18+ High Protein Breakfast Casseroles (>20G protein)

Who doesn’t love a breakfast casserole? Most often, they’re quick to throw together with plenty of leftovers. I’ve assembled 18+ high protein breakfast casseroles (with at least 20 grams of protein) to make life a littler easier – and provide a delicious and filling breakfast.

It’s hard to assemble a breakfast high in protein in the morning – especially with little ones involved! These recipes are the epitome of what this site stands for: prioritizing more home-cooked meals in an easy, accessible way.

The one downfall of casseroles is they tend to be higher in sodium. Though, in my opinion, the pros definitely outweigh the cons. There is so much to love about a breakfast casserole!

  • Bake it once, and eat it all week long!
  • Portions large enough to feed a crowd (or your entire family).
  • Easy meal prep – leftovers can even be frozen for a quick and easy breakfast on busy mornings.
  • These recipes are filling and satisfying – with at least 20 grams of protein per serving! If you’re trying to follow a higher protein diet – breakfast is often the hardest meal to prepare.
  • Adds some variety to your typical breakfast and often easier than making eggs, bacon, potatoes, etc. separately.

Customizing Casseroles to Increase Protein and Fiber

Both protein and fiber help to prevent blood sugar spikes and keep us fuller for a longer period of time.

Increase the protein content of a casserole by incorporating cottage cheese, Greek yogurt, nutritional yeast, lean sausage, quinoa, tofu, edamame, or nuts. Sprinkle hemp hearts on top for omega-3 fatty acids and extra protein.

Cheese, a staple for most breakfast casseroles, is also a good source of protein.

Beans and legumes add extra protein AND fiber! Select fruits and vegetables that are high in fiber like pears, raspberries, peas, broccoli, collard greens and cauliflower.


I hope this post inspires you to make more breakfast casseroles – on Sundays, for holidays, or whenever you don’t want to plan your breakfast all week long.

Sometimes, just a little bit of preparation and planning can go a long way as a busy mom! Even when it feels like a lot of work.
