Instructions

  1. Step 1: Preheat oven to 425°F. In a large bowl, toss 2 medium sliced bell peppers and 2 medium cubed sweet potatoes with 2 tbsp olive oil, 1 tsp salt, 1/2 tsp black pepper, and 1 tsp fresh thyme leaves until evenly coated.
  2. Step 2: Arrange the vegetables in a single layer on a large rimmed baking sheet, leaving space for the chicken.
  3. Step 3: Pat 4 bone-in, skin-on chicken thighs dry with paper towels. In a small bowl, mix 2 tbsp Cajun seasoning and 1 tsp garlic powder. Rub this spice blend evenly over both sides of the chicken thighs.
  4. Step 4: Place the seasoned chicken thighs skin-side up on the baking sheet alongside the vegetables. Drizzle the remaining 1 tbsp olive oil over the chicken.
  5. Step 5: Roast in the preheated oven for 35-40 minutes, until the chicken reaches an internal temperature of 165°F and the vegetables are tender with caramelized edges.
  6. Step 6: Remove from oven and let rest for 5 minutes before serving, allowing the juices to redistribute.

How do I store leftover Sheet Pan Cajun-Spiced Chicken and Roasted Vegetables?

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 bell peppers (red and yellow) from drying out.

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

How do I scale Sheet Pan Cajun-Spiced Chicken and Roasted Vegetables for a different number of people?

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.
