Old Fashioned Scalloped Potatoes
These Old Fashioned Scalloped Potatoes are made with thinly sliced potatoes baked in a rich, creamy sauce. It’s a comforting side dish that pairs perfectly with a Sunday roast or a holiday meal.


Scalloped potatoes is one of those dishes that transforms simple ingredients into something special. Isn’t that what the best recipes do? I sure think so.
I found this classic recipe in several spiral-bound cookbooks from the 1950s and 1960s. It delivers tender, melt-in-your-mouth potatoes in a rich, creamy sauce. No fancy ingredients are needed; just a bunch of pantry and refrigerator staples.
My grandma used to make these every Easter because scalloped potatoes pair really nicely with ham. They’re also great with turkey, roast chicken, or a beef roast.

What you’ll need

- I used Yukon Gold potatoes, Russets or even red potatoes work well too.
- Any kind of dairy milk works here (skim, 2%, whole, etc.).
How to Make Old Fashioned Scalloped Potatoes
- Slice the potatoes as thinly as possible, about ⅛ inch or thinner. Place in a casserole dish.
- Cook the onion and butter in a skillet until the onion is soft.
- Add the flour and cook for one minute.
- Whisk in the milk, salt, and pepper. Cook until thick, 4–5 minutes.
- Pour the milk sauce over the potatoes.
- Cover and bake for one hour at 350°F. Uncover and bake for another 30 minutes. Serve.
Variations
- Want cheesy scalloped potatoes (au gratin potatoes)? Layer two cups of freshly shredded cheese into the casserole. One cup should go in the middle of the layers of potatoes, and the other cup should go on top. Cheddar and gruyere are the most common additions. One cup of parmesan would be tasty, too.
- Add herbs: two teaspoons of fresh herbs such as chopped thyme or chopped rosemary would be delicious! Whisk it into the milk sauce.
- Add ham: a cup or two of chopped ham is a great addition, like in this recipe for scalloped potatoes and ham. Use ham steaks from the store or leftover ham.
