Honestly, what could be better than fresh veggies with gooey cheese? It’s the perfect cozy dish: warm, hearty, and filled with rustic flavors, making it the ideal side dish for fall and winter meals.

Isabel’s Top Tip
You can use any vegetables that are in season. Don’t feel limited to just using parsnips, sweet potatoes, and beets! Other great choices are potatoes, cauliflower, carrots, squash, zucchini, eggplant, and onion. You can really get creative with whatever vegetables are in season. Just make sure to cut all of the vegetables to equal thickness. For more ideas, see my list of vegetables for gratin below.
Use a mandoline or other veggie slicer to make cutting the veggies easy. If you don’t have one, make sure to use the sharpest knife you have!
How to Make Veggie Au Gratin
- Preheat your oven to 400℉. Peel parsnips, sweet potatoes, and beets using a vegetable peeler or sharp knife, then cut them into slices with a knife or mandoline. Place each vegetable in a separate bowl.
- Add â…“ of your heavy cream and â…“ of your Parmesan cheese to each bowl, sprinkle with thyme, salt, and pepper to taste. Toss the vegetables to evenly coat them with the cream, cheese, and seasoning.
- Arrange the coated sliced vegetables in a cast iron skillet or baking dish in a way that pleases you, considering their colors. Pour the remaining heavy cream mixture from the parsnips and sweet potato bowls over the veggies. Do not use the mixture from the beets bowl, it will be too pink.
- Cover with aluminum foil and bake for 40 to 45 minutes. When the time is up, please remove it from the oven and sprinkle it with the remaining Parmesan cheese and Gruyère. Place it under the oven broiler for about 3 minutes to create a crispy, golden crust on top.
- Garnish with fresh thyme, and enjoy!
