Creamy Scalloped Potatoes – Easy 50-Minute Side

Scalloped Potatoes are the ultimate comfort food: thin slices of potato baked in a velvety, garlicky cream sauce until tender and topped with a golden, bubbling crust. This version cuts through the richness with a touch of sharp cheddar and fresh thyme, delivering a balanced, crowd-pleasing side.

What sets this recipe apart is the method. Instead of a heavy flour-based roux, we use a light cream reduction that clings to each slice without turning gluey. The result is a dish that's creamy but not cloying, with distinct layers that hold their shape when served.

With just 15 minutes of prep and 35 minutes in the oven, you get a side that feels special enough for Sunday dinner yet simple enough for a weeknight. Let's break down the steps so you can nail it every time.

About the Ingredients

2 lbs (900g) Yukon Gold potatoes, peeled and sliced 1/8-inch thick

Yukon Golds hold their shape and have a buttery flavor. Substitute russets, but they're starchier and may break down more.

2 cups (480ml) heavy cream

Full-fat cream gives the best richness. For a lighter option, use half-and-half but reduce baking time by 5 minutes.

1 cup (240ml) whole milk

Whole milk adds body. 2% works but the sauce will be thinner.

2 cloves garlic, minced

Fresh garlic is key. Garlic powder (1/2 tsp) can substitute in a pinch.

1 1/2 cups (170g) sharp cheddar cheese, shredded

Sharp cheddar provides bold flavor. Gruyère or Swiss are excellent substitutes.

1/2 cup (50g) Parmesan cheese, grated

Adds salty, nutty notes. Pecorino Romano works too.

1 tsp salt

Adjust to taste. Kosher salt is fine.

1/2 tsp black pepper, freshly ground

Freshly ground gives better flavor than pre-ground.

1/4 tsp ground nutmeg

A pinch elevates the cream. Optional but recommended.

1 tbsp fresh thyme leaves

Adds freshness. Use 1 tsp dried thyme if needed.

Tips & Tricks

• Slice potatoes uniformly using a mandoline or sharp knife to ensure even cooking.
• Don't skip the nutmeg—it enhances the creaminess without tasting nutty.
• Let the dish rest 10 minutes after baking to allow the sauce to set; it will slice cleaner.

Step-by-Step Instructions

1. Preheat and Prep

Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or nonstick spray.

2. Simmer the Cream

In a medium saucepan, combine heavy cream, milk, garlic, salt, pepper, and nutmeg. Heat over medium until just simmering, then remove from heat. This infuses flavor and helps the sauce thicken.

3. Layer the Potatoes

Arrange half of the potato slices in the dish, slightly overlapping. Sprinkle with half of the cheddar and thyme. Repeat with remaining potatoes, cheddar, and thyme.

4. Pour the Sauce

Pour the warm cream mixture evenly over the potatoes. Press down gently with a spatula to ensure the sauce reaches all layers. Sprinkle Parmesan on top.

5. Bake Covered

Cover with foil and bake for 25 minutes. The foil traps steam, cooking the potatoes through without drying out.

6. Uncover and Brown

Remove foil and bake an additional 10-15 minutes, until the top is golden brown and the edges are bubbling. A knife should pierce the potatoes easily. For extra crispness, broil 2-3 minutes.

7. Rest and Serve

Let stand 10 minutes before serving. This allows the sauce to thicken and set, making it easier to portion.

Delicious Variations

• Add 1 cup cooked ham, diced, in layers for a heartier dish.
• Swap cheddar for Gruyère and add caramelized onions for a French twist.
• Use sweet potatoes for a vibrant, slightly sweet version—reduce baking time by 5 minutes.
