Fuel Up: The Ingredients You’ll Need
For the Chicken and Zucchini:
- 1.5 lbs boneless, skinless chicken breasts, cut into 1-inch cubes
- 2 medium zucchini, diced
- 1 medium onion, chopped
- 2 cloves garlic, minced
- 1 tablespoon olive oil
- 1 teaspoon Italian seasoning
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
For the Creamy Cheese Sauce:
- 8 oz cream cheese, softened

- 1 cup shredded mozzarella cheese, divided
- 1/4 cup grated Parmesan cheese
- 1/4 teaspoon garlic powder
- Pinch of red pepper flakes (optional)
Let’s Bake: Step-by-Step Instructions
Prep the Chicken and Veggies:
- Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish. This is important – no one likes a stuck casserole!
- In a large skillet, heat olive oil over medium heat. Add the chopped onion and cook until softened, about 5 minutes.
- Add the minced garlic and cook for another minute until fragrant. Don’t let it burn!
- Add the cubed chicken to the skillet and cook until browned on all sides. It doesn’t need to be cooked all the way through at this point.
- Stir in the diced zucchini, Italian seasoning, salt, and pepper. Cook for about 5-7 minutes, or until the zucchini is slightly tender.
Make the Creamy Cheese Sauce:
- In a large bowl, combine the softened cream cheese, sour cream, milk, 1/2 cup of the mozzarella cheese, Parmesan cheese, garlic powder, and red pepper flakes (if using).
- Mix well until smooth and creamy. A few lumps are okay, they’ll melt in the oven.
Assemble and Bake:
- Pour the chicken and zucchini mixture into the prepared baking dish.
- Spread the creamy cheese sauce evenly over the chicken and zucchini.
- Sprinkle the remaining 1/2 cup of mozzarella cheese over the top.
- Bake for 25-30 minutes, or until the cheese is melted, bubbly, and lightly golden brown.
- Let the Chicken Zucchini Bake rest for 5-10 minutes before serving. This allows the sauce to set up a bit.
Variations and Swaps: Make it Your Own!
This Chicken Zucchini Bake is super versatile! Feel free to adjust it to your liking. Here are some ideas:
- Vegetables: Add other veggies like bell peppers, mushrooms, or spinach.
- Cheese: Experiment with different cheeses like cheddar, provolone, or Monterey Jack.
- Spice: Add a dash of hot sauce or cayenne pepper for extra heat.
- Herbs: Fresh herbs like basil or parsley add a burst of flavor.
- Low Carb: If you’re watching your carbs, consider using almond flour to thicken the sauce slightly or try a Creamy Low Carb Chicken Casserole.
Pro Tips for the Perfect Bake
Here are a few tricks I’ve learned over the years to make sure your Chicken Zucchini Bake turns out amazing every time:
- Don’t overcrowd the skillet: Cook the chicken in batches if necessary to ensure it browns properly. Overcrowding will steam the chicken instead of browning it.
- Use softened cream cheese: This will make the sauce much smoother and easier to mix.
- Grate your own cheese: Pre-shredded cheese often contains cellulose, which can prevent it from melting as smoothly.
- Let it rest: Allowing the bake to rest for a few minutes after baking helps the sauce thicken and makes it easier to serve.
What to Serve With Chicken Zucchini Bake

- Roasted Vegetables: Roasted broccoli, asparagus, or Brussels sprouts are healthy and delicious.
- Rice or Quinoa: If you want to add some extra carbs, rice or quinoa are great options.
