In your slow cooker place your stew beef, potatoes, carrots, onion and pepperoncini's.

In a small bowl mix together the ranch packet and 1 of the brown gravy packets with 1 cup of water and whisk together.

Pour the mixture into the slow cooker.

Stir everything together.

Place the stick of butter on top.

Cover and cook on low for 6-8 hours or high for 4-6 hours.

When the meat and veggies are tender stir in the last packet of brown gravy mix to thicken up the gravy.

I like to serve this over egg noodles, but it is also great over rice or mashed potatoes.
