Let’s get geeky for a second. The tortilla is the real difference. Flautas use corn tortillas, which are stiffer and fry up crispy. Chimichangas use flour tortillas, which are softer and puff up like a golden pillow. A flauta is a whisper; a chimichanga is a roar.
Also, chimichangas are usually topped with everything—cheese sauce, salsa, guacamole, sour cream—like a parade on a plate. Flautas are more minimalist. They’re the “I woke up like this” friend, while the chimichanga is the one who wears four layers of makeup and looks fabulous.
One more thing: a flauta is rolled tight, so it stays slender. A chimichanga is usually folded like a burrito before frying, which means it’s thicker. It’s the difference between a rolled-up yoga mat and a stuffed duffel bag.
