To make the gravy, melt the butter in a large skillet over medium heat.
Add the garlic and saute until the garlic is golden and fragrant.
Gradually whisk in the flour, stirring until flour is completely mixed in. Cook the flour for a few minutes to remove the raw taste.
Slowly stir in the chicken broth while whisking the entire time.
Stir in gravy seasonings.
Bring to a simmer and cook until the gravy thickens enough to coat the back of a spoon.
Taste the gravy and add more seasonings if desired. (remember the flavor will intensify as it cooks, so be careful not to over-salt)
Pour the gravy into the slow cooker.
Mix together the chicken seasonings and season both sides of the chicken generously.
Place the chicken into the slow cooker.
Place the lid on the slow cooker and cook on low for 5 hours. (may need more or less time) Shred the chicken during the last hour.
Taste and add more seasonings if desired.
Serve chicken over seasoned mashed potatoes, yellow rice, or herb pasta.
