How to Make Cheesy Root Vegetable Gratin Recipe
Step 1: Prepare the Oven and Baking Dish
Start by preheating your oven to 375°F (190°C). Lightly grease a 9×9-inch baking dish or one of similar size. This ensures your gratin doesn’t stick and browns beautifully on the edges.
Step 2: Make the Creamy Garlic Sauce
In a small saucepan, melt the butter over medium heat. Add minced garlic and stir for just a minute until fragrant—this gentle cooking brings out garlic’s best flavor without bitterness. Next, stir in the heavy cream, salt, pepper, and thyme, bringing the mixture just up to a simmer. This sauce will soak into the vegetables, coating them with velvety richness.
Step 3: Layer the Vegetables
Arrange your thinly sliced root vegetables in the baking dish in overlapping rows. Alternate between Yukon gold potatoes, sweet potatoes, carrots, and parsnips. This layering not only looks stunning but ensures every bite delivers a balance of flavors and textures.
Step 4: Pour the Cream Sauce and Bake Covered
Pour the warm cream and garlic mixture evenly over the layered vegetables, letting it seep through every nook and cranny. Cover the dish with foil to trap moisture, then bake for 30 minutes. This allows the roots to soften gently and start melding with the creamy sauce.
Step 5: Add the Cheese and Finish Baking Uncovered
Remove the foil and generously sprinkle shredded Gruyère and Parmesan cheese on top. Return the dish to the oven uncovered and bake for another 20 to 25 minutes until the vegetables are tender and the top is honey-golden and bubbling with cheesy magic. Let the gratin cool slightly before serving—it’s worth the wait!
How to Serve Cheesy Root Vegetable Gratin Recipe
Garnishes
A sprinkle of chopped fresh parsley adds a bright, herbaceous pop of color and freshness that contrasts wonderfully with the rich, melted cheese and earthy vegetables.
Side Dishes
This gratin is a dream pairing with roasted meats like chicken or pork, as its creamy texture and rich flavors perfectly balance hearty protein. For a vegetarian meal, serve alongside a crisp green salad or sautéed greens for some freshness and crunch.
Creative Ways to Present
For a stunning presentation, bake the gratin in individual ramekins instead of a large dish. This way, you get elegant, personal portions perfect for dinner parties. You can also top it with toasted breadcrumbs for an extra crunchy texture or sprinkle with crushed nuts like walnuts or hazelnuts to add a surprising twist.
Make Ahead and Storage
Storing Leftovers
After enjoying your Cheesy Root Vegetable Gratin Recipe, store any leftovers in an airtight container in the refrigerator for up to 3 days. The flavors deepen as it chills, making it even tastier the next day.
Freezing
You can freeze the gratin before adding the cheese topping—wrap tightly and freeze for up to 2 months. When ready, thaw overnight in the fridge, then add cheese and bake as usual to freshen it up.
Reheating
Reheat leftovers gently in a 350°F (175°C) oven for about 15-20 minutes or until hot throughout. This prevents overheating, which can dry out the creamy layers. A quick microwave zap also works in a pinch, but be sure to cover the dish to retain moisture.
