So… you’ve got a party coming up. Maybe it’s a birthday, graduation, baby shower, or that random Saturday night when your cousin announces, “Hey, let’s invite everyone!” (and suddenly “everyone” means 30 people).
And here you are, staring at the fridge, realizing you definitely can’t whip up enough food for a crowd without losing your sanity.
That’s where Costco swoops in like the superhero of party food. The giant warehouse isn’t just about bulk toilet paper and oversized ketchup bottles, it’s secretly one of the easiest ways to feed a crowd without breaking the bank.
But here’s the catch: if you’ve never done it before, figuring out how to order Costco party platter can feel… well, confusing. Do you need to fill out a form? Do you just show up? How many people does that veggie tray actually feed?
Don’t worry. I’ve been down this road (a few times, actually), and I’m going to walk you through it, step by step, like a friend who’s got your back. Let’s talk trays, cakes, cookies, and those sweet Hawaiian rolls.
First Things First: How to Order Costco Party Platters
Okay, let’s tackle the big question right away: How do you actually order Costco party platters?
The process isn’t complicated, but Costco doesn’t exactly scream it from the rooftops either. Here’s what usually works:
This Is What the Costco Party Platter Order Form Looks Like

The official Costco Party Platter Order Form includes popular options like the Croissant Sandwich Platter ($32.99, serves 16–20), Chicken & Swiss Rollers ($32.99, serves 20–24), Shrimp Platter ($39.99, serves 20–24), and Meat & Cheese Platter ($26.99, serves 16–20). Just fill in your member details, pickup date, and quantity to place your order.
- Fill out the Costco Party Platter Order Form. You’ll choose the platter you want (they’ve got sandwich trays, shrimp platters, chicken wings, fruit, and more). You’ll also write down the pickup date and time.
- Grab the Costco Special Order Kiosk. Every Costco has one near the deli or bakery. It’s basically a station with order forms for things like cakes, sandwich platters, and yes, those beautiful trays.
Pro tip: They usually need at least 24 hours’ notice, but I always recommend giving them 48. Especially around holidays when everyone and their grandma is putting in orders. - Drop it off at the deli counter.
Super easy. No payment upfront, you just pay when you pick it up.
And here’s the part people often miss: You can’t order Costco platters online (at least not yet). It’s old-school. Pen, paper, hand it to a human.
I know… we live in the age of apps and one-click everything, but honestly, the process works. And it kind of guarantees freshness since you’re not placing an order weeks in advance that someone forgets about.
What Kinds of Costco Party Platters Can You Get?
This is where it gets fun (and slightly overwhelming if you’re hungry while reading this). Costco’s selection of party food platters is surprisingly solid. Here’s a peek at some of the most popular:
1. Costco Sandwich Platters
These are always a hit. You get a mix of chicken, roast beef, and turkey sandwiches on soft rolls. It’s like the grown-up version of a lunchbox, easy to grab, no forks needed.
2. Costco Shrimp Platter
If you’ve ever seen one, you know the shrimp are no joke. Big, plump, and served with cocktail sauce. Perfect for when you want to add a touch of “fancy” without actually cooking.
3. Costco Chicken Wings
Okay, I’ll be honest. These don’t always get the hype they deserve, but if your crowd loves wings, this platter saves you from frying 100 of them yourself.
4. Costco Vegetable Tray
Let’s talk about this one in detail because it’s a party classic.
The Costco vegetable tray (or Costco veggie platter, as some people call it) usually comes with carrots, celery, broccoli, cherry tomatoes, and snap peas, plus ranch dip. It’s fresh, crunchy, and gives your spread some color.
And here’s the detail everyone asks: Costco vegetable tray feeds how many?
On average, one tray serves about 20–25 people as a side/snack. If it’s the only veggie option, go with 20. If you’ve got other sides, it stretches further.
Don’t Forget the Sweets: Costco Cakes
Ah, Costco cakes. Honestly, these could have their own fan club.
Costco doesn’t just sell cakes, they sell giant, delicious, budget-friendly cakes that could feed a small army.
Here’s what you need to know:
- Costco Cake Sizes and Prices
The famous Costco sheet cake is 12” x 16” and serves about 48 people. And the price? Around $24 (seriously, it hasn’t changed much in years). That’s less than 50 cents per slice. - Costco Sheet Cake Price vs. Slab Cake
People sometimes confuse the terms. A “slab cake” is just another name for the Costco sheet cake. Same size, same price. - Costco Cake Ordering Form
Just like with platters, you fill out a paper form at the bakery. You can customize flavors (chocolate, vanilla, or marble) and add decorations or writing. - Mousse Cake Costco
Oh yes, don’t overlook this one. Their mousse cake is rich, layered, and feels fancier than a sheet cake. It’s pricier, but if you want to impress, it’s worth it.
Bonus Round: Other Costco Party Food Staples
Here’s where I admit something: half the time, I go into Costco for a platter and come out with a cart full of “extras” that suddenly feel essential for the party.
A few favorites:
- Costco Bakery Cookies Price
Those giant tubs of cookies? Perfect for parties. Soft, chewy, and ridiculously affordable. You get about 60 cookies for under $10. - Costco Hawaiian Rolls Price
Sweet, fluffy, and addictive. A 32-count pack usually runs around $6–$7. Pair them with ham and cheese, and suddenly you’ve got DIY mini sandwiches. - Finger Food Costco Party Food
Don’t sleep on the freezer section, meatballs, mini quiches, taquitos, and dumplings all make easy finger foods that keep guests happy.
Why Costco Party Platters Are a Lifesaver
Okay, let me be real for a second. The first time I ordered a Costco platter, it was for my niece’s birthday. I was already stressed about decorations, kids running wild, and that one aunt who always asks, “Do you have gluten-free options?”
Having those trays ready to go? Total game-changer.
Here’s why they work so well:
- Affordable. Compared to catering, you’re saving hundreds.
- Convenient. No cooking. No endless cleanup.
- Crowd-friendly. The variety means there’s something for everyone.
And honestly? People don’t care if the food came from a fancy caterer or a Costco tray. They’re just happy to eat and chat.
A Few Ordering Tips (From Someone Who’s Been There)
- Order early. Especially around the holidays. I’ve seen people show up day-of, only to be told the deli is slammed.
- Get extra dip. Trust me. The ranch on the veggie platter goes fast.
- Bring a cooler. If you’re driving far or picking up hours before the party, keep things fresh with ice packs.
- Mix and match. A sandwich platter + veggie tray + cookies = easy balanced spread.
FAQs About Costco Party Food Platters
Q: Can you order Costco platters online?
No, Costco party platters can’t be ordered online, you’ll need to visit your local warehouse and fill out a Costco Party Platter Order Form at the deli counter. It’s an old-school process (pen and paper), but it ensures freshness and accuracy. Some shoppers use Instacart or other third-party delivery apps to get trays delivered, but the official order still starts in-store.
Q: How much notice do they need?
Costco usually requires at least 24 hours’ notice to prepare party platters, though 48 hours is a safer bet, especially during busy seasons like Thanksgiving, Christmas, or graduation time. For example, the Costco Sandwich Platter or Costco Shrimp Platter often sell out quickly, so putting in your request two days ahead ensures you don’t miss out.
Q: Does Costco deliver party platters?
Costco itself doesn’t offer direct delivery for party platters. However, depending on your location, you might be able to use services like Instacart or Shipt to have trays brought to your door. Keep in mind, delivery fees and availability vary, and prices for some items (like the Costco Vegetable Tray or Costco Rotisserie Chicken Wraps Platter) can be slightly higher through third-party apps compared to in-store.
Q: Are Costco cakes really that cheap?
Yes! Costco cakes are famous for being both affordable and delicious. A full Costco Sheet Cake (12” x 16”) serves around 48 people and usually costs about $24.99. Compare that to many bakeries where a cake of the same size can cost $50–$70 or more. Costco also offers mousse cakes and seasonal options, though those are priced a bit higher. Either way, the Costco sheet cake price is one of the best party deals around.
Q: How many people does the Costco vegetable tray feed?
The Costco Vegetable Tray (sometimes called the Costco veggie platter) typically costs around $9.99–$10.99 and serves 20–25 people as a side or snack. It comes pre-packed with carrots, celery, broccoli, grape tomatoes, and snap peas, plus a generous cup of ranch dip. If it’s your only veggie option, plan on closer to 20 people.
