Step 1: Place the chicken breasts in the bottom of the crockpot.

Step 2: In a medium bowl, mix together the cream of chicken soup, cream of mushroom soup, chicken broth, garlic powder, onion powder, salt, and pepper. Pour the mixture over the chicken in the crockpot.

Step 3: Cover and cook on low for 4 hours or until the chicken is cooked through and tender.

Step 4: Once the chicken is done, shred it using two forks and stir it into the sauce.

Step 5: Add the cream cheese, cheddar cheese, mozzarella cheese, and Parmesan cheese to the crockpot. Stir until the cheese is melted and the sauce is creamy.

Step 6: In a separate pot, cook the spaghetti according to the package instructions. Drain and add it to the crockpot, mixing well to combine with the cheesy sauce.

Step 7: Serve hot, garnished with extra cheese or fresh herbs if desired
