Ingredients You’ll Need

For the Casserole

• 2 cups cooked chicken, shredded or diced – Chicken makes the casserole hearty and filling. Rotisserie chicken or leftover grilled chicken both work perfectly.
• 8 ounces penne or rotini pasta – Short pasta holds the creamy ranch sauce well and stays tender after baking.
• 1 can (10.5 ounces) cream of chicken soup – Cream of chicken soup creates the rich, creamy base for the casserole.
• 1 cup sour cream – Sour cream adds extra creaminess and a slight tang that pairs perfectly with ranch seasoning.
• ½ cup milk – Milk thins the sauce just enough to coat every piece of pasta.
• 1 packet ranch seasoning mix – Ranch seasoning gives the casserole its signature savory flavor with almost no extra work.
• 2 cups shredded cheddar cheese, divided – Cheddar cheese melts beautifully and creates a bubbly, golden topping.
• ½ cup cooked bacon, crumbled – Crispy bacon adds smoky flavor and a little crunch to every bite.
• 2 garlic cloves, minced – Fresh garlic adds extra savory flavor that complements the ranch seasoning.
• ½ teaspoon onion powder – Onion powder deepens the flavor without adding extra texture.
• ¼ teaspoon black pepper – Black pepper balances the richness of the creamy sauce.
• 2 tablespoons chopped fresh parsley – Fresh parsley adds color and a fresh finish before serving.

Cook the pasta according to the package directions until al dente.

Drain well and set aside.

In a large mixing bowl, combine the cream of chicken soup, sour cream, milk, ranch seasoning, garlic, onion powder, black pepper, and 1½ cups shredded cheddar cheese.

Mix until smooth.

Add the cooked pasta, chicken, and crumbled bacon to the bowl.

Stir until everything is evenly coated with the creamy ranch sauce.

Freeze the baked casserole in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before reheating.

Common Mistakes to Avoid

Overcooking the pasta

Cook the pasta just until al dente since it will continue cooking in the oven. This keeps it from becoming mushy.

Adding too much ranch seasoning

Ranch seasoning is concentrated, so stick to one packet unless you prefer a much stronger flavor.

Using soft bacon

Cook the bacon until it’s crispy before adding it to the casserole. It holds its texture much better during baking.

Skipping the resting time

Let the casserole rest for 5 to 10 minutes before serving. This allows the sauce to thicken and makes serving much easier.

Using pre-shredded cheese only

Freshly shredded cheddar cheese melts more smoothly and creates a creamier casserole than pre-shredded cheese.
