Ingredients You’ll Need

For the Casserole

• 2 cups cooked chicken, shredded or diced – Chicken adds lean protein and makes the casserole filling. Rotisserie chicken is a great time-saving option.
• 8 ounces penne pasta – Penne holds the creamy sauce well and stays tender after baking. Rotini or rigatoni also work well.
• 8 slices bacon, cooked and crumbled – Crispy bacon adds smoky flavor and a crunchy bite. Cook it until crisp so it keeps its texture in the casserole.
• 1 can (10.5 ounces) cream of chicken soup – Cream of chicken soup creates the creamy base that brings everything together.
• ½ cup sour cream – Sour cream adds richness and a slight tang that balances the cheese.
• ½ cup milk – Milk helps thin the sauce so it coats every piece of pasta.
• 2 cups shredded cheddar cheese, divided – Cheddar cheese melts beautifully and creates a bubbly, golden topping. Reserve some for the top.
• 1 small onion, diced – Onion adds sweetness and extra flavor throughout the casserole.
• 2 garlic cloves, minced – Fresh garlic gives the casserole a savory boost.
• 1 teaspoon ranch seasoning – Ranch seasoning pairs perfectly with the chicken, bacon, and cheese for extra flavor.
• ½ teaspoon smoked paprika – Smoked paprika enhances the bacon with a subtle smoky flavor.
• ½ teaspoon salt – Salt brings out the flavors of the other ingredients. Adjust to taste.
• ¼ teaspoon black pepper – Black pepper adds gentle warmth.
• 2 tablespoons chopped green onions – Green onions add freshness and a pop of color before serving.

Common Mistakes to Avoid

Overcooking the pasta

Cook the pasta just until al dente since it will continue cooking in the oven. Overcooked pasta can become too soft after baking.

Using soft bacon

Cook the bacon until it’s nice and crispy before adding it to the casserole. Crispy bacon holds its texture much better.

Skipping the resting time

Let the casserole sit for 5 to 10 minutes before serving. This gives the sauce time to thicken and makes serving much easier.

Adding too much salt

Bacon, cheese, ranch seasoning, and canned soup already contain salt, so taste the sauce before adding extra seasoning.

Using pre-shredded cheese only

Freshly shredded cheddar cheese melts more smoothly and gives the casserole a creamier texture.
