This chicken pot pie with puff pastry has a rich, creamy filling packed with tender chicken, fresh herbs, parmesan, and cream cheese, all topped with golden, flaky puff pastry squares baked until perfectly crisp. One pan, from scratch, and on the table in under an hour!
Preheat the oven to 425 degrees F. Note: Keep the puff pastry in the refrigerator until we're ready to use it - keeping it cold helps it puff up while baking.
Add chicken breast to a bowl and season with Italian seasoning, kosher salt, and black pepper, ensuring all of the chicken is coated. Add olive oil to a braising pan or dutch oven over medium heat and add the chicken. Cook until golden brown and cooked all the way through, about 5-7 minutes per side. Remove onto a plate to rest. 1 1/2 lbs Chicken Breast2 tsp Italian Seasoning1 tsp Kosher Salt1/2 tsp Black Pepper1 tbsp Olive Oil

Mix together egg and water in a small bowl. Brush the pastry with egg wash, then set the skillet on a parchment-lined baking sheet to catch any overflow. Bake for 25–30 minutes, until the pastry is puffed, crisp, and a deep golden brown. 1 Egg + 1 tbsp water

Notes
Don't skip searing the chicken. It might be tempting to just poach it or use rotisserie chicken every time, but taking those few extra minutes to sear the chicken breast until golden in the pan builds a ton of flavor.
Cook the filling until it's really thick before it goes in the oven. Let the filling simmer and reduce until it coats the back of a spoon, you want it noticeably thick. It will loosen slightly in the oven, and that's exactly the right consistency for scooping.
Keep your puff pastry cold until the last second. Puff pastry puffs best when it goes into a hot oven straight from cold. If it warms up too much while you're working with it, the butter layers start to meld together and you lose that flaky, airy rise.
Use a parchment-lined baking sheet underneath the skillet. This filling is bubbling and rich, and it will overflow a little as it bakes, that's a sign you made it right! Placing the skillet on a lined sheet pan saves you from a smoky oven situation and makes cleanup a breeze.
