Trying to keep your meals exciting on a gluten-free diet can sometimes feel like a full-time job. Because so many traditional Asian sauces rely on hidden wheat, "Is kimchi gluten-free?" is one of the most frequent questions we hear. The good news is that you don't have to give up this flavor-packed staple; you just need to know what to look for.
The short answer? Most authentic kimchi is naturally gluten-free, but it all comes down to the specific thickener or sauce used during the seasoning process. At Mother-in-Law’s, we keep things transparent and traditional: all of our kimchi products are 100% gluten-free. Understanding the recipe gives you the peace of mind to make kimchi a worry-free part of your gluten-free rotation.
Is Traditional Kimchi Gluten-Free?
In its simplest form, kimchi is a mix of vegetables, chili pepper, garlic, ginger, and salt. Because it is one of the most popular gluten-free fermented foods, it’s a go-to for adding a massive flavor boost to your meals without relying on wheat-based condiments.
However, "traditional" can mean a lot of things. According to the Celiac Disease Foundation, gluten can often hide in thickeners or sauces used in processed foods. In the world of kimchi, some recipes use a small amount of flour paste to help the chili seasoning stick to the cabbage, while others might use soy sauces that contain wheat.
Ingredients to Watch Out For
When you’re scanning a label or eating out, there are three main culprits that can sneak gluten into a batch:
- Wheat Flour Paste: Many recipes use a "porridge" made of water and flour to create that thick coating on the vegetables. While rice flour (which is gluten-free) is the traditional choice, some commercial brands swap it for wheat flour.
- Soy Sauce: Standard soy sauce is usually brewed with wheat. If a kimchi recipe uses soy sauce for an extra umami kick instead of sea salt or fish sauce, it isn't gluten-free unless it specifically uses Tamari.
- Malt Syrup: This is sometimes used in kimchi recipes as a sweetener. Malt is derived from barley, meaning it definitely contains gluten.

How to Choose Gluten-Free Kimchi
The easiest way to make sure your jar is safe is to look for brands that prioritize clean, traditional ingredients. Here is how to pick the right one:
-
Check for Rice Flour: Look for "glutinous rice flour" or "sweet rice flour." Despite the confusing name, glutinous rice is actually 100% gluten-free. The name simply refers to the "glue-like" sticky texture of the rice.
-
Verify the Umami Source: Authentic kimchi usually gets its savory depth from sea salt, salted shrimp, or fish sauce.
-
Trust the Label: At Mother-in-Law's, we use traditional methods that naturally exclude gluten, so you can snack and cook with total peace of mind. Our authentic House Napa Cabbage Kimchi uses a traditional paste made with rice flour instead of wheat, and gets its deep umami from anchovy sauce, salted shrimp, and beef stock.
