A deep half pan feeds about 25 people as a side and about 17 as a main. Cut foods like lasagna give 9 to 12 pieces. If you've seen "10 to 15" somewhere else, that figure assumes a shallower pan and a bigger portion — and the difference is worth knowing before you order or cook.
"Half pan" here means the standard half-size steam table pan — the disposable foil tray that goes in a chafing dish, or its stainless hotel-pan equivalent. It's about 12 by 10 inches, and it's what caterers price by and what most party hosts end up buying in packs of ten. The footprint is fixed. Three other things decide how many people it actually feeds.
Three Things That Change the Answer
Depth. Half pans are sold shallow, medium, deep and extra deep, and the extra-deep version holds more than twice what the shallow one does. "A half pan" isn't one size.
Portion. A side served with a ½-cup scoop and a main served at ¾ cup come out of the same pan at very different headcounts. This is the biggest variable, and the one most quoted figures leave out.
How many other dishes there are. On a buffet with three sides, people take less of each. A common caterer's rule of thumb is about 4 ounces of each side when there are two, and 3 ounces each when there are three or more. More dishes, smaller portions, more people per pan.
Servings by Pan Depth
Disposable foil half pans are rated by how much they hold to the rim. In service you fill to about an inch below the rim — roughly 80% — so that's what these figures use.
| Half pan | Holds to rim | In service | Side (½ cup) | Main (¾ cup) |
|---|---|---|---|---|
| Shallow | 84 fl oz (2⅝ qt) | 67 fl oz | 16 | 11 |
| Medium | 107 fl oz (3⅜ qt) | 86 fl oz | 21 | 14 |
| Deep | 128 fl oz (4 qt) | 102 fl oz | 25 | 17 |
| Extra deep | 195 fl oz (6 qt) | 156 fl oz | 39 | 26 |
Rim capacities are manufacturer figures as listed by foodservice suppliers. A full pan has the same footprint as two halves and holds a little over double.
Servings by Food (Deep Half Pan)
| Food | Typical portion | Servings |
|---|---|---|
| Baked beans, coleslaw — one of 3+ sides | #10 scoop, 3 fl oz | 34 |
| Mac and cheese, mashed potatoes, rice — side | #8 scoop, ½ cup | 25 |
| Mac and cheese or pasta as the main | ¾ cup | 17 |
| Pulled pork, meatballs in sauce — main | ¾ cup | 17 |
| Lasagna, baked ziti in squares — main | 3 × 4 in pieces | 9 |
| Casserole, cornbread — standard squares | 3 × 3 in pieces | 12 |
| Brownies, bars | 2 × 2 in pieces | 30 |
That spread — 9 to 34 from the same pan — is why a single "a half pan serves X" answer never holds up. A barbecue forum thread on this exact question has one caterer reporting 60 to 70 servings of beans from a pan that feeds about 40 with mac and cheese. The pan and the volume were identical; people simply take more mac and cheese.
How Many Half Pans for Your Party
Deep half pans, 10% extra for seconds:
| Guests | Servings to plan | Side (25 per pan) | Main (17 per pan) |
|---|---|---|---|
| 20 | 22 | 1 | 2 |
| 30 | 33 | 2 | 2 |
| 50 | 55 | 3 | 4 |
| 75 | 83 | 4 | 5 |
| 100 | 110 | 5 | 7 |
For other pans, portions or piece sizes, the catering pan calculator runs the same arithmetic. To pick a scoop that matches a target portion, see portion scoop sizes.
When You're Ordering From a Caterer
Menu figures like "half pan serves 10–15" are usually set for a main-course portion in a medium-depth pan, with a margin so nobody runs short. That's sensible for the caterer, but if you're ordering sides for a buffet with several dishes, it can lead you to buy nearly twice what you need. Ask two questions: how deep is the pan, and what portion is the serving count based on? With those, you can work out your own number in a minute.
Half Pans Beat Full Pans on a Buffet
A full pan holds about the same as two halves, so the choice is about service, not quantity. Two half pans let you put one out and keep the other hot in the oven, then swap — rather than leaving one big pan on the table as it cools. Hot food should stay at 140°F or above, and food that drops into the 40–140°F range shouldn't sit out for more than two hours (the two-hour rule). Half pans also fit standard chafing dishes two to a frame, so you can run two dishes side by side.
Frequently Asked Questions
How many people does a half pan of mac and cheese feed?
A deep half pan feeds about 25 as a side with a #8 scoop (½ cup), or about 17 if it's the main dish at around ¾ cup each.
How many pieces are in a half pan of lasagna?
A half pan is about 12 × 10 in: 9 main-course pieces of 3 × 4 in, or 12 standard pieces of 3 × 3 in.
How many half pans do I need for 50 people?
For a side at ½ cup each with 10% extra, 55 servings — three deep half pans. For a main at ¾ cup, four.
Why do caterers say a half pan serves 10 to 15?
Those figures usually assume a generous main-course portion and a shallower pan. Served as a side at ½ cup, a deep half pan stretches to about 25. Check what portion any quoted figure assumes.
