Here is my favorite sweet potato recipe, with tender, seasoned potato slices layered with herbs, cheese, and a crispy breadcrumb topping that bakes up golden and bubbly.
These savory sweet potato stacks are perfect for weeknight dinners when you want something cozy but a little different. My kids actually ask for seconds, which is saying something when it comes to vegetables in our house!

What Kind of Sweet Potatoes Should I Use?
For this recipe, you’ll want to pick sweet potatoes that are similar in size so your stacks cook evenly. Look for ones that are firm to the touch without any soft spots or wrinkled skin – these will hold their shape better when sliced and stacked. Orange-fleshed sweet potatoes work perfectly here since they have that natural sweetness that pairs well with the savory herbs and seasonings. If you can only find really large sweet potatoes, no worries – just cut them in half lengthwise before slicing to make more manageable portions for your stacks.
Options for Substitutions
This simple recipe is pretty forgiving when it comes to swaps:
- Sweet potatoes: Regular russet potatoes work great here too, though they’ll have a different flavor profile. You could also try butternut squash or acorn squash – just adjust cooking time as they may cook faster.
- Butter: If you’re out of butter, you can use all olive oil instead (increase to about 1/2 cup total). For dairy-free, try melted coconut oil or vegan butter.
- Fresh rosemary: Dried rosemary works fine – just use about 1 teaspoon instead of the handful. Fresh thyme, sage, or even oregano make nice alternatives if rosemary isn’t your thing.
- Garlic powder: Fresh minced garlic (about 2 cloves) can replace the powder, but add it to the oil mixture so it doesn’t burn. Onion powder is another good substitute.
- Olive oil: Any neutral oil like vegetable or canola oil will work, though you’ll lose some of that rich olive oil flavor.
Watch Out for These Mistakes While Cooking
The biggest mistake when making sweet potato stacks is cutting the slices too thick, which leads to uneven cooking with burnt edges and raw centers – aim for uniform 1/4 inch slices using a mandoline or sharp knife for best results.
Another common error is not properly seasoning each layer, so make sure to brush every slice with the butter and olive oil mixture and sprinkle seasonings between each layer for maximum flavor.
To prevent your stacks from falling apart during cooking, gently press down on each stack before baking and avoid moving them around too much once they’re in the oven.
Keep an eye on the cooking time since sweet potatoes can go from perfectly tender to mushy quickly – they’re done when you can easily pierce through all layers with a fork but they still hold their shape.
What to Serve With Sweet Potato Stacks?
These savory sweet potato stacks make a perfect side dish for roasted chicken or grilled pork chops since the rosemary and garlic flavors complement meat so well. I love serving them alongside a simple green salad with lemon vinaigrette to balance out the richness of the buttery potatoes. They’re also great as part of a fall dinner spread with roasted Brussels sprouts and some crusty bread. For a lighter meal, you can even enjoy these stacks on their own with a dollop of Greek yogurt or sour cream on top.
Storage Instructions
Refrigerate: These sweet potato stacks keep really well in the fridge for up to 4 days in a covered container. They’re actually pretty tasty cold too, so you can grab them straight from the fridge for a quick snack. The rosemary flavor gets even better after sitting overnight!
Freeze: You can freeze these stacks for up to 3 months in a freezer-safe container with parchment paper between layers. I like to freeze them on a baking sheet first, then transfer to a bag so they don’t stick together.
Warm Up: To bring back that crispy texture, pop them in a 375°F oven for about 10-15 minutes until heated through. You can also use an air fryer at 350°F for 5-7 minutes if you want them extra crispy. Skip the microwave if you can – it makes them a bit mushy.

Ingredients
For the sweet potatoes:
- 2 sweet potatoes
For the seasoned butter mixture:
- 4 tbsp melted butter
- 1/4 cup olive oil
- 1 handful fresh rosemary, chopped
- 1 tsp salt
- 1/2 tsp black pepper
- 1/2 tsp garlic powder
Step 1: Prepare the Oven and Herb Mixture
- 4 tbsp melted butter
- 1/4 cup olive oil
- 1 handful fresh rosemary, chopped
- 1 tsp salt
- 1/2 tsp black pepper
- 1/2 tsp garlic powder
Preheat your oven to 400°F (200°C).
In a small bowl, combine the melted butter, olive oil, chopped rosemary, salt, black pepper, and garlic powder.
Stir well to create a flavorful mixture and set aside for later.
Step 2: Peel, Slice, and Season the Sweet Potatoes
- 2 sweet potatoes
- butter/olive oil/herb mixture from Step 1
Peel the sweet potatoes, then thinly slice them evenly.
Place the slices in a large bowl.
Pour the reserved butter and olive oil herb mixture over the sweet potatoes, tossing to ensure all slices are coated.
For extra flavor, you can swap the rosemary for thyme or another favorite herb.
Step 3: Stack the Sweet Potatoes and Prepare for Baking

Lightly spray a muffin pan with nonstick spray (or use a lined baking sheet if you prefer).
Stack the coated sweet potato slices in layers in each muffin cup, trimming the slices as needed to fit.
If the stacks are not stable, you can secure them with toothpicks on a baking sheet to prevent them from toppling over during baking.
I like to really pack the stacks tightly for the best presentation.
Step 4: Bake the Sweet Potato Stacks

Place the filled muffin pan (or baking sheet) in the preheated oven.
Bake for about 30 minutes, or until the sweet potatoes are tender.
Baking time may vary depending on the thickness of your slices and height of your stacks—check with a fork for doneness.
Step 5: Serve and Garnish
Remove the baked sweet potato stacks from the oven and let them cool slightly before serving.
For a finishing touch, sprinkle them with a little extra flaky salt.
I find that a final sprinkle of salt really brings out the sweetness of the potatoes.
