Pho is one of Vietnam’s most beloved dishes, known for its aromatic broth, tender meats, fresh herbs, and rice noodles. It’s a staple in Vietnamese cuisine and has gained global popularity for its comforting and nourishing qualities. However, for those with gluten sensitivities, celiac disease, or a preference for gluten-free foods, a crucial question arises: Is pho gluten-free?
While traditional pho may seem safe due to its rice-based noodles, hidden sources of gluten can sometimes make this dish unsafe for people with gluten intolerance. From broths thickened with wheat-based additives to sauces containing gluten, there are several factors to consider before indulging in a bowl of pho.
In this guide, we’ll break down whether pho is truly gluten-free, what ingredients to watch out for, and how to enjoy this delicious dish without any risks.

Understanding Pho
What is Pho?
Pho (pronounced “fuh”) is a Vietnamese noodle soup that typically consists of a flavorful broth, rice noodles, protein (such as beef or chicken), and a variety of fresh garnishes like bean sprouts, lime, basil, and chili peppers. It is often served with condiments such as hoisin sauce and sriracha.
This dish has a deep cultural significance in Vietnam, originating in the early 20th century. Over time, it has evolved with regional variations and has become a global favorite.
Common Ingredients in Pho
A traditional bowl of pho usually includes:
- Rice noodles (Bánh phở) – Made from rice flour and water, these are naturally gluten-free.
- Broth – Prepared by simmering beef or chicken bones with spices like star anise, cinnamon, and ginger.
- Protein – Common options include beef (Pho Bo), chicken (Pho Ga), or tofu for vegetarian versions.
- Herbs and vegetables – Basil, cilantro, green onions, and bean sprouts.
- Condiments – Hoisin sauce, fish sauce, soy sauce, sriracha, and chili paste (some of these may contain gluten).
While these ingredients seem naturally gluten-free, certain hidden elements may introduce gluten into the dish.
Gluten and Its Presence in Foods
What is Gluten?
Gluten is a group of proteins found in wheat, barley, and rye. It provides elasticity and chewiness to baked goods and acts as a thickening agent in various sauces and processed foods. For individuals with celiac disease or gluten sensitivity, consuming gluten can cause severe health issues, including digestive discomfort, inflammation, and long-term complications.
Foods That Contain Gluten
Some common sources of gluten include:
- Wheat-based products – Bread, pasta, pastries, and cereals.
- Barley and rye – Found in malt, beer, and some processed foods.
- Thickened soups and sauces – Many restaurant soups use flour as a thickener.
- Soy sauce and hoisin sauce – Both are commonly used in Asian cooking and often contain wheat.
Since gluten is found in unexpected places, it’s crucial to examine pho ingredients closely.
Is Traditional Pho Gluten-Free?
Gluten in Rice Noodles
Rice noodles, which are the primary carbohydrate in pho, are naturally gluten-free as they are made from rice flour and water. However, some store-bought brands may contain additives or be processed in facilities that handle gluten, leading to cross-contamination. Always check the packaging for a certified gluten-free label.
Is Pho Gluten-Free?
The broth is where things can get tricky. While a traditional pho broth is made by simmering bones, water, and spices, some restaurants or packaged versions may:
- Use seasoning mixes containing wheat-based thickeners.
- Add pre-made soup bases that may contain soy sauce or hydrolyzed wheat protein.
- Use bouillon cubes that sometimes contain gluten.
Gluten in Seasonings & Condiments
Pho is often served with a variety of condiments, some of which may contain gluten, including:
- Soy sauce – Traditional soy sauce contains wheat, though tamari is a gluten-free alternative.
- Hoisin sauce – Many brands contain wheat flour or malt vinegar.
- Fish sauce – Usually gluten-free, but some brands may have additives.
- Sriracha and chili pastes – Some brands use wheat-derived stabilizers.
To ensure your pho remains gluten-free, always verify ingredient labels or opt for homemade versions.
Hidden Sources of Gluten in Pho
Even if the main ingredients in pho seem gluten-free, there are several hidden sources of gluten that can make this dish unsafe for individuals with gluten sensitivities or celiac disease.
Soy Sauce & Hoisin Sauce
One of the biggest culprits of hidden gluten in pho is the condiments used for seasoning. While many people add soy sauce or hoisin sauce to enhance the flavor of their pho, both of these sauces often contain wheat.
- Soy sauce – Traditional soy sauce is made from fermented soybeans and wheat. However, tamari is a gluten-free alternative that can be used instead.
- Hoisin sauce – A sweet, thick sauce often served with pho, hoisin typically contains wheat flour or barley malt, making it unsafe for gluten-free diets. Fortunately, gluten-free hoisin sauce is available in some specialty stores.
To keep your pho gluten-free, always ask about the ingredients in these sauces or opt for certified gluten-free versions.
Cross-Contamination Risks
Cross-contamination is another issue when ordering pho at a restaurant or purchasing pre-packaged ingredients. Some common risks include:
- Shared cooking equipment – Restaurants may use the same pots, ladles, and strainers for different soups that contain gluten.
- Pre-packaged soup bases – Some pho broths use commercially made soup bases, which may contain gluten-based preservatives or thickeners.
- Thickened broths – Some chefs add flour or starches (like wheat-based roux) to make the broth richer.
If you’re highly sensitive to gluten, always check with the restaurant or food manufacturer before consuming pho.
