This caramelized onions and kale frittata is so tasty. Make it for Brunch or if you have guests over and they are sure to love it. Not only the quiche is easy to make, which allows you to not have to be next to your stove the entire time and be with your guests or family, but the quiche is also extremely flavourful and satisfying, which makes it totally worth doing. It’s also colorful with the addition of kale. It’s a great recipe to make all year long.
What’s the Difference between Quiche and Frittata?
Quiches have a crust and usually contain cream or milk. Frittatas, on the other hand, are crustless and contain little or no milk or cream. They are usually cooked in a skillet but can be baked too. Frittatas are healthier.
To make the frittata, you will first want to caramelize some onions into a deep pot with a little olive oil. Caramelization is the browning of sugar. It’s to achieve the nutty flavour and brown colour. As you will cook them, on medium heat, you will need to deglaze your pot from time to time by simply adding a little water to the pot and keep stirring to avoid that the bottom of your pot burns. It’s the longest process in making the quiche. You will need to stay in the kitchen nearby. You don’t want the onions to burn – You just want them very soft and with a brown color. This process can take a good 15 minutes to do but it’s totally worth it. It really adds a nice flavour to the quiche while adding a natural touch of sweetness which pairs beautifully with the bitterness of the kale.
What Kind of Kale?
I used the curly type of kale – Not the lacinato kale, aka dinosaur kale. You want to purchase organic kale if possible as it does contain a lot of pesticides unfortunately. Then you remove the stems and torn the leaves in small pieces. You cook them in olive oil too, possibly in the same pot as the onions but when they are close from being done. The kale is quick to cook. It will take about 2-3 minutes. You just want to soften it and brighten up the green colour.
Optional Add In
The quiche is dairy-free but a nice addition but would be a good quality cheese. I would probably go with some fresh goat cheese, Gruyère or a sharp cheddar. The cheese you can add it in the batter with the eggs or add it on top of the quiche before baking.
How to Do it
Place your cooked veggies first in the pan.
Cover with egg mixture. Add cheese on top if desired. Bake.
Serve Hot or Cold?
A frittata can be served hot, cold or room temperature. I would say it depends on when you are serving it and the occasion. I prefer it warm personally though.
What to Serve With
Anything from a crunchy salad or spinach salad with nuts or seeds, some grilled sandwiches or paninis, boards with cheeses, fruits, nuts and cold cuts, a smoked salmon, red onions and caper platter, … So many choices, depends what you’re in the mood for and what your family or guests like.
