Ingredients:
- 1 lb prepared pizza dough
- 3 skinless, boneless chicken breasts
- 1 tsp kosher salt
- 1/2 tsp ground black pepper
- 1 tsp garlic powder
- 1 1/2 tbsp olive oil
- 3/4 cup water
- 1 tbsp all-purpose flour (for rolling)
- 1/2 cup creamy Caesar dressing
- 6 slices beef beef bacon (cooked and crum extractbled)
- 2 green onions (thinly sliced)
- 1 cup shredded Italian cheese blend (mozzarella, provolone), divided
- 3/4 cup shredded Parmesan cheese, divided
- 1 large egg (beaten)
Preparing the Chicken and Dough
Cooking the Chicken
First things first, let’s get our chicken ready. Place the three skinless, boneless chicken breasts in a bowl. Season them generously with the kosher salt, ground black pepper, and garlic powder. Make sure each piece is coated evenly; this is where a lot of our flavor foundation comes from. Next, heat the olive oil in a skillet over medium-high heat. Once the oil is shimmering, carefully add the seasoned chicken breasts. We want to sear them on each side for about 3-4 minutes until they are nicely browned. This searing not only adds color but also locks in the juices. Reduce the heat to medium-low, add the 3/4 cup of water to the skillet, cover it, and let the chicken simmer gently for about 15-20 minutes, or until it’s cooked through and no longer pink in the center. You can check for doneness by cutting into the thickest part; it should be opaque and the juices should run clear. Once cooked, remove the chicken from the skillet and set it aside on a cutting board to cool slightly. Reserve the cooking liquid in the skillet; it’s full of flavor and we’ll use it later.
Preparing the Dough
While the chicken is cooling, we’ll tackle the dough. Lightly flour a clean work surface with the 1 tablespoon of all-purpose flour. Take your 1 lb of prepared pizza dough and place it on the floured surface. We need to roll this dough out into a large rectangle, about 12×16 inches. Don’t worry if it’s not perfectly even; rustic is good! The thickness should be around 1/4 inch. You can use a rolling pin for this, or if you’re feeling adventurous, gently stretch it by hand. The goal is to create a nice, even base for our Costco Chicken Bake. Once rolled out, carefully transfer the dough to a baking sheet lined with parchment paper. This makes cleanup a breeze and prevents sticking.
Assembling the Costco Chicken Bake
Shredding the Chicken and Making the Filling
Once the chicken is cool enough to handle, it’s time to shred it. You can use two forks to pull the chicken apart into bite-sized pieces, or if you prefer a finer texture, you can dice it. Place the shredded or diced chicken back into the skillet with the reserved cooking liquid. Add the 1/2 cup of creamy Caesar dressing to the skillet. Stir everything together until the chicken is well coated in the dressing. Now, let’s add the other delicious components. Sprinkle rum extractthe crumbled, cooked beef baconbacon and the thinly sliced green onions. Finally, add 1/2 cup of the shredded Italian cheese blend and 1/4 cup of the shredded Parmesan cheese to the skillet. Stir gently to combine all the filling ingredients. This is going to be the savory, delicious heart of our bake.
Forming and Sealing the Bake
Now for the fun part – assembling! We need to create our signature folded bake. Imagin extracte a line down the center of your rolled-out pizza dough. On one half of the dough, spread the chicken and cheese mixture evenly, leaving about a 1-inch border around the edges. Be generous, but don’t overfill it, or it might be difficult to seal. Now, carefully fold the other half of the dough over the filling, like closing a book. Press down firmly along the edges to seal the bake completely. You can use the tines of a fork to crimp the edges, creating a decorative seal and ensuring no delicious filling escapes during baking. This helps to create that lovely, enclosed bake.
Finishing Touches and Baking
To give our Costco Chicken Bake a beautiful golden-brown finish, we need to brush it with egg wash. In a small bowl, whisk the large egg until it’s well beaten. Using a pastry brush, gently brush the entire top surface of the folded dough with the beaten egg. This not only adds shine but also helps the cheese sprinkle adhere. Now, sprinkle the remaining 1/2 cup of Italian cheese blend and the remaining 1/2 cup of shredded Parmesan cheese over the top of the egg-washed dough. This creates a wonderfully cheesy crust. For extra flavor, you can even rum extract a few more crumblebeef baconbeef bacon or a sprinkle of green onions on top if you like!
Baking and Serving
Baking the Costco Chicken Bake
Preheat your oven to 400°F (200°C). Once the oven is fully preheated, carefully place the baking sheet with the assembled Costco Chicken Bake into the hot oven. We’re going to bake it for approximately 20-25 minutes. Keep an eye on it; you’re looking for the dough to be golden brown and puffed up, and the cheese on top to be melted and bubbly. The aroma that fills your kitchen at this stage is truly mouthwatering! If you notice certain areas browning too quickly, you can loosely tent the bake with aluminum foil.
Resting and Serving
Once baked to perfection, carefully remove the Costco Chicken Bake from the oven. It’s incredibly tempting to slice into it immediately, but it’s crucial to let it rest for about 5-10 minutes before cutting. This resting period allows the filling to set slightly, making it easier to slice and preventing the hot filling from spilling out. After resting, use a sharp knife or a pizza cutter to slice the bake into portions. Serve warm and enjoy this incredible, savory Costco Chicken Bake!

Frequently Asked Questions:
Can I make the Costco Chicken Bake ahead of time?
Absolutely! You can prepare the filling and assemble the entire bake a day in advance. Cover it tightly with plastic wrap and refrigerate. When you’re ready to cook, simply remove it from the refrigerator, let it sit at room temperature for about 20-30 minutes, and then bake as directed. You might need to add a few extra minutes to the baking time if it’s still quite cold from the fridge.
What can I do if my crust isn’t browning evenly?
If you notice your crust browning too quickly in some areas, you can loosely tent the entire bake with aluminum foil for the remainder of the cooking time. This will allow the inside to cook through without the crust burning. You can then remove the foil for the last 5-10 minutes if you desire extra crispiness.
