Preparation Time10 min

Slow Cooker Time LOW4 hr



  • 1 cup lightly packed brown sugar
  • 1/4 cup melted butter
  • 1 teaspoon cinnamon
  • 12 slices bread (see note)
  • 1 1/2 cup blueberries, either fresh or frozen
  • 5 eggs
  • 1 1/2 cup milk
  • 1 teaspoon vanilla
  • 1 teaspoon salt
  • Maple syrup and fresh blueberries for garnish


In a small bowl, mix the brown sugar, butter and cinnamon to a paste.

  1. Spray the slow cooker insert with cooking spray and sprinkle about 1/3 of the brown sugar mixture into the bottom of it. Use the rest to spread evenly on all of the bread slices.

  2. Layer half the bread into the slow cooker, cutting or tearing it to fit, and sprinkle all of the blueberries on top.  Layer the remaining bread on top in a slightly overlapping pattern.

  3. In a large mixing bowl, combine eggs, milk, vanilla and salt and whisk to completely mix.  Gently pour over the bread layers and press the bread down to submerge it in the milk and egg mixture. Cover and refrigerate overnight or for at least 2 hours.

  4. When ready to cook, place the insert into the slow cooker and set it to LOW heat for 4 hours.

  5. Serve with warm maple syrup and a garnish of fresh blueberries.  


  1. Make this recipe in a slow cooker with a removable insert.

  2. A firm sandwich bread works best, but you may substitute whatever bread you have available. This is a good place to use up bread which is no longer fresh as that will hold together best in this dish. If you use a baguette, cut it into ½ inch slices and use about 20 slices.

I would love to try this recipe! I have never made an overnight French toast, so I can't wait to give this one a try.

I absolutely LOVE me some French toast. I don't eat it nearly enough! Blueberries would be my fruit of choice, fresh ones too. Here is what drives me crazy about breakfast slow cooker recipes. How can I make this work for me when it has to cook for 4 hours on low? Do I get up at 6am to start it so that we can eat by 10? I mean, I wish there was some kind of way to work around this. I have seen a few recipes in the past where you can pop it in the night before and it will be ready when you wake up. But those were not for French toast! I still love this dish, though. It might be more for a "breakfast for dinner" recipe for this family.

Hi princess6860504, we haven't tested this, but you could try cooking this recipe on high and halving the cooking time. Although, you may want to keep an eye on it the first time you try it. I hope that helps! - Natalie, Editor of AllFreeSlowCookerRecipes

This looks so good! I can't wait to try it out this weekend. And that information about the origins of French toast is fascinating! I had no idea :)

I've never been a fan of french toast but this recipe just may change my mind and I'll definitely have to try it with other fruit. I'm guessing any bread would be suitable, perhaps french? The possibilities are endless really...and I bet adding sausage crumbles or any other breakfast meat you like would make this a great savory dish.

I love this recipe. It is absolutely perfect for a lazy winter weekend at home. It makes your house smell absolutely amazing when it is cooking! My 4 year old son is a very picky eater, but he absolutely loves this dish! I like to mix sliced fresh strawberries with a touch of brown sugar and cinnamon and add the mixture on top at the end.

This is a great idea to serve on Christmas morning. I will add more blueberries after reading the comments below. I bet this smells very sweet while it's cooking- a lot like the sweet candles I buy. Would you recommend plain white bread?

Love this--it'd be so great to make on the weekend.

What kind of insert is this recipe talking about and how do you use it?

This is the slow cooker insert the recipe is talking about. This is pretty standard for slow cookers; most come with this insert. Hope that helps! - Editor,

Overnight recipes are the best (and of course French Toast is pretty good too)!

I think it needs more blueberries. I'm a fiend when it comes to those bite sized berries.

This recipe had too few blueberries for my taste, but it was otherwise pretty tasty.

This French toast was really sweet... almost more like a dessert, which I loved! I think it'd be great with any fruit if you're not a fan of blueberry.

Yum! I love French toast casseroles even more than traditional French toast, so this easy breakfast recipe was super satisfying. I loved how curstardy the bread was.

I ate a bowl of this inside about 30 seconds. Absolutely delicious. I would definitely eat this for breakfast often.

I'm usually not a fan of blueberries in my breakfast dishes, but this French toast proved me wrong. It was like a hot blueberry muffin, but both gooey and chewy. Each bite was a warm, fruity delight.

OH MY GOODNESS. This breakfast casserole was so soft and chewy. The warm blueberries were my favorite part, for sure. I want to make this for breakfast every single day!

This French toast casserole was SO GOOD! The blueberries were perfect.

Made this as our "dessert" for our Sunday family dinner (where we had breakfast for dinner!) this weekend and...IT'S A WINNER! Came out perfect in texture, taste (no syrup needed, even!) and appearance! I will definitely make it again, doubling the recipe! LOL! Yumm!!
