Tips for Perfect Results

The perfect way to indulge in comfort food without the hassle.

As a chef, I have learned some valuable secret tips to create the perfect Instant Pot Potatoes Au Gratin. Follow these tips and you’ll never have to worry about your gratin potatoes turning out watery or dry again.

Firstly, it is important to slice your potatoes evenly. They should be not too thick or too thin, around ¼ inch thick, so they cook quickly and evenly. To do this conveniently and efficiently, use a mandolin slicer or a sharp knife.

When making Potatoes Au Gratin, it’s easy for the gratin potatoes to become watery. However, you can prevent this by sprinkling the potatoes with salt before layering them in your Instant Pot or baking dish. This will draw out excess moisture from the potatoes while cooking and keep them from becoming overly soggy.

To achieve creamy scalloped potatoes with a cheesy flavor and texture that complements the other ingredients, do not skimp on cheese. The recipe requires both Parmesan cheese and Mozzarella cheese in addition to heavy cream, evaporated milk as well as chicken broth for ultimate deliciousness.

Additionally, adding chopped fresh chives or parsley flakes at the end of cooking brings an enticing herb flavor to your Potatoes Au Gratin.

For those who don’t have access to chicken broth or prefer not to use it in their cooking, vegetable broths like mushroom or miso can be great substitutes for chicken broth.

Another trick is to cook at high pressure but for a short period of time (around 5 – 6 minutes) under manual pressure so that the slice potatoes and ingredients are perfectly cooked through.

Finally, be sure to let your Instant Pot Potatoes Au Gratin cool down slightly after cooking to allow the sauce thicken sufficiently that they have set properly before serving. Enjoy your delicious Easy Instant Pot Cheesy Scalloped Potatoes if you follow these tips!

What’s the difference between potatoes au gratin and scalloped potatoes?

The classic recipe for scalloped potatoes does not incorporate cheese. However, some modern versions may have added cheese. In contrast, au gratin potatoes require cheese to be distributed in layers between the potatoes and also on the surface of the dish.

What is the difference between au gratin and gratin?

The key factor in determining whether a dish is considered “au gratin” is whether cheese is used in the recipe. The term itself has French origins, with “gratin” referring to a crispy baked topping. This can be achieved in various ways, regardless of the use of cheese.

What is the recipe for gratin potatoes?

Let’s bring on the heat and preheat our oven to 350°! In a large saucepan, I like to melt some butter over low heat. As it begins to melt, I add some flour, salt and pepper to make a smooth paste. Gradually, I add milk to the mix and stir well to avoid lumps.

Once everything is well combined and I have a creamy and velvety sauce, I transfer it to a greased 2-qt. baking dish. I like my potatoes tender, so I cover the dish and let it bake in the oven for an hour. Then, I uncover it and put it back in the oven for an additional 30-40 minutes or until the potatoes are fork-tender. Trust me, this potato dish is going to be the highlight of your dinner!

Why are my au gratin potatoes watery?

Have you ever wondered why your au gratin potatoes turn out watery? One possible reason is that if you stored the sliced potatoes in water to avoid discoloring, but didn’t properly drain them and pat them dry before baking them, you may have introduced excess water into the dish.
