Eggs, sweet caramelized onions, browned shredded potatoes and hearty kale – how can you go wrong with this kale onion potato frittata? This is a comfort food kind of dish. And it could be breakfast, lunch, dinner or all three, although it doesn’t tend to stay around long enough for all that! Three of us had it for dinner and my daughter happily took the rest for lunch the next day. The potatoes are key to the comfort factor, but the sweet caramelized onions, earthy kale and protein-rich eggs really round it out and make it a meal. You can’t really tell there’s Dijon mustard in there but it gives the frittata a subtle tanginess and the cayenne pepper adds a gentle heat.
Make this kale onion potato frittata stress-free!
It doesn’t take long to shred the potatoes on a grater, but if you like you could substitute frozen shredded hash browns and just cook according to the instructions on the package. You could also prepare the frittata through the point where you add the eggs and refrigerate it overnight. Then bake before mealtime – the frittata will take longer to cook being cold from the fridge but just bake until the eggs are set.
This kale onion potato frittata would make an attractive and satisfying brunch offering or a great simple supper!
