Potato Soup with Frozen Potatoes: Easy Recipe & Tips

Yes, you can absolutely make delicious potato soup using frozen potatoes as a convenient substitute for fresh. Frozen potatoes work well in soups when properly incorporated—they save prep time while maintaining flavor and texture. The key is to add them at the right stage of cooking and adjust liquid content to account for their higher moisture. This guide provides a proven method for creating creamy, satisfying potato soup with frozen potatoes as the star ingredient.

Why Frozen Potatoes Work Well in Soup

Many home cooks wonder can you use frozen potatoes in soup without compromising quality. The answer is yes—with proper technique. Frozen potatoes have been pre-cooked (blanched) before freezing, which means they require less cooking time than fresh potatoes. This actually benefits soup preparation by reducing overall cooking time while maintaining structure.

When selecting frozen potatoes for soup, choose frozen diced potatoes or frozen sliced potatoes rather than hash browns, which often contain added oils or seasonings that can affect your soup's flavor profile. High-quality frozen potatoes maintain their integrity during cooking, preventing the soup from becoming overly starchy or mushy.

Key Considerations for Potato Soup with Frozen Potatoes

The main difference between using fresh and frozen potatoes is moisture content. Frozen potatoes release more water as they thaw, which affects the soup's consistency. Here's how to adjust:

Factor	Fresh Potatoes	Frozen Potatoes
Prep Time	15-20 minutes (peeling, chopping)	0 minutes (ready to use)
Cooking Time	20-25 minutes to soften	10-15 minutes to heat through
Moisture Content	Stable	Releases water as it thaws
Texture Result	Firm when properly cooked	Softer, may break down more

Perfect Potato Soup Recipe Using Frozen Potatoes

This easy potato soup with frozen potatoes recipe yields a creamy, flavorful soup in under 30 minutes. The secret is in the timing and liquid adjustments.

Ingredients

2 tablespoons butter or olive oil
1 medium onion, finely chopped
3 cloves garlic, minced
3 cups chicken or vegetable broth
2 cups frozen diced potatoes (not thawed)
1 cup heavy cream or half-and-half (optional for creaminess)
½ cup shredded cheddar cheese (optional)
4 strips cooked bacon, crumbled (plus extra for garnish)
Salt and pepper to taste
1 teaspoon dried thyme
2 green onions, sliced (for garnish)

Step-by-Step Instructions

Sauté aromatics: In a large pot, melt butter over medium heat. Add onions and cook until translucent (about 5 minutes). Add garlic and cook for 1 minute until fragrant.
Add broth and seasonings: Pour in broth, thyme, salt, and pepper. Bring to a gentle simmer.
Incorporate frozen potatoes: Add frozen diced potatoes directly to the simmering broth—do not thaw first. This prevents them from becoming waterlogged. Simmer for 10-12 minutes until potatoes are heated through and tender.
Adjust consistency: If the soup seems too thin, create a slurry by mixing 2 tablespoons cornstarch with ¼ cup cold water. Stir into soup and simmer for 2 minutes until thickened. If too thick, add additional broth ¼ cup at a time.
Add cream and cheese: Reduce heat to low. Stir in cream and cheddar cheese until melted and incorporated.
Finish with bacon: Add crumbled bacon and simmer for 2 more minutes.
Serve: Ladle into bowls and garnish with additional bacon and green onions.

Troubleshooting Common Issues

When making potato soup with frozen potatoes, these problems sometimes occur:

Problem: Soup is too watery

Solution: Frozen potatoes release moisture as they thaw. To prevent this, reduce broth by ½ cup from the beginning, or create a cornstarch slurry as mentioned in the recipe. Simmer uncovered for 5-10 minutes to evaporate excess liquid.

Problem: Potatoes become mushy

Solution: Overcooking is the main culprit. Frozen potatoes only need 10-12 minutes in simmering liquid. Add them later in the cooking process than you would fresh potatoes. Choose frozen diced potatoes labeled "for boiling" rather than "for mashing" for better texture retention.

Problem: Flavor is diluted

Solution: Because frozen potatoes add water to the soup, boost flavor by using concentrated broth, adding an extra clove of garlic, or including a Parmesan rind while simmering. The rind adds umami without making the soup cheesy.

Pro Tips for the Best Frozen Potato Soup

Don't thaw first: Adding frozen potatoes directly to hot liquid helps maintain their structure
Layer flavors: Sauté onions and garlic thoroughly before adding liquids for deeper flavor
Acid balance: A splash of white wine or lemon juice at the end brightens the rich flavors
Texture contrast: Reserve ½ cup of cooked potatoes, mash slightly, and stir back in for varied texture
Freezer-friendly: This time-saving potato soup recipe freezes well for up to 3 months

Storage and Reheating Instructions

Store cooled soup in airtight containers for up to 4 days in the refrigerator. When reheating creamy potato soup with frozen potatoes, do so gently over medium-low heat to prevent separation. If the soup has thickened in storage, add a splash of broth or cream while reheating.

For best results when freezing, omit dairy ingredients and add them when reheating. Frozen soup maintains quality for 2-3 months. Thaw overnight in the refrigerator before reheating.

Frequently Asked Questions

Can I use frozen hash browns instead of diced potatoes for potato soup?

Yes, but with adjustments. Frozen hash browns contain more starch and often have added seasonings. Rinse them under cold water to remove excess starch before adding to your soup, and reduce additional salt in the recipe since hash browns are typically pre-seasoned. Add them during the last 5-7 minutes of cooking to prevent disintegration.

Do I need to thaw frozen potatoes before adding them to soup?

No, adding frozen potatoes directly to simmering broth works best. Thawing them first releases too much water and can make the potatoes mushy. The gradual heating from frozen to cooked temperature helps maintain their structure in the soup.

How can I prevent my potato soup from becoming gluey when using frozen potatoes?

To avoid a gluey texture, don't overcook the potatoes (10-12 minutes is sufficient), use a gentle simmer rather than a rolling boil, and avoid excessive stirring once the potatoes are added. If using high-starch frozen potatoes, rinse them briefly under cold water before adding to remove surface starch.

What's the best type of frozen potato to use for creamy potato soup?

For creamy potato soup, choose frozen diced potatoes labeled "for boiling" or "for soups." These varieties maintain their shape better than those labeled "for mashing." Russet or Yukon Gold frozen potatoes work particularly well, with Yukon Gold providing a naturally creamier texture due to their buttery flesh.

Can I make this potato soup recipe dairy-free using frozen potatoes?

Absolutely. For a dairy-free version of this frozen potato soup preparation, substitute coconut milk or cashew cream for dairy cream. You can also blend 1 cup of cooked cauliflower with 1 cup of broth and stir it into the soup for creaminess without dairy. The frozen potatoes will still provide excellent texture and flavor in the dairy-free version.
