Juicy strips of boneless skinless chicken breasts seared with colorful bell peppers and sweet onion make for a crowd-pleasing meal that comes together with pantry spices and a quick salsa, guacamole, or sour cream on the side. Use warmed tortillas and a squeeze of lime to finish each bite. This is a simple plate that feels special without a fuss.

Why you’ll love this version

The technique here is straightforward: cut the chicken and vegetables into strips, season with a simple spice blend, and cook everything quickly in a hot skillet so the chicken stays tender and the peppers retain a little crunch. There’s minimal clean-up and maximum flavor, and the recipe scales easily if you want to feed more people. It’s also very adaptable—swap the peppers, add a dash of smoked paprika, or top with fresh herbs for a slightly different profile.

Ingredients

• 3-4 Boneless Skinless Chicken Breasts, cut into strips
• 1 White or Yellow Onion, cut into wedges, then sliced into strips
• 3 Bell Peppers, I used a red, orange and yellow, seeds and ribs removed, sliced into strips
• Extra Virgin Olive Oil
• 1 teaspoon Chili Powder
• ½ teaspoon Onion Powder
• ½ teaspoon Cumin
• ½ teaspoon freshly ground Black Pepper
• Kosher Salt, to taste
• Tortillas (warmed), Salsa, Guacamole, Sour Cream, to serve, optional
• Lime, optional, to squeeze over cooked chicken if desired

Prep ahead tips

• Slice the chicken and vegetables up to 2 hours ahead and store covered in the refrigerator so the actual cook time is even faster.
• Measure out the spices into a small bowl or shaker to make seasoning a one-step move at the skillet.
• Warm tortillas quickly by wrapping them in foil and placing them in a low oven for 10 minutes, or microwave stacked tortillas between damp paper towels for 20–30 seconds.

Equipment

• Large skillet or cast-iron pan
• Sharp knife and cutting board
• Tongs or spatula
• Small bowl for spices

Step-by-step instructions

The directions below have been rewritten into clear, step-by-step wording so you can follow along easily while cooking. The order follows the original recipe and keeps the exact ingredient amounts listed above.

1. Prepare your ingredients. Cut 3–4 boneless skinless chicken breasts into even strips. Trim and cut 1 white or yellow onion into wedges, then slice those wedges into thin strips. Core and seed 3 bell peppers (red, orange, yellow recommended) and slice each into strips. Measure out 1 teaspoon chili powder, ½ teaspoon onion powder, ½ teaspoon cumin, and ½ teaspoon freshly ground black pepper.
2. Season the chicken. In a bowl or on a plate, drizzle a small amount of extra virgin olive oil over the chicken strips—about 1–2 tablespoons total to help spices adhere. Sprinkle the chili powder, onion powder, cumin, black pepper, and kosher salt (to taste) evenly over the chicken. Toss to coat every strip in the spice blend.
3. Heat the skillet. Place a large skillet or cast-iron pan over medium-high heat and add 1–2 tablespoons extra virgin olive oil. Let the oil heat until it shimmers but does not smoke; this high heat is key to getting a quick sear on the chicken and vegetables.
4. Cook the chicken strips. Arrange the seasoned chicken strips in a single layer in the hot skillet. Avoid overcrowding the pan so the chicken browns instead of steaming; if necessary, cook in two batches. Let the chicken cook undisturbed for about 3–4 minutes to develop color, then flip or toss and cook another 3–4 minutes, until the chicken is cooked through and no longer pink in the center. Internal temperature should reach 165°F (75°C) if you check with a thermometer.
5. Remove the chicken and rest. Transfer the cooked chicken strips to a plate and loosely tent with foil while you cook the vegetables. This short rest keeps the chicken juicy.
6. Sauté the onions and peppers. Return the same skillet to medium-high heat and add a touch more olive oil if the pan is dry. Add the sliced onion and bell pepper strips in a single layer. Let them cook without moving for 1–2 minutes to get a little char, then toss or stir and continue cooking for 4–6 minutes total, until the peppers are tender-crisp and the onions are soft and translucent. Season with a pinch of kosher salt and a light grind of black pepper while they cook.
7. Combine chicken and vegetables. Reduce the heat to medium and add the cooked chicken back into the skillet with the onions and peppers. Toss everything together for 1–2 minutes so the flavors meld and the chicken heats through. Taste and adjust seasoning with more kosher salt or black pepper if needed.
8. Serve immediately. Warm tortillas and stack the chicken and vegetable mixture on each one. Offer salsa, guacamole, and sour cream for toppings, and slice lime wedges to squeeze over the assembled fajitas if desired. Serve hot and enjoy.

Serving suggestions

These Easy Chicken Fajitas Recipe are designed to be customizable. Serve with warmed flour or corn tortillas and a selection of toppings so everyone can build their perfect bite. I like to lay out bowls of salsa, sliced avocado or guacamole, a dollop of sour cream, chopped cilantro, and lime wedges. Add a simple side salad, some cilantro-lime rice, or black beans for a fuller meal.

Flavor variations and swaps

• Spice it up: Add ¼ teaspoon smoked paprika or a pinch of cayenne to the spice mix for a smoky heat.
• Herb finish: Sprinkle chopped fresh cilantro over the finished fajitas for a bright finish.
• Veggie-forward: Add sliced mushrooms or zucchini to the pepper and onion mix for extra veggies.
• Cheesy: Top each fajita with shredded cheese while everything is still hot so it melts slightly.

Make-ahead and storage

You can prepare the chicken and vegetables ahead of time. Store cooked chicken and peppers in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet over medium heat until warmed through, or microwave in short bursts. Tortillas can be warmed just before serving to keep them pliable.

Nutritional notes

Boneless skinless chicken breasts provide a lean source of protein, while the trio of bell peppers adds vitamin C and color. Using extra virgin olive oil keeps the recipe pantry-friendly and heart-healthy. For a lighter serving, skip the sour cream or choose a low-fat Greek yogurt alternative as a topping.

Common troubleshooting

• If your chicken is dry: Make sure you’re not overcooking it; check for an internal temperature of 165°F (75°C) and pull from heat as soon as it’s done. Slicing the breasts into strips shortens cook time and helps keep them juicy.
• If peppers are too soft: Cook them quickly over higher heat so they stay tender-crisp—this brings out a better texture.
• If the pan is crowded: Cook in batches. Overcrowding causes steaming instead of browning.
