Ultimate Guide to Sides That Deserve Main Character Energy

Burgers and tacos might headline the fast food menu, but let’s be honest—the sides are often the real stars. Whether you’re craving something crispy, cheesy, creamy, or spicy, the best sides bring way more flavor (and fun) than you’d expect from a supporting role.

Here’s the ultimate lineup of fast food sides that steal the show—and keep diners coming back for more.

1. Arby’s Curly Fries
   Perfectly seasoned and springy with every bite, Arby’s curly fries are a cult classic for a reason. That signature spiral shape holds the seasoning better than your average fry, making every bite bold.
2. Chick-fil-A Waffle Fries
   Crispy on the outside and fluffy on the inside, Chick-fil-A’s waffle fries are iconic. Dip them in Chick-fil-A sauce or Polynesian sauce and they’ll instantly upgrade your meal.
3. Popeyes Cajun Fries
   Lightly spiced and satisfyingly crunchy, these fries pack more heat and flavor than their golden competitors. They’re especially good with a side of ranch or Blackened Ranch.
4. Taco Bell Cheesy Fiesta Potatoes
   Taco Bell’s side game is underrated, and these creamy, cheesy, seasoned potatoes deserve more attention. Topped with sour cream and nacho cheese, they’re like loaded fries with a Tex-Mex twist.
5. KFC Mac & Cheese
   Creamy, gooey, and unapologetically rich, KFC’s mac & cheese is the comfort food side you didn’t know you needed alongside fried chicken. It’s heavy, but worth every bite.
6. Sonic Mozzarella Sticks
   Crunchy, melty, and made for marinara dunking, Sonic’s mozzarella sticks hold their own as a standalone snack. They’re crispy on the outside without being greasy—and don’t collapse in your hand.
7. White Castle Onion Rings
   Sweet, savory, and satisfyingly crunchy, White Castle’s onion rings are one of the better-kept secrets in fast food. They’re not as common as fries, but they hit harder when done right.
8. Culver’s Wisconsin Cheese Curds
   These are more than a side—they’re an experience. Lightly battered and full of melty cheese, Culver’s curds have become legendary across the Midwest and beyond. They even crackle when you bite into them.
9. Checkers/Rally’s Fully Loaded Fries
   These are basically fast food poutine: crispy fries topped with cheese, ranch, and bacon. You could eat them with a spoon—and probably should.
10. McDonald’s Apple Slices
    Yes, really. If you’re going for a lighter meal or just need something crisp and fresh on the side, apple slices from McDonald’s are a solid pick—especially when paired with a kid’s cheeseburger.
