Brioche French Toast Casserole


If you want a stress-free brunch, try our Overnight Brioche French Toast Casserole with lemon and blueberries. Make it the night before and pop it in the oven in the morning.


If you need the oven to make other things like bacon or a frittata, make this first. It doesn’t need to be served hot, and can sit out for some time. Just cover it with a flour sack towel, so it stays warm and doesn’t sweat. If the tops of the bread look dry, don’t worry. The french toast casserole, or strata, or even bread pudding – whatever you call it – will be incredibly moist and delicious.


You can customize the Brioche French Toast Casserole with what’s in season. Substitute oranges for lemons and raspberries for blueberries. Or try mixed berries!
