Fried; the allergen guide flags a risk of cross-contact with all allergens due to the cooking method.

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.
