During the Peoria Diocese's Annual Catholic Schools Week, Seton Catholic School holds the annual Seton Spaghetti Dinner and Basket Raffle. Catholic Schools Week usually is the last week of January. The Seton Community of family and friends come together for this fun event. Happy Joe's caters the spaghetti and pizza for this gathering held in Culemans Hall. Drinks and desserts are also available. Seton families and friends are invited to come enjoy a meal, visit with friends, and buy chances for nearly 30 fabulous themed baskets of goodies.
Each year the Basket Raffle Committee comes up with creative new themes for the homeroom baskets. The students and families are invited to donate items or money for their homeroom basket(s). Each year the committee does the creative work of assembling the baskets for presentation at the dinner.
All those in attendance at the Spaghetti Dinner have the option to purchase chances for the various baskets on display. Near the end of the evening, a winner for each basket is drawn. Throughout the evening there are also carnival games for the students.
