Breakfast Casserole Healthy Substitutions
Olive Oil: You can substitute olive oil with avocado oil or melted butter.
Veggies: Feel free to add more veggies. Spinach or other greens would be great in this casserole.
Eggs: You can add in egg whites if you’d like a higher protein/lower fat option.
Spices: You can add more spices if you’d like or substitute in fresh herbs. For fresh herbs use double the amount compared to dried herbs.
Cheddar Cheese: Feel free to omit cheese from this recipe to make it dairy free. You can also substitute other cheese. We think pepper jack, Monterey jack, shredded mozzarella would all work well.
To Make it Lower Carb: Use lower carb vegetables.
Spices: You can use more or less dried spices. Feel free to mix in whatever spices you like!
To Make it Lower Calorie: To save calories, you can spray your pan with olive oil instead of pouring it into the pan. You can also use half the amount of cheese or skip the cheese.
Can I use almond milk in egg bake? This recipe doesn’t have any milk in it but you definitely can add 1/4 cup to make it creamier. Almond milk will work.
WW Points: Will vary depending on the plan you follow. Olive Oil: 3SP, cheese: 16SP. Total points: 19/4= 5 points per serving. You can save points by using low fat cheese. Low fat cheese reduces this to 2 points per serving.

Made exactly as the recipe stated and it was perfect! Hearty without being too heavy and just a perfect lazy weekend meal. I love how you could easily swap out the veggie choices for whatever you like. Excellent recipe!

I served this on Easter Sunday morning, and my family really enjoyed it. I chopped all the veggies the day before to make things easier on Easter morning. Instead of using pre-packaged cheddar cheese which has cellulose in it, I quickly shredded my own cheddar from a block using a microplane. We were able to quickly re-heat leftovers in the microwave for a few days. I will definitely be making this again. Thanks for the recipe.
