What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples or easy to grab at the store, making it a no-brainer for quick meals.

• Chicken: 1 ½ pounds (700g) boneless, skinless chicken breasts or thighs, thinly sliced (thighs add juiciness, breasts keep it lean)
• Bell Peppers: 3 medium-sized (red, yellow, and green for a colorful mix), sliced into strips
• Onion: 1 large yellow or white onion, thinly sliced
• Garlic: 3 cloves, minced (fresh garlic packs the best punch)
• Olive Oil: 2 tablespoons (I use extra virgin for richer flavor)
• Fajita Seasoning:
  • 1 teaspoon chili powder
  • 1 teaspoon smoked paprika (adds that lovely smoky warmth)
  • 1 teaspoon ground cumin
  • ½ teaspoon onion powder
  • ½ teaspoon garlic powder
  • ½ teaspoon dried oregano
  • Salt and freshly ground black pepper, to taste
• Fresh Lime Juice: From 1 lime (brightens the whole dish)
• Optional Toppings:
  • Chopped fresh cilantro
  • Sour cream or Greek yogurt
  • Shredded cheese
  • Warm flour or corn tortillas

If you want to swap things up, you can use chicken tenders instead of breasts or thighs. For a dairy-free version, leave off the cheese and sour cream or use vegan alternatives. And if you can’t find smoked paprika, regular paprika works, but that smoky note really lifts the dish.

Equipment Needed

• Large Skillet or Frying Pan: A 12-inch (30 cm) non-stick or cast-iron skillet works best to get a nice sear and even cooking.
• Sharp Chef’s Knife: For slicing chicken and veggies thinly and evenly.
• Cutting Board: Preferably separate boards for meat and veggies to keep things safe.
• Spatula or Wooden Spoon: To stir and toss the ingredients in the skillet without scratching the pan.
• Measuring Spoons: For precise seasoning.

If you don’t have a cast iron skillet, a heavy-bottomed stainless steel pan will do just fine. I started cooking fajitas in a budget-friendly non-stick pan and honestly, it worked great for years. Just be sure to avoid overcrowding the pan—that’s the secret to getting those lovely caramelized edges!

Preparation Method

1. Prep Your Ingredients (10 minutes): Thinly slice the chicken into even strips about ½ inch (1.25 cm) thick. Slice your bell peppers and onions into similar thin strips. Mince the garlic finely. Pre-measuring your fajita seasoning mixture helps keep things moving quickly.
2. Heat the Skillet (2 minutes): Place your skillet over medium-high heat and add 2 tablespoons of olive oil. Let it heat until shimmering but not smoking. A hot pan is key for that delicious sear.
3. Cook the Chicken (5-7 minutes): Add the sliced chicken strips in a single layer. Avoid crowding; cook in batches if needed. Let the chicken cook undisturbed for about 2-3 minutes to get a nice brown crust, then stir and cook until no longer pink inside. Season with salt and pepper during this step. Remove the chicken from the skillet and set aside.
4. Sauté the Veggies (5-6 minutes): In the same skillet, add a bit more olive oil if needed. Toss in the sliced onions and bell peppers. Stir occasionally, letting them soften and caramelize slightly. After about 3 minutes, add the minced garlic and cook for another 1-2 minutes until fragrant.
5. Combine and Season (3 minutes): Return the cooked chicken to the skillet with the veggies. Sprinkle the fajita seasoning evenly over everything. Stir well to coat all pieces. Let it cook together for another 2-3 minutes so the flavors meld. Taste and adjust seasoning if needed.
6. Finish with Fresh Lime (1 minute): Squeeze fresh lime juice all over the skillet contents and give it a final stir. The bright citrus flavor really lifts the dish and balances the smoky spices.
7. Serve Hot: Transfer the chicken fajitas to warm tortillas and pile on your favorite toppings like cilantro, sour cream, or shredded cheese.

Pro tip: Resist the urge to stir constantly when cooking the chicken; letting it sit undisturbed helps develop that crave-worthy brown crust. Also, thin slices are your friend here—they cook quickly and evenly, perfect for that tender bite.

Cooking Tips & Techniques

When it comes to making one-skillet chicken fajitas, a few little tricks can make a big difference. First, always make sure your skillet is hot enough before adding the chicken. I learned the hard way that a lukewarm pan leads to soggy, steamed chicken instead of that delicious sear you want.

Another tip: slice your veggies uniformly. This ensures everything cooks evenly and you don’t end up with crunchy onions but mushy peppers (been there, done that!). Also, don’t overcrowd the pan. If you toss too much in at once, the ingredients steam rather than sauté, losing that signature fajita char.

For spice lovers, consider adding a pinch of cayenne or chipotle powder to the seasoning mix for an extra kick. On the flip side, if cooking for kids, dial back the chili powder to keep things mild but flavorful.

Timing is everything. Start prepping ingredients before you heat the pan—once you start cooking, this dish moves fast. Multitasking with a good mise en place (everything ready and waiting) saves stress and keeps the process smooth.

Finally, don’t skip the fresh lime at the end. It brightens the whole dish and balances the savory spices. One of those simple finishers that makes the recipe feel restaurant-worthy.

Variations & Adaptations

One-skillet chicken fajitas are surprisingly adaptable, letting you tailor the dish to your tastes or dietary needs. Here are a few fun variations I’ve tried and loved:

• Low-Carb Version: Skip the tortillas and serve the fajita mix over cauliflower rice or alongside a fresh green salad for a light, keto-friendly meal.
• Vegetarian Option: Swap chicken for firm tofu or portobello mushrooms, sliced and cooked the same way. The seasoning still shines with these swaps.
• Spicy Southwest Twist: Add a diced jalapeño or chipotle chili in adobo to the skillet for smoky heat. Serve with avocado slices and a dollop of sour cream.
• Different Proteins: Try shrimp or thinly sliced steak for variety. Just adjust cooking times since shrimp cooks super fast and steak benefits from a quick sear.

When I made the vegetarian version with mushrooms for a friends’ night, everyone was surprised by how satisfying and flavorful it was—even the meat eaters were impressed! Feel free to experiment with your favorite veggies or spice blends to make the recipe truly yours.

Serving & Storage Suggestions

These chicken fajitas are best served piping hot, straight from the skillet, wrapped in warm tortillas. I like to serve them with a side of Mexican rice, black beans, or a simple green salad to round out the meal. A cold cerveza or a fresh lime margarita pairs beautifully if you’re entertaining.

Leftovers? No problem. Store any extras in an airtight container in the refrigerator for up to 3 days. When reheating, warm gently in a skillet over medium heat to keep the chicken tender and veggies crisp. Avoid microwaving, which can make the chicken dry.

Flavors actually deepen after sitting overnight, so sometimes I prep the fajita mix a day ahead for quick dinners during the week. Just reheat and warm your tortillas fresh.
