• Garlic: Minced garlic (because everything tastes better with garlic).
• Flour: All-purpose flour to thicken the sauce.
• Chicken Broth: Adds flavor and depth to the creamy sauce.
• Milk: Whole milk for creaminess (or use half-and-half for extra indulgence).
• Cheese: Shredded cheddar and mozzarella for melty goodness.
• Sour Cream: Adds tang and creaminess to the sauce.
• Seasonings: Salt, pepper, and paprika for a balanced flavor profile.
• Breadcrumbs: For a crunchy topping.
• Parsley: Fresh parsley for garnish (optional, but adds a pop of color).

If you’re looking for substitutions, you can use rotisserie chicken for convenience, almond milk for a dairy-free option, or gluten-free breadcrumbs for dietary needs. This recipe is incredibly adaptable!

Equipment Needed

To make this chicken casserole, you’ll need the following kitchen tools:

• Large Skillet: For sautéing the onions and garlic.
• Whisk: To ensure a smooth, lump-free sauce.
• Baking Dish: A 9×13-inch casserole dish works perfectly.
• Mixing Bowl: For combining the sauce and chicken.
• Knife and Cutting Board: For prepping the vegetables and chicken.
• Oven: Preheated to 375°F (190°C).

If you don’t have a whisk, a fork can work in a pinch. And if you’re short on oven-safe dishes, you can use disposable foil pans for easy cleanup after your party.

Preparation Method

1. Cook the Chicken: Boil or bake the chicken breasts until fully cooked. Shred them using two forks and set aside.
2. Preheat the Oven: Set your oven to 375°F (190°C).
3. Sauté the Vegetables: In a large skillet, melt butter over medium heat. Add diced onions and garlic, cooking until softened and fragrant, about 3-4 minutes.
4. Make the Sauce: Sprinkle the flour over the onions and garlic, stirring to combine. Gradually whisk in chicken broth and milk, cooking until the mixture thickens, about 5 minutes. Stir in shredded cheddar, mozzarella, and sour cream until smooth. Add salt, pepper, and paprika to taste.
5. Combine: In a large mixing bowl, combine the shredded chicken with the sauce. Mix until the chicken is evenly coated.
6. Assemble: Pour the chicken mixture into a greased 9×13-inch baking dish. Smooth out the top with a spatula.
7. Add the Topping: Sprinkle breadcrumbs evenly over the casserole. Add extra shredded cheese if desired.
8. Bake: Place the casserole in the oven and bake for 25-30 minutes, or until the topping is golden brown and the sauce is bubbling.
9. Garnish: Remove from the oven and let it cool for 5 minutes. Garnish with fresh parsley before serving.

Pro tip: If your sauce seems too thick, add a splash of milk to loosen it up. And don’t forget to taste-test the seasoning before assembling everything!

Cooking Tips & Techniques

• Don’t Overcook the Chicken: Keep an eye on the chicken while boiling or baking. Overcooking can make it dry.
• Use Fresh Cheese: Grating your own cheese ensures better melting and flavor compared to pre-shredded varieties.
• Layer Evenly: Smooth out the chicken mixture in the casserole dish to ensure even baking.
• Troubleshooting Sauce: If your sauce is lumpy, whisk vigorously or strain it through a fine mesh sieve.
• Make Ahead: Assemble the casserole a day ahead, cover with foil, and refrigerate. Bake it fresh before serving.

Variations & Adaptations

• Low-Carb Option: Swap the breadcrumbs for crushed pork rinds or almond flour.
• Vegetarian Version: Substitute chicken with sautéed mushrooms and zucchini for a hearty veggie casserole.
• Spicy Twist: Add diced jalapeños or a pinch of cayenne pepper to the sauce for heat.
• Seasonal Adaptation: Mix in fresh spinach or roasted butternut squash for a seasonal flair.

I once swapped the chicken with turkey after Thanksgiving, and it turned out just as delicious. Get creative and make it your own!

Serving & Storage Suggestions

Here’s how to serve and store your irresistible chicken casserole:
