Prep your green beans if they are fresh by rinsing and cutting off ends. If frozen thaw them.
Keep a pot to boil with water and salt. Place green beans into boiling water and blanch (cook for short time) for about 5 minutes.
Take out green beans and place them into ice water to stop the cooking process and to help retain the green color. Keep aside
Preheat oven to 400° F./ 200° C.
Prepare the filling in a bowl. Combine eggs, cream, dijon mustard, salt, black pepper, Italian seasoning, and half quantity of the cheese together.
Spread green beans in a casserole dish and pour filling over the green beans.
Sprinkle remaining cheese over the green beans in the casserole and the olive oil
Bake at 400° F./ 200° C for 20-15 mins until golden.
Serve hot

Notes
You can choose to use fresh green beans, frozen or canned beans.
I used heavy cream in the video recipe, you can use table cream too
I used a blend of cheddar and parmesan. You can use whatever cheese you like. Use half of the quantity for the cream egg blend and the other half to top the green bean casserole.
