Growing up in the bustling city of Chicago, my childhood was a tapestry of vibrant flavors and heartwarming aromas.

Expert Tips for Success
For the juiciest chicken, make sure not to overcrowd the baking sheet. This ensures even cooking and prevents steaming. If you prefer a bit of char on your fajitas, place them under the broiler for the last 2-3 minutes of cooking. Always let the chicken rest for a few minutes before serving to lock in the juices.
COOKING TOOLS
When I make this recipe, my go-to tool is the MOSFiATA 8″ Professional Chef’s Knife. It makes slicing the chicken and vegetables a breeze. For perfectly cooked chicken, the MEATER SE Smart Meat Thermometer ensures that I never overcook the chicken, keeping it juicy and tender.

Variations and Substitutions
Feel free to customize this recipe by adding your favorite vegetables like zucchini or mushrooms. For a spicier kick, add a pinch of cayenne pepper or some sliced jalapeños. If you’re not on a Whole30 diet, serve these fajitas with warm tortillas or over a bed of rice for a complete meal.
Serving Suggestions
These chicken fajitas pair beautifully with a fresh avocado salad or a side of cauliflower rice. For a refreshing drink, try serving with a glass of sparkling water infused with lime and mint. This meal is perfect for a family dinner or a gathering with friends.

FAQs
Can I make this recipe ahead of time?
Yes, you can prep the ingredients ahead of time and store them in the refrigerator. When ready to cook, simply toss them on a baking sheet and bake as directed.
