Red potato soup lands in that sweet spot between rustic and creamy: the potatoes break down just enough to thicken the broth, but the skins stay on for a hearty texture and those little red flecks that make each bowl look homemade in the best way. The bacon drippings, onion, garlic, and dill give it enough backbone that it tastes layered, not flat, and the sour cream keeps the finish tangy instead of heavy.
The trick here is using red potatoes, not russets. Red potatoes hold their shape better, which is what gives this soup its chunky, spoonable texture after you mash part of the pot. I also build the flavor in the bacon fat before the broth goes in, because that’s where the soup gets its savory base. The cheddar and sour cream go in off the boil so they melt smoothly instead of turning grainy.
Below, I’ve included the little details that matter most: how much to mash, when to stir in the dairy, and what to do if you want the soup a little thicker without losing that rustic feel.
The potatoes stayed chunky but the broth still turned silky once I mashed a few of them in the pot. The dill and sour cream gave it a fresh finish, and the bacon on top made it feel like a full meal.
Save this red potato soup for the nights when you want a creamy, bacon-rich bowl with real chunks of potato and fresh dill on top.
The Reason Red Potato Soup Stays Creamy Without Turning Gluey
Red potatoes are the difference between a soup that feels rustic and one that turns pasty. They have enough starch to thicken the broth once you mash a portion of them, but not so much that the whole pot turns into wallpaper paste. That’s why this soup gets body from the potatoes themselves instead of relying on a flour roux.
The other thing that matters is heat control after the dairy goes in. Heavy cream, sour cream, and cheddar all behave better when the soup is at a gentle simmer or lower. If you boil after adding them, the sour cream can split and the cheddar can go grainy. Pulling the pot off the heat for a minute before stirring in the dairy keeps everything smooth.
What Each Ingredient Is Actually Doing in This Bowl
- Red potatoes — These hold their shape better than russets, and the skins add the rustic texture you want in this soup. Scrub them well and keep the cubes fairly even so they cook at the same pace.
- Bacon — The bacon does double duty: it gives you the garnish, and the drippings become the base for the onion and garlic. If you skip it, use butter plus a little olive oil, but you’ll lose that smoky backbone.
- Chicken broth — This keeps the soup savory without making it heavy. A low-sodium broth is best because the cheddar and bacon already bring plenty of salt.
- Heavy cream and sour cream — Cream gives you body, while sour cream adds tang and keeps the soup from tasting one-note. Don’t swap in milk unless you’re fine with a thinner result.
- Cheddar — Sharp cheddar melts in with enough flavor to notice through the potatoes. Shred it yourself if you can; pre-shredded cheese melts less smoothly because of the anti-caking coating.
- Fresh dill — Dill is what keeps this soup from tasting like a standard potato soup. Add it at the end so the flavor stays bright instead of fading into the pot.
Building the Pot So the Soup Thickens the Right Way
Render the bacon first
Cook the bacon until it’s crisp and the fat in the pot has a clear, smoky smell. You want the bacon browned, not burned, because those drippings are what carry the onion and garlic. If the pot looks dry, add a small spoonful of butter before the onion goes in; you need enough fat to soften the vegetables without scorching them.
Soften the onion before the broth goes in
Let the onion cook until it turns translucent and starts to pick up a little color at the edges. Then add the garlic for just a minute. Garlic burns fast in hot fat, and once it turns bitter, the whole soup tastes sharp in the wrong way.
Simmer the potatoes until they collapse at the edge
Add the broth and cubed potatoes, then simmer until the pieces are very tender and a fork slides through without resistance. The potatoes should be soft enough that the edges start to break when stirred. If they’re still firm in the center, don’t rush the next step; undercooked potatoes won’t mash smoothly and the soup will stay thin.
Mash only part of the pot
Use a potato masher right in the pot and mash some of the potatoes, not all of them. You want a mix of creamy broth and visible chunks, with the skins still showing. This is the move that gives the soup its texture, and if you overdo it, you lose the rustic feel and end up with a dense mash.
Finish with dairy off the heat
Stir in the cream, sour cream, and cheddar after the pot is no longer boiling. The soup should be hot enough to melt the cheese, but not so hot that it seizes or splits. Stir until the cheddar disappears and the broth looks glossy, then season and add the dill right at the end.
Three Ways to Adjust This Soup Without Losing What Makes It Good
Dairy-Free Version
Use olive oil or dairy-free butter in place of the bacon drippings if needed, and swap the cream and sour cream for full-fat coconut cream and a plain unsweetened dairy-free yogurt. The flavor changes a bit, but the soup still gets that creamy finish and the potatoes still do the thickening. Skip the cheddar or use a meltable dairy-free cheese if you already know you like the flavor.
Vegetarian Version
Leave out the bacon and start the onion in butter with a little olive oil so it still gets good color. Use vegetable broth instead of chicken broth, then finish with the same cream, sour cream, cheddar, and dill. You’ll lose the smoky depth, so a pinch of smoked paprika helps bring some of that savory note back.
Thicker, More Chowder-Like Soup
Mash an extra cup or so of potatoes and let the soup rest for five minutes before serving. The starch settles and thickens the pot as it sits. Don’t add flour unless you have to; the potatoes already do the work, and flour can mute the clean potato flavor.
Storage and Reheating
- Refrigerator: Store for up to 4 days. The soup thickens as it chills, so it may look looser when reheated.
- Freezer: It freezes, but the dairy can separate a little on thawing. For the best texture, freeze before adding the cream, sour cream, and cheddar, then stir those in after reheating.
- Reheating: Warm it gently over low heat and stir often. Don’t boil it, or the dairy can break and the potatoes can start to disintegrate.

Method
- Cook the bacon in a large Dutch oven over medium heat until cooked and the fat renders, then remove and set aside, leaving the drippings. Keep the bacon nearby so you can add it back at serving.
- Sauté the diced onion in the drippings for 4 minutes, stirring until softened and lightly translucent. Add the minced garlic and cook 1 minute to bloom the aroma.
- Add the chicken broth and cubed red potatoes (with skins on) to the pot, then bring to a gentle simmer. Simmer for 18-20 minutes, until the potatoes are very tender and mash easily.
- Mash some of the potatoes in the pot to thicken the soup while leaving a rustic chunkiness from the red skins. Stir so the texture looks evenly distributed.
- Stir in the heavy cream and sour cream until the soup looks creamy and smooth. Add the shredded cheddar and stir until fully melted.
- Season with salt and black pepper, then stir in the chopped fresh dill. Taste and adjust seasoning if needed.
- Ladle the soup into bowls and top with the reserved bacon, green onions, and extra sour cream. Serve hot so the cheddar stays silky.
