Local Cuisine and Culinary Traditions
Toasted Ravioli
Toasted ravioli is a quintessential St. Louis specialty. Despite its name, this dish consists of breaded ravioli that are deep-fried until golden and crunchy, then served as an appetizer topped with grated Parmesan cheese and accompanied by a side of marinara sauce for dipping . The ravioli can be filled with various ingredients, with popular options including beef, cheese, spinach, or eggs . Food experts trace its origin to the 1950s at a restaurant called Angelo Oldani's, where it was created and quickly became a local staple . Today, it's a beloved appetizer found in Italian restaurants and eateries throughout the city.
St. Louis-Style Pizza
St. Louis-style pizza is a unique regional variation that sets itself apart from other pizza styles. It features an extremely thin, cracker-like crust that is cut into small squares or rectangles rather than traditional wedges . The defining characteristic, however, is the use of Provel cheese, a processed cheese blend combining provolone, Swiss cheese, and white cheddar that provides a distinctive creamy and slightly smoky flavor . Most versions of this pizza trace their inspiration to Imo's, a popular local pizza chain that has become synonymous with the style .
Gooey Butter Cake
Gooey butter cake stands as a hallmark dessert of St. Louis, originating in the southern part of the city where many German bakers once lived . This flat, dense cake is made from wheat flour, butter, sugar, and eggs, creating a texture similar to a brownie—sweet, firm, and topped with a characteristic gooey layer . According to local legend, it was accidentally invented during the 1930s Depression era when a baker making a yellow cake added too much sugar, butter, or shortening. Unable to waste ingredients, he sold the resulting "gooey, sticky mess," and it became an instant success . It is traditionally garnished with powdered sugar and sometimes served with raspberries .
Slinger
Known locally as a "Wilbur" and sometimes described humorously as a "culinary car crash," the slinger is a hearty St. Louis specialty particularly famous as a hangover cure . Traditionally served for breakfast or lunch, it typically consists of two hamburger patties topped with fried eggs, served alongside fried potatoes or hash browns, all covered generously with chili and garnished with grated cheese and chopped onions . Hot sauce is usually offered on the side. Variations may include tamales, veggie burgers, white gravy, or toasted bread .
Frozen Custard
While frozen custard originated in Coney Island, New York, as a carnival treat, it has become deeply embedded in Midwestern food culture, including St. Louis . Made with eggs, cream, and sugar, frozen custard contains less air than regular ice cream, resulting in a thicker, denser, and exceptionally flavorful dessert . It is served before being refrozen, maintaining a soft, heavy consistency that many enthusiasts prefer over traditional ice cream .
St. Louis-Style Ribs
St. Louis has given its name to a specific cut of pork ribs that has become a barbecue standard. St. Louis-style ribs are pork spare ribs trimmed down into uniform, almost perfectly rectangular pieces of meat . Before grilling, they are typically seasoned with salt or a dry rub of spices. They are then cooked slowly and brushed with a sticky, sweet, and slightly acidic tomato-based barbecue sauce until tender and juicy . They are often served with extra sauce for dipping and represent the city's significant contribution to American barbecue culture .
Contemporary Culinary Scene
St. Louis's dynamic food scene continues to evolve, as celebrated by St. Louis Magazine's annual A-List Awards. Recent standout dishes include modern Italian fare at Marconi Mercato on The Hill, featuring Ravioli Al Funghi (delicate house-made mushroom-stuffed ravioli), Carciofi Fritti (crispy fried artichokes), and Lombatello (marinated hanger steak) . The Lucy Quinn / Little Lucy concept in The Grove offers bold comfort food like smoked turkey leg, roasted cabbage, and Big Baby Q Pastrami, a nod to the city's barbecue tradition . An innovative addition is Crispy Sips, a mobile soda bar creating inventive non-alcoholic "dirty sodas" with bold flavor infusions, with popular mixes including "Dr. Dreamy" and "It's Giving Witchy" .
