How to make a delicious breakfast casserole with simple ingredients.

Quick & Easy Breakfast Casserole

I absolutely love breakfast casseroles, frittatas, scrambles, you name it. What could be better than a one-pot breakfast dish with your favorite fillings? It’s easy, usually quick, and uses up anything in your fridge that needs to go. The best thing about them is that you can put almost anything inside them. Your favorite protein, vegetables, fresh herbs, and cheese, if you wish. This can be as healthy as you’d like it to be. You don’t even need to use potatoes or cheese if you don’t eat them, making this paleo or keto.

This is a great way to use up any vegetables or proteins in your fridge that may not have much life left. You can call it a sink casserole, if you will. Themes are great too – make it Mediterranean, Mexican, Italian, or even Indian in flavor.

Get Creative

The other great thing about this breakfast casserole is that you don’t necessarily need to follow the recipe. Use the base, which is eggs and potatoes, and get creative! These can be eaten for breakfast, lunch or dinner. Alongside a green salad, vegetables, bread, or protein can round this out to a complete meal, too. I usually just eat it alone.

Again, if you want to keep this recipe keto, omit the potatoes and add more eggs or vegetables. You can also keep the recipe paleo by leaving out the cheese. These breakfast casseroles really fit into any diet, except egg-free!

Eggs and Herbs
