1/3 cup plain flour
2 1/2 cups milk
1 1/4 cups grated cheddar cheese

10 eggs
300ml thickened cream
3/4 cup chopped fresh flat-leaf parsley
8 middle rashers bacon, trimmed and chopped
250g cherry tomatoes, halved

1. Preheat oven to 200 degrees celcius fan-forced.  Grease a 5cm deep, 24 x 34 baking dish.  Line base and 2 long sides with baking paper, allowing a 2cm overhang.

4. Remove from heat.  Gradually add 2 cups milk, whisking constantly until  smooth. 
5. Return to heat.  Add cheese and nutmeg.  Cook, stirring, for 10 minutes or until sauce thickens. 
6. Remove from heat.  Cool for 10 minutes.  Discard bay leaves.
7. Whisk eggs, cream and remaining milk together in a bowl.  Add parsley and cheese mixture.  Season with salt and pepper.  Stir to combine.  Pour into prepared dish.  Cover with foil.  Bake for 40 minutes or until edges start to set.
8. Meanwhile, heat a non-stick frying pan over medium heat.  Cook bacon for 3-4 minutes or until just golden.
9. Remove foil from baking dish.  Top frittata with bacon and tomato.  Bake 25-30 minutes or until just set in centre.  (Re-cover with foil if starting to burn.)
