There's something magical about starting a brand-new year with the aroma of slow-cooked pork wafting through your kitchen. After fifteen years of perfecting this recipe, I can confidently say these Slow Cooker Pork Carnitas have become our family's New Year's Day tradition—and once you taste them, you'll understand why.
I still remember the first January 1st after my husband and I bought our house. We were exhausted from holiday entertaining, craving something comforting yet celebratory, and desperately wanted a meal that would feed a crowd without chaining us to the stove. That morning, I rubbed a pork shoulder with warm spices, tucked it into our trusty slow cooker with citrus and aromatics, and by dinnertime we were assembling the most incredible burritos I'd ever tasted. The pork was impossibly tender, caramelized at the edges, and infused with layers of flavor that tasted like they'd been developing for days.
Now, every New Year's Eve before the ball drops, I prep the spice rub and set out the slow cooker so we can wake up to the promise of something extraordinary. Whether you're feeding family who stayed over after last night's celebration, hosting a casual New Year's Day gathering, or simply want to treat yourself to an incredible meal that practically cooks itself, these carnitas will transform your holiday into something truly memorable.

Ingredients You'll Need
The magic of these carnitas lies in the quality of your ingredients and how they work together. Let's break down each component so you understand why each element matters and how to choose the best options at your market.
The Star: Pork Shoulder
Also sold as pork butt or Boston butt, this well-marbled cut comes from the upper shoulder of the pig. Despite the confusing names, it's actually perfect for slow cooking because the generous fat content and connective tissue break down during the long cooking process, creating incredibly tender, juicy meat. Look for a 4-5 pound boneless roast with good marbling throughout. If you can only find bone-in, that's fine too—just plan on it feeding slightly fewer people since the bone adds weight.
The Spice Rub: Building Layers of Flavor
Our signature blend combines warm, earthy, and bright notes that complement rather than overpower the pork. Brown sugar provides caramelization and balance, while smoked paprika adds depth. Ground coriander and cumin bring authentic Mexican flavors, and a touch of cinnamon adds warmth. Don't skip the oregano—Mexican oregano if you can find it, as it has a more robust, slightly citrusy flavor than Mediterranean varieties.
Citrus: The Brightness Factor
Fresh orange and lime juice aren't optional here—they're essential. The acidity helps tenderize the meat while adding brightness that cuts through the richness. The zest is equally important, as it contains aromatic oils that provide intense citrus flavor without additional liquid. Always zest your citrus before juicing, and choose fruit that feels heavy for its size with smooth, firm skin.
Aromatics: The Flavor Foundation
Onion, garlic, and jalapeño create the aromatic base that infuses the cooking liquid. The onion breaks down during cooking, naturally thickening the juices. Garlic adds pungency that mellows into sweet complexity. Jalapeño provides gentle heat—leave the seeds and membranes if you like it spicier, remove them for a milder version.
How to Make Slow Cooker Pork Carnitas for New Year's Day Burritos
Prepare the Spice Rub
In a small bowl, combine 2 tablespoons brown sugar, 1 tablespoon kosher salt, 2 teaspoons smoked paprika, 2 teaspoons ground coriander, 1 teaspoon ground cumin, 1 teaspoon dried oregano, ½ teaspoon black pepper, ¼ teaspoon cinnamon, and ⅛ teaspoon cayenne pepper. Mix thoroughly with a fork, breaking up any brown sugar lumps. This makes about ¼ cup of rub, which is perfect for a 4-5 pound pork shoulder. The rub can be made up to a week in advance—store it in an airtight container at room temperature.
Season the Pork
Pat your pork shoulder dry with paper towels—this helps the rub adhere and promotes better browning. Place the pork on a large cutting board or in a rimmed baking sheet. Generously coat all surfaces with the spice rub, massaging it into every crevice. Don't be shy here; use all the rub. The pork should be completely covered with a thick, even coating. If you have time, let the seasoned pork rest at room temperature for 30-45 minutes before cooking, or cover and refrigerate overnight for even deeper flavor penetration.
Create the Aromatic Base
While the pork is resting, prepare your aromatics. Dice 1 large onion (about 1½ cups), mince 6 cloves of garlic, and finely chop 1 jalapeño. If you're sensitive to heat, remove the seeds and membranes from the jalapeño; for extra heat, leave them in. The vegetables don't need to be perfectly uniform—they'll break down during cooking—but try to keep them roughly the same size so they cook evenly. Set aside while you prepare the citrus.
Prepare the Citrus Mixture
Zest 2 oranges and 2 limes before juicing them—you should get about 2 tablespoons orange zest and 1 tablespoon lime zest. Juice the zested fruit; you need ½ cup orange juice and ¼ cup lime juice. In a medium bowl, whisk together the citrus juices and zests with 2 tablespoons tomato paste, 1 tablespoon Worcestershire sauce, and 1 teaspoon salt. The tomato paste adds umami depth and helps create a rich cooking liquid that will later become your sauce.
Assemble in the Slow Cooker
Scatter the diced onion, minced garlic, and chopped jalapeño in the bottom of a 6-quart slow cooker. Place the seasoned pork shoulder on top of the vegetables, fat side up. Pour the citrus mixture around the pork—don't pour it directly over the top, as you want to keep that beautiful spice rub intact. Add ½ cup chicken broth or water to the slow cooker. The liquid should come about 1 inch up the side of the pork; add more if needed, but don't submerge the meat completely.
Slow Cook to Perfection
Cover and cook on LOW for 8-10 hours or HIGH for 4-5 hours. The pork is done when it's fork-tender and easily shreds with gentle pressure. Resist the urge to lift the lid during cooking—each peek releases heat and can add 15-20 minutes to your cooking time. If your slow cooker runs hot, check at the lower end of the time range. The pork should reach an internal temperature of at least 195°F for optimal shredding, but 200-205°F will give you even more tender results.
Shred and Crisp
Carefully remove the pork to a large cutting board or rimmed baking sheet. Using two forks, shred the meat into bite-sized pieces, discarding any large pieces of fat. Strain the cooking liquid through a fine-mesh sieve into a bowl, pressing on the solids to extract maximum flavor. Let the liquid settle for 5 minutes, then skim off excess fat from the surface. For authentic crispy edges, spread the shredded pork on a large rimmed baking sheet and drizzle with ½ cup of the defatted cooking liquid. Broil 4-6 inches from the heating element for 5-8 minutes, until the edges are crispy and caramelized.
Serve and Enjoy
Toss the crispy pork with additional cooking liquid to keep it moist and flavorful. Serve immediately in warm flour tortillas with your favorite burrito toppings. The pork will continue to absorb flavors as it sits in the liquid, making leftovers even more delicious. Store leftover carnitas in their cooking liquid in the refrigerator for up to 4 days, or freeze in portions for up to 3 months.
Expert Tips
Low and Slow is Key
While the HIGH setting works in a pinch, cooking on LOW develops deeper flavors and more tender meat. The collagen in the pork needs time to break down into gelatin, which creates that luxurious, silky texture.
Don't Skip the Liquid
Even though pork shoulder has plenty of fat, you need some liquid in the slow cooker to create steam and prevent the bottom from burning. The cooking liquid becomes liquid gold for keeping leftovers moist.
Broiling Makes It Authentic
The final broiling step isn't optional if you want authentic carnitas texture. Those crispy, caramelized edges provide contrast to the tender interior and add incredible depth of flavor.
Make-Ahead Magic
Season the pork and refrigerate overnight before cooking. This dry-brining technique seasons the meat throughout and helps it retain moisture during the long cooking process.
Trim Strategically
Don't remove all the fat from the pork shoulder—leave about ¼ inch layer. This bastes the meat as it cooks, keeping it moist and adding flavor. You can always remove excess fat after cooking.
Size Matters
If your pork shoulder is larger than 5 pounds, increase the spice rub proportionally. For smaller roasts, don't reduce the aromatics—they create the flavorful cooking liquid that keeps everything moist.
Variations to Try
Coca-Cola Carnitas
Replace the orange juice with Mexican Coca-Cola (made with cane sugar) for a sweeter, more caramelized version popular in Mexico. The cola's phosphoric acid helps tenderize the meat while adding subtle vanilla and caramel notes.
Chipotle Carnitas
Add 2-3 chipotle peppers in adobo sauce (minced) to the slow cooker along with 1 tablespoon of the adobo sauce. This variation adds smoky heat and rich complexity that pairs beautifully with the citrus notes.
Beer-Braised Version
Replace the chicken broth with a dark Mexican beer like Negra Modelo. The beer's maltiness adds depth and helps create a rich, velvety sauce. Add a bay leaf for extra aromatic complexity.
Tropical Twist
Add ½ cup diced fresh pineapple to the slow cooker along with the other ingredients. The pineapple's enzymes help tenderize the meat while adding subtle sweetness that balances the spices.
Storage Tips
Refrigerator Storage
Store leftover carnitas in their cooking liquid in airtight containers for up to 4 days. The liquid keeps the meat moist and flavorful. Separate into meal-sized portions for easy reheating. Always let the pork cool completely before refrigerating, but don't leave it at room temperature for more than 2 hours.
Freezer Instructions
Freeze carnitas in portion-sized containers or freezer bags with their liquid for up to 3 months. Press out excess air from bags before sealing. Label with the date and contents. Thaw overnight in the refrigerator for best results, though you can defrost in the microwave in a pinch.
Reheating Methods
For best results, reheat carnitas in a skillet over medium heat with a splash of the reserved cooking liquid. This helps restore moisture and creates new crispy edges. Microwave works for individual portions—cover and heat in 30-second intervals, stirring between each. For large quantities, reheat covered in a 350°F oven for 20-25 minutes.
Frequently Asked Questions
Pork shoulder is ideal because of its fat content and connective tissue, but pork butt works interchangeably (they're actually the same cut from different angles). Pork loin will be too lean and dry out during the long cooking process. If you must use loin, reduce cooking time by half and add more liquid, but expect a different texture.
Dry carnitas usually result from cooking at too high temperature or not enough liquid. Make sure you're using the LOW setting and have at least ½ cup liquid in the slow cooker. Also, don't skip the final step of tossing the shredded meat with cooking liquid. If your pork was very lean, next time choose a cut with more marbling.
Absolutely! Use the sauté function to sear the seasoned pork first, then cook on high pressure for 90 minutes with natural release for 15 minutes. The flavor will be similar, though you won't get quite the same depth as the long slow cooking process. After pressure cooking, shred and broil as directed for crispy edges.
The pork is ready when it reaches at least 195°F internal temperature and shreds easily with two forks. If it still feels tough or doesn't shred easily, it needs more time. Connective tissue breaks down between 195-205°F, so don't rush this step. The pork should practically fall apart when you touch it.
You can double the recipe if you have a large enough slow cooker (at least 8-quart capacity). The cooking time will remain the same, but make sure the pork fits without being too crowded. If you need to stack pieces, rotate them halfway through cooking. You'll also need to increase the spice rub proportionally.
Keep it simple to let the carnitas shine: warm flour tortillas, Mexican rice, refried beans, shredded lettuce, diced tomatoes, and queso fresco. Add pickled red onions for brightness and crema or sour cream for richness. Don't forget fresh cilantro and lime wedges for brightness, and offer salsa verde or pico de gallo on the side.
