Why Make This In The Pressure Cooker.

Making these in the pressure cooker takes about half the time of the oven version and it frees up your oven space.

I share two variations of the cooking recipe. The first uses the exact same white sauce as the oven version I use all the time.

The second version is a ‘mix all the sauce ingredients together and add to the potatoes,’ aka no cooking the béchamel sauce first. So it cuts down even further on the prep and cooking time. Perfect for weeknight suppers, right?

Expert Recipe Tips 

How about a few tips for making these Instant Pot potatoes au gratin because we all love tips that make cooking much easier right?

• Skin on potatoes. This recipe called for peeled sliced potatoes. My preference is unpeeled potatoes because of the contrast of the lovely potato skin to the soft, creamy, tender potatoes. Try both ways and see what you prefer.
• Reduce cook time. To cut down the cheese sauce cooking time, simply microwave the milk for about 1-2 mins before cooking with it.
• Remove lumps. You should not get any lumps in your cheese sauce, but if you do, then simply finish cooking the milk part of the sauce, strain through a sieve, put back in the pot before adding in the spices, and the shredded cheeses.

• Slice potatoes to the same size. Cut your potato to a similar thickness, not too thinly sliced though, so that they cook at similar rates. Using a mandolin to cut the potato slices will help.
• Chicken broth – If not vegetarian you can replace some of the milk with chicken broth. Oh and feel free to add some garlic and onion powder too.
• Cool before serving – let cool for a little bit before serving so that the cheesy sauce thickens a bit more.

Recipe Variations

• Make this with ham. If you want to make homemade Scalloped Potatoes with Ham, simple add in about 100g (2/3 cup) of cubed ham along with the cheese mixture.
• Make this with bacon. Simply add in about 100g (2/3 cup) of fried bacon along with the cheese mixture.
• To make quick Scalloped Potatoes. I suggest that you make them in the Instant Pot. I have given a recipe in the recipe card below. You can also microwave the potato rounds before cooking and this will reduce the baking times to about 45 minutes.
• Add in some sweet potatoes. Feel free to substitute a little of the potato with some sweet potatoes.
• Add in pesto. A spoon full or two of pesto adds in a whole new flavor profile.

Prep Ahead and Storing

Prep-ahead – just assemble them with the cheese mixture in the dish, and then refrigerate them unbaked. You can keep them 2-3 days this way. You can also bake them, and plastic wrap and refrigerate the cooled dish for up to 3 days.

Freeze. All you need to do is take the potatoes out of the oven a little bit before they are done. This helps protect their texture so they don’t fall to mush. You can then bake from frozen or thaw them in the fridge before baking.

FAQs

Which Potato Is Best For Homemade Scalloped Potatoes?

Great question. Russet potatoes have more starch and so they make a thicker and creamier sauce.
