One Pan Breakfast Casserole Even Your Teen Can Meal Prep!

1 small onion diced
1 medium bell pepper diced
1 head of broccoli chopped small
4 cloves of garlic minced (or a good 2-3 tsp garlic powder)
12 eggs we use pasture raised eggs
½ cup milk of choice we use coconut milk but any milk will work
1 cup cheese of choice shredded & divided
1 teaspoon sea salt
½ tsp pepper
½ tsp dried thyme
2 tbsp butter ghee, avocado oil, or olive oil
1 lb ground sausage of choice optional if you like meat on the side or don’t have available

Pre-heat the oven to 375 degrees. If your teen is making this dish, I usually suggest for teens to prep all of the ingredients first, so it is all ready to go – I’ll explain how my teen did it that way here!
Chop all of the veggies, and shred the cheese first so it’s ready to go. Before cooking, whisk the eggs, milk, ½ cup of the cheese, salt, pepper, & thyme in a medium mixing bowl and set aside.
In a stovetop & oven safe casserole dish, melt 2 tablespoons of butter, and brown the sausage.
Once the sausage is browned, add the onion, pepper, broccoli, and garlic, stir, and cook for 2-3 minutes over medium/high heat. If your pan doesn't have a lot of fat left from the sausage, you can add a tablespoon of butter to the bottom to keep everything from sticking before pouring the egg mixture in.
Pour the egg mixture into the casserole dish, stir the veggies and meat into the egg mixture, and bake uncovered at 375 degrees for 40 minutes. Let the egg casserole cool for 5 minutes before cutting.
To store and reheat the egg squares, I like to use an air-tight container to store in the fridge, and in the morning your teen can either eat the square cold, or if they want it warmed, up they can pop it on a sheet tray into a cold oven and pre-heat to 350 degrees – this will gently warm it up to a hot temperature.

If you do not have a stovetop & oven safe casserole dish, you'll just have to use a skillet to brown the meat and cook the veggies, and then transfer the egg mixture and meat/veg to your casserole dish. It means an extra pan to clean, which is why I tend to have my teen use my one pan method so she doesn't have extra pans to clean!
We use a sheep’s milk Manchego for this recipe, but cow’s milk cheeses OR if you are dairy free the Voila Life coconut-based cheeses are great! You could also leave this ingredient out if you don't tolerate the dairy or non-dairy alternatives.
There are a lot of sausage options. Best choice would be something pasture raised, but that is not always available for everyone. I do tend to use our ground beef meat from the grass-fed cow that we get every year, and season that with my sausage season blend. Next best choice would be to use a ground turkey or pork sausage that has minimal ingredients and no fillers/MSG, etc. The Jenny-O turkey sausage and Swaggerty's pork sausage are something we use sometimes where I live.
Kids not a broccoli fan? Swap it for spinach, or leave it out. You can swap the peppers for shredded carrot too. If it means them eating it more willingly, either back off on the amount of the veg (and chop it super fine), or just leave it out. I'd rather them actually eat it than grab for a bowl of cereal!
