Two Potato Gratin (Microwave) - cooking recipe

Ingredients

1 1/4 lbs russet potatoes, peeled and thinly sliced (about 2 large)
2 teaspoons dried rosemary (rubbed between fingers to release the flavors, or use 1 tbsp fresh finely chopped)
1 1/4 lbs sweet potatoes, peeled and thinly sliced (2 medium potatoes)
1 1/2 cups whipping cream (unwhipped)
1 1/2 cups swiss cheese
1/2 cup parmesan cheese
salt and black pepper (I use seasoning salt)

Preparation

Butter a 8 x 8-inch microwave-safe baking dish.
Arrang HALF of the sliced russets in the baking dish; season with salt and pepper.
Sprinkle about 1/4 of the dried rosemary over the russets.
Top with HALF of the sweet potato slices, then season with salt and pepper, then sprinkle with 1/4 of the the rosemary.
Repeat layering with russets and sweet potatoes, seasoning each layer with salt and pepper and 1/4 rosemary.
Pour/drizzle the whipping cream over.
Cover tightly with heavy microwave plastic wrap.
Microwave on HIGH until the potatoes are tender (about 18-20 minutes).
Remove and sprinkle BOTH cheeses over the potatoes.
Return to the microwave uncovered on HIGH for about 3 minutes, or until the cheese has melted.
Cool 10-15 minutes before serving.
