Costco Chicken Bake Copycat Recipe (Easy Chicken Alfredo Style)
This costco chicken alfredo recipe captures the creamy, cheesy filling of the cult-favorite Costco Chicken Bake at home, with no food court line required. It comes together in about 45 minutes and uses ingredients you can grab at any grocery store.
The filling is rich and savory, the pastry bakes up golden and crisp, and the whole thing feeds 4 people without much fuss.
Why I Love This Recipe
The ratio of filling to dough here is generous. Every bite gets that salty, creamy chicken and bacon mixture rather than a mouthful of plain bread.
Caesar dressing does most of the heavy flavoring work, which means fewer ingredients and a sharper, more interesting taste than plain Alfredo sauce alone.
This is the version I keep coming back to when I want something satisfying on a weeknight without a big cleanup.
Recipe Ingredients
- 1 lb (450g) pizza dough – Store-bought works great; let it sit at room temperature for 20 minutes before rolling
- 2 cups cooked chicken breast, shredded – Rotisserie chicken saves time and adds a little extra flavor
- 6 strips bacon, cooked and crumbled – Cook it crispy so it holds up inside the bake
- 1/2 cup Caesar dressing – This is the backbone of the sauce; use a thick, creamy bottled variety
- 1 cup shredded mozzarella cheese – Low-moisture works best here so the filling stays cohesive
- 1/2 cup shredded Parmesan cheese – Adds the salty, nutty edge that Caesar dressing alone can’t
- 1/2 tsp garlic powder – Rounds out the savory flavor in the filling
- 1/4 tsp black pepper – Just enough background heat
- 1 egg, beaten – For the egg wash that gives the crust its golden color
Variations / Substitutions
- Swap the protein – Canned tuna or shredded rotisserie turkey works in place of chicken with virtually the same result.
- Make it spicier – Add 1/4 tsp red pepper flakes to the filling for a low-level heat that builds with each bite.
- Dairy-free cheese – A dairy-free mozzarella shreds and melts reasonably well here, though the filling will be slightly less creamy.
- Lighter dressing – A light Caesar dressing reduces the fat but also thins the sauce, so cut it back to 1/3 cup and add a tablespoon of cream cheese to compensate.
- Different dough – Crescent roll dough gives a flakier, more buttery shell if you prefer that over chewy pizza dough.

How To Make Chicken Alfredo Bake
Step 1: Mix the Filling
In a large bowl, combine the 2 cups shredded chicken, 6 strips of crumbled bacon, 1/2 cup Caesar dressing, 1/2 tsp garlic powder, and 1/4 tsp black pepper. Stir everything together until the chicken is evenly coated. Add 3/4 cup of the mozzarella and all 1/2 cup of the Parmesan, then fold them in gently so the mixture stays thick rather than breaking apart.
The filling should look sticky and cohesive, not wet or soupy. If it seems loose, refrigerate it for 10 minutes before filling the dough.
Step 2: Roll and Fill the Dough
Preheat your oven to 400°F (200°C). On a lightly floured surface, divide the 1 lb pizza dough into 4 equal portions and roll each one into a rectangle roughly 8 inches by 5 inches. Spoon about 1/2 cup of filling down the center of each rectangle, leaving a 1-inch border around the edges.
Fold the long sides of the dough up over the filling and pinch the seam firmly closed. Tuck both ends under and press to seal. A tight seal keeps the cheese from leaking out during baking, so take an extra few seconds here.
Step 3: Brush and Bake the Rolls
Place the filled rolls seam-side down on a parchment-lined baking sheet, spaced about 2 inches apart. Brush the tops and sides with the beaten egg, then scatter the remaining 1/4 cup mozzarella over the top of each roll. Bake at 400°F (200°C) for 22 to 25 minutes, until the crust is deep golden brown and the cheese on top has a few lightly browned spots.
The dough should feel firm and sound slightly hollow if you tap the bottom. If the tops are browning too fast after 15 minutes, lay a loose sheet of foil over them and keep baking.
Step 4: Slice and Serve
Transfer the baked rolls to a cutting board and cut each one diagonally down the center with a sharp knife, revealing the creamy, cheesy interior. Arrange them cut-side up on a platter and finish with a light grating of extra Parmesan over the top.
Recipe Tips
- Choose dough that’s room temperature. Cold dough tears and springs back when you roll it. Give it at least 20 minutes on the counter before you start.
- Cook the bacon until truly crispy. Soft bacon releases moisture inside the bake and makes the filling watery by the time it comes out of the oven.
- Don’t overfill. A heaping 1/2 cup of filling per roll is the right amount. More than that and the seams will split during baking.
- Check the bottom, not just the top. The underside of the rolls should be golden and set. If the tops look done but the bottoms are pale, give them 3 more minutes before pulling.
Bake times by oven type (at 400°F / 200°C):
| Oven Type | Time | Visual Cue |
|---|---|---|
| Conventional | 24 to 25 mins | Deep golden top and bottom |
| Convection | 20 to 22 mins | Golden top, slightly darker edge |
| Toaster oven | 22 to 24 mins | Watch the bottom; rotate at 15 mins |
How To Store
- Refrigerate – Wrap cooled rolls individually in foil or store in an airtight container for up to 3 days.
- Reheating – Reheat in a 350°F (175°C) oven for 10 to 12 minutes directly on the rack. The crust crisps back up this way, whereas a microwave will make it soft and a little gummy.
What To Serve With Chicken Alfredo Bake
A crisp romaine salad with a light vinaigrette cuts through the richness of the filling and keeps the meal from feeling too heavy. Roasted broccoli works well alongside it too, since the slight bitterness of the broccoli balances the creamy, salty filling. If you want something starchy on the side, a simple tomato soup is a natural match because the acidity plays off the Caesar and Parmesan in the bake.
Frequently Asked Questions
Can I assemble the rolls ahead of time?
Yes. Fill and seal the rolls, place them on the baking sheet, and refrigerate uncovered for up to 12 hours. Add the egg wash and cheese topping right before they go into the oven, not before refrigerating.
My seams keep opening during baking. What am I doing wrong?
The dough is probably too wet or too cold at the seam. Press the edges together firmly and use a small amount of water on your fingertip to help seal them before pinching.
Can I freeze these after baking?
Yes. Wrap cooled rolls tightly in foil and freeze for up to 2 months. Reheat from frozen at 375°F (190°C) for 18 to 20 minutes.
How do I know the dough is fully cooked inside?
The internal temperature of the dough should reach at least 190°F (88°C). An instant-read thermometer pushed into the thickest part of the roll, not through the filling, will give you a reliable reading.
