Before you start

Before starting, cut the pork shoulder into 1-inch cubes, slice the bell peppers and red onion, and juice the lime. Set out the sour cream and shredded cheese so they are ready to add. No other prep is needed; the slow cooker does all the work.

Ingredients at a glance (7)
  • 3 lb pork shoulder, cut into 1-inch chunks
  • 3 bell peppers (red, yellow, orange), sliced
  • 1 red onion, sliced
  • 2 tbsp fresh lime juice
  • 1/2 cup sour cream
  • 2 cups shredded Monterey Jack cheese
  • warm flour tortillas, for serving

Instructions

Layer and Forget

  1. Layer the Pork and Vegetables
    Place the cubed pork shoulder into the slow cooker insert in an even layer. Scatter the sliced bell peppers and red onion over the meat. Drizzle with fresh lime juice.
    Look for The pork and vegetables should be evenly distributed in the slow cooker.
    Tip Cut the pork into uniform 1-inch chunks so they cook evenly.
  2. Add the Creamy Toppings
    Dollop the sour cream over the pork and vegetables. Sprinkle the shredded Monterey Jack cheese evenly over the top. Do not stir.
    Look for The sour cream and cheese form a thick layer over the meat.
    Tip Leave the mixture undisturbed so the cheese melts into a creamy sauce.

At the end of this phase, the slow cooker contains a colorful layer of raw pork, peppers, onions, and lime, topped with dollops of sour cream and a blanket of shredded cheese.

The cheese looks bright and inviting, and the sour cream is visible in creamy swirls. Nothing is stirred; the layers are distinct and ready to cook.

Slow-Cook and Shred

  1. Slow-Cook Until Fork-Tender
    Cover the slow cooker and cook on low for 8 hours, or on high for 4-5 hours, until the pork is fork-tender and easily shreds. Let it rest for 3 minutes before slicing.
    Look for The pork should shred easily with a fork and the sauce should be bubbling.
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip Check at the minimum time; slow cookers vary, so rely on tenderness rather than time.
  2. Shred the Pork
    Remove the pork from the slow cooker and place on a cutting board. Using two forks, shred the pork into bite-sized pieces. Return the shredded pork to the slow cooker and stir to combine with the peppers, onions, and creamy sauce. Let it rest for 3 minutes before slicing.
    Look for The pork shreds easily and the sauce coats each piece.
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip Let the pork rest for a few minutes before shredding to retain moisture.

The slow cooker is bubbling gently, and the aroma of pork, peppers, and lime fills the kitchen. The pork is fork-tender and shreds easily.

The sauce is creamy and slightly thickened, with melted cheese and sour cream forming a cohesive sauce. The peppers and onions are soft and sweet.

Serve and Enjoy

  1. Serve with Warm Tortillas
    Warm the flour tortillas according to package directions. Spoon a generous portion of the carnitas mixture onto each tortilla. Serve immediately.
    Look for The tortillas are warm and pliable.
    Tip Warm tortillas in a dry skillet for a light char, if desired.

The carnitas are piled onto warm tortillas, with the creamy sauce glistening. The pork is tender, the peppers are soft, and the cheese is melted. Each bite is a balance of savory pork, tangy lime, and rich, creamy sauce. The dish is ready to be devoured.

Common mistakes

One common mistake is opening the slow cooker lid frequently, which lets heat escape and extends cooking time. Another is using pre-shredded cheese that may not melt smoothly.

Also, do not skip the lime juice—it balances the richness. Finally, cutting the pork too large can result in uneven cooking; stick to 1-inch chunks.

How to tell it’s done

The pork is done when it shreds easily with a fork and the internal temperature reaches at least 145°F (63°C).

Let it rest for at least 3 minutes before shredding. The sauce should be thick and creamy, and the peppers and onions should be tender but not mushy.

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