Ingredients for Idahoan Instant Potato Soup
Simple, comforting ingredients turn into a creamy bowl everyone will love.
| Ingredient | Amount | Notes |
|---|---|---|
| Idahoan Instant Potatoes 🥔 | 4 cups | Any variety works well |
| Chicken or Vegetable Broth 🍲 | 4 cups | Use vegetable for vegetarian |
| Whole Milk 🥛 | 2 cups | Full-fat for creaminess |
| Unsalted Butter 🧈 | 4 tbsp | Melted before adding |
| Yellow Onion 🧅 | 1 whole | Medium, finely diced |
| Garlic Cloves 🧄 | 3 cloves | Minced for depth |
| All-Purpose Flour 🌾 | 3 tbsp | For thickening soup |
| Shredded Cheddar Cheese 🧀 | 1 ½ cups | Sharp for best flavor |
| Sour Cream 🥣 | ½ cup | For topping and creaminess |
| Salt 🧂 | 1 tsp | Adjust to taste |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Fresh Chives 🌿 | 2 tbsp | Chopped for garnish |
| Cooked Bacon Bits 🥓 | ½ cup | Optional, omit for vegetarian |
The instant potatoes are the star—Idahoan brand is my go-to for that perfect texture. Grab the 4-cup flakes if you want it extra creamy. Any broth works, but Swanson Vegetable Broth is a solid vegetarian choice (and what I keep on hand). The whole milk is non-negotiable for that rich, velvety finish. Skip the low-fat here. For the cheese, block cheddar you grate yourself melts way better than pre-shredded.
No whole milk? Half-and-half at half the amount keeps it creamy. Out of fresh chives? Green onions work in a pinch. Want it thicker? Add an extra tablespoon of flour. The bacon bits are totally optional—omitting them keeps it vegetarian. If you’re using veggie broth, check the label for hidden fish ingredients (some brands sneak it in). The butter can be swapped for olive oil, but butter really does add that classic comfort flavor.
Leftovers keep 4-5 days in the fridge—honestly tastes better the next day. Freezes for 3 months (just leave out the sour cream and chives until reheating). I like to portion it into containers so lunches are sorted for the week (worth the extra minute).

Step-by-Step Instructions for Creamy Potato Soup
This comes together fast—just follow the steps and you’ll have a rich, velvety bowl ready to serve.
Step 1: Sauté the Aromatics for Depth
Melt the 4 tbsp Unsalted Butter in a large pot over medium heat. Add the finely diced 1 whole Yellow Onion and cook for 5-6 minutes until soft and translucent. Stir occasionally to prevent browning—you want sweet, mellow flavor, not char.
Add the 3 cloves Garlic Cloves and cook for 30 seconds until fragrant. Don’t let the garlic burn; it turns bitter fast. This base builds the savory foundation that makes the soup taste homemade, not instant.
Step 2: Create the Creamy Router
Sprinkle the 3 tbsp All-Purpose Flour over the onion and garlic mixture. Stir constantly for 1-2 minutes to cook out the raw flour taste—you’ll see it turn a light golden color. This step thickens the soup naturally without a grainy texture.
Slowly pour in the 4 cups Chicken or Vegetable Broth, whisking continuously to prevent lumps. Bring to a gentle simmer, then cook for 2-3 minutes until the mixture thickens slightly. The broth should coat the back of a spoon but still flow easily.
Step 3: Add Potatoes and Milk for Body
Stir in the 4 cups Idahoan Instant Potatoes—they’ll dissolve quickly, so keep mixing. Pour in the 2 cups Whole Milk and stir until fully combined. The mixture will look thin at first, but the potatoes absorb liquid as they hydrate.
Bring back to a gentle simmer, then reduce heat to low. Cook for 5-7 minutes, stirring often, until the soup thickens and the potatoes are fully rehydrated. You’ll notice it transform from milky to rich and creamy.
Step 4: Finish with Cheese and Seasonings
Remove the pot from heat and stir in the 1.5 cups Shredded Cheddar Cheese one handful at a time, letting each addition melt completely before adding more. This prevents clumping and ensures a smooth, velvety texture.
Season with the 1 tsp Salt and 0.5 tsp Black Pepper. Taste and adjust if needed—some broths are saltier than others. The cheese adds saltiness too, so go easy at first.
Step 5: Serve with Toppings
Ladle the soup into bowls and top each serving with a dollop of 0.5 cup Sour Cream, a sprinkle of 2 tbsp Fresh Chives, and a handful of 0.5 cup Cooked Bacon Bits. The toppings add a cool contrast to the hot soup and a satisfying crunch.
Serve immediately while hot and creamy. If the soup sits, give it a quick stir—the cheese can settle at the bottom. Leftovers keep well for 3 days in the fridge, though you may need to thin with a splash of milk when reheating.
Pro Tips For Making Idahoan Instant Potato Soup
- Sauté the Onion: Cook the diced yellow onion in butter until soft and translucent—about 5 minutes over medium heat. I learned this the hard way: skipping this step leaves the soup with a harsh, raw onion bite.
- Use Hot Broth: Heat your chicken or vegetable broth before mixing it with the instant potatoes. Cold broth makes the potatoes clump and turns the soup gluey instead of creamy.
- Whisk the Milk: Add the whole milk slowly while whisking constantly to prevent lumps. After burning a pot of lumpy soup once, I now use a wire whisk every time—no exceptions.
- Let It Rest: Give the soup 5 minutes off the heat before serving. Sounds weird, but it works: the potatoes absorb the liquid fully, and the flavor deepens.
Make-Ahead Tips for Leftovers
Prep Ahead Components
You can dice the 1 whole Yellow Onion and mince the 3 cloves Garlic Cloves up to 2 days ahead. Store them in separate airtight containers in the fridge. I like using small glass jars for this—they keep odors contained and you can see what’s inside. 💡
Cheese Prep
Grate the 1.5 cups Shredded Cheddar Cheese the night before and keep it refrigerated. Pre-shredded cheese has anti-caking agents that can make the soup grainy, so always grate fresh. This small step makes day-of cooking much faster.
Broth Measurement
Measure out the 4 cups Chicken or Vegetable Broth and 2 cups Whole Milk the night before and store them together in the fridge. Cold liquids will take slightly longer to come to temperature, so factor in an extra 5 minutes of cooking time.
Freezing Instructions
This soup freezes beautifully for up to 3 months. Let it cool completely, then portion into freezer-safe containers. Leave 1-inch headspace for expansion. I recommend using souper cubes for perfect single-serving portions.
Reheating from Frozen
Thaw overnight in the fridge, then reheat on the stovetop over medium-low heat for 10-15 minutes. Add a splash of milk if it’s too thick. Avoid microwaving from frozen as it can separate the dairy.
Toppings Prep
Cook the 0.5 cup Cooked Bacon Bits and chop the 2 tbsp Fresh Chives up to 3 days ahead. Store bacon in the fridge and chives in a damp paper towel in a sealed container. Add these fresh when serving for best texture. ❄️

Frequently Asked Questions
Can I use water instead of broth?
Yes, but the flavor will be milder. Use 4 cups water plus 1 tsp salt and ½ tsp garlic powder for better taste. Broth adds depth that water can’t.
How do I make it thicker?
Mix 1 tbsp cornstarch with 2 tbsp cold milk, then stir into simmering soup. Cook for 2-3 minutes until desired consistency. Avoid adding extra flour directly to prevent lumps.
Can I make this dairy-free?
Substitute 2 cups unsweetened almond milk for whole milk and use dairy-free cheese. Note that texture may be slightly less creamy. Always check labels for hidden dairy.
Why is my soup grainy?
This usually happens with pre-shredded cheese or undercooked flour. Always grate your own cheese and cook the flour for 1-2 minutes before adding liquids.
