Diced pancetta, bacon’s slightly sweeter Italian cousin, is the undercover star of this dish. After being cooked in a bit of olive oil, it’s layered into the mix, providing a savory, salty foil to the eggy bread and cinnamon and brown-sugar laden ricotta.
The overnight soak allows the casserole to take on a trifecta of textures. The bottom bread gets gooey with the flavors of cinnamon and vanilla, the ricotta seeps in between the bread cubes and, after baking, the top crust gets crunchy and golden brown. Best eaten warm, this casserole is the perfect one-dish weekend indulgence.
