A strata is essentially a baked bread and egg casserole. Cubed bread is layered with fillings and soaked in a custard mixture. After resting—preferably overnight—the bread absorbs the liquid completely. When baked, the edges become lightly golden while the centre stays tender and soft.
Day-old brioche or French bread, cubed (1 large loaf, about 450 g)
Large eggs (8)
Whole milk (2 cups)
Heavy cream (1 cup)
Grated Gruyère or Cheddar cheese (1½ cups)
Cooked bacon or sautéed vegetables (1½ cups total)
Onion, finely chopped (1 medium)
Olive oil or butter (2 tablespoons)
Kosher salt (1 teaspoon, or to taste)
Black pepper (½ teaspoon)
Fresh herbs such as parsley or chives (optional)
Prepare the baking dish – Grease the dish generously with butter or olive oil.
Cook aromatics – Sauté onion in olive oil until soft and translucent.
Layer the bread – Spread half of the bread cubes evenly in the dish.
Add fillings – Scatter half of the cooked bacon or vegetables and cheese over the bread.
Repeat layering – Add remaining bread and top with the rest of the fillings and cheese.
Make the custard – Whisk eggs, milk, cream, salt, and pepper until smooth.
Assemble – Pour the custard evenly over the layered bread mixture. Press down gently so everything absorbs the liquid.
Rest overnight – Cover and refrigerate for at least 6–8 hours.
Bake until golden – Bake at 180°C (350°F) for 45–55 minutes until puffed and set.
Rest before serving – Let stand for 10 minutes before slicing.
