Mouthwatering Chicken Zucchini Bake

As seen in Satisfying Entrées for Every Table.

You’ll bite into slices of juicy chicken and zucchini covered in melty Parmesan, cheddar, and mozzarella. That creamy sauce? It’s just sour cream or Greek yogurt, boosted with fresh basil, oregano, onion powder, and a punch of garlic. The layers bake till the cheese on top is golden and bubbling. Sprinkle with parsley and you’ve got a cheesy, satisfying dish that’s super easy but looks and tastes fancy.

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.

What You'll Need

→ For the Bake

01 1 cup sour cream or Greek yogurt
02 1 tablespoon olive oil
03 3 medium zucchinis, cut into quarter-inch rounds
04 2 large boneless skinless chicken breasts, around 1 pound
05 1/2 cup grated Parmesan
06 1 teaspoon dried oregano
07 Salt and black pepper, use how you like
08 2 cloves garlic, minced up
09 1 teaspoon dried basil
10 1 cup shredded mozzarella
11 1 cup shredded cheddar

→ For the Seasoning

12 1/2 teaspoon onion powder
13 1 tablespoon fresh parsley, chopped up (makes a nice finish if you want)
14 1 teaspoon garlic powder

Step-by-Step Directions

Step 01

Let it sit a bit once it’s out of the oven. If you’re in the mood, scatter some parsley on top before bringing it to the table.

Step 02

Slide the dish into your hot oven and bake for 25 to 30 minutes. You want the cheese bubbling and browned, and the zucchini fork-tender.

Step 03

Drop on the rest of your mozzarella and all of the cheddar so you get that cheesy finish.

Step 04

Pile the cooked chicken across the zucchini rounds. Then pour your cheesy sauce all over to cover everything.

Step 05

Spread the zucchini slices out along the bottom of your oiled baking dish.

Step 06

Mix up your sour cream or yogurt, Parmesan, half the mozzarella, dried oregano, dried basil, and a sprinkle of salt and pepper until the sauce looks smooth and creamy.

Step 07

Using that same pan, toss in minced garlic and cook for just half a minute to bring out its smell.

Step 08

Add oil to your skillet on medium, then throw in your seasoned chicken. Cook until golden and cooked through, about 5 to 7 minutes. Lift out and stash aside.

Step 09

Cut zucchini into thick coins, about a quarter inch wide, and keep them handy.

Step 10

Cut the chicken into strips about an inch wide or just chunk it up bite-size. Sprinkle with salt, pepper, garlic powder, and some onion powder.

Step 11

Fire up your oven to 375°F (190°C) and wipe some oil on a 9x9-inch (or similar) casserole dish.

Helpful Notes

  1. If you cut your zucchini slices about the same size, you won’t get some mushy and some crunchy bits.
  2. For a lower-calorie option, swap in Greek yogurt for sour cream.
