Easy Veggie-Loaded Breakfast Casserole

This is a sponsored conversation written by me on behalf of Horizon Organic. The opinions, recipe, beautiful food photography and text are all mine. This easy veggie-loaded breakfast casserole is perfect for serving a crowd (like the PTA or overnight guests) OR going into the lunchbox alongside a single-serve Horizon Organic milk carton.

As a momma, I'm always trying to add more fruits and veggies into my kiddo's day; so breakfast is a great place to start!!

This easy breakfast casserole includes:

  • bell pepper
  • corn
  • cauliflower
  • grape tomatoes

That said, this casserole is totally versatile! So feel free to use whatever veggies you have on hand. Other things that would work great: small bits of broccoli, spinach, grated sweet potato, asparagus, grated carrot... the possibilities are endless!

I made this casserole in a disposable pan for the PTA kickoff meeting at Babycakes' school and paired it with fresh berries + blooms from Sprouts! It would also be perfect to make for a friend who just had a baby.

It's such an easy recipe to double! Make one for a friend and one for yourself!

Alternatively, you can make the recipe in single serve ramekin dishes so that the individual portions fit PERFECTLY into a lunchbox.

PRO TIP: Just place them on a sheet pan for easy in and out of the oven.
