You know about the Philly cheesesteak. You’ve probably tried a Cuban at some point. Maybe a po’boy if you’ve visited New Orleans. These are the famous ones, the sandwiches that get all the airtime on food shows and travel blogs. They’ve earned their spots in America’s culinary hall of fame.
Here’s the thing though. The United States is massive, and tucked away in corners you’d never think to look are sandwiches so regional, so specific, that even people from neighboring states have never heard of them. Some exist only in one city. Others barely make it beyond a single neighborhood. They’re the deep cuts of American food culture, waiting to be discovered. Let’s dig into six of these hidden gems that deserve way more attention than they’re getting.
The Mother-in-Law Sandwich from Chicago’s Southside
This Southside Chicago sandwich has a history as fascinating as its name, featuring a hot dog bun that holds a commercially made hot tamale, covered in chili. Let’s be real, that’s not what most people expect when you say sandwich. Chicago’s unique hot tamales made their journey north from the Mississippi Delta with African Americans over a century ago. The name remains a bit of a mystery, though theories abound about why anyone would name a sandwich after their mother-in-law. Try one at Fat Johnnie’s Famous Red Hots if you’re brave enough to venture into this unusual territory.
The St. Paul Sandwich Hiding in St. Louis
Funny enough, the St. Paul sandwich can only be found in St. Louis, not Minnesota, and was created by the city’s Chinese-American immigrants at their restaurants in the area. It’s an unusual Chinese-American sandwich composed of an egg foo young patty with lettuce, tomato, onion, pickles and mayonnaise between two slices of white sandwich bread, reportedly invented by a chef hailing from Minnesota in the 1940s to attract local customers unaccustomed to Chinese cuisine. The contrast here is wild. You’re biting into something that feels like a classic American diner sandwich, yet there’s this crispy egg patty with bean sprouts bringing completely different flavors to the party. It shouldn’t work, but somehow it absolutely does.
Nebraska’s Deep Fried Cheese Frenchee
This little-known variation on the grilled cheese sandwich is deep fried for the ultimate crispy, melty experience, with the cheese sandwich cut into triangles, then dipped in egg batter and breading (which often includes corn flakes cereal) before getting thrown in the deep fryer. Think about that for a second. Someone looked at a perfectly good grilled cheese and thought, you know what this needs? A full baptism in hot oil. Get one at Don and Millie’s, a small fast food chain in Omaha and Lincoln. It’s indulgent, probably terrible for you, and exactly the kind of Midwest comfort food that makes you understand why people stay in Nebraska through brutal winters.
The Gerber from St. Louis
St. Louis shows up twice on this list, which tells you something about that city’s willingness to experiment. The Gerber was invented at Ruma’s Deli in the early 1970s when a customer named Dick Gerber had it made to order, and it’s a toasted, open-faced ham and cheese sandwich on crispy Italian bread with garlic butter, with the special ingredient being Provel cheese, a processed cheese that’s a hybrid of provolone, cheddar, and Swiss, and specific to the area. You literally cannot make an authentic Gerber outside of the St. Louis region because the cheese doesn’t exist anywhere else. Talk about regional specificity. Some say this sandwich isn’t truly a Gerber unless you’re eating it at the source, which feels like the kind of food gatekeeping I can actually respect.
Michigan’s Cudighi Sausage Creation
Most pizzerias, delis, and restaurants in the UP all have cudighi, a local version of an Italian sausage sandwich made with pork sausage seasoned with wine, cinnamon, and garlic but with no fennel, a typical Italian sausage ingredient, cooked in patties instead of links, then placed on a roll with marinara, mozzarella, and sometimes peppers and onions. The Upper Peninsula of Michigan might as well be its own state culturally, and this sandwich proves it. The cinnamon is the unexpected twist that makes you pause mid-bite and wonder what you’re tasting. It’s simultaneously familiar and completely foreign, the kind of recipe that makes sense when you remember Michigan’s complex immigrant history. You won’t find this south of the Mackinac Bridge, let alone anywhere else in America.
