Egg Frittata with mayonnaise

The Ultimate Keto and Paleo caramelised onion Frittata

Giant one pan Omelete that is Gluten-free, Refined Sugar-Free and Low Carb for at-home freezing.

We understand that batch cooking can save so much time! It is also a great way to ensure you always have something quick and easy to reheat to avoid snacking on sugary foods that jump on you in the queue for the petrol station, supermarket, corner shop, and even in some clothes stores now! What's that about - chocolate or sweets at the tills - yikes!

This one-pan frittata recipe is perfect for lunches, dinners or snacks on the go. It can also be reheated or eaten cold for a filling low carb snack on the go. 


What is a Frittata and how can you ensure it is suitable for the Keto diet?

A frittata is an egg-based dish that comes from Italy. It is similar to a spanish omelet however it does not contain potato. A frittata is normally deeper than an omelet and has added ingredients like meats, cheese or vegetables. 

If making your own at home, you can also experiment with adding keto-friendly meats (choose grass-fed/pasture for life where possible), low carb veggies and cheese (to increase the fat content). 

If shopping for a premade frittata be sure to check the ingredients for added refined sugars, seed/vegetable oils or high carb vegetables like white potato.


What is the best pan to use for making Keto Frittatas?

We recommend that you use a metal skillet pan, that can also be used in the oven. We keep our pans in top condition by oiling the pans with avocado oil, tallow or animal fats before use. 


Can you freeze a homemade frittata?

Yes, you can freeze this recipe. We recommend cutting into snack size pieces first (especially for young children) and you can pop them in your lunch bag frozen and they will have fully thawed by the time you get to lunch, whilst also helping to keep the rest of your food cool at the same time. 


What eggs should I use when making an omelet or this Keto recipe?

We are big fans of St Ewe Eggs and they are what we use solely in our Egg-based mayos. They are British Free Range eggs from happy, healthy hens. We would recommend Red Lion approved eggs from Organic or Free Range farms.
