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.

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 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.
