Key takeaways
- Use high-starch russet potatoes for maximum thickening.
- Cook potatoes until very tender to ensure starch gelatinization.
- Create a smooth roux and gradually incorporate liquid to build a stable emulsion.
- Add cheese off the heat to prevent separation and maintain creaminess.
Creamy Loaded Baked Potato Soup
Ingredients
Method
- Preheat oven to 4250F. Bake pricked russet potatoes for 60-70 minutes until tender.
- Let potatoes cool, then scoop flesh into a bowl and mash. Measure 5 cups of mashed potatoes and set aside.
- Cook chopped bacon in a large pot until crisp. Remove bacon, reserving 2 tablespoons of fat.
- Add butter and onion to the pot; season with salt and pepper. Sauté until tender, then add garlic for 1 minute.
- Whisk in flour, then slowly add chicken stock and milk to create a smooth sauce. Simmer for 3-4 minutes until slightly thickened.
- Turn off heat. Whisk in half the reserved cheddar cheese, then the remaining cheese and sour cream until smooth.
- Stir in mashed potatoes and 2/3 of the cooked bacon. Taste and adjust seasoning.
- Ladle soup into bowls and top with reserved cheese, bacon, and chives or green onions.
Notes
– To ensure your soup doesn’t become grainy or clumpy, gradually add the chicken stock while whisking constantly, ensuring a smooth roux before adding the milk. Add the cheese and sour cream off the heat to prevent it from seizing.
– Storage: Leftover baked potato soup can be refrigerated in an airtight container for up to 3-4 days. Reheat gently on the stovetop over medium-low heat, stirring occasionally, or in the microwave. If it’s too thick, add a splash of milk or chicken stock to thin it out.
– For food safety, if you decide to add cooked chicken or ham to this soup, ensure it’s reheated to an internal temperature of 165°F (74°C). Nutrition information is an estimate, calculated automatically. Values vary with brands, substitutions and portion sizes.
The Technique That Makes It: Emulsification and Starch Gelatinization
The creamy texture of this baked potato soup hinges on two key culinary principles: starch gelatinization and proper emulsification. Russet potatoes, with their high starch content, are crucial. When cooked, the starch granules within the potatoes absorb liquid and swell, a process called gelatinization. This swelling releases starch into the cooking liquid, naturally thickening the soup. Boiling or simmering the potatoes until fork-tender ensures maximum starch release. After cooking, mashing or pureeing a portion of the potatoes further breaks down the cell walls, releasing even more starch and contributing to a smoother, thicker consistency. The roux, made from butter and gluten-free flour, acts as a secondary thickening agent and also aids in emulsification. When the hot liquid is gradually whisked into the roux, the starch in the flour gelatinizes, creating a stable base. The fat from the butter and the proteins from the milk help to bind the water and fat components of the soup, preventing separation and creating a smooth, cohesive, creamy texture. Adding the cheese at the end, off the heat, prevents it from breaking and becoming oily, further contributing to the soup’s velvety mouthfeel.
Troubleshooting
- Soup is too thin: If the soup isn’t thick enough after adding the potatoes and cheese, simmer it uncovered for an additional 10-15 minutes to allow excess liquid to evaporate. Alternatively, you can create a slurry with 1 tablespoon of cornstarch or gluten-free flour mixed with 2 tablespoons of cold water, then whisk it into the simmering soup until thickened.
- Soup is too thick: Gradually whisk in more milk or chicken stock, a quarter cup at a time, until the desired consistency is reached. Be careful not to add too much liquid at once.
- Soup is lumpy: This can happen if the roux wasn’t cooked properly or if the potatoes weren’t mashed/pureed smoothly. Use an immersion blender or carefully transfer the soup in batches to a regular blender to achieve a smoother consistency.
- Soup is greasy or separated: This is often due to adding cheese over high heat. Ensure the soup is at a gentle simmer (not boiling) when adding the cheese, and stir until just melted. If separation has already occurred, try whisking vigorously off the heat; sometimes a little lemon juice can help re-emulsify.
Substitutions
- Potatoes: While russets are ideal for their starch content, Yukon Golds can be used. The soup may be slightly less thick and creamy, so you might need a bit more roux or simmering time.
- Bacon: Smoked ham or pancetta can be used for a similar salty, smoky flavor. The texture will be slightly different, but the flavor profile will be complementary. For a vegetarian option, use smoked mushrooms or extra-crispy fried onions for texture and flavor.
- Milk: Evaporated milk can be used for an even richer, creamier soup, as it has a higher concentration of milk solids and less water. Non-dairy milks like unsweetened cashew or oat milk can work, but may alter the flavor and creaminess slightly.
- Cheese: A blend of cheddar and Monterey Jack or Colby cheese will provide a similar meltability and flavor. Avoid pre-shredded cheeses as they often contain anti-caking agents that can affect melting.
Pro tips
- For the crispiest bacon, cook it in a single layer without overcrowding the pan. I’ve found that starting with cold bacon in a cold pan and gradually increasing the heat yields the best results, preventing it from burning while rendering out the fat perfectly.
- To ensure your soup doesn’t become grainy or clumpy, gradually add the chicken stock while whisking constantly, ensuring a smooth roux before adding the milk. Add the cheese and sour cream off the heat to prevent it from seizing.

Frequently asked questions
What kind of potatoes are best for baked potato soup?
Russet potatoes are highly recommended due to their high starch content. This starch is essential for achieving a naturally thick and creamy soup texture when cooked and mashed or pureed.
Can I make this soup ahead of time?
Yes, this soup can be made ahead and reheated. Store it in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop over low heat, stirring frequently, and add a splash of milk or broth if it has thickened too much.
How do I make the soup smoother if it’s lumpy?
If your soup has lumps, use an immersion blender directly in the pot to blend until smooth. Alternatively, carefully transfer the soup in batches to a countertop blender and process until velvety. Ensure all ingredients are well incorporated.
What can I do if my soup is too thin?
If the soup lacks thickness, simmer it uncovered for a while longer to reduce the liquid. You can also create a slurry with cornstarch or gluten-free flour and cold water, then whisk it into the simmering soup until it reaches your desired consistency.
