the flour and create the base for the creamy filling.
5. Create the Sauce
Slowly whisk in the beef broth and heavy cream, stirring continuously to prevent lumps. Allow the mixture to simmer gently, stirring often, until it thickens into a creamy sauce.
6. Mix in the Filling
Reduce the heat and add the shredded brisket, cheddar cheese, Monterey Jack cheese, thyme, salt, and black pepper. Stir until the cheese melts and everything is evenly combined and heated through.
Remove the mixture from the heat and allow it to cool
