Here's my go-to comfort meal for busy evenings: a creamy chicken and zucchini dish that’s all things cozy and breezy. You'll get soft chicken, loads of gooey cheese, zucchini, and a zingy cream sauce baked all together. My family happily clears their plates, and I love how it comes together in a snap with stuff I usually have on hand.
The first time I tried this, my kitchen was packed with late summer zucchini. Now whenever it goes in the oven, that irresistible smell pulls everyone into the kitchen before it’s even ready.
Delicious Ingredients
- Cheddar cheese: Gives richness and a tangy twist. Try a sharp block for big flavor
- Mozzarella cheese: For ultimate melt and classic stretch. Freshly shredded is best if you can
- Chicken breast: Lean and hearty. Boneless, skinless, and plump pieces work great
- Parmesan cheese: Adds savory oomph and makes the cheesy crust pop
- Olive oil: Keeps it moist and sneaks in extra flavor. Go with extra virgin if possible
- Zucchini: Fresh and crunchy. Pick firm, small-to-medium ones that look healthy
- Sour cream or Greek yogurt: The key to a rich, tangy sauce. Choose full fat for a dreamy texture
- Garlic powder and onion powder: Kick up the savory notes
- Garlic plus dried oregano and basil: Bring warm, herb-filled goodness every time
- Parsley (for topping): Optional, but makes it look fancy and adds a fresh finish
Easy Step-by-Step
- Finish and Serve:
- Let it sit a few minutes after baking to firm up. Toss some chopped parsley on top if you’ve got it for a splash of green
- Bake It:
- Move the dish into your hot oven. Bake for around twenty-five to thirty minutes. The cheese should be bubbly and browned, and a fork should slip right through the zucchini
- Top with Cheese:
- Layer with all the cheddar and whatever mozzarella you saved
- Layer the Bake:
- Arrange zucchini slices to cover the bottom. Add your chicken on top so it’s all spread out. Pour the creamy sauce over everything
- Mix Up the Sauce:
- In a bowl, mix together the sour cream, Parmesan, half your mozzarella, dried basil, oregano, salt, and pepper. Stir until it’s all creamy and blended
- Sauté Garlic:
- Add minced garlic to your pan and cook for about half a minute until it smells awesome
- Sear the Chicken:
- In a skillet with olive oil on medium, put the chicken in, cook both sides until browned and just done (about five to seven minutes), then set aside
- Slice the Zucchini:
- Chop your zucchini into rounds around a quarter inch thick so they’ll cook evenly
- Season the Chicken:
- Cut chicken into little bites so it cooks fast. Sprinkle on salt, pepper, garlic powder, and onion powder
- Preheat and Prepare Pan:
- Kick your oven up to 375°F. Lightly oil a roughly 9x9-inch baking dish so the food doesn’t stick

I can’t get enough of the Parmesan in here. That salty, nutty boost makes this way better than boring baked chicken, plus those crunchy brown cheesy bits on the edge are gold. Growing up, we’d all huddle around the oven, hoping to snag those crispy pieces first.
Keeping it fresh
This keeps well covered in the fridge up to three days. For leftovers, just heat up what you want in the microwave or pop small portions in the oven until hot. After freezing, let it cool off fully, then wrap it up tight and label. Thaw in the fridge and finish within a month for tastiest results.
Swap ideas
If you’re out of sour cream, grab Greek yogurt—it’s just as creamy and tangy. Use pre-cooked rotisserie chicken if you don’t feel like cooking. Try swapping in yellow squash for the zucchini for a new spin or mix them up for more color.

Serving ideas
This creamy chicken bake goes awesome with a crisp green salad or some roasted broccoli. Want to bulk it up? Add a scoop of rice or fluffy quinoa next to it. Garlic bread is perfect for all that saucy goodness.
Backstory
Baked meals like this are favorites across homes in the US—easy, cozy, and full of flavor. Mixing up creamy sauce, baked chicken, and mild veggies is a total throwback to classic Midwest or Southern comfort food. Yet thanks to all the zucchini and lean chicken, it still feels pretty modern and fresh.
Common Questions
- → Can I use Greek yogurt instead of sour cream?
Totally! Greek yogurt swaps in perfectly and gives the sauce a fresh tang without losing that creamy texture.
- → How can I prevent the bake from becoming watery?
Stick with thicker zucchini slices and don’t bake it too long. If you want, salt the zucchini a bit, dab it with a towel, then add it in.
- → Is it possible to make this dish ahead of time?
For sure! Put it all together, stash it in the fridge, and pop it in the oven before you eat—keeps that amazing cheesy finish.
- → What other cheeses can be used?
Try Monterey Jack, provolone, or go with any good melty cheese you like for a switch-up in flavor.
- → Can I add other vegetables?
Yep! Toss in bell peppers, spinach, or mushrooms for extra taste and color anytime.
- → Is this dish gluten-free?
It sure is! All the stuff in here is naturally gluten-free, so you don’t have to worry.
