Ingredients for Easy One‑Pan Chicken and Broccoli with Peppers & Tomato
Here’s everything you need for this easy sheet pan meal:
Chicken & Main Ingredients
- 4 boneless, skinless chicken breasts
- 1 large head of broccoli, cut into florets
- 1 red bell pepper, sliced
- 1 yellow bell pepper, sliced
- 1 cup cherry tomatoes, halved
- 2 tablespoons olive oil
- 2 tablespoons Dijon mustard
- 1 teaspoon salt
- ½ teaspoon black pepper
- 1 tablespoon lemon juice (optional, for finishing)
Ingredient Notes
- Chicken swap: Chicken thighs or turkey breast can be used for juicier meat.
- Vegetable variations: Add zucchini, mushrooms, or asparagus if desired.
- Spice option: Sprinkle paprika, garlic powder, or Italian herbs for extra flavor.
- Healthy tweaks: Use less olive oil for a lighter version, or finish with fresh lemon juice instead of extra fat.
Step-by-Step Instructions
Step 1 – Prepare the Pan and Chicken
Preheat your oven to 400°F (200°C). Line a large sheet pan with parchment paper or lightly grease with olive oil. Place the chicken breasts on the pan and season with salt and pepper. Brush each breast generously with Dijon mustard.
Step 2 – Prepare Vegetables
In a large bowl, toss broccoli florets, bell pepper slices, and cherry tomatoes with olive oil, salt, and pepper. Spread the vegetables evenly around the chicken on the sheet pan. Ensure everything is in a single layer for even roasting.
Step 3 – Roast Everything
Place the sheet pan in the preheated oven and roast for 25–30 minutes, flipping the vegetables halfway through. Chicken is done when the internal temperature reaches 165°F (74°C), broccoli is tender but still vibrant, and bell peppers are slightly caramelized. Cherry tomatoes will burst and release their natural juices.
Step 4 – Finish and Serve
Remove the pan from the oven and drizzle with fresh lemon juice if desired. Serve directly from the pan for a rustic presentation, or plate individually with the vegetables surrounding the chicken.
Pro Tips for Success
- Even Cooking: Cut broccoli and bell peppers into similar sizes for uniform roasting.
- Juicy Chicken: Let chicken rest 5 minutes after roasting before slicing to retain juices.
- Prevent Soggy Veggies: Don’t overcrowd the pan; vegetables should have space to roast.
- Flavor Boost: Sprinkle chopped fresh herbs like parsley or thyme just before serving.
- Optional Cheese: Add grated Parmesan for a cheesy finish without overpowering flavors.
- Meal Prep Friendly: Roast extra chicken and veggies to use in salads or wraps during the week.
Flavor Variations
- Mediterranean Twist: Add olives, sun-dried tomatoes, and oregano for a Greek-inspired dish.
- Spicy Kick: Sprinkle crushed red pepper flakes or drizzle sriracha over the finished dish.
- Garlic Lovers: Roast 4–5 whole garlic cloves with the vegetables for sweet, mellow garlic flavor.
- Asian-Inspired: Swap Dijon for soy sauce and sesame oil, and top with sesame seeds before serving.
- Cheesy Roasted Veggies: Toss broccoli and peppers with a little shredded mozzarella before baking.
Serving Suggestions
- Serve over cooked quinoa or brown rice for a filling, whole-grain meal.
- Pair with mashed potatoes or roasted sweet potatoes for extra comfort.
- Add a fresh green salad with vinaigrette for a light, complete dinner.
- Use leftover roasted chicken and vegetables in wraps, sandwiches, or grain bowls.
Storage and Freezing Instructions
- Refrigerator: Store leftovers in an airtight container for up to 4 days.
- Freezer: Freeze cooked chicken and vegetables separately for up to 3 months. Reheat in the oven at 350°F (175°C) for 15–20 minutes, or microwave until warmed through.
- Tips for best texture: Avoid overcooking when reheating to keep chicken moist and vegetables crisp-tender.

FAQ About Easy One‑Pan Chicken and Broccoli with Peppers & Tomato
Can I use frozen vegetables instead of fresh?
Yes, frozen broccoli and bell peppers can be used. Toss them with a little olive oil and roast for a slightly longer time, about 30–35 minutes, to ensure they aren’t watery. Cherry tomatoes are best fresh, but frozen can work in a pinch if thawed.
Can I make this recipe gluten-free?
Absolutely! This recipe is naturally gluten-free. Just ensure any Dijon mustard used is certified gluten-free. Serve over rice or quinoa for a complete gluten-free meal.
How do I know when the chicken is cooked?
The safest method is to use a meat thermometer. Chicken is done when it reaches 165°F (74°C) internally. The juices should run clear, and the meat should not be pink in the center.
Can I prepare this ahead of time?
Yes, you can chop vegetables and marinate chicken up to a day ahead. Keep them in separate containers and combine just before roasting. This makes weeknight cooking faster.
Can I add other vegetables?
Definitely! Zucchini, asparagus, mushrooms, or even small potatoes work well. Just adjust roasting time for denser vegetables to ensure everything cooks evenly.
