Ingredients

Why this recipe works

The slow cooker does all the work here. Cooking the brisket on low heat for hours breaks down the tough connective tissue, turning it into fork-tender strands that soak up the sauce.

The low, gentle heat also allows the peppers and onions to soften and sweeten, melding their flavors into the gravy without any stirring or babysitting.

The combination of sour cream and Dijon mustard creates a sauce that is both creamy and tangy, with a subtle sharpness that cuts through the richness of the beef.

The au jus adds depth and a savory umami note, while the peppers and onions provide natural sweetness and texture. This balance of flavors makes the dish satisfying without being heavy.

Notes and substitutions

Beef brisket is the ideal cut for this recipe because it becomes incredibly tender when cooked low and slow. Look for a brisket that is well-marbled and trimmed of excess fat. If you cannot find brisket, a chuck roast works well too. The peppers and onions should be sliced thick so they hold their shape during the long cooking time.

Whole-grain Dijon mustard gives the sauce a lovely texture and a milder heat than smooth Dijon. If you only have smooth Dijon, that works fine—just reduce the amount slightly. For a richer sauce, use full-fat sour cream. The au jus can be homemade or store-bought; low-sodium beef broth is a fine substitute if needed.
