Easy Creamy Scalloped Potatoes Recipe

Indulge in Easy Creamy Scalloped Potatoes Recipe – a comforting classic with cheesy, creamy layers perfect for any gathering.

Ingredients

• 5 pounds Yukon gold potatoes, thinly sliced
• 2 tbsp unsalted butter
• 2 cloves garlic, minced
• 1 tbsp all-purpose flour
• 1 cup heavy cream (or whole milk/half & half)
• 0.5 cup Parmesan cheese, grated (plus extra for topping)
• 1 tsp fresh thyme
• 0.5 tsp kosher salt
• 0.5 tsp black pepper

Instructions

Step 1: Prep Work

Preheat the oven to 400°F (200°C) and generously grease a white oval ceramic baking dish so the scalloped layers will slide out cleanly after baking; this little extra care makes serving simple and keeps edges crisp. Wipe the polished quartz counter clean and gather your active tools — mandoline, large pot, whisk, and a slotted spoon — so everything is within reach for a calm, confident assembly.

Step 2: Slice the Potatoes

Use a mandoline to thinly and evenly slice five pounds of Yukon Gold potatoes into wafer‑thin rounds. The goal here is uniformity: thin translucent discs that will soften into silky layers when baked. Pile the slices into a single large bowl, and keep a small bowl for any offcuts or curls so the work area stays tidy. The mandoline stays nearby as the active tool, with a few paper‑thin potato shavings on the rim as evidence of the process.

Step 3: Make the Sauce

Melt unsalted butter in a roomy, heavy‑bottomed pot over medium heat and gently sweat minced garlic until fragrant — just a minute until the raw bite softens. Stir in the flour and cook briefly to form a light roux, stirring constantly so the butter and flour knit into a smooth paste. This is the foundation: warm, nutty aroma and a slightly grainy paste that will soon transform into a glossy, enveloping sauce.

Step 4: Thicken and Flavor the Sauce

Slowly whisk in the cream (or milk/half & half) so the roux loosens and the sauce becomes satin‑smooth. Cook for several minutes until it clings lightly to the whisk and just begins to thicken; fold in grated Parmesan, fresh thyme leaves, kosher salt, and cracked black pepper until the mixture is homogenous and silky, with flecks of herb and melted cheese. You should be left with a glossy, pale ivory sauce that coats the back of a spoon and smells richly of butter, garlic, and aged cheese.

Step 5: Combine and Cook

Gently fold the thin potato slices into the warm cheese cream so each disc is evenly coated; don't smash them — think delicate layering. Arrange the slices upright and slightly overlapping in the greased oval baking dish in neat rows so the edges toast and the centers stay tender, pouring any remaining sauce into the seams. Keep the white ceramic dish as the main vessel and leave a sauced spoon or small ladle resting beside it as the active tool.

Step 6: Bake

Sprinkle extra grated Parmesan over the arranged potatoes to encourage a golden, savory crust; tent the dish with foil and bake for 30 minutes, then uncover and continue baking for another 30 minutes until the top is deeply golden and bubbling, with caramelized edges peeking through the creamy seams.

Step 7: Cool and Serve

Let the scalloped potatoes rest for about 10 minutes so the sauce settles and slicing will be clean; finish with a scattering of finely chopped fresh thyme and a few whole sprigs for aroma. Serve warm and spoon‑friendly — the interior should be tender and layered, the top crisp and deeply caramelized, and the sauce luxuriously thick.

Notes

• Use a mandoline slicer for uniform potato slices.
• Add more cheese for an extra creamy texture.
• Ensure the sauce thickens appropriately before baking.
