Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F. In a large bowl, toss 1.5 lbs boneless skinless chicken thighs with 3 tbsp olive oil and 2 tbsp Cajun seasoning until fully coated.
  2. Step 2: Add 1 large sliced red bell pepper, 1 large sliced yellow bell pepper, 1 large sliced green bell pepper, 1 medium red onion cut into wedges, and 3 cloves minced garlic to the bowl. Toss to combine evenly.
  3. Step 3: Spread the chicken and vegetables in a single layer on a large rimmed baking sheet.
  4. Step 4: Roast in the preheated oven for 25-30 minutes, flipping the chicken and stirring vegetables halfway through, until chicken reaches an internal temperature of 165°F and peppers are tender and slightly charred.

  6. Step 6: Serve immediately with lemon wedges to squeeze over the top for a bright finish.

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep olive oil from drying out.

Can I substitute ingredients in Sheet Pan Cajun-Spiced Chicken and Peppers?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
