Grease or line a muffin tray with 8 slots. If you don’t have a muffin tray, you can cook this in a regular baking dish and slice it to portions at the end.
Melt butter in the frypan then add mushroom and onion, cooking until caramelised.
Take frying pan off the heat and add in herbs, capsicum, salt and pepper.
Crack the eggs into a small small bowl and whisk until combined.
Whisk the cream into the eggs and season with salt and pepper.
Evenly divide the fried mixture into slots of your greased muffin tray.
Add in a generous amount of grated cheese to each.
Fill each muffin slot with egg mixture and top with remaining cheese.
Bake in the oven for roughly 10-15 minutes, until the eggs are firm but not too hard. The cooking time may vary according to the depth of your muffin tray.
Serve hot or cold.
