Minced Garlic – Fresh or pre-minced, this ingredient boosts the overall flavor profile of the dish.

Step‑by‑Step Instructions for Cheesy Root Vegetable Gratin

Step 1: Preheat the Oven
Start by preheating your oven to 375°F (190°C). This temperature will ensure your Cheesy Root Vegetable Gratin cooks evenly and achieves a nice, bubbly finish. While the oven is warming up, grab a baking dish and lightly spray it with nonstick cooking spray to prevent the gratin from sticking.

Step 2: Prepare the Vegetables
Next, peel and slice your choice of root vegetables—such as potatoes, carrots, and parsnips—into 1/8 inch rounds. Keep the slices uniform to ensure even cooking. Place the sliced vegetables in a large bowl for easy layering in your Cheesy Root Vegetable Gratin. The vibrant colors of the vegetables will inspire your kitchen’s warmth.

Step 3: Make the Cream Sauce
In a medium saucepan over medium heat, melt 2 tablespoons of butter. Once melted, add 2 minced garlic cloves and sauté until fragrant, about 1 minute. Then, slowly pour in 1 cup of heavy cream, season with salt and pepper, and let it simmer gently for 3-4 minutes. This creamy sauce will serve as the luscious base for your gratin.

Step 4: Layer the Ingredients
Now, it’s time to assemble your gratin! In the greased baking dish, create a base layer with half of the sliced root vegetables. Sprinkle a layer of your favorite cheese—like Gruyère or cheddar—over the vegetables. Pour half of the cream sauce evenly over this layer. Repeat with the remaining vegetables, cheese, and cream sauce, ensuring everything is well-distributed.

Step 5: Bake Covered
Cover the dish tightly with aluminum foil and place it in the preheated oven. Bake for 45 minutes, allowing the flavors to meld and the vegetables to soften. When you remove the foil, the Cheesy Root Vegetable Gratin should be starting to bubble at the edges, indicating it’s time for the final browning.

Step 6: Bake Uncovered
After 45 minutes, remove the foil and return the dish to the oven. Bake uncovered for an additional 15 minutes, until the top is golden brown and crispy. This is when your kitchen will fill with the irresistible aroma of cheese and roasted vegetables, making it hard to wait!

Step 7: Serve and Enjoy
Finally, remove the Cheesy Root Vegetable Gratin from the oven and allow it to cool slightly before serving. The golden crust will be a delightful contrast to the creamy, tender layers beneath. This dish makes a perfect side or a hearty main course, evoking warmth and comfort for everyone at the table.

How to Store and Freeze Cheesy Root Vegetable Gratin

Fridge: Store leftovers in an airtight container for up to 3 days. Make sure to cool the gratin to room temperature before sealing to maintain quality.

Freezer: Freeze the Cheesy Root Vegetable Gratin in a well-sealed container for up to 2 months. For best results, slice it into portions before freezing, allowing for easy reheating.

Reheating: To reheat, gently thaw in the fridge overnight and warm in a preheated oven at 350°F (175°C) until heated through. This ensures the creamy texture stays delightful.

Make-Ahead: Prepare the gratin ahead of time and store it in the fridge unbaked for 1 day. Simply bake when ready to serve for a fresh experience!
