That’s the magic of garlic butter sweet potato stacks, a dish that transforms the humble sweet potato into a decadent treat. This recipe not only packs a punch of flavor but also adds a touch of elegance to your dining table, making it perfect for both cozy family dinners and special occasions.


To create these decadent garlic butter sweet potato stacks that will add a touch of sophistication to any meal, gather the following ingredients, making sure to prep as detailed:

  • Sweet potatoes, 3 large, peeled and thinly sliced into rounds
  • Butter, 4 tablespoons, melted
  • Garlic, 3 cloves, minced
  • Fresh thyme, 2 tablespoons, chopped finely
  • Salt, 1 teaspoon
  • Black pepper, ½ teaspoon
  • Parmesan cheese, ½ cup, grated
  • Fresh parsley, for garnish (optional)

Start with quality sweet potatoes, ensuring they are firm and free of blemishes for the best results. The thin slicing is crucial for uniform cooking and an appealing stack presentation, so use a mandoline slicer if available for consistency in thickness. Assembling these ingredients will prepare you for the succulent flavor journey infused with garlic and enriched with buttery goodness.

Equipment Needed

To craft the perfect garlic butter sweet potato stacks, you’ll need some specific kitchen tools. These tools will help you achieve uniform slices and consistency in your cooking, ensuring that each stack is as delicious as the last. Here’s what you should gather before you start:

  • Mandoline Slicer: This is crucial for creating even, thin slices of sweet potato. A sharp mandoline slicer ensures that your potato slices are uniform, which is essential for even cooking and an appealing stack.
  • Baking Sheet: You’ll need at least one, but possibly more depending on how many stacks you plan to make. The baking sheet will serve as the platform where your sweet potato stacks will beautifully roast.
  • Muffin Tin: Opt for a standard 12-cup muffin tin. This will help shape your sweet potato slices into neat stacks and ensure they cook evenly.
  • Parchment Paper: To prevent sticking and ensure easy cleanup, line your baking sheet with parchment paper.
  • Brush: A small pastry brush is perfect for applying the garlic butter mixture evenly across each sweet potato slice.
  • Cheese Grater: If you’re using a block of Parmesan, you’ll need a fine cheese grater. This will allow you to sprinkle freshly grated Parmesan over the stacks for that added savory touch.
  • Knife: A sharp chef’s knife is necessary for any prep work, like mincing garlic or chopping thyme.
  • Measuring Spoons and Cups: These will help you accurately measure all your ingredients, ensuring the flavors are perfectly balanced.

Make sure each piece of equipment is clean and ready to use. Gathering these tools in advance will streamline your cooking process, making it a more enjoyable and efficient experience.


Before you begin crafting your garlic butter sweet potato stacks, ensure you have all your ingredients and tools at hand. This preparation phase is crucial for a seamless cooking experience.

Preparing the Sweet Potatoes

Start by preheating your oven to 375°F (190°C). Next, wash your sweet potatoes thoroughly under running water to remove any dirt or impurities. Using a mandoline slicer, carefully slice the potatoes into even rounds, about 1/16-inch thick. These thin, uniform slices are key for even cooking and perfect stack formation.

As you slice, soak the potato rounds in a bowl of cold water to prevent browning and to remove excess starch. This step will help ensure that your sweet potato stacks cook up with a beautifully crisp exterior and tender inside. Once all the sweet potatoes are sliced, drain them and pat dry with a clean kitchen towel or paper towels to remove any excess moisture.

Making the Garlic, Butter Mixture

Let’s prepare the garlic butter that will bring richness and flavor to your stacks. In a small saucepan, melt 1/2 cup of unsalted butter over medium heat. Once melted, add 3 cloves of finely minced garlic to the butter. Cook this mixture for 1-2 minutes, just until the garlic is fragrant but not browned.

Remove the saucepan from the heat and stir in 1 teaspoon of salt, 1/2 teaspoon of black pepper, and a pinch of fresh thyme or rosemary for an extra layer of flavor. Stirring these ingredients together with the warm butter will help infuse it with the herbs and spices, preparing it to perfectly coat your sweet potato slices.


Let’s dive into the cooking steps that will guide you in crafting these delectable garlic butter sweet potato stacks. Follow each step closely to ensure your dish turns out perfectly flavorful and visually appealing.

Layering the Sweet Potato Stacks

  1. Begin by preheating your oven to 375°F (190°C). This ensures the oven is ready for your potato stacks to bake evenly.
  2. Next, lightly grease your muffin tin with butter or non-stick spray. This prevents the sweet potato stacks from sticking and makes removal easier after baking.
  3. Retrieve the thinly sliced sweet potatoes and pat them dry with paper towels to remove excess moisture. This step is crucial as it helps the sweet potatoes crisp up in the oven.
  4. Arrange the sweet potato slices in stacks within each muffin tin compartment. Aim for an even layering, typically placing about 8-10 slices per stack, depending on the size of your slices.
  5. Drizzle the previously prepared garlic butter mixture over each stack. Ensure each slice gets a generous coating, as this will infuse them with flavor and aid in the caramelization process.
  6. Finally, sprinkle a pinch of salt and pepper on each stack for added seasoning. This step enhances the natural sweetness of the potatoes and complements the garlic butter.

Baking the Sweet Potato Stacks

  1. Place the muffin tin in the preheated oven and bake for about 25-30 minutes. The exact time may vary depending on the thickness of your sweet potato slices.
  2. Halfway through the baking process, you might want to rotate the muffin tin to promote even cooking and prevent the edges from burning.
  3. Continue baking until the tops of the sweet potato stacks are golden and crispy, and the potatoes are tender all the way through.
  4. Once done, remove the muffin tin from the oven and allow the stacks to cool for 5 minutes in the tin. This settling time helps the stacks hold their shape when removed.
  5. Carefully remove the stacks using a spoon or a small spatoid. Plate immediately and serve while warm to savor the creamy interior and crisp, buttery edges.
