Notes on Ingredients
- Potatoes: Russet potatoes work best for this soup, as their high starch content helps to thicken this soup and make it really creamy.
- Carrots: Feel free to omit the carrot for picky eaters, but they add a nice flavor and color to the potato soup.
- Broth: Use either low-sodium chicken stock or vegetable broth.
- White Distilled Vinegar: This is the SECRET ingredient to really good potato soup! The vinegar gives the soup tang and finishes it with almost a bright note. Use regular distilled vinegar for best results, as other vinegar varieties can overwhelm the flavor of the soup.
- Milk/Cream: Milk, half and half, or cream all work well. Obviously cream will make the richest and most luxurious potato soup, but low-fat milk can be used.
- Cornstarch: To thicken up the potato soup, I add cornstarch to the milk and add that combination to the soup after pressure cooking. This makes the soup thick and creamy, while still being gluten-free.
How to Make Instant Pot Baked Potato Soup
This is such an easy soup recipe to make. The most time-consuming part of making the soup is peeling and dicing the potatoes. Beyond that, it is almost completely hands-off.
- Wash and peel the potatoes.
- Cube the potatoes into 1-inch cubes. Be sure to cut the potatoes into evenly sized-cubes. This will ensure your potatoes cook evenly.
- Add the diced potatoes, shredded carrots, broth, vinegar, salt, pepper, garlic powder, and onion powder to the inner pot. Give everything a good stir to evenly combine all the ingredients.
- Place the lid on Instant Pot and be sure the vent knob is pushed towards sealed. Set the cooking time to 10 minutes on high pressure.
- Once cook time has elapsed, let the pressure release naturally for at least 15 minutes. If you tried to do a quick release of pressure before 15 minutes has elapsed, you will end up with a starchy mess spewing out of your pressure cooker.
- To thicken the potato soup and finish it with a creamy, rich finish, we want to turn our instant pot to saute after it has pressure cooked.
- While the soup is coming to a bubble, mix together the milk or cream with the cornstarch until the cornstarch is fully dissolved.
- Add that mixture to the bubbling soup and stir constantly, until thickened. It will take 3-5 minutes.
- Once thickened, hit cancel on the instant pot to turn off the saute function and ladel out the soup.
Just like baked potatoes, the toppings take this soup from good to spectacularly good.
Load up your potato soup just as you would a loaded baked potato.My favorite toppings include shredded cheddar cheese, diced cooked bacon, chives/green onions, and even a dollop of sour cream.
Instructions for Storage and Reheating
Allow any leftover Instant Pot Baked Potato Soup to cool slightly. Once cooled, store the soup in an airtight container in the refrigerator for 3-4 days. This is one soup I do not recommend freezing as the texture of the potatoes changes when thawed.
Reheat the soup in individual servings in the microwave or for multiple servings, heat in a saucepan over low heat on the stove. You may want to add a splash of stock or milk before reheating, as potato soup tends to thicken after refrigeration.
