Creamy Cheddar Au Gratin Potatoes

Follow our step-by-step guide on how to make Creamy Cheddar Au Gratin Potatoes.

1. Step 1

   Begin by preheating your oven to a cozy 400°F (200°C) and generously butter a 1-quart casserole dish to ensure easy serving later.

2. Step 2

   Start layering half of the sliced potatoes at the bottom of the dish, sprinkling them with a pinch of salt and pepper for flavor.

3. Step 3

   Next, add a layer of onion rings, followed by the remaining potato slices, seasoning once more with salt and pepper to enhance the taste.

4. Step 4

   In a medium saucepan, melt butter over medium heat, then whisk in flour and 1/2 teaspoon of salt, cooking for about a minute until the raw flour aroma dissipates.

5. Step 5

   Gradually incorporate the milk, adding it in 1/4 cup increments while whisking vigorously to avoid lumps.

6. Step 6

   Keep stirring until the mixture thickens, which should take around 3 to 5 minutes.

7. Step 7

   Once thickened, introduce the shredded cheddar cheese all at once, stirring until it melts into a creamy sauce, which should take about 30 to 60 seconds.

8. Step 8

   Pour this luscious cheese sauce evenly over the layered potatoes in your casserole dish, then cover it snugly with aluminum foil.

9. Step 9

   Place the dish in your preheated oven and let it bake for approximately 1 ½ hours, or until the potatoes are tender and the sauce is bubbling with deliciousness.
