Ingredients

• 3 large Yukon potatoes, thinly sliced (Russet Potatoes also work well)
• ½ medium onion, thinly sliced
• 2 cups whole milk
• 1 ½ cups shredded cheddar cheese (or a mix of Gruyère and Parmesan for extra flavor)
• 3 tablespoons unsalted butter
• 3 tablespoons flour (for thickening the sauce, optional)
• 3 cloves garlic, grated
• 2 teaspoons salt
• 1/2 teaspoon black pepper
• 1/2 teaspoon smoked paprika (optional, for added depth of flavor)
• 1/2 teaspoon dried thyme or fresh thyme leaves
• ½ cup shredded cheddar cheese, to sprinkle on top

How to Make Scalloped Potatoes Step-by-Step

Step 1: Prepare the Potatoes

1. Start by preheating your oven to 350°F (180°C).
2. Then peel and thinly slice the potatoes into 1/8-inch thick rounds using a sharp knife or mandoline slicer.
3. Also, lightly grease a 9×13-inch baking dish with butter or some cooking spray.

Step 2: Make the Creamy Sauce

4. Melt 3 tablespoons of unsalted butter in a medium saucepan or skillet. Once melted, whisk in 3 tablespoons of flour and cook for 1-2 minutes, stirring constantly until the mixture turns light golden and has a slightly nutty aroma.
5. Next, gradually whisk in the 2 cups of whole milk, ensuring a smooth consistency. Bring the mixture to a gentle simmer, making sure to stir frequently.
6. At this point, season with 2 teaspoons of salt, 1/2 teaspoon of black pepper, 1/2 teaspoon of smoked paprika (optional), and 1/2 teaspoon of dried thyme.
7. Lastly, reduce the heat to low and slowly stir in 2 cups of shredded cheese (a mix of cheddar, Gruyère, or Parmesan for extra flavor), allowing it to melt fully into a smooth, velvety sauce.

Step 3: Assemble the Dish

9. Layer half of the sliced potatoes evenly in a 9×13-inch baking dish.
10. Then top with half of the onions, then half of the creamy sauce
11. Repeat with the remaining potatoes and onions, then pour the rest of the sauce on top.
12. Sprinkle the remaining 1/2 cup of shredded cheese over the top.

Step 4: Bake

13. Bake at 350°F (180°C) for 1 hour or until the top is golden brown and bubbly.
14. Let the scalloped potatoes rest for 10 minutes before serving.

Easy Tips for the Best Scalloped Potatoes

• If you have a mandoline slicer, be sure to use it for even potato slices. This ensures that the potatoes cook more evenly.
• Don’t skip the resting time! Letting the finished dish sit for a few minutes after baking allows the sauce to set properly.
• Mix cheeses for a more flavorful dish— You can use sharp cheddar on its own, or you can add extra layers of flavors by using a mix of cheddar, Gruyère, and Parmesan.
• Make it Ahead: If you know you’ll be busy, you can prepare and assemble the scalloped potatoes up to a day in advance. Simply cover and refrigerate, then bake just before serving for the freshest taste and texture!

What to Serve with Scalloped Potatoes

Scalloped potatoes pair beautifully with:

• Roast beef or prime rib
