Treat your family to a delicious, savory breakfast casserole with Gluten-free Everything Bagel Strata! A delicious make-ahead breakfast full of sausage, cheese, and eggs.

I tend to collect things in my freezer... gluten-free bread, bagels, and frozen pizzas to name a few. (Please tell me I'm not alone!) When it gets to the point that it's hard to close the lid, I know it's time to purge. The other day, I found a sack of Trader Joe's Gluten-free Everything Bagels and I thought an overnight breakfast strata sounded like a fun way to use them up! This gluten-free breakfast casserole is loaded with eggs, cheese, and breakfast sausage, it's like a savory bread pudding. While this would be a fun breakfast for any day of the week, I would most likely serve this on a special occasion like Christmas morning or for a fun weekend breakfast.

Why I love this breakfast Casserole

You can make it ahead! This can sit in the refrigerator overnight making it the perfect gluten-free brunch recipe!
Customizable! You can use any type of cheeses, sausages, or bacon. You can even use regular bread instead of bagels... or even plain bagels instead of everything. It is a great way to use up ingredients in your fridge and freezer.
It's Easy!

Ingredients in Gluten-free Everything Bagel Strata

Ingredients for the breakfast casserole measured out in bowls, bread cubes in the baking dish.

Gluten-free Everything Bagels: I used Trader Joes. Any type of savory bagel or bread would work if you'd rather use up what you have on hand.
Breakfast Sausage: Cooked and crumbled. I used Applegate chicken breakfast sausage because we have to avoid pork in our house. Use your favorite kind of breakfast sausage or substitute bacon if you prefer.
Cheese: I used cheddar-jack.

Overnight Breakfast Casserole

To make this casserole ahead, prepare and cover the unbaked casserole with foil. Let it sit in the refrigerator overnight. Let the strata sit at room temperature while you pre-heat the oven.

If you want to make and bake the casserole on the same day, prepare and allow 30 minutes for the casserole to soak up the egg mixture before baking.
