All food should be accessible and approachable. Technical words like “strata” can seem like a barrier, but the components really show how it’s no more than an egg casserole. A casserole is really the most approachable, friendly recipe to make. And how could it not be? It’s everything baked together in a dish and served as a meal.
The best part of a strata or egg casserole is the fillings. This recipe is full of hearty flavors with a seasonal fall twist. The delicata squash and bacon create a harmoniously sweet and savory combination with just the right amount of smokiness.
What is a strata?
Strata is nothing more than an egg casserole layered with bread and a choice of meats, cheeses, and extras. The defining factor is that a strata always has bread to soak in the eggy custard and is puffier or soufflé-like once baked.
The best part about a strata is that it can be made the night before serving. Pour the egg custard over the bread and filling, wrap it up tightly, and store in the refrigerator overnight. Bake in the morning for a stress-free breakfast.
Can you switch up the ingredients?
I will always say that every recipe should be given at least one chance as written. However, a strata is one of the easiest dishes to switch up and customize to one’s personal preference or ingredients on hand. The base is the bread and custard, and everything else is extra. Here are some changes that could be made:
- The Swiss chard can easily be switch out for spinach or kale.
- The bacon can be substituted for sausage or left out entirely.
- Cheese is obviously interchangeable. Personally, I think goat cheese is a great replacement.
