Homemade Costco Chicken Bake

Costco Chicken Bake is filled with diced chicken, smoky bacon crumbles, creamy Caesar dressing, and three types of melty cheeses to create a comfort food delight! You’ll get all of the classic flavors of the food court right in your kitchen with my homemade version. It’s the perfect easy weeknight dinner option!!

Costco Chicken Bake

I think we can all agree that perfectly cooked chicken paired with bacon and cheese, all wrapped in a golden-brown pizza dough is going to taste pretty amazing.

And paired with a tangy Caesar dressing, you really can’t go wrong!!

That’s what you’ll find in my Costco chicken bake. Inspired by one of my favorite frozen foods to pick up when doing my shopping, it’s almost like a Hot Pocket. But better. So, so much better!

It’s super easy to throw together too. 

Using shortcuts like cooked chicken, bacon, and pre-made dressing, and the option of using store-bought pizza dough too, you won’t have to worry about a lot of prep work!

This is just the most recent post in an ever-growing collection of copycat recipes! I’m working on beefing up my Costco copycats in particular… stay tuned for even more coming soon!!

Ingredient Notes and Substitutions

• Pizza Dough – The base of our copycat Costco chicken bake! I like using my homemade 2 ingredient pizza dough to hold in all of the yummy fillings. 
  
  If you don’t have time to make it from scratch, store-bought dough works too!
  
• Chicken – And make sure it’s cooked before getting started! Leftovers are a great option, or grab a rotisserie chicken from the store instead.
  
• Bacon – Also needs to be cooked, and I recommend using thick-cut for extra texture. Baking bacon in the oven is my jam at the moment, or you can use the air fryer. 
  
  Once cooked, crumble it up before adding it to your Costco chicken bake recipe.
  
• Shredded Cheese – I used a combination of mozzarella, provolone, and Parmesan, and you better believe I shred it myself! The pre-shredded bags have anti-caking agents and don’t melt as well.
  
  Cheddar, Monterey Jack, or Gruyère are other options to try!
  
• Creamy Caesar Dressing – Key to getting Costco’s signature flavor! It also adds a touch of tangy, garlicky creaminess that pairs super well with the other ingredients.

Ranch dressing or garlic aioli will give a slightly different flavor but are the best subs.

• Egg – For the egg wash. I swear it gives the best golden and glossy finish!
  
• Green Onion – Adds a pop of color and mild onion flavor without totally overpowering the rest of the bake. Chives would also be good!

Tips and Tricks to Make the Perfect Costco Chicken Bake Recipe

• Use room temperature dough for easier rolling.

Cold dough is tough to stretch (trust me!) and has a tendency to shrink back when rolled. 

Let it sit at room temperature for about 30 minutes before working with it to make rolling it a lot easier — and prevent it from tearing!

And if your room temp dough still doesn’t want to roll out, let it rest for about 5 minutes then try again.

• Chop evenly for the best bite.

When prepping the cooked chicken and bacon, try your best to chop them into similarly sized pieces. 

This ensures that every bite has the perfect mix of chicken, bacon, cheese, and dressing. 

• Don’t overfill the dough!

My chicken bake Costco recipe is definitely loaded with fillings, but it’s not overloaded to the point of major leakage. 

I know it’s tempting to pack in as much yummy goodness as possible, but do your best to stick to the proportions I laid out on the recipe card. 

Too much filling can cause the dough to tear. Leave that 1-inch border I noted as well to make rolling and sealing easier!

• Pinch the seam to seal before baking.

After rolling each Costco chicken bake, pinch the seams and ends tightly to keep the fillings from oozing out in the oven. 

You can even add a little water before pinching to help them stick better.

I also place them seam-side down on the baking sheet to help keep everything together. 

Prep Ahead

• Make the pizza dough
• Cook and chop the chicken and bacon

Kitchen Tools You Will Need

• Large Bowl – This one is my go-to!
• Rolling Pin – In a pinch, an empty wine bottle will work!
• Baking Sheets lined with Parchment Paper – Used for anything from cookies to roasting, a good baking pan will last for years.
• Basting Brush – I like this one over the silicone ones.

Serving Suggestions 

We are a sauce family, so I pull out all of our favorite dipping sauces whenever I make my Costco chicken bake recipe! 

Chad and Munchkin never say no to my Oven Baked Garlic Fries, or sometimes I keep things lighter and pair the bake with a big garden salad and roasted veggies like Brussels or broccoli. 

You can also feel free to switch up — or add to! — the fillings. A few of my favorites to try are sautéed mushrooms, caramelized onions, and roasted red peppers.

Storing and Reheating

If you’d like to get ahead on dinner prep, the filling mixture can be prepped up to 24 hours in advance and stored in the fridge!

Store leftover copycat Costco chicken bake in an airtight container in the refrigerator for up to 3 days, or wrapped in foil in the freezer for up to 2 months. 

Reheat in the oven at 350°F for 10-12 minutes until warmed through. When reheating from frozen I usually add an extra 10-15 minutes and cover with foil for the first 15 to prevent burning.
