Vegan Guide to Sonic Drive-In: Best Menu Options, Swaps, and More

With over 3,500 locations across the United States, Sonic Drive-In has major staying power. The menu includes many fast-food favorites—burgers, patty melts, slushes, shakes, and much more.

While Sonic isn't the vegan mecca we had hoped for, plant-based customers aren't completely out of luck. Here are all of the vegan menu items you can order at Sonic.

Our Top Picks

These vegan options don't quite make a meal, but they can still quell your hunger in a pinch. Keep in mind: All fried options, even if they start off as vegan, may be cooked in the same oil used to cook animal products. If you are concerned, ask your Sonic location about cross-contamination.

Onion Rings

Completely vegan onion rings are hard to come by, and we're thrilled to find them at Sonic. You can dip these snacks in your choice of ketchup, mustard, and BBQ sauce.

French Fries

Fries with the skins on get the nod in our book. At Sonic, you have the option of adding toppings to your fries. Make sure to choose veggies only, like diced onions or jalapeños. And don't forget your vegan dip.

Custom Slushes

In addition to Sonic's expansive slushie menu, you can order a custom slushie with additional vegan syrups. From blackberry tea to blue coconut, there are plenty of plant-based flavor combinations.
