Key ingredients & substitutions for the Classic Dish of Scalloped Potatoes

  • Potatoes | To make around six servings of scalloped potatoes, you’ll need about six russet potatoes, depending on their sizes. Yukon potatoes are another popular choice for this recipe.
  • Onion | Bring more flavor to the potatoes by cooking them with a yellow onion cut into thin slices. Substitute with a sweet or white onion if necessary.
  • Butter and olive oil | Use unsalted butter and olive oil to sauté the onions.
  • Chicken broth | Chicken broth adds flavor to the potatoes and is a fluid base for the cheesy sauce. If preferred, use vegetable broth in its place.
  • Heavy cream | Rich and creamy heavy cream creates a delicious sauce for your scalloped potatoes.
  • Dijon mustard | Add stone ground Dijon mustard for tangy notes to the creamy dish.
  • Salt and pepper | A dash of kosher salt and freshly ground black pepper are all you need to season this great recipe. However, some like to add a bit of garlic powder, too.
  • Gruyere cheese | You’ll sprinkle some of the grated gruyere cheese into the sauce and the rest on top of the final dish. Use sharp white cheddar cheese or a combination of your favorites if preferred.
  • Garnish | If desired, complete the scalloped potatoes with a sprinkle of freshly chopped herbs, like thyme, rosemary, and chives.

How to make the Best Scalloped Potatoes in the Pressure Cooker

Many home chefs are intimidated by scalloped potatoes and rarely make them except for special occasions. But with a bit of time and dedication, scalloped potatoes are absolutely possible to make!

STEP 1 | Slice the onion and potatoes

Start your delicious side dish of scalloped potatoes by prepping the potatoes and onions. So, scrub and rinse the russet potatoes, then peel the skin from each.

Next, cut thin slices as equal in size as possible, measuring around ¼ inch. Then, thinly slice the yellow onion.

STEP 2 | Cook the onions

Now, set out the instant pot and turn it on to the SAUTE function. Once the device indicates it is hot and ready, add the unsalted butter and olive oil, stirring until they are melted.

Then, toss in the onion slices to cook for 5 minutes or less until they are nice and soft.

STEP 3 | Deglaze the pot

Next, pour a cup of chicken broth into the instant pot and scrape the bottom with a wooden spoon to loosen any browned onion bits.

STEP 4 | Add the potatoes

Then, cancel the SAUTE function to get ready for the potatoes. Add the potato slices to the instant pot, gently stirring a few times to incorporate them into the chicken broth, onions, butter, and oil. Next, it’s time to lock the lid so the potatoes can cook.

STEP 5 | Cook the potatoes and prepare the baking dish

Once the lid is firmly closed, set the instant pot to cook on HIGH PRESSURE for just one minute. Keep in mind that it will take the appliance about 10 minutes to come to pressure, cooking at high pressure for only one minute.

In the meantime, lightly coat the bottom of a 2-quart oven-safe dish with nonstick cooking spray.

STEP 6 | Remove the ingredients from the instant pot

When the instant pot notifies you that the high-pressure cooking is complete, quick release the pressure.

Then, when the valve drops, transfer the soft potatoes and onion bits with a slotted spoon to the prepared baking dish. Get the oven ready by preheating it to broil.

STEP 7 | Begin the sauce

At this time, the instant pot should only contain some chicken broth mixed with any remaining oil and butter. Set it to SAUTE again to create the cheesy sauce.

After a minute or two, add in the heavy cream, Dijon mustard, salt, and pepper before the instant pot indicates HOT. Then, stir the sauce ingredients until smooth.

STEP 8 | Add cheese to the sauce

Next, add only 2 cups of Gruyere cheese and cook with the other ingredients until it is fully melted and silky smooth, frequently stirring. Then, pour the cheese sauce over the potatoes in the baking dish.

STEP 9 | Complete the recipe, broil, and serve!

Finally, top the cheesy potatoes with the remaining cheese, about half a cup. Place the dish under the broiler for around 6 minutes until the top is golden brown and bubbly.

All that’s left to do is remove the dish and serve your delicious from-scratch scalloped potatoes!

tips

  • For a restaurant-quality texture, slice the potatoes with a sharp knife at around ¼ to 1/3 of an inch. Do your best to make even slices.
  • Easily double or triple the recipe to serve 12 to 18 people. You can keep the same cooking time.
  • Add diced ham for some protein, if desired.
  • Before serving, it’s wise to let the potatoes cool a little, so they absorb all the flavors. Then, dig on in!

Frequently asked questions

Why are they called scalloped potatoes?

Another common misconception about scalloped potatoes for those unfamiliar with the recipe is an odd one when you really think about it — If you thought this dish received its name from the scallops it includes — think again. There are absolutely no shellfish of any kind in scalloped potatoes!

Some believe it gets its name by layering thin potato slices with a cheesy sauce, creating a scalloped pattern on the dish’s surface. Others credit the namesake to “collops,” an old English word describing the action of thinly slicing meat.

Can you slice potatoes ahead of time for scalloped potatoes?

To get ahead in the lengthy process of making scalloped potatoes, slice the potatoes for 12 to 24 hours before continuing with the recipe. Store them in an airtight container with water covering the potatoes in the fridge. You can also prepare the sauce beforehand, as long as you keep it in the refrigerator in a tightly sealed container.
