There is just nothing better than a make-ahead breakfast. Ever. Any day of the week.

But, they are even more awesome around the holidays — right?! You’ve got guests staying over, or a holiday brunch party, and who wants to get up early and slave over 10 different skillets, griddles and casserole dishes?? Not I.

I actually don’t really ever want to get up early and slave over breakfast, which is why we often do breakfast for lunch or dinner when we want something a little more special.

I’m partnering with the Peanut Bureau of Canada (again! Did you see my Healthier No Bake Chocolate Peanut Butter Cookies or my Chocolate Peanut Butter Pretzel Candies?? <— those need to go on your holiday gift giving list!) to bring you this fabulous holiday brunch recipe!

This Peanut Butter French Toast Casserole was a natural progression from this Peach Cobbler French Toast Casserole and this S’mores French Toast Casserole — and one you absolutely need to add to your repertoire! If I’m being totally honest, I think it’s my favorite French toast casserole on the blog to date.

Between the eggs, milk and the peanut butter, there’s enough protein in this breakfast to keep you going through all the festivities. I like to use a whole grain bread for fiber, and add just enough maple syrup so that you can still call it breakfast. If you want to healthify things even more, feel free to top with vanilla Greek yogurt and fresh berries for a PB&J style breakfast.

If you want to go totally decadent? Try a dollop of whipped cream, berries and a drizzle of chocolate or maple syrup! Or my favorite? A sliced banana and extra maple syrup. <— seriously SO amazingly delicious.

    I love peanut butter and I love French toast! Perfect combination 😀. Question – would using natural peanut butter do anything to the consistency?

    Your site has quickly gone to my first stop for new ideas to try. This was incredible once I cut up a banana as suggested to serve over the top. Lately I have been taking ideas and trying to make it a little lighter, I used egg beaters, unsweetened vanilla almond milk, and PB2 fit powdered peanut butter. Using the same sizes you recommended, came out fantastic!

    Oh I know I don’t need to tell you how much I ADORE this!!! Peanut butter-obsessed person over here, and this is maybe the best breakfast I’ve ever seen in my life!! Love this, Ashley. Love a good breakfast casserole anyway, but the PB?? Gah!

  4. Gayle @ Pumpkin 'N Spice says

    Make-ahead breakfasts are the best! Especially when it involves peanut butter and french toast. I can never get enough of french toast bakes because of how easy (and delicious) they are to prepare. What a great idea for house guests!
