Ingredients for carnitas roast pork

Pork shoulder, citrus, and smoky spices transform into restaurant-quality carnitas with crispy edges and melt-in-your-mouth shreds.

The pork shoulder is your star—look for well-marbled cuts with good fat cap at Whole Foods or your butcher shop. If buying pre-cut, check for even 2-inch chunks. Costco often has great deals on whole shoulders if you're feeding a crowd. For the lard, rendered pork fat gives unmatched crispiness, but vegetable shortening works in a pinch. Fresh citrus is non-negotiable here—the juice should be bright and vibrant, not cloudy. If you can't find fresh limes, Key lime juice from the store is the next best thing. The spices? Penzeys or bulk bins for maximum freshness—ground spices lose potency fast after opening.

No fresh limes? Substitute bottled lime juice with extra salt—about 1/4 tsp more per 1/4 cup. Running low on lard? Butter or bacon fat works in a bind, though it'll be slightly less crisp. The cinnamon sticks are optional but add that authentic Mexican cantina vibe. For the vinegar, apple cider vinegar adds subtle sweetness if you prefer. The bay leaves might seem minor, but they're what gives that subtle earthy depth to the slow-cooked meat. If you're short on time, pre-cut pork shoulder from the grocery store's deli section saves hours of butchering.

This carnitas keeps beautifully—3-4 days in the fridge, 3 months frozen. For crispy edges, always reheat at high heat in a skillet with a splash of oil. I portion mine into quart-sized containers so I can grab and go for tacos all week. The fat rendering process creates a golden crust that's best enjoyed fresh, but the shredded meat stays tender for days. Store any leftover marinade separately—it's perfect for brining chicken or as a quick marinade for shrimp.

Step-by-step instructions for crispy carnitas roast pork

Here's how to transform tough pork shoulder into melt-in-your-mouth carnitas with that coveted crispy bark.

Start by cutting the 6 lb pork shoulder (Boston Butt) into 2-inch chunks, leaving the bone-in for better moisture retention and flavor. Pat each piece completely dry with paper towels - this step is non-negotiable for crispy bark. I press firmly to remove all surface moisture that would otherwise steam instead of crisp.

In a large bowl, combine the 0.5 cup lard (or vegetable shortening) and 0.5 cup neutral vegetable oil. This fat blend is crucial - the lard gives authentic carnitas flavor while the oil prevents burning during the high-heat sear. Warm this mixture in a saucepan over low heat until just melted, then let cool slightly for easier handling.

In a separate mixing bowl, whisk together the 1 cup freshly squeezed orange juice, 0.5 cup freshly squeezed lime juice, 0.25 cup white vinegar, 2 tbsp ground cumin, 1 tbsp smoked paprika, 1 tbsp garlic powder, 1 tsp dried oregano, 1.5 tbsp salt, and 1 tsp black pepper. The acidity from the citrus and vinegar will tenderize the meat while the spices create that signature carnitas depth.

Add the 2 whole bay leaves and 2 whole cinnamon sticks to the marinade. These aromatic elements infuse subtle earthy and warm spice notes that elevate the dish. Pour this marinade over the pork chunks, ensuring every piece is well-coated. Cover and refrigerate for at least 4 hours, or preferably overnight - this long marinating time is what makes the difference between good carnitas and exceptional carnitas.

Preheat your oven to 325°F. In a large Dutch oven or heavy pot with a lid, place the pork chunks in a single layer. Pour the melted fat mixture over the pork, then cover and transfer to the oven. Cook for 1 hour, then increase heat to 375°F and uncover the pot.

This is where the magic happens - the uncovered cooking at higher temperature allows the fat to render out and create that coveted crispy bark. After 30 minutes at 375°F, you'll see the edges starting to brown and crisp. I like to give it a gentle shake of the pot every 15 minutes to ensure even browning on all sides. The pork is ready when it reaches an internal temperature of 195°F and the meat pulls apart easily with two forks.

Remove the pork from the oven and let it rest for 10 minutes. Using two forks, shred the pork directly in the Dutch oven, breaking it down into 2-inch shreds. The meat should be so tender it practically falls apart at the touch - this is the hallmark of perfect carnitas. Remove and discard the bay leaves and cinnamon sticks.

Return the shredded pork to the pot along with any accumulated juices. Over medium heat, add the pork fat and juices that have rendered out during cooking. Let this mixture simmer for 5-7 minutes until slightly reduced and the pork is thoroughly coated in the flavorful fat. The result should be pork that's both tender and crispy, with a sauce that clings perfectly to each shred.

Oaxacan Tradition

In Oaxaca, Mexico, carnitas originated as a way to preserve pork during the rainy season. The traditional method uses pork fat (up to 50% of the recipe) and slow-cooks the meat for hours until it becomes tender and crispy.

I learned from my friend Chef Elena in Oaxaca City that the key is using guajillo chiles in the marinade—about 2-3 dried chiles soaked and blended—to add subtle heat and depth.
