How many pounds of carnitas do I need for 100 guests?

For 100 guests eating a standard taco buffet (3 tacos / 6 oz cooked meat each), you need 58 to 60 lbs of raw boneless pork shoulder, or 65 to 68 lbs of bone-in pork shoulder. This yields approximately 37.5 lbs of shredded cooked carnitas.

Why Carnitas Loses 35% of Its Raw Weight

Authentic Mexican carnitas are made from pork shoulder (also called pork butt or Boston butt). This cut is rich in intramuscular connective tissue, collagen, and fat cap. During the 3-to-5 hour slow braise:

Pork Cut Format	Bone & Trim Loss	Cooking Rendering Loss	Cooked Yield per 1 lb Raw	Raw Needed for 100 Tacos
Boneless Pork Shoulder (Boston Butt)	0% (intact roast)	35% rendering loss	10.4 oz cooked	19.2 lbs raw
Bone-In Pork Shoulder	12–14% blade bone	35% rendering loss	9.0 oz cooked	22.2 lbs raw

The Sheet-Pan Broiler Crisping Secret for Large Parties

Great carnitas have contrast: ultra-tender, juicy interior shreds with crispy caramelized edges. When serving large gatherings:

Phase 1: Slow Braise

200°F Internal Temp

Slow-cook with orange juice, Mexican oregano, and cumin until fork-tender. Coarsely shred with tongs.

Phase 2: High Broil

4–6 Mins on Sheet Pan

Spread shreds in a single layer on rimmed sheet pans. Broil on HIGH until crispy golden tips caramelize.

Phase 3: Citrus Glaze

Ladle Broth in Pan

Toss crispy shreds in 1/2 cup of warm citrus braising juices before transferring to buffet hotel pans.

How Many Pounds of Carnitas Per Person? (Raw vs. Cooked Pork Shoulder)

Because pork shoulder (Boston butt or picnic roast) contains a heavy fat cap and significant connective collagen that melts away during hours of slow cooking, cooking shrinkage averages 35% for boneless roasts and 42% for bone-in roasts. Plan with these exact per-person benchmarks:

Guest Count	Target Cooked Carnitas (6 oz/person)	Raw Boneless Pork Butt (35% shrinkage)	Raw Bone-In Pork Shoulder (42% shrinkage)	6-Quart Slow Cookers Needed
10 Guests	3.75 lbs (60 oz)	5.8 – 6.0 lbs raw	6.5 – 7.0 lbs raw	1 slow cooker
25 Guests	9.40 lbs (150 oz)	14.5 – 15.0 lbs raw	16.0 – 17.0 lbs raw	2 slow cookers
50 Guests	18.75 lbs (300 oz)	29.0 – 30.0 lbs raw	32.5 – 34.0 lbs raw	3 to 4 slow cookers
100 Guests	37.50 lbs (600 oz)	58.0 – 60.0 lbs raw	65.0 – 68.0 lbs raw	Commercial roaster / 2 full hotel pans

Per-Person Quick Ratio: For standalone carnitas tacos without heavy sides, purchase 0.58 lbs (9.3 oz) raw boneless pork per guest. When serving accompanied by Mexican rice, refried beans, and chips, scale back to 0.40 lbs (6.4 oz) raw pork per guest.

Frequently Asked Questions About Pork Carnitas

For a standard meal (3 tacos / 6 oz cooked carnitas), plan for 9.2 oz (approx. 0.58 lbs) of raw boneless pork shoulder, or 10.5 oz (0.65 lbs) of bone-in pork shoulder. Pork shoulder experiences 30% to 40% cooking shrinkage from rendering fat and bone weight.

For 50 guests eating a standard carnitas taco meal (150 tacos total), you need 29 to 30 lbs of raw boneless pork butt (yielding ~19 lbs of shredded cooked carnitas), or 33 to 35 lbs of bone-in pork roast.

Boneless pork butt has an average shrinkage of 32% to 35%. Bone-in pork shoulder has an average shrinkage and scrap rate of 38% to 42% once the blade bone and heavy exterior fat cap are discarded.

Pork shoulder is rich in intramuscular connective tissue and collagen. As it braises past 200°F (93°C), collagen breaks down into gelatin, keeping the meat moist in slow cookers for 3 to 4 hours without drying out.

Because carnitas are rich and savory, they pair best with high-acid accompaniments: fresh salsa verde made with tart roasted tomatillos, pickled red onions, fresh lime wedges, and cilantro.

For 100 guests eating a standard taco buffet (3 tacos per person), you need 48 to 50 pounds of raw bone-in pork shoulder (or 40 pounds boneless). At 35% cooking shrinkage, this yields 30 to 32 pounds of tender, pulled carnitas (approx. 5 oz per guest).
