Servings 4 servings

Ingredients

  

• 1.5 pounds boneless, skinless chicken thighs (or breasts, pounded to even thickness)
• 2 cups broccoli florets
• 1 red bell pepper, sliced
• 1 yellow bell pepper, sliced
• 1 red onion, cut into wedges
• 1 medium zucchini, sliced into half-moons
• 2 tablespoons olive oil (plus more as needed)
• 1 tablespoon fresh lemon juice (optional, for finishing)
• 2 teaspoons smoked paprika
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 1 teaspoon dried oregano
• 1 teaspoon dried thyme
• 1 teaspoon kosher salt (reduce to 1/2 teaspoon if salt-sensitive)
• 1/2 teaspoon black pepper
• 1/2 to 1 teaspoon cayenne pepper (adjust to taste)
• Lemon wedges for serving
• Fresh parsley or green onions, chopped
• Cooked rice, quinoa, or warm tortillas on the side

Instructions

 

• Preheat the oven: Set to 425°F (220°C). Line a large sheet pan with parchment or lightly oil it to prevent sticking.
• Mix the Cajun spice: In a small bowl, combine smoked paprika, garlic powder, onion powder, oregano, thyme, salt, black pepper, and cayenne. Stir until evenly blended.
• Prep the chicken: Pat chicken dry with paper towels. Toss with 1 tablespoon olive oil and about half of the Cajun spice mix. Make sure every piece is coated. Set aside to let the seasoning soak in while you prep the vegetables.
• Prep the veggies: Add broccoli, bell peppers, red onion, and zucchini to a large bowl. Drizzle with 1 tablespoon olive oil and sprinkle with the remaining Cajun spice. Toss well so every piece gets a good hit of seasoning.
• Arrange on the sheet pan: Spread the vegetables out in a single layer, leaving space for the chicken. Place the chicken pieces on the pan without overlapping. Crowded pans steam, so use two pans if needed.
• Roast: Bake for 20–25 minutes, flipping the chicken once halfway through. Veggies should be tender with caramelized edges, and chicken should reach an internal temperature of 165°F (74°C).
• Optional broil: For extra char, switch to broil for 1–2 minutes at the end. Watch closely to avoid burning.
• Finish and serve: Squeeze fresh lemon juice over everything and sprinkle with chopped parsley or green onions. Serve as is, or pair with rice, quinoa, or tortillas.

What Makes This Special

Save

This recipe is a great example of how simple ingredients can deliver huge flavor. A homemade Cajun spice mix creates a smoky, peppery crust on the chicken, while the veggies roast into sweet, crispy bites.

It’s a full meal on one pan, which means fewer dishes and less time in the kitchen. You can scale it up for meal prep, customize the heat level, and swap in whatever vegetables you have on hand.

• One-pan convenience: Minimal cleanup and streamlined cooking.
• Balanced plate: Protein-rich chicken, fiber-packed veggies, and healthy fats.
• Highly customizable: Works with thighs or breasts and nearly any roast-friendly vegetable.
• Meal-prep friendly: Reheats well and tastes even better the next day.

Storage Instructions

• Refrigerate: Cool completely, then store in an airtight container for up to 4 days.
• Freeze: The chicken freezes well for up to 2 months. Veggies can be frozen but may soften upon reheating.
• Reheat: For best texture, reheat on a sheet pan at 375°F (190°C) for 8–10 minutes.

  Microwave in short bursts if you’re in a hurry.

• Meal prep tip: Store chicken and veggies separately to keep the veggies from getting soggy.

Health Benefits

• Lean protein: Chicken supports muscle health and keeps you fuller longer.
• Vegetable variety: Broccoli, peppers, onion, and zucchini provide fiber, vitamins A, C, and K, and antioxidants.
• Smart fats: Olive oil adds heart-healthy monounsaturated fats.
• Lower sodium control: Making your own spice blend helps you manage salt and avoid additives.
• No heavy creams or sauces: You get bold flavor without a heavy calorie load.

What Not to Do

• Don’t overcrowd the pan: If ingredients touch too much, they’ll steam instead of roast. Use two pans if needed.
• Don’t skip drying the chicken: Moisture prevents browning and crust formation.
• Don’t overdo the cayenne: Start modestly and adjust later with hot sauce if you want more heat.
• Don’t cut uneven pieces: Keep chicken and veggies in similar sizes for even cooking.
• Don’t forget to flip: Turning the chicken halfway through helps even browning.

Variations You Can Try

• Protein swap: Use turkey tenderloins, shrimp (roast shrimp for 8–10 minutes only), or tofu (press first, then season generously).
• Veggie swap: Try sweet potatoes, cauliflower, Brussels sprouts, or green beans. Adjust roasting time for denser veggies (add 5–10 minutes).
• Creamy drizzle: Mix Greek yogurt with lemon and a pinch of Cajun spice for a cooling sauce.
• Extra smoky: Add a touch of chipotle powder or replace smoked paprika with a hotter variety.
• Low-carb bowl: Serve over cauliflower rice with extra greens.
• Sandwich style: Slice the chicken and pile into a toasted baguette with roasted peppers and a smear of mayo or yogurt sauce.
