Ingredients You’ll Need
You only need a handful of simple, wholesome ingredients to create this stunning dish, but each one plays an essential role—bringing depth, color, and texture that will impress everyone around the table.
- 2 large sweet potatoes (peeled and thinly sliced): The star of the show, providing natural sweetness and vibrant orange color.
- 3 tablespoons unsalted butter (melted): Adds richness and helps develop the golden, crispy edges.
- 2 tablespoons olive oil: Keeps the stacks moist with a subtle fruity note.
- 1/2 teaspoon salt: Enhances all the flavors perfectly without overpowering.
- 1/4 teaspoon black pepper: Gives a mild kick that balances the dish.
- 1 teaspoon fresh thyme leaves (plus extra for garnish): Brings an herbal brightness you’ll adore.
- 1/2 cup grated Parmesan cheese: Delivers that signature savory crunch and nutty flavor.
- Nonstick cooking spray or oil for muffin tin: Ensures every stack comes out clean and crisply cooked.
How to Make Crispy Parmesan Thyme Sweet Potato Stacks Recipe
Step 1: Preheat and Prep
Start by heating your oven to 400°F (200°C) and give a standard muffin tin a light coating of nonstick spray or oil. This simple step helps the stacks cook evenly and makes them a breeze to remove when done.
Step 2: Toss the Sweet Potatoes
In a large bowl, combine your thin slices of sweet potato with melted butter, olive oil, salt, pepper, fresh thyme leaves, and half of the grated Parmesan cheese. Gently toss everything so each slice is beautifully coated, promising a perfect crispy yet tender finish.
Step 3: Create the Stacks
Now for the fun part—building your stacks! Place about 6 to 8 slices of the coated sweet potatoes into each muffin cup, layering them neatly to maximize texture and flavor. Once all stacks are formed, sprinkle the remaining Parmesan generously over the tops for that golden crust.
Step 4: Bake Covered
Cover the muffin tin loosely with foil, then bake your stacks for 25 minutes. This covered phase steams the sweet potatoes just enough to become tender without losing their shape.
Step 5: Crisp and Brown
Remove the foil and bake for another 10 to 15 minutes. This is when the magic happens: the Parmesan crisps up, and the edges of the sweet potatoes turn gorgeously golden. The centers should be tender but not mushy, creating perfect bite-sized stacks you’ll fall in love with.
Step 6: Cool and Garnish
Give your stacks about five minutes to cool slightly before carefully removing them from the muffin tin. They’ll firm up just right and won’t lose their shape. Finish with a sprinkle of fresh thyme for a gorgeous, fragrant touch.
How to Serve Crispy Parmesan Thyme Sweet Potato Stacks Recipe

Garnishes
A little goes a long way when it comes to garnishes here. Fresh thyme sprigs make the dish pop visually and add a fresh herbal aroma that perfectly complements the Parmesan’s nutty richness. For an extra boost, try a light drizzle of honey or a pinch of crushed red pepper flakes for contrast.
Side Dishes
These sweet potato stacks shine alongside roasted meats like chicken or pork, bringing a lovely sweet-savory counterpoint. They also work beautifully paired with a crisp green salad dressed with lemon vinaigrette to balance out the richness. Vegetarian dinners will be equally elevated when served alongside sautéed greens or a mushroom ragout.
Creative Ways to Present
Feeling fancy? Serve these stacks in mini cast-iron skillets for a rustic yet elegant presentation. Alternatively, arrange them on a long serving platter with ribbons of fresh thyme and Parmesan shavings scattered artistically around. These details make the dish perfect for holiday gatherings or special occasions.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers (though they rarely last long!), store the sweet potato stacks in an airtight container in the refrigerator for up to 3 days. Keeping them chilled helps retain their texture without turning soggy.
Freezing
You can freeze these stacks by placing them in a single layer on a baking sheet until solid, then transferring them to a freezer-safe container or bag. Freeze for up to 2 months. When you’re ready to enjoy, thaw them overnight in the fridge before reheating.
Reheating
To reheat, pop the stacks into a preheated oven at 350°F (175°C) for about 10-15 minutes until warmed through and crisp again. Avoid microwaving to preserve that perfect crispy crust and tender inside.
FAQs
Can I use other herbs instead of thyme?
Absolutely! Rosemary or sage are wonderful substitutes that will give the stacks a different yet delightful herbal flavor. Feel free to experiment based on your preference or what’s fresh in your garden.
What’s the best way to slice the sweet potatoes?
For the best and most even texture, a mandoline slicer is your best friend. Thin, uniform slices ensure the stacks bake evenly, balancing crispiness and tenderness perfectly.
Can I make this recipe vegan?
Yes! Simply substitute the butter with a plant-based alternative and use nutritional yeast instead of Parmesan to keep that cheesy flavor without dairy.
Is it okay to skip the parmesan cheese?
While the Parmesan adds a delightful crunch and flavor, you can omit it if necessary. Just know that the crispy golden topping won’t develop the same richness, but the sweet potatoes and thyme will still shine beautifully.
How many stacks does this recipe make?
This recipe makes about 6 servings, with each serving consisting of 2 stacks. It’s perfect for a family dinner or a small gathering.
