How to Make Slow Cooker French Toast Casserole
All it takes are three easy steps and the crockpot does most of the work!
Step 1: bread
- I like to use brioche bread which is hardy enough to soak up the custard without falling apart when cooking., but challah, French bread, Texas toast, and Pullman bread which have dense crumbs are also great options you can use.
- Use stale, dry bread as the excess moisture in a fresh loaf can make the french toast casserole soggy.
- Unfortunately, I could only find sliced brioche at our neighborhood grocery store. Try to use a whole loaf if you can and cut to the desired thickness.
Step 2: custard mixture
- If you want to cut down on the fat, feel free to swap whole milk for half and half but note that the custard will have a less rich flavor.
- You might want to strain the egg-milk mixture in a fine-mesh sieve to rid of streaks of egg whites.
- Don’t skip the salt as it helps balance the creaminess of the dish.
- Want to add grown-up fun? Whisk in a shot or two of Bailey’s, bourbon, or Cointreau to the mixture.
Step 3: walnut streusel topping
- I like walnuts for this recipe but almond slivers or chopped pecans are also good alternatives.
- Use cold butter and try to chill the streusel mixture for a few minutes before sprinkling on top of the french toast so they’ll cook up into crunchy buttery crumbs.
- I don’t normally add sugar to the custard as the brown sugar in the topping adds enough sweetness.
The hardest part of this slow cooker french toast recipe is waiting for the slow cooker to do its magic but I promise your patience will be rewarded. Entertain your guests, go about your chores, and in 3 to 4 hours, you’ll have a rich custardy bread with buttery topping everyone won’t be able to get enough of!
It’s simple comfort food you’d love cozying up to!
