on a grill, and sauté the peppers and onions over medium-high heat until charred.

How do I know when the steak is done? Use a meat thermometer: 130°F for medium-rare, 140°F for medium.

Can I swap the vegetables? Sure — zucchini, mushrooms, or corn all work. Slice and cook them alongside the peppers and onions.
