Why Make Potato Soup in an Instant Pot?

Traditional potato soup is not especially difficult, but it usually requires repeated stirring, careful simmering, and regular checks to see whether the potatoes have finally surrendered. An electric pressure cooker speeds up the tenderizing process and keeps the cooking environment moist and consistent.

Pressure-cooked potatoes can become tender in minutes rather than simmering for half an hour or longer. Russets are especially useful because their high starch content helps produce a thick, velvety soup without requiring an unreasonable amount of flour, cream, or culinary optimism.

A One-Pot Comfort Food Dinner

The bacon can be cooked directly in the Instant Pot using the Sauté function. The onions and garlic then cook in the bacon drippings before the broth and potatoes are added. After pressure cooking, the soup is thickened and finished in the same pot. That means fewer dishes, less stove cleanup, and no mysterious saucepan hiding behind the coffee maker two days later.

Which Potatoes Are Best for Potato Soup?

Russet potatoes are the best choice when you want a thick, classic potato soup. They contain plenty of starch and begin to break down as they cook, naturally giving the broth more body. They also mash easily after pressure cooking.

Yukon Gold potatoes are another excellent option. They have a naturally buttery flavor and retain slightly more structure, producing a creamier but less fluffy result. For the best balance, use half russets and half Yukon Golds. The russets thicken the soup while the gold potatoes provide tender, distinct pieces.

Red potatoes can be used when you prefer a chunkier soup because they hold their shape well. However, they release less starch, so the finished broth may require additional thickener.

Should You Peel the Potatoes?

Peeling is recommended for the smoothest, most traditional result. Russet skins can become chewy or separate from the potato flesh under pressure. However, leaving some skin on is perfectly acceptable if the potatoes are thoroughly scrubbed and you enjoy a rustic texture.

How to Make Instant Pot Potato Soup

Step 1: Prepare the Potatoes

Peel the potatoes and cut them into uniform cubes measuring approximately three-quarters of an inch. Pieces of similar size cook at the same rate. Oversized chunks may remain firm in the center, while tiny pieces can vanish into the broth like potatoes entering witness protection.

Step 2: Cook the Bacon

Select the Sauté setting on the Instant Pot. Add the chopped bacon and cook for 6 to 8 minutes, stirring occasionally, until browned and crisp.

Use a slotted spoon to transfer the bacon to a paper towel-lined plate. Leave approximately 2 tablespoons of bacon fat in the pot. Reserve the bacon for stirring into the soup and sprinkling over each serving.

Step 3: Sauté the Aromatics

Add the diced onion to the bacon drippings. Cook for 3 to 4 minutes, stirring frequently, until softened. Add the garlic and cook for approximately 30 seconds, just until fragrant.

Garlic cooks quickly, so do not wander away to reorganize the refrigerator. Burned garlic has a remarkable ability to make an entire dinner taste disappointed.

Step 4: Deglaze the Inner Pot

Pour in approximately 1 cup of the chicken broth. Scrape the bottom of the pot thoroughly with a wooden spoon to release any browned bits.

This step adds flavor and helps prevent the Instant Pot from displaying a burn warning. Make sure no cooked onion, garlic, or bacon residue remains stuck to the bottom.

Step 5: Pressure Cook the Potatoes

Add the remaining broth, cubed potatoes, salt, black pepper, thyme, and smoked paprika. Stir gently.

Secure the lid and set the pressure valve according to your model’s instructions. Cook on High Pressure for 8 minutes. Remember that the displayed cooking time begins only after the pot reaches pressure, which can take 10 to 15 minutes depending on the temperature and volume of the ingredients.

Step 6: Release the Pressure Carefully

Allow the pressure to release naturally for 10 minutes. Then carefully release the remaining pressure according to the manufacturer’s directions.

A brief natural release is helpful with starchy, liquid-heavy foods because it allows the bubbling inside the pot to settle before the valve is opened. Never place your face or hand directly over the steam valve, and always follow the safety guidance for your specific pressure cooker model.

Step 7: Create the Perfect Texture

Open the lid and use a potato masher to mash roughly one-third to one-half of the potatoes directly in the broth. Leave plenty of chunks intact.

This partial-mashing method thickens the soup while preserving a satisfying texture. For a smoother soup, use an immersion blender for only a few short pulses. Avoid blending aggressively because overworked russet potatoes can become pasty.

Step 8: Add the Creamy Ingredients

In a small bowl, whisk the cornstarch into the cold milk until completely smooth. Select the Sauté function and stir the milk mixture into the soup.

Simmer gently for 2 to 4 minutes, stirring frequently, until the broth thickens. Do not allow it to boil vigorously.

Turn off the heat. Stir in the heavy cream, cheddar cheese, sour cream, and half of the cooked bacon. Continue stirring until the cheese melts and the soup becomes smooth.

Adding milk, cream, cheese, and sour cream after pressure cooking provides better control over the final consistency and helps keep the dairy smooth. Several established pressure-cooker potato soup methods follow this finish-after-cooking approach.

Step 9: Taste and Serve

Taste the soup and add more salt or pepper as needed. Ladle it into warm bowls and finish with cheddar, bacon, green onions, sour cream, or your favorite baked-potato toppings.

How to Adjust the Thickness

If the Soup Is Too Thin

Mash more of the potatoes and let the soup simmer uncovered on the Sauté setting for several minutes. You can also mix 1 additional tablespoon of cornstarch with 2 tablespoons of cold milk, then stir it gradually into the soup.

Always mix cornstarch with a cold liquid before adding it. Pouring dry cornstarch directly into hot soup is an efficient way to create tiny white dumplings that nobody requested.

If the Soup Is Too Thick

Stir in warm chicken broth or milk, a few tablespoons at a time, until the desired consistency is reached. Potato soup continues to thicken as it cools, so leave it slightly looser than you think it needs to be.

Easy Potato Soup Variations

Ham and Potato Soup

Replace the bacon with 1 1/2 cups of diced cooked ham. Add the ham after pressure cooking so it warms through without becoming tough. This is an excellent use for leftover holiday ham.

Vegetarian Instant Pot Potato Soup

Omit the bacon and sauté the onion in 2 tablespoons of butter or olive oil. Replace the chicken broth with vegetable broth. Add a pinch of smoked paprika for extra depth.

Dairy-Free Potato Soup

Use olive oil instead of bacon fat, unsweetened dairy-free milk instead of whole milk, and full-fat canned coconut milk instead of heavy cream. Choose a neutral dairy-free cheese or omit the cheese entirely. More mashed potatoes can supply additional body without dairy.

Broccoli Cheddar Potato Soup

After pressure cooking, stir in 2 cups of finely chopped broccoli. Simmer on the Sauté setting until the broccoli is tender, then add the milk, cheese, and remaining finishing ingredients.

Spicy Southwest Potato Soup

Add one diced jalapeño with the onion and replace the thyme with cumin. Finish the soup with pepper jack cheese, cilantro, corn, avocado, and crushed tortilla chips.

What to Serve With Potato Soup

This creamy Instant Pot potato soup is filling enough to serve as a complete meal, especially after the bacon and cheese become involved. A fresh side dish, however, creates a useful contrast to the rich broth.

• A crisp green salad with vinaigrette
• Roasted broccoli or Brussels sprouts
• Garlic bread or warm dinner rolls
• A grilled cheese sandwich
• Apple and walnut salad
• Roasted chicken or turkey sandwiches

Storing and Reheating Leftover Potato Soup

Refrigerating

Transfer leftover soup to shallow airtight containers and refrigerate it within two hours of cooking. Properly refrigerated soups and stews generally keep for 3 to 4 days. Dividing a large batch into smaller containers helps it cool more quickly.

Reheating

Reheat the soup gently in a saucepan over medium-low heat, stirring frequently. Add a splash of broth or milk because the potatoes will absorb liquid during storage.

Individual portions can be microwaved in short intervals, stirring between each interval to distribute the heat evenly.

Can You Freeze Potato Soup?

Potato soup can be frozen, but dairy-based versions may separate slightly and potato pieces can become grainier after thawing. For better freezer results, prepare the soup through the pressure-cooking stage, cool it, and freeze it before adding the milk, cream, sour cream, and cheese.

Thaw the soup in the refrigerator, reheat it gently, and add the dairy ingredients just before serving.

Common Instant Pot Potato Soup Problems

The Instant Pot Displays a Burn Warning

The bottom of the inner pot may not have been fully deglazed. Turn off the cooker, release pressure safely, and inspect the bottom. Transfer the contents temporarily if necessary, clean away the stuck residue, add a little extra broth, and restart the cooking cycle.

The Potatoes Are Still Firm

The cubes may have been too large, or the pot may not have maintained full pressure. Secure the lid and pressure cook for an additional 2 minutes, followed by a 5-minute natural release.

The Soup Tastes Bland

Potatoes absorb a surprising amount of seasoning. Add salt gradually, then brighten the flavor with black pepper, green onions, sharp cheddar, or a small squeeze of lemon juice. Bacon and broth also vary considerably in saltiness, so final seasoning should always happen after the soup is assembled.

The Soup Became Gummy

Excessive blending can rupture too many potato starch cells and produce a gluey texture. Use a masher or pulse an immersion blender briefly rather than processing the entire batch until perfectly smooth.

Frequently Asked Questions

Can I Put Raw Bacon in the Soup Before Pressure Cooking?

You can, but browning it first produces better flavor and gives you crisp pieces for topping. Bacon cooked entirely in liquid becomes soft rather than crisp.

Can I Use Frozen Potatoes?

Frozen diced potatoes can work, although the final texture may be softer. Add them directly from the freezer and use the same pressure-cooking time. Avoid frozen hash browns unless you want an almost completely smooth soup.

Can I Double the Recipe?

Doubling may be possible in a larger pressure cooker, but the ingredients must remain below the maximum fill line. Do not double the cooking time. The pot will simply take longer to reach pressure.

Can I Make the Soup Without Bacon?

Absolutely. Butter creates a rich base, while olive oil provides a lighter option. A little smoked paprika, nutritional yeast, or sautéed mushrooms can replace some of bacon’s savory character.

Why Is the Pressure-Cooking Time Only Eight Minutes?

The potatoes begin cooking while the Instant Pot comes to pressure and continue cooking during the natural-release period. The complete cooking process is therefore longer than the number shown on the display.

Experience Notes: What I Learned Making Instant Pot Potato Soup

The first lesson from making pressure-cooker potato soup is that preparation matters more than an extra minute on the timer. When the potato cubes vary wildly in size, the smallest pieces dissolve while the largest pieces remain suspiciously crunchy. Cutting three-quarter-inch cubes takes a few extra minutes, but it creates a much more predictable result.

I also learned not to underestimate the deglazing step. After cooking bacon and onions, the bottom of the pot may look merely “nicely browned.” The Instant Pot, however, can interpret those flavorful browned bits as the beginning of a kitchen emergency. Adding broth and scraping until the bottom feels completely smooth prevents most burn notices.

My early batches also included milk before pressure cooking. Although the soup was edible, the dairy occasionally looked separated and the bottom of the pot was harder to clean. Finishing the soup with milk, cream, sour cream, and cheese after pressure cooking produced a smoother texture and gave me more control over the richness.

The biggest improvement came from abandoning the goal of blending every potato into submission. A completely blended russet soup can become overly thick or slightly gummy, especially after it sits. Mashing about one-third of the potatoes gives the broth enough starch while leaving plenty of soft chunks. Each spoonful then feels like potato soup rather than unusually savory wallpaper paste.

Cheese selection matters as well. Pre-shredded cheese is convenient, but it is often coated with anti-caking ingredients that can keep it from melting smoothly. Freshly grated sharp cheddar melts more evenly and contributes stronger flavor, which means less cheese can accomplish more. Stirring it in after turning off the heat also reduces the chance of a greasy or grainy finish.

I have found that the soup should look slightly thinner in the Instant Pot than I ultimately want it. Within 10 minutes of resting, the starch continues absorbing broth. A soup that appears perfect immediately can become thick enough to hold a spoon upright by the time everyone reaches the table. Keeping warm broth nearby makes last-minute adjustments simple.

Toppings transformed this recipe from a plain bowl of soup into a dinner people actively requested again. Crispy bacon and cheddar are obvious choices, but chopped green onions provide necessary freshness. A spoonful of sour cream adds tang, while hot sauce cuts through the richness. Even a simple pile of crushed crackers adds contrast.

One memorable batch taught me that seasoning must be judged at the end. Bacon, broth, cheese, and salted butter all contribute sodium. Adding too much salt before pressure cooking can produce an aggressively seasoned soup once the liquid reduces and the cheese goes in. Starting conservatively and adjusting before serving is safer.

Leftovers may be even thicker the next day, but that is not a failure. A splash of broth and slow reheating restore the original consistency. In fact, the flavors often become more integrated overnight. The bacon tastes smokier, the onion becomes less distinct, and the herbs settle comfortably into the background.

Most importantly, this recipe is forgiving. A little more potato makes it thicker. Extra broth makes it lighter. Cheddar makes it bolder, sour cream makes it tangier, and bacon makes almost everyone stop asking whether dinner is ready. Once the basic pressure-cooking method is understood, the recipe becomes a flexible formula rather than a strict set of rules.

Final Thoughts

This Instant Pot potato soup recipe combines the speed of pressure cooking with the familiar comfort of a loaded baked potato. Russet potatoes create natural thickness, sautéed onions and bacon build a savory foundation, and dairy ingredients added at the end keep the soup creamy and balanced.

Serve it on a cold evening, prepare it for a casual family dinner, or build a topping bar for a crowd. It is uncomplicated, adaptable, and satisfyingthe culinary equivalent of putting on warm socks without having to locate the matching pair.
