Ingredients

Why this recipe works

The slow cooker's low, steady heat breaks down the collagen in beef chuck cubes, transforming a tough cut into fork-tender, shreddable meat. This gentle cooking method allows the flavors of the fire-roasted tomatoes, pickled jalapeños, and cheeses to meld and penetrate the beef, creating a deeply savory and complex sauce.

Because everything cooks together in one pot, the juices from the beef combine with the tomatoes and cheese to form a rich, cohesive sauce without any extra steps.

Layering the ingredients in the order shown—beef on the bottom, then tomatoes, jalapeños, and cheese on top—ensures even cooking and prevents the cheese from scorching on the bottom of the pot. The queso blanco and pepper jack melt into a creamy, stretchy sauce that coats every shred of beef.

The pickled jalapeños add a bright, tangy heat that cuts through the richness, while the fire-roasted tomatoes provide a subtle smokiness. This simple assembly method yields a restaurant-quality dish with minimal effort.

Notes and substitutions

Beef chuck cubes are ideal for this recipe because they have enough marbling and connective tissue to become tender and flavorful during long cooking. If you can't find chuck cubes, stew meat or brisket cut into chunks works well. The fire-roasted diced tomatoes with green chiles (often sold as Rotel) add a smoky, slightly spicy base; if you prefer a milder flavor, use regular diced tomatoes and add a small can of diced green chiles separately.

Pickled jalapeños bring a tangy, vinegary heat that balances the creamy cheeses. For a spicier dish, use more jalapeños or leave the seeds in. The warm white queso blanco dip and shredded pepper jack cheese are both essential—they create the signature creamy, stretchy sauce. If you can't find queso blanco dip, substitute with shredded white cheddar or Monterey Jack. Use a 6-quart slow cooker to ensure everything fits comfortably and cooks evenly.
