And is there anything better than brunch on a Sunday morning?
On the weekends, I enjoy having time to actually cook breakfast. It’s a nice change from my trusty grab-and-go breakfasts during the week, and my husband seems to enjoy it, too.
Family, a refreshing mimosa, and this vegetable breakfast casserole = the perfect weekend brunch!
This casserole is absolutely LOADED with vegetables, making it super healthy and filling. But don’t let that fool you, it’s actually tasty, too.

Making This Vegetable Breakfast Casserole
After toying around with this recipe, I’ve decided that there is one ingredient that absolutely has to be included when you make it:
You do have to roast it ahead of time because it won’t cook enough just thrown in raw. But oh-em-gee, is it worth the trouble. It adds a nice sweetness to the casserole that just can’t be substituted.
A little sweetness in the middle of all the savory is ridiculously delicious.
Another ingredient I’ve been experimenting with has been the Trader Joe’s Everything But The Bagel Seasoning.

Because it’s not salt-free like my homemade salt-free seasonings, I try to use it in moderation. I really should work on making my own salt-free version.
If you don’t have the seasoning on hand for this casserole recipe, if you want to make a lower-sodium version, or if you just don’t have a Trader Joe’s near you (I feel your pain), you can substitute it for 2 teaspoons sesame seeds, 1 teaspoon onion powder, and 1 teaspoon garlic powder.
Pro tip: Try topping the casserole with half of an avocado and some salsa mixed with plain Greek yogurt or sour cream. I just did, and it was soooo good. Avocado really does make everything better, doesn’t it?
