To see a picture of this dish, you need only look at the one for “Scalloped Potatoes”. These two dishes look exactly the same.

Well, have I got an exciting, time saving way to make scalloped potatoes (excuse me – au gratin potatoes) with lots of cheese and caramelized onion. And yes, I have a very similar recipe for Scalloped Potatoes on this site, but it doesn’t contain caramelized onion. And I have found that I really like that little bit of caramelized onion in my potato casseroles.

Which brings me to an interesting point that I feel you too should know.

A traditional scalloped potato casserole does not contain cheese. Instead, the potato slices are cooked in a cream sauce made of whole milk, heavy cream, and often fresh herbs. However, you will still find many recipes calling themselves “scalloped potatoes” that contain cheese. Are you now as confused as I am? And does it really make a darn bit of difference what these potatoes are called? Of course not. But I always like to educate my readers on the finer points of haute cuisine. But back to the time saving aspect of this dish that I promised to reveal in the first sentence of this post. (I do so ramble on and on sometimes……) (Sometimes?)

Anyway, I pre-cook my potatoes when I make potato casseroles. Thus, saving about 1½ hours of oven time. Plus, the fear that the bloody potatoes will never get tender. Or at least not in our lifetime.

So, if you too love potato casseroles, you might enjoy having this recipe in your recipe arsenal. And just in case you are interested, using cornstarch in place of flour makes these babies gluten free. But if you prefer, you can always use flour.

Well, that’s it for today. It’s very windy today with rain in the forecast. But that’s OK. We need more snow in the mountains. So, bring it on.

I hope you too are warm and snug in your own home. And feel as blessed as I do to be able to make that statement.

Peace and love to all.

2 lb. Yukon Gold or yellow potatoes (yellow potatoes are cheaper and just as good)

2 T. unsalted butter

¾ c. finely chopped onion

2 T. cornstarch

2 c. whole milk

freshly ground black pepper

4 c. shredded sharp cheddar cheese (or cheese or cheeses of choice) 

paprika

Peel potatoes and cut them in half. (And yes, I peel my potatoes for this recipe, because boiled potato skins tend to become tough.) Then slice each half potato into ⅓-inch slices. (If the potatoes are large, cut them in thirds and proceed from there.)

Place in a pan, cover with cold water, and bring to a boil. Reduce heat, add a bit of kosher salt, and cook until just about tender. (You don’t want mushy potatoes, so watch carefully). Drain.

Meanwhile, melt the butter in a medium sized saucepan. Add onion and cook until just starting to brown (caramelize). Then add cornstarch and let burble in pan for about a minute. Gradually whisk in the milk and pepper, bring to a boil, reduce heat, and let simmer for 2 minutes. Remove from heat and slowly stir in the cheese. Taste and adjust seasoning. (The sauce will be quite thick.)

Carefully add the cheese sauce to the potatoes. Scoop mixture into a lightly buttered baking pan and sprinkle lightly with paprika.

Bake in a pre-heated 350-degree oven for 30-40 minutes or until the top starts to brown and the sauce is bubbling around the edges of the casserole dish.

Remove from oven, cover, and let sit for a few minutes before serving.

Note: Don’t be afraid to mix and match the cheeses for this recipe. This dish is a perfect way to use up those bits and pieces of cheese that aren’t aging gracefully! Also, this recipe doubles and triples beautifully.
