White Castle Southwest Veggie Slider FAQs
Is the White Castle Southwest Veggie Slider vegan? ▼
No, the default White Castle Southwest Veggie Slider is vegetarian rather than strictly vegan because the Southwest Ranch sauce contains dairy buttermilk and egg yolks. However, both the Dr. Praeger's vegetable patty and the White Castle slider bun are 100% vegan—order the Veggie Slider without ranch sauce (or with Sweet Thai sauce, ketchup, or mustard) to make it completely vegan.
Who makes the White Castle Veggie Slider patty? ▼
Dr. Praeger's Sensible Foods manufactures the official vegetable patty used in White Castle Veggie Sliders. Each patty is blended from real diced carrots, zucchini, peas, spinach, broccoli, corn, red bell peppers, onions, and rolled oats without artificial preservatives or soy protein isolates.
Are White Castle Veggie Sliders cooked on a separate grill from beef? ▼
Yes, White Castle prepares Dr. Praeger's Veggie Sliders on a dedicated heating surface separate from beef and bacon griddles to minimize direct meat grease transfer. Because all stations operate inside the same kitchen, guests with severe medical food allergies should inform the cashier upon ordering.
What is the difference between the Veggie Slider and the Impossible Slider? ▼
The Veggie Slider ($2.19–$2.49, 150–190 calories, 5g–6g protein) uses a whole-vegetable Dr. Praeger's garden patty made from carrots, spinach, and peas, whereas the Impossible Slider ($2.29, 250 calories, 12g protein) uses a soy-and-heme plant-based burger patty engineered to replicate the taste and texture of seared ground beef.
Are White Castle slider buns vegan? ▼
Yes, White Castle signature 2×2-inch white slider buns are 100% vegan. Unlike many fast-food brioche buns, White Castle buns contain zero dairy, zero butter, zero eggs, zero honey, and plant-derived enzymes rather than animal L-cysteine.
