What Ingredients You Will Need

This cheesy chicken zucchini parmesan bake is built on easy-to-find, everyday ingredients that come together for one seriously comforting meal. Here’s what you’ll need and why each one matters.

• Chicken breast or thighs, cooked and shredded (about 2 cups/300g) – Use rotisserie chicken for speed, or bake your own for extra juiciness.
• Zucchini, sliced into thin rounds (2 medium, about 12oz/340g) – Adds moisture and sneaks in those veggies! Go with firm, shiny zucchini for best texture.
• Marinara sauce (2 cups/480ml) – Use your favorite jarred brand, or homemade if you have it. I like Rao’s or a simple homemade tomato-basil sauce.
• Mozzarella cheese, shredded (1 ½ cups/170g) – For that classic melty cheese pull. Whole-milk mozzarella melts best.
• Parmesan cheese, grated (½ cup/50g) – Adds salty, nutty depth. Use freshly grated for the best flavor.
• Provolone cheese, shredded or sliced (½ cup/50g) – Optional, but I love the sharp bite it brings. Substitute with extra mozzarella if needed.
• Italian-style breadcrumbs (½ cup/60g) – For a golden, crispy topping. Panko also works, just add a pinch of Italian seasoning.
• Egg, lightly beaten (1 large) – Helps bind everything together.
• Garlic, minced (2 cloves) – Fresh is best, but jarred works in a pinch. Adds a savory punch.
• Olive oil (2 tablespoons/30ml) – For sautéing the zucchini and boosting richness.
• Fresh basil or parsley, chopped (2 tablespoons/10g) – For a pop of freshness at the end. Dried Italian herbs work if that’s what you have.
• Salt and black pepper – To taste. I start with ½ teaspoon (3g) each and adjust as I go.
• Red pepper flakes (optional, ¼ teaspoon/1g) – If you like a little kick.

Substitutions & Tips: You can swap in yellow squash for some or all of the zucchini, or use a rotisserie chicken shortcut. If gluten-free is needed, use gluten-free breadcrumbs. For a lower-fat version, reduce the cheese by half or use part-skim mozzarella. Dairy-free? Try vegan mozzarella and parmesan shreds (I’ve used Violife in a pinch and it melts well!). If you’re out of eggs, a tablespoon of Greek yogurt will help bind the mix in a similar way.

It’s one of those recipes where you can mix and match depending on what’s in your fridge, so don’t stress if you need to improvise.

Equipment Needed

You don’t need a fancy kitchen set-up for this cheesy chicken zucchini parmesan bake—just a few basics and maybe a little muscle for grating cheese. Here’s what I use:

• 9×13-inch (23x33cm) baking dish – Glass, ceramic, or metal all work. If you only have a smaller dish, you can bake in batches or halve the recipe.
• Large skillet or sauté pan – For quickly cooking the zucchini and garlic. A nonstick pan makes cleanup easier, but cast iron gives a nice sear.
• Mixing bowls – At least two: one for mixing the filling, one for tossing the breadcrumb topping.
• Whisk or fork – For beating the egg.
• Sharp knife and cutting board – Slicing zucchini and chopping herbs goes faster with a good knife.
• Box grater or microplane – For grating cheese and garlic if not pre-shredded.
• Aluminum foil – To tent the bake if the cheese browns too quickly.

If you don’t have a 9×13 dish, two 8×8 pans or even a large ovenproof skillet will do. For the cheese, pre-shredded is fine (though freshly grated always melts better). When I first made this, I used a $1 thrift store baking dish, and it worked just fine. Just be sure to give everything a good clean before and after—melted cheese can be stubborn, so a soak in hot soapy water helps.

Preparation Method

1. Preheat and Prep: Heat your oven to 400°F (200°C). Lightly grease a 9×13-inch (23x33cm) baking dish with olive oil or nonstick spray. This keeps everything from sticking and helps the cheese crisp up at the edges.
2. Cook the Zucchini: Warm 1 tablespoon (15ml) olive oil in a large skillet over medium-high heat. Add the sliced zucchini and a pinch of salt. Sauté for 5-7 minutes, stirring occasionally, until the zucchini softens and starts to brown. Toss in the minced garlic for the final 1-2 minutes, letting it get fragrant but not burnt. (If the pan looks dry, add a splash more olive oil.) Drain off any excess liquid—the less water, the better your bake sets up.
3. Mix the Chicken Filling: In a large bowl, combine the cooked shredded chicken, sautéed zucchini and garlic, 1 cup (240ml) marinara sauce, 1 cup (115g) mozzarella, ¼ cup (25g) parmesan, and the beaten egg. Add a generous grind of black pepper, a pinch of salt, and red pepper flakes if using. Stir in half the chopped basil or parsley for extra flavor. The mix should be well-coated but not soupy.
4. Layer the Bake: Spread half of the remaining marinara sauce (½ cup/120ml) in the bottom of your prepared baking dish. Spoon the chicken-zucchini mixture over the sauce and spread it out evenly. Top with the rest of the marinara, then sprinkle the remaining mozzarella, parmesan, and all the provolone over the top.
5. Add the Breadcrumb Topping: In a small bowl, toss the Italian breadcrumbs with 1 tablespoon (15ml) olive oil and a pinch of salt. Sprinkle this mixture evenly over the cheese layer. (Breadcrumbs will turn golden and crisp in the oven—don’t skip this step!)
6. Bake: Place the dish in the center of the oven. Bake for 25-30 minutes, or until the cheese is bubbling and the topping is golden brown. If the top gets too brown before the center is hot, tent with foil for the last 10 minutes.
7. Cool and Finish: Let the cheesy chicken zucchini parmesan bake rest for 5-10 minutes after baking. This helps it set and makes serving easier. Sprinkle with remaining fresh basil or parsley before slicing.

Notes & Troubleshooting: If your bake is watery, it’s likely the zucchini wasn’t sautéed long enough or the chicken held a lot of moisture. Next time, pat the zucchini dry after sautéing and use cooked chicken that isn’t too juicy. For a crispier topping, broil for 2-3 minutes at the end—but watch closely! And remember, it always smells even better than it looks when you crack open that oven.

Cooking Tips & Techniques

After several rounds of tweaking, I’ve landed on a few tricks that make this cheesy chicken zucchini parmesan bake turn out perfect every time:

• Drain the Zucchini Well: Zucchini holds a ton of water. Give it a good sauté and, if you have time, let the cooked slices rest on a paper towel to wick away extra moisture. Otherwise, your bake might come out a little soupier than you’re hoping.
• Layer the Cheese Thoughtfully: Don’t put all the cheese in one spot. I like to mix some into the filling and save the rest for a gooey, golden topping. The combo of mozzarella for melt, parmesan for flavor, and provolone for a little punch is my go-to, but play around here!
• Breadcrumbs Need Olive Oil: Tossing the breadcrumbs with oil before adding them on top is crucial. Dry crumbs just don’t brown up the same way. If you’re out of olive oil, melted butter works too.
• Taste As You Go: The filling should be flavorful before it even hits the oven. Give it a taste—add more salt, pepper, or herbs if it seems flat. I learned this the hard way after one bland batch early on. Never again!
• Don’t Overbake: Once the cheese is bubbling and golden, you’re done. Overbaking can dry out the chicken and make the zucchini mushy.

My favorite way to multitask: prep the filling while the zucchini sautés, and get the breadcrumb topping ready as the bake cooks. If you’re prepping ahead, assemble everything (except the breadcrumbs) and refrigerate until you’re ready to bake—just add the topping fresh so it stays crisp. And don’t be afraid to get creative; sometimes I sneak in a handful of spinach or leftover roasted veggies, and it always turns out delicious.

Variations & Adaptations

This dish is super flexible—here are a few ways to make it your own (plus my favorite twist!):

• Low-Carb/Keto: Skip the breadcrumbs entirely or use crushed pork rinds for a crunchy, carb-free topping. You can also reduce the marinara sauce if you want fewer carbs.
• Vegetarian: Leave out the chicken and double up on zucchini, or add a can of drained white beans for extra protein. Eggplant makes a hearty addition too.
• Seasonal Veggies: Try adding thin-sliced yellow squash, mushrooms, or spinach to boost the veggie content. In fall, I sometimes toss in roasted butternut squash cubes—so cozy!
• Dairy-Free: Use dairy-free cheese shreds and a flax egg (1 tablespoon ground flaxseed + 2.5 tablespoons water) to keep everything together. I’ve made this for a lactose-intolerant friend and it was still a hit.
• Personal Favorite: Sometimes, I stir in a spoonful of pesto to the chicken-zucchini filling for a herby flavor boost. It’s a game-changer!

For different cooking methods, you can assemble the bake in individual ramekins for dinner parties (they cook a bit faster) or prep it in a slow cooker—just layer, cover, and cook on low for 4-5 hours. And if you need to avoid gluten, gluten-free or almond flour breadcrumbs work just as well for the topping.

Serving & Storage Suggestions

This cheesy chicken zucchini parmesan bake is best served hot and bubbling straight from the oven. I usually let it cool for about 10 minutes so it slices cleanly and the flavors settle in. For a pretty presentation, garnish with extra fresh basil or a sprinkle of parmesan.

It pairs perfectly with simple sides—think a crisp green salad, garlic bread, or a bowl of pasta if you’re feeling extra hungry. For drinks, a glass of chilled white wine or sparkling water with lemon is just right.

To store leftovers, let the bake cool completely, then cover and refrigerate in the baking dish or transfer to airtight containers. It keeps well in the fridge for up to 4 days. For longer storage, portion into freezer-safe containers and freeze for up to 2 months. Thaw overnight in the fridge before reheating.

Reheat individual slices in the microwave (covered, about 2-3 minutes), or warm the whole dish in a 350°F (175°C) oven until heated through. If you want to crisp the topping again, broil for a minute or two at the end. Honestly, the flavors get even better the next day as everything melds together—leftovers are kind of a treat!

Frequently Asked Questions

Can I make this cheesy chicken zucchini parmesan bake ahead of time?

Yes! You can assemble the entire bake (except the breadcrumb topping), cover, and refrigerate for up to 24 hours. Add the breadcrumbs right before baking for the best crunch.

What’s the best way to shred chicken quickly?

If you’re short on time, use two forks to pull apart cooked chicken breasts or thighs. Or, toss warm cooked chicken into a stand mixer with the paddle attachment for super fast shredding!

How can I make this recipe gluten-free?

Just swap regular breadcrumbs for gluten-free ones, or use almond flour mixed with Italian herbs for a similar crunch.

Can I use pre-cooked rotisserie chicken?

Absolutely. Rotisserie chicken is a huge time saver—just remove the skin and bones, then shred or chop before mixing with the other ingredients.

What should I do if my bake turns out watery?

This usually happens if the zucchini wasn’t drained well. Next time, sauté the zucchini longer and let it rest on paper towels before mixing. You can also salt the raw slices and let them sit for 10 minutes to draw out extra moisture.
