About the Ingredients

4 boneless, skinless chicken breasts (about 1.5 lbs / 680g)

Cut into 1-inch pieces for even cooking. You can also use chicken thighs for more flavor.

2 cups (250g) broccoli florets

Fresh or frozen (thawed). If using frozen, pat dry to avoid extra moisture.

2 cups (250g) baby potatoes, halved

Any small potato works. For a lower-carb option, swap with cauliflower florets.

1 red bell pepper, sliced

Adds color and sweetness. Use any color you like.

1 yellow onion, cut into wedges

Red onion is a great substitute for a milder flavor.

3 tablespoons (45ml) olive oil

Extra virgin or regular both work. For a lighter option, use avocado oil.

2 cloves garlic, minced

Fresh garlic is best, but 1/2 teaspoon garlic powder works in a pinch.

1 teaspoon dried oregano

Italian seasoning or thyme are good substitutes.

1 teaspoon paprika

Smoked paprika gives a deeper flavor if you have it.

1/2 teaspoon salt

Adjust to taste. Sea salt or kosher salt both work.

1/4 teaspoon black pepper

Freshly ground is best for flavor.

2 tablespoons (30g) grated Parmesan cheese (optional)

For a cheesy finish. Nutritional yeast is a dairy-free alternative.

Tips & Tricks

• Cut ingredients into similar-sized pieces so they cook evenly.
• Don't overcrowd the pan – use a large sheet pan or two if needed to avoid steaming.
• Pat the chicken dry before seasoning to help it brown better.

Step-by-Step Instructions

1. Preheat Oven

Preheat your oven to 425°F (220°C). Place a large sheet pan inside to heat up – this helps everything cook faster and get a nice sear.

2. Prep Ingredients

While the oven heats, cut the chicken into 1-inch pieces, chop the broccoli, halve the potatoes, slice the bell pepper, and cut the onion into wedges. Aim for similar sizes so everything cooks evenly.

3. Mix Seasoning

In a small bowl, combine the olive oil, minced garlic, oregano, paprika, salt, and pepper. Whisk until well blended.

4. Toss Everything

In a large bowl, add the chicken and all the vegetables. Pour the seasoning mixture over and toss until everything is evenly coated.

5. Spread on Pan

Carefully remove the hot sheet pan from the oven and spread the mixture in a single layer. Make sure the chicken pieces are not crowded – leave space between them for browning.

6. Roast

Place the pan in the oven and roast for 20-25 minutes, or until the chicken is cooked through (internal temperature reaches 165°F / 74°C) and the vegetables are tender and starting to caramelize. The potatoes should be easily pierced with a fork.

7. Add Cheese (Optional)

If using Parmesan, sprinkle it over the hot dish during the last 5 minutes of roasting. Let it melt and turn golden.

8. Rest and Serve

Remove from the oven and let rest for 5 minutes. This allows the juices to redistribute. Serve warm and enjoy!

Delicious Variations

Mediterranean

Swap chicken for salmon fillets, add cherry tomatoes and olives, use oregano and lemon zest.

Spicy

Add 1 teaspoon chili flakes or a dash of cayenne pepper to the seasoning mix.

Teriyaki

Replace the seasoning with 1/4 cup teriyaki sauce and add pineapple chunks.
