🥘 Instant Pot Au Gratin Potatoes Ingredients

These common ingredients can be found in any typical grocery store if you don't already have them on hand. I like to use Russet potatoes, but Yukon golds would be another great option!

• Potatoes - 2 pounds of russet potatoes. You can peel them or leave the skin on, it is completely up to you!
• Chicken Broth - 1 cup of chicken broth.
• Onion - ¼ cup of either yellow or white onion that has been diced.
• Garlic Powder - ½ teaspoon of garlic powder.
• Paprika - ½ teaspoon of paprika.
• Salt - ½ teaspoon of salt.
• Pepper - ¼ teaspoon of ground black pepper.
• Evaporated Milk - ½ cup of evaporated milk. Or, you can use heavy cream if preferred.
• Cheddar - 1 cup of freshly grated cheddar cheese.

🍴 Equipment Needed To Make Au Gratin Potatoes

There are a few different pieces of equipment you'll need for preparing this dish. First of all, you'll want to have a mandolin to slice your potatoes. Of course, you could slice them by hand but it is much more work!

Obviously, you will also need your Instant Pot to cook your potatoes. Finally, grab a baking dish so that you can broil the potatoes to make them wonderfully bubbly and brown on top!

🔪 How To Make Instant Pot Au Gratin Potatoes

Nothing is difficult when it comes to using your Instant Pot! The hardest part is just slicing the potatoes!

Once you're done, you'll have 6 delicious servings of au gratin potatoes!

1. Slice potatoes. If you want to peel your potatoes, do that first. Then, using a mandolin, slice your 2 pounds of russet potatoes into ¼-inch thick slices. Rinse the potatoes under cold water to remove any extra starch.
2. Add to the pressure cooker. Layer your potato slices into the bottom of your Instant pot and then add in the 1 cup of chicken broth, ¼ cup of diced onion, and seasonings (½ teaspoon each of garlic powder, paprika, and salt, and ¼ teaspoon of pepper). Gently fold to combine.
3. Cook. Lock the lid and set the valve to 'seal'. Set the Instant Pot to manually pressure cook for 1 minute. Remember that the pressure cooker will take about 10 minutes to come up to pressure before it starts the timer.
4. Quick Release. Once the cooking time has been completed, carefully turn the valve to 'vent' to perform a quick release. Be very careful as hot steam will shoot out of the vent! Allow the Instant Pot to release all pressure before unlocking and opening the lid.
5. Melt the cheese. Next, add in ½ cup of evaporated milk (or heavy cream), 1 cup of cheddar cheese, and ½ cup of Monterey jack cheese. Gently stir the potatoes until all of the cheese has completely melted.
6. Place in a baking dish. Transfer your potatoes to a baking dish and set your oven's broiler to the lowest setting (if available).
7. Broil. Broil the potatoes on the lower rack of your oven until the top has begun to brown and is bubbling. Don't take your eyes off of the potatoes as they can quickly burn when under the broiler!
8. Rest and serve. Remove the potatoes from the oven and allow them to rest for 10 minutes in order to thicken up before serving.

Serve your potatoes with some grilled lamb shanks or bag roasted chicken for a wonderful dinner! Your entire family will love it! Enjoy!

💭 Angela's Pro Tips & Recipe Notes

• You can make this recipe with either peeled or unpeeled potatoes. I left the peel on mine, but feel free to peel them if you like!
• Instead of 1 cup of cheddar and ½ cup of Monterey jack, you can use 1½ cups of cheddar, Colby, Colby jack, or even a combination with Gouda or Gruyere! 
• ½ cup of evaporated milk or heavy cream is equivalent to 4 ounces.
• There are 4 ounces of cheese per cup. 1½ cups of cheese are equivalent to ⅓ pound.
• While you are only setting the Instant Pot to cook for 1 minute, the actual time will vary as it could take about 10 minutes for it to come up to pressure. 

🥡 Storing & Reheating

This dish makes some tasty leftovers! Keep any leftovers in the refrigerator in an airtight container for up to 4 days.

Reheating Instant Pot Au Gratin Potatoes

Reheat your potatoes in the oven or in the microwave, depending on your preference.
