These Cheesy Scalloped Potatoes are a classic holiday side dish that's very easy to make! Sliced potatoes are baked in a cheesy sauce until bubbly and delicious.
Whisk half and half with cornstarch in a glass measuring cup. It's easier to pour it into the pan, than using a bowl.
1 ¼ cup half and half, 1 ½ tablespoons cornstarch
In a medium saucepan or deep skillet, melt butter.
3 tablespoons unsalted butter
Slowly pour half and half mixture, ¼ cup at a time, whisking constantly. Wait for the sauce to thicken before adding more half and half.
Once all liquid is added and the sauce is nice and thick, season it with salt and pepper.
½ teaspoon salt, ¼ teaspoon black pepper
Add ¾ cup of shredded cheddar to the sauce and whisk until melted. Remove sauce from heat and set aside.
1 cup shredded cheddar cheese
Wash and peel potatoes.
4 large or 8 small Russet potatoes
Chop the onion finely.
½ of a small onion
Slice potatoes into ⅛" thick slices. This is the best thickness for this dish. Potatoes will cook perfectly without falling apart.
Arrange half of potato slices in the prepared dish. Sprinkle chopped onion on top. Top with remaining potatoes.
Whisk the sauce and pour over the potatoes. Stir gently so the sauce can coat potatoes.
Sprinkle remaining cheese on top and cover the dish with aluminum foil.
Bake for 1 hour OR until bubbly and the cheese is melted. Remove foil and broil for 2 to 3 minutes if you like the toasted cheese topping.
Remove dish from the oven and let cool slightly before serving.
Garnish with chopped parsley, dill, chives or green onions and enjoy!
Notes
My potatoes were on the smaller side, measuring about 3" in length. I used 8 of them.
Half and half can be found in the dairy section in most grocery stores. It's an equal blend of milk and cream.
To slice the potatoes, pull out the ruler and measure out. You cut a few and then you will be able to slice without measuring.
Feel free to jazz up this dish by adding bacon, green onions, ham, more varieties of cheese (like gruyere or gouda).
Any leftovers should be stored in the fridge since the sauce contains dairy. To reheat, pop it into the oven for 10 minutes or microwave for 40 seconds per serving.
