White Castle calories: the best order for every goal
White Castle publishes calories, fat, sodium, carbohydrate, fiber, sugar and protein for its full menu on its website, and the sliders are the whole story. One Original Slider is 140 calories, so a sack is really a running total: four is a light 560, ten is a heavy 1,400. The chicken rings and fish nibblers do the most protein for the calories. Every figure below comes from that published data.

The best White Castle order for every goal
Every figure below is calculated from White Castle’s own published per-ingredient nutrition. Portions and recipes change, so confirm against the live White Castle nutrition calculator before you order.
Goal

Cal
Protein
Highest protein
Chicken Rings (6 ct)18g of protein and just 12g of carbs for 320 calories, the best protein-per-calorie order on the menu and better than any single slider. For raw grams, a 20-count sack carries 58g at 1,050 calories. A Bacon Cheddar Slider packs 12g into 220 calories if you would rather stack sliders.

Lowest calorie (still filling)
Two Original SlidersEach Original Slider is 140 calories with 6g of protein, so two make a 280-calorie snack. A single Cheese Slider is 170 and a Chicken Ring Slider with cheese 200. Skip the large fry, since a small is already 330 calories on its own.

12g
Keto / low-carb
Chicken Rings (6 ct), no friesAt 12g of carbs the chicken rings are the lowest-carb real food on the menu, and they come without a bun. Sliders are mostly bun, so each Original is 15g of carbs. White Castle does not publish a no-bun slider figure, so we do not estimate one. Fish Nibblers are 28g in a small.

Vegan (best plant-based)
Southwest Veggie SliderWhite Castle's meat-free slider, 240 calories with 31g of carbs. It is a plant-based patty on the standard bun, not a certified vegan item, so check the allergens and ingredients guide for cheese, egg and cross-contact before ordering it as a vegan meal.
240
6g
Gluten-free
Check the allergens and ingredients guideWhite Castle's buns and breaded items contain wheat, and fried items are cooked in common oil, so cross-contact is likely. White Castle publishes an allergens and ingredients guide, and nothing on the standard menu is certified gluten-free. Confirm any item with the guide and staff before ordering.

Frequently asked
How many calories are in a White Castle slider?
Per White Castle's published data, The Original Slider is 140 calories with 6g of protein, a Cheese Slider 170 and a Double Cheese 300. Because they are small, the count is really the calorie dial: four Original Sliders are 560 calories and ten are 1,400.
What is the healthiest thing to order at White Castle?
The Chicken Rings. A 6-count is 320 calories with 18g of protein and only 12g of carbs, and it comes without a bun. Pair a small order with one or two plain sliders instead of a large fry, since a small fry is 330 calories on its own.
How much protein is in White Castle chicken rings?
Per the published guide, a 6-count is 18g, a 9-count 26g and a 20-count sack 58g, at 320, 470 and 1,050 calories. That makes the chicken rings the best protein-per-calorie order on the menu, ahead of the sliders.
Does White Castle have low-carb options?
Somewhat. The chicken rings are the lowest-carb real food at 12g and come bun-free. Sliders are mostly bun, so each Original is 15g of carbs, and White Castle does not publish a no-bun slider number. Fish Nibblers are 28g in a small.
