4 tablespoons butter
4 large zucchini, sliced
4 medium shallots, minced
2 teaspoons garlic, minced
1 cup heavy cream
2/3 cup cheddar cheese
1/3 cup Parmesan cheese
1/4 teaspoon oregano
Salt and pepper to taste
Green onions, sliced
Preheat the oven for 400 degrees F.
Heat a large, deep pot to medium heat and add the butter. Once melted, sauté the shallots and garlic in the butter until the shallots are translucent – about a minute or two.
Add the zucchini, heavy cream, salt, pepper, oregano, and Parmesan cheese. Let the mixture cook on the stovetop for about 8 to 10 minutes, until the mixture is bubbly.
Transfer to a greased 9X13 casserole dish and mix in most of the cheddar cheese – once everything is blended thoroughly, sprinkle the rest of the cheddar cheese on top.
Bake the gratin for 10 to 14 minutes, or until the cheese is bubbly and golden-brown. Top with sliced green onions
