Make Costco Chicken Bake at home with this easy copycat recipe! You'll love the tender chicken, bacon, savory dressing, and cheese wrapped in a crispy homemade crust.
Prep. Preheat the oven to 375°F and line a baking sheet with parchment paper.
Prepare the filling. In a large bowl, combine the cooked chicken, crumbled bacon, shredded mozzarella, Parmesan cheese, and sliced green onions. Add the salt, black pepper, garlic powder, and Italian seasoning. Pour in the Caesar dressing and mix everything until well combined.
Prepare the dough. If the pizza dough is cold, let it sit at room temperature for 15 minutes to soften. Once ready, divide the dough into three equal portions.
Shape the dough. Roll each piece of dough into a rectangle, about 10x6 inches. Keep the dough smooth and even so it's easy to wrap around the filling.
Fill the dough. Take one dough rectangle and spread the prepared filling along one short edge, leaving some space on the sides. Be careful not to overfill. Carefully roll the dough around the filling, starting from the edge of the filling. Pinch the seams together to seal the strudel. Tuck in the ends to secure the filling inside.
Prepare for baking. Place the rolled strudels seam-side down on the baking sheet. Brush the tops with the beaten egg and sprinkle with extra mozzarella and Parmesan cheese.
Bake. Bake the strudels for 20–25 minutes or until golden brown and crispy on top.
Serve. Once baked, let the chicken bake cool for 5 minutes. Sprinkle with chopped parsley before slicing, and enjoy!
