How To Make Cheesy Scalloped Potatoes | Potato Au Gratin

Melt 1 stick of butter in a skillet.

Add flour to the melted butter and whisk until smooth, cooking out the raw flour taste for 2-3 minutes.

Gradually add milk to the mixture, whisking until the desired smooth consistency is reached.

Add onions to the sauce (optional) and mix well.

Incorporate shredded cheese into the sauce, adding more milk as needed to maintain smoothness.

Add onion powder, black pepper, garlic powder, and salt to taste, mixing thoroughly.

Add potatoes to the cheese sauce and ensure they are well coated.

If desired, transfer to the oven or continue cooking on the stovetop, checking occasionally to prevent burning.

Cook on low heat for about 25 minutes, checking doneness with a fork.

Once potatoes are tender, add remaining cheese on top and place under the broiler to brown the cheese, monitoring closely to prevent burning.

Plate the scalloped potatoes and serve.
