Add mashed potatoes to anything...
You know what makes every single chicken sandwich on the planet better? Mashed potatoes. They're like two peas in a pod, but contain much more chicken and fewer peas. And even though KFC doesn't advertise it, you can ask to add mashed potatoes to any sandwich. Now, I've definitely been told "no" before, but often they'll grant you your wish.
... but never, ever, ever, ever, ever order them on their own (or any other side!)
When you go to KFC, do not get hypnotized by its delicious sides and just order them with every meal. Make sure to only order mac & cheese and mashed potatoes as part of a $5 Fill Up. Ordering everything as a side is a rookie mistake, like trying to do a Friday New York Times crossword puzzle with a pen. Yeah, we can like KFC and still be highbrow!
Here's some boring math: One side is usually around $2.50 on its own (depending on where you live). But for around $5 total, you can get that same side with a drink, a cookie, and a main item! And how do you do that? You order a meal called a $5 Fill Up, of course!
You can also add bacon to anything
Bacon is a staple menu item at basically every fast-food chain. KFC has it too, despite not having a ton of bacon-filled dishes. But it's there! Next time you go, add bacon to whatever you'd like, whether it be a Famous Bowl or a Chicken Littles sandwich. Congrats on making your meal at least 45% better, according to a fact we just invented that we definitely can't back up with empirical evidence.
You can order livers and gizzards at KFC
Yes, you can order those tasty (mostly unloved) parts of the chicken deep-fried at KFC. Here's the catch: The offal are not available in every region. In the regions where they're available, they're on the menu and beloved. But not elsewhere. You'd think they'd be available in all the Southern states, as fried gizzards are a traditional Southern food, but that's not true either! We spoke to a store in Tennessee that had 'em, but one in Mississippi didn't! The only way to find out is to ask. And once you do, maybe you'll soon be enjoying some deep-fried chicken parts.
Bring back the Double Down (but just for you personally)
Back in 2014, everyone and their momma was eating the KFC Double Down, which is two fried chicken filets instead of bread, plus bacon, two different kinds of cheese, and a drizzle of Colonel's Special Sauce. It's no longer on KFC menus. But that doesn't mean you can't order it! KFC still has all the ingredients other than the Colonel's sauce, which is a mayo- and ketchup-based condiment. Note that this is different from the chain's Finger Lickin' Good Sauce, which is more of a honey mustard-ish condiment. And most locations still have the sammy in their system, so they can ring you up no problem. Order it and enjoy a (deep-fried, cheese-covered) slice of American fast-food history!
