I don’t know about you, but I’ve been eating this dish since I was a kid. I’m pretty sure every home cook in America has made this dish, which gained popularity in the 1950s.

And despite it’s French sounding name, it was most likely created in the early 1900s in honor of E. Clark King II, the proprietor of the Brighton Beach Hotel in New York.

All I know is that whoever came up with this recipe is a genius, since chicken a la kind is the epitome of comfort food.

And with the exception of the puff pastry, it all comes together quickly and easily in your slow cooker.

I like to buy the pre-shaped frozen puff pastry shells if I can find them. If not, it works to just cut a sheet of puff pastry into squares, bake them, and spoon your chicken a la king over the top.

You can also serve the chicken mixture over biscuits, and even regular toast. It reminds me of chicken pot pie, or chicken and dumplings. Which is another way of saying it’s delicious.

Not everyone in my family likes mushrooms, but I don’t like to leave them out of this dish. I just make sure to cut them into big slices so they are easy for the picky eaters to find and remove.

Another tip for this recipe, don’t add your peas to the slow cooker until just before serving. That way they’ll stay fresh tasting and green.
