Whether you’re having overnight guests, planning a special brunch, or just wanting something different to serve your family in the morning, you’ll want to try this delicious overnight breakfast casserole.
As a former innkeeper, breakfast is one of my favorite meals. (I say “one of” because, if I’m honest, I like every meal!) I have fixed breakfast for many people and have long enjoyed experimenting and creating new recipes to start the day.
What I love about this overnight breakfast casserole is that it’s a blend of classic flavors that many folks seem to enjoy. However, it also serves up a lot of flexibility.
How to Make Overnight Breakfast Casserole:
Simply by swapping breads, cheeses, meats, or vegetables, you can customize this casserole to please any palette or come up with a new flavor combo each weekend of the year.
For this particular recipe, I started with French bread and a dozen eggs. (Makes sense for breakfast, right?)
From there I went with traditional breakfast flavors, including ham, cheddar cheese, and chopped peppers. For even more flavor, I added dijon mustard, garlic powder, salt, pepper, and thyme.
All of this gets mixed together and refrigerated overnight. Come morning, all you do is turn on your oven and bake the casserole.
This is another huge perk of this recipe, especially if you’re not a morning person.
Now just slice, serve, and enjoy! Breakfast is ready!

Easy Overnight Breakfast Casserole
Ingredients
- 6 cups cubed French bread
- 1 cup cubed ham
- 1 cup chopped peppers (red, yellow, orange, or green)
- 1 1/2 cups shredded white cheddar cheese
- 12 eggs
- 2 cups milk
- 2 teaspoons ground Dijon mustard
- 1 teaspoon garlic powder
- 1 teaspoon finely chopped fresh thyme
- 1 teaspoon kosher salt
- 1/2 teaspoon black pepper
- 1/4 cup shredded Parmesan cheese
Instructions
- Begin by preheating your oven to 350 degrees F. Spray a 9x13-inch baking dish with cooking spray. Fill with the bread, ham, peppers, and cheese. Mix to evenly combine.
- In a large bowl, whisk together the eggs, milk, Dijon mustard, garlic powder, fresh thyme, salt, and pepper. Pour this mixture on top of the bread mixture. Gently press down the bread with a spoon. Sprinkle with shredded Parmesan cheese.
- Bake 50-55 minutes until the eggs are cooked through. Cover the pan with aluminum foil if the top begins to brown too quickly. (If preparing the casserole in advance, cover the baking dish with aluminum foil and refrigerate overnight. Bake as directed.)
- Garnish with fresh thyme and slice to serve.
Each Christmas I make an overnight casserole for Christmas morning. I decided to try your recipe. My husband said this was the best one yet!! I agree! This will be my go to casserole each year Christmas!! So delicious!! Thank you for the wonderful recipe! I love your site also, I have followed you for a while now. (and you are just adorable) Happy New Year!!! Hugs!!
This recipe seems like a great opportunity to empty out the fridge using ingredients that may expire soon, right? I love it! I especially love that you can prep it the night before and just bake it in the morning…so I could throw it in the oven, take my dogs for a walk, and when we come back STARVING, breakfast.is done! Ha!
I’m keeping this recipe in mind for the holidays as well.
Thanks for sharing, Michael!
I just discovered your recipe when you reposted it and made it last week. Since there are a couple of vegetarians in my family I left out the ham and added in some mushrooms and lightly cooked fresh spinach; kept everything else the same. It was delicious! Wonderful to serve on these cold January mornings.
This recipe was a complete sensation!! It was a total hit! Incredibly delicious!! Made the overnight version. Used green peppers only. Thank you so very much for sharing! Readers, you will love this recipe!
This overnight breakfast casserole was such a big hit. My family loved it! Thank you for sharing!
This looks amazing! I’m definitely going to give this a try!
This looks amazing. I love the idea of preparing it overnight. Yum!
I’ve made this dish before, except I made mine sweeter, more like a bread pudding (same basic recipe). I used the bread (any white or whole wheat), eggs, milk and cinnamon. I layer in blueberries. Great with syrup and sausage on the side. For years, this was my go-to for Christmas morning.
Wow! That sounds delicious! I actually want to make something like this using cinnamon rolls. Stay tuned!!
