- salt and fresh ground black pepper, to taste (I add about 1 teaspoon of salt and 1/2 teaspoon black pepper)
- ½ teaspoon dried thyme
- ½ teaspoon dried rosemary

Instructions
- Preheat oven to 350˚F.
- Lightly grease a 9-inch baking dish with butter or cooking spray and set aside.

- Arrange one layer of sliced sweet potatoes, overlapping slightly, on the bottom of the baking dish.
- Sprinkle with a bit of parmesan and pour about 1/4 cup of evaporated milk.
- Repeat layers with remaining sweet potatoes, parmesan, and milk.
- Top with swiss or gruyere cheese.
- Cover with foil and bake for 35 minutes.

- Remove from oven and let cool for 10 minutes.
- Garnish with grated parmesan and dried parsley.
- Serve.
Notes
- Sweet Potato Slices: Cut the slices to the same thickness for even cooking.
- Layering: Slightly overlap the sweet potato slices. This not only looks nice but ensures each bite is seasoned and flavored.
- Season Every Layer: Sprinkle each layer of sweet potatoes with a bit of the seasoning mix.
- Cheese Choices: Use different cheeses for varied flavors.
- Crunchy Topping: For some crunch, add a breadcrumb mix on top during the last few minutes of baking.
- Pre-Cooking Sweet Potatoes: If you're short on time, parboil the sweet potato slices for a few minutes before baking. This reduces the overall cooking time in the oven.
- Herb Variations: While thyme is classic, sage can also complement sweet potatoes.
- Creamier Sauce: You can use heavy cream for an even creamier texture.
- Spice It Up: Add a pinch of cayenne pepper to the spice mix.
- Let it Rest: Allowing the gratin to rest for 10 to 15 minutes after baking helps the layers settle and makes it easier to serve.
