Place mushrooms in crockpot on low

In a large 12" pan put oil in and melt butter

When melted stir in ranch packet

Pour melted butter over mushrooms in crockpot and cook for 3 hrs on low

After mushrooms are done remove from crockpot and let cool. (Save a few mushrooms and juices for later. No need to turn off crockpot)

Cook spinach in 12" pan while chopping mushrooms finely.

add mushrooms to spinach and finish cooking

Remove mushroom spinach stuffing from heat and chop into smaller chunks

Preheat oven to 300

Use the pocket method on chicken to create the pouch for stuffing. I make the intro slit large enough for a spoon to get through.

Stuff the mushroom spinach stuffing in until you cant get any more in. I stuff with clean fingers to keep the slit small enough not to need to tie or toothpick the intro hole

Heat the pan with oil and a bit of butter until it steams nicely

Salt pepper and garlic powder all sides of chicken and brown all sides (about 1 min each side)

Remove browned chicken from pan and place them into a glass baking pan

Put in oven and cook for about 2 hrs (cook chicken to at least 170 degrees) basting every 15 mins with the juices left over from crockpot mushrooms.

Cut into 1/2" slices and serve with a few leftover crockpot mushrooms
