Preparing Cheesy Root Vegetable Gratin
If you’re seeking a cozy, heartwarming dish to impress at your next gathering, look no further than this cheesy root vegetable gratin. It’s not only flavorful but also visually stunning. Let’s take a step-by-step journey through preparing this delightful dish.
Preheat and grease the baking dish
First things first, you want to set the oven's mood by preheating it to 400˚F. As your oven warms up, grab a 3-quart baking dish and generously grease it with some softened unsalted butter. This will help prevent sticking and add a bit of richness to the dish as it bakes. For an extra layer of flavor, a light dusting of garlic powder or Parmesan at the bottom can elevate your gratin even further.
Slice your root vegetables
Next up is the fun part: slicing those colorful root veggies! You’ll need to slice about 1-2 long sweet potatoes, 3-4 large parsnips, and 3-5 small beets. Aim for very thin rounds—using a mandoline slicer makes this process a breeze. The goal here is to ensure even cooking and beautiful presentation! Each vegetable will go into its own bowl to keep things organized. Have you ever tried mixing different colors and textures of vegetables for a stunning visual appeal? It’s science and art combined!
Mix vegetables with cream and seasonings
Now that your vegetables are prepped, it’s time to give them some love. Pour 4 tablespoons of heavy cream over the sweet potatoes and parsnips, and 2 tablespoons over the beets. Add ½ ounce each of grated Parmesan and 1 teaspoon of minced thyme to each bowl. Don’t forget to generously season with salt and pepper! Toss everything until well coated. The cream will help bind everything together, while the seasonings will bring out the natural flavors of your cheesy root vegetable gratin.
Layer the gratin in the baking dish
Next, it’s time to assemble. Pour the remaining ¼ cup of cream into the bottom of your greased baking dish. Sprinkle with another ½ ounce of grated Parmesan and minced garlic. Now take a stack of sweet potatoes and place them standing up at a bias in the baking dish; follow with parsnips and then beets. Repeat until you’ve created beautiful rows of color. Layering like this not only looks fantastic but also ensures every slice has a bit of each vegetable.
Bake and finish with cheese
Cover your cheesy root vegetable gratin with foil, and let it bake for about 30 minutes. This will soften the vegetables beautifully. Once that’s done, uncover the dish and sprinkle a generous amount of shredded gruyere on top. Bake for an additional 18 to 20 minutes until everything is fork-tender, the cheese is melted, and the top has a lovely golden-brown finish.
And there you have it—a rustic, mouthwatering dish that’s sure to impress. Garnish with fresh thyme and let the delicious aroma draw everyone to the table!

Variations on Cheesy Root Vegetable Gratin
Adding Different Root Vegetables
If you’re looking to make your cheesy root vegetable gratin even more exciting, consider incorporating a variety of root vegetables! Turnips, carrots, or rutabagas can add unique flavors and textures. For a little sweetness, try adding in some diced sweet potatoes alongside the regular potatoes. Just remember to adjust cooking times, as different vegetables will cook at varying rates.
Dairy-Free Alternatives
For those who are lactose intolerant or simply prefer a dairy-free option, it’s easy to swap out the heavy cream and cheese. Substituting cashew cream or full-fat coconut milk for the cream creates a rich base. Nutritional yeast can be sprinkled on top to give a cheesy flavor without the cheese itself! Check out this guide, for more on dairy-free ingredients.

Cooking tips and notes for Cheesy Root Vegetable Gratin
Best practices for slicing vegetables
When preparing your cheesy root vegetable gratin, uniformity is key—it ensures even cooking. Use a mandoline for slicing sweet potatoes, parsnips, and beets into thin, consistent rounds. If you don’t have one, a sharp knife will do the trick; just take your time to maintain an even thickness. This not only enhances the dish’s presentation but also helps each layer cook to perfection.
Tips to prevent discoloration
To keep your veggies looking vibrant, especially the beets, you can soak them in a bit of lemon water. It prevents oxidation and helps maintain their striking color. Just remember not to let them sit too long—immersion for 10 minutes is usually sufficient. Prepping your vegetables right before assembly is another great way to ensure they stay fresh-looking.
