Carnitas might be the single best thing you can make with a Boston butt in a crockpot.
The pork cooks low and slow until it collapses into tender, juicy shreds, infused with citrus, cumin, and mild green chiles.
Then — if you want the full experience — a few minutes under the broiler crisps the edges until they’re golden and slightly crunchy, giving you that contrast of soft and crispy in every bite.

Why These Crockpot Boston Button Recipes Work
Boston butt is built for the crockpot. The shoulder is full of connective tissue that melts into gelatin during a long, moist cook, giving carnitas their rich, juicy texture instead of dry shreds.
Citrus does the heavy lifting. Fresh orange juice and lime juice add brightness and help tenderize the pork without making it taste sweet.
Green chiles add mild heat and depth. A can of diced green chiles brings a gentle, earthy warmth that pairs perfectly with cumin and chili powder.
Searing first builds flavor — but it’s optional. A quick sear gives the pork a deeper, roastier flavor. Skip it, and this becomes a true dump-and-go recipe that still works beautifully.
The broil step is what makes it carnitas. Traditional carnitas are crisped after braising. A few minutes under the broiler transforms tender shredded pork into something with textural contrast — soft inside, crispy edges.
It’s high-protein and meal-prep friendly. One batch gives you taco night, burrito bowls, nachos, and lunches for days. It freezes perfectly in 1–2 pound portions.
It feeds a crowd. A 4–5 pound roast makes enough for 8–10 generous servings. This game-day crockpot recipe scales easily.
Crockpot Boston Button Recipes: Fall-Apart Pork Carnitas
Tender, citrus-braised Boston butt (pork shoulder) with Mexican spices and green chiles, shredded and crisped under the broiler for the ultimate taco filling.
Ingredients
- 4–5 lbs boneless pork butt (Boston butt/pork shoulder), trimmed of excess fat and cut into 4–5 large chunks
- 1 tbsp vegetable or olive oil (for searing, optional)
- 1 tbsp kosher salt
- 1 tsp black pepper
- 2 tsp garlic powder
- 1 tbsp ground cumin
- 1 tbsp chili powder
- 1 tsp smoked paprika
- 1 tsp dried oregano
- 1 cup chicken broth
- ½ cup fresh orange juice (about 1 large orange)
- ¼ cup fresh lime juice (about 2 limes)
- 4 cloves garlic, minced
- 1 can (4 oz) diced green chiles
- 1 yellow onion, chopped
- 2 bay leaves
- Fresh cilantro, diced onion, avocado, and lime wedges, for serving
Instructions
- Prep the pork. Pat the pork dry with paper towels and season all over with salt, pepper, and garlic powder.
- Sear the pork (optional but recommended). Heat oil in a large skillet over medium-high heat. Sear the pork on all sides until golden brown, about 3–4 minutes per side. Transfer to the slow cooker. This step adds a deeper, roastier flavor, but you can skip it entirely and still get excellent results.
- Add the spices and liquids. In a small bowl, mix cumin, chili powder, smoked paprika, and oregano. Sprinkle over the pork. Add chicken broth, orange juice, lime juice, minced garlic, green chiles, chopped onion, and bay leaves to the slow cooker.
- Cook low and slow. Cover and cook on low for 8–10 hours or on high for 5–6 hours, until the pork shreds easily with a fork. It should reach an internal temperature of 200–205°F.
- Shred the pork. Remove the pork from the slow cooker, discard the bay leaves, and shred with two forks. Skim excess fat from the cooking liquid. Return the shredded pork to the liquid and toss to coat.
- Crisp the carnitas (optional but highly recommended). Spread the shredded pork on a foil-lined baking sheet in a single layer. Drizzle with a few tablespoons of the cooking liquid. Broil on high for 5–8 minutes, watching closely, until the edges are crispy and golden. For extra crispy carnitas, broil in two batches so the pork isn't crowded.
- Serve. Serve in warm corn tortillas with diced onion, fresh cilantro, avocado, and a squeeze of lime. Or use the pork for burrito bowls, nachos, quesadillas, or meal prep containers.
Tips for the Best Crockpot Pork Carnitas
Use Boston butt, not pork loin. Boston butt (pork shoulder) has the marbling and connective tissue that make carnitas tender and juicy. Pork loin is too lean and will dry out.
Cut the pork into large chunks. This helps it cook more evenly and gives the spices and citrus more surface area to penetrate.
Don’t add too much liquid. The pork releases a lot of its own juices. One cup of broth plus the citrus juices is plenty. More liquid dilutes the flavor and prevents the meat from caramelizing.
Let it rest before shredding. Cover the cooked pork with foil and let it rest 15–20 minutes before shredding. The juices redistribute, and the meat stays moister.
Skim the fat. The cooking liquid will have a layer of fat on top. Skim it off before tossing the pork with the juices, or the final dish will taste greasy.
Save the cooking liquid. Toss a few tablespoons of the defatted braising liquid with the shredded pork to keep it moist and add back flavor. This is especially important for meal prep.
Shred while warm. Pork shreds much more easily when it’s hot. If it cools too much, it becomes stringy and harder to pull apart.
Broil in batches for maximum crispiness. If you crowd the baking sheet, the pork steams instead of crisps. Spread it in a single layer and work in batches if needed.
Don’t skip the citrus. The orange and lime juice are what make carnitas taste like carnitas. Bottled juice works in a pinch, but fresh is noticeably better.
Easy Variations
Crockpot Pork Carnitas Bowls
Serve the carnitas over rice or cauliflower rice with black beans, corn, pico de gallo, avocado, and a lime wedge. This high-protein,, gluten-free meal holds up for 4 days in the fridge.
Carnitas Tacos with Crispy Tortillas
Dip white corn tortillas into the defatted cooking liquid, then pan-fry them in a skillet over medium heat until browned on both sides. Fill with crisped carnitas and Chihuahua cheese, then cook until the tacos are crispy. Flip a few times while they crisp.
Slow Cooker Carnitas Nachos
Spread tortilla chips on a baking sheet, top with shredded carnitas and cheese, and broil until the cheese melts. Finish with diced onion, cilantro, jalapeño, and a drizzle of crema.
Carnitas Meal Prep Bowls
Divide rice or cauliflower rice among containers, top with carnitas, black beans, corn, and salsa. Keep avocado and lime separate until serving. Reheat the pork and rice; add the cold toppings fresh.
Boston Button Recipes Oven Version
If you don’t have a crockpot, roast the seasoned pork in a Dutch oven at 300°F for 4–5 hours, covered, until it reaches an internal temperature of 200–205°F. Shred and broil as directed. The results are very similar.
Storage and Reheating
Store shredded carnitas with a few tablespoons of defatted cooking liquid in an airtight container in the refrigerator for 3–4 days. Reheat gently in a covered skillet or in the microwave with a splash of broth or water until it reaches 165°F.
To freeze: Cool completely, then freeze in 1–2 pound portions in freezer bags or containers for up to 3 months. Thaw overnight in the refrigerator before reheating. This is one of the best meals to have stashed in the freezer for busy weeknights.
Food safety note: Don’t leave cooked pork at room temperature for more than 2 hours. If you’re serving this at a game day party or cookout, keep it on a warming tray or in a slow cooker set to warm.
Frequently Asked Questions
What is Boston butt?
Boston butt is the upper part of the pork shoulder. Despite the name, it’s not from the rear of the pig — the name comes from the barrels, called “butts,” that colonial-era New Englanders packed pork shoulder into for shipping. It’s the same cut as pork shoulder and pork butt, and it’s the classic choice for carnitas.
Is “Boston button” the same thing as Boston butt?
Yes. “Boston button” is a common misspelling and search variation of Boston butt. If you’re shopping, look for a roast labeled Boston butt, pork butt, or pork shoulder — they’re all the same cut.
Is pork carnitas high in protein?
Yes. Cooked pork shoulder provides about 22–25 grams of protein per 3-ounce serving, making it an excellent choice for high-protein meals and meal prep.
Bone-in or boneless for carnitas?
Both work. Bone-in adds flavor and moisture and is usually cheaper, but boneless is easier to fit and shred. This recipe works with either.
Do I need to sear the pork first?
No, but it adds flavor. The sear gives the pork a deeper, roastier taste, but you can skip it entirely and still get tender, flavorful carnitas. If you have 10 extra minutes, it’s worth it.
How long do I cook pork carnitas in the crockpot?
A 4–5 pound roast cooks on low for 8–10 hours or on high for 5–6 hours. The pork is done when it reaches 200–205°F and shreds easily with a fork.
Can I use frozen pork butt?
It’s not recommended. Frozen meat takes too long to reach a safe temperature in the slow cooker, which increases the risk of bacterial growth. Thaw it first.
Why is my carnitas dry?
Usually because it was cooked too long without enough liquid, or because you trimmed the fat too aggressively. Leave some fat on the roast, and don’t exceed 10 hours on low for a 4–5 pound roast.
Can I make these carnitas in an Instant Pot?
Yes. Cut the pork into large chunks, add 1 cup of liquid, and cook on high pressure for 50–60 minutes, then let it release naturally. Then broil as directed for crispy edges.
Are these carnitas gluten-free?
Yes, as written, if you use gluten-free broth and check your spices. Always check labels on broth and seasoning blends.
Can I make these carnitas dairy-free?
Yes. None of the ingredients in this recipe contain dairy. Just skip the cheese when serving.
What do I serve with carnitas?
Warm corn tortillas, diced onion, fresh cilantro, avocado, lime wedges, salsa, pickled red onions, and crumbled queso fresco or cotija cheese.
Can I make this for a crowd?
Absolutely. This is one of the best crockpot meals for a crowd. A 4–5 pound roast serves 8–10 people generously. Double the recipe if you have a larger slow cooker.
