If you loved my easy breakfast bowls, then you’ll love this casserole even more! This recipe is perfect for making on Sundays for an easy breakfast option throughout the week. You can also freeze the casserole (before the last step) and bake it later, especially if you want to prepare it ahead of time for a family or holiday breakfast gathering!
TIP: I used fresh ingredients for this specific version, but you can skip a few steps by using frozen veggies!
Breakfast Casserole
If you loved my easy breakfast bowls, then you'll love this casserole even more! This recipe is perfect for making on Sundays for an easy breakfast option throughout the week. You can also freeze the casserole (before the last step) and bake it later, especially if you want to prepare it ahead of time for a family or holiday breakfast gathering!
- 12 eggs

Preheat oven to 425 degrees. Grease 9×13" dish with olive oil.
-
Fry bacon until crispy in skillet or bake in oven at 425 until crispy (about 15-20 minutes, rotating halfway through. Transfer to paper towel to cool, then chop into small pieces. Save your bacon grease!!!

Add remaining bacon grease to skillet. Over medium heat, add the onions and cook slowly (about 25 minutes) until onions are soft and caramelized. Remove from heat.
-
In a bowl (or stand mixer), beat eggs and milk together.
-
Assemble the casserole. In the greased baking dish, add the sweet potatoes and brussels sprouts. Sprinkle with remaining garlic powder. Add onions and bacon. Sprinkle with cheese. Pour egg mixture evenly on top.
-
If FREEZING, wrap casserole dish tight with foil and place in freezer.
-
Bake at 400 degrees for 30-45 minutes or until the edges are browned and casserole is bubbly. Allow casserole to cool before slicing.
I think by accident you left out the quantity of eggs on the ingredients list. Looks great though!!
OMGGGGGG — THANK YOU SO MUCH for pointing this out!!!! Updated!!!!
This might be our Easter brunch! Thanks for sharing.
Where do you put the other half of the garlic?
Half of it goes on the potatoes before roasting. The other half is sprinkled on casserole during assembly! 🙂
Wow, thank you! I love breakfast casseroles but having to use gluten-free bread makes them a bit less tasty. I would never have thought of using brussels sprouts and sweet potatoes but I love all those ingredients, so we’ll see how they taste together. I also love the ability to make and freeze, as there are only two of us at home now and I can make and freeze half.
