Melt half the butter in a saucepan over a low/medium heat. Thinly slice the garlic and shallot and add to the pan. Sweat gently for a minute or so until tender. Add the cream cheese and stir until melted.
Step 2
Add the cheddar, heavy cream, parmesan, brie, salt and pepper and stir well. Simmer until heated through and the cheeses have melted together to form a thickened sauce.
Step 3
Slice the ends from the zucchini and peel away the skin. Peel the zucchini flesh into wide ribbons. Melt the remaining butter in a skillet over a low/medium heat and add the zucchini, cooking for a minute or two until just tender.
Step 4
Spoon the sauce over the zucchini and stir well to coat. Serve hot.
