You can count on this Chicken Zucchini Bake any busy night. It's got juicy chicken, loads of stretchy cheese, zucchini, and a creamy sauce with a little tang. Everything gets tossed into one bubbling dish. My folks always ask for seconds. I love it because it's quick and the stuff is usually just sitting in my fridge already.
I threw this together the first time after our garden zucchini took over that one summer. Now, every time I whip it up, the house smells amazing and people start wandering into the kitchen before I can even get plates out.
Inviting Ingredients
- Olive oil: Helps keep chicken and veggies tender plus adds subtle flavor. Extra virgin is awesome if you’ve got it.
- Cheddar cheese: Makes the whole thing richer and a bit tangy. Sharp cheddar crumbles best if you grate it fresh.
- Garlic and dried herbs like oregano and basil: Bring warm, homey flavors usually found in Italian pasta bakes.
- Chicken breast: Lean protein that keeps you full. Try to get fresh, pinkish ones without skin or bones.
- Sour cream or Greek yogurt: Gives that creamy, slightly tangy sauce. Full-fat makes it richer.
- Zucchini: Adds crunch and a bit of sweetness. Grab small or medium firm ones with no soft spots.
- Mozzarella cheese: That stretchy melt is a must. Shred your own to get the best gooey texture.
- Parsley for garnish: Totally optional, but it makes everything look fresher and adds color.
- Parmesan cheese: Bumps up the savory edge and gets you a golden, crunchy finish.
- Garlic powder and onion powder: Double up the flavor with these easy shakers for deeper taste.
Step-by-Step Directions
- Finish and Serve:
- Pull the bake out and let it chill for a bit so everything firms up. Shower parsley over the top, then dig in.
- Bake It:
- Pop the pan in that hot oven for about 25 or 30 minutes. Cheese should be bubbling and a little browned and the zucchini will be fork-tender.
- Top with Cheese:
- Spread on all the cheddar and the rest of the mozzarella.
- Layer the Bake:
- Press zucchini rounds to fill the bottom, pile on chicken, and blanket with the stiry sauce.
- Mix Up the Sauce:
- Grab a bowl and stir together your sour cream, half the mozz, Parmesan, both herbs, and a pinch of salt and pepper until smooth.
- Sauté Garlic:
- Toss in your garlic and let it bubble for about 30 seconds to smell great.
- Sear the Chicken:
- Warm oil in a skillet, then brown chicken pieces a few minutes per side. Pull them when they’re just cooked through.
- Slice the Zucchini:
- Chop up your zucchini into even little circles, about a quarter-inch thick.
- Season the Chicken:
- Cube up your chicken and rub them with garlic powder, onion powder, salt, and pepper for flavor everywhere.
- Preheat and Prepare Pan:
- Set the oven to 375 F. Give your 9x9 pan a swipe of oil or butter so it cleans up easy.

Parmesan is my top pick for this one. It’s salty and nutty and gives the best flavor. The golden edges get super crispy and sticky, which was always the first thing everyone tried to steal at my family’s dinner table. I remember us gathering around the oven, just waiting for that cheese to bubble up.
Storing Made Easy
Stick leftovers in the fridge (covered) for up to three days. Warm up portions in the oven or microwave and it tastes awesome. If you want to freeze, cool it down first, wrap it tight, and label it. Let it thaw in the fridge and polish it off within a month for the best taste.
Swaps and Shortcuts
No sour cream? Greek yogurt is perfect instead—same creamy texture and a bit of zip. Rotisserie chicken saves you time, too. You can use yellow squash if you like or split with zucchini for extra color.

Fun Pairings
Serve this with a leafy salad or oven-roasted broccoli for something fresh. Want it heartier? Pile on some warm rice or fluffy quinoa. And hey, garlic bread is a total crowd-pleaser for mopping up the sauce.
