Crispy carnitas need a second cook after the braise. Drain the pork and dry it off, then spread it in a single layer under high heat. Cook’s Illustrated broils shredded pork on a rack for 5 to 8 minutes per side, and Serious Eats’ sous vide carnitas get their crust in a skillet in about 10 minutes.
In Michoacan, the pork cooks and crisps in the same pot of lard, so the fat does all the frying. Most home kitchens can’t pull that off, so the job gets split into a braise and a finish under the broiler or in a skillet. An air fryer works for that second half too.
Milk Street’s 2019 carnitas recipe points out that the usual US method of simmering and shredding pork gives you moist meat but skips the crisping the dish is known for. A braise alone never builds the crust.
What makes carnitas crispy?
Water leaving the surface of the cooked pork, and then hot fat well above 212 degrees F. That’s the whole mechanism. Tender meat is the easy half, and the crust is its own cooking step.
Browning on meat is the Maillard reaction, and it speeds up at roughly 300 degrees F and above.
Water in an open pot can’t get hotter than 212 degrees F. A wet surface just steams until the moisture is gone, which is why pork lifted straight out of a braise turns gray in a pan instead of brown.
Why a braise alone stays soft
Liquid caps the temperature at its boiling point. The meat gets tender and never browns.
Milk Street makes the same point about simmering and shredding: moist pork, but none of the crisping that’s traditional to carnitas. Its own recipe pairs the simmer with a fat-based finish for that reason.
That finish is also what separates carnitas from pulled pork, the Southern US dish that stops at tender.
How the traditional cazo method gets there
Carnitas as made in Michoacan start with chunks of fatty pork simmered in lard in a copper cazo. It’s closer to confit than to a braise, since the fat cooks and crisps the pork in one pot. Rick Bayless told Tasting Table that the fully traditional version takes four gallons of lard and bone-in shoulder cut into two-pound chunks.
Cazo cooking is only one of the styles of carnitas you will run into, but it sets the benchmark for the crust: fat bubbling around every piece until the outside turns golden.
Home kitchens copy the effect with a hot skillet or a broiler.
Choosing the pork and fat for carnitas that crisp
Pork shoulder, which US stores often sell as Boston butt, is the right cut, and lard or the pork’s own rendered fat is the right cooking fat. Both choices come down to fat. Shoulder carries enough of its own to render and brown.
Cutting the shoulder
Cut chunks of 2 to 3 inches so each piece keeps a juicy center. Leave most of the fat cap on, since it renders into the crisping fat. Bone-in works as well as boneless, and Bayless uses bone-in for the traditional version.
Lean cuts like loin brown fine and then dry out, which keeps the list of cuts that work best for carnitas short.
Lard, rendered fat or oil
Lard is what the cazo runs on, so it’s the traditional pick.
J. Kenji Lopez-Alt’s no-waste recipe for Serious Eats skips the extra lard. Tasting Table describes the trick: pack the shoulder chunks tightly into a baking dish so they render enough fat to cook in their own drippings.
When there’s no rendered fat to spare, a neutral oil in the pan does the job for the final crisp.
Rubs, citrus and sugar
Season dry, and put the sugar in the braise rather than at the end.
Wet marinades add water that has to cook off before browning starts. A dry rub avoids that, and a reliable carnitas seasoning blend covers the flavor.
Orange juice and milk belong in the braise, and so does soda, since their sugars caramelize as the liquid cooks down. Tasting Table reports that Cosme, the New York restaurant known for its duck carnitas, adopted Coca-Cola and evaporated milk after seeing street stalls use them to caramelize the fat.
How to braise carnitas so they crisp afterward
Use the least liquid the pot allows, and stop when a fork pulls a chunk apart with almost no pressure. Less liquid in the pot means less to boil off before the crisp.
| Method | Published time | Watch for |
|---|---|---|
| Oven or stovetop pot | 4 hours start to finish (Milk Street) | Watery pot if the lid stays on too long |
| Slow cooker | 6 hours cook time (Gimme Some Oven) | Pooled liquid that needs draining |
| Instant Pot | 1 3/4 hours total, fast version (Milk Street) | Pork that falls apart before it can hold a crust |
In the oven, keep it low, around 325 degrees F, and leave the lid on. If your oven or recipe works in Celsius, you can convert oven temperatures between Fahrenheit and Celsius in seconds.
USDA’s Food Safety and Inspection Service set whole cuts of pork at 145 degrees F with a 3-minute rest in 2011, and a carnitas braise sails past that mark long before the shoulder is tender.
So tenderness ends the braise, not the thermometer.
Pull the pork the moment it shreds easily. Go past that point and the meat turns mushy and won’t hold a crust.
Drying and draining the pork before the crisp
Lift the pork out of the braise, drain it, and let the surface dry before it meets high heat. Skipping this is the most common reason a batch comes out soft.
- Lift the chunks out with a slotted spoon onto a wire rack set over a sheet pan, so steam escapes from every side.
- Skim the fat off the braising liquid and save it for the crisping pan.
- Boil the remaining liquid down in a separate pot until it turns into a thick, syrupy glaze. Cook’s Illustrated does the same, reducing the liquid for 8 to 12 minutes until a spatula leaves a wide trail.
- Shred the pork into large, coarse pieces, or leave the chunks whole for a juicier center.
- Rest the pork uncovered for a few minutes and blot the surface with a paper towel.
- Spread the pieces in a single layer with space between them, because crowded pieces steam each other.
Sources disagree a little here. Isabel Eats drizzles reserved cooking liquid over the shredded pork before broiling, while America’s Test Kitchen’s slow-cooker recipe moistens the pork with liquid on the serving platter.
The platter method keeps the crust intact. Every spoonful added before the crisp pulls the surface back toward 212 degrees F.
Which crisping method works best: broiler, skillet, sheet pan or air fryer?
The broiler wins for a pan-sized batch, a cast iron skillet wins on crust depth, and an air fryer suits a single portion. Pick by batch size first and by equipment second.
| Method | Heat and time | Best for | Main limit |
|---|---|---|---|
| Broiler | High, 5 to 8 minutes per side (Cook’s Illustrated) | A whole pan of shredded pork | Burns fast if left alone |
| Cast iron skillet | Medium, about 10 minutes (Serious Eats) | Deepest crust | One layer at a time |
| Sheet pan roast | About 450 degrees F for 30 minutes (Jo Cooks) | Ovens without a broiler | Slowest, dries lean pieces |
| Air fryer | 400 degrees F, about 12 minutes (Hola Jalapeno) | Single portions | Small basket |
Broiler
Cook’s Illustrated spreads the shredded pork on a wire rack inside a rimmed baking sheet, sets it on the lower-middle rack, and broils 5 to 8 minutes on each side.
Go by color, not the timer. Broilers differ in output, and rack distance changes the clock.
Cast iron skillet
Heat the skillet over medium to medium-high heat with a spoon of the saved fat. Add the pork in one layer and leave it alone until the underside browns, then turn the pieces and start the next batch.
Serious Eats offers two routes for its sous vide carnitas: about 10 minutes in a cast iron or nonstick skillet over medium heat, or about 10 minutes with the pan 3 inches under a high broiler.
The skillet gives the deepest crust. The price is rounds, since a big pot of carnitas never fits in one.
Sheet pan in a hot oven
An oven without a working broiler can still crisp carnitas.
Jo Cooks roasts the pork at about 450 degrees F for 30 minutes in that case. It’s the slowest route, and the lean pieces dry out first.
Air fryer and Instant Pot air fryer lid
The air fryer lid on Instant Pot’s Duo Crisp tops out at 400 degrees F, and Hola Jalapeno’s carnitas recipe runs it there for 12 minutes, turning the pork halfway.
Engadget’s 2020 review of the Instant Pot Air Fryer Lid found it works as promised, but only for small batches. Keep the pork in a single layer and shake or turn it partway, which is what Ninja’s quick start manual advises for even browning.
Recipes written for the oven need new settings in the basket, so it pays to convert oven settings to air fryer settings before you start.
Why are carnitas soggy, dry, burned or greasy?
Each failure traces back to one main cause, and the fix is usually a single change on the next batch.
| Symptom | Main cause | Fix |
|---|---|---|
| Soggy | Surface water still on the pork | Drain, dry, crisp in one layer |
| Dry | Lean pieces, or too long under the heat | Pull earlier, add a spoon of rendered fat |
| Burned | Rack too close to the element | Lower the rack, watch the pan |
| Greasy | Pork sitting in its own fat | Crisp on a rack so fat drips away |
Reading the pan
Sound tells you where a batch stands. A loud, steady sizzle means water is still boiling off the surface. A quieter crackle means the surface has dried and is starting to brown.
Under the broiler, color does the same job. Stay at the oven door, because carnitas go from crisp to charred in a short window.
Greasy results
Cook’s Illustrated broils its carnitas on a rack for exactly this reason. Excess fat drips off, which cuts the greasiness without cutting the pork flavor.
A rack still leaves enough fat on the pork to help the crisp.
What a crisp step cannot repair
The crisp changes the surface and nothing else.
Pork that’s still tough inside, or already dry, stays that way under a crunchy crust. Put it back in the pot for more braising time, or chop it into a saucy filling instead.
How to re-crisp leftover carnitas
Re-crisp leftover carnitas in a hot skillet, under the broiler, or in an air fryer, and add fat rather than liquid. A skillet gives the most control.
Store the pork in a shallow, airtight container with some of the cooking fat. Per the USDA Food Safety and Inspection Service, it goes into the refrigerator within 2 hours of cooking and should be eaten within 3 to 4 days. When you reheat it, the pork needs to reach 165 degrees F, checked with a food thermometer.
Rick Bayless notes that slow-cooked carnitas can sit wrapped in the refrigerator for several days before browning. USDA caps cooked pork at 3 to 4 days, so treat 4 days as the ceiling.
Serious Eats’ no-waste recipe crisps its pork straight from the refrigerator, so there’s no thawing step.
For the skillet, use medium-high heat and a spoon of fat, add the cold pork in one layer, and turn it once the underside browns. In the air fryer, preheat the basket, spread the pork in a single layer and shake it once halfway. Check early, since small amounts crisp in minutes.
Some reheating guides add broth to keep the pork from drying out, and others stick to oil in the pan. Broth suits a taco filling that doesn’t need crunch. For a crust, fat wins, because liquid pulls the surface back toward the boiling point.

Crispy Carnitas FAQ
How do you crisp store-bought or Costco carnitas?
Skip the braise and go straight to the crisp step. Spread the precooked pork in a large skillet over medium heat and let it caramelize and crisp at the edges, which is what the Roli Roti ready-to-heat carnitas directions call for.
A separate walkthrough covers cooking Costco carnitas step by step.
Can you make crispy chicken carnitas?
Yes. Shred the cooked chicken, spread it in an even layer and broil it for about 5 to 6 minutes, as Gimme Some Oven does for its slow cooker chicken carnitas.
Chicken carries less fat than pork shoulder, so it dries out sooner. Stay at the oven.
Can carnitas get crispy in the microwave?
No. A microwave warms the pork but can’t brown it, because the wet surface never climbs past the boiling point of water.
Fifteen Spatulas notes that microwaved carnitas come out less crispy. Use the microwave to warm them, then finish in a skillet.
Is deep frying a good way to crisp carnitas?
Yes, and it’s close to the traditional route. Hank Shaw of Honest Food cooks the pork in lard at about 195 degrees F until tender. If he doesn’t plan to reuse the lard, he heats it to 350 degrees F and fries the pork until the exterior is crispy.
To reuse the lard, he removes all but about 1 cup and sears the pork in that instead.
How long can you freeze carnitas?
USDA’s Food Safety and Inspection Service puts cooked leftovers at 3 to 4 months in the freezer for best quality, though they stay safe indefinitely.
Freeze the pork before crisping, thaw it in the refrigerator, then crisp it as usual.
Serving Crispy Carnitas to a Crowd
Crispy carnitas for a crowd come from braising the pork ahead and crisping it in rounds, one pan at a time, with the final round finished just before serving.
A broiler round takes 10 to 16 minutes (5 to 8 minutes per side, per Cook’s Illustrated), while a skillet batch takes about 10 (Serious Eats). The broiler wins on volume per round, not speed. That sets the order of work. Braise and refrigerate the pork ahead, crisp the early rounds and hold them, then crisp the last round at serving time.
USDA’s Food Safety and Inspection Service says hot food stays safe at 140 degrees F or warmer, so held pans go into a warm oven. The trade-off is a softer crust on every pan that waits.
Sizing the braise comes first, so work out how much pork to braise per guest before cooking.
