Ingredients
Main
- 3 lb beef skirt steak, sliced into strips
Vegetables
- 3 bell peppers (red, yellow, and orange), sliced
- 1 red onion, sliced
Sauce
- 60 ml blanco tequila
- 60 ml lime juice
Seasoning
- 2 tbsp chili-cumin rub
Serving
- flour tortillas, for serving
- sour cream, for serving
- pico de gallo, for serving
Why this recipe works
The slow cooker method works by maintaining a consistent, low-heat environment that slowly breaks down the fibers in the skirt steak. This process allows the meat to absorb the vibrant tequila and lime flavors while keeping it moist and tender. Because the liquid is trapped inside the closed vessel, the steam circulates effectively, ensuring that the bell peppers and onions retain their shape and structure while becoming infused with the aromatic spices of the chili-cumin rub.
This approach is highly effective because it minimizes the risk of overcooking or drying out the meat, which can often happen on a stovetop. By allowing the steak to simmer gently in its own juices and the added citrus marinade, the final result is consistently succulent.
The combination of high-heat searing during the prep phase and the long, slow simmer ensures that the fajita strips remain flavorful and soft, making them the perfect candidate for wrapping in warm flour tortillas.
Notes and substitutions
For the best results, use a high-quality skirt steak with visible marbling, as this fat will render down during the long cook time, adding immense depth of flavor. If you prefer a different cut, flank steak is an excellent substitute that will perform similarly in the slow cooker.
Ensure you slice your bell peppers and red onion into uniform strips so that they cook at the same rate. Freshly squeezed lime juice is recommended over bottled alternatives to ensure the brightest and most authentic flavor profile.
The equipment required for this recipe is simple: a standard oval-shaped slow cooker, a sharp chef knife for slicing the ingredients, and a pair of sturdy kitchen tongs for serving. No specialized tools or complicated techniques are necessary. If you find the sauce is too thin at the end of the cooking process, you can remove the meat and vegetables with a slotted spoon to concentrate the juices, or simply serve them with plenty of the flavorful liquid spooned over the top.
- blanco tequila: Use additional lime juice or chicken broth for an alcohol-free version.
- skirt steak: Flank steak or sirloin strips are suitable alternatives if skirt steak is unavailable.
