Ingredients & Substitutions
The printable recipe card below has the full ingredients list and instructions.
- Chicken Breast – substitute with chicken thighs for a juicier option.
- Bell Peppers – add colour and sweetness. Use any combination of red, yellow, green, or orange peppers.
- Red Onion – provides a slightly sweet, savoury flavour. Yellow or white onions work as substitutes if needed.
- Olive Oil – to coat everything in before cooking. You can also use avocado oil.
- Homemade Fajita Seasoning – includes chilli powder, cumin, coriander, garlic powder, salt and pepper. For a no-spice variation, remove the chilli powder.
- Tortillas – I like to use low-carb soft-shell tortillas.
How To Make Sheet Pan Chicken Fajitas
Step 1: Preheat the oven to 180°C (350°F).
Step 2: In a small bowl, combine chilli powder, cumin, coriander, garlic powder, paprika, salt, and pepper.
Step 3: Place the sliced chicken, bell peppers, and red onion on the sheet pan.
Step 4: Drizzle with olive oil and sprinkle the seasoning mixture evenly over the top. Toss everything together with your hands or tongs to coat well.
Step 5: Arrange the chicken and vegetables in a single layer to ensure even cooking.
Step 6: Roast in the preheated oven for 20–25 minutes, or until the chicken is fully cooked.
Step 7: Remove from the oven and serve immediately with warm tortillas, your favourite toppings like guacamole, sour cream, or shredded cheese, and a squeeze of fresh lime juice.
