Step 1

Preheat oven to 350 degrees. Prepare a 9 x 13 in casserole dish with cooking spray.

Step 2

Spread chicken evenly on the bottom of the casserole dish.

Step 3

Heat the butter in a large skillet on medium-high heat, add the chopped onion. Saute onion for about 3 minutes, until transparent.

Step 4

Sprinkle the flour over the onion and butter, stir well, and allow to thicken.

Step 5

Add the frozen vegetables, broth, soup, cheese, and seasonings. Heat for about 5 minutes, stirring often until thickened.

Step 6

Pour the mixture over the chicken.

Step 7

In a medium bowl, mix the dumpling ingredients together just until moistened.

Step 8

Using a fork, drop dumplings on top of the casserole. Drop by large amounts or small amounts, depending on how large you would like your dumplings to be.

Step 9

Cover with foil and bake for 45 minutes. Remove the foil and bake for an additional 15 minutes.

Step 10

If top of dumplings aren't a nice golden brown, you can broil the casserole (uncovered) for a couple of minutes.
