Ingredients
For the Gratin
- 1 tablespoon unsalted butter (softened)
- 12 long sweet potatoes (each about 2 inches thick, peeled)
- 3 to 4 large parsnips (trimmed and peeled)
- 3 to 5 small beets (peeled)
- 1 1/4 cup heavy cream (divided)
- 4 ounces grated Parmesan cheese (divided)
- 1 tablespoon fresh thyme (minced, divided)
- 1 clove garlic (minced)
- 1 ounce shredded Gruyere cheese
- Salt and freshly ground black pepper (to taste)
How to Make Cheesy Root Veggie Gratin
Step 1: Preheat the Oven
Start by preheating your oven to 400˚F. Grease a 3-quart baking dish with softened butter and set it aside.
Step 2: Prepare the Vegetables
Slice your sweet potatoes, parsnips, and beets into thin rounds. If you have a mandoline, now’s the time to use it—it’ll make the slicing super easy and even. Place each veggie in its own separate bowl.
Step 3: Coat the Vegetables
Pour 4 tablespoons of cream over the sweet potatoes and parsnips, and 2 tablespoons over the beets. Sprinkle each bowl with 1/2 ounce of grated Parmesan and 1 teaspoon of minced thyme. Don’t forget a generous pinch of salt and a few cracks of black pepper. Toss each bowl until the veggie slices are well coated.
Step 4: Layer the Ingredients
Pour the remaining 1/4 cup of cream into the bottom of your greased baking dish. Sprinkle in 1/2 ounce of Parmesan and add the minced garlic, spreading it out evenly.
Step 5: Assemble the Gratin
Time to layer! Start with a stack of sweet potatoes and arrange them standing up diagonally at the top of the dish. Next, add a row of parsnips, then a row of beets right after that. Keep alternating until you’ve filled the dish, creating about 6 rows of colorful, layered veggies.
Step 6: Bake Covered
Sprinkle the top with a little extra salt, pepper, and the rest of the Parmesan. Cover the dish with foil, then slide it into the oven. Let it bake covered for about 30 minutes or until the veggies have softened.
Step 7: Add Cheese Topping
Remove the foil, sprinkle shredded Gruyere over the top, and place the dish back in the oven. Bake uncovered for another 18-20 minutes. You’ll know it’s ready when the veggies are tender, the cheese is melted, and the top is nicely browned.
Step 8: Serve It Up!
Finish with a sprinkle of fresh thyme leaves. Serve it hot, and watch it disappear!

Common Mistakes to Avoid
Making a Cheesy Root Veggie Gratin can be simple, but there are a few pitfalls to watch for to ensure your dish turns out perfectly.
- Incorrect veggie slicing: Slicing the vegetables unevenly can lead to uneven cooking. Use a mandoline for uniform slices to help them cook evenly.
- Overcrowding the baking dish: If you pack too many veggies in, they won’t cook properly. Layer them loosely to allow for even heat distribution.
- Neglecting seasoning: Under-seasoning can result in bland flavors. Don’t forget to sprinkle salt and pepper on each layer of veggies for maximum taste.
- Skipping the resting period: Serving immediately after baking can make the gratin watery. Let it rest for a few minutes before serving to enhance flavors and texture.
- Using low-quality cheese: Cheap cheese may not melt well or provide the desired flavor profile. Opt for good quality Parmesan and Gruyere for the best results.
