Ingredients for Cheesy Chicken Bacon Ranch Casserole

• 12 ounces penne or rotini pasta
• 8 slices bacon
• 3 cups cooked shredded chicken (about 1 rotisserie chicken)
• 1 can (10.5 oz) condensed cream of chicken soup
• 3/4 cup milk
• 1/2 cup ranch dressing
• 1 packet (1 oz) ranch seasoning mix
• 2 cups shredded cheese (1 cup cheddar and 1 cup mozzarella), divided
• 1 cup frozen peas or broccoli florets (optional)
• Chopped green onions, for serving

Ingredient Notes

• Pasta: Cook it 2 minutes less than the package says. It finishes cooking in the oven.
• Bacon: Thick-cut bacon stays crisp in the casserole. Cook it fully and drain on paper towels.
• Ranch: The dressing and the dry seasoning packet work together for a bold ranch flavor.

How to Make Chicken Bacon Ranch Casserole

Step 1: Cook the pasta

Heat the oven to 350 degrees F and grease a 9×13 inch baking dish. Boil the pasta for 2 minutes less than the package directs, then drain.

Step 2: Cook the bacon

Cook the bacon in a skillet until crisp, drain on paper towels, and crumble.

Step 3: Make the sauce

In a large bowl, whisk the soup, milk, ranch dressing, and ranch seasoning until smooth.

Step 4: Combine

Fold in the pasta, chicken, half the bacon, the peas or broccoli if using, and 1 cup of the cheese.

Step 5: Top and bake

Spread into the dish and top with the remaining cheese and bacon. Cover with foil and bake for 20 minutes, then uncover and bake 10 minutes more, until bubbling and golden and hot in the center (165°F / 74°C).

Step 6: Rest and serve

Rest for 5 minutes, then top with green onions.

Why This Chicken Bacon Ranch Casserole Recipe Works

Undercooking the pasta slightly means it absorbs some of the sauce in the oven, so the casserole turns creamy instead of dry. Mixing ranch dressing with the dry seasoning gives the sauce both tang and savory depth. And keeping half of the bacon for the top keeps it crisp instead of soggy.

My Best Tips for the Chicken Bacon Ranch Pasta Bake

• Undercook the pasta or it will turn mushy.
• Keep half the bacon for topping.
• Cover for the first 20 minutes so the pasta stays moist.
• Do not overbake. Pull it when it bubbles.
• Add a splash of milk when reheating to loosen the sauce.
