Percentages are the share of the FDA Daily Value for adults and children 4 and over, worked out from Sonic’s published amounts (how % Daily Value works). A dash means Sonic does not publish that value for this size. Not published for this item: added sugars.
Using the FDA’s rule of thumb that 5% of the Daily Value or less per serving is low and 20% or more is high, the Mini size is high in saturated fat (55%) and carbohydrate (20%) and is low in dietary fiber. Add it up with other items in the Sonic nutrition calculator.

Sonic relies on its suppliers for allergen information and shares cooking and preparation areas, so it says it cannot rule out cross-contact or promise that any item is free of an allergen, and no item is certified gluten-free, vegetarian or vegan. Blended drinks and frozen desserts share tools, fried foods share fryers, and grilled items share the grill. Buns, Texas Toast, eggs, grilled onions and grilled peppers are cooked with a bun oil that contains soy. Some breads come from local bakeries, so ingredients and allergens such as sesame can differ by restaurant. Tell your carhop about any food allergy before ordering. Items marked as fried carry a risk of cross-contact with all allergens.
