Ingredients for Oven-Baked 5-Ingredient Hasselback Potato Casserole
This recipe uses five main ingredients, each contributing to its rich flavor and irresistible texture.
– 2 1/2 pounds russet potatoes, peeled: Russet potatoes are ideal because their high starch content helps create tender interiors while their edges develop a delicious golden finish. Choose potatoes that are similar in size for more uniform slices and even baking.
– 6 tablespoons butter, melted: Butter adds rich, savory flavor and helps the potato edges brown beautifully. It also combines with the garlic to create a fragrant coating that works its way between the slices.
– 2 teaspoons minced garlic: Garlic brings a warm, savory aroma that complements the mild potatoes and nutty Parmesan. Freshly minced garlic provides the most vibrant flavor, although jarred minced garlic works well for convenience.
– 1 cup grated Parmesan cheese, divided: Parmesan delivers a salty, nutty flavor and helps form a golden, savory crust. Most of the cheese is tossed with the potatoes, while the remaining portion is sprinkled over the casserole before the final stage of baking.
– 1 1/4 cups heavy cream: Heavy cream creates the rich, velvety sauce that surrounds the potatoes as they bake. It keeps the centers moist and tender while helping the flavors blend into a cohesive casserole.
You’ll also need: A little butter or nonstick cooking spray to grease a 9-by-13-inch glass baking dish. This is for preparing the pan and is not counted among the five main ingredients.
How to Make Hasselback Potato Casserole
Follow these simple steps to make a creamy, golden-brown potato casserole with perfectly tender slices and a delicious Parmesan topping.
Step 1: Prepare the Oven and Baking Dish
Preheat your oven to 400°F (200°C). Lightly butter or grease a 9-by-13-inch glass casserole dish to prevent sticking and make serving easier.
Prepare your baking dish before slicing the potatoes so everything is ready for assembly.
Step 2: Slice the Potatoes Thinly
Peel the russet potatoes and slice them into rounds approximately 1/8 inch thick. Try to keep the slices as even as possible so they cook at the same rate.
A mandoline slicer makes this step quick and consistent, but a sharp chef’s knife works just as well. If using a mandoline, use its hand guard to protect your fingers.
Step 3: Coat the Potatoes in the Creamy Garlic Mixture
Place the sliced potatoes in a large mixing bowl. Add the melted butter, minced garlic, 3/4 cup of the grated Parmesan cheese, and heavy cream.
Toss gently until the potato slices are evenly coated. Separate any slices that stick together so the buttery cream mixture can reach as many surfaces as possible.
This step gives the potatoes their rich flavor and helps create the creamy texture that makes this casserole so satisfying.
Step 4: Arrange the Potato Slices
Arrange the coated potato slices upright in tight rows inside the prepared baking dish. Overlap them slightly, keeping the rows close together without packing them so tightly that the cream cannot circulate.
Pour any remaining butter and cream mixture from the mixing bowl evenly over the potatoes.
The upright arrangement gives this dish its signature Hasselback-inspired appearance and exposes the edges to the oven’s heat.
Step 5: Bake Until Tender
Cover the casserole loosely with aluminum foil and bake for 40 minutes.
The foil helps the potatoes soften in the creamy mixture before the top becomes too brown. Keep the foil from pressing tightly against the potatoes.
Step 6: Add the Parmesan Topping
Carefully remove the foil and sprinkle the remaining 1/4 cup Parmesan cheese evenly over the casserole.
Return the dish to the oven, uncovered, and bake for another 25–35 minutes, or until the potatoes are fork-tender and the exposed edges are deeply golden.
The exact cooking time depends on the thickness of the slices and how tightly the potatoes are arranged. If the center is still firm, continue baking until the potatoes are tender.
For an extra-crispy top, place the casserole under the broiler for the final 1–2 minutes if needed. Watch it closely to prevent the Parmesan from burning.
Step 7: Rest and Serve
Remove the casserole from the oven and let it rest for 10–15 minutes before serving.
This resting time allows the creamy sauce to settle and makes the potato rows easier to serve. Spoon generous portions onto warm plates and enjoy the combination of tender potatoes, buttery garlic flavor, and golden Parmesan crust.
Pro Tips for the Best Hasselback Potato Casserole
1. Keep the potato slices uniform. Thin, even slices are the secret to getting tender potatoes throughout the dish. Thicker pieces may need additional baking time.
2. Choose russet potatoes. Their starchy texture works particularly well in creamy baked potato recipes. Yukon Gold potatoes can also be used, although the finished texture will be slightly different.
3. Use finely grated Parmesan. Finely grated cheese distributes more evenly throughout the cream mixture and creates a more consistent topping.
4. Do not skip the foil. Covering the casserole for the first part of baking helps the potato centers soften before the exposed edges become too dark.
5. Give the casserole enough time to rest. Allowing it to stand for at least 10 minutes helps the sauce settle and improves serving consistency.
6. Adjust the browning carefully. If the top needs more color, broil briefly and keep a close eye on the dish. Parmesan browns quickly under direct heat.
7. Make-ahead preparation: You can assemble the casserole a few hours ahead, cover it, and refrigerate it. For best quality, bake it soon after preparation because sliced potatoes can discolor. If using a glass dish, follow the manufacturer’s temperature guidance and avoid sudden temperature changes; transfer the mixture to an oven-safe dish before baking if necessary.
8. Store leftovers properly. Refrigerate leftovers in a covered container within two hours of serving and enjoy within 3–4 days. Reheat portions in the oven until heated through. A little extra cream can help restore moisture if the potatoes seem dry.
Delicious Variations to Try
Although the original five-ingredient version is wonderfully satisfying, you can customize it to suit your family’s preferences.
– Extra-cheesy potato casserole: Add a little shredded Gruyère or sharp cheddar for a richer cheese flavor. This changes the original five-ingredient recipe but makes a delicious variation.
– Herb and garlic potatoes: Sprinkle chopped fresh thyme or rosemary over the potatoes before baking for a fragrant, savory twist.
– Smoky Parmesan casserole: Add a small pinch of smoked paprika to the butter mixture for subtle smoky flavor.
– Loaded Hasselback potatoes: Scatter cooked, crumbled bacon and sliced green onions over the finished casserole just before serving.
– Lighter version: Replace some of the heavy cream with whole milk, understanding that the sauce will be less rich and may not thicken in quite the same way.
For the classic vintage-inspired version, keep the ingredient list simple and let the butter, garlic, cream, and Parmesan do the work.
What to Serve with Hasselback Potato Casserole
This creamy baked potato casserole is a versatile side dish that pairs beautifully with a wide variety of main courses.
– Roasted chicken: The savory chicken juices complement the buttery potatoes perfectly.
– Baked ham: A salty, smoky ham balances the richness of the cream and Parmesan.
– Meatloaf: Serve this comforting potato dish with classic meatloaf and a simple vegetable for an old-fashioned family dinner.
– Pork chops: Pan-seared or oven-baked pork chops make a hearty pairing.
– Holiday turkey: Add the casserole to your Thanksgiving or Christmas table for a delicious alternative to traditional mashed potatoes.
– Roasted vegetables: Green beans, broccoli, asparagus, or glazed carrots provide color and balance.
– Fresh green salad: Crisp lettuce, cucumbers, tomatoes, and a light vinaigrette cut through the richness of the potatoes.
– Warm dinner rolls: Soft rolls are perfect for soaking up the extra creamy sauce.
For a complete Sunday supper, serve the casserole with roasted chicken, green beans, a crisp garden salad, and warm rolls. It is a simple combination that feels special without requiring an elaborate menu.
Frequently Asked Questions
Can I make Hasselback potato casserole ahead of time?
Yes. You can assemble it a few hours before baking and refrigerate it. Keep it covered and bake it when you are ready. Allow extra cooking time if the casserole is still cold, and use an oven-safe dish that can safely handle the temperature change.
Why are my potatoes still firm in the middle?
The slices may be too thick, or the rows may be packed too tightly. Continue baking until a fork slides easily into the thickest pieces. Cover loosely with foil again if the top is browning too quickly.
Can I use a different type of potato?
Yes. Yukon Gold potatoes are a good alternative and produce a creamy texture. Russet potatoes remain an excellent choice for their starch content and ability to become tender beneath a browned exterior.
How do I make the top extra crispy?
Remove the foil for the final baking stage and allow enough time for the exposed edges to brown. A brief 1–2-minute broil can add extra color, but watch carefully to avoid burning the cheese.
Can I freeze this casserole?
Freezing is possible, but cream-based potato casseroles can change texture after thawing. The potatoes may become grainy or watery, and the sauce may separate. For the best creamy texture, refrigeration and reheating are preferable.
Is this the same as traditional Hasselback potatoes?
Not exactly. Traditional Hasselback potatoes are usually whole potatoes cut into thin, attached slices. This casserole uses separate thin potato rounds arranged upright to create a similar layered appearance in a family-sized baking dish.
