Let’s Make it together
Preheat Your Oven: Start by preheating your oven to 400°F (200°C). This ensures everything cooks evenly while you prepare the ingredients.
Prepare Your Chicken and Veggies: Cut the boneless chicken into strips and chop the bell peppers and onion into bite-sized pieces. The colors should be vibrant and inviting.
Toss with Olive Oil and Seasoning: In a large bowl, combine the chicken strips with sliced veggies. Drizzle with olive oil and sprinkle generously with fajita seasoning; toss well until everything is coated.
Arrange on a Sheet Pan: Spread the seasoned mixture evenly on a baking sheet lined with parchment paper. This helps with cleanup later and allows even cooking.
Bake Until Juicy and Tender: Place in the preheated oven and bake for about 20-25 minutes. You’ll know it’s done when the chicken is cooked through and slightly caramelized.
Warm Your Tortillas!: While the fajitas are baking, warm your tortillas in a skillet or microwave. This step makes them pliable and ready for wrapping those amazing fillings!
Now that you’ve mastered these steps of making sheet pan chicken fajitas, gather everyone around the table and enjoy! The aroma alone will have them lining up for seconds before you even serve them!
