Ingredients You’ll Need

These ingredients come together beautifully to recreate that signature Costco flavor. Each component brings its own magic—from the smoky bacon and tender chicken to the melty cheeses and Italian seasoning that give it that irresistible aroma. When shopping, fresh chicken and high-quality pizza dough really make a difference.

Bacon: Use thick-cut for more texture and smoky flavor that stands out.
Chicken breast: Opt for fresh, boneless breasts to ensure even cooking and juicy meat.
Parmesan cheese: Freshly grated Parmesan adds a sharp, nutty kick—don’t skip it for pre-grated stuff.
Mozzarella cheese: Fresh shredded mozzarella melts best and gives that classic gooey stretch.
Egg wash: A simple beaten egg with water or milk gives the crust a beautiful golden color and shine.
Extra-virgin olive oil: Dividing it for cooking and assembling helps lock in flavor and crisp the crust.
Italian seasoning: Adds an herby depth and brings all the components together.
Kosher salt and freshly ground black pepper: Season to taste—you want layers of flavor without overpowering.
Pizza dough: Use store-bought for convenience or homemade if you’re feeling adventurous.
Caesar dressing: Gives that rich, tangy base that contrasts perfectly with the cheesy filling.
Green onions: Thinly sliced for a fresh, crispy bite.
Chopped parsley: For a pop of color and a subtle freshness as garnish.

Variations

I love how versatile this Costco Chicken Bake Recipe is. You can totally customize it to suit your taste or dietary needs. I sometimes switch up ingredients based on what I have handy or how indulgent I’m feeling that day—go ahead and experiment!

Make it spicy: I add a pinch of red pepper flakes or swap the Caesar for a chipotle ranch to give it a nice kick.
Gluten-free: Use gluten-free pizza dough if you’re sensitive, and the bake works just as well without losing flavor.
Vegetarian twist: Swap chicken and bacon for mushrooms and roasted peppers for a smoky, satisfying bite.
Cheese overload: Add some shredded cheddar or pepper jack if mozzarella and Parmesan aren’t enough to satisfy your cheese cravings.

How to Make Costco Chicken Bake Recipe

Step 1: Cook your bacon and chicken perfectly

Start by cooking the bacon in a skillet over medium heat until it’s crisp but not burnt—about 8 minutes. This step is key for that smoky flavor foundation. Remove the bacon, let it drain on paper towels, then chop it up into bite-size pieces. In the same skillet, add a bit of olive oil if needed and cook the chicken breasts, seasoning them with salt, pepper, and Italian seasoning. Cook until golden and cooked through, about 5-7 minutes per side. Once done, dice the chicken into small chunks—bite-sized pieces blend best with cheese and dough.

Step 2: Mix the filling with cheese, dressing, and herbs

In a large bowl, toss together the chopped bacon, diced chicken, shredded mozzarella, Parmesan, green onions, and Caesar dressing. This is the heart of your Costco Chicken Bake Recipe—rich, cheesy, and full of flavor. Give it a gentle stir to combine everything without squashing the chicken too much. You want every bite to have a balance of creamy cheese and savory protein.

Step 3: Prepare and fill the pizza dough

Roll out your pizza dough on a lightly floured surface into a rectangle about 12×15 inches. Brush the edges with olive oil to make sealing easier. Spoon the filling evenly over the dough, leaving about an inch border all around. Now comes the fun part—fold and roll! Fold the dough over the filling like a jelly roll, then pinch and seal the edges tightly to trap all the savory goodness inside. You don’t want any leaks during baking.

Step 4: Egg wash and seasoning for golden perfection

Brush the entire surface of your chicken bake with the egg wash—that mix of beaten egg and water or milk. This step is what gives that irresistible golden crust just like at Costco. Sprinkle a little Italian seasoning and extra Parmesan on top for that final professional touch. Don’t skip this – it really seals the deal.

Step 5: Bake until bubbly and golden

Place your filled dough on a parchment-lined baking sheet and pop it in a preheated oven at 375°F (190°C) for about 25-30 minutes. Keep an eye on it – you want the crust to be golden brown and the cheese inside to melt and bubble nicely. For extra crispness, you can broil for the last 2 minutes, but watch carefully to avoid burning.

Garnishes

I like sprinkling a bit more fresh parsley and green onions right after baking; it adds freshness and color that contrast nicely with the rich filling. Sometimes, a drizzle of extra Caesar dressing on the side works beautifully if you like that creamy tang.

Side Dishes

This bake pairs really well with a simple green salad or some roasted veggies to balance the richness. I often throw together a quick arugula salad with lemon vinaigrette, or serve with steamed broccoli and garlic bread for a crowd-pleasing combo.

Creative Ways to Present

For gatherings, I slice the bake into individual portions and arrange them on a platter with fresh herb sprigs. Adding colorful roasted peppers or a small dipping bowl of Caesar dressing makes it feel extra special—a casual yet polished presentation your guests will love.

Make Ahead and Storage

Storing Leftovers

I store leftovers in an airtight container in the fridge, and they keep well for up to 3 days. The pastry might soften a bit, but reheating crisps it right back up.

Freezing

Freezing works great if you want to prep in advance. Just wrap the unbaked chicken bake tightly in plastic wrap and foil before freezing. When ready, thaw overnight in the fridge then bake as directed. This is a huge time saver for busy nights!

Reheating

To reheat, I usually pop slices in a 350°F (175°C) oven for 10-15 minutes. This revives the crispy crust and melts the cheese back to gooey perfection—microwaving tends to make it soggy, so avoid that if you can.

FAQs

Can I make the Costco Chicken Bake Recipe without bacon?

Absolutely! If you prefer to skip the bacon, the recipe still works great with just chicken and cheese. You can also add extra herbs or a smoky paprika to mimic some of that bacon flavor without using meat.
Is this recipe freezer-friendly?

Yes, this Costco Chicken Bake Recipe freezes well before baking. Just wrap it tightly and freeze. Thaw before baking for best results, and you’ll have a delicious ready-made meal whenever you want.
Can I use pre-cooked rotisserie chicken instead of raw chicken breast?

You sure can! Using pre-cooked rotisserie chicken is a fantastic shortcut that saves time. Just shred the chicken and mix it into the filling, reducing cooking time overall.
What’s the best type of pizza dough for this recipe?

Store-bought refrigerated or frozen pizza dough works perfectly, but if you enjoy making dough from scratch, that’s even better. The goal is a dough that’s sturdy enough to hold the filling yet light and crispy once baked.
How do I prevent the chicken bake from leaking while baking?

Sealing the edges well is crucial. Make sure to press the dough firmly along the seams and a gentle egg wash helps keep it sealed while baking. Also, not overfilling the bake reduces the chances of leaks.
