- 1-2 long sweet potatoes (about 2 inches thick), peeled

- Salt and pepper to taste
How to Make Cheesy Root Vegetable Gratin
Step 1: Preheat the Oven
Preheat your oven to 400˚F. Grease a 3-quart baking dish with softened butter to prevent sticking.
Step 2: Prepare the Vegetables
- Slice sweet potatoes, parsnips, and beets into very thin rounds using a mandoline slicer for best results.
- Transfer each type of vegetable into its own mixing bowl.
Step 3: Season Each Vegetable
- Pour 4 tablespoons of cream over each bowl of sweet potatoes and parsnips. Use 2 tablespoons of cream for the beets.
- Top each bowl with ½ ounce of grated Parmesan and 1 teaspoon of minced thyme.
- Generously season each bowl with salt and pepper. Toss until all slices are well coated.
Step 4: Layer the Gratin
- Pour remaining ¼ cup cream into the bottom of your greased baking dish. Sprinkle with ½ ounce of Parmesan cheese and add minced garlic.
- Create layers by standing sweet potato slices up at one end of the baking dish. Follow with a row of parsnips and then a row of beets. Repeat until all vegetables are used.
Step 5: Bake Covered
Season the top layer with salt, pepper, and remaining Parmesan cheese. Cover the dish with foil and bake for 30 minutes or until the vegetables are soft.
Step 6: Add Cheese Topping
Uncover the gratin, sprinkle shredded gruyere on top, then return it to the oven uncovered. Bake for an additional 18 to 20 minutes until fork-tender and golden brown on top.

How to Perfect Cheesy Root Vegetable Gratin

- Slice evenly: Thin, uniform slices allow for even cooking and better presentation.
- Layer wisely: Alternate the layers of vegetables for a colorful and visually appealing dish.
- Season generously: Don’t shy away from seasoning each layer; this builds depth in flavor.
- Watch the baking time: Overbaking can lead to mushy vegetables, so check them after 30 minutes.
- Let it rest: Allowing the gratin to sit for a few minutes before serving helps set the layers and makes it easier to slice.

Common Mistakes to Avoid
Avoiding common mistakes can make your Cheesy Root Vegetable Gratin even more delicious. Here are some pitfalls to watch for:
- Overcrowding the baking dish: If you cram too many vegetables in, they won’t cook evenly. Arrange them neatly in rows for the best results.
- Neglecting to slice vegetables evenly: Uneven slices can lead to inconsistent cooking. Use a mandoline for uniform thinness.
- Skipping seasoning: Seasoning each layer of vegetables is crucial. Don’t forget to add salt and pepper at every step for maximum flavor.
- Using low-fat cream: Low-fat cream won’t yield the same creamy texture. Stick with heavy cream or whole milk for best results.
- Not letting it rest before serving: Allowing the gratin to sit for a few minutes helps set the layers. This prevents it from falling apart when served.
