The Strategy
Slow cookers make the most tender pot roasts, but they leave behind a lot of thin, watery juices that need a little sweet talk to turn into gravy. Mixing equal parts of flour and soft butter together creates a magic paste that thickens the sauce without leaving any lumpy flour pockets. Just whisk it right into those bubbling juices and watch it transform into a rich, glossy gravy, honey.
Technique Summary
Swirling a smooth paste of butter and flour into hot slow cooker juices is the absolute best way to make a glossy, lump-free gravy. It thickens the broth beautifully while adding a rich, velvety finish that clings to every bite.
