Classic Parmesan Scalloped Potatoes

Get ready to make the creamiest, most indulgent side dish that’ll have everyone asking for seconds (and thirds).

These aren’t your average scalloped potatoes – we’re talking layers of tender Yukon golds swimming in rich, garlicky cream and topped with golden Parmesan that bubbles to perfection.

The magic happens when that cream mixture gets all cozy with the potatoes, creating this amazing sauce that’s part comfort food, part fancy restaurant vibes.

Every forkful delivers creamy potato goodness with just the right amount of fresh parsley brightness and that irresistible cheesy top that’s crispy in all the right spots.

• Active Time: 20 mins
• Total Time: 1 hr 15 mins
• Yield: 8 to 10 serves

Ingredients

• 2 pounds Yukon gold potatoes, peeled and thinly sliced
• 3 cups whipping cream
• ¼ cup chopped fresh flat-leaf parsley
• 2 garlic cloves, chopped
• 1 ½ teaspoons salt
• ¼ teaspoon freshly ground pepper
• ½ cup grated Parmesan cheese

Steps

1. Preheat your oven to 400°F (200°C) and layer the sliced potatoes in a 13- x 9-inch or 3-quart baking dish. Overlap the slices slightly like shingles – this creates the perfect texture where some edges get crispy while the centers stay creamy. Make sure your potato slices are about ⅛-inch thick for even cooking; too thick and they won’t cook through, too thin and they’ll turn mushy.
2. Stir together the cream, chopped parsley, garlic, salt, and pepper in a large bowl until well combined. The cream mixture should smell fragrant from the garlic and look flecked with green parsley. Pour this cream mixture evenly over the layered potatoes, making sure it reaches all corners of the dish. You should see the cream pooling around the edges and seeping between the potato layers.
3. Bake at 400°F (200°C) for 30 minutes, stirring gently every 10 minutes to prevent the top from forming a skin and ensure even cooking. Use a large spoon to carefully push the top layer down into the cream – you’ll notice the cream starting to thicken and the potatoes becoming tender when pierced with a fork. After 30 minutes, sprinkle the grated Parmesan cheese evenly over the top.
4. Continue baking for 15 to 20 more minutes until the surface is bubbly and golden brown. The edges should be deeply golden and you’ll hear gentle bubbling sounds from the cream. The internal temperature should reach about 200°F (93°C) when tested with an instant-read thermometer in the center.
5. Let the dish stand on a wire rack for 10 minutes before serving. This resting time is crucial – it allows the cream to set up properly so your scalloped potatoes hold their shape when served instead of being soupy. The top should feel slightly firm to the touch but still give way when pressed gently.

Smart Swaps

• Gruyere cheese instead of Parmesan (1:1 ratio) – adds nutty, complex flavor
• Half-and-half instead of heavy cream – reduces calories while maintaining creaminess
• Fresh thyme instead of parsley – gives an earthy, sophisticated taste

Make It Diabetes-Friendly

Replace regular potatoes with cauliflower florets (same 2 pounds) to cut carbs from 35g to 8g per serving. Use 1 cup heavy cream + 2 cups unsweetened almond milk instead of 3 cups cream to reduce calories by 40% without sacrificing richness. Add 1 tablespoon cornstarch to the cream mixture to maintain the thick, luxurious texture. This modification drops the glycemic impact significantly while keeping all the comfort food satisfaction. Serve ½ cup portions paired with lean protein to further stabilize blood sugar.

Pro Tips

• Slice potatoes with a mandoline for perfectly uniform thickness – prevents some pieces from being undercooked while others turn mushy
• Let potatoes sit in cold water for 30 minutes after slicing to remove excess starch for cleaner layers
