Preheat the oven to 180 degrees Celsius. Add some oil to a hot pan, add in the diced onion and fry until translucent. Add the mince and the seasoning and fry until brown.
Add the marmite and some water to dilute. Simmer for a few minutes before adding in the cream and cream cheese. Let it simmer for a few minutes, add the cooked macaroni noodles and mix well. Scoop into your baking dish of choice.
Add 2-3 cups of the grated cheese and some breadcrumbs on top and place in the oven to bake for 15-20 minutes.
Remove to cool slightly and serve.
