Preparation Phase & Tools to Use
Before diving into this delicious recipe, it’s essential to prepare your kitchen and gather all necessary tools. Start by preheating your oven to 375°F (190°C). Greasing your 9×13-inch baking dish is crucial to prevent sticking and ensure easy serving. Also, having a good-quality skillet for sautéing your onions and garlic will make a significant difference in flavor; a non-stick skillet is ideal.
Make sure you have a large mixing bowl for combining all the ingredients. In addition, have a pot ready for boiling your potatoes and a knife for chopping your veggies. Gather your utensils like a spatula for mixing, and a ladle for serving. Having everything prepared will streamline the cooking process, making it smoother and more enjoyable.

Ingredients
- 2 cups cooked chicken breast, diced or shredded
- 3 cups potatoes, peeled and cubed
- 2 cups broccoli florets (fresh or thawed if frozen)
- 1 cup green peas (optional)
- 1 small onion, finely chopped
- 3 cloves garlic, minced
- 2 cups shredded cheddar cheese, divided
- 0.5 cup grated mozzarella cheese
- 1 can (10.5 oz) cream of chicken soup
- 0.5 cup sour cream
- 0.5 cup milk
- 0.5 teaspoon paprika
- 0.5 teaspoon garlic powder
- 0.5 teaspoon onion powder
- Salt and pepper to taste
- 2 tablespoons olive oil or butter
- Fresh parsley for garnish (optional)
Instructions
Step 1: Preheat and Prepare
Start by preheating your oven to 375°F (190°C). This step is crucial as it ensures that your casserole cooks evenly once it’s ready to go in the oven. While your oven is heating up, take your 9×13-inch baking dish and give it a good grease with olive oil or butter to prevent your delicious casserole from sticking.
Step 2: Boil the Potatoes
Place the peeled and cubed potatoes into a pot of salted water and bring it to a boil. Cook the potatoes for about 8–10 minutes until they are just tender; you want them firm enough to hold their shape in the casserole. After they’re done, drain them and set them aside to cool slightly before mixing with the other ingredients.
Step 3: Sauté the Onion and Garlic
In a skillet over medium heat, add your olive oil or butter, heating it until shimmering. Toss in the finely chopped onion and let it sauté for about 3-4 minutes until translucent. The aroma of the cooking onion will begin to fill your kitchen, adding a beautiful base flavor to the dish. Following that, add in the minced garlic and continue to sauté for another minute, stirring frequently to prevent burning.
Step 4: Combine the Ingredients
In a large mixing bowl, combine the cooked chicken, boiled potatoes, fresh broccoli florets, and optional green peas. Add the sautéed onion and garlic mixture, along with 1.5 cups of the shredded cheddar cheese. Pour in the sour cream, milk, and the can of cream of chicken soup. Sprinkle in the paprika, garlic powder, onion powder, salt, and pepper. Use a spatula to gently stir everything together until all ingredients are evenly coated and mixed.
Step 5: Assemble the Casserole
Spread the entire mixture into your prepared baking dish, ensuring it is evenly distributed. Sprinkle the top with the remaining 0.5 cup of shredded cheddar cheese and then add the mozzarella cheese for an extra creamy topping.
Step 6: Bake Until Golden
Place the baking dish in the preheated oven and bake uncovered for 25-30 minutes. Keep an eye on it, and look for a bubbling mixture and a beautiful golden-brown cheese top. If you like a crunchier texture up top, you can broil it for an additional 2-3 minutes, but watch closely to prevent burning.
Step 7: Let it Rest
Once it’s out of the oven, allow the casserole to rest for about 5–10 minutes before serving. This helps to set the casserole and allows for easier slicing. For a pop of color, you can garnish your dish with freshly chopped parsley right before serving.

Variations
- Protein: Substitute chicken with turkey, ham, or even a plant-based protein for a vegetarian option.
- Vegetables: Incorporate additional vegetables like bell peppers, carrots, or corn for added flavor and nutrition.
- Spices: Experiment with different herbs such as thyme, basil, or rosemary to elevate the flavor profile.
Cooking Notes
- Roasting the broccoli and potatoes before assembling the casserole can add extra flavor and reduce moisture.

- For a gluten-free option, ensure you use certified gluten-free cream of chicken soup and seasonings.
- Store leftovers in an airtight container in the refrigerator for up to 3 days, or freeze for up to 3 months.
Serving Suggestions
- Serve with a side salad for a complete meal.
- Pair with crusty bread for a hearty companion.
Tips
- Ensure even cooking by cutting chicken and potatoes into similar-sized pieces.
- For extra creaminess, consider adding cream cheese to the mixture.
