Step 1

Break bread up into small piece and leave out overnight to dry. Dice the onions and the celery. Chop the parsley. Slice the mushrooms if needed. Store the onions and celery together but the mushrooms and parsley separately in the fridge.

Step 2

Over medium heat, add 2 tablespoons of the butter and let melt. Once melted, add the sliced mushrooms, spread out into a single layer, and let cook to brown for 2-3 minutes. Stir to brown all sides and cook for another 5 minutes until reduced by half. Then add the onions and celery and cook until soft and translucent, about 8 minutes. Finally, add in the rest of the butter and keep the heat on just until it melts.

Step 3

In a large bowl. add the dried bread, cooked onions and celery, mushrooms, poultry seasoning, salt, pepper. Mix to combine. Drizzle 1/2 cup of the broth over the bread to moisten and mix with your hands.

Step 4

Beat the egg with 1/4 cup of broth (cooled). Add it to the bread along with the parsley and mix with hands to distribute evenly.

Step 5

Test the stuffing to see if it is moist and clumps together in your hands. If the bread still looks dry, drizzle in another 1/4 cup of broth as needed and mix with hands until fully moistened. but not too wet.

Step 6

Preheat oven to 400 degrees F.

Step 7

Take the chicken breast and start to slowly slice into the size, horizontally. Is you start to cut into the side, pull up on the top half to help the knife cut straight through. Continue to slice through the center horizontally until almost to the other side, but do not slice all the way through as you will open the chicken up flat.

Step 8

Place the chicken between 2 pieces of plastic wrap and pound it out gently to be an even flat piece about ¼ inch thick. Season both sides of the chicken breasts with salt and pepper.

Step 9

Place 2 tablespoons of the stuffing in the center of each chicken breast. Roll the chicken around the stuffing and secure the flap with toothpicks.

Step 10

In a preheated (high heat) large saute pan, drizzle Olive Oil (to coat) and sear the chicken on all sides. Then put into the preheated oven to cook for 15-20 minutes, until the internal temperature reaches 165 degrees F.

Step 11

Put any extra in a casserole dish to cook in the oven covered. Cook for 30-45 minutes at 350F degrees until internal temp reaches 165F. For the last 10 minutes. remove the cover so that the top gets browned and crisp.
