Best food options
If you are looking for a Sonic nutrition guide, this printable nutrition guide is a PDF from their website. Unfortunately, it isn't user-friendly at all. The font is really small, and you have to do the math to figure out the net carbs.
That's why I created this guide for keto diet options at Sonic that you can refer to instead!
The easiest way to navigate eating low carb at Sonic is to stick to ordering keto drinks and meat. So, let's look at both categories a little closer.

How to order
There are a few simple rules to remember when you are trying to eat keto at Sonic.
Following these rules will help you find the most keto-friendly options at Sonic without stressing out even a little bit.
Here are some really simple rules to follow to stay on track:
1. Avoid the french fries and tots.
Unfortunately, all those tasty sides have too many carbs to be keto-friendly. Just like you naturally avoid potatoes on a low-carb diet, avoid anything breaded at Sonic.
This also includes those mozzarella sticks. They haven't made a keto-friendly version of them yet.
Basically, avoid all the sides to stay keto at Sonic. They don't have many low-carb options in the snack or sides portion of the menu.
2. Decline crispy sandwiches.
Any type of crispy sandwich means that it was breaded. Since breading has way too many carbs to keep you within your macros, you should always choose grilled meats if you can. That means don't order a bunless crispy chicken sandwich from Sonic Drive-In.
The safest option will always be:
- Burger patties
- Grilled chicken
- Scrambled eggs
Ordering a Supersonic Bacon Double Cheeseburger without the bun is another popular choice!
Also, don't skip out on the chili cheese coney - just tell them no bun.
3. Order sugar-free drinks.
Play it safe and just order diet or sugar-free drinks. This includes things like diet sodas and unsweetened tea or coffee.
When you order your drink, remember to tell them not to add any sweetener to your tea or coffee. (Some employees might add sugar to it without thinking.)
It's a lot safer to add the sugar substitute yourself. That way, you can control how sweet it is and whether it is real sugar or low-carb sweetener.
4. Choose low-carb add-ons.
There are a lot of different things you can add to your bunless burger or grilled chicken. Here are the low-carb options you can request at Sonic:
- Crispy Bacon
- American Cheese
- Grilled Onions
- Green Chiles
- Ranch Dressing
- Light Mayo
Here are a few answers to the most frequently asked questions about ordering keto food at Sonic! If you don't see your question in this list, please leave it in the comments.
No, the onion rings at Sonic are not keto-friendly. They are breaded with all-purpose flour, which has too many carbs to keep you within your macros.
Just remember to order unsweetened drinks and meats without the bread when you are eating at Sonic. Bunless burgers or sandwiches are a safe bet. If you see a salad on the menu, order it without any dressing.
Honestly, they don't have very many keto-friendly options. All of their slushes and shakes are packed with sugar. The best option is to order unsweetened tea or water.
You can also order a diet Cherry limeade - it only has 3g net carbs. Plus, there are just 1.9 grams net carbs in a diet strawberry limeade, so that is another fantastic option.
Yes, the Sonic chili is keto-friendly, but you have to watch how much of it you eat. There are 9 grams of net carbs in one bowl of chili. If you eat half of it and add cheese and jalapenos, you can enjoy this on the keto diet.
