Before you start

Before starting, slice the skirt steak into thin strips across the grain, which helps ensure tenderness. Slice the bell peppers and red onion into similar-sized strips so they cook evenly.

Measure the lime juice and fajita seasoning. Soften the cream cheese by leaving it at room temperature for about 30 minutes, then cut it into chunks. Shred the cheddar cheese if not pre-shredded. Have a 6-quart slow cooker ready.

Ingredients at a glance (8)
  • 2 lb beef skirt steak, sliced into strips
  • 3 bell peppers (red, yellow, orange), sliced
  • 1 medium red onion, sliced into strips
  • 2 tbsp fresh lime juice
  • 8 oz cream cheese, softened and cut into chunks
  • 2 cups shredded sharp cheddar cheese
  • 2 tbsp fajita seasoning
  • cilantro-lime rice, for serving

Instructions

Layer and season

  1. Layer the raw ingredients
    Place the sliced skirt steak strips in the bottom of a 6-quart slow cooker. Scatter the sliced bell peppers and red onion strips over the meat. Drizzle with fresh lime juice. Sprinkle the fajita seasoning evenly over everything.
    Look for The meat and vegetables are evenly distributed in the slow cooker.
    Tip No need to stir; the slow cooker will blend the flavors as it cooks.
  2. Add the cheese
    Place the softened cream cheese chunks in the center of the slow cooker. Sprinkle the shredded sharp cheddar over the top. Do not stir; the cheese will melt and create a rich sauce during cooking.
    Look for The cream cheese and cheddar sit on top of the meat and vegetables.
    Tip Softening the cream cheese helps it melt more evenly.

At the end of this phase, the slow cooker contains raw skirt steak strips, sliced bell peppers, red onion, lime juice, and fajita seasoning, all layered evenly.

The cream cheese and shredded cheddar sit on top, looking like a white and yellow blanket over the colorful vegetables. The aroma is fresh and tangy from the lime, with a hint of spice from the seasoning. Nothing is stirred, and the ingredients are ready to cook.

Slow-cook to tender

  1. Slow-cook until tender
    Cover the slow cooker and cook on low for 6 to 8 hours, or on high for 3 to 4 hours, until the skirt steak is fork-tender and the peppers and onions are soft. The sauce will be bubbling and thick. Let it rest for 3 minutes before slicing.
    Look for The meat shreds easily with a fork and the sauce is creamy and bubbling.
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip Stir gently once at the end to combine the sauce; avoid over-stirring to keep the steak pieces intact.

After several hours, the slow cooker is bubbling gently, and the rich aroma of braised beef, peppers, and melted cheese fills the kitchen. The sauce is thick and creamy, with a golden-orange color from the cheddar and spices. The steak strips are tender and easily pull apart with a fork, while the peppers and onions have softened but still hold their shape. The surface is glossy, and steam rises in fragrant wisps.

Rest and serve

  1. Rest and serve
    Turn off the slow cooker and let the meat rest for at least 3 minutes. Serve the steak and vegetables with a generous spoonful of the creamy cheddar sauce over cilantro-lime rice.
    Look for The sauce is smooth and the steak is tender.
    Tip Letting the meat rest before serving keeps it juicy.

The slow cooker is turned off, and the dish rests for a few minutes. The sauce has settled into a smooth, velvety consistency, and the meat is juicy and tender. When served over cilantro-lime rice, the colorful peppers and onions contrast with the creamy sauce. The first spoonful reveals a perfect balance of savory beef, sweet peppers, tangy lime, and rich cheese. The plate is steaming and inviting.

Common mistakes

One common mistake is adding too much liquid, which can make the sauce thin and watery; the meat and vegetables release enough moisture as they cook. Another is cooking on high for too long, which can make the meat dry or stringy; low heat is gentler.

Avoid lifting the lid repeatedly, as that lets heat escape and extends cooking time. Finally, do not stir the ingredients before cooking, as the cheese needs to melt slowly on top to create a smooth sauce.

How to tell it’s done

The dish is done when the skirt steak is fork-tender and can be easily shredded or cut with a spoon. The internal temperature of the meat should reach at least 145°F (63°C) for food safety, but for maximum tenderness it will likely be higher after the long cook.

The peppers and onions should be soft and slightly caramelized, and the sauce should be thick, creamy, and bubbling. Let the meat rest for at least 3 minutes before serving.

  • Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
