Cheesy Scalloped Potatoes

Step 3: Make the Cheese Sauce

In a medium saucepan, melt the butter over medium heat.

Add the diced onion and cook for 3 to 4 minutes until softened. Stir in the minced garlic and cook for another 30 seconds.

Sprinkle the flour over the onion mixture and whisk continuously for about 1 minute. This forms a roux, which will thicken the sauce.

Gradually pour in the milk and cream while whisking constantly to avoid lumps. Continue cooking for 4 to 5 minutes until the mixture thickens slightly.

Add the salt, pepper, and paprika. Remove the pan from the heat and stir in the cheddar cheese and half of the Parmesan cheese. Mix until smooth and creamy.

Step 4: Layer the Potatoes

Arrange one-third of the potato slices in an even layer across the bottom of the prepared baking dish.

Pour a portion of the cheese sauce over the potatoes, spreading it evenly.

Repeat the layers two more times, finishing with a final layer of sauce on top.

Sprinkle the remaining Parmesan cheese evenly across the surface.

Step 5: Bake the Casserole

Cover the dish loosely with aluminum foil and place it in the preheated oven.

Bake for 45 minutes.

After 45 minutes, remove the foil and continue baking for an additional 25 to 30 minutes. The top should become golden brown and the potatoes should be fork-tender.

If a deeper golden crust is desired, broil for 2 to 3 minutes at the end of baking, watching carefully to prevent burning.

Step 6: Let It Rest

Remove the casserole from the oven and allow it to rest for 10 to 15 minutes before serving.

This resting period helps the sauce thicken and makes the casserole easier to slice and serve.

Serving Suggestions

Cheesy scalloped potatoes pair wonderfully with:

• Roast chicken
• Baked ham
• Beef roast
• Grilled steak
• Pork chops
• Holiday turkey dinners

They can also be served alongside a crisp green salad for a complete vegetarian meal.

Tips for Perfect Results

• Slice potatoes evenly for consistent cooking.
• Use freshly grated cheese for the smoothest sauce.
• Avoid pre-shredded cheese if possible, as anti-caking agents can affect texture.
• Allow the casserole to rest before serving to help it set properly.
• For extra flavor, add cooked bacon, caramelized onions, or fresh herbs between the layers.

Storage and Reheating

Store leftovers in an airtight container in the refrigerator for up to 4 days.

To reheat, cover with foil and warm in a 350°F (175°C) oven for about 20 minutes, or until heated through. Individual portions can also be reheated in the microwave.
