Strawberries, Sleepovers, and the Easiest Fancy Breakfast I Know; Make Ahead Challah French Toast Casserole

This baked French Toast Casserole is my go-to when I want to impress without the 7am wake-up call
Summer break has arrived, bringing with it slow mornings with my kids, gallons of cold brew hogging space in the fridge, and plenty of trips to the local ice cream shop. I like to give my children a week of unstructured downtime at home—just rest, play, and sleeping in. That is, before we dive into busy beach days, pool visits, a few weeks of camp, and lots of quality time with the tribe of cousins we’re lucky to have. I don’t want to spent time stressing out over breakfast! That’s where the Make Ahead Challah French Toast Casserole saves the day!
I grew up with my own small pack of ragtag cousins. We were a semi-feral bunch, left entirely to our own devices in classic elder millennial fashion. Think The Goonies, but Cape Cod style. Our summers were made of fluffernutters, sandy feet, endless bottles of sunscreen, and bike rides to the beach. You wouldn’t see us again until dinner… and it was glorious.
Now, with my own crazy crew of kids and their cousins underfoot, I like to make sure they’re well-fed before they start making memories of their own.
But I’m always scrambling for a special breakfast when guests stay over… what to make?
