Can I Use Russet Potatoes for Potato Soup? The Definitive Guide
Yes, you can use russet potatoes for potato soup. However, be aware that they will yield a creamier, less textured soup compared to other varieties. Choosing the right technique will ensure the best possible results.
Russet Potatoes: A Soup-er Choice?
Russet potatoes, known for their starchy nature and floury texture when cooked, are a common pantry staple. While often favored for baking and frying, their suitability for potato soup is a frequent point of debate. The high starch content, while offering a desirable thickening effect, can also lead to a less chunky and potentially gluey soup if not handled correctly. Understanding these nuances is key to crafting a delicious potato soup with russets.
The Benefits and Drawbacks of Russets in Soup
Choosing russets for your potato soup comes with its own set of advantages and disadvantages.
Benefits:
- Excellent Thickening Properties: Russets break down easily, creating a naturally creamy base without the need for excessive cream or flour.
- Readily Available and Affordable: Russets are among the most widely available and budget-friendly potato varieties.
- Mild Flavor: Their subtle flavor profile allows other ingredients, such as herbs, vegetables, and bacon, to shine.
Drawbacks:
- Potential for Gluey Texture: Overcooking russets can result in a gummy or gluey consistency that detracts from the overall soup experience.
- Less Defined Chunks: They tend to disintegrate more than other potatoes, leading to a less textured soup.
- Absorbency: Russets tend to absorb a lot of liquid, requiring careful attention to broth-to-potato ratio.
Preparing Russets for Potato Soup: A Step-by-Step Guide
Here’s a suggested process for making the best potato soup using russets:
- Peel and Dice the Potatoes: Remove the skin and cut the russets into uniform cubes (about ½ to ¾ inch). Smaller pieces will cook faster, which can increase the risk of overcooking.
- Rinse the Potatoes (Optional): Rinsing the diced potatoes under cold water can remove excess surface starch, helping to minimize the potential for a gluey texture.
- Sauté Aromatics: In a large pot, sauté diced onion, celery, and carrots (mirepoix) in butter or oil until softened. This builds a flavorful base.
- Add the Potatoes and Broth: Add the diced russets to the pot and cover with chicken or vegetable broth. Ensure the potatoes are fully submerged.
- Simmer Gently: Bring the soup to a gentle simmer, then reduce the heat and cook until the potatoes are tender but not mushy. This usually takes around 15-20 minutes.
- Partial Mashing (Optional): For a balance between creamy and chunky, remove about a third of the potatoes with a slotted spoon and mash them with a fork before returning them to the pot.
- Season and Adjust: Season the soup with salt, pepper, and any desired herbs (e.g., thyme, rosemary, parsley). Adjust the broth consistency as needed.
- Add Dairy (Optional): Stir in cream, milk, or sour cream for added richness. Heat through gently, but do not boil.
- Serve and Garnish: Serve hot, garnished with bacon bits, shredded cheese, chives, or sour cream.
Common Mistakes to Avoid
Using russets in potato soup can be successful if you sidestep these common pitfalls:
- Overcooking: This is the biggest culprit of gluey soup. Test the potatoes frequently for doneness and remove from heat as soon as they are tender.
- Boiling Vigorously: Boiling can cause the potatoes to break down too quickly. A gentle simmer is key.
- Excessive Mashing: While some mashing is fine, overdoing it will create a completely smooth soup, losing the desired texture.
- Ignoring Broth-to-Potato Ratio: Too many potatoes will result in a thick, pasty soup. Add broth as needed to achieve the desired consistency.
- Adding Dairy Too Early: Dairy can curdle if added before the potatoes are fully cooked. Stir it in towards the end of the cooking process.

Frequently Asked Questions (FAQs)
1. Will russet potatoes make my potato soup too thick?
Yes, russets have a high starch content that can lead to a thicker soup. To mitigate this, rinse the diced potatoes before cooking and avoid overcooking them. You can also adjust the broth level to reach your desired consistency.
2. Can I use russet potatoes without peeling them in potato soup?
While you can leave the skins on for added nutrients and a rustic texture, be aware that russet skins are thicker than some other varieties. Leaving the skins on might also make the soup a bit less smooth. If you choose to do so, ensure the potatoes are scrubbed very well.
3. How can I prevent russet potatoes from becoming gluey in potato soup?
The key is to avoid overcooking. Cook the potatoes until they are just tender, and don’t boil them vigorously. Rinsing the potatoes before cooking also helps.
4. What’s the best way to add flavor to russet potato soup?
Start with a flavorful base by sautéing aromatics like onion, celery, and garlic in butter or bacon fat. Use a good quality chicken or vegetable broth. Don’t be afraid to use herbs and spices like thyme, rosemary, bay leaf, paprika, and garlic powder.
5. Can I freeze potato soup made with russet potatoes?
Freezing potato soup made with russets can alter the texture, making it slightly grainy upon thawing. However, it’s still possible. Consider omitting the dairy before freezing, and add it upon reheating. Also, avoid puréeing the soup before freezing, as this can exacerbate the texture changes.
6. How long does potato soup made with russets last in the refrigerator?
Potato soup made with russets will typically last for 3-4 days in the refrigerator. Ensure it is stored in an airtight container.
7. Can I use an immersion blender to blend russet potato soup?
Yes, but use it sparingly. Over-blending will result in a completely smooth soup, which may not be desirable. Pulse the blender in short bursts to achieve a slightly chunky, creamy texture.
8. What are some good toppings for russet potato soup?
The possibilities are endless! Some popular toppings include: bacon bits, shredded cheddar cheese, sour cream, chives, green onions, croutons, and a drizzle of olive oil.
9. How much broth should I use when making potato soup with russets?
This depends on your desired consistency. Start with enough broth to cover the potatoes and add more as needed. Remember that russets absorb a lot of liquid, so you may need to add more than you think.
10. Can I make potato soup with russets in a slow cooker?
Yes, you can! Add all ingredients (except dairy) to the slow cooker and cook on low for 6-8 hours or on high for 3-4 hours, or until potatoes are tender. Add dairy towards the end of the cooking time.
11. Can I use leftover baked russet potatoes for potato soup?
Yes, you can use leftover baked russet potatoes for potato soup! This can be a great way to use up leftovers. Just make sure to break them up or cube them before adding them to the soup. You might need to adjust the cooking time, as the potatoes are already cooked.
12. What kind of dairy works best in russet potato soup?
Heavy cream will create the richest and most decadent soup. Milk (whole or 2%) will provide a lighter consistency. Sour cream or crème fraîche adds a tangy flavor and creamy texture. Experiment to find your preference!
