Step-by-Step to an Easy Bake

Get ready for the easiest dinner you’ll make all week.

Part 1: Prep and Season

Preheat Oven: Preheat your oven to 400°F (200°C).
Combine Ingredients: In a large bowl, combine the cubed chicken, chopped zucchini, and halved cherry tomatoes.
Season Well: Drizzle the olive oil over the ingredients in the bowl. Sprinkle with the Italian seasoning, garlic powder, salt, and pepper. Toss everything together until the chicken and vegetables are evenly coated in the oil and seasonings.

Part 2: Arrange and Bake

Spread in Dish: Pour the seasoned chicken and vegetable mixture into a 9×13 inch baking dish. Spread it out into a single, even layer. It’s important not to overcrowd the dish so everything cooks evenly.
Top with Cheese: Sprinkle the shredded mozzarella cheese evenly over the top of the chicken and vegetables. Finish with a sprinkle of grated Parmesan cheese.
Bake to Perfection: Place the baking dish in the preheated oven. Bake for 20-25 minutes, or until the chicken is cooked through, the zucchini is tender, and the cheese is melted, bubbly, and starting to turn golden brown on top.
Garnish and Serve: Remove from the oven and let it rest for a few minutes. Garnish with fresh chopped parsley if desired, and serve hot.

Tips for the Perfect Chicken Bake

Uniform Size is Key: Try to cut your chicken and zucchini into similar-sized, bite-sized pieces. This ensures that everything cooks at the same rate and the dish is easy to eat.
Add More Veggies: Feel free to add other quick-cooking vegetables to the mix. Sliced bell peppers, onions, or mushrooms would all be delicious additions.
For a Saucy Version: If you prefer a saucier dish, you can add ½ cup of your favorite marinara sauce to the chicken and vegetable mixture before topping with cheese.
Storage and Reheating: Leftovers are fantastic! Store them in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave or in the oven at 350°F until warmed through.
