  • 6 slices bacon chopped (130g)
  • 5 ounces mushrooms or 150 grams
  • 2 tbsp butter
  • 1/2 tsp dried thyme (or 3-4 sprigs thyme)
  • 1/4 tsp black pepper cracked (or to taste)
  • salt (to taste) Optional
  • 1 ounce onion or (35g)
  • 1/4 cup parmesan grated (15g)

White Sauce

  • 1/2 cup mozzarella cheese grated (or cheddar cheese) (57g)
  • 1 tbsp water

Optional Flavorings

  • salt and pepper
  • 1/2 tsp paprika (or chili flakes)
  • 4 tbsp herbs (of choice) (freshly chopped)

Instructions

  • Preheat the oven to 400F / 200C / 180 fan.
  • Place green beans, salt, olive oil and garlic on baking tray and roast for about 20 minutes until soft.
  • Add the bacon to nonstick large skillet. Sauté for 2.5 minutes on a medium heat then add the mushrooms, 1 tbsp butter and thyme leaves. Sauté for 2.5 minutes. Season with pepper and optional salt to taste.
  • Fry onions in 1 tbsp of butter until soft, about 2 minutes. (Option to sauté with the mushrooms if you prefer and add the extra butter.)

White Sauce

  • Add the cream cheese, butter and heavy whipping cream to a clean large saucepan over a low heat. Whisk with a balloon whisk until melted.
  • Add the cheese and whisk until fully melted. Thin with about 1 tbsp of water. Season with salt and pepper and any additional flavorings you may wish to add.
  • Remove the skins from the roasted garlic and mince using a garlic press or chop and stir through the sauce.
  • Arrange the green beans and bacon / mushroom sauce/ onion mix in a baking casserole dish. Pour the white creamy sauce (don’t worry it gets more saucy as it cooks!) over the green bean mixture. Top with parmesan cheese.
  • Cover baking dish with foil and bake for 20 minutes. Uncover and cook for a further 15 minutes or until golden brown on top of the casserole.
  • Storage: Fridge in a Tupperware for up to 3 days.
