Easy Italian Chicken Zucchini Bake

Category: Easy Dinners Ready in 30 Minutes or Less

Baked chicken breast pairs beautifully with tender zucchini, savory marinara, and a generous topping of mozzarella and Parmesan. After sautéing onion and garlic for depth, zucchini is cooked just until slightly crisp before being combined with the sauced chicken. Everything is layered in a baking dish, sprinkled with plenty of cheese, and oven-baked until golden and bubbly. This dish makes a hearty, crowd-pleasing meal, perfect for pairing with salads or crusty bread. Fresh herbs can be added for a vibrant finish. Letting it rest before serving ensures cheesy perfection in every bite!

This Easy Italian Chicken and Zucchini Bake is one of those weeknight dinners that disappears fast from the table. It is cozy dairy rich and bubbling with flavor while helping use up extra zucchini in the most crowd pleasing way.

The first time I threw this together was after a busy day when I needed to get dinner going fast. My whole family dug in and now it is requested on repeat especially during zucchini season.

Ingredients

  • Cooked chicken breast: Provides lean protein and makes use of leftovers I usually grab a rotisserie chicken for ease
  • Zucchinies: Bring moisture and a fresh slightly sweet flavor Use medium not oversized ones so they do not get mushy
  • Marinara or Italian tomato sauce: Gives that classic tomatoey backbone To pick a good jar scan for olive oil not soybean oil as one of the first ingredients
  • Shredded mozzarella cheese: Melts into gooey pockets for that pizza vibe Whole milk mozzarella is extra creamy
  • Grated Parmesan cheese: Offers a salty nutty kick Buy a wedge and grate it fresh for best impact
  • Onion and garlic: Pack in the aromatics Use fresh for the most punch
  • Dried Italian seasoning or a homemade blend: Infuses every bite with subtle herbal notes
  • Olive oil: Ties everything together and helps brown the veggies Choose a high quality extra virgin variety
  • Salt and pepper: Are simple essentials Taste as you go so you do not overdo it
  • Fresh parsley or basil as a garnish: Brightens everything up Just a sprinkle at the end

Step-by-Step Instructions

Preheat the Oven:
Before you start assembling anything let your oven heat up fully at 375 F That way your bake cooks evenly and comes out bubbling all the way through
Sauté the Aromatics:
In a skillet pour in olive oil and let it warm over medium heat Toss in your finely chopped onion and the minced garlic Stir often for about five minutes until the onion turns soft and edges slightly golden This step coaxes out all those beautiful flavors that make the kitchen smell mouthwatering
Cook the Zucchini:
Add sliced zucchini to the pan and stir to coat in the onion and garlic mixture Let them sauté for around seven minutes just until they begin to turn tender but are not mushy Sprinkle with salt pepper and half your Italian seasoning to layer in flavor early
Combine Everything:
Spoon the cooked chicken zucchini mixture and marinara sauce into a big bowl Mix thoroughly so everything gets coated in sauce Taste and add a bit more seasoning or salt if it needs it This is your chance to tweak the flavor just right
Layer the Bake:
Lightly oil your baking dish so nothing sticks Spoon half of the chicken zucchini mix into the dish and smooth it out Evenly scatter half the mozzarella and Parmesan cheese on top to start your ooey gooey layers
Finish the Layers:
Add the rest of your chicken and zucchini mixture Next cover the top with the remaining cheese Spread it out so you get bubbly browned cheese edges all around
Bake Until Bubbly:
Slide the dish into your hot oven Let it bake uncovered for twenty five to thirty minutes The cheese should be thoroughly melted golden and some edges might look crispy Your whole house will fill with that classic cheesy Italian aroma
Let It Rest and Garnish:
Take the dish out and leave it to rest for about five minutes This makes it easier to serve neatly Top with fresh parsley or basil if you like to add freshness and color
Serve It Up:
Scoop generous portions onto plates This meal stands alone or goes perfectly with some bread or a green salad on the side

Storage Tips

Cool leftovers completely and store them tightly covered in the fridge They keep fresh for three days You can freeze portions as well Just thaw overnight in the fridge and reheat in the oven at 325 F with a little extra cheese sprinkled on top

Ingredient Substitutions

If you are out of chicken use leftover turkey or cooked ground turkey instead Eggplant can replace some or all of the zucchini for a more classic parm flavor If dairy is an issue swap in your favorite plant based shredded cheese blends

Serving Suggestions

This bake is hearty enough alone but crusty fresh bread makes it extra filling A simple arugula salad dressed with olive oil and lemon brings a peppery green pop to the plate For a celebratory touch a glass of red wine complements everything
