Prepping the ingredients for potato soup

First up, prep and gather your ingredients and Instant Pot for the baked potato soup. If y'all don't drink much milk at home, I absolutely adore these little shelf stable guys that you can buy at Costco or most major grocery stores. I actually fell in love with shelf stable dairy when I lived abroad in France and was pumped when the trend finally made it here to the states.

celery stalk, carrot, potatoes, thyme plant, cornstarch in a bowl, onion, heavy cream, bone broth and milk for instant pot baked potato soup

They come in perfectly portioned single cup containers, so if you get a hankering for a latte or decide to make pudding one night, you can just pull one from the pantry without risking a whole container going sour. And if you're very short on refrigerator space like we are, they're amazing. Oh, and the tetrapaks are recyclable, so they're quite sustainable.

milk, heavy cream, chicken bone broth, butter, cornstarch as mis en place for loaded baked potato soup liquids

Open after you've measured your single cup of milk, pour a couple tablespoons of it into a small bowl with your cornstarch and stir with a fork to combine. This slurry will be your thickening agent to make the soup a bit more chowder-y than brothy. Set both the milk and slurry aside for later.

Next, wash and prep your veggies. Peel and medium dice an onion, small dice a celery stalk, and small to medium dice a carrot (no need to peel it, unless you're feeling fancy).

Depending on the potato type you use, you may or may not need to peel your taters before cutting them into a large dice. Wax potatoes can keep their skins, while thick skinned russets should definitely be peeled.

Next up, mince your garlic and thyme. You can actually mince them together to save time rather than keeping them separate. Told you this was a quick recipe!

Making baked potato soup in the Instant Pot

One of the great things about the Instant Pot is the super convenient sauté function. Why did slow cookers never think of this?!? Anyway, it saves you the step of having a separate pan for browning anything, and it's just genius.

So, set your machine to sauté on high. Add a glug of olive oil (or 1-2 tablespoons of butter if you want to be extra indulgent) and wait for it to shimmer (or bubble). Add the mirepoix to the pot with some salt and pepper, then stir to coat.

TIP: Mirepoix is the French trinity of carrots, celery and onion.

Cook the mirepoix about 5-8 minutes, until the vegetables are beginning to soften. Add in the garlic and thyme and cook until fragrant, about a minute. Now add the remaining plain milk, bone broth or stock and the potatoes.

Seal the lid on the Instant Pot and switch it to the Manual/Pressure Cook setting. Pressure cook on High for 7 minutes, then do a quick release.

TIP: The quick release will release a lot of steam very quickly. Be sure to take the proper precautions to safeguard your skin and any cabinetry around. I like to keep a kitchen towel nearby to toss over the valve to keep it from steaming the underside of my cabinets.

Remove the lid and change the setting back to sauté. Add in the cream and the slurry, then allow to simmer for about 5 minutes until slightly thickened. Taste for seasoning, then plate it and enjoy! Sluuuuuurrrrrrrrppppp!

Frequently Asked Questions

What makes this Instant Pot baked potato soup "loaded"?

Why, all the fixins, of course! We love to top ours with some grated cheddar (preferably Trader Joe's Unexpected Cheddar), Cholula, sliced green onions and crumbled bacon. Feel free to dress it up however you like - cheese, sour cream, bacon, chives, green onions, chopped ham or turkey, hot sauce are all fair game.

Can I make this vegan or vegetarian?

Yes! To make this vegetarian, simply swap out the chicken bone broth for vegetable stock. These bacon bits are also totally vegetarian/vegan.

To make the soup vegan, you could ostensibly substitute an alternative milk and cream (e.g. coconut). I haven't tried it, though, so if you take a stab at it let me know how it goes in the comments!

What can I substitute for the corn starch?

Corn starch is an effective thickening agent, but if you're trying to avoid corn products, you can substitute:

6 tablespoon AP Flour - reduce initial pressure cook time to 6 minutes and increase simmer time to 10-15 minutes. This will not have as glossy of a finish, but should taste equally delicious.
1 tablespoon + 2 teaspoon Arrowroot Flour - same cook times
2 teaspoon either Instant Potato Flakes, Tapioca Starch or Rice Starch - same cook times

Be sure that whatever ingredient you decide to use, you still add to a slurry. The amount of milk required to absorb the thickening agent will vary, but the total amount of milk added to the soup should remain constant.

What kind of potatoes should I use?

I personally like to use a half and half mix of russet potatoes and gold potatoes for a bit of textural interest. Be sure to thoroughly wash either kind of potato before prepping. Russets will need to be peeled, while wax variety potatoes will just need to have eyes or any damage removed.
