Overview

French toast is a dish of bread slices soaked in a beaten egg mixture and fried until golden. It can be prepared as a sweet dish with milk, sugar, and cinnamon, or as a savory dish with salt and pepper. The dish is known by many names across cuisines and appears in variations worldwide.

Origin and history

The basic technique of soaking stale bread in egg and frying it appears in European cookbooks as early as the 4th century CE, in the Roman cookbook Apicius, which describes a dish called aliter dulcia (another sweet dish) where bread is soaked in milk and egg, fried, and served with honey [3]. The name “French toast” in English dates to the 17th century, though the dish has no specific origin in France; the French call it pain perdu (“lost bread”), referring to the use of stale bread that would otherwise be wasted [1]. Similar preparations exist across Europe, the Middle East, and the Americas, each adapting the technique to local breads and sweeteners.

Varieties and aliases

  • Pain perdu (France) — stale bread soaked in egg and milk, fried, often served with sugar or jam
  • Torrijas (Spain) — bread soaked in milk or wine, then egg, fried, and often soaked in honey or syrup; associated with Lent and Holy Week
  • Grenki (Russia) — savory or sweet fried bread, often made from baton (Soviet-era white loaf) [1]
  • Hong Kong-style French toast — two slices of white bread sandwiched with peanut butter, dipped in egg, deep-fried, and topped with butter and syrup [1]
  • Torrejas (Guatemala, El Salvador, other Central American countries) — bread soaked in egg, fried, then bathed in warm spiced panela syrup; a Lenten and Holy Week specialty [1]
  • Eggy bread (UK) — common name for the savory version
  • Arme ritter (Germany) — “poor knights,” bread soaked in egg and milk, fried, served with fruit or sugar

Culinary uses

French toast is most commonly a breakfast or brunch dish, served sweet with toppings such as maple syrup, butter, fresh fruit, powdered sugar, or whipped cream. Savory versions are fried with salt and pepper and served with ketchup, mayonnaise, or other condiments. The dish is a practical use for stale or day-old bread, which absorbs the egg mixture without becoming mushy. In many cultures, French toast is associated with religious holidays: torrijas and torrejas are traditional during Lent and Holy Week in Spain and Latin America, while pain perdu appears in French home cooking year-round.

Cross-cuisine context

French toast has a direct analogue in the torrejas of Guatemala and El Salvador, where the dish is a signature Lenten dessert. Salvadoran torrejas use day-old pan francés or pan dulce sliced thick, dipped in a beaten egg-yolk batter, fried, then bathed in warm panela syrup spiced with cinnamon, cloves, and allspice [1]. Guatemalan torrejas follow a similar method, with the bread soaked briefly in egg, fried golden, then submerged in warm spiced panela syrup [1]. Both are served during Semana Santa (Holy Week) and are distinct from the breakfast-style French toast common in the United States.

Hong Kong-style French toast (sai do si) is a cha chaan teng (tea house) staple: two slices of white bread sandwiching peanut butter, dipped in egg, deep-fried until golden, and topped with a square of butter and golden syrup [1]. This version is sweeter and richer than most Western French toast, and is served as a snack or tea-time item rather than breakfast.

In Russian cuisine, grenki are made from baton (a soft white loaf) and can be either savory (fried with salt, served with soup) or sweet (dipped in egg and milk, fried, served with jam or sour cream) [1]. The savory version has no widely recognized analogue in Mexican cuisine, where bread-based egg dishes like chilaquiles or huevos divorciados use tortillas rather than bread.

Notes for cooks

  • Stale or day-old bread works best; fresh bread can become too soggy. Thick slices hold up better than thin ones.
  • For sweet French toast, let the bread soak just long enough to absorb the egg mixture without falling apart. For savory versions, a quick dip is sufficient.
  • The dish can be made ahead and reheated in a toaster or oven, though freshly fried French toast has the best texture.
