LENEXA, Kan. — The Signature Slinger, a mushroom-meat burger from Sonic, made its nationwide debut March 5, and two members of The Packer staff promptly headed out for a taste test.

Numerous establishments have tried using chopped mushrooms in burger patties, often in conjunction with The Blend initiative championed by the James Beard Foundation and the Mushroom Council, but Sonic is the first quick-service restaurant to roll out such an option.

Designer Amelia Freidline and staff writer Ashley Nickle tried the new burger on the day of its full-scale reveal. Check out the video for their reaction and the links below for more coverage of this growing trend.

I did a side-by-side between Sonic’s Signature Classic and Carl’s Jr’s new Double Slider. Both were begging for seasoning. I couldn’t believe how wet the Sonic burger was. And it wasn’t grease; it was watery like the lettuce and tomatoes were wet. They use the same veggies on their regular burgers, and I’ve never noticed it before. The CJr slider was noticeably better. It’s slider-sized as opposed to dollar burger-sized, but you get more, thicker, better-tasting meat, for $1.49 as opposed to $1.99 for Sonic’s sloppy mess. The one thing the slider really needed - besides seasoning - was lettuce. Just a few sprigs of baby spinach and arugula would make a huge difference.
