What You’ll Love About This Blueberry French Toast Casserole

This Blueberry French Toast Casserole hits the mark, with its refreshing lemon + juicy blueberry combination:

  • You’ll love the five whole tablespoons of lemon curd in this French toast bake. You can use your favorite brand of lemon curd, though we highly recommend saving this lemon curd recipe so you can make your own way-better lemon curd that promises to elevate every toast, cracker, or baked good you use it on.
  • The zest of 2 whole lemons goes into this blueberry lemon French toast bake. We can’t think of anything more refreshing than fresh lemon zest.
  • Plenty of fresh blueberries provide all the juicy, sweet berry abundance in this breakfast casserole.
  • Because this French toast casserole rests in the fridge overnight, it’s best to use fresh blueberries. Try to nab in-season pump, sweet berries for best results.

Blueberry Lemon Sauce (4 Ingredients)

You’re about to meet the most luscious blueberry sauce ever known to woman. It’s so delectable, you’ll probably want to eat some of the sauce with a spoon and we’re not here to stop you.

Aside from water, all you need are:

  • Fresh or frozen blueberries. You read right about fresh blueberries being a must for the French toast itself, but feel free to use up any frozen blueberries you have for the sauce.
  • After zesting your lemons for the French toast casserole, juice those lemons for the sauce.
  • Plain, regular sugar is all you need for balanced sweetness.
  • Cornstarch is an ideal thickener for this fruity syrup.

Tip: blueberry lemon sauce can be made in advance. Extra sauce keeps well in fridge.

After baking your blueberry French toast casserole, generously pour on the sauce. If you have a crowd who likes their French toast extra saucy, feel free to double the sauce. It keeps well for future use on Fluffy Belgian Waffles and Fluffy Buttermilk Pancakes, too.

Commonly Asked Questions

Can I use frozen blueberries for this French toast casserole?

For this recipe, we highly recommending using fresh blueberries, as frozen blueberries contain excess water that would alter the casserole portion. However, you can use frozen blueberries for the sauce!

Can I make the blueberry sauce ahead of time?

Yes, this blueberry sauce can be made several days ahead of time. Keep it covered airtight and chilled until ready to use. If needed, warm it up slightly prior to using.

What kind of bread is best for French toast casserole?

The more hearty the bread you use, the better it will stand up to the overnight soaking. We recommend a large loaf of hearty French bread.

What is the best way to soften cream cheese?

Place cream cheese in a glass bowl, cover, and microwave in 20-second increments until it is nice and soft. This always helps to ensure cream cheese mixes in smoothly without clumps.

    Blueberry and lemon is the perfect flavor combo and French Toast has to be on the top of my breakfast favorites. So this recipe was a no-brainer to make as soon as I saw it. I love the fact that the blueberry sauce is drizzled on after the casserole is cooked then all that lemon flavor comes through so much better on the French toast itself. This is going to be my go-to for special brunches from now on.
