Pro Tips

  • Slice everything thin and evenly so it cooks at the same rate.
  • Don’t overcrowd the pan—spread everything out for max caramelization.
  • Let the sheet pan sit under the broiler for 2-3 minutes at the end for extra char.
  • Use parchment paper for easier clean-up.
  • Warm tortillas in a damp towel in the microwave for 30 seconds to make them soft and flexible.

Tools You’ll Need

  • Large sheet pan
  • Mixing bowl
  • Tongs
  • Measuring spoons
  • Cutting board and sharp knife

Substitutions & Variations

  • Chicken thighs instead of breasts = juicier
  • Use fajita seasoning mix if you’re short on spices
  • Add zucchini or mushrooms for more veggies
  • Swap chicken for shrimp or beef strips
  • Try corn tortillas if you’re gluten-free

Make-Ahead Tips

  • Slice veggies and chicken the night before—store them separately in airtight containers.
  • Mix spices into a little jar ahead of time.
  • You can even marinate the chicken and store it for up to 24 hours in the fridge.

Step 2: Mix chicken and veggies with oil and spices.

Step 4: Bake for 20–25 minutes.

Bake until chicken is cooked through and veggies are slightly charred at the edges.

Step 5: Squeeze lime juice on top.

As soon as it comes out of the oven, squeeze fresh lime juice over the fajitas.

Leftovers & Storage

  • Store leftover chicken and veggies in an airtight container for up to 3 days.
  • Reheat in a skillet for best texture or microwave for convenience.
  • Great for tacos, quesadillas, or over rice the next day!

Why This Recipe Works (Quick Science)

The high oven heat quickly cooks the thin slices of chicken and veggies, helping them caramelize without drying out. The oil and spices coat everything so the flavors really stick. Cooking everything together means the juices mix, making each bite flavorful and juicy.

  • Day 2: Fajita rice bowls with black beans and avocado
  • Day 3: Quesadillas using leftover filling and cheese

Common Mistakes

  • Cutting the chicken or veggies too thick—then they take forever to cook
  • Overcrowding the pan—everything steams instead of roasts
  • Not preheating the oven—then you miss that nice char
  • Skipping the lime at the end—it really brightens everything up

What to Serve With

  • Mexican rice or cilantro lime rice
  • Black beans or refried beans
  • Chips and guacamole
  • Fresh corn salad
  • A cold limeade or horchata
