Are Chinese Sauces Keto-Friendly? What to Avoid and Embrace

6 min read

Over 70% of sauces at Americanized Chinese restaurants are thickened with carb-heavy cornstarch and sweetened with sugar. So, are Chinese sauces keto-friendly? The vast majority are not, as they contain hidden sugars and starches that can quickly disrupt ketosis.

Quick Summary

Many traditional and commercial Chinese sauces are not suitable for a ketogenic diet due to high sugar and starch content. Learn to identify and avoid sauces like hoisin and sweet and sour, opt for alternatives like soy sauce or fish sauce in moderation, or create your own low-carb versions at home.

Key Points

  • Avoid high-carb sauces: Steer clear of thick, sweet, or sticky Chinese sauces like hoisin, sweet and sour, and brown sauce, as they are typically loaded with sugar and starches.

  • Choose keto-friendly alternatives: Use low-carb options like standard soy sauce, tamari, fish sauce, or coconut aminos to add savory flavor to dishes.

  • Make your own sauces: The most reliable way to ensure a sauce is keto-friendly is to make it at home using approved sweeteners and thickeners like xanthan gum.

  • Order sauces on the side: At restaurants, always ask for sauces to be served separately to control the portion size and avoid hidden carbs.

  • Stick to simple preparations: When eating out, opt for steamed or roasted dishes with minimal, clear sauce, and ask about added ingredients like cornstarch.

  • Read ingredient labels: If buying bottled sauces, carefully check the nutrition label for added sugars and starches, even in products that seem simple.

Navigating High-Carb Chinese Sauces

For those following a ketogenic diet, the bold and flavorful sauces that define Chinese cuisine often pose the biggest challenge. The sweet, tangy, and thick consistency of many popular sauces is achieved by adding high-carb ingredients like sugar, honey, and cornstarch. Understanding which sauces to avoid is the first step toward making informed, keto-friendly choices.

The Common Offenders

  • Sweet and Sour Sauce: A classic example, this sauce is loaded with sugar, often containing anywhere from 7 to 30 grams of carbs per serving. Its signature flavor comes directly from high-sugar ingredients.
  • Hoisin Sauce: Often called Chinese barbecue sauce, hoisin is a thick, sweet condiment made with fermented soybeans, sugar, and various starches. Just two tablespoons can contain 20 or more net carbs.
  • Oyster Sauce: While the carb content can vary by brand, most store-bought oyster sauces contain added sugar and cornstarch to achieve their characteristic thick, dark texture. Some keto-specific versions are available, but traditional recipes are not suitable.
  • Brown Sauce: A staple in many American-Chinese dishes, brown sauce gets its velvety texture from cornstarch and its flavor from added sugar. It is not keto-friendly.
  • General Tso's and Orange Chicken Sauce: The glossy, sticky glaze on these popular dishes is a clear sign of high sugar and starch content. They should be avoided entirely on a keto diet.

Making Smarter Choices: Keto-Friendly Sauces and Alternatives

Fortunately, it's possible to enjoy the complex flavors of Chinese food without compromising your diet. The key is to be selective when dining out and proactive when cooking at home.

  • Soy Sauce and Tamari: Standard soy sauce is generally low in net carbs, with a typical tablespoon containing less than one gram. Tamari is a great gluten-free alternative that is also very low-carb. However, be cautious with darker or sweetened soy sauces, which can have higher carb counts.
  • Fish Sauce: A staple in Southeast Asian cuisine, fish sauce offers a potent umami flavor and is naturally low in carbohydrates. It can be a great, flavorful addition to many keto-friendly Asian dishes.
  • Coconut Aminos: For those avoiding soy or looking for a gluten-free option, coconut aminos is an excellent substitute for soy sauce. Made from fermented coconut sap, it has a slightly sweeter, milder flavor but is a common keto staple. Note that some brands may be higher in carbs than soy sauce, so always check the label.
  • Homemade Sauces: The best way to control your intake is to make your own sauces. By using keto-approved sweeteners like monk fruit or erythritol and thickeners like xanthan gum, you can recreate your favorite Chinese flavors without the carbs.

Tips for Ordering and Cooking Keto-Friendly Chinese Food

  • Order Sauce on the Side: When dining out, this is the most crucial step. Request that sauces be served separately, so you can use them sparingly or not at all.
  • Choose Wisely: Opt for clear, broth-based sauces over thick, opaque ones. A sauce that is gravy-like or very glossy is almost certainly thickened with starch.
  • Stick to Steamed or Roasted Dishes: Steamed fish and vegetables are safe bets. Roasted duck or crispy-skin pork belly can also be keto-friendly choices, but always ask about the preparation.
  • Ask Questions: Don't hesitate to ask your server about ingredients. Inquire if dishes are made with added sugar, cornstarch, or other high-carb thickeners.
  • Build Your Own: At a buffet, create your own stir-fry with meat, low-carb vegetables, and a simple seasoning of soy sauce and oil.
  • Use Alternatives: When cooking at home, replace high-carb soy sauces with tamari or coconut aminos and thicken sauces with xanthan gum instead of cornstarch.

Simple Homemade Keto Brown Sauce Recipe

Making your own versatile brown sauce is straightforward and ensures it's 100% keto. The primary ingredients are beef broth, soy sauce (or tamari), and a keto-friendly sweetener, with xanthan gum used as a thickener.

Ingredients:

  • 1/2 cup beef broth
  • 1/4 cup low-carb soy sauce or tamari
  • 1 tbsp fish sauce
  • 1/4 cup Lakanto brown sweetener (or similar keto sweetener)
  • 1 tsp sesame oil
  • 1/4 tsp xanthan gum

Instructions:

  1. In a small saucepan, whisk together the beef broth, soy sauce, fish sauce, and sweetener over medium heat.
  2. Bring the mixture to a boil, then reduce the heat to a simmer.
  3. Slowly sprinkle in the xanthan gum while continuously whisking to prevent clumping. The sauce will thicken almost instantly.
  4. Add the sesame oil and whisk to combine. Let it cool slightly before serving.

Conclusion: Savor Flavor, Skip the Carbs

In conclusion, while the most popular, thick, and sweet Chinese sauces are decidedly not keto-friendly due to their reliance on sugar and starch, there is plenty of room for maneuver. By understanding which sauces to avoid and embracing low-carb alternatives like tamari, fish sauce, and especially homemade versions, you can continue to enjoy the vibrant and savory flavors of Chinese cuisine. The key is to be mindful of hidden carbs and take control of your condiments, whether you are dining out or cooking at home.

Key Takeaways

  • Sweet and thick sauces are typically not keto: Popular sauces like hoisin, sweet and sour, and General Tso's are loaded with sugar and starch and should be avoided.
  • Soy sauce is generally keto-friendly: Standard soy sauce is low-carb, but check for added sugars in dark or sweet varieties. Tamari is a gluten-free option.
  • Coconut aminos is a good alternative: For those avoiding soy, coconut aminos provides a low-carb, soy-free flavor similar to soy sauce.
  • Order sauces on the side: A simple request at restaurants is crucial to controlling your carb intake.
  • DIY sauces are the safest bet: Making your own keto sauces at home with low-carb sweeteners and thickeners gives you full control.
