Ingredients Needed
- Onion – about ½ to 1 yellow or sweet onion, diced. Yellow onions are preferred for this recipe.
- Salt & black pepper – to taste; start with about 1 teaspoon kosher salt and ¼ teaspoon black pepper and adjust.
- Broth – 4 cups chicken or vegetable broth works well.
- Potatoes – russet potatoes are ideal for a thick, creamy texture; use about 4 cups peeled and cubed (roughly 2 medium potatoes).
- Sour cream – about ⅓ cup to add creaminess and a touch of tang.
- Optional: garlic and bacon for extra flavor, or use plant-based bacon to keep the soup vegetarian.
Instructions
- Heat a large saucepan over medium heat. Add the diced onion (and minced garlic and cooked bacon if using). Sauté until the onion softens, then add salt and pepper and cook for another minute.
- Pour in the broth, scrape any browned bits from the bottom of the pan, then add the cubed potatoes. Bring to a boil, reduce heat, and simmer about 10 minutes or until the potatoes are tender.
- Remove the pot from the heat. Carefully transfer about 3 cups of the soup to a blender and puree until smooth, or use an immersion blender and pulse directly in the pot until mostly blended.
- Return the blended soup to the saucepan, stir in the sour cream, and heat for another 5 minutes until hot. Adjust seasonings, serve with desired toppings, and enjoy.
FAQs
Russet or Idaho potatoes are best for a creamy, blended soup because they break down and thicken nicely. If you prefer a chunkier soup, use red potatoes or Yukon Gold, which hold their shape better.
Common toppings include bacon bits, diced ham, chopped chives or green onions, shredded cheddar, croutons, sour cream, or herbs. Choose whatever you like for added texture and flavor.
Store leftover soup in an airtight container in the refrigerator for 3–5 days.
Freezing is possible but can change the texture, making it slightly grainy once thawed. If you freeze it, use within a month and reheat gently, stirring well.
Other Helpful Tips
- Use a plant-based bacon if you want a smoky flavor while keeping the soup vegetarian.
- Blend to your preferred consistency: full smoothness with a blender, or a slightly chunky texture with an immersion blender.
- Reheat gently in the microwave or on the stovetop over medium heat to avoid breaking the texture.
This easy potato soup makes a comforting lunch or dinner. Serve with a salad or crusty bread for a complete meal. It’s simple, satisfying, and perfect whenever you need a warm, cozy dish.
Variations
- Use butter and whole milk instead of some broth and sour cream for an ultra-creamy version.
- Replace part of the potatoes with riced cauliflower for a lighter, lower-carb option.
- Use nutritional yeast for a cheesy flavor in a vegan version.
- Add celery, rosemary, or thyme while sautéing onions to deepen the flavor.
- Stir in a splash of heavy cream or a bit of cream cheese for extra richness.
Suggested Side Dishes
This soup pairs well with simple sides like steamed or roasted green beans, a crisp cucumber salad, or a green salad. For a special meal, serve with roasted asparagus wrapped in bacon or a warm crusty loaf.
