These frittata muffins are a handy way to get a proper breakfast, even on busy mornings. They’re packed with fresh veg and tangy feta cheese, making each bite both filling and flavourful.
The recipe is really simple – just whisk your eggs with milk and seasonings, then layer in the spinach, tomatoes, spring onions and feta. The mustard adds a kick that works well with the salty cheese, while the garlic brings everything together.
What I love about these is how versatile they are. They’re great straight from the oven when the edges are slightly crispy, but they’re just as nice cold for lunch the next day. You can make a batch on Sunday evening and have breakfast sorted for most of the week.
They’re not fussy at all – if you’ve got different vegetables in the fridge that need using up, throw them in instead. Just make sure anything wet like mushrooms or courgette is cooked first to avoid soggy muffins.
The key to success is greasing your tin well and not overfilling the holes. Give them five minutes to cool slightly before taking them out, and they’ll pop right out without sticking. Perfect!
