Creamy Garlic Chicken and Zucchini is an easy one-pan dinner that takes simple ingredients and turns them into something rich, comforting and full of flavor.
Tender pieces of chicken are browned first so they develop a golden crust. Fresh zucchini is then cooked in the same skillet, picking up all the flavor left behind by the chicken.
Everything is finished in a creamy garlic-Parmesan sauce that is perfect for spooning over rice, pasta or mashed potatoes.
It’s also an excellent summer dinner because zucchini is readily available throughout the warmer months. If you have several zucchini sitting in your refrigerator and aren’t sure how to use them, this recipe requires two at once.
Why This Chicken and Zucchini Recipe Works
One-pan meals are useful for busy evenings because they minimize cleanup without sacrificing flavor.
Instead of boiling vegetables separately or preparing an extra sauce pan, all the important components of this recipe are cooked in the same skillet.
Browning the chicken first creates small caramelized pieces on the bottom of the pan. When broth is added later, those browned pieces dissolve into the sauce and provide extra flavor.
Don’t Overcook Your Zucchini
One of the biggest mistakes when cooking zucchini is leaving it in the pan for too long.
Zucchini contains a lot of water. As it cooks, it releases moisture and gradually becomes softer.
For this recipe, you want tender zucchini with lightly browned edges rather than mushy zucchini disappearing into the sauce.
Cooking it separately before adding the cream makes the texture much easier to control.
Can You Use Chicken Thighs?
Absolutely.
Boneless skinless chicken thighs have slightly more fat than chicken breasts, which makes them very flavorful and forgiving.
You can use either depending on what you have available.

Ingredients
- 1½ pounds boneless skinless chicken breast, sliced
- 2 medium zucchini, sliced into half-moons
- 1 tablespoon olive oil
- 1 tablespoon butter
- 4 garlic cloves, minced
- ¾ cup chicken broth
- ½ cup heavy cream
- ½ cup freshly grated Parmesan cheese
- 1 teaspoon Italian seasoning
- ½ teaspoon salt
- ¼ teaspoon black pepper
- ¼ teaspoon red pepper flakes, optional
- 2 tablespoons fresh parsley
How to Make Creamy Garlic Chicken and Zucchini
Step 1: Season the Chicken
Pat the chicken dry.
Season it evenly with salt, black pepper and Italian seasoning.
Drying the surface helps the chicken brown rather than steam.
Step 2: Brown the Chicken
Heat olive oil in a large skillet over medium-high heat.
Add the chicken in a single layer.
Avoid overcrowding the pan. Cook in two batches if necessary.
Cook for approximately 3 to 4 minutes per side depending on the size of your pieces.
Transfer the browned chicken to a plate.
It doesn’t need to be completely cooked yet because it will finish cooking in the sauce.
Step 3: Cook the Zucchini
Add butter to the skillet.
Arrange zucchini slices in the pan.
Cook for approximately 2 to 3 minutes before stirring.
Allowing them to remain against the hot surface helps create lightly browned edges.
Continue cooking until tender but still firm.
Step 4: Add Garlic
Add minced garlic.
Cook for approximately 30 seconds while stirring.
Garlic burns quickly, so don’t leave it unattended.
Step 5: Build the Sauce
Pour chicken broth into the skillet.
Use a wooden spoon to scrape the browned pieces from the bottom.
Reduce the heat to medium-low.
Add heavy cream and Parmesan.
Stir until the cheese has melted into the sauce.
Step 6: Finish the Chicken
Return the chicken and any accumulated juices to the pan.
Simmer gently for several minutes until the chicken is completely cooked and the sauce has thickened.
The chicken should reach an internal temperature of 165°F or 74°C.
Finish with fresh parsley and optional red pepper flakes.
How to Thicken the Sauce
The Parmesan should naturally thicken the cream sauce.
If you want it even thicker, simmer it uncovered for another minute or two.
Avoid boiling cream sauce aggressively because high heat can cause it to separate.
Recipe Variations
Chicken, Zucchini and Mushrooms
Sauté sliced mushrooms before adding the zucchini.
Add Spinach
Stir fresh spinach into the finished sauce and let it wilt for one minute.
Add Sun-Dried Tomatoes
Sun-dried tomatoes provide acidity and extra savory flavor.
Make It Spicier
Increase the red pepper flakes or add a small amount of cayenne.

Storage and Reheating
Refrigerate leftovers in an airtight container for up to three days.

Place the leftovers in a skillet over low heat and add a tablespoon or two of broth if the sauce has become too thick.
Frequently Asked Questions
Can I use chicken thighs?
Yes. Boneless skinless chicken thighs work perfectly.
Can I use milk instead of heavy cream?
You can, but the sauce will be much thinner. Half-and-half is a better lighter substitute.
Why did my zucchini become mushy?
It was likely cooked for too long or at too low a temperature.
Can mushrooms be added?
Yes. Mushrooms work particularly well with the creamy garlic sauce.
Is this recipe gluten-free?
The main ingredients are naturally gluten-free, but always check packaged broth, seasonings and Parmesan labels if you’re cooking for someone who must avoid gluten.
