Sometimes, I really feel like I’m getting old.

As a kid, I remember scoffing at anything lemon and heading straight for the chocolate, or if not chocolate then surely caramel or something ridiculously over the top and sugar loaded.

But over the last few years, I’m happy to report that my tastes are evolving, and I am indeed becoming a Real Grown Up. Or as close as possible 😉

I find myself craving fresh foods and flavors, and would much rather have something light and citrusy, or loaded with fresh fruit, than something more indulgent.

And if that light and citrusy thing, loaded with fresh fruit can be breakfast or lunch or brinner, and is packed with whole grains (Dempster’s 100% Whole Grains Bread — made with no artificial flavours or colours), protein (eggs and milk), and made without artificial ingredients, you can absolutely count me in.

It certainly doesn’t hurt that it tastes amazing!

I consider myself lucky that my kids love lemon as much as I do. It’s something we all love and there are no fights over breakfast, lunch or dinner when this is on the table. We can easily polish off most of the casserole dish on our own in one sitting!

Because I know we don’t always have 2 to 4 hours to wait for breakfast, I wanted to include oven instructions as well. The same recipe is easily made either way, making it perfect for a late holiday brunch or a quick, no-effort hot breakfast on a weekday morning.

If you don’t want to add the poppy seeds, feel free to leave them out — I think they look pretty and they are actually good for you, too! You can also add the berries right in the French toast before baking if that’s what you prefer. Feel free to mix and match to suit your tastes!

    The heading says overnight and the instructions say 3-4 hours. So actually I guess this is not an overnight recipe. Otherwise it sounds pretty good.

    I used to hate anything lemon related when I was younger but now I can’t get enough of the bright zippy flavor, especially in the winter. This overnight french toast casserole sounds like a dream.

  3. Gayle @ Pumpkin 'N Spice says

    I was the same way when I was little, too! I really didn’t like anything with lemon. But, now that I’m older, I’m definitely coming around. This french toast looks incredible, Ashley! I’ve never made it in the slow cooker before, so I’m loving this fun twist!
