Ingredients and Preparation

One of the things that makes this recipe approachable for beginners is the simplicity of the ingredients. They’re easy to find at any grocery store and come together to create a flavorful and vibrant meal.

Here’s what you’ll need:

• 300g (11 oz) Chicken breast – Cut into chunks for even cooking.
• 1 tablespoon Chili powder – Adds a mild heat and rich flavor.
• 1 tablespoon Smoked paprika – Gives a subtle smokiness to the dish.
• 1 teaspoon Garlic powder – A quick way to add garlicky goodness.
• 1 teaspoon Onion powder – Enhances the overall savory profile.
• 1 teaspoon Cumin – Brings warm, earthy tones typical of Mexican dishes.
• 1 teaspoon Ground coriander – Adds a citrusy undertone.
• 1 pinch Sea salt – Balances and enhances all the other flavors.
• 1 pinch Ground black pepper – A touch of sharpness.
• 1 pinch Sugar – Helps balance the spices and caramelize the veggies.
• 1 tablespoon Olive oil – Coats the chicken and veggies to help them roast beautifully.
• 3 Bell peppers – Thinly sliced; choose a mix of red, yellow, and green for vibrant colors.
• 1 Red onion – Thinly sliced for sweetness and texture.
• 4 Tortilla wraps – Soft and ready to hold all the delicious fillings.

Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 200°C/180°C fan/400°F/Gas 6. Starting with a hot oven ensures that the chicken and veggies cook evenly and develop those flavorful caramelized edges.

Step 2: Prepare the Fajita Seasoning

In a small bowl, combine the chili powder, smoked paprika, garlic powder, onion powder, cumin, ground coriander, salt, pepper, and sugar. Mix well to create your homemade fajita seasoning. This blend is far superior to store-bought mixes and can be adjusted to suit your taste.

Step 3: Marinate the Chicken and Vegetables

In a large bowl, add the chicken chunks, bell peppers, red onion, and olive oil. Sprinkle the fajita seasoning over the mixture and toss everything until well coated. Using your hands ensures the spices are evenly distributed. For the best flavor, cover the bowl and refrigerate for at least two hours, or even overnight.

Beginner Tip: If you’re short on time, even 15-20 minutes of marinating will still yield great results.

Step 4: Assemble in an Oven-Proof Dish

Transfer the marinated chicken and vegetables into a large, shallow oven-proof dish. Spread everything out evenly to avoid overcrowding, which can cause the ingredients to steam rather than roast.

Step 5: Bake

Place the dish in the preheated oven and bake for 25-30 minutes, or until the chicken is fully cooked and the vegetables are tender. You’ll know the chicken is done when it reaches an internal temperature of 75°C (165°F) and is no longer pink in the center.

Beginner Tip: If you don’t have a meat thermometer, cut into the thickest piece of chicken to check for doneness.

Step 6: Add Finishing Touches

Once the fajitas are cooked, remove the dish from the oven and squeeze the juice of 1 lime over the top. Sprinkle with fresh coriander (cilantro) for a burst of color and flavor.

Step 7: Assemble and Serve

Divide the chicken and veggie mixture among the tortilla wraps. Serve with your choice of salsa, guacamole, sour cream, and tortilla chips on the side. For an alternative serving option, spoon the mixture over cooked rice or quinoa for a hearty fajita bowl.

Beginner Tips and Notes

• Marinating Matters: While it’s tempting to skip the marinating step, it’s worth the extra time. Marinating allows the chicken to absorb all the spices, resulting in a more flavorful dish.
• Avoid Overcrowding: When arranging the chicken and veggies in the baking dish, give them enough space to roast properly. Overcrowding traps steam, which prevents the ingredients from browning and caramelizing.
• Customizing the Heat: If you’re sensitive to spice, reduce the chili powder in the seasoning. For extra heat, add a pinch of cayenne pepper or some sliced jalapeños to the mix.
• Prep in Advance: Slice the veggies and mix the seasoning ahead of time to make assembly quicker on busy nights.
• Troubleshooting Overcooking: If the chicken starts to brown too quickly, loosely cover the dish with aluminum foil for the remaining baking time.

Serving Suggestions

While these fajitas are fantastic on their own, pairing them with the right sides can take your meal to the next level.

• Rice or Quinoa: Serve the fajitas over a bed of cooked rice or quinoa for a hearty and filling meal.
• Homemade Salsa: A quick mix of diced tomatoes, onions, jalapeños, lime juice, and fresh cilantro pairs beautifully with the fajitas.
• Creamy Guacamole: Mash ripe avocados with lime juice, salt, and diced tomatoes for a creamy, tangy addition.
• Tortilla Chips: Crunchy tortilla chips are great for scooping up any leftover fajita filling.

For leftovers, store the chicken and veggie mixture in an airtight container in the fridge for up to three days. Reheat in the microwave or on the stovetop for a quick lunch or dinner.
