How to Make Sweet Potato Scalloped Potatoes with Walnuts and Toasted Marshmallows Recipe
Step 1: Prep Your Oven and Dish
Start by preheating your oven to 400°F, the perfect temp to create tender potatoes and a beautifully toasted top. Grease a 2-quart casserole dish with nonstick spray to ensure your scalloped potatoes don’t stick, making cleanup a breeze later on.
Step 2: Arrange the Sweet Potatoes
Take those thin sweet potato slices and tuck them upright into the dish, slice side down. Packing them tightly allows for even cooking and creates those perfectly tender layers that define this dish’s charming texture.
Step 3: Make the Spiced Butter Mixture
In a saucepan over medium heat, melt your butter until it’s luscious and golden. Stir in the brown sugar, water, cinnamon, nutmeg, cloves, and salt, cooking just until the mixture bubbles gently. This fragrant sauce will seep into the potatoes, infusing them with warm spice and sweetness.
Step 4: Bake Covered
Pour about three-quarters of the warm butter mixture evenly over your sweet potato arrangement. Cover the dish tightly with foil to trap moisture and allow the sweet potatoes to become melt-in-your-mouth tender as they bake for 45 minutes.
Step 5: Add the Final Touches and Broil
Once the baking is complete, carefully remove the foil and drizzle the remaining butter sauce over the top. Sprinkle on the chopped walnuts and mini marshmallows, then place the dish under the broiler for 1 to 2 minutes. Watch closely as the marshmallows toast to a golden, bubbly perfection. This step brings that signature Sweet Potato Scalloped Potatoes with Walnuts and Toasted Marshmallows Recipe flair.
Step 6: Rest Before Serving
Let your beautiful creation rest for about 5 minutes to set and cool slightly. This pause allows the flavors to settle and makes serving easier without losing a single drop of the delicious sauce.

Garnishes
For a bit of fresh contrast, sprinkle a few chopped fresh parsley leaves or a light dusting of extra cinnamon atop your marshmallow layer just before serving. This brings a pop of color and freshness that balances the richer elements of the dish perfectly.
Side Dishes
This sweet and spiced casserole pairs wonderfully with savory mains. Think roasted turkey, glazed ham, or herb-seasoned grilled chicken. A crisp green salad or sautéed green beans also help round out the meal, offering a crunchy, fresh complement to the creamy potatoes.
Creative Ways to Present

Make Ahead and Storage
Storing Leftovers
Once cooled, cover the leftover casserole tightly with plastic wrap or transfer it to an airtight container. It will keep well in the refrigerator for up to 4 days without losing its delicious flavor or texture.
Freezing
This dish freezes beautifully! Store it in a freezer-safe container for up to 2 months. Be sure to thaw overnight in the refrigerator before reheating to avoid a watery texture and to maintain the integrity of those toasted marshmallows.
Reheating
Reheat leftovers in a 350°F oven covered with foil for about 20 minutes, until warmed through. To revive the toasted marshmallows, broil the top for just a minute or two at the end—but keep a close eye to avoid burning.
FAQs
Can I use regular potatoes instead of sweet potatoes?
Absolutely! While this recipe shines with sweet potatoes for their natural sweetness and softness, regular potatoes can be used for a more traditional scalloped texture. You might want to adjust the spices accordingly to balance the flavors.
What if I don’t have mini marshmallows?
No worries! You can use regular marshmallows chopped into smaller pieces or even a marshmallow fluff spread over the top before broiling. The key is to get that caramelized, gooey topping that completes the dish.
Are walnuts necessary?
Walnuts provide a lovely crunch and a toasty flavor contrast. If you have allergies or don’t like nuts, pecans or even toasted breadcrumbs can add texture without overpowering the dish.
Can this recipe be made vegan?
To make a vegan version, swap butter for plant-based margarine and use maple syrup or coconut sugar instead of brown sugar if preferred. Use vegan marshmallows to keep that classic toasty finish without animal products.
How thin should the sweet potato slices be?
About â…› inch thick is perfect. Thin slices cook evenly in the given time and create those delicate, tender layers that are essential for the ideal Sweet Potato Scalloped Potatoes with Walnuts and Toasted Marshmallows Recipe experience.
