Ingredients You’ll Need
Each ingredient in this Cheesy Scalloped Sweet Potatoes Recipe plays a part in building that irresistible creamy, cheesy goodness. Some little tips here will help you pick the best and get the most from them.
- Sweet Potatoes: Choose firm, smooth-skinned sweet potatoes; their natural sweetness balances the savory cheese beautifully.
- Unsalted Butter: Using unsalted butter lets you control the saltiness perfectly, so be sure to season thoughtfully.
- Shallot: Adds a mild onion flavor without overpowering the dish; finely diced for even cooking.
- Garlic: Fresh minced garlic gives that subtle aromatic punch—don’t skip it!
- Heavy Whipping Cream: This is key for that luscious, silky sauce that hugs every potato slice.
- Parmesan Cheese: Sharp and nutty, Parmesan melts down smoothly and brightens the flavor.
- Gruyere Cheese: Brings a lovely creamy texture and slightly sweet, nutty note to the dish.

Variations
I love how versatile this Cheesy Scalloped Sweet Potatoes Recipe is — I often tweak it depending on what’s on hand or my mood. Feel free to make it your own!
- Make it spicy: I once added a pinch of cayenne pepper to the cream sauce and it gave the dish a lovely warm kick that my family raved about.
- Dairy-free variation: Swap heavy cream for coconut cream and use a dairy-free cheese to accommodate dietary needs without losing richness.
- Herb infusion: Sometimes I mix in fresh thyme or rosemary for a woodsy undertone that pairs beautifully with the sweet potatoes.
- Cheese swap: If you don’t have Gruyere, sharp cheddar works well too — just expect a slightly different flavor profile.
How to Make Cheesy Scalloped Sweet Potatoes Recipe
Step 1: Prepare the Sweet Potatoes with Care
Start by peeling and slicing your sweet potatoes very thinly — about ⅛-inch thick is perfect. I highly recommend using a mandoline if you have one, to get even slices that cook uniformly. If your slices are uneven, you’ll notice some parts getting mushy while others stay firm. Arrange these slices in a greased 9×13-inch dish, layering them slightly overlapping like shingles on a roof. Neat layering ensures even cooking and a beautiful finished look.
Step 2: Craft the Creamy Cheese Sauce
In a saucepan over medium heat, melt the butter, then add your finely diced shallots and minced garlic. Sauté for 2–3 minutes until fragrant and soft but not browned. From here, reduce the heat to low and carefully stir in the heavy cream, parmesan, Gruyere, salt, and pepper. Stir gently until the cheeses melt completely and your sauce is smooth and velvety. Trust me, this sauce makes all the difference — take your time for the best results.
Step 3: Bake and Enjoy
Pour the luscious cheese sauce evenly over your sweet potatoes, making sure every slice gets coated. Cover the dish tightly with foil to trap steam, then bake at 400°F for 30 minutes. This steam helps soften the potatoes gently. After that, remove the foil and bake uncovered for another 20 to 30 minutes until the top turns lightly golden and the potatoes are fork-tender. Let your scalloped sweet potatoes rest for about 5 minutes before serving — it helps everything set nicely.
Pro Tips for Making Cheesy Scalloped Sweet Potatoes Recipe
- Even Slices Matter: Using a mandoline ensures the sweet potatoes cook evenly and your layers look professional.
- Don’t Skip the Rest: Allowing the dish to rest after baking helps firm it up so it slices without falling apart.
- Cheese Choice: Try freshly grating your parmesan and Gruyere instead of pre-shredded for better melt and flavor.
- Avoid Watery Sauce: Take care when cooking the shallots and garlic—don’t brown them to prevent bitterness and wateriness in the sauce.
How to Serve Cheesy Scalloped Sweet Potatoes Recipe
Garnishes
I always top mine with freshly chopped chives before serving. The bright green color adds a lovely pop and the mild onion flavor cuts through the richness perfectly. Sometimes I’ll sprinkle a little extra grated parmesan on top for an extra cheesy finish.
Side Dishes
This recipe pairs brilliantly with roasted chicken or pork tenderloin for a comforting meal. I also love serving it alongside a simple green salad with a tangy vinaigrette to balance out all that creaminess.
Creative Ways to Present
For special occasions, I like baking this recipe in individual ramekins for a charming personal side dish. It feels fancy but is just as easy. Another fun idea is to bake in a decorative ceramic or cast-iron dish, letting the crust get extra golden and crispy around the edges — always a crowd favorite.
Make Ahead and Storage
Storing Leftovers
I store leftover scalloped sweet potatoes in an airtight container in the fridge. They keep well for up to 4 days and surprisingly, the texture still holds up wonderfully when reheated.
Freezing
Freezing works if you tightly wrap the dish or portion it out into freezer-safe containers. Just thaw in the fridge overnight before reheating. I’ve found that the sauce sometimes separates a bit after freezing, but gentle reheating and stirring brings it back.
Reheating
The best way I’ve found to reheat this recipe is covered in the oven at 350°F for 15–20 minutes. This keeps the topping from getting soggy and maintains that lovely cheesy crust. Microwaving works in a pinch but may make it a little watery.
FAQs
-
Can I use regular potatoes instead of sweet potatoes?
Absolutely! While the flavor will be different, regular Yukon Gold or Russet potatoes work great in this recipe. Just keep in mind the cooking time may vary slightly due to differences in moisture and density.
-
How can I make this dish dairy-free?
Try substituting the heavy cream with full-fat coconut milk or a creamy plant-based alternative. Use dairy-free cheese or nutritional yeast to maintain savory flavor. The texture might be a bit different but still delicious!
-
What’s the best way to slice the sweet potatoes?
Using a mandoline slicer is the easiest way to get uniform thin slices, which ensures even baking. If you don’t have one, a very sharp knife and steady hand will also do the trick—just take your time!
-
Can I prepare this recipe ahead of time?
Yes! You can assemble the dish completely, cover it tightly, and refrigerate for up to 24 hours before baking. Just add an extra 5–10 minutes to the baking time since the dish will be cold going into the oven.
Final Thoughts
This Cheesy Scalloped Sweet Potatoes Recipe is one of those dishes I’ve come back to time and time again because it feels like a warm hug on a plate.

Ingredients
Sweet Potatoes
- 3 medium sweet potatoes, peeled, thinly sliced into ⅛-inch rounds (about 4 cups)
Sauce
- ¼ cup (½ stick / 57 g) unsalted butter, room temperature
- 1 medium shallot, finely diced
- 2 teaspoons garlic, minced
- 1 ½ cups (357 g) heavy whipping cream
- 1 cup (100 g) parmesan cheese, shredded
- ½ cup (54 g) Gruyere cheese, shredded
- 1 teaspoon kosher salt
- ½ teaspoon black pepper
Garnish
- chives, chopped (for garnish)
Instructions
- Preheat oven: Preheat your oven to 400°F and lightly grease a 9×13-inch baking dish with cooking spray. Set the dish aside for now.
- Prepare sweet potatoes: Arrange the thinly sliced sweet potato rounds in the prepared dish, layering them so they slightly overlap to create an even base.
- Make sauce base: In a medium saucepan over medium heat, melt the butter. Add the finely diced shallot and minced garlic, cooking for 2 to 3 minutes until they are softened and fragrant.
- Add cream and cheese: Reduce the heat to low. Pour in the heavy cream, then add the shredded parmesan and Gruyere cheeses, along with the kosher salt and black pepper. Stir continuously until the cheese has fully melted and the sauce is smooth and creamy. Remove the pan from heat.
- Combine and bake: Pour the creamy cheese sauce evenly over the layered sweet potatoes in the baking dish. Cover the dish tightly with aluminum foil and bake in the oven for 30 minutes.
- Finish baking uncovered: After 30 minutes, remove the foil and continue baking, uncovered, for an additional 30 minutes or until the sweet potatoes are fork-tender and the top is lightly golden brown and bubbly.
- Rest and garnish: Remove the scalloped sweet potatoes from the oven and let them rest for 5 minutes to set. Before serving, sprinkle with freshly chopped chives for a bright, fresh finish.
Notes
- For easier slicing, use a mandoline to get even ⅛-inch rounds of sweet potatoes.
- If you prefer a thinner sauce, you can reduce the amount of cheese slightly or add a splash of milk to the cream mixture.
- Make sure to cover the dish tightly with foil during the initial baking to ensure the sweet potatoes cook evenly and stay moist.
- Feel free to substitute Gruyere with mozzarella or cheddar if needed, but Gruyere adds a nice nutty flavor.
- Leftovers can be stored in the refrigerator for up to 3 days and reheated gently in the oven.
