Are you throwing a graduation party? Whenever I’m hosting a party, I always head to Costco- from party food platters to party appetizers, Costco makes it easy to throw an affordable graduation party. Here are the best Costco graduation party food ideas.
Costco Graduation Party Food Ideas
Caprese Skewers
Mozzarella tomatoes are my go-to party appetizers. If I’m short on time, I just serve the marinated fresh mozzarella balls with grape tomatoes in a bowl, and that’s it. But if I want to make the presentation a bit fancier, I’ll put them on little skewers and make caprese skewers. They’re the perfect appetizers for graduation parties.

Mozzarella Appetizers
These artisan wraps will be a big hit at your graduation party. They are perfect bite-sized appetizers available in three flavors. The wraps consist of fresh mozzarella wrapped in pepperoni, prosciutto, and sopressata. The best part is that no preparation is needed; just serve them on a nice platter, and you’re all set!

Chips and Guacamole
Chips and guacamole are always a hit at any party, especially graduation parties. Costco has the best price on tortilla chips and guacamole, so whenever I’m hosting a party, I will buy them there.

Tzatziki, Hummus and Naan
I like to add a little Mediterranean-inspired meze platter to the buffet table. I will assemble a platter with tzatziki, mini-naan bread, an assortment of olives, and hummus. It’s perfect for grazing during your graduation party.

Potstickers
Potstickers make for a simple and crowd-pleasing appetizer for your graduation party. They’re a hit with both kids and adults, and they’re filling, too.

Shrimp Cocktail
Make your graduation party extra special by serving shrimp cocktail. Costco has the best price on shrimp cocktails. If you have a lot of guests, order the party platter size for $39.99 (serves 20-24 people).


Mini Corn Dogs
Mini corn dogs are easy appetizers to serve at your graduation party. Both adults and kids will love them!

Caesar Salad
You can’t go wrong serving Caesar salad at your graduation party. It’s always a hit and holds up well on the buffet table, staying fresh throughout the event. I will either buy the Costco Caesar salad or the bag Caesar salad. I do feel like the salad in the clam shell looks fresher!

Chicken Alfredo
The Costco chicken alfredo is an easy and delicious pasta dish perfect for your graduation party. Although Costco packages the chicken alfredo in a small tray, you can easily transfer it to a 9×13 casserole dish, which it completely fills. I usually buy several chicken Alfredo trays and serve them in 9×13 casseroles or chafing dishes at my parties.

Burgers
Burgers are a hit at graduation parties. I like to serve grass-fed, frozen beef patties on Martin’s hamburger buns. These buns are my favorite because they’re made of potato bread, which gives them a soft and moist texture. I always get them from Costco because they offer the best price. Whenever I host a party, Costco is my go-to place to buy them.

Hot Dogs
If you’re firing up the grill for your graduation party, hot dogs are an easy party food addition. Costco makes it easy and affordable with bulk packs of high-quality hot dogs. Don’t forget to grab their club-sized packs of buns to match! To take it up a notch, set up a DIY hot dog bar with toppings like chili, shredded cheese, diced onions, sauerkraut, jalapeños, and a variety of mustards and relishes.

Spanakopita
These savory Greek pastries, filled with spinach and feta cheese, make an elegant addition to your graduation party spread. They come pre-made and frozen, so all you need to do is pop them in the oven for a few minutes before your guests arrive. They’re perfect for serving as an appetizer or as part of a buffet-style spread.

Mini Crab Cakes
Mini crab cakes will add a touch of sophistication to your graduation party. Costco offers frozen mini crab cakes that are easy to heat up and serve. With their golden crust and delicate, flavorful filling, these bite-sized treats are sure to impress your guests. Serve with a side of tangy tartar sauce or a spicy remoulade.

Mozzarella Sticks
Mozzarella sticks are always a hit at any party. These crispy, gooey cheese sticks are easy to prepare and come in affordable club-sized box. Whether you fry or bake them, they make a perfect party snack to keep guests happy while they mingle. Pair them with a marinara dipping sauce.

Charcuterie Board
Elevate your graduation party spread with a stunning charcuterie board. Costco makes it affordable to assemble your own with low prices on cured meats such as prosciutto, salami, and soppressata.

Costco also has low prices on artisanal cheeses like brie, gouda, and sharp cheddar. Add some fresh fruit, nuts, olives, and crackers to round out the board. Not only does it look impressive, but it’s also a versatile snack that guests can enjoy throughout the event.

Spinach Artichoke Dip
Spinach artichoke dip is a hit at any party. Available as a ready-to-heat, this dip can be quickly warmed up in the oven and served alongside pita chips, bread, or fresh veggies for dipping. It’s a great appetizer for your graduation party that’s sure to please everyone!

Sandwich Platter
Simplify hosting by ordering an Artisan Bread Sandwich platter from Costco. For just $49.99, you can feed 18 to 20 people with a variety of sandwiches featuring roasted chicken, roast beef, tomatoes, and herb aioli.

Cake
No graduation party is complete without a cake. Ordering a sheet cake from Costco is really affordable. It cost $24.99 for a half sheet cake which feeds 48 people. You can choose from white cake or chocolate cake. They will decorate it in a Graduation theme. One cake can easily feed your entire party!

Cookies
Order a cookie platter from Costco for your graduation party dessert. For just $22.99, you’ll get a big platter with 60 cookies. It comes in four flavors: chocolate chip cookies, white chocolate double nut, oatmeal raisin and white chocolate cranberry. Keep in mind that this cookie platter is not allergy-friendly, it contains macadamia and cashew nuts.

Ice Cream Bar
Costco is known for its variety of ice cream bars, and their selection is constantly evolving with new brands and flavors. You may find unique bars like this Afters Ube Brownie ice cream bar, which has gone viral on social media. Buy a variety of flavors and brands to satisfy every guest’s sweet tooth with minimal effort on your part—just serve and watch them disappear!

Polar Seltzer
Your grad is sure to love the packaging of these limited edition Polar Seltzers. They give that bubbly taste you crave without being overly sweet. They are sure to be a hit at your graduation celebration!

Honest Kids Juice Boxes
These Honest Kids juice boxes are my go-to juice boxes. I appreciate that they’re organic and contain less sugar than other juice box options. They also taste great, making them perfect for graduation parties.

Flowers
Don’t forget flowers for the grad. Costco sells a range of floral bouquets at great prices, some of which come arranged with a vase. They will make a beautiful addition to the buffet table and serve as a lovely centerpiece at your graduation party.

Candy Bar
You can easily make a candy bar at your graduation party. Just have your grad pick his/her favorite candies at Costco and then display them in clear vases. Voila!
