Turn waffles into a waffle French toast casserole with this simple recipe! After soaking overnight, it's ready for baking in the morning.
Combine eggs, milk, sugar, vanilla, and cinnamon in a mixing bowl. Whisk until the sugar is dissolved.
Cut the waffles in half, like half moons. Submerge each piece in the liquid, let it soak for a few seconds, then place it cut edge down in a 1 quart casserole dish. Continue until the dish is full (snug but not overstuffed). Pour remaining liquid evenly over the top of the waffles. Cover lightly with foil and refrigerate overnight.
Preheat the oven to 400 F. Bake the casserole for 15 minutes, then turn the oven down to 300 F and bake another 15 minutes. If the top begins to get too brown, tent loosely with aluminum foil. Remove from oven and let cool slightly.
Serve with maple syrup, or drizzle 1/4 cup of maple syrup over the whole casserole before serving (your choice).
