Vegetarian Options at Sonic: What to Order (and What to Skip)

Finding vegetarian options at fast-food places can feel like a scavenger hunt. Sonic Drive-In, with its burgers, hot dogs, and milkshakes, probably isn’t the first spot you’d think of for vegetarian food—but you might be surprised!

While Sonic isn’t exactly a vegetarian haven, they do have a handful of quick, affordable, and satisfying options. Whether you’ve been meat-free for years or you’re just cutting back, this guide will help you navigate their menu without feeling like you’re missing out.

A Quick Disclaimer: Not a Full Meal Solution: Fast food is for those instances where I’ve been running around and suddenly realize I’m STARVING!!! I usually pick a snack to hold me over wherever I am. Don’t expect to get full here. 

As such, I’m not choosing nutrition-specific options but to fill a growling belly. So, let’s see what our options are.

When it comes to vegetarian burgers, Sonic doesn’t have a lot to offer on the national menu. But I’ve seen mentions of veggie burgers being available at some locations, so it’s worth checking with your local Sonic to see if it’s an option.

One thing to note: the allergen guide lists eggs and milk in the veggie burger, so it’s not vegan-friendly.

As for hot dogs, there aren’t any vegetarian or vegan-friendly options, which is a bit of a letdown.

Sonic’s grilled cheese sandwich is made with Texas toast—simple, but honestly, a little bland. I’ve had it before, and it didn’t wow me.

If you’re up for a little experimenting, consider customizing it! Adding the zesty cheese sauce from the Spicy Steak and Bacon Grilled Cheese could give it a flavor boost. Diced tomatoes or onions would work well, too.

For something slightly more filling, there’s a grilled cheese kids’ meal that comes with applesauce, fries or tots, and a small drink. It’s definitely carb-heavy, but it’s nice to have a bit of variety.

Let’s be real—this is where most of us vegetarians will find the good stuff at Sonic.

Here’s what’s on the table: mozzarella sticks, groovy fries, tater tots (with or without cheese sauce), pickle fries, onion rings, soft pretzel twists, and Ched ‘R’ Pepper bites.

A quick heads-up for vegans: the onion rings aren’t vegan-friendly since they’re breaded with buttermilk, but the pretzel twists seem to be (just skip the cheese sauce).

The pretzel twists are a fun option for a quick snack, and who doesn’t love a side of tots or fries? Personally, I think the nostalgia factor of these fried goodies makes them hard to pass up!

Sonic’s breakfast menu has a few vegetarian-friendly choices if you’re willing to make a small tweak. Here’s what’s available:

• Breakfast Toaster: Fluffy eggs, melty cheese, and Texas toast. Just ask for no meat. Simple and satisfying!
• Breakfast Burrito: A tortilla wrapped around eggs and shredded cheese. Perfect for a grab-and-go breakfast—just skip the meat.
• SuperSonic Breakfast Burrito: This one has a little more flair with diced tomatoes, onions, tots, and jalapeños. Again, be sure to leave the meat out.
• French Toast Sticks: Sweet and nostalgic, these come with maple-flavored syrup. Not the most filling, but definitely a fun treat!

While none of these options are groundbreaking, they’re quick and easy to customize when you’re on the go. If you’re a fan of breakfast for dinner, these could also be a good choice later in the day!

Let’s be honest—Sonic’s drinks and ice creams are what they’re famous for, right? Thankfully, they’re all vegetarian-friendly, and there are even a few fun vegan options if you know what to look for.

For vegans, the slushes are the real stars. With 12 different flavors, there’s something for everyone. The Blue Coconut Slush and Mango Slush sound especially refreshing on a hot day, but you can’t go wrong with classics like the Grape Escape or Rainbow Slush.

As for the creamier treats, many of Flavorista Favorites aren’t vegan, but they’re perfect for vegetarians craving something indulgent.

One quick tip: Always double-check with the staff to confirm ingredients—menus can vary by location. But with Sonic’s creative drink menu, you’re bound to find a treat that hits the spot!

Sonic might not be the top choice for a well-rounded vegetarian meal, but when you’re in a pinch, it gets the job done. With a bit of creativity and a few customizations, you can find something to hold you over while satisfying those fast-food cravings.

Plus, let’s be honest—tater tots have a way of taking us back, and that nostalgia counts for something!
