How to Make Scalloped Potatoes (Dauphinoise Potatoes) In the Oven

Step 1. Cook the butter and corn flour for a min until they form a paste.

Step 3. Quickly add in spices, seasoning and most of the cheeses, mix and switch off the heat.

Step 4. Layer half the potatoes slices in an oven dish and pour on half the cheese sauce.

Step 5. Add the remaining potato slices and top with the remaining cheese sauce and sprinkle on the rest of the cheese.

Step 7. Remove foil and bake uncovered for another 25 mins until cooked through and golden.

Instant Pot Scalloped Potatoes

You can make Instant Pot Scalloped Potatoes instead of the oven baked version. The plus point in this is that it takes about half the time of the oven version and it frees up your oven space.

I give two slight variations of the cooking recipe here. The first version uses the exact same white sauce as the oven version. This is the 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?

How To Make Instant Pot Scalloped Potatoes

Step 1. If making the quicker version, mix together the melted butter, cornflour, milk, double cream, spices, seasoning and most of the cheeses and set aside.

Then continue to step 4… OR:

Step 1. Cook the butter and corn flour for a min until they form a paste.

Step 2. Add the warm milk and whisk until smooth and then keep cooking for a further 2-3 mins until thick.

Step 3. Quickly add in spices, seasoning and most of the cheeses, mix and switch off the heat.

Step 4. Layer half the potatoes slices in your Instant Pot-ready dish and pour on half the cheese sauce.

Step 5. Add the remaining potato slices and top with the remaining cheese sauce and sprinkle on the rest of the cheese.

Step 6. Cover the potatoes with foil and place on a trivet.

Step 7. Add the water to the Instant pot insert, place the dish on the trivet in the Instant Pot, close pot, set valve to sealing, manual, high pressure and timer to 25 mins. You will need up to 35 mins if you use thicker slices.)

Step 7. Let cook till done and then do a quick pressure release.

Step 8. Remove the potatoes in the dish from the Instant Pot, discard the foil and place the potatoes under the grill / broiler for 3-5 mins until the top is golden and crispy.

Tips for Making Easy Scalloped Potatoes

How about a few tips for making Scalloped Potatoes, because we all love tips that make cooking much easier right?

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 it both ways and see what you prefer.

To cut down the cheese sauce cooking time, make sure to use warm milk. Simply microwave the milk for about 1-2 mins before cooking with it.

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 cheeses.

If you can, try and cut your potato to similar thickness so that they cook at similar rates. Using a mandolin to cut the potato slices will help.

Which Potato Is Best For Homemade Scalloped Potatoes?

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

Can Scalloped Potatoes Be made Ahead of Time?

The answer is yes, just assemble them with the cheese sauce in the dish, and then refrigerate them unbaked. You can keep them 2-3 days this way.

Can Scalloped Potatoes Be made In The Crockpot?

Yes, just layer them in the crockpot and cook for 4-5 hours on high and 8-10 hours on low.

Can Scalloped Potatoes Be Frozen?

Yes, this is one dish that can be frozen. 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.

Scalloped Potatoes 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 sauce.

Scalloped Potatoes With Bacon

If you want to make Scalloped Potatoes with bacon, simple add in about 100g (2/3 cup) of fried bacon along with the cheese sauce.

Quick Scalloped Potatoes

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 slices before cooking and this will reduce the baking times to about 45 mins.
