Ingredients

• Sweet Potatoes: These provide a naturally sweet flavor and creamy texture when baked, perfect for balancing the richness of the cheese.
• Parsnips: These add a slightly nutty and sweet taste, which complements the sweet potatoes and beets in the gratin.
• Beets: Beets contribute an earthy flavor and vibrant color to the dish. They are rich in fiber and antioxidants.
• Heavy Cream: Cream creates the rich, velvety texture that binds the vegetables together and helps the cheese melt beautifully.
• Parmesan: Grated Parmesan adds a salty, savory depth that enhances the overall flavor of the gratin.
• Fresh Thyme: This herb infuses the gratin with a subtle, earthy fragrance, elevating the dish’s complexity.
• Garlic: Minced garlic adds a sharp, savory punch, complementing the sweetness of the root vegetables.
• Gruyère: Shredded Gruyère provides a creamy, nutty flavor that perfectly melts over the top of the gratin.
• Salt and Pepper: These seasonings enhance all the flavors in the dish and allow the natural sweetness of the vegetables to shine through.

Alternative Ingredient Suggestions

• For a lighter version, swap the heavy cream for whole milk, though the texture may be slightly less creamy.
• You can substitute the Gruyère with another melty cheese, such as mozzarella or cheddar, depending on your preference.
• If you’re looking to make this dish dairy-free, try using coconut cream and a dairy-free cheese alternative for a similar richness.

Step-by-Step Instructions

1. Preheat the oven to 400˚F and grease a 3-quart baking dish with butter.
2. Slice the sweet potatoes, parsnips, and beets into very thin rounds. A mandoline works best for uniform slices.
3. Divide the vegetables into three separate bowls. Pour 4 tablespoons of cream over the sweet potatoes and parsnips, and 2 tablespoons of cream over the beets.
4. Top each bowl with ½ ounce of grated Parmesan and 1 teaspoon of minced thyme. Season generously with salt and pepper and toss until the vegetables are well coated.
5. Pour the remaining 1/4 cup of cream into the bottom of the greased baking dish and sprinkle with ½ ounce of Parmesan and minced garlic.
6. Arrange the sweet potatoes in the baking dish, standing them up on a slight bias. Follow with the parsnips and then the beets. Repeat until all vegetables are used, creating six rows of vegetables.
7. Season the top with salt, pepper, and a final sprinkle of Parmesan.
8. Cover the dish with foil and bake for 30 minutes or until the vegetables are soft.
9. Uncover the gratin, top with shredded Gruyère, and bake for an additional 18 to 20 minutes, or until the cheese is melted and golden.
10. Finish with a sprinkle of fresh thyme leaves. Serve hot and enjoy!

Tips & Tricks

• Make sure to slice the vegetables thinly for even cooking. Using a mandoline ensures consistent slices.
• If you’re preparing this dish ahead of time, you can assemble it the day before and refrigerate it. Just add 5–7 extra minutes of baking time when you’re ready to cook.
• To avoid the beets bleeding into the cream, coat them lightly in cream and ensure a thin layer of cream in the bottom of the baking dish.
• If you want a deeper flavor, add a pinch of nutmeg or cayenne pepper for an extra layer of warmth.

Pairing Ideas and Variations

This Cheesy Root Vegetable Gratin pairs wonderfully with roasted meats like turkey, lamb, or chicken. For a complete meal, serve it alongside a fresh salad and crusty bread. You can also drizzle a bit of balsamic glaze over the top for a touch of acidity, which balances the richness of the cheese.

For a lighter version, swap out the heavy cream for coconut cream and use dairy-free cheese to make this dish vegan-friendly. To add some heat, consider mixing in some red pepper flakes or a dash of smoked paprika.
