Overnight Everything Bagel Breakfast Casserole
It has been a hot minute since we’ve made a breakfast casserole here on Inspired by Charm. I don’t know about you, but I’m a big fan of breakfast casseroles, especially when you can prep them the night before. I mean, who wants to get up and prepare a full breakfast in the morning? Not me!
Today, I’m taking one of my favorite breakfast casseroles and giving it a twist; it is getting a flavor upgrade by using everything bagels. I have been making this particular breakfast casserole for years. I always used standard white bread in times past, but this time I wanted to try something different and I’m so glad that I did!
Let me tell you, friends, I loved this recipe before but adding everything bagels is a game-changer.
I assume that any brand of everything bagels will work, but I used and recommend Dave’s Killer Bread Epic Everything Bagels for this recipe. Their flavor and softness are perfect in this dish.
This Overnight Everything Bagel Breakfast Casserole is just bursting with flavor in every bite. You and your guests are going to love it. When I made this for my family, everyone was asking for the recipe.

How to Make Overnight Everything Bagel Breakfast Casserole:
Begin by cutting the bagels into 1/2 – 1 inch cubes. Spray the bottom of a 9×13 baking dish with cooking spray, then add in the cubed bagel pieces. As I mentioned above, I used and recommend Dave’s Killer Bread Epic Everything Bagels for this recipe. Their flavor and softness work really well for this dish.
Spread the cooked sausage over the bagels. Then, sprinkle with the cheese, chopped red bell pepper, and green onions. Mix slightly with your hands to combine. I’ve provided a full list of the ingredients and detailed recipe instructions in a printable recipe card below.
In a large bowl, add the eggs, half and half, dry mustard, salt, and pepper. Whisk to combine. Pour this mixture over the bagels and sausage.
Cover the dish with foil and refrigerate for 8 hours or overnight.
Before baking, preheat your oven to 350 degrees F.
Bake covered until set and lightly golden on top: about 60 minutes. (You can remove the foil for the last 10 minutes of baking for a nice golden top.) Remove from the oven and allow the casserole to set for about 15 minutes before serving. Sprinkle with chopped green onions to garnish.
That’s it! As I mentioned above, the flavor combination in this breakfast casserole is on point.
I make this any time of the year, but it’s a great dish for the holidays, especially when your house is full of people and you need something to feed a crowd.
I hope you’ll give this Overnight Everything Bagel Breakfast Casserole a try. Enjoy!

Thank you for sharing and loved that I could put it together the njight before
This is the best version of this standard recipe I’ve ever seen. Everything bagels are a genius idea!
Making it this coming Christmas, thanks! Was thinking of some breakfast casserole so getting your email with this recipe was perfect timing! Merry Christmas.
Hi Michael, where can I purchase the bread, this looks delicious.
Thanks, Charlotte
It’s at most grocery stores theses days. You can also check their website for retailers.

Made this casserole for visiting family – it was a huge hit! And what a relief to have something already assembled that you just pop in the oven. Thanks, Michael!
Made this for Christmas morning breakfast, baked while we had coffee and opened presents. Can I tell you, the smell was warm and delicious! I took the foil off for the last 10 min to get the crispy top…so nice! Another winner, thank you Michael!
Yay! So happy to hear this! Thank you so much!!

I’ll definitely be trying this out for hubby and myself for New Year’s breakfast. But since it’s just us two, I’m going to try halving. Let you know how it turns out! Merry Christmas!
It looks yummy – I’ll be trying this one – thanks for sharing!
Can it be rewarmed for a second meal?
We recently tried this recipe- it was a hit! Thank you for always having the best recipes!
Mmmm! Hi Michael..I just wondered if you think this is something that could be assembled in the dish the night before? Or maybe partially and then do the eggs, half and half, etc in the morning?
Yes. It’s an overnight casserole so it needs to be made the night before. I explained that in the recipe.

Michael, if this Bagel Casserole (with sausage) is as luscious as your Easy Overnight Breakfast Casserole (with ham and bread), I will never be without a winning breakfast recipe! I’ve made the latter many times.Innkeeper favorites are so treasured! Unlike bloggers who post dozens of recipes they’ve barely tested or never tasted, you share fewer recipes but only the best — ones you’ve curated, dear to your heart. I greatly appreciate not having to scroll hundreds of recipes to find a handful that rate five stars. I can trust your recipes, and that’s a huge plus when deciding to invest my resources. Michael, while you’ve said you might need an infusion of energy at this season in life, I sense you feel the love from your readers. As in nature, we humans need to rest. Hugs, and holiday warmth within your cozy home.
