Preheat your oven: to 180°C / 350-375°F / Gas Mark 4-5.
Zucchini: trim the top and base of the zucchini and then use your food processor to thinly slice. Once done, transfer to large mixing bowl.
Seasoning: add the diced bacon, parmesan cheese, garlic powder, onion powder, salt, pepper and stir to combine. Then reserve some of the combined mixture by transferring it to a small bowl.
Slice tray: line a slice tray with baking paper and then transfer in the seasoned zucchini bacon mixture. Spread this out so that it is in an even layer and all of the pieces face upwards.
Eggs: crack the eggs into a medium sized mixing jug and then use a fork to whisk them.
Cream and cheese: pour the cream into the whisked eggs, followed by the cheese and stir until thoroughly mixed together.
Egg mix: pour the wet egg mixture over the seasoned zucchini and bacon. Then gently tap the tray to remove any bubbles. Decorate the top of the frittata with the reserved pieces bacon zucchini mix.
Oven bake: place the slice into the oven on the middle shelf and bake for 30 -35 minutes. Use oven mits to remove the slice when cooked and place it onto a heatproof surface.
To serve: allow the slice to cool for a couple of minutes before lifting it out of the slice tray using the baking paper and setting it onto a chopping board. Then take a sharp knife and cut it into uniform sized pieces. Sprinkle some finely chopped chives over the top and serve with mustard yogurt sauce (optional). Notes 5 and 6.
