The Carbohydrate Breakdown of a Pastrami Reuben
To understand the total carbohydrate count of a pastrami reuben, it is essential to analyze each component individually. The classic construction of this sandwich includes rye bread, pastrami, Swiss cheese, sauerkraut, and a creamy dressing like Russian or Thousand Island. The varying amounts and preparation methods of each ingredient directly affect the total carbohydrate and net carbohydrate count.
The Primary Contributor: Rye Bread
The two slices of rye bread typically used in a reuben are the single largest source of carbohydrates. Standard rye bread contains approximately 15 to 20 grams of carbs per slice, with a decent amount of fiber. A medium-sized sandwich using two slices of dark rye could easily start with around 30-40 grams of total carbohydrates just from the bread. Substitutions like marbled rye or pumpernickel will have similar carb levels, while plain white bread would be different. For those seeking lower-carb alternatives, keto-friendly bread or the use of "chaffles" (cheese and egg waffles) can dramatically reduce this number.
The Protein Core: Pastrami
Pastrami, the star of the show, is a cured and seasoned beef product. According to nutritional data, pastrami contains very few carbohydrates. A serving of pastrami (e.g., 3 ounces) typically contributes less than 1 gram of carbs, making it a low-carb, high-protein ingredient. The primary nutritional factors to consider with pastrami are its high sodium and fat content, not its carbs.
The Tangy Toppings: Sauerkraut and Swiss Cheese
- Sauerkraut: This fermented cabbage is a surprisingly low-carb ingredient. While raw cabbage has some carbohydrates, the fermentation process consumes much of the sugar, resulting in a very low net carb count. A cup of canned sauerkraut might have around 6 grams of total carbs but 4 grams of fiber, leaving only 2 grams of net carbs. It also provides beneficial probiotics for gut health. The key is to drain it well to avoid a soggy sandwich and minimize liquid content. For low-carb diets, this is a very compatible ingredient.
- Swiss Cheese: Swiss cheese adds a creamy, nutty flavor and contributes very few carbohydrates. An ounce of full-fat Swiss cheese contains less than 2 grams of carbohydrates and is a good source of protein and calcium. The carb count for cheese is typically negligible in the context of the entire sandwich.
The Creamy Finish: Russian or Thousand Island Dressing
The dressing is another variable that can impact the total carb count. A tablespoon of a standard Russian or Thousand Island dressing can contain around 3 to 5 grams of total carbohydrates, largely from added sugar. Since many reubens are made with a generous amount of dressing, this can add up quickly. Opting for a low-calorie or sugar-free version, or making a homemade dressing with sugar-free ketchup and mayonnaise, can help reduce the carb load.
Nutritional Comparison of Reuben Components
To illustrate the carb contribution of each ingredient, the following table provides an estimated breakdown for a standard-sized reuben.
| Component | Estimated Total Carbs (g) | Estimated Net Carbs (g) | 
|---|---|---|
| 2 Slices Rye Bread | 30 - 40 | 25 - 30 | 
| 3 oz Pastrami | < 1 | < 1 | 
| 1/2 Cup Sauerkraut | 3 - 4 | 1 - 2 | 
| 2 oz Swiss Cheese | 2 - 3 | 2 - 3 | 
| 2 Tbsp Russian Dressing | 8 - 10 | 7 - 9 | 
| Total Estimate | 44 - 58 | 35 - 45 | 
Note: Estimates vary based on portion sizes, specific brands, and preparation. This table provides a general guideline.
Customizing Your Reuben for a Lower Carb Intake
For those watching their carb intake, there are several simple modifications to enjoy the flavors of a pastrami reuben without the high carb count. One key strategy is to use alternatives to traditional rye bread. Some keto-friendly options include low-carb bread, cloud bread, or using large lettuce wraps to replace the bread entirely. Alternatively, the popular low-carb “chaffle” can be a fantastic, flavorful bread substitute. Another option is an open-faced reuben, using just one slice of bread or a base of roasted mushrooms. Controlling the portion of dressing or choosing a sugar-free version is also a simple way to shave off extra carbs. Many low-carb recipes suggest homemade versions of the dressing using mayonnaise, sugar-free ketchup, and spices. The pastrami and Swiss cheese are already very low in carbohydrates, and sauerkraut, with its high fiber content, is a beneficial component to keep.
Additional Low-Carb Recipe Ideas
- Reuben Salad: Serve the traditional reuben ingredients over a bed of greens instead of bread. Mix pastrami, shredded Swiss, and sauerkraut with a low-carb dressing. This turns a sandwich into a crisp, satisfying salad.
- Reuben Bowl: Layer pastrami, drained sauerkraut, and melted Swiss cheese in a bowl. Top with a low-carb dressing for a hot, deconstructed version of the sandwich.
- Mini Reuben Bites: Create bite-sized appetizers by layering pastrami, a dollop of sauerkraut, and a small piece of Swiss cheese on a pickle slice or a small low-carb cracker.
Conclusion
A pastrami reuben's carbohydrate content is primarily influenced by the type and quantity of rye bread used. While other ingredients like the dressing contribute to the overall carb count, they are less significant. For those on a carb-conscious diet, simple substitutions such as using low-carb bread or serving the ingredients in a salad or bowl can significantly reduce the total and net carbohydrate load, allowing for a satisfying meal without compromising dietary goals. Careful portion control and smart ingredient choices are key to managing the carb count of this deli classic.

Additional Considerations for Low-Carb Diets
Beyond just the carbs, those on strict dietary plans, such as the ketogenic diet, should also be mindful of the overall fat and protein macros. The pastrami itself is very high in sodium due to the curing process, which is another factor to consider for overall health, especially for those monitoring blood pressure. While a classic reuben is high in carbs, the customizable nature of its components makes it a flexible dish for many dietary approaches. The probiotic benefits from the sauerkraut, for example, can be enjoyed whether or not you choose to include the high-carb bread.
