Skirt steak is a flavorful cut that becomes incredibly tender when cooked low and slow. Combined with the bright acidity of fire-roasted tomatoes, the tangy heat of pickled jalapeños, and the creamy richness of queso blanco and pepper jack, this dish is a fiesta in every bite.

The slow cooker does all the work, turning simple ingredients into a comforting, crowd-pleasing meal. Serve it with tortilla chips and rice for a complete dinner that feels special but takes almost no effort.

Ingredients

Why this recipe works

Slow cooking transforms tough skirt steak into fork-tender bites. The low heat breaks down the connective tissue, resulting in meat that shreds effortlessly and soaks up all the surrounding flavors.

This method also allows the tomatoes and jalapeños to meld into a rich, zesty sauce that coats every strand of beef.

The combination of queso blanco and pepper jack creates a creamy, slightly spicy cheese sauce that binds the dish together.

Queso blanco adds smoothness, while pepper jack brings a subtle kick. As the cheeses melt into the tomato mixture, they form a luxurious sauce that clings to the meat and chips alike.

Notes and substitutions

Skirt steak is the star here, but flank steak or sirloin also work well. Look for slices that are uniform in thickness so they cook evenly. If the steak is very thick, consider cutting it into smaller strips. The key is to let the slow cooker do the work — no browning needed.

Fire-roasted diced tomatoes with green chiles add a smoky depth that regular diced tomatoes lack. Pickled jalapeños bring tang and heat; adjust the amount to suit your spice preference. Queso blanco dip is found in the refrigerated section, and any brand works. Shred your own pepper jack for the best melt.
