Instructions

1. Preheat the Oven:

  • Set your oven to 425°F (218°C).

2. Prepare the Ingredients:

3. Mix the Seasoning:

  • In a small bowl, combine all the fajita seasoning ingredients.

4. Assemble on a Sheet Pan:

  • Drizzle with olive oil and lime juice.
  • Sprinkle the fajita seasoning over the top.
  • Toss everything together until evenly coated.
  • Spread in a single layer to ensure even cooking.

5. Bake:

  • Roast in the oven for 20-25 minutes, stirring halfway through.

Notes

  • Meal Prep: Slice and season the chicken and veggies ahead of time; store in the fridge for up to 24 hours before cooking.
  • Prevent Soggy Veggies: Ensure the oven is fully preheated and do not overcrowd the pan. Use two sheet pans if necessary.
  • Storage: Keep leftovers in an airtight container in the fridge for up to 4 days.
  • Reheating: Reheat in a skillet over medium heat for the best texture. Avoid microwaving, as it can make the chicken rubbery.
