The Recipe

Prep Time: 20 minutes
Cook Time: 60 minutes
Servings: 6
Calories: Approximately 320 per serving

Ingredients:

• 2 medium sweet potatoes, peeled and thinly sliced
• 2 medium parsnips, peeled and thinly sliced
• 2 medium beets, peeled and thinly sliced
• 3 cloves garlic, minced
• 1 ½ cups heavy cream
• 1 cup shredded Gruyère cheese (or sharp cheddar)
• 1 tsp thyme (fresh or dried)
• 2 tbsp olive oil
• Salt and pepper to taste

Instructions:

1. Preheat and Prepare: Preheat your oven to 375°F and grease a 9×13-inch baking dish. This ensures the gratin will cook evenly and makes for easy cleanup.

2. Slice the Vegetables: Peel and slice the sweet potatoes, parsnips, and beets into 1/8-inch rounds. This ensures even cooking and a beautiful layered effect. Using a mandoline can speed up this process and ensure uniform slices, which helps the layers cook at the same rate.

3. Flavor the Cream: In a saucepan over medium heat, combine the heavy cream, minced garlic, thyme, salt, and pepper. Simmer for 3–5 minutes to infuse the cream with flavor. The gentle simmering allows the garlic and thyme to release their oils and aromas into the cream, creating a delicious base for the gratin.

4. Layer the Vegetables: In the prepared baking dish, layer the vegetables, alternating colors for a striking presentation. Pour the infused cream evenly over the layers. This layering not only looks appealing but ensures every bite has a mix of sweet, earthy, and creamy flavors.

5. Add the Cheese: Top the dish with shredded Gruyère cheese. If you prefer a sharper flavor, you can substitute with sharp cheddar. Gruyère’s creamy texture and nutty flavor are perfect for creating a luscious, golden crust on top of the gratin.

6. Bake: Cover the dish with foil and bake for 35 minutes. Then, uncover and bake for an additional 20–25 minutes until the top is bubbly and golden. Covering with foil initially traps steam, allowing the vegetables to cook through without drying out, while removing the foil lets the cheese become crisp and golden.

7. Rest and Serve: Let the gratin rest for 10 minutes before serving. This allows the layers to set and makes serving easier. Resting also ensures that the flavors meld together, enhancing the overall taste profile.

Kitchen Tools You’ll Need

• 9×13-inch baking dish: Perfect for even cooking and serving a crowd.
• Sharp knife or mandoline: For slicing vegetables thinly and uniformly. A mandoline is especially helpful for achieving consistent thickness quickly and safely.
• Saucepan: To heat the cream and infuse it with flavor. This step is crucial for a well-seasoned gratin.
• Foil: Helps to trap steam and cook the vegetables evenly. It also prevents the cheese from burning before the vegetables are fully cooked.

The Benefits of Each Ingredient

• Sweet Potatoes: These are rich in vitamin A and add a natural sweetness that balances the savory elements of the dish. They’re also high in fiber and antioxidants, contributing to overall health.
• Parsnips: With a subtle sweetness and earthy flavor, parsnips add depth to the gratin and are high in fiber. They have a slightly nutty flavor that enhances the dish’s complexity.
• Beets: Not only do they bring a vibrant color, but they are also loaded with antioxidants. Beets are known for supporting heart health and improving blood flow.
• Garlic and Thyme: These aromatic ingredients infuse the cream with a savory depth that complements the sweetness of the vegetables. Garlic offers immune-boosting properties, while thyme adds a fragrant herbal note.
• Gruyère Cheese: Its nutty, creamy flavor melts beautifully, creating a luscious topping. Gruyère adds richness without overpowering the subtle flavors of the root vegetables.
• Heavy Cream: Adds richness and helps bind the layers together. It creates a smooth, velvety texture that makes this gratin irresistibly creamy.

What to Serve With This Gratin

This root vegetable gratin pairs wonderfully with a variety of dishes:

• Roast Chicken: The savory flavors of roast chicken complement the sweetness of the vegetables perfectly. The crispy skin and tender meat of the chicken make a delightful contrast to the creamy gratin.
• Green Salad: A fresh salad with a light vinaigrette can balance the richness of the gratin. Consider a mix of arugula, spinach, and radicchio with a lemon vinaigrette for a refreshing burst of flavor.
• Steamed Green Beans: Their crisp texture and vibrant color make for a delightful contrast. For added flavor, toss them with a bit of butter and toasted almonds.

Storage & Leftover Tips

• Refrigeration: Store any leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven at 350°F until warmed through. This method preserves the gratin’s texture and flavor better than microwaving.
• Freezing: This gratin can be frozen before baking. Assemble the dish, cover tightly, and freeze for up to 1 month. When ready to enjoy, bake from frozen, adding an additional 15-20 minutes to the cooking time. Freezing before baking ensures the vegetables retain their texture and don’t become mushy.
• Reheating Tips: To maintain the gratin’s creamy texture, reheat in the oven rather than the microwave. Cover with foil to prevent the top from browning too much during reheating.
