Take to a Gathering or Holiday Breakfast
Everyone loves breakfast casseroles and there are so many variations that people take to gatherings. I love to be the one bringing healthier options to those parties where most other dishes are less healthy indulgiences. Also, if you’re looking for something to bring to a party of health conscious friends, this is a great option!
Breakfast Casserole Ingredients:
Potatoes: I used simple red potatoes for this recipe but any potatoes should work. Just wash and grate the potatoes and you don’t have to worry about peeling them. I also give an option for frozen hashbrowns in the recipe.
Avocado oil: This neutral oil has a high smoke point so it’s my choice for cooking. You can always substitute olive oil or butter if you’re alright using dairy.
Sea salt: You can definitely adjust the amount used in this recipe according to your preference.
Garlic cloves: I love using fresh garlic but you can also use 2 teaspoons of garlic powder.
Onion: This veggie brings flavor and an amazing texture to our casserole. I don’t reccomend replacing this ingredient.
Mushrooms: Adds flavor and more texture to the casserole. If you want to leave the mushrooms out, I reccomend replacing them with another veggie like fresh tomatoes.
Bell pepper: You can use any color of bell pepper in this recipe or a mixture of multiple colors.
Spinach: There is 2 cups of spinach in this recipe but when it wilts, it becomes much smaller. You can always leave this ingredient out if you like.
Eggs: The star of the show in this casserole! You’ll be using 8 large eggs for this recipe.
Full fat coconut milk: There’s so little in this recipe that you can’t taste the coconut at all, but you can always substitute dairy cream if you want.
Cheddar cheese: I decided to include the cheese because it really levels up this recipe! This ingredient is completely optional and you can always substitute a dairy free alternative or 1 tablespoon of nutritional yeast for cheesy flavor.
Equipment You’ll Need
- You need a basic cheese grater to grate the potatoes. Something simple like this one will work great!
- I love using glass mixing bowls because they last so long and are ideal for healthy cooking. Here’s a glass mixing bowl with a lid that can be used for so many different recipes.
- I got my casserole dish as a gift but here’s another white ceramic 9×9 dish you could use for this casserole!
