Chicago's Signature Foods: What Makes Them Special

Deep Dish Pizza: More Than Just Thick Crust

Chicago-Style Hot Dogs: A Strict Culinary Code

Ordering a what to eat in chicago without mentioning the iconic hot dog would be incomplete. The Chicago-style hot dog follows precise specifications established during the city's meatpacking heyday:

• All-beef frank (never pork or chicken)
• Poppy seed bun
• Mustard, neon green relish, chopped onions, tomato slices, pickle spear
• sport peppers and celery salt
• Strict "no ketchup" rule for anyone over 15

According to the Chicago History Museum, this configuration emerged in the 1920s as Jewish and Greek immigrants adapted their sausage traditions to American ingredients. The distinctive neon green relish was created during World War II when cucumber supplies were limited—food coloring made existing relish appear fresher.

Italian Beef Sandwiches: Soaked to Perfection

The chicago italian beef sandwich originated in the city's meatpacking district during the early 20th century. Butchers would give workers thin slices of roast beef as part of their pay, which they'd dunk into jus to stretch the meal. Today's version features:

• Thinly sliced seasoned roast beef
• Served on French bread
• Dipped in au jus ("wet" or "dipped")
• Often paired with sweet or hot peppers

Unlike imitations found elsewhere, authentic Chicago Italian beef requires the bread to absorb the jus without disintegrating—a delicate balance achieved through specific baking techniques developed over decades.

Frequently Asked Questions

What makes Chicago deep dish pizza different from regular pizza?

Chicago deep dish features a buttery, pan-baked crust (1-2 inches thick) with cheese layer directly on crust, toppings, then chunky tomato sauce on top. It's baked in a cast iron pan for 30-45 minutes, creating a casserole-like meal rather than a handheld pizza.

Why can't you put ketchup on a Chicago-style hot dog?

The 'no ketchup' rule for Chicago hot dogs (for anyone over 15) dates to the 1920s when immigrants considered ketchup a children's condiment. The precise topping arrangement—mustard, relish, onions, tomatoes, pickle, peppers, and celery salt—creates a balanced flavor profile that ketchup would disrupt.

What's the difference between Chicago-style and New York-style pizza?

Chicago deep dish has thick, pan-baked crust with sauce on top, while New York style features thin, foldable hand-tossed crust with sauce underneath cheese. Chicago pizza requires a knife and fork, takes 30+ minutes to bake, and serves as a complete meal, whereas New York slices are designed for quick, handheld eating.

Where did Chicago-style Italian beef sandwiches originate?

Italian beef sandwiches originated in Chicago's meatpacking district during the early 1900s. Butchers would give workers thin slices of seasoned roast beef as part of their pay, which workers would dunk into jus to stretch the meal. The tradition evolved into the dipped sandwich served on French bread that defines Chicago's food scene today.
