Ingredients

Full List of Ingredients

Every ingredient in this Chicken Zucchini Bake plays a small but mighty role. Here's what you'll need and how each one contributes to the dish's irresistible flavor and texture:

• 2 medium zucchinis – These add a fresh bite and natural moisture. Plus, they’re packed with fiber and nutrients—bonus!

• 1 lb boneless, skinless chicken breast – Lean and high in protein, chicken makes this dish hearty and satisfying.

• 1 tablespoon olive oil – For sautéing the garlic and chicken. It adds depth and a touch of richness.

• 2 cloves garlic, minced – Garlic is the flavor base here—fragrant, savory, and always a welcome aroma in the kitchen.

• 1 teaspoon Italian seasoning – A ready-made blend of herbs (like oregano and basil) that brings everything together.

• Salt & pepper, to taste – The essentials! These help all the other flavors shine.

• 1 cup shredded mozzarella cheese – Melts beautifully for that gooey, cheesy top layer.

• ½ cup grated Parmesan cheese – Salty, nutty, and totally necessary for that extra punch of flavor.

• ½ cup sour cream – Adds a creamy tang that balances the richness of the cheese.

• ¼ cup mayonnaise – Helps bind the sauce while keeping things silky and smooth.

• ½ teaspoon paprika – A touch of warmth and a beautiful hint of color.

• Fresh parsley, chopped – Adds freshness and a pop of green that makes the dish feel finished and festive.

How to Make Chicken Zucchini Bake

This recipe is as simple as it is satisfying. No complicated steps, no fancy tools—just honest ingredients and a few easy steps to pull it all together.

Step-by-Step Instructions

1. Preheat your oven to 375°F (190°C). Lightly grease a medium baking dish and set it aside.

2. Warm the olive oil in a large skillet over medium heat. Once it’s shimmering, toss in the garlic and sauté for about 30 seconds until fragrant.

3. Add the diced chicken to the skillet. Season with salt, pepper, and Italian seasoning. Cook, stirring occasionally, until the chicken is cooked through and no longer pink—about 6–8 minutes.

4. Add in the zucchini, and stir to combine. Let it cook for around 5 minutes until slightly softened but still holding its shape.

5. In a separate bowl, mix together the sour cream, mayo, paprika, and half of both the mozzarella and Parmesan cheeses. (This mixture will become your creamy, dreamy sauce!)

6. Remove the skillet from heat and gently fold in the creamy mixture until everything is well coated.

7. Transfer the contents to your prepared baking dish, spreading it out evenly.

8. Sprinkle the remaining cheese on top to create that irresistible cheesy crust.

9. Bake uncovered for 20–25 minutes or until bubbly and golden around the edges.

10. Optional but delightful: Pop it under the broiler for 2–3 minutes for that perfect browned cheese top.

11. Garnish with fresh parsley, and serve warm. Prepare for the compliments to roll in!
