Kluski beef stroganoff is a hearty, comforting dish that combines tender egg noodles (kluski) with a rich, creamy mushroom-beef sauce. It’s a beloved Polish-American adaptation of the classic Russian stroganoff, and it works beautifully as a weeknight dinner because it comes together in one pot with minimal fuss. The kluski noodles are sturdy enough to hold up to the thick, savory sauce, making every bite satisfying and flavorful.
Ingredients
- 1 lb (450 g) beef sirloin or tenderloin, thinly sliced into strips
- 2 tbsp (30 ml) olive oil, divided
- 1 medium onion, finely chopped
- 8 oz (225 g) cremini or button mushrooms, sliced
- 2 cloves garlic, minced
- 3 tbsp (45 g) all-purpose flour
- 2 cups (480 ml) beef broth, low-sodium
- 1 tbsp (15 ml) Worcestershire sauce
- 1 tsp (5 g) Dijon mustard
- 1/2 cup (120 ml) sour cream, at room temperature
- 12 oz (340 g) kluski egg noodles (or wide egg noodles)
- Salt and freshly ground black pepper, to taste
- 2 tbsp (8 g) fresh parsley, chopped (for garnish)
Instructions
- Season the beef strips generously with salt and pepper. Heat 1 tablespoon of olive oil in a large Dutch oven or heavy pot over medium-high heat. Add the beef in a single layer (work in batches if needed) and sear for 1–2 minutes per side until browned but not cooked through. Transfer the beef to a plate and set aside.
- Reduce heat to medium and add the remaining tablespoon of olive oil. Add the onion and cook for 3–4 minutes until softened. Add the mushrooms and cook for 5–6 minutes, stirring occasionally, until they release their liquid and start to brown. Add the garlic and cook for 30 seconds until fragrant.
- Sprinkle the flour over the vegetables and stir well to coat. Cook for 1 minute to remove the raw flour taste.
- Slowly pour in the beef broth while stirring constantly to avoid lumps. Add the Worcestershire sauce and Dijon mustard. Bring the mixture to a simmer and let it thicken for 2–3 minutes.
- Return the beef and any accumulated juices to the pot. Reduce heat to low, cover, and simmer gently for 10–15 minutes until the beef is tender and the sauce has thickened. The beef should reach a safe minimum internal temperature of 145°F (63°C) as measured with a food thermometer, followed by a 3-minute rest.
- While the sauce simmers, cook the kluski noodles according to package instructions in a separate pot of salted boiling water until al dente. Drain well.
- Once the beef is done, remove the pot from the heat. Stir in the sour cream until fully incorporated and the sauce is smooth. Taste and adjust seasoning with salt and pepper.
- Add the cooked noodles to the pot and toss gently to coat with the sauce. Let it sit for 2–3 minutes so the noodles absorb some of the sauce.
- Garnish with fresh parsley and serve hot.
Tips
- Substitutions: If you can’t find kluski noodles, use wide egg noodles or even pappardelle. For a lighter version, use Greek yogurt instead of sour cream, but add it off the heat to prevent curdling.
- Don’t overcook the beef: Searing the beef quickly and then simmering it gently keeps it tender. Overcooking can make it tough and chewy.
- Room-temperature sour cream: Always add sour cream at room temperature and off the heat to avoid curdling. If it’s cold, it can seize and create a grainy sauce.
- Make it ahead: You can prepare the sauce (without the noodles) up to 2 days ahead and refrigerate. When ready to serve, reheat the sauce gently and stir in freshly cooked noodles.
Serving Suggestions
Kluski beef stroganoff is a complete meal on its own, but it pairs wonderfully with a simple green salad tossed in a light vinaigrette or steamed green beans. For a touch of brightness, serve with a dollop of extra sour cream and a sprinkle of fresh dill. Crusty bread or garlic toast is great for soaking up any extra sauce.
Variations
- Chicken Stroganoff: Swap the beef for chicken breast or thighs. Cook the chicken until it reaches 165°F (74°C) internally, then follow the same steps.
- Mushroom Stroganoff: Omit the beef entirely and double the mushrooms for a vegetarian version. Use vegetable broth instead of beef broth.
- Spicy Kick: Add a teaspoon of smoked paprika or a pinch of cayenne pepper along with the garlic for a smoky heat.
- Herb Infusion: Stir in a teaspoon of fresh thyme or rosemary with the onions for an earthy flavor.
Storage and Reheating
Store leftovers in an airtight container in the refrigerator for up to 3–4 days. The noodles will absorb some sauce, so you may want to add a splash of beef broth or water when reheating to loosen it up. Reheat gently on the stovetop over medium-low heat, stirring occasionally, until heated through to 165°F (74°C). You can also microwave individual portions in 30-second bursts, stirring in between. Avoid boiling, as that can make the beef tough and the sauce curdle. Freezing is not recommended because the sour cream sauce can separate and become watery upon thawing.
Frequently Asked Questions
Can I use a different cut of beef? Yes, you can use beef chuck or round steak, but they are tougher and will require a longer simmering time (about 45–60 minutes) to become tender. Sirloin or tenderloin are best for quick cooking.
What if I don’t have kluski noodles? Kluski noodles are a type of Polish egg noodle that are slightly thicker and more substantial than regular egg noodles. If unavailable, use wide egg noodles, which have a similar texture and absorb the sauce well.
Can I make this gluten-free? Yes, use gluten-free egg noodles (or another gluten-free pasta) and substitute the all-purpose flour with a gluten-free flour blend or cornstarch. Mix the cornstarch with a little cold water to make a slurry before adding to the sauce.
Why did my sauce curdle? Curdling usually happens when the sour cream is added to a hot liquid too quickly or at too high a temperature. Always remove the pot from the heat, let it cool for a minute, and stir in the sour cream gradually. Using room-temperature sour cream also helps.
Can I add vegetables? Absolutely. Peas, carrots, or bell peppers are great additions. Add them along with the mushrooms and adjust the cooking time accordingly.
Is this dish spicy? No, it’s not spicy. It’s savory and creamy, with a slight tang from the sour cream and Dijon mustard. If you like heat, add a pinch of red pepper flakes or a dash of hot sauce.
