Step‑by‑Step Instructions for Cheesy Root Veggie Gratin

Step 1: Preheat & Prep
Begin by preheating your oven to 400°F (200°C). While the oven heats up, take a 3-quart baking dish and generously grease it with unsalted butter, ensuring an easy release for your delicious Cheesy Root Veggie Gratin after cooking.

Step 2: Slice the Veggies
Thinly slice the sweet potatoes, parsnips, and beets using a sharp knife or mandoline for uniformity. Aim for about 1/8-inch thick slices to ensure even cooking and promote that tender texture throughout the gratin. Set them aside as you prepare to combine flavors.

Step 3: Mix & Season
In separate bowls, combine the heavy cream with Parmesan cheese, and season each bowl of sliced vegetables with salt, pepper, and fresh thyme. Toss each vegetable gently to ensure they’re well-coated with the creamy mixture and evenly seasoned, enhancing the flavors of your Cheesy Root Veggie Gratin.

Step 4: Layer it Up
Pour a small amount of the creamy mixture into the bottom of your greased baking dish, spreading evenly. Sprinkle some minced garlic over the cream, then layer the sweet potato, parsnip, and beet slices in alternating rows, creating a beautiful pattern that showcases the colors and textures of your ingredients.

Step 5: Bake Covered
Once layered beautifully, sprinkle additional salt, pepper, and Parmesan cheese on top. Cover the dish tightly with aluminum foil and place it in the preheated oven. Bake for 30 minutes, allowing the vegetables to soften and absorb the creamy flavors, getting started on that irresistible Cheesy Root Veggie Gratin.

Step 6: Add Cheese & Finish Baking
After 30 minutes, carefully remove the foil to release steam. Generously sprinkle Gruyere cheese on top of the gratin, ensuring an even layer. Return the dish to the oven and bake uncovered for an additional 18-20 minutes, or until the cheese is bubbly and golden brown, creating that perfect melty texture.

Step 7: Garnish & Serve
Once done, pull the Cheesy Root Veggie Gratin from the oven and let it sit for a few minutes. Before serving warm, sprinkle fresh thyme over the top, adding a pop of color and herbaceous aroma that will be inviting for your family and ensure a delightful dining experience.

Cheesy Root Veggie Gratin Recipe FAQs

What type of sweet potatoes should I use?
Absolutely! For the best flavor and texture, opt for firm, medium-sized sweet potatoes with smooth skin. Look for those that are deeply colored, as they typically indicate a sweeter taste. Avoid any that have dark spots or softness, as these could affect the quality of your Cheesy Root Veggie Gratin.

What if my root vegetables are too thick or unevenly sliced?
Great question! If your slices are on the thicker side, they may require a bit more baking time to soften. I suggest using a mandoline slicer for uniformity next time. However, if you’re in a pinch, just keep an eye on them in the oven, testing for doneness with a fork.
