Slow-Cooker Pepper Jack Fajita Pork Carnitas

This slow-cooker dinner is the definition of set-it-and-forget-it. Tender pork shoulder simmers for hours in a bath of lime juice, bell peppers, red onion, and a creamy duo of queso blanco and pepper jack cheese.

The result is a bubbling, citrusy, slightly spicy carnitas that needs almost no effort. Perfect for busy weeknights or game-day spreads, it turns simple ingredients into a rich, satisfying meal.

Pork shoulder is the hero here, slowly braised until it falls apart. The bell peppers and onions soften into sweet, charred-style ribbons, while the queso blanco and pepper jack melt into a stretchy, savory sauce.

Lime juice brightens everything, cutting through the richness. Serve it over tortilla chips and Mexican rice for a complete meal that feels indulgent but comes together with minimal hands-on time.

Ingredients

Why this recipe works

Slow cooking transforms tough, well-marbled pork shoulder into succulent, shreddable meat. The low, gentle heat breaks down collagen and connective tissue, turning it into gelatin that keeps the meat moist and tender.

The long cook time also allows the lime juice and peppers to infuse every bite with bright, savory flavor.

The combination of queso blanco and pepper jack creates a sauce that is both creamy and tangy. Queso blanco melts smoothly without separating, while pepper jack adds a gentle heat and a gooey texture.

As the cheese simmers with the pork juices, it thickens into a rich, clinging sauce that coats every strand of meat.

Notes and substitutions

Choose a well-marbled pork shoulder (also labeled pork butt) for the best results. Leaner cuts can dry out during the long cook. Cut the pork into uniform chunks so they cook evenly. The peppers and onions should be sliced thinly, so they soften and meld into the sauce rather than staying crunchy.

Use a good-quality queso blanco dip that is smooth and pourable; if it is too thick, warm it before adding. Pepper jack cheese can be replaced with Monterey Jack plus a pinch of cayenne for a milder heat. Fresh lime juice is essential — bottled juice lacks the same bright, aromatic lift.

• pork shoulder: pork butt or pork picnic, cut into chunks; adjust cooking time if using a leaner cut.
• queso blanco dip: store-bought white queso or homemade queso; choose a mild version if preferred.
• pepper jack cheese: Monterey Jack with a pinch of cayenne, or a smoked gouda for a different flavor.
• fresh lime juice: bottled lime juice, but fresh is brighter and more aromatic.
