Eating in Taiwan with a Food Allergy

Does Taiwanese food contain peanuts?

Short answer: yes, frequently. Peanuts and peanut oil are everywhere in Taiwanese cooking — present in dishes you would never suspect, and standard in many sauces and marinades. Severe peanut allergies require constant vigilance here.

Common hidden sources

• Dan bing (蛋餅) wrappers and many breakfast crepes
• Ba-wan (肉圓) toppings and dipping sauces
• Scallion pancakes (蔥油餅), many fillings, and pancake batter
• Lu rou fan (滷肉飯) toppings — crushed peanuts are a common garnish
• Mixed sesame–peanut oils used to finish many cold dishes
• Hot-pot dipping sauces (沙茶醬 sa-cha sauce often contains peanut)

Night market risk

Stalls share woks, oil, and utensils. Even if a dish does not contain peanuts in the recipe, the same oil is often used for peanut-coated items earlier in the day. Vendors rarely speak English and allergen awareness at street level is low. For severe allergies, we strongly advise avoiding night-market street food.

Safer choices when eating out

Steamed white rice, plain stir-fried greens with garlic only, sashimi at reputable sushi restaurants, Japanese-style sets, and Western chain restaurants are the lowest-risk options. Always communicate the allergy clearly before ordering — a phrase card helps.

Gluten and wheat in Taiwan

Gluten is harder to avoid in Taiwan than rice-eating expectations suggest. Soy sauce is wheat-based, dumplings and noodles are everywhere, and many sauces are thickened with wheat flour. The good news: rice-based alternatives exist for almost every Taiwanese dish if you know what to ask for.

Standard Taiwanese soy sauce contains wheat. Tamari (gluten-free soy sauce) is sold at premium supermarkets but rarely used at restaurants — assume cross-contamination unless explicitly confirmed.

Where gluten hides

• All wheat noodles, dumplings (餃子), buns (包子), scallion pancakes, and many breakfast items
• Standard soy sauce, hoisin, oyster sauce, and most dipping sauces
• Many braised dishes (lu wei 滷味) — the master sauce contains soy
• Beer and many Taiwanese spirits

Naturally gluten-free Taiwanese staples

• Plain rice, congee (粥), and most rice-based dishes
• Steamed sweet potato (地瓜) and taro (芋頭) — common breakfast and side dishes
• Most grilled meats and seafood at Japanese restaurants
• Stinky tofu is fermented soybean — usually gluten-free, but check the sauce

For imported gluten-free products, the best stores in Taipei are Jason's Marketplace (multiple locations), City'super (Breeze Center, Xinyi), and the Mia C'bon chain. Most carry gluten-free soy sauce, pasta, snacks, and baking mixes.

Shellfish and other common allergens

Shellfish is woven into Taiwanese cooking in ways that are easy to miss. Oyster sauce is the most common hidden source — used in vegetable stir-fries, fried rice, and noodle dishes that look completely safe on the menu.

Shellfish, oyster sauce, and dashi

Oyster sauce appears in dishes you would never suspect, including vegetarian-looking stir-fries. Many Taiwanese breakfast and lunch shops use a dashi (柴魚高湯) base that contains bonito and sometimes shrimp. Hot-pot broths often include seafood stock even when the headline ingredient is meat.

Egg and dairy

Eggs are common but less hidden than in Western baking — most egg dishes are obviously eggs. Dairy is less common in Taiwanese cooking than in Western food, but milk powder is sometimes used in breakfast items, condensed milk in shaved ice, and butter in modern fusion menus.

Sesame

Sesame oil is a finishing ingredient in many traditional dishes — drizzled over soups, noodles, and cold appetisers. Tahini-style sesame paste is also common in cold noodle dishes and dressings.
