This crustless quiche is grain-free, nut-free, vegetarian and keto. Make a batch to have lunches and breakfast sorted for a week!

What is the difference between a frittata and a crustless quiche, I hear you ask? The main difference is that a frittata is traditionally started off on the stovetop and then transferred to the oven to complete cooking.

That’s well and good, but who has time for that? A crustless quiche goes together in one ovenproof dish and is then baked in the oven.

The other difference is that compared to a typical frittata, this crustless keto quiche contains more cream and cheese which means more flavour!

You can use this basic recipe to make any variation that you like. I make at least one per week to slice up for lunches and breakfasts. Feel free to substitute the spinach with chopped broccoli, cauliflower or even zucchini. You can also use smoked salmon, sliced bacon or chicken.

You can freeze the portions as long as they are well wrapped and you let them thaw naturally. Enjoy!

I liked the look of this dish, and just happened to have all of the ingredients ( which is unheard of for me, ha). It was quick and easy to make, and after the 45 minutes were up, I was so happy, as it looked just like your photo ( again, unheard of for me). This was so delicious, my family were fighting over who had the biggest slice! This is an absolute keeper, thanks so much .

Thank you so much for your lovely feedback, I'm glad you all enjoyed!
