The moment a knife slides into the center of a russet without resistance, you know the potatoes are ready for soup. I bake them whole, then let them cool just enough to peel and cut without burning my hands. That gives Saltgrass Baked Potato Soup its tender potato chunks without turning the pot into a mash.
The soup gets its body from a quick butter-and-flour roux, not from cooking the potatoes down in the broth. I whisk in the broth and half-and-half gradually, then let the base thicken before adding the potatoes. A gentle finish keeps those cubes recognizable, with bacon folded through the soup and crisp pieces, cheddar, and green onions waiting for the bowls.
Kitchen Note
I hold back two slices of bacon for the bowls before stirring the rest into the soup. They stay crisp on top instead of softening in the hot broth.

Why the Potatoes Go In After the Broth Has Thickened
Potato soup can turn pasty when the potatoes spend the whole cooking time breaking down in the pot. Here, the broth and half-and-half thicken first with a roux, so the potatoes only need a short, gentle simmer at the end. They warm through and share their starchy flavor without dissolving into the base.
Baking the russets whole also keeps water from clinging to peeled potato pieces before they reach the soup. That matters in a creamy broth: extra moisture can thin the base, while a baked potato brings a soft, fluffy center that blends naturally with the roux. Cut the potatoes into even pieces, then stir them in once the soup is already slightly thickened. The result has a creamy spoonful with distinct potato chunks, rather than a gluey pot where the texture is hard to control.
The Ingredients That Keep This Soup Rich, Not Heavy
- Russet potatoes — Their fluffy interiors give the soup its familiar baked-potato texture. Choose firm potatoes without soft spots; russets are usually an inexpensive, reliable choice. Baking them whole before cutting is what gives the pieces a tender center without adding water to the soup.
- Bacon — It brings smoky, salty flavor and gives the topping its crisp bite. Any standard bacon you enjoy works; the pieces should be cooked until crisp before you save some for the bowls. Since the rendered fat is discarded, the butter—not bacon grease—forms the roux.
- Butter and all-purpose flour — Together they thicken the broth and half-and-half into a smooth base. Unsalted butter lets you season the soup with more control. For a gluten-free version, use a measure-for-measure gluten-free all-purpose flour blend as described below.
- Half-and-half — This gives the broth more body than milk without making it as rich as a cream-only base. Whole milk works if that is what you have, though the soup will be thinner; a mix of whole milk and heavy cream in equal parts is closer to half-and-half.
- Sour cream — It adds the tang that keeps the creamy base from tasting flat. Full-fat plain Greek yogurt can stand in, but it tastes tangier and is more likely to turn grainy if overheated, so stir it in off the heat.
- Sharp cheddar and green onions — Sharp cheddar gives the topping enough flavor to stand up to the potatoes and cream. If you have a block, shredding it yourself gives a softer, less dusty melt than many pre-shredded cheeses. Slice the green onions thinly so their fresh bite is spread through each bowl.
How to Build the Soup Without Losing the Potato Chunks
Bake the Russets Until a Knife Slides In Easily
Heat the oven to 400°F and scrub and dry the potatoes. Prick each potato several times with a fork, then bake them on a rimmed baking sheet for 50 to 60 minutes. They are ready when a knife slides easily into the centers; if the middle still feels firm, give them more time. Let them cool until easy to handle, about 15 minutes, then peel and cut them into 1/2-inch pieces.
Cook the Bacon and Save the Crisp Topping
Set a 6-quart Dutch oven over medium heat and cook the chopped bacon for 8 to 10 minutes, stirring occasionally. Look for crisp, browned pieces rather than soft, pale bacon. Transfer it to a paper towel-lined plate and reserve about two slices for topping. Discard the bacon fat and wipe out the pot so the butter and flour can make a clean, creamy base.
Whisk the Roux Until the Base Is Smooth
Melt the butter in the Dutch oven over medium heat, then whisk in the flour. Cook the mixture for 1 minute, whisking so no dry flour remains. Gradually pour in the chicken broth and half-and-half while whisking; adding the liquids slowly helps prevent lumps. Add the salt and pepper, bring the soup to a gentle simmer, and cook for 5 to 8 minutes, whisking often, until it looks slightly thickened.
Warm the Potatoes and Bacon Gently
Stir in the cut potatoes and the bacon that was not reserved for topping. Keep the pot at a gentle simmer for 5 minutes, just long enough to warm the pieces through. Avoid a hard boil, which can break up the potatoes and make the creamy base rough. Once the soup is heated through, take the pot off the heat.
Finish With Sour Cream and the Bowl Toppings
Stir the sour cream into the soup after removing the pot from the heat. The soup should look creamy and smooth, with potato pieces still visible throughout. Ladle it into bowls and finish with the reserved bacon, shredded sharp cheddar, and thinly sliced green onions. Add the toppings just before serving so the bacon stays crisp.
Three Easy Ways to Adapt This Baked Potato Soup
Make It Gluten-Free
Replace the all-purpose flour with a measure-for-measure gluten-free all-purpose flour blend. Whisk it into the melted butter and cook the roux for the same minute before gradually adding the liquids. The soup may be a little less silky, but the thickened base still gives the potatoes a creamy place to settle.
Use Yukon Gold Potatoes for Firmer Pieces
Swap in the same weight of Yukon Gold potatoes for the russets. They have a waxier texture and tend to hold their shape, so the finished soup will have firmer chunks and less of the fluffy baked-potato feel. Bake and cut them the same way before adding them to the thickened soup.
Make the Soup More Unified
For a thicker, less chunky bowl, mash a few of the potato pieces against the side of the pot after their gentle simmer. Leave the rest whole so the soup still has some texture. Stir in the sour cream once the pot is off the heat, as usual.
Storage and Reheating
- Refrigerator: Refrigerate covered within 2 hours and use within 3 to 4 days. The potatoes will absorb some broth as the soup sits, so it will be thicker when cold.
- Freezer: Freeze in airtight containers for up to 2 months for the best quality. The potatoes may soften and the dairy base may separate or turn grainy after thawing; stir gently as it warms.
- Reheating: Warm leftovers on the stovetop over low to medium-low heat, stirring often, until they reach 165°F. If the soup has thickened, loosen it with a little chicken broth, and don’t let it boil or the creamy base may separate.
