I use my flat whisk for this and it makes things super easy!

(My flat whisk could quite possibly be my favorite kitchen tool in the whole wide world. I use it to whisk eggs together in this recipe, or for scrambled eggs, or even if I have a powdered mixture that needs mixed. It mixes it so well! You can see this must-have kitchen tool, along with every other “Must-Have,” kitchen tool in my post: My Favorite Kitchen Tools )

Next, simply pour the egg mixture over the bread pieces and make sure each piece has been covered or submerged to let that bread soak up that amazing custard mixture!
