Ingredients

Why this recipe works

The slow cooker does all the work here, gently coaxing the beef chuck to fall-apart tenderness over several hours. Low, moist heat breaks down the connective tissue in the meat, turning it into succulent shreds that soak up the salsa and spices. This method requires no searing or browning, saving time and effort while still delivering deep, developed flavor.

The layering technique is key: placing the beef on the bottom allows it to cook in its own juices and the salsa, while the cheese on top melts and blisters into a golden crust.

The beans and corn add texture and absorb the smoky sauce, creating a one-pot meal that's both comforting and vibrant. This is a true set-and-forget recipe that rewards you with a spectacular dinner.

Notes and substitutions

Beef chuck is ideal for slow cooking because it has enough marbling to stay moist and become tender. Look for pre-cut cubes or cut a chuck roast into 2-inch pieces. Rinsing the black beans removes excess sodium and ensures a cleaner flavor. Fire-roasted corn adds a smoky sweetness; if unavailable, frozen or canned corn works fine.

Oaxaca cheese is a Mexican string cheese that melts beautifully into long, stretchy strands. Combined with a Mexican four-cheese blend, it creates a rich, creamy topping.

If you can't find Oaxaca, mozzarella or Monterey Jack are good substitutes. Use a high-quality salsa for the best flavor—chunky roasted red tomato salsa adds depth and a slight smokiness.

• Oaxaca cheese: Mozzarella or Monterey Jack cheese can be used; both melt well and have a mild flavor.
• fire-roasted corn: Frozen corn kernels, thawed, or canned corn drained, work in a pinch.
• chunky roasted red tomato salsa: Use your favorite jarred salsa or homemade pico de gallo; adjust heat to taste.
• beef chuck cubes: Beef stew meat or brisket, cut into 2-inch pieces, are good substitutes.
