This savory breakfast casserole is cheesy and full of vegetables. A great weekend breakfast, especially for guests
I can't post a week full of breakfast recipes without at least one breakfast casserole recipe, right?
I mean, breakfast casserole is amazing! I've never had one I didn't like.
This one is a little bit fancier than the one I usually make.
Usually, I just use cheddar. This time, I used three different cheeses {fancy, right?}.
If you can splurge on cheese, it's totally worth it for this recipe. This is my favorite breakfast casserole I've ever made.
With my regular breakfast casserole, I feel like you know it's healthier because the whole wheat bread flavor is pretty obvious. But in this one with the stronger cheese flavor {from the Parmesan and Gruyere cheeses}, you hardly notice the whole wheat.
If you don't want to spend the extra cash on Gruyere, you can either use Swiss cheese or more Parmesan. It will still be delicious!
Just so you are aware, there will be another breakfast casserole type recipe this week. But it's sweet - totally different from this gem.
I like making savory breakfast casseroles because it's easy to add in veggies. And I love starting my day with veggies.
Plus, this is a great weekend breakfast, especially when you have guests & want to impress.

Notes
*Oh and be sure to take the casserole out of the refrigerator before you start preheating the oven. You don't want to put a cold casserole in a hot oven. It doesn't end well {a cracked baking dish & egg/bread all over your oven is not a good way to start your morning. Unfortunately, I know from experience...}
God Bless America! If you're feeling patriotic this 9/11, you can always make this firecracker cake or cake mix cookies in honor of all the people who have fought for our country ๐
