Preparing the Ingredients
Start by gathering your fresh ingredients. You’ll need chicken breasts, bell peppers, onions, fajita seasoning, olive oil, and your favorite tortillas. Slice the chicken into strips and chop the peppers and onions into thin slices.
For added flavor, toss the chicken and vegetables with a bit of olive oil and sprinkle with fajita seasoning. This step ensures every bite is bursting with summer flavor and cooks evenly in the air fryer.
Cooking the Chicken and Vegetables
Preheat your Ninja DoubleStack XL Air Fryer using the air fry function at 400°F. Place the chicken strips in one basket and the vegetables in the other. Set the independent controls to cook for about 12-15 minutes, shaking the baskets halfway through. The smart doneness feature helps prevent overcooking.
While the chicken and veggies cook, prepare your tortillas and toppings like sour cream, salsa, and shredded cheese. The dual baskets allow you to multitask efficiently, keeping everything hot and fresh.
Assembling the Fajitas
Once cooked, transfer the chicken and vegetables to a serving dish. Warm the tortillas in the oven or microwave, then fill each with the crispy chicken and sautéed peppers and onions. Top with your preferred garnishes for a fresh, summer-inspired meal.
This method ensures perfectly cooked components with minimal fuss, so you can enjoy your meal outdoors or indoors without heating up your entire kitchen.
Tips for Perfect Fajitas
- Use the smart thermometer to check that chicken reaches an internal temperature of 165°F for safety and juiciness.
- Partially open the baskets during cooking for extra crispiness if desired.
- Experiment with different seasonings or add a squeeze of lime before serving for an extra summer zing.
