Why You’ll Love Potato And Sweet Potato Bake Recipe
I love how this recipe combines two types of potatoes in one creamy, cheesy dish. The regular potatoes provide a hearty, savory base, while the sweet potatoes add a subtle sweetness that pairs beautifully with the sharp cheddar and Parmesan.
I also like the seasoned cream mixture. I warm heavy cream and whole milk with garlic, smoked paprika, thyme, salt, and black pepper before pouring it over the potato layers. As everything bakes together, the potatoes absorb those flavors while becoming tender.
Another reason I enjoy this recipe is that it looks impressive without requiring complicated preparation. Once I slice and layer the potatoes, most of the work happens in the oven. The golden Parmesan topping and optional fresh herbs make the finished casserole especially inviting when I bring it to the table.
Ingredients
(Note: All ingredient amounts are listed in the recipe card below.)
2 potatoes medium – peeled (russet or Yukon gold)
2 sweet potatoes medium – peeled
2 tablespoons butter
2 cloves garlic minced
1 ½ cups heavy cream
½ cup whole milk
1 teaspoon salt
½ teaspoon black pepper
½ teaspoon smoked paprika
½ teaspoon dried thyme
1 cup sharp cheddar cheese – shredded
¼ cup Parmesan cheese – grated
Optional: fresh thyme or parsley for topping
Directions
I preheat the oven to 375°F and grease a 9×13-inch baking dish.
I slice the sweet potatoes and potatoes into thin, even rounds about ⅛ inch thick, then set them aside.
I melt the butter in a saucepan over medium heat.
I add the minced garlic and cook it just until fragrant, which takes approximately 30 seconds.
I stir in the heavy cream, whole milk, salt, black pepper, smoked paprika, and dried thyme. I heat the mixture until warm without allowing it to boil, then remove it from the heat.
I arrange half of the potatoes and sweet potatoes in the prepared baking dish, alternating between the two varieties.
I pour half of the cream mixture evenly over the potato layer and sprinkle half of the shredded sharp cheddar cheese over the top.
I repeat the layers using the remaining potatoes and sweet potatoes, followed by the remaining cream mixture and cheddar cheese.
I finish the casserole by sprinkling the grated Parmesan cheese over the top.
I cover the baking dish tightly with foil and bake for 40 minutes.
I remove the foil and continue baking for an additional 20 minutes, or until the potatoes are tender and the top is lightly browned.
I let the potato bake rest for 10 minutes before serving. If desired, I garnish it with fresh thyme or parsley.
Servings and Timing
This recipe makes 6 servings. I allow about 20 minutes for preparation and 1 hour for baking, giving me a total time of approximately 1 hour and 20 minutes when I include the 10-minute resting period before serving.
I bake the dish covered for the first 40 minutes so the potatoes have time to become tender in the creamy sauce. I then uncover it for another 20 minutes, which allows the cheese on top to become lightly browned. I find that the final 10-minute rest also helps the creamy layers settle before I serve them.
Variations
I can use either russet or Yukon gold potatoes depending on what I have available. Russets give me a soft, hearty result, while Yukon gold potatoes bring a naturally buttery character to the dish.
When I want to change the cheese flavor, I can replace some of the sharp cheddar with another good melting cheese. Gruyère can add a nutty flavor, while mozzarella can make the layers especially melty.
For a little extra warmth, I can increase the smoked paprika or add a small pinch of cayenne pepper to the cream mixture. When I want more herbal flavor, I add fresh thyme along with the dried thyme.
I can also make the presentation more colorful by finishing the casserole with chopped fresh parsley or thyme just before serving. The fresh herbs provide a nice contrast to the rich cream and cheese.
Storage/Reheating
I let any leftovers cool before transferring them to an airtight container or covering the baking dish securely. I refrigerate the potato and sweet potato bake and use it within about 3 to 4 days.
For reheating individual portions, I can use the microwave until the potatoes are heated through. When I have several portions to reheat, I prefer placing them in an oven-safe dish, covering them with foil, and warming them in the oven. I can remove the foil near the end if I want the cheesy top to become slightly crisp again.
I can also prepare the components ahead of time, but I prefer baking the assembled dish close to serving so the potatoes have the best creamy texture and the cheese topping stays appealing.
FAQs
How thin should I slice the potatoes?
I slice both the regular potatoes and sweet potatoes into rounds approximately ⅛ inch thick. Keeping the slices thin and even helps them cook at approximately the same rate and become tender throughout the casserole.
Do I need to peel the potatoes and sweet potatoes?
Yes, for this recipe I peel both the potatoes and sweet potatoes before slicing them. This gives the finished bake a smooth, tender texture throughout the layers.
Can I use Yukon gold potatoes instead of russet potatoes?
Yes. I can use either russet or Yukon gold potatoes in this recipe. Both work well alongside the sweet potatoes, so I choose whichever variety I prefer or already have available.
Why do I cover the baking dish with foil first?
I cover the dish tightly with foil for the first 40 minutes to help the potatoes cook and soften in the creamy mixture. I then remove the foil so the top can brown during the final 20 minutes.
How do I know when the potato bake is done?
I check that the potato and sweet potato slices are tender and that the top is lightly browned. If a knife slides easily through the potato layers, I know the casserole is ready.
Can I make this potato and sweet potato bake ahead of time?
I can prepare some of the components ahead to save time, but I prefer baking the casserole closer to when I plan to serve it. This gives me the best combination of tender potatoes, creamy sauce, and freshly browned cheese.
Why shouldn’t I boil the cream mixture?
I only warm the cream mixture until it is heated through. I don’t need to boil it because it will continue cooking in the oven with the potatoes, and gentle heating is enough to combine the flavors before baking.
Can I use different cheese?
Yes. Although I use sharp cheddar and Parmesan in the original recipe, I can experiment with another cheese that melts well. I keep Parmesan on top when I want that savory flavor and lightly golden finish.
Why should I let the casserole rest before serving?
I let the casserole rest for 10 minutes after it comes out of the oven. This gives the hot cream and cheese mixture time to settle and makes the individual portions easier for me to serve.
What can I serve with potato and sweet potato bake?
I like serving this bake as a rich side dish alongside roasted chicken, turkey, beef, or other hearty main courses. I can also pair it with vegetables or a fresh salad to balance the creamy potatoes.

Notes
Russet or Yukon gold potatoes both work well; russets produce a soft, hearty texture while Yukon golds have a naturally buttery flavor.
Slice all potatoes about ⅛ inch thick and as evenly as possible so they cook at the same rate.
Gruyère or mozzarella can replace some of the sharp cheddar for a different cheese flavor.
For extra heat, increase the smoked paprika or add a small pinch of cayenne pepper.
Do not boil the cream mixture; it only needs to be warmed before being added to the casserole.
Check doneness by inserting a knife into the potato layers; it should slide through easily.
Store cooled leftovers covered or in an airtight container in the refrigerator for 3-4 days.
Reheat individual portions in the microwave or cover larger portions with foil and warm them in the oven.
