Ingredients for baked potato soup recipe easy with milk
Six ingredients transform simple potatoes into creamy restaurant-style perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 3 lb | Peeled and cubed evenly |
| Whole Milk 🥛 | 2 cups | Whole milk for creaminess |
| Chicken Broth 💧 | 4 cups | Low-sodium preferred |
| Yellow Onion 🧅 | 1 whole | Diced into small pieces |
| Garlic Cloves 🧄 | 4 cloves | Roasted for depth of flavor |
| Sharp Cheddar Cheese 🧀 | 1 cup | Shredded, aged variety |
| Butter 🧈 | 4 tbsp | Unsalted for flavor control |
| All-Purpose Flour 🌾 | 2 tbsp | For thickening roux |
| Salt 🧂 | 1 ½ tsp | Kosher salt preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Dried Thyme 🌿 | ½ tsp | Or 1 tsp fresh thyme |
| Sour Cream 🥛 | ½ cup | For garnish (optional) |
| Green Onions 🧅 | 3 whole | Sliced for garnish |
| Crispy Bacon Bits 🥓 | ¼ cup | For garnish (optional) |
The potatoes are the foundation—Russet potatoes are ideal for their high starch content, which creates that signature velvety texture when blended. Peeled and cubed evenly, they cook uniformly and break down smoothly. For the milk, whole milk is essential for that luxurious creaminess (skim won’t cut it). I always grab organic milk from Whole Foods or the store brand at Trader Joe’s—both work perfectly. The chicken broth should be low-sodium to control flavor; Swanson or Pacific Foods are my go-tos, but homemade works even better. Roasting the garlic before adding it to the soup deepens its flavor—don’t skip this step—it’s what elevates this soup from basic to restaurant-worthy.
No whole milk? Half-and-half or heavy cream will work in a pinch, though the texture will be slightly richer. The cheddar should be sharp and aged—Cabot or Pepper Ridge are my favorites, but any good-quality sharp cheddar will do. For the roux, all-purpose flour is fine, but if you’re feeling fancy, cornstarch creates an even silkier finish. The dried thyme can be swapped for fresh thyme at double the amount, but since we’re keeping this simple, dried works perfectly. If you’re avoiding dairy, cashew cream (blended soaked cashews) can replace the milk, though the texture will differ slightly. For the garnish, sour cream adds a tangy contrast, while green onions and bacon bits bring extra layers of flavor.
This soup reheats beautifully—taste even better the next day as the flavors meld. Store leftovers in an airtight container in the fridge for up to 5 days, or freeze for 3 months. To reheat, warm on the stove over medium-low heat, stirring occasionally, and add a splash of milk or broth if it thickens too much. For meal prep, double the batch and freeze in 2-cup portions—just thaw overnight in the fridge before reheating. The bacon bits and green onions can be added fresh after reheating to keep them crisp.

Step-by-step instructions for creamy baked potato soup
This velvety soup comes together effortlessly with simple techniques and minimal effort.
Roast the Potatoes and Aromatics for Depth of Flavor
Preheat your oven to 400°F. On a large baking sheet, toss the 3 lb Russet Potatoes (cubed evenly), 1 whole Yellow Onion (diced), and 4 cloves Garlic Cloves (peeled) with 2 tbsp olive oil, 1 tsp salt, and 0.25 tsp black pepper. Spread them in a single layer, ensuring the potatoes aren't crowded.
Roast for 30-35 minutes, stirring once halfway through, until the potatoes are tender when pierced with a fork and the edges begin to brown. The roasting caramelizes the natural sugars in the potatoes and onions, creating a rich, sweet foundation for your soup. This step builds flavor that simmering alone can't match.
Build the Roux for Silky Texture
While the potatoes roast, melt 4 tbsp Butter in a large Dutch oven or heavy pot over medium heat. Whisk in 2 tbsp All-Purpose Flour and cook for 1-2 minutes until the mixture turns a light golden color and smells nutty. This roux forms the base of your soup's velvety texture.
Carefully pour in 4 cups Chicken Broth all at once, whisking constantly to prevent lumps. Bring to a simmer and cook for 3-4 minutes until slightly thickened. Here's the thing—don't rush this step. A proper roux ensures your soup won't be watery, even with the milk added later.
Combine and Simmer for Creamy Perfection
Add the roasted potatoes, onions, and garlic to the pot. Stir in 2 cups Whole Milk, 1.5 tsp Salt, 0.5 tsp Black Pepper, and 0.5 tsp Dried Thyme. Bring to a gentle boil, then reduce heat to medium-low and let it simmer for 10-12 minutes, stirring occasionally, until the potatoes are completely tender and falling apart.
Use an immersion blender to purée the soup directly in the pot until completely smooth. If you prefer some texture, blend only half and leave the rest chunky. The soup should be thick and creamy—if it's too thick, whisk in 2-4 tbsp hot water to reach your desired consistency. This blending step transforms your roasted vegetables into a luxurious, velvety base.
Finish with Cheese and Garnishes
Remove the pot from heat and stir in 1 cup Sharp Cheddar Cheese until completely melted and smooth. Taste and adjust seasoning with additional salt and pepper if needed. Ladle the soup into bowls and top each serving with 2 tbsp Sour Cream, 1 whole Green Onion (sliced), and 1 tbsp Crispy Bacon Bits.
Serve immediately while hot. The contrast between the creamy soup and the cool, crisp bacon bits creates the perfect textural experience. This final step elevates your soup from good to exceptional with just a few simple garnishes that add layers of flavor and visual appeal.
Pro Tips For Making Baked Potato Soup Recipe Easy With Milk
- PEEL AND CHOP POTATOES SMALL: Russets break easily when boiled—cut them into 1-inch chunks instead of thick slices. I learned this the hard way when my first batch turned to mush because I was lazy with the knife. Small pieces cook evenly and hold their shape.
- SWEAT ONIONS LOW AND SLOW: Cook the onion in butter or oil over medium-low heat until it’s translucent but not browned—this builds flavor without bitterness. I used to rush it and ended up with a soup that tasted like raw onion. Patience here makes a real difference.
- USE FULL-FAT MILK: Whole milk adds creaminess without curdling, but skim or low-fat versions can separate when simmered. I was skeptical until I tried it—full-fat milk makes the soup richer and smoother, especially when blended.
- BLEND IN BATCHES: If your soup is thick, blend it in two stages: first, blend half the soup until smooth, then mix it back in before blending the rest. This keeps the texture consistent and prevents clumps. I skip this when I’m lazy, but the dish is noticeably better when I don’t.

For a fiber boost, I sometimes stir in 1 tablespoon of oat bran during the blending step—it thickens the soup naturally and adds extra nutrients. 🌱
Low-Fat Option
If you’re watching your saturated fat intake, swap the whole milk for skim milk and use low-fat cheddar cheese to cut calories while keeping the creamy texture. The bacon bits can be omitted or replaced with turkey bacon for a leaner option.

Nutrition facts
Frequently asked questions
Can I make this baked potato soup without dairy?
Replace the whole milk with cashew cream (blend soaked cashews with water) and use nutritional yeast instead of cheddar for a cheesy flavor. The texture will be slightly lighter but still creamy. For extra richness, add 1 tbsp olive oil at the end.
Why does my soup turn out watery?
Watery soup usually means the potatoes weren't cooked long enough or the roux wasn't developed properly. Always roast potatoes until tender (30-35 minutes) and cook the roux for 1-2 minutes until golden. If needed, simmer uncovered for 5 extra minutes to reduce liquid. A splash of cornstarch slurry can also help thicken it quickly.
Can I use sweet potatoes instead of Russets?
Yes, but the flavor and texture will differ. Sweet potatoes add natural sweetness and a slightly orange hue, while Russets create a more neutral, earthy base. For best results, use 1 lb sweet potatoes plus 2 lb Russets to balance flavors. The roasting time stays the same (30-35 minutes), but check for doneness earlier as sweet potatoes cook faster.
How do I fix lumps in my blended soup?
Lumps happen when the roux isn't fully incorporated or the soup isn't hot enough during blending. First, stir vigorously with a whisk to break up chunks. For stubborn lumps, blend again with an immersion blender or transfer to a countertop blender. If all else fails, mash a few cooked potatoes with a fork and stir them in—they'll help emulsify the soup.
Is this soup kid-friendly?
Yes! Kids usually love the creamy texture and mild flavors. For picky eaters, blend until completely smooth and serve with buttered bread cubes or crushed crackers for dipping. Skip the bacon bits if preferred, and adjust seasoning to be milder. The milk and cheese make it naturally appealing to children.
