Carl's Jr. is set to release an All-Natural Burger said to feature an all-natural patty made with free-range beef. Apparently, the burger doesn't contain any added hormones, antibiotics or steroids, which is pretty big news for a fast food chain.

Because a beef patty alone doesn't make a burger, the All-Natural Burger is topped off with red onions, vine-ripened tomatoes, lettuce, pickles, ketchup, mustard and mayo and a slice of natural cheddar cheese. It's served between a freshly-baked bun.

The fast food chain stated that the burger was created as a way to meet a growing demand for "cleaner," more natural food. They mention this applies particularly to the Millennial crowd. The burger is claimed to be the first all-natural beef option presented by a major fast food company.

Carl's All-Natural Burger will be available beginning Wednesday, Dec. 17. It will be sold as a single burger for $4.69 and a double burger for $6.99, as well as a combo option. The burger will be available at all participating Carl's Jr. locations. Also, guests can get $1 off this new burger by presenting a coupon upon ordering.

Be careful, Carl's. With these new fresh buns and all-natural burger patties, you're treading dangerously into QSR territory.
