Illinois cuisine is anchored by Chicago’s legendary food scene, but the state’s agricultural roots and multicultural history also play a major role. These dishes define what people most associate with Illinois. Here are some of Illinois’s most famous dishes for you to try.
Chicago Deep‑Dish Pizza
Deep‑dish pizza is the most famous food from Illinois and a global icon of Chicago cuisine. Created in the 1940s, this pizza features:
- A tall, buttery crust
- Layers of mozzarella
- Chunky tomato sauce on top
- Optional fillings like sausage, pepperoni, or spinach
Restaurants like Giordano’s, Lou Malnati’s, and Gino’s East are synonymous with this dish. Deep‑dish is one of the most searched‑for Illinois food terms, making it essential in any guide to the state’s cuisine.
Chicago‑Style Hot Dog
The Chicago‑style hot dog is another culinary symbol of Illinois. This “dragged through the garden” creation includes:
- An all‑beef hot dog
- Poppy seed bun
- Yellow mustard
- Relish
- Onions
- Tomato slices
- Pickle spear
- Sport peppers
- Celery salt
One rule defines it: no ketchup. This dish is central to searches for what to eat in Chicago and remains a beloved street‑food classic. Despite its roots in Illinois, the Chicago Hot Dog is popular across the United States.
Italian Beef Sandwich
The Italian beef sandwich is a Chicago invention dating back to the early 20th century. Thinly sliced roast beef is simmered in seasoned jus, piled onto a long roll, and served:
- “Dry” (light jus)
- “Wet” (dipped)
- “Dipped” (fully soaked)
Toppings include sweet peppers or spicy giardiniera. It’s a staple of Illinois comfort food and a must‑try for visitors.
Chicago Cheesecake
Chicago‑style cheesecake is richer and creamier than its New York counterpart. Made with cream cheese and sour cream, it has a dense texture and smooth finish. Eli’s Cheesecake helped popularise this dessert, making it one of the most recognisable Illinois sweet treats.
Horseshoe Sandwich
Originating in Springfield, the horseshoe sandwich is a hearty Illinois classic. It features:
- Thick slices of toasted bread
- A meat of choice (hamburger, ham, chicken, or pork)
- A pile of fries
- A generous pour of cheese sauce
It’s indulgent, messy, and beloved across central Illinois.
Pierogi
Chicago’s large Polish community helped make pierogi a staple of Illinois cuisine. These dumplings—filled with potato, cheese, sauerkraut, or meat—are served at festivals, diners, and family gatherings. They’re a key part of Illinois immigrant‑influenced foods.
Pork Tenderloin Sandwich
Popular throughout the Midwest, the pork tenderloin sandwich is especially beloved in rural Illinois. A thin, breaded pork cutlet is fried until crisp and served on a bun—often much smaller than the meat itself. It’s a favourite at diners and county fairs.
Garrett Popcorn
Garrett Popcorn, founded in Chicago, is famous for its “Garrett Mix”—a blend of caramel and cheese popcorn. This sweet-savoury combination is a signature Illinois snack food and a popular gift for visitors.
Apple Cider Doughnuts
Illinois’ orchards make apple cider doughnuts a seasonal favourite. Soft, spiced, and coated in cinnamon sugar, apple cider doughnuts are especially popular in autumn and can be found at pumpkin patches, farmers’ markets, and fall festivals.
