Savory Herb Chicken Pot Pie

Why This Savory Herb Chicken Pot Pie Works

During the first step on the stove, the butter coats the onions, carrots, celery, and potatoes so they soften slowly instead of drying out. As they cook, the vegetables lose their crunch and their edges start to break down, so later they blend into the creamy filling instead of staying hard chunks.

After the flour goes in, it soaks up the butter and clings to the vegetables. Once the chicken broth and cream are whisked in and heated, that flour swells and turns the liquid thick. The sauce becomes just thick enough to hold the chicken, peas, and vegetables in place, so the filling stays together and doesn’t run all over the plate.

In the oven, the puff pastry sits on top of that hot, thick filling. The steam from the creamy sauce rises and puffs up the pastry layers, while the egg wash lets the top brown and crisp. Underneath, the chicken and vegetables stay moist because they are sitting in that rich, thick sauce instead of being exposed directly to the oven heat.

Mistakes To Avoid

Letting the roux stay pale and thin before adding the broth keeps it from thickening properly later. The filling then stays runny in the oven, so the pastry floats on top of a loose soup instead of sitting on a creamy base, and the slices won’t hold together when served.

Adding the cream too early, before the broth mixture has thickened and simmered, can cause the sauce to separate. The fat from the cream then sits on top in oily patches, and the filling looks grainy instead of smooth and velvety.

Putting raw or very large chunks of potatoes into the pot and rushing the sauté step often leaves them undercooked. In the finished pie, the sauce may be thick and hot, but the potatoes stay firm or even slightly crunchy in the center.

Skipping the cooling time before serving means the filling hasn’t had a chance to set. The first spoonful then causes the hot, liquid center to spill out, and the pie eats more like a stew with a soggy pastry lid than neat slices.
