Ingredients

  • Boneless skinless chicken thighs: Provide juicy flavorful protein and hold up well to roasting Look for fresh chicken with a slight pink hue and no odor
  • Bell peppers: Bring natural sweetness and beautiful color Choose glossy firm peppers for best results
  • Red onion: Adds mild bite and caramelizes beautifully Pick heavy onions with crisp skin
  • Olive oil: Helps vegetables roast evenly and keeps chicken moist Select extra virgin for richer depth
  • Cajun seasoning: Packs a punch of smoky spicy flavor Use a blend with quality paprika and dried herbs and adjust for salt and heat to taste

Instructions

Preheat the Oven
Set your oven to four hundred twenty five degrees Fahrenheit Two hundred twenty degrees Celsius to get a nice quick roast and crispy edges
Mix the Ingredients
In a large mixing bowl add the chicken thighs sliced bell peppers and red onion Drizzle the olive oil and toss in the Cajun seasoning Use your hands to combine everything thoroughly so each piece is well coated with oil and spice
Arrange on the Sheet Pan
Spread the chicken and vegetables in a single layer on a large baking sheet Make sure the pieces are not overlapping to ensure even roasting and caramelization
Roast to Perfection
Place in the oven and roast for about twenty five minutes The chicken is done when it reaches an internal temperature of one hundred sixty five degrees Fahrenheit seventy four degrees Celsius and the vegetables are tender with crisped edges
Rest and Serve

The bold Cajun seasoning is what takes simple chicken and vegetables to another level I have memories of my dad sneaking a taste of the roasted onions straight from the pan because they get so sweet smoky and caramelized

Storage Tips

Leftovers keep well in the fridge for up to four days Store in an airtight container to maintain tenderness and flavor Warm gently in the oven or microwave If you want fresh crisp veggies avoid freezing as the texture can change

Ingredient Substitutions

Chicken breast will work in place of thighs just check for doneness a bit earlier You can swap in broccoli florets or zucchini for the bell peppers and red onion too If Cajun seasoning is too fiery try smoked paprika and a pinch of dried thyme for a milder spin

Serving Suggestions

This sheet pan wonder loves fluffy rice quinoa or even creamy mashed potatoes Fresh lemon squeezed just before serving offers a nice bright contrast For extra crunch add a quick cabbage slaw on the side and call it dinner
