This Southern-style casserole blends creamy textures with savory flavors, and it's a great way to use leftover chicken or stretch a rotisserie bird into a second meal.

🛒 Ingredients

Here's what you'll need for a 9x13-inch casserole (serves 6–8):

• 2 cups elbow macaroni (uncooked)

• 2 tablespoons butter

• 1 small onion, finely chopped

• 2 cloves garlic, minced

• 2 tablespoons all-purpose flour

• 2 cups milk (whole or 2%)

• 1 cup chicken broth

• 2 cups cooked chicken, shredded or diced

• 2½ cups shredded sharp cheddar cheese (divided)

• ½ teaspoon salt

• ½ teaspoon black pepper

• ½ teaspoon paprika (optional)

• ½ cup breadcrumbs or crushed Ritz crackers (for topping)

• 1 tablespoon olive oil or melted butter (for topping)

🍳 Step-by-Step Instructions

1. Cook the Macaroni

Bring a large pot of salted water to a boil. Add the macaroni and cook until just al dente-about 1–2 minutes less than the package instructions. Drain and set aside.

2. Make the Cheese Sauce

In a large saucepan, melt the butter over medium heat. Add the chopped onion and sauté until soft and translucent, about 4–5 minutes. Stir in the garlic and cook for another 30 seconds.

Sprinkle in the flour and whisk constantly for 1–2 minutes to form a roux. Slowly pour in the milk and chicken broth, whisking to avoid lumps. Bring the mixture to a gentle simmer and cook until thickened, about 5–7 minutes.

Reduce the heat to low and stir in 2 cups of the shredded cheddar cheese. Add salt, pepper, and paprika if using. Stir until the cheese is melted and the sauce is smooth.

3. Combine Chicken and Pasta

Add the cooked macaroni and shredded chicken to the cheese sauce. Stir until everything is evenly coated. Taste and adjust seasoning if needed.

4. Assemble the Casserole

Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish. Pour the macaroni mixture into the dish and spread it evenly.

Sprinkle the remaining ½ cup of cheddar cheese over the top. In a small bowl, mix the breadcrumbs or crushed crackers with olive oil or melted butter, then sprinkle over the cheese layer for a crispy topping.

5. Bake Until Golden

Bake uncovered for 25–30 minutes, or until the casserole is bubbling and the top is golden brown. Let it rest for 5–10 minutes before serving to allow the flavors to settle.

Serving Suggestions

Pair this casserole with a crisp green salad, steamed broccoli, or Southern-style green beans for a balanced meal. It also reheats beautifully, making it ideal for leftovers or meal prep.

Variations and Tips

• Add veggies: Stir in cooked broccoli, peas, or sautéed mushrooms for extra nutrition.

• Spice it up: Add a pinch of cayenne or a dash of hot sauce to the cheese sauce for a kick.

• Make it ahead: Assemble the casserole up to a day in advance and refrigerate. Bake when ready to serve, adding 10 extra minutes to the cook time.
