Easy Root Vegetable Gratin

Recipe Description

This Easy Root Vegetable Gratin makes a crowd-pleasing holiday side. It is not only easy to make, it’s delicious, too. A medley of thinly sliced root vegetables, such as parsnips, sweet potatoes, carrots, beets, and potatoes, baked in a cream sauce enriched with Parmesan cheese. Creamy, cheesy, and perfect! What’s not to love?

First, slice the root vegetables using a sharp knife or a mandoline. Using a mandoline is preferable as you’ll get even slices, and it’s much quicker. Generously butter a 3-quart baking dish and pour in some heavy cream. Layer the sliced vegetables in the baking dish and season with salt and black pepper. Top the veggies with grated Parmesan and pour over the remaining cream mixed with garlic. Cover the dish with foil and bake for 30 minutes. Then, uncover and continue baking until the vegetables are tender and the top is golden brown. Serve alongside your holiday dinner, and enjoy!
