Step 1: Prepare the Chicken
• Layer Ingredients: Place the chicken breasts in the bottom of the crockpot. If using, add the sliced mushrooms or chopped onions on top of the chicken.

Step 2: Mix the Gravy
• Combine Soup and Seasonings: In a bowl, mix together the cream of chicken soup, ranch dressing mix, chicken broth, garlic powder, and black pepper until well combined.
• Pour Over Chicken: Pour the gravy mixture over the chicken in the crockpot.

Step 3: Cook
• Cover and Cook: Cover the crockpot and cook on low for 6-8 hours or on high for 3-4 hours, until the chicken is cooked through and tender.

Step 4: Shred the Chicken
• Shred Chicken: Once cooked, remove the chicken from the crockpot and shred it using two forks. Return the shredded chicken to the pot and stir to combine with the gravy.

Step 5: Serve
• Enjoy: Serve the chicken and gravy over rice, mashed potatoes, or egg noodles. Garnish with fresh parsley if desired.
