Step-by-Step Instructions
Step 1: Preheat the Oven & Prepare the Baking Sheet
- Preheat your oven to 400°F (200°C).
- Line a large baking sheet with parchment paper or lightly grease it to prevent sticking.
🔥 Why use parchment paper? It makes cleanup easier and prevents food from sticking while roasting.
Step 2: Prepare the Chicken & Vegetables
- In a large bowl, combine:
✔ Sliced chicken breast
✔ Sliced bell peppers (red, yellow, green)
✔ Sliced red onion
✔ Minced garlic
✔ 2 tbsp olive oil - Toss everything until evenly coated.
💡 Want extra flavor? Marinate the chicken for 30 minutes in the seasoning mix before baking!
3 Step: Season the Fajitas
- Sprinkle the following over the chicken and vegetables:
✔ Chili powder
✔ Smoked paprika
✔ Cumin
✔ Oregano
✔ Salt & black pepper
✔ Red pepper flakes (if you like spice!) - Toss again until everything is well-coated with seasoning.
🔥 Pro Tip: Add extra lime juice before serving for a zesty kick!
Now that our chicken and veggies are perfectly seasoned, it’s time to roast everything to juicy, flavorful perfection. With just a few easy steps, you’ll have restaurant-quality fajitas in no time!
Step 4: Roast the Chicken & Vegetables
- Spread the seasoned chicken, bell peppers, and onions evenly across the prepared baking sheet.
- Make sure everything is in a single layer for even roasting.
🔥 Pro Tip: Avoid overcrowding the pan to ensure proper caramelization instead of steaming.
- Place the sheet pan in the preheated oven (400°F/200°C).
- Bake for 20-25 minutes, stirring halfway through to ensure even cooking.
Step 5: Broil for a Charred Finish (Optional)
- If you love that grilled fajita-style char, turn your oven to broil in the last 2-3 minutes of baking.
- Keep a close eye on the fajitas while broiling to prevent burning.
🔥 Why broil? It adds that smoky, restaurant-style crispness to the chicken and veggies!
6 Step: Finish with Lime & Cilantro
- Remove the fajitas from the oven and squeeze fresh lime juice over the mixture.
- Sprinkle with chopped fresh cilantro for a burst of freshness.
💡 Lime juice enhances all the flavors and gives the fajitas a bright, zesty kick!
Step 7: Serve & Enjoy!
- Warm up flour or corn tortillas in a dry skillet or microwave.
- Load each tortilla with chicken, bell peppers, and onions.
- Top with:
✔ Sour cream
✔ Guacamole
✔ Salsa
✔ Shredded cheese
🔥 Want a low-carb option? Skip the tortillas and serve these fajitas over lettuce or cauliflower rice for a keto-friendly meal.
