Place roast along with garlic powder, seasoned salt, cayenne pepper, oregano, onion, dry onion soup, and broth in the crock pot. Cook on low for 8-10 hours or high for 4-6 hours.

Remove roast from crock pot to a plate and cover with foil to keep warm.

Melt butter in a medium saucepan. Whisk in tablespoons flour. Whisk in 4 cups of the liquid from the roast. If you are low on liquid you can use extra broth. Add a tsp or 2 of browning sauce if desired. Cook until it thickens to desired consistency. Serves 6-8.
