Gluten-Free Breakfast Casserole
I have a large family and making a gluten-free breakfast casserole is an easy way for me to make breakfast for my whole family. Breakfast casseroles are easily prepared in a few minutes and can even be made ahead of time.
Two of my favorite casseroles to make my family are my Gluten-Free Cinnamon Roll French Toast Casserole and my Gluten-Free Eggs Benedict Casserole.
Blueberries And Lemon
One of my favorite flavor combinations, especially for Spring, is blueberries and lemon. So I decided that I would create a blueberry lemon breakfast casserole.
If you love the flavor of blueberries and lemon and much as I do, check out my recipe for Gluten-Free Blueberry Scones.
How To Make Gluten-Free Blueberry Breakfast Casserole
Bread Layer
- Preheat your oven to 350° F and grease a 9×13 baking dish with gluten-free cooking spray.
- Cut one loaf of the gluten-free bread into small pieces. Spread the gluten-free bread pieces evenly on an ungreased baking sheet and bake for 5-10 minutes, until nicely toasted. Please watch your oven because all ovens are different. Remove from the oven when toasted and set aside. (photo 1 & 2)
- Add the toasted bread to the pan and sprinkle the blueberries over the top of the bread.
- In a large measuring cup or medium-sized bowl, whisk together the eggs, milk, granulated sugar, lemon juice, lemon peel, and pure vanilla extract until well blended. Pour the egg mixture evenly over the bread pieces. (photo 3 & 4)
Crumb Topping
- In a small bowl, add the gluten-free flour, brown sugar, salt, and melted butter and mix until crumbly. Sprinkle the crumb mixture evenly over the top of the casserole.
- Bake for 1 hour on the middle rack. You can see if it is done by inserting a toothpick into the center of casserole and see if it comes out clean. You will also see the sides of the casserole pulling away from the sides of the pan when it is done. The casserole will also be firm and not jiggly when it’s done. Please watch your casserole because all ovens are different.
Glaze
- Mix all of the ingredients of the glaze together in a small bowl until it’s nice and smooth. Allow the casserole to cool a few minutes before drizzling the glaze on it and serving. Enjoy!
- Cover or store left-overs in an air-tight container and refrigerate. Reheat the casserole in the microwave or oven. This breakfast casserole is even good cold. (I prefer this casserole cold)
Gluten-Free Bread
Gluten-free bread is the key ingredient in this breakfast casserole. Schär is my family’s favorite brand of gluten-free bread. It’s also dairy-free too!
We enjoy the bakery flavor and soft texture of Schär’s Artisan Baker White Gluten-Free Bread. It is also shelf stable (no frozen bread here), vacuumed sealed and bagged for freshness. I do keep it in the refrigerator once it has been opened.
I also love that I can easily find Schär gluten-free products at Walmart and my local grocery store. You can use their store locator to find a store that carries them near you.
Gluten-Free and Dairy-Free Casserole
I have also included a dairy-free option for this casserole. There are three of us in my family that are also dairy-free (me included), so I always try and have a dairy-free option to my recipes.
To make this breakfast casserole dairy-free I used almond milk and Smart Balance butter. Schär’s bread is also dairy-free!
So, now you too can enjoy a gluten-free and dairy-free Blueberry Lemon Breakfast Casserole.
Can I make this ahead of time?
Yes! This casserole can be made ahead of time (even overnight) and refrigerated before baking. Just do not add the crumb topping until right before baking.
Can I freeze the casserole?
Yes! If you have left-overs of the casserole it is easy to freeze. Place your completely cooled casserole in a freezer friendly air-tight container. You can freeze it for several months. You can easily reheat the casserole in the oven at 350°F for 10-15 minutes or in the microwave.
This gluten-free Blueberry Lemon Casserole is so easy to make. It combines the flavors from french toast and a blueberry muffin all in one tasty bite!

Delicious! I made this today and it was so good. Gluten free is always tricky and it’s difficult to find good recipes. This is a winner. Thank you so much.
Can you make with egg substitute like Just Egg?
Hi Kathy, we have not tried that but would love to hear your results if you do!
How is this dairy-free if there are eggs in it?
Hi Georgia! Eggs are not dairy, but actually, a protein that comes from a chicken. Dairy is a food product that is made from the milk of mammals (mostly cows milk).
Just made this today-SO flipping good. Didn’t use the glaze just a sprinkling of powder sugar. It was a huge hit!
OMG is this delicious! I made a lemon glaze to up the lemon flavor. I also make it sugar free, using Monk sugar and also Swerve brown sugar substitute for the topping. Best GF dessert ever. Thank you for all your tips. Other than the sugar substitute I followed the directions exactly.
Delicious!!!!
I made this for a women’s leader ship breakfast. Only one of the women is gluten and dairy free but everyone loved it! I used “I can’t believe it’s not butter” to keep the recipe dairy free. I think that next time I will leave the butter cold when I make the crumble to see if it stays more “crumbly”
We made this for Mother’s Day brunch. It was AMAZING! We made it and baked it the night before, then warmed it up in the morning. The only thing I might change next time is to try it without the icing. The icing was a little sweet for me. It did not detract from the flavor of the casserole, just added sweet. I think next time I will try it without the icing. I also want to try it with raspberries!

Turned out so well for a Christmas morning breakfast. Made it dairy free too. My boyfriend ate practically the entire thing (and he’s not Celiac) and now he’s requesting it for Valentine’s Day too 😂
This casserole tastes like sugary, sweet heaven. If you’re having doubts, take my word and bake it. I have told several people about this, and I’m making it for future get-togethers. Friends will love it! This dish is AMAZING
So delicious! Has become a favorite item for our family Christmas Eve brunch!
I started making this casserole for my daughter who has celiac, but now everyone enjoys it! Does not seem gluten free. Love the blueberry lemon combination! Bravo!!
Superb Casserole! Even my non-gluten free friends loved it and wanted the recipe.
Thank you so much Patricia for the wonderful 5-star recipe review! I am so happy that you and your friends (even your non-gluten-free friends)loved the casserole. Thank you again!
