Taking the time to make a smooth, thick gravy for this slow-cooked dinner is worth it. As the pot roast cooks, the water and juices from the vegetables and meat will thin the gravy out, creating just the right consistency.
Achieving a deep, golden-brown crust on the chuck roast is crucial for developing rich flavor; don't rush this step. The 'brick-red' stage of the tomato paste is also key, indicating the sugars have caramelized and deepened its umami. While the gravy may seem thick initially, it will thin out beautifully with the meat and vegetable juices during the long slow cook. Always slice the roast against the grain for maximum tenderness. For an elevated presentation, consider garnishing with a sprinkle of fresh chives or a dollop of horseradish cream alongside the parsley. Avoid over-handling the beef once it's tender, as it can easily fall apart.
