Ingredients for knorr steak and mushroom stroganoff
Pantry staples and one package of Knorr mix create restaurant-style stroganoff in minutes.
| Ingredient | Amount | Notes |
|---|---|---|
| Knorr Steak and Mushroom Sauce Mix 🍲 | 1 package | Standard 1.41 oz package |
| New York Strip Steak 🥩 | 1 lb | Cut into 0.5-inch strips |
| White Button Mushrooms 🍄 | 16 oz | Sliced into 0.25-inch pieces |
| Yellow Onion 🧅 | 1 whole | Diced into 0.25-inch pieces |
| Garlic Cloves 🧄 | 3 cloves | Minced into fine paste |
| Unsalted Butter 🧈 | 3 tbsp | Cold, cut into small cubes |
| Beef Broth 💧 | 1 cup | Low-sodium preferred |
| Sour Cream 🥛 | ½ cup | Full-fat for creaminess |
| Heavy Cream 🥛 | ¼ cup | Whole milk works in pinch |
| Dry White Wine 🍷 | ½ cup | Chardonnay or Sauvignon Blanc |
| Diamond Crystal Kosher Salt 🧂 | ½ tsp | Adjust to taste |
| Freshly Ground Black Pepper 🌶️ | ¼ tsp | Freshly cracked preferred |
| Egg Noodles 🍝 | 8 oz | Fresh or dried, cooked al dente |
The Knorr mix is the flavor foundation—grab the steak and mushroom variety from the pasta aisle at Walmart or Kroger. For the steak, New York strip holds up best to slicing, though sirloin works too. Pre-sliced steak strips from the meat counter save time. Mushrooms should be firm and dry—white buttons are perfect, but cremini adds earthier depth. The onion and garlic? Fresh is non-negotiable—no powdered shortcuts here. For the butter, unsalted gives you control over seasoning, but salted works if you reduce the added salt later.
No white wine? Substitute extra beef broth—just add 2 tbsp lemon juice for acidity. Sour cream too expensive? Greek yogurt at half the amount works surprisingly well. Heavy cream out of stock? Half-and-half plus 1 tbsp butter mimics the richness. The Knorr mix is non-negotiable though—no homemade substitutes capture that perfect umami-sour balance. For mushrooms, shrooms from the bulk bin at Whole Foods have the best texture, but store-bought works fine. Need to prep ahead? Sauté the mushrooms and onions first, then refrigerate for up to 2 days—just reheat gently before adding the steak.
This stroganoff reheats beautifully—simmer on low for 5-7 minutes to restore creaminess. Leftovers keep 3-4 days in the fridge, but the sauce thickens over time, so stir in a splash of broth when reheating. For meal prep, portion into containers with noodles separate—toss everything together when ready to eat. The dish freezes well for up to 2 months, though the texture changes slightly after thawing. Always serve with extra crusty bread—sourdough from the bakery section soaks up every last drop of that velvety sauce.

Step-by-step instructions for Knorr steak and mushroom stroganoff
Here's how to transform pantry staples into a restaurant-worthy stroganoff with minimal effort.
Sear the Steak and Sauté the Aromatics
Heat a large Dutch oven or heavy skillet over medium-high heat until hot. Add the 1 lb New York Strip Steak cut into ½-inch strips and sear for 2-3 minutes until the edges turn golden brown and the meat loses its raw appearance. Remove the steak and set aside on a plate.
In the same skillet, add 3 tbsp unsalted butter and let it melt completely. Add the 1 whole yellow onion diced into ¼-inch pieces and cook for 4-5 minutes until softened and translucent. Stir in the 16 oz white button mushrooms sliced into ¼-inch pieces and cook for another 5 minutes until they release their moisture and begin to brown.
Add the 3 cloves garlic minced into a fine paste and cook for 30 seconds until fragrant. Here's the thing—don't let the garlic burn, or you'll taste bitterness instead of sweet aroma. The mushrooms should be golden and slightly caramelized by now, creating the perfect flavor base for your stroganoff.
Build the Sauce with Knorr Mix and Wine
Pour in the ½ cup dry white wine and scrape up all the browned bits from the bottom of the pan with a wooden spoon. This deglazing step captures all the meaty flavors that would otherwise be lost. Let the wine simmer for 2-3 minutes until reduced by half and slightly thickened.
Add the 1 package Knorr Steak and Mushroom Sauce Mix and stir vigorously to dissolve completely. The mix will transform instantly into a rich, savory paste. Pour in the 1 cup beef broth and bring the mixture to a gentle simmer, stirring occasionally to prevent sticking. Let it cook for 5 minutes until slightly thickened and the flavors meld together.
Return the seared steak to the skillet and spoon the sauce over it. Let the mixture simmer together for 3-4 minutes until the steak is heated through and the sauce has thickened slightly. The steak should be tender but still hold its shape—overcooking will make it tough. Taste and adjust seasoning with ½ tsp Diamond Crystal kosher salt and ¼ tsp freshly ground black pepper if needed.
Create the Creamy Stroganoff Base
Reduce the heat to medium-low and stir in the ½ cup sour cream and ¼ cup heavy cream. Let the mixture simmer gently for 2-3 minutes, stirring constantly to prevent curdling. The cream will thicken the sauce and add that signature velvety texture stroganoff is known for.
Here's where it gets creamy: continue stirring for another 1-2 minutes until the sauce reaches your desired consistency. It should coat the back of a spoon but still be smooth and pourable. If it thickens too much, whisk in 1-2 tablespoons of hot beef broth to loosen it. The sauce should be rich, glossy, and perfectly balanced between the savory Knorr mix and the tangy cream.
Taste again and make any final adjustments to seasoning. The Knorr mix provides a solid flavor foundation, but the cream adds depth and richness that makes this stroganoff truly special. The sauce should be velvety, not clumpy, and have a perfect balance of saltiness from the mix and creaminess from the dairy.
Cook the Noodles and Combine
While the stroganoff sauce simmers, cook the 8 oz egg noodles according to package instructions until al dente. Drain the noodles but reserve ½ cup of pasta water—this starchy liquid is your secret weapon for adjusting the sauce consistency later. Toss the hot noodles with a little butter or olive oil to prevent sticking.
Return the stroganoff to a gentle simmer and add the cooked noodles. Gently fold everything together, letting the noodles absorb the creamy sauce. If the sauce seems too thick, add reserved pasta water 1 tablespoon at a time until it reaches a perfect coating consistency. The noodles should be fully coated in the rich stroganoff sauce without being soggy.
Let the combined dish simmer together for 1-2 minutes to heat through completely. The noodles will finish cooking in the residual heat of the sauce. Taste one final time and adjust seasoning if needed. The stroganoff should be creamy, flavorful, and perfectly balanced—ready to serve immediately. This one-pot method ensures maximum flavor with minimum cleanup, making it a true weeknight winner.
Pro Tips For Making Knorr Steak And Mushroom Stroganoff
- Sear the Steak First: DESCRIPTION: Take that New York strip out of the fridge while the pan heats—no waiting. A quick 2-3 minute sear in a screaming-hot skillet (cast iron if you’ve got it) locks in juices and builds flavor the sauce mix can’t fake. I used to skip this and wondered why my stroganoff tasted like a shortcut.
- Slice Mushrooms Thin: DESCRIPTION: Grab a sharp knife and cut those white buttons paper-thin—no thick, stubborn chunks. They’ll cook faster, release moisture evenly, and blend into the sauce instead of turning into mush. (Yes, I’ve made that mistake. Twice.)
- Bloom the Onion Slow: DESCRIPTION: Don’t rush the onion—let it sweat in the pan for 5 minutes on medium-low before adding garlic. This pulls out the natural sweetness and keeps it from burning into bitter ashes. I learned this the hard way after one overzealous batch turned my stroganoff into a sad, charred experiment.
- Stir the Sauce Mix Early: DESCRIPTION: Whisk the Knorr packet into the warm liquid before it fully boils, then let it simmer. This prevents clumping and gives you a smoother sauce. I used to dump it in raw, and half the time, I ended up fishing out lumps like a culinary archaeologist.
Troubleshooting great knorr steak and mushroom stroganoff
Sauce Too Thin?
If your stroganoff sauce feels watery, don’t panic—this happens when the Knorr mix absorbs too much liquid. Reduce heat to medium-low and let the sauce simmer uncovered for 5-7 minutes, stirring occasionally.
The starches in the mix will thicken naturally. For quicker results, whisk in 1 tbsp cornstarch mixed with 2 tbsp cold water and simmer for 1-2 minutes until glossy. 💡
Steak Overcooked?
Stroganoff steak should be tender but still hold its shape. If yours turns out tough, the issue is likely overcooking during the final simmer.
Next time, sear the steak just until it reaches 145°F internal temp (about 2-3 minutes for strips), then remove it from the pan while the sauce simmers. Return the steak to the skillet only for the final 2 minutes of cooking to reheat through. 🥩
Sauce Curdled Cream?
Adding cold cream to a hot pan is the #1 cause of curdling. Always reduce heat to medium-low before stirring in the sour cream and heavy cream. For extra insurance, whisk the cream first, then slowly drizzle it into the sauce while stirring constantly.
If curdling happens, whisk in 1 tbsp cold water and simmer gently for 1 minute to restore smoothness. 🥛
Mushrooms Too Watery?
Overcrowding the pan causes mushrooms to steam instead of brown, leading to a watery texture. Sauté them in 2 batches if needed, using a nonstick skillet for better release.
Pat mushrooms dry with a paper towel before cooking to remove excess moisture. For extra flavor, add ½ tsp smoked paprika with the mushrooms to enhance their earthiness. 🍄
Noodles Mushy?
Al dente noodles are key—overcooking turns them into a gluey mess. Cook them 1 minute less than package instructions, then finish in the stroganoff sauce. If they still seem undercooked, add ¼ cup hot pasta water to the sauce and simmer for 1 minute before combining.
For extra texture, toss with 1 tbsp butter before mixing. 🍝
Flavor Too Mild?
The Knorr mix provides base flavor, but you can amplify it with these pro tips: Add 1 tsp Worcestershire sauce with the wine for umami depth, or stir in ½ tsp Dijon mustard for tangy complexity.
For a smoky twist, sprinkle ¼ tsp chipotle powder into the sauce at the end. Always taste as you go—adjust salt and pepper gradually. 💫

Frequently asked questions
Can I make this stroganoff without wine?
Replace the ½ cup white wine with an equal amount of beef broth plus 1 tbsp lemon juice for acidity. The dish will still develop rich flavors—just add the lemon juice after deglazing. For extra depth, stir in ½ tsp vinegar instead of lemon juice.
What's the best way to reheat leftovers?
Reheat stroganoff gently on the stovetop over low heat for 5-7 minutes, stirring occasionally and adding 1-2 tbsp broth or water if the sauce thickens too much. Avoid microwaving—it can make the sauce grainy. For extra creaminess, stir in 1 tbsp sour cream at the end.
Can I use chicken instead of steak?
Yes! Swap the steak for 1 lb boneless chicken thighs or breasts, cut into strips. Cook them until they reach 165°F internal temp (about 5-6 minutes per side). Chicken absorbs flavors differently, so add ½ tsp smoked paprika to the sauce for extra depth. The dish becomes lighter but just as delicious.
Why did my sauce separate?
Sauce separation usually happens when cream is added too quickly to hot liquid. Always reduce heat to medium-low before stirring in creams, and whisk them first. If separation occurs, whisk in 1 tbsp cold water and simmer gently for 1 minute while stirring constantly. For prevention, temper the cream by mixing it with 2 tbsp hot broth before adding.
How do I make this stroganoff spicier?
Add heat by stirring in ½ tsp cayenne pepper or 1 tsp hot sauce with the Knorr mix. For smoky depth, sprinkle ¼ tsp chipotle powder into the sauce at the end. If you love fresh heat, top with diced jalapeños or red pepper flakes before serving. Always taste as you go!
