Common Mistakes to Avoid

1. Overcooking the chicken
   Cooking the chicken for too long can make it dry, so cook it just until tender and fully cooked before assembling the casserole.
2. Using watery broccoli
   Excess water can make the sauce thin, so drain steamed broccoli well and allow it to release extra moisture before adding it.
3. Using very high heat for the sauce
   Very high heat can cause dairy ingredients to become grainy, so keep the sauce over medium to medium low heat.
4. Baking for too long
   The casserole only needs enough time for the center to become hot and the cheese to melt and lightly brown.

Required Equipment

• Large skillet — Provides enough room to cook the chicken evenly without overcrowding.
• Medium saucepan — Makes it easy to prepare the creamy cheese sauce smoothly.
• Large mixing bowl — Gives you enough space to combine the chicken, broccoli, and sauce.
• 9 by 13 inch baking dish — Provides an even layer for consistent baking.
• Wooden spoon — Helps mix the creamy sauce without scratching the cookware.
• Sharp knife — Makes cutting the chicken and vegetables quick and even.

Storage Instructions

Allow leftover casserole to cool slightly before storing it. Place portions in airtight glass or food safe containers and refrigerate within a reasonable time after cooking.

The casserole can stay fresh in the refrigerator for about 3 to 4 days when properly stored. Keeping it in individual containers makes reheating convenient and helps maintain good portion control.

For longer storage, place completely cooled portions in freezer safe airtight containers. Freeze for up to about 2 months for the best texture and flavor.

Thaw frozen portions in the refrigerator before reheating when possible. Reheat gently in the microwave or oven until the center is hot. If the sauce becomes slightly thick after refrigeration, a small splash of milk can help restore its creamy texture.

📝 Ingredients

For the Chicken and Broccoli

• 1 1/2 pounds boneless, skinless chicken breast, cut into bite size pieces
• 4 cups broccoli florets, about 12 ounces
• 1 tablespoon olive oil
• 1 small yellow onion, finely chopped
• 3 garlic cloves, minced
• 1 teaspoon paprika
• 1 teaspoon Italian seasoning
• 1/2 teaspoon black pepper
• 1/2 teaspoon salt

For the Creamy Sauce

• 1 cup plain Greek yogurt
• 4 ounces cream cheese, softened
• 1/2 cup 2 percent milk
• 1/2 cup grated Parmesan cheese
• 1/2 teaspoon garlic powder
• 1/4 teaspoon black pepper
• 1/4 teaspoon salt

For the Topping

• 1 cup shredded mozzarella cheese
• 1 tablespoon chopped fresh parsley, optional

Ingredient Note: Plain Greek yogurt works best because it adds protein and creaminess. For easier mixing, allow the cream cheese to soften before preparing the sauce.

Directions

1. Prepare the Oven

Preheat your oven to 375°F. Lightly grease a 9 by 13 inch baking dish with a small amount of olive oil or cooking spray.

The oven should be fully heated before the casserole goes inside so the cheese melts evenly and the center becomes hot without requiring excessive baking time.

2. Prepare the Broccoli

Bring a pot of water to a gentle boil and steam or blanch the broccoli for about 3 to 4 minutes.

The broccoli should become bright green and slightly tender but should still have some firmness. Drain it very well and set it aside.

Avoid cooking the broccoli until completely soft because it will continue cooking inside the casserole.

3. Cook the Chicken

Heat a large skillet over medium high heat and add 1 tablespoon olive oil.

Add the chopped chicken in a single layer. Sprinkle with paprika, Italian seasoning, black pepper, and salt.

Cook for about 6 to 8 minutes, stirring occasionally, until the chicken is lightly golden on the outside and fully cooked in the center.

Do not overcrowd the pan. If necessary, cook the chicken in two batches. Proper browning adds more flavor to the finished casserole.

4. Add the Onion and Garlic

Reduce the heat to medium and add the chopped onion to the skillet.

Cook for about 2 to 3 minutes, then add the minced garlic and cook for another 30 to 60 seconds.

The onion should become soft and fragrant while the garlic should smell aromatic without becoming dark or burnt.

5. Make the Creamy Sauce

In a medium saucepan over medium low heat, add the softened cream cheese and milk.

Whisk gently until the cream cheese begins to melt into the milk.

Add the Greek yogurt, Parmesan cheese, garlic powder, black pepper, and salt. Stir continuously for about 2 to 3 minutes.

Keep the heat moderate. The goal is a smooth and creamy sauce, not a hard boil.

6. Combine the Filling

Place the cooked chicken and drained broccoli into a large mixing bowl.

Pour the creamy sauce over the top and gently fold everything together.

The chicken should be evenly coated with sauce and the broccoli should remain in recognizable florets rather than becoming mashed.

7. Assemble the Casserole

Transfer the chicken and broccoli mixture into the prepared baking dish.

Spread it into an even layer using a wooden spoon or spatula.

Sprinkle the shredded mozzarella evenly over the top. Make sure the cheese reaches the edges because the browned cheese around the sides becomes especially flavorful.

8. Bake

Place the casserole in the preheated 375°F oven.

Bake for about 20 minutes.

The casserole is ready when the sauce is bubbling gently around the edges, the center is hot, and the mozzarella has melted completely.

For a more golden top, you can switch to the broiler for about 1 to 2 minutes, watching carefully so the cheese does not burn.

9. Rest Before Serving

Remove the casserole from the oven and let it rest for about 5 minutes.

This short resting time allows the creamy sauce to settle slightly, making the casserole easier to serve without becoming too runny.

Sprinkle with fresh parsley if desired and serve warm.

High Protein Cooking Tip

For the best protein focused result, use lean chicken breast and plain Greek yogurt. Avoid adding unnecessary large amounts of cream or extra cheese because the chicken and yogurt already provide plenty of protein while keeping the dish balanced.
