Preheat oven to 170C. Grease and line a baking dish (approx 30cm x 20cm).

Add cream to eggs and beat lightly. Add onion, bacon, the two cheeses and grated zucchini to the egg mixture and mix through. Season the mixture with salt and ground black pepper. Add flour and mix through thoroughly.

Pour into lined baking dish and top with additional grated tasty cheese. Cover the top with a sheet of baking paper and remove this paper after 30 mins. Bake for 40 – 45 mins until set. Allow to sit and cool slightly before cutting.
