Tips and frequently asked questions:
- What caused my French Toast to become soggy?
- Too much milk mixture will prevent the eggs from cooking properly
- If you don’t bake the casserole long enough it can cause the finished toast to be soggy. If it looks at all soupy keep it in the oven longer
- The ideal French toast will be soft on the bottom of the casserole and crisp golden brown on top
- Bread substitute – If you aren’t able to find challah bread we recommend brioche bread as a good substitute
- Warm your maple syrup on the stove or in the microwave before serving. Nothing better than warm syrup!
