Perfect Presentation Platters
I always love sharing my favorite products with you and a mix of both budget-friendly options or pieces that are a bit higher end and make beautiful gifts, like the MacKenzie-Childs items. Here’s what I used!
For the Garlic Bread: I used this Checkered Baguette Dish from Mackenzie-Childs!
Checkered Serving Boards: I used this checkered chopping board, which I use for prep, serving, and decor! For a more affordable version, Temu also has this Checkered Chopping Board that comes in various sizes and is so handy for prep, serving, and decor! I use mine all the time!
Checkered Bowls: I used Mac-Kenzie Child’s Everyday Bowl! You can also use this smaller Ice Cream Dish, which also comes in blue!

Halloween Kitchen Links: You can find my favorite Haunted House Cookie Jar at Pottery Barn! I also love these elegant MacKenzie-Childs Striped Pumpkins set or her Boo Pumpkins Set, which is a bit less expensive. I’m also obsessed with the Cauldron with Witch Boots!
Can I Prep This Chicken Alfredo Casserole in Advance?
Yes! I love to get all of the ingredients in the baking dish in the morning or night before, then pop it in the over to bake before dinnertime. Just be sure to cover with Saran Wrap or aluminum foil and refrigerate if you prep in advance. You can also freeze this dish for up to three months if you prep it in an aluminum baking pan with a plastic cover.

Storing Leftovers
Place any leftover Chicken Alfredo Casserole in a Tupperware container or Ziploc Bag and refrigerate, where it should stay fresh for several days. You can also cover the baking dish with foil or Saran Wrap.

Enjoy!
I hope this decadent Chicken Alfredo Casserole can become a staple in your home! For more delicious (and easy!) pasta recipes, be sure to check out our Crockpot Million Dollar Pasta, flavorful Lemon Garlic Parmesan Pasta, or this creamy Olive Garden Chicken Pasta. Have a wonderful week, friends!
