Step 1

Bring a large pot of lightly salted water to a boil. Add the zucchini and cook until just tender, about 4 minutes. Drain well in a colander.

Step 2

Preheat the oven to 350F. Grease a 9-inch round or 8-inch square ceramic baking dish. Spread the zucchini in the pan and dot with pieces of butter.

Step 3

In a large bowl, whisk together the eggs and cream. Stir in the onions, salt, and pepper, and half of the cheddar cheese. Pour over the zucchini.

Step 4

Sprinkle the top with the remaining cheddar, the parmesan, and the pork rinds. Bake 35 minutes, until bubbly and the edges are nicely browned. Sprinkle with chopped basil, if desired.
