Often called a breakfast casserole, the strata is a classic American dish that masterfully combines stale bread and eggs into a layered, savory bake. Think of it as the satisfying union of a frittata and a bread pudding. While it’s a staple at brunch, this versatile dish is equally suited for a casual supper.
The beauty of a strata lies in its flexibility. At its core, you need day-old bread and a rich custard. Beyond that, the ingredients are adaptable, making it an excellent way to use up leftovers. A key to success is using a sturdy bread. Delicate options like brioche can become too soft, while robust choices such as sourdough or ciabatta provide a pleasant, chewy texture that holds up well.
For the best structure, many recipes recommend drying fresh bread slices in a low oven before assembly. This step helps the bread maintain its integrity and absorb the custard without turning to mush. However, if your bread is already thoroughly stale, you can skip this step.
The custard itself is typically a simple mixture of eggs and dairy. Using a combination of milk and a richer ingredient like cream or crème fraîche helps create a firm, silky result that won’t separate in the oven. For a more complex flavor profile suitable for lunch or dinner, consider replacing some of the milk with chicken stock or a splash of reduced white wine.
When it comes to assembly, the classic method involves distinct layers. Start with a greased baking dish and create alternating strata of your chosen fillings and bread. Popular additions include sautéed spinach, leeks, mushrooms, and various cheeses. A crucial tip is to cook any vegetables beforehand to remove excess moisture, which would otherwise make the final bake watery.
Once assembled, the strata benefits from resting in the refrigerator for at least an hour, or even overnight. This allows the bread to fully absorb the custard, ensuring the layers hold together when baked. A moderate oven temperature is essential to cook the eggs gently without curdling. After baking, let the strata rest briefly before serving; the flavors are best when warm rather than piping hot.
This dish is endlessly customizable. Match your seasonings and add-ins to your taste—mustard, fresh herbs, or a dash of hot sauce are all excellent choices. Whether you stick to a classic combination of spinach and Gruyère or invent your own signature version, the strata is a reliably delicious and resourceful meal.
