You guys this might be the EASIEST recipe I’ve ever made.  Seriously.

After a full week of meal prepping, I had a ton of leftover veggies that I wanted to use up so I thought why not roast them in a casserole dish and throw some eggs on top!  This dish is literally as simple as that.  And it tastes so effortlessly delicious!!  The perfect hearty breakfast to jump start your day that you can feel good about eating.  It’s also a great way to use up any leftover vegetables just sitting around your kitchen that you don’t want to go to waste.  I almost wish I had leftover bell peppers because I would have thrown those in too!

Ingredients You’ll Need

  • sweet potatoes – you’ll need about 2 cups of sweet potatoes evenly cut into 1/2 inch cubes so that they cook evenly in the oven.  I peeled my sweet potatoes, but feel free to leave the skin on for a boost of nutrition!  If you don’t have sweet potatoes, you can use red or white potatoes, butternut squash or even pumpkin.
  • broccoli – roasted broccoli might be my favorite thing in the whole world as it gets perfectly crisp and flavorful.  You could also use sliced brussels sprouts, asparagus, green beans, bell peppers.
  • red onion – adds a nice savory flavor to this dish as well as a pop of color.  You could also a white or yellow onion, shallots or even sprinkle on some green onions after baking.
  • eggs – adds essential protein to this dish and makes this a complete meal.
  • olive oil – I like to use a good olive oil that doesn’t have to be expensive, just make sure it’s cold-pressed and organic for the most flavor (in my opinion).
  • cheese – I sprinkled some grated gruyere cheese over top, but you could use any type of cheese you like best.  Shredded cheddar cheese, mozzarella, feta cheese or parmesan all make great options.
  • seasonings – a simple combination of salt, pepper and red pepper flakes for a kick of spice and to really make these flavors pop.
  • fresh herbs – I topped this with some chopped fresh parsley, but you could add fresh cilantro, basil, dill, thyme, or even fresh chives.

How to Make Roasted Veggie Egg Casserole

  1. Roast veggies – In a large bowl, toss together sweet potatoes, broccoli and red onion with 2 tablespoons of olive oil and season with salt and pepper.  Transfer the veggies to a baking dish or skillet coated with nonstick cooking spray and roast in the oven at 425 degrees F for 20 to 25 minutes, tossing veggies once halfway through.
  2. Crack the eggs on top – Remove the skillet or baking dish from oven and reduce oven temp to 400 degrees F.  Using a spatula or spoon, create 5 little spaces for your eggs and crack one egg into each hole.  Top with shredded cheese and bake an additional 6 to 10 minutes (depending on how you like your yolk), until egg whites are set and yolks begin to thicken.  For a runnier yolk, 7 minutes seemed to be the best!
  3. Serve and enjoy!  Season with additional salt, pepper and some red pepper flakes for spice and top with extra cheese and some fresh chopped parsley or green onions.  I also like to drizzle a little sriracha over top for even more heat!

Tips, Tricks and Substitutions

  • Change up the veggies.  I like to use up whatever veggies I have leftover in my fridge so you can easily make this a seasonal dish.  Butternut squash and brussels sprouts would taste amazing roasted together or you could sub white potatoes for the sweet potatoes, cauliflower instead of broccoli, or even add in additional veggies like bell peppers, zucchini, tomatoes or even some leafy greens like spinach or kale.
  • Add more protein.  You could also add some sliced chicken sausage to the skillet to cook along with veggies for some additional protein or add some cooked ground sausage or chorizo for an even more flavorful dish.
  • Use a cup to easily add the eggs.  This is a little trick I like to do that easily adds the eggs to the dish without breaking the yolks or making a mess in the pan.  Simply crack one egg into a cup and slip the egg into the well of veggies in the skillet.  Repeat this with all the eggs.
  • Runny eggs vs. more cooked.  Do you like a runnier egg?  I find that baking the eggs for 7 minutes at 400 degrees gave me perfectly runny eggs, but all ovens are different.  If you want the eggs more cooked, I suggest baking them for 10 minutes.
  • Make for a crowd!  This dish is great for a crowd because it is so easy to prepare.  I recommend doubling the whole recipe and using a large sheet pain to ensure all the veggies and eggs have enough space and cook evenly.

Prepping and Storage

Leftovers will keep in the fridge for about 3 days in sealed, airtight containers, but make sure the eggs and vegetables have cooled completely before storing.  When ready to reheat, simply warm this up in a skillet on the stove or reheat in the microwave until heated through.
