This One-Pot Beef Stroganoff Soup turns the classic dish into a cozy, spoonable dinner with seared sirloin strips, browned mushrooms, tender egg noodles, and a tangy sour cream broth. Everything cooks in a single pot in about 40 minutes, and each bowl delivers roughly 25 grams of protein when the pot is split into 6 servings.
What Makes This One-Pot Beef Stroganoff Soup Great?
The secret is building flavor in layers in the same pot. The beef gets a fast, hot sear, the mushrooms get time to properly brown, and a little flour cooked into the vegetables gives the broth body before the sour cream goes in. The result tastes like stroganoff, just in soup form, and it doesn’t turn thin or watery.
Why You’ll Love It
- Weeknight friendly, the whole thing comes together in about 40 minutes with no separate pot for boiling noodles.
- Minimal cleanup, the searing, sautéing, simmering, and finishing all happen in one Dutch oven.
- Stretches 1 pound of beef further, the mushrooms and noodles make it filling enough to feed 6.
- Protein-packed without being heavy, lean sirloin does most of the work, so you get a hearty bowl without a pool of grease on top.
The Beef
Sirloin is the sweet spot here. It’s lean, affordable compared to tenderloin, and stays tender as long as it’s sliced thin and cooked quickly. The trick is a hard, fast sear, then pulling it out of the pot so it doesn’t turn chewy while the soup simmers.
Want even thinner slices? Pop the steak in the freezer for 20 to 30 minutes first. It firms up just enough to make slicing across the grain so much easier.
What You’ll Need for the Beef
- 1 lb beef sirloin, trimmed and sliced thinly across the grain into bite-sized strips, short fibers mean tender bites.
- 3/4 teaspoon kosher salt, seasons the meat before searing.
- 1/2 teaspoon black pepper, adds gentle heat that suits the creamy broth.
- 1 tablespoon olive oil, lets you sear hot without the butter burning.
The Mushroom and Onion Base
This is where most of the flavor comes from, honestly. Cremini mushrooms have a deeper, earthier taste than white button mushrooms, and when they’re given a few extra minutes to brown, they add that savory, almost meaty richness stroganoff is known for.
Yellow onion softens into sweetness, garlic and thyme bring aroma, and a spoonful of tomato paste cooked right into the pan adds color and depth.
What You’ll Need for the Mushroom and Onion Base
- 2 tablespoons unsalted butter, gives the vegetables a rich, rounded flavor.
- 10 oz cremini mushrooms, sliced, brown well and add earthy depth.
- 1 medium yellow onion, diced, turns soft and sweet as it cooks.
- 4 cloves garlic, minced, brings a warm, savory aroma.
- 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried), a classic match for beef and mushrooms.
- 1 tablespoon tomato paste, adds color and a subtle savory backbone.
- 3 tablespoons all-purpose flour, thickens the broth so it feels creamy rather than watery.
The Broth
The broth ties everything together. Using low-sodium beef broth keeps you in control of the salt, which matters because Worcestershire and the reduction during simmering both concentrate saltiness.
A little Dijon and smoked paprika aren’t traditional in every stroganoff, but they sharpen the flavor and keep the soup from tasting flat.
What You’ll Need for the Broth
- 6 cups low-sodium beef broth, the base of the soup and the cooking liquid for the noodles.
- 1 tablespoon Worcestershire sauce, adds tangy, savory depth.
- 1 teaspoon Dijon mustard, brightens the broth and balances the richness.
- 1/2 teaspoon smoked paprika, brings gentle warmth without spice.
The Noodles
Wide egg noodles are the classic choice, and they cook right in the broth. As they simmer, they release a bit of starch that helps thicken the soup even more. Not gonna lie, that’s half the appeal of the one-pot method.
What You’ll Need for the Noodles
- 6 oz wide egg noodles (about 3 cups), soft and tender, they soak up the savory broth.
The Creamy Finish
Sour cream is what makes this taste like stroganoff. It adds tang and creaminess, but it can split if it hits boiling liquid straight from the fridge. Tempering it with a little hot broth first solves that problem completely.
What You’ll Need for the Creamy Finish
- 2/3 cup full-fat sour cream, at room temperature if possible, gives the soup its signature tangy creaminess and is less likely to curdle than light versions.
- 2 tablespoons chopped fresh parsley, adds color and a fresh finish.
How to Make One-Pot Beef Stroganoff Soup
Sear the Beef
Pat the sirloin strips dry and toss them with the salt and pepper. Heat the olive oil in a large Dutch oven over medium-high heat until it shimmers.
Add the beef in a single layer, working in 2 batches so the pan doesn’t crowd, and sear for about 1 minute per side until browned on the outside but still pink inside.
Transfer to a plate and set aside.
Brown the Mushrooms
Lower the heat to medium and add the butter to the same pot. Once it melts, add the mushrooms and leave them alone for 2 to 3 minutes before stirring.
Cook for another 3 to 4 minutes until they’re golden and most of their liquid has cooked off. That patience is what gives the soup its deep flavor, trust me on this one.
Soften the Onion and Garlic
Add the onion and cook for about 4 minutes, stirring occasionally, until soft and translucent.
Stir in the garlic and thyme and cook for 30 seconds, just until fragrant. Add the tomato paste and stir for about 1 minute so it darkens slightly and coats the vegetables.
Cook in the Flour
Sprinkle the flour over the vegetables and stir constantly for 1 minute. It should coat everything and smell lightly toasty rather than raw.
This step is what gives the finished soup its silky body.
Build the Broth
Slowly pour in about 1 cup of the broth while stirring, scraping up all the browned bits from the bottom of the pot.
Once it’s smooth, add the remaining broth, Worcestershire, Dijon, and smoked paprika. Bring to a boil over medium-high heat; it will thicken slightly as it heats.
Simmer the Noodles
Stir in the egg noodles, then reduce the heat to a steady simmer. Cook for 7 to 9 minutes, stirring now and then so nothing sticks, until the noodles are tender.
The broth will have thickened noticeably by this point.
Temper the Sour Cream
Turn the heat down to low. Place the sour cream in a bowl and whisk in about 1 cup of the hot broth until smooth.
Stir this mixture back into the pot.
Keep the soup at a gentle heat from here on, because a hard boil can make the sour cream separate.
Finish with the Beef
Return the seared beef and any juices from the plate to the pot. Let it warm through on low for 2 to 3 minutes, just until no pink remains.
Thin strips this size cook through very quickly, well past the safe 145°F mark for beef. Taste, adjust the salt and pepper, and stir in most of the parsley before serving.
Variations and Customizations
This soup is pretty forgiving, so it’s easy to work with what you already have. Just keep the basic balance of seared protein, browned mushrooms, savory broth, and something tangy and creamy.
- Swap the beef, ground beef works well for a budget version (brown and drain it first), and boneless chicken thighs with chicken broth make a lighter take.
- Change the noodles, short pasta like rotini or small shells works, though cooking times may run a couple of minutes longer.
- Use Greek yogurt, plain full-fat Greek yogurt can replace the sour cream for extra tang and protein; temper it the same way.
- Add a splash of wine, deglaze with 1/4 cup dry red or white wine before adding the broth for a deeper, restaurant-style flavor.
- Make it vegetarian, skip the beef, double the mushrooms, use vegetable broth, and check that your Worcestershire is a vegetarian brand.
- Use leftover roast beef, slice it thinly and stir it in at the end just to warm through.
Toppings, Add-Ons, and Finishing Touches
The soup is rich and creamy, so the best toppings add freshness, tang, or a bit of crunch to balance it.
- Extra chopped parsley or fresh dill, for brightness.
- A spoonful of sour cream, for extra tang on top.
- Freshly cracked black pepper, for a little bite.
- Chopped chives or green onions, for a mild oniony freshness.
- A squeeze of lemon juice, to lift the richness right before eating.
- Crusty bread or buttered toast, for dunking (soooo good).
Storing, Reheating, and Meal Prep
Store leftovers in an airtight container in the fridge for up to 3 to 4 days. The noodles will keep soaking up broth, so expect a thicker, almost stew-like soup the next day. When reheating, warm it gently on the stove over low to medium-low heat and add a splash of broth or water to loosen it. Avoid boiling, which can make the sour cream separate and toughen the beef.
The finished soup doesn’t freeze well because the noodles turn mushy and the sour cream can go grainy. For make-ahead meals, cook the base through the broth stage and freeze it for up to 3 months. Thaw it in the fridge overnight, bring it back to a simmer, then cook the noodles, add the sour cream, and stir in freshly seared beef just before serving.

Instructions
Sear the Beef
-
Pat the sirloin strips dry with paper towels and season them with the salt and pepper. Heat the olive oil in a large Dutch oven over medium-high heat until it shimmers. Add half of the beef in a single layer and sear for about 1 minute per side, until browned on the outside but still pink in the middle. Transfer to a plate, repeat with the remaining beef, and set it all aside. The beef will finish cooking later, so it is fine that it is not cooked through yet.
Brown the Mushrooms
-
Reduce the heat to medium and add the butter to the same pot. Once it has melted, add the mushrooms and let them sit without stirring for 2 to 3 minutes so they can brown. Stir and cook for another 3 to 4 minutes, until they are golden and most of their liquid has cooked away. The mushrooms may release a lot of water at first, this is normal and it will evaporate.
Soften the Onion and Garlic
-
Add the onion and cook for about 4 minutes, stirring occasionally, until soft and translucent. Stir in the garlic and thyme and cook for 30 seconds, until fragrant. Add the tomato paste and stir for about 1 minute, until it darkens slightly and coats the vegetables.
Cook in the Flour
-
Sprinkle the flour over the vegetables and stir constantly for 1 minute. The flour should coat everything evenly and smell lightly toasted. This step helps the soup thicken into a smooth, silky broth.
Build the Broth
-
Slowly pour in about 1 cup of the broth while stirring, scraping up the browned bits from the bottom of the pot with a wooden spoon. Once the mixture looks smooth, add the remaining broth, Worcestershire sauce, Dijon mustard, and smoked paprika. Raise the heat to medium-high and bring the soup to a boil, about 5 minutes.
Simmer the Noodles
-
Stir in the egg noodles and reduce the heat to a steady simmer. Cook for 7 to 9 minutes, stirring occasionally so the noodles do not stick to the bottom, until they are tender. The broth will thicken noticeably as the noodles release some of their starch.
Temper the Sour Cream
-
Turn the heat down to low. Place the sour cream in a medium bowl and whisk in about 1 cup of the hot broth until smooth and creamy. Pour the mixture back into the pot and stir gently. Keep the soup at a low, gentle heat from this point so the sour cream stays smooth.
Finish and Serve
-
Return the seared beef and any juices from the plate to the pot. Warm it on low for 2 to 3 minutes, until no pink remains and the beef is tender. Taste and add a little more salt and pepper if needed. Stir in most of the parsley, ladle into bowls, and sprinkle the rest on top.
Note
For easier slicing, place the sirloin in the freezer for 20 to 30 minutes before cutting. It firms up and slices thinly with much less effort.
Slice the beef across the grain. This shortens the fibers and keeps each piece tender.
If the soup looks grainy or separated, the heat was likely too high after the sour cream went in. Lower the heat and stir gently. Bringing the sour cream to room temperature before tempering helps prevent this.
Store leftovers in an airtight container in the refrigerator for up to 3 to 4 days. The noodles will absorb more broth as the soup sits, so add a splash of broth or water when reheating.
Reheat gently on the stovetop over low to medium-low heat, stirring often. Avoid boiling, which can cause the sour cream to separate and the beef to toughen.
The finished soup does not freeze well because the noodles soften and the sour cream can turn grainy. To make ahead, freeze the broth base before adding the noodles and sour cream for up to 3 months, then finish with fresh noodles, sour cream, and freshly seared beef when ready to serve.
