Keto diet list of our main ingredients 

Studies proved that if you make breakfast the largest meal of the day, you are more likely to have a lower BDI (body mass index) ! (source)

This is the list of your most common ingredients with tips on how to prepare them.


Eggs are so versatile which make them superfoods that are good addition to ketogenic diet because they are nutrient-dense loaded with high protein, good fat, essential minerals and fairly low carbs. 

One good thing about eggs is the many ways that you can do with them in your keto diet; keto snack, breakfast as either; scrambled, fried, boiled, poached. Moreover, eggs make a fantastic, moist binder for meatballs, casseroles, etc. 


And for a fantastic, scrumptious and fluffiest eggs imaginable, add some heavy whipping cream. Make a light and airy eggs that are also rich and savory by scrambling the whipping cream and the eggs together. 


This is where all the creativity is manifested. There are a number of meat product that can be viable to add to your casserole;

  • Bacon
  • Sausage
  • Ham
  • Ground beef
  • Turkey

The goal is to use the meat that can mix and bind well with the ingredients. The meat will need to be pre-cooked before it can be added to the casserole ingredients. 


Adding vegetables to your casserole is both healthy and great for flavor. Moreover, vegetables are more filling because of the high fiber or roughage which is excellent for weight management. Like meat choices, these will also need a pre-cooking however you prefer; steam, pan fry, or roast before they are added into the casserole. 

Adding broccoli and cauliflower in your healthy casserole is the best option. You have to be careful to prepare the veggies in a way that get the moisture out of the veggies especially water based veggies like tomatoes and zucchinis. 


Any hard cheese will do for delicious casseroles. We avoid processed chasse as much as possible.

Before baking

  • after following all the instruction on making the casserole, you skip the part about baking it. 
  • Using a plastic wrap, cover the casserole.
  • Then cover it with a foil and then place it in a freezer. 
  • Too refreeze it, you simply move it from the freezer to the fridge allowing it to thaw overnight. 
  • Then put it in a room temperature the following day and then bake it for 35 of 40 minutes or until it is completely baked.  

After baking

  • You have an option of portioning it or freezing the whole bunch of leftover. 
  •  Allow the well-cooked casserole to sit in a room temperature to allow it to cool completely. 
  • Place the low carb breakfast casserole on a cooling rack and let it cool completely to room temperature. 
  • Let the casserole be covered with a plastic wrap and then a foil on top to place it in a freezer. 
  • Let it stay in the fridge overnight to thaw.
  • After a couple of hours, unwrap it and cover lightly. 
  • Then let your casserole finish thawing in the fridge to let the condensation evaporate to prevent the casserole from getting soggy.
