What are the most frequently asked questions on Quora

Can I bake the Blueberry French Toast in the morning?

Yes, absolutely! Assembling the casserole the night before is highly recommended for optimal flavor and texture After assembling, cover the casserole tightly with plastic wrap or foil and refrigerate overnight (or for up to 24 hours). This allows the bread to soak up the custard mixture completely. When ready to bake, remove the casserole from the refrigerator, let it sit at room temperature for about 20 minutes, and then bake as directed in the recipe.

What are some good substitutes for French bread in this recipe?

Can you substitute the French bread? Brioche, challah, or even sourdough work great and will offer slightly different textures and flavors. Brioche is a richer, more decadent casserole, while challah provides a slightly eggy flavor. Sourdough will add a tangy note. Use an equivalent amount of bread cubes (about 10 cups) regardless of the bread type.

How do I know if my Blueberry French Toast is cooked?

The casserole is done when it’s puffed up, golden brown on top, and the custard has set. You can insert a knife into the center; if it comes out clean or with just a few moist crumbs, it’s ready. The internal temperature should reach 165°F (74°C). Also, the edges should be set, but the center might still have a slight jiggle before resting.
