The Simple Answer: Yes, But It's Complicated
Unlike aged hard cheeses, which are naturally very low in carbohydrates, the popular nacho cheese sauce is not a single, pure ingredient. It is a concoction of cheese, milk, and thickening agents. The cheese itself contributes very little in the way of carbohydrates, which primarily come from the milk sugar, lactose. The longer a cheese is aged, the less lactose it contains, reducing its carb count further. Nacho cheese sauce, however, includes additional ingredients that significantly increase its carb count. Many recipes and commercially produced versions rely on a roux—a mixture of butter and flour—to create the thick, smooth consistency that people love. Processed cheese products, like those found in cans or pumps, may also contain additional stabilizers and fillers that can contain carbs.
The Breakdown: Carbs in Homemade vs. Processed Nacho Cheese
The carb count in your nacho cheese will depend heavily on its origin. A homemade sauce using a traditional roux will have a moderate amount of carbs from the flour and milk. For instance, a basic cheese sauce recipe might contain around 9 grams of carbohydrates per serving. In contrast, a processed cheese food product can have a different nutritional profile due to its manufacturing process and added ingredients. While a specific brand might contain only a few grams of carbs per serving, others may have higher counts depending on the inclusion of starches or sugar. Always check the nutrition label, as the ingredients and ratios vary widely by brand. For those on a low-carb diet, there are keto-friendly homemade recipes that use alternative thickeners, such as xanthan gum, to achieve a similar texture without the added carbs from flour.
A Closer Look at the Ingredients that Add Carbs
- Flour (All-Purpose): A primary thickening agent in many traditional homemade cheese sauces, flour is a starch that is high in carbohydrates.
- Milk: The natural sugar lactose in milk contributes to the overall carb count of the sauce. The type of milk used (e.g., whole milk vs. skim) can slightly alter this, but not drastically.
- Processed Cheese Products: Some processed cheese, like American cheese, or cheese spreads, can contain added carbs from stabilizers and other food additives.
- Starches and Thickeners: Commercially made nacho cheese may use starches or emulsifiers to achieve its texture and stability, which adds to the carbohydrate content.
Nacho Cheese Carb Comparison: Processed vs. Homemade
To illustrate the difference, here is a comparison based on typical ingredients and available nutrition data. Note that these values are approximate and can vary by brand or recipe.
| Feature | Processed Nacho Cheese | Homemade Nacho Cheese (with roux) |
|---|---|---|
| Primary Thickener | Starches, emulsifiers | Flour (via a roux) |
| Carb Source | Additives, dairy sugars | Flour, dairy sugars |
| Typical Carbs (per 1/4 cup) | ~4-6 grams | ~4-9 grams |
| Best for Keto? | Often contains too many additives and fillers; not ideal. | Can be modified for keto by omitting flour and using different thickeners. |
| Flavor Profile | Often salty, and sometimes described as artificial. | Richer, more authentic cheese flavor, depending on the cheese used. |
Making Your Own Low-Carb Nacho Cheese
For those managing their carbohydrate intake, a homemade version offers far more control over the final product. By substituting flour with a keto-friendly thickener, you can create a delicious sauce without the extra carbs. A popular alternative is xanthan gum, which provides excellent thickening power in small quantities. Combining this with heavy cream and your favorite shredded cheeses, such as sharp cheddar or Monterey Jack, allows you to enjoy a flavorful sauce while keeping net carbs very low. This process is not only healthier but also results in a fresher, more robust flavor profile than many store-bought alternatives.

Conclusion
While natural cheese itself is generally low in carbs, the sauces that are typically served as nacho cheese contain added ingredients that increase the carbohydrate content. Whether you are following a low-carb diet or simply watching your intake, understanding the difference between homemade sauces made with a flour-based roux and highly processed cheese products is crucial. The key is to check labels, or better yet, make your own at home to control exactly what goes into your food and keep your nacho experience both delicious and diet-friendly.
