Ingredient Notes

See recipe card below this post for ingredient quantities and full instructions.
- Rotini pasta – You can use another shape if you like, but I think rotini or penne pasta work best for holding all that creamy sauce and bacon! Cook and drain the pasta before starting the recipe.
- Shredded cooked chicken – Use rotisserie chicken or leftovers.
- Alfredo pasta sauce – Creates a rich, creamy base.
- Ranch dressing – Use store-bought or my homemade ranch dressing.
- Chopped cooked bacon – Cook, drain off the bacon grease, and crumble or chop it into small pieces.
- Cheese – A combination of mozzarella cheese and cheddar.
- Parsley – This is optional.
Variations
- Low-Carb Version: Replace pasta with cauliflower.
- Extra Veggies: Mix in broccoli or spinach.
- Different Cheese: Use pepper jack or Colby Jack for a flavor change.
- Buffalo Style: Add buffalo sauce for a spicy kick.
How to Make Chicken Bacon Ranch Casserole

- Combine: Combine cooked pasta, chicken, Alfredo sauce, and ranch dressing in a large bowl.

- Mix: Stir to incorporate everything.

- Transfer: Pour the casserole mixture into the prepared pan and spread it evenly.

- Finish: Top with the shredded mozzarella and cheddar cheeses, followed by the crumbled cooked bacon. Bake the casserole in the preheated oven for 15 to 20 minutes, or until it’s hot and bubbly. Remove the dish from the oven and let it stand for 5 minutes before serving.

Serving Suggestions
This chicken bacon ranch casserole pairs perfectly with:
- Fresh green salad

How to Store and Reheat Leftovers
You can store any leftovers in the baking dish wrapped with foil or plastic wrap, or transfer them to an airtight container. They’ll last in the fridge for 3 to 4 days, and can be reheated in the microwave or a 350ºF oven.
This casserole also freezes well; it can be frozen in an airtight container for up to 2 months. I recommend letting it thaw in the refrigerator, then reheating it in the microwave or oven.

This was perfect for dinner! It’s cheesy, creamy and so delicious.
This was a huge hit with my family! I added less Alfredo and more ranch only because I’m not a huge fan of Alfredo! I also used a triple cheddar blend cheese and Mozzarella!
