I would say that I’ve always loved scalloped potatoes growing up and although this isn’t our family recipe it’s a damn delicious one. And it’s a great comfort food like my Hearty Vegetable Hash or the Potato & Spinach Gratin.

Let’s take a look at the step-by-step of how to make them. Or you can just jump straight to the recipe below.

The basics

First things first, I don’t use cheese in my scalloped potatoes. I really don’t think they need it, as they are creamy enough on their own by making the roux sauce. So, let’s take a look.

Ingredients to make the Old Fashioned Scalloped Potatoes

Time to get cooking

Always start by preheating the oven to make sure it’s nice and hot when your dish is ready. Preheat to 350 degrees F.

Here’s where I made the first change, I cook the onions before adding them to the scalloped potatoes. It adds a touch of a caramelized falvour that’s delicious.

Slice the onions thin. Heat 1 tablespoon of olive oil in a medium skillet over medium heat. Add the onion cook for about 8 minutes. Until soft and slightly golden. Remove from heat.

get the potatoes ready

My personal opinion is that the potatoes need be thin, like really thin. This is how you get soft and creamy potatoes in the end dish. So, try to cut them as thin as you can like seen here. I would get I get 5 to 6 slices to an inch. If you find it tricky slicing with a knife, you could use a mandolin if you have one.

Rinse them in cold water and let them drain.

Make the Roux Sauce

Don’t know what a roux sauce is? A super simple basic sauce that’s used as a basis for so many delicious dishes. I probably make this sauce at least once a week. A staple.

In this roux sauce, I’m adding garlic. It’s not traditional but I find it gives a nice flavour to the sauce for this dish.

Melt the butter and add the garlic. Stir for a minute and add all the flour at once.

Whisk quickly to make sure you don’t end up with any lumps. Cook it over a medium heat, stirring constantly for about 2 minutes.

Gradually start adding the milk, whisking as you go. This is important to achieve a nice smooth thick sauce at the end. So add milk in about 1/2 cup increments and whisk until it starts to thicken then add another 1/2 cup. Do this until you have used all the milk and the sauce is thickened. The process takes about 8 minutes. Immediately remove the sauce from the heat.

time to put together our old fashioned scalloped potatoes

Get all our stuff in one place and your casserole dish. You can use a square, round, oval or rectangle dish. It’s all the same and it really doesn’t matter. About 8 inches in diameter is good, but it’s not essential. I used a rectangular dish this time around an it was about 6 x 9 inches. It worked perfect.

Oh, remember to stir the seasoning into the sauce like you see here. Now we’re all set to go.

Layer it up

I got three layers in this dish. You may get more if you dish is smaller and higher. Start with a layer of potatoes and then a few onions. Continue till you have reached the top.

pour over the sauce

Once you have finished the layers, pour over that sauce. Do it nice and gently so it doesn’t spill. Careful to make sure you have coated the entire dish.

Next, cover it with foil and bake in your preheated 350 degrees F oven for one hour. After an hour, remove the foil and bake for a further 20 – 30 minutes and is golden on the top.

fresh from the oven

I can’t tell you how great this dish is, so you’re going to have to make it and see for yourself. My whole family loves this dish and it goes great with so many things. I’m not going to lie, I can easily eat it on it’s own as a main course it’s that good.

So, if you’re looking for a delicious from scratch scalloped potato recipe, make this one.

It’s even great leftover. And I would say for best results, let it sit for about 10 minutes before serving.

What can i serve with my old fashioned scalloped potatoes

Lots of things is the answer! But here’s a few suggestions to set you on the right path. The only thing I would say is avoid serving the scalloped potatoes with any kind of creamy dish as the are creamy enough on their own. You’re looking for something little more fresher and simple. Let’s take a look a few of my suggestions.

I hope the recipe helps ward off the Monday blues. If not making it, just looking at it and reading about it. I know these are sure strange times for us all. On a uplifting note, we found out just a few days ago that we possibly be able to leave our homes for walks on the 2nd of May…whoohoo! As an avid walker, walking is probably what I missed the most during these past million weeks. Okay, reality this is week seven but it sure feels like an eternity. So a walking we will go.

And can I just say, how much we need it! Not only for our physical state of being but so save ourselves from going cookoo. I’m sure you’re all with me on that one.

So for now, I keep on keeping on. Cooking, baking, eating, some drinking (stating the obvious..ha), and even a little exercise to balance it all out.

I’ll see you all in a few days with a simple dessert that I think will be a big hit!

Happy cooking and stay sane.

  1. Could I prepare in advance up to the last 30 minutes (uncovered)? I try to make as many of my sides in advance as possible. I am thinking I would refrigerate the dish, and then pop it into the oven for the final bake.

    • Yes, you could make ahead and refridgerate up to the last stage. You may need to add a little extra time though as it will be going in the oven cold. Hope this helps.😊
