Greek cuisine is one of the most loved food traditions in the world, built on olive oil, fresh vegetables, grilled meats and centuries old family recipes. But behind those comforting flavours sit several ingredients that regularly cause problems for allergy sufferers. If you are planning to enjoy Greek food, whether on a trip to Greece or at a Greek restaurant closer to home, it helps to know exactly where these allergens tend to hide.
Sesame Is Everywhere, Not Just on Burger Buns
Sesame seeds appear far more often in Greek cooking than most people expect. You will find them scattered across koulouri (the ring shaped street bread), pressed into breadsticks, blended into tahini based dips, and baked into sweets such as halva. Even a simple bread basket placed on the table before you order can carry sesame, so it is always worth asking before you eat.
Tree Nuts Show Up in Sweets and Savoury Dishes Alike
Walnuts, almonds, pistachios and hazelnuts are the backbone of many Greek desserts. Baklava is the obvious example, layered with filo pastry, syrup and a nut filling that changes from bakery to bakery. Karydopita uses walnut, while amygdalota is made almost entirely from almond paste. Nuts are not confined to dessert either. Pine nuts often appear in stuffed vegetables and rice dishes, and walnuts sometimes flavour salad dressings and meze spreads.
Dairy Runs Through Almost Every Meal
Feta cheese, made from sheep or goat milk, defines the classic Greek salad and cannot be left out without changing the dish entirely. Beyond the salad bowl, dairy turns up in spanakopita, tiropita, tzatziki (a yogurt based dip), saganaki fried cheese and countless sauces. Anyone managing a dairy allergy should ask specifically about cheese, yogurt, butter and milk rather than trusting a dish that looks vegetable based at first glance.
Wheat and Gluten Hide Inside Pastry and Sauces
Filo pastry is the foundation of spanakopita, tiropita, baklava and galaktoboureko, and it is made purely from wheat flour. Bread also arrives automatically at most Greek tables, and pita accompanies gyros and souvlaki. Less obvious is wheat used as a thickener in slow cooked stews such as stifado, so a meat dish can carry gluten even when no bread is in sight.
Eggs and Seafood Deserve Attention Too
Eggs bind custard filled pastries and thicken the classic avgolemono sauce found in soups and lemon chicken dishes. Meanwhile, Greece’s long coastline means fish and shellfish are central to many menus. Taramosalata, a fish roe dip, is often placed on the table as a shared starter, so it is easy to eat without realising, and shared serving plates raise the risk of cross contact between fish and non fish dishes.
Eating Greek Food Safely
The good news is that being aware of these patterns makes eating out far easier. Always mention your allergy clearly when ordering, ask whether bread or dips are already on the table, and check whether a dish shares oil, trays or utensils with a known allergen. A kitchen that can answer these questions confidently is one you can trust.
