Ingredients

Why this recipe works

Slow cooking is the secret to transforming skirt steak, a cut that can be tough when cooked quickly, into fork-tender strips.

The low, moist heat of the slow cooker breaks down the meat's connective tissue, making it succulent and easy to pull apart. Meanwhile, the peppers and onions soften without losing their shape, and the lime juice brightens the rich flavors.

The combination of cream cheese and sharp cheddar creates a luscious, creamy sauce that clings to every piece of meat and vegetable. As the cheeses melt slowly, they emulsify with the meat juices and lime, forming a smooth queso-like sauce.

This method requires no pre-cooking, no stirring, and no extra pans, making it one of the simplest ways to get a deeply flavorful dinner on the table.

Notes and substitutions

Choose skirt steak that is well-marbled for the best texture; if it is too lean, it may dry out during the long cook. Slicing the steak into strips before cooking helps it absorb the seasonings and cook evenly. Bell peppers in red, yellow, and orange add sweetness and color, while red onion provides a mild bite that mellows as it cooks.

Use a good-quality fajita seasoning or make your own with chili powder, cumin, and garlic powder. The cream cheese should be softened to room temperature for smoother melting, though it will still melt if added cold. Sharp cheddar adds a bold flavor; for a milder sauce, use Monterey Jack. Serve over rice, in tortillas, or on a bed of greens.

• beef skirt steak: Flank steak or sirloin strips work well; adjust cooking time if using a leaner cut.
• fajita seasoning: Use 1 tbsp chili powder, 1 tsp cumin, 1 tsp smoked paprika, 1/2 tsp garlic powder, and 1/2 tsp salt.
• sharp cheddar: Monterey Jack or a Mexican cheese blend melts smoothly and adds a milder flavor.
• cilantro-lime rice: Warm flour tortillas, tortilla chips, or cauliflower rice are great alternatives.
