Ingredients

Why this recipe works

The magic of this dish lies in the low-and-slow cooking method. Cooking the pork shoulder on LOW for 8 to 10 hours breaks down the collagen in the meat, transforming a tough cut into fork-tender, pull-apart perfection.

The long cooking time also allows the onions to caramelize slowly, developing their natural sweetness and melding with the beef consommé to create a deeply savory, complex broth.

The butter is the secret to the silky, luxurious texture of the final jus. As it melts and emulsifies with the consommé and onion juices, it creates a rich, velvety sauce that clings to the pork. The high fat content of the pork shoulder also contributes to the moist, tender result, ensuring that every bite is juicy and full of flavor without any extra effort.

Notes and substitutions

Choose a boneless Boston butt pork shoulder, which is well-marbled and ideal for slow cooking. Vidalia onions are sweet and mild, but you can substitute other sweet onion varieties like Walla Walla or Maui.

If you only have yellow onions, they will work too, though the flavor will be slightly more pungent. Beef consommé is richer than regular broth, but beef broth can be used in a pinch—just adjust the salt accordingly.

You'll need a 6-quart slow cooker for this recipe. The roast should fit comfortably with room for the onions and liquid. No searing is required, which saves time and keeps the process simple. If you prefer a thicker jus, you can remove the pork and onions, then simmer the liquid on the stovetop to reduce it, but the natural consistency is already perfect for spooning over the meat.

• Vidalia onions: Sweet onions such as Walla Walla or Maui, or yellow onions for a sharper flavor.
• Beef consommé: Beef broth, but reduce salt in any additional seasoning since consommé is more concentrated.
• Salted butter: Unsalted butter plus a pinch of salt to taste.
