Ingredients and Quantities

• 2 lb (about 900 g) russet or Yukon Gold potatoes, peeled and cut into 1″ cubes
• 4–6 slices bacon, chopped (or 2 tbsp olive oil if you’re making it vegetarian)
• 1 medium onion, finely chopped
• 2 cloves garlic, minced
• 2 tbsp unsalted butter
• 2 tbsp all-purpose flour
• 4 cups (1 L) chicken or vegetable broth
• 1 cup (240 ml) whole milk or half-and-half (cream works great for extra richness)
• 1 cup (100 g) sharp cheddar cheese, grated
• 1/2 cup (120 g) sour cream (optional but highly recommended!)
• Salt and freshly ground black pepper, to taste
• 2–3 tbsp chopped chives or green onions for garnish

How to Make It

1. Peel potatoes and cut into 1-inch cubes.
2. Chop bacon into pieces (or measure 2 tbsp olive oil for vegetarian).
3. Finely chop the onion and mince the garlic.

4. Grate the sharp cheddar and chop chives or green onions.

   

5. Heat a large heavy-bottomed pot over medium and cook bacon until crisp; remove with a slotted spoon and drain, leaving 1–2 tbsp bacon fat in the pot (or heat 2 tbsp butter/olive oil if vegetarian).
6. Sauté the chopped onion in the reserved fat until soft and translucent, about 5–7 minutes.
7. Add the minced garlic and cook 30–60 seconds until fragrant.

8. Add 2 tbsp butter if using, sprinkle 2 tbsp flour over the onion–garlic mixture, and stir constantly for 1–2 minutes to cook off the raw flour taste.

   

9. Slowly pour in 4 cups broth while whisking to keep the mixture smooth and lump-free.
10. Add the potato cubes, bring to a gentle boil, then reduce heat and simmer until potatoes are fork-tender, about 12–15 minutes.
11. Mash about one-third of the potatoes in the pot with a spoon or pulse a few times with an immersion blender to thicken while retaining some chunks.

12. Warm the milk or half-and-half slightly (or remove the pot from heat) and stir it into the soup, warming through without boiling.

13. Remove the pot from heat and stir in the grated cheddar until melted; fold in sour cream if using.

14. Taste the soup and season with salt and freshly ground black pepper as needed.

    

Expert Tips for Best Results

• Pick your potato wisely: Russets will give you a thicker, fluffier soup when partially mashed (their high starch is the same reason they make superior hash browns), while Yukon Golds add a natural buttery creaminess.
• Grate your own cheese: Pre-shredded cheese often melts unevenly because of anti-caking agents. Freshly grated sharp cheddar melts beautifully for that silky texture—much like in classic gougères.
• Add dairy carefully: To stop sour cream or milk from curdling, stir them in off the heat or warm them slightly before adding to the hot soup.
• Too thin? Too thick? If your soup feels watery, simmer uncovered for a bit to reduce it or stir in a small mixture of flour or cornstarch with cold water. If too thick, loosen it with extra broth or milk until just right.
• Control creaminess with your blender: Use an immersion blender to pulse a few times, so you keep some potato chunks for texture instead of making it too smooth.
• Season bit by bit: Potatoes tend to soak up salt, so taste as you go and adjust seasonings at the end to get it just right.

Delicious Variations and Swaps

• Vegetarian: Skip the bacon and use olive oil instead. Add smoky depth with smoked paprika or a splash of liquid smoke plus some sautéed mushrooms for a rich twist.
• Ham & Cheddar: Swap the bacon for diced cooked ham to make a heartier, protein-packed soup your family will love. Serve with warm puff pastry cheese pockets for extra cheesy comfort.
• Loaded Baked Potato Style: Stir in steamed corn kernels and top with extra sour cream and green onions for a sweet, Tex-Mex inspired twist.
• Vegan Option: Replace butter with oil, use vegetable broth and unsweetened plant milk like oat or soy. Use dairy-free cheese and coconut yogurt for creaminess. For added plant-based protein on the side, try a one-pan roasted carrot and chickpea bowl.
• Crockpot Friendly: Brown bacon and sauté onion on the stove first, then transfer everything to your slow cooker. Cook on low for 4–5 hours or high for 2–3 hours until potatoes soften. Finish with milk and cheese off heat.

Storing, Freezing, and Reheating

• Refrigerating: Let the soup cool completely, then store it in an airtight container in the fridge for up to 3–4 days. Perfect for leftovers or prepping ahead.
• Freezing: For best results, leave out the sour cream and extra milk before freezing. Cool the soup, portion into freezer-friendly containers, and freeze for up to 2–3 months. Thaw overnight in the fridge before reheating. For a naturally dairy-free make-ahead bowl that freezes beautifully, try Sweet Potato and Chickpea Curry.
• Reheating: Warm gently on the stove over low heat, stirring often. Add a splash of broth or milk if it’s too thick. You can microwave it too—just heat in short bursts and stir between to avoid hot spots.
• Make-ahead magic: The flavors in this soup actually get better the next day once they meld together. Reheat and add cheese and sour cream right before serving for the best taste and texture. For more soups that reheat well, explore our Best Soup Recipes for winter.

Answers to Common Questions

• Can I use leftover mashed potatoes? Absolutely! Just thin the mashed potatoes with some broth or milk and warm gently. Keep in mind the soup will be smoother, so check seasoning and adjust if needed.
• How do I keep potatoes from falling apart? Simmer gently until tender but not mushy. Avoid a rolling boil which can break them down too much. Mash only after most of the cooking is done. For a step-by-step look at potatoes that stay tender yet hold their shape, see the Spanish Tortilla technique.
• Is this soup easy to make dairy-free? Yes! Use plant-based milk like oat or soy and swap butter for oil. You can also use dairy-free cheese or leave it out and stir in nutritional yeast for extra flavor.
• Why did my soup turn grainy after adding cheese? That usually happens if the soup is too hot when you add cheese or if you use pre-shredded cheese. Always remove from heat first, shred cheese fresh from a block, and stir gently to melt.
• How can I fix the soup if it’s too thick or too thin? To thicken, simmer uncovered to reduce, mash more potatoes, or stir in a small slurry of cornstarch or flour mixed with water. To thin it out, add warm broth or milk little by little until it’s just right.
