1 egg, 1 tbsp whole milk
Place carrots, celery, potatoes, and chicken cubes in a medium saucepan and cover with water (~2.5 cups). Bring to a boil for 1 minute and then simmer until vegetables are soft (~10-15 minutes).Pro tip: It will foam a bit for the first few minutes but that is normal.
2 cups carrots, 1 cup celery, 1.5 cup peeled and cubed potatoes, 1 lb chicken breast
Drain the vegetables and chicken, add the peas, and set them aside.
3/4 cup frozen peas
While the vegetables are cooking, heat a large frying pan over medium-low heat.

1/3 cup unsalted butter, 1/3 cup white onion, 4 cloves garlic, 1 tsp sea salt, 1/2 tsp black pepper, 1/4 tsp celery seed, 1 tsp dried parsley

1 sheet puff pastry
Poke holes in the puff pastry with the tines of a fork.
Bake on the middle rack at 400˚F for 15 minutes.
Brush the egg/milk mixture over the top of the puff pastry and bake for an additional 5-15 minutes or until the puff pastry is golden brown. Pro tip: if the pastry is browning too quickly, loosely tent with foil.
Remove from the oven and let stand for 10-15 minutes before cutting/serving.
Notes
Check the directions on the box of your puff pastry to confirm the thawing time. Some brands only recommend 20 minutes and others recommend up to 1 hour.
Celery seed and celery salt are not interchangeable. This recipe calls for celery seed.
Do not skip the step of warming the milk before adding it to the floured onions. This will prevent the sauce from breaking/curdling.
You can also lay the puff pastry over the top of the filling. Just make sure to cut a few slits in it to allow steam to escape. Also, work quickly to cut the slits in as the puff pastry gets challenging to work with when it makes contact with the warm liquid.
