Layers of thinly sliced potatoes in a rich cream sauce with onions are baked to perfection in this delicious Scalloped Potatoes Recipe. These potatoes are the perfect comfort food side dish for your holiday (or ANY day) dinner!
I’ve always had a weakness for potatoes – I love them any way they are cooked and can eat them as my entire meal. This dish is no exception to that and it’s surprisingly easy to prepare!
What You’ll Need
- Butter – I use unsalted butter so I can better control the saltiness to my personal taste.
- Yellow onion
- Garlic – Feel free to increase or decrease the amount of garlic to your personal preference.
- Thyme – I use a tablespoon of fresh thyme leaves. If you’re using dried thyme use 1 teaspoon.
- Flour (all-purpose)
- Salt and black pepper
- Ground nutmeg – Nutmeg adds a very slight hint of sweetness to this dish. It’s not required but I love it!
- Half-and-half – A mixture of half whole milk and half heavy cream. If you can’t find half-and-half, you can use 1 cup of whole milk and 1 cup of heavy cream.
- Chicken stock – Chicken broth can be substituted for chicken stock.
- Potatoes – Thinly sliced Yukon gold potatoes (russet potatoes can also be used). Using a mandoline makes slicing so much easier.
- Parmesan – Traditional scalloped potatoes are in a rich cream sauce (without cheese), but I did top these potatoes with a little freshly grated Parmesan. I recently purchased this rotary cheese grater and it makes grating hard cheeses so easy.
