Preheat oven to 350 F. Lightly grease 9x13 baking dish.

Place the potatoes in a large microwave-safe bowl and add 1 cup of water. Cover and microwave 7 minutes or until the potatoes are tender.

Drain potatoes. Spread half of them in the bottom of the baking dish. Combine garlic and 1/2 cup parmesan cheese. Spread over potatoes. Sprinkle with browned sausage.

Whisk together the eggs, milk, yogurt and 1/2 cup Parmesan cheese. Season with salt and pepper. Pour half of mixture over sausage.

Lay the rest of the potatoes on top. Pour the rest of the egg mixture over the potatoes and top with remaining 1/4 cup of Parmesan cheese. Bake uncovered for 50-60 minutes until the egg is puffed and golden around the edges. Sprinkle with basil. Cool for 5-10 minutes before serving.
