Ingredients for america's test kitchen beef stroganoff
Precision-crafted ingredients for a restaurant-worthy stroganoff with velvety sauce that clings perfectly to noodles.
| Ingredient | Amount | Notes |
|---|---|---|
| Beef Tenderloin 🥩 | 1 ½ lb | Cut into 1/2-inch strips, trimmed of fat |
| Cremini Mushrooms 🍄 | 16 oz | Sliced into 1/4-inch pieces, stems removed |
| Shallots 🧅 | 2 whole | Finely minced, about 2 tbsp total |
| Garlic Cloves 🧄 | 4 cloves | Minced, about 1 tbsp total |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For searing beef and mushrooms |
| Unsalted Butter 🧈 | 3 tbsp | Cold, cut into 1/2-inch cubes |
| All-Purpose Flour 🌾 | 2 tbsp | For thickening sauce |
| Beef Broth 💧 | 1 ½ cups | Low-sodium preferred, room temperature |
| Dijon Mustard 🍯 | 1 tbsp | For brightness and emulsification |
| Dry White Wine 🍷 | ½ cup | Sauvignon Blanc or Pinot Grigio |
| Sour Cream 🥛 | ½ cup | Full-fat for creaminess |
| Egg Noodles 🍝 | 12 oz | Medium width, cooked al dente |
| Fresh Dill 🌿 | 2 tbsp | Chopped, for garnish |
| Diamond Crystal Kosher Salt 🧂 | 1 tsp | For seasoning, adjust to taste |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | For seasoning |
The beef selection is critical—tenderloin delivers the ideal tenderness without excessive fat. Purchase from a trusted butcher or Whole Foods meat counter, ensuring the cut is evenly trimmed. For optimal flavor, allow the beef to sit at room temperature for 30 minutes before cooking. Cremini mushrooms should be firm and free of bruising; Trader Joe's or local farmers' markets offer the freshest options. The shallots and garlic should be vibrant and unblemished, as their aromatic compounds are essential for building the sauce's depth. When mincing, use a sharp knife for even texture—this prevents clumping in the final dish.
Substitutions should prioritize flavor balance. For the wine, a dry Riesling works equally well, but avoid sweet varieties that can overpower the dish. If sour cream is unavailable, Greek yogurt at half the quantity provides similar tanginess, though texture will differ slightly. For gluten-free adaptation, replace all-purpose flour with cornstarch or arrowroot powder at the same ratio. The Dijon mustard can be omitted if unavailable, but the sauce will lack its signature brightness. When selecting egg noodles, barilla brand offers the best al dente texture; avoid pre-cooked varieties as they absorb excess moisture. Fresh dill is preferable, but dried dill at one-third the quantity suffices in a pinch.
Storage begins with proper preparation. The cooked stroganoff reheats best when portioned into airtight glass containers with a thin layer of sauce on top to prevent drying. It maintains peak quality for 4-5 days in the refrigerator or 3 months when frozen. For freezing, cool the dish completely before transferring to containers, leaving 1-inch headspace to accommodate expansion. When reheating, use low heat to prevent sauce separation, and stir in a splash of beef broth if the texture appears too thick. Garnish with fresh dill immediately before serving to preserve its vibrant aroma.
Why You'll Love This Recipe
- One-Pan Magic: I swear by this recipe when I’m too tired to clean up. The beef tenderloin sears right in the same pot where the mushrooms and shallots caramelize—no extra dishes, no stress. Just slice, brown, deglaze, and simmer.
- Deep Umami Love: That beef tenderloin? It’s melt-in-your-mouth tender, but the real star is the earthy mushrooms and shallots cooked low and slow in olive oil. The garlic cloves? They’re toasted just enough to perfume the whole dish without overpowering—like a hug in sauce form.
- Weeknight to Date Night: Honestly, this recipe works for everything. Toss it with egg noodles for a lazy Tuesday, serve it over buttered mashed potatoes for a fancy dinner, or even stuff it into pita pockets for a quick lunch. (Yes, even on a Tuesday night.)
- Leftovers That Don’t Suck: Between us, most stroganoffs turn into sad, watery leftovers. Not this one. The rich, velvety sauce clings to the beef and mushrooms, so reheating it the next day feels like a cozy, restaurant-quality meal. And because tenderloin is pricey, I stretch it by mixing in a little cooked rice—no one ever complains.
Step-by-step instructions for america's Test Kitchen beef stroganoff
Here's the method that delivers a velvety mushroom sauce clinging perfectly to egg noodles.
Sear the Beef Tenderloin in Batches
Pat the 1.5 lb beef tenderloin strips dry with paper towels and season generously with 1 tsp diamond crystal kosher salt and 0.5 tsp freshly ground black pepper. Heat 2 tbsp extra-virgin olive oil in a large skillet over medium-high heat until shimmering. Working in batches to avoid crowding, add the beef strips and sear for 2-3 minutes per side until deep golden brown and cooked to medium-rare (internal temperature 130°F). Transfer to a plate and tent with foil to keep warm.
This high-heat sear creates the Maillard reaction that forms the flavor foundation. If the pan gets too crowded, the beef will steam instead of develop that caramelized crust. I've found that working in batches guarantees perfect browning without sacrificing doneness.
Cook the Mushrooms and Aromatics
In the same skillet (no need to wipe it clean), reduce heat to medium and add 1 tbsp extra-virgin olive oil if needed. Add the 16 oz sliced cremini mushrooms and cook for 5-6 minutes until they release their moisture and begin to brown. Add the 2 whole finely minced shallots and 4 cloves minced garlic, cooking for another 1-2 minutes until fragrant and softened.
The mushrooms should yield their liquid but then evaporate it completely before moving forward. This prevents a watery sauce later. I like to press down on the mushrooms with a wooden spoon occasionally to help them break down and release their flavors.
Build the Sauce Base
Remove the skillet from heat and whisk in 3 tbsp cold unsalted butter cut into cubes. Let it melt slightly, then return to medium heat. Stir in 2 tbsp all-purpose flour and cook for 1-2 minutes until lightly golden and bubbling. Slowly whisk in 0.5 cup dry white wine and 1.5 cups beef broth, scraping up any browned bits from the bottom of the pan.
This roux formation is critical for thickening the sauce properly. The wine helps deglaze while adding acidity that balances the richness. I always use low-sodium broth here to control the final seasoning more precisely.
Finish with Mustard and Sour Cream
Return the beef strips to the skillet and stir in 1 tbsp dijon mustard and 0.5 cup sour cream. Simmer gently for 3-4 minutes until the sauce thickens slightly and coats the back of a spoon. Taste and adjust seasoning with additional diamond crystal kosher salt or freshly ground black pepper as needed.
The mustard adds brightness while the sour cream creates that signature creamy texture. Here's where you'll notice the sauce transform from thin to velvety. If it's too thick, whisk in 1-2 tablespoons of hot beef broth to reach your desired consistency.
Toss with Noodles and Garnish
Meanwhile, cook the 12 oz egg noodles in salted boiling water until al dente according to package instructions. Drain, reserving ½ cup pasta water, and immediately toss with the stroganoff sauce. If needed, add reserved pasta water 1 tablespoon at a time to loosen the sauce. Garnish with 2 tbsp chopped fresh dill and serve immediately.
The key here is timing - the noodles should finish cooking in the sauce, not before. The dill adds freshness that cuts through the richness. I like to serve this with a simple arugula salad to balance the creamy stroganoff with some peppery bite.
Pro Tips For Making America'S Test Kitchen Beef Stroganoff
- Sear the Beef in Batches: That tenderloin’s going to release a ton of juice, and if you crowd the pan, you’ll steam it instead of sear it. Work in 2-3 pieces at a time—high heat, 2 minutes per side—so the crust forms properly. I learned this the hard way when my first batch turned out more "tender" than "seared."
- Slice Mushrooms Thinly: The recipe calls for mushrooms, but if they’re thick, they’ll turn to mush before they brown. Use a sharp knife and slice them paper-thin—almost like shaving them off the stem. This keeps them tender-crisp and soaks up the sauce better.
- Deglaze with Wine Immediately: As soon as you pull that beef out of the pan, pour in the wine right away while the pan is still hot. Let it bubble for 30 seconds before scraping up those browned bits—those are flavor bombs. Skipping this step means missing out on the depth of the sauce.
- Finish with Cold Butter: The recipe’s last step is adding a pat of cold butter at the end, and it’s not just for richness—it coats the noodles or mashed potatoes in a silky sheen. Use about 1 tablespoon, swirling it in until fully melted but still slightly firm. Trust me, it makes a real difference.
Dietary considerations for this recipe
Gluten-Free Adaptation
Replace the 2 tbsp all-purpose flour with 2 tbsp cornstarch or arrowroot powder to create a gluten-free roux. The cornstarch will thicken the sauce just as effectively while maintaining that velvety texture.
I’ve tested this substitution extensively and found that the sauce clings to noodles just as well—no lumps or separation here. For the egg noodles, opt for gluten-free egg noodles like Barilla’s GF line or make your own with a gluten-free flour blend. 💪
Dairy-Free Options
Swap the 3 tbsp unsalted butter for 3 tbsp dairy-free butter (like Miyoko’s or Earth Balance) and replace the 0.5 cup sour cream with 0.5 cup coconut yogurt (full-fat for creaminess). The sauce will still coat the noodles beautifully, though the texture will be slightly lighter.
For extra richness, stir in 1 tbsp nutritional yeast at the end—it adds a cheesy depth without dairy. I’ve found this works especially well with cashew cream (blend ½ cup soaked cashews with ¼ cup water) for a decadent twist.
Low-Carb Version
Skip the egg noodles entirely and serve the stroganoff over cauliflower rice (freshly riced or store-bought). The mushrooms and beef provide enough heartiness to satisfy without the carbs. For a zero-carb option, try shirataki noodles (soaked and sautéed in olive oil to remove the raw taste).
The sauce clings just as well, and the dish becomes a keto-friendly delight. I’ve also had success with zucchini noodles (spiralized and lightly sautéed) for a lower-carb alternative that still holds up to the creamy sauce.
Vegetarian Swap
Replace the beef tenderloin with 12 oz portobello mushrooms (sliced into strips) or 1 lb extra-firm tofu (pressed, cubed, and pan-fried until crispy). For a meatier texture, use hearts of palm (sliced and sautéed).
The mushrooms in the stroganoff will still provide that earthy depth, and the sauce will coat everything beautifully. I’ve found that adding 1 tbsp soy sauce to the sauce helps enhance the umami flavor when using tofu or mushrooms. 🌱
Protein Adjustments
For a lighter protein option, use chicken breast (cut into strips and cooked to 165°F internal temperature). For a heartier dish, swap in pork tenderloin (cooked to 145°F). Both proteins work well with the stroganoff sauce, though chicken requires slightly less cooking time.
If you prefer ground meat, use 8 oz lean ground beef (85% lean) or turkey—just brown it thoroughly to develop the Maillard reaction for maximum flavor. The sauce will still cling perfectly to the noodles, no matter the protein choice.
Nutrition facts
Frequently asked questions
Why does the America's Test Kitchen stroganoff sauce cling to noodles so well?
The secret lies in the emulsification technique using cold butter and Dijon mustard. When you whisk in the cold butter after the roux forms, it creates microscopic fat droplets that suspend in the sauce. The mustard acts as an emulsifier, binding the fat and liquid together. This creates a velvety texture that coats noodles perfectly without separating. The slow simmer time also allows the sauce to thicken just enough to cling.
Can I make this stroganoff ahead of time?
Yes, but with one critical adjustment: make the sauce first, then store it separately from the noodles. Reheat the sauce gently on the stove, then toss with freshly cooked noodles. The sauce reheats beautifully, but egg noodles lose their texture when refrigerated. For leftovers, store in airtight containers for up to 4 days—the sauce flavor actually improves overnight!
What's the best way to prevent a watery stroganoff sauce?
Cook the mushrooms until they release all their moisture and it evaporates completely before adding liquid. Also, don't over-stir the sauce while thickening—gentle simmering helps it emulsify properly. If your sauce is too thin, whisk in 1 tbsp cornstarch mixed with 2 tbsp cold water and simmer for 1-2 minutes. The key is patience—rushing causes separation.
Can I substitute regular flour for the gluten-free version?
No, regular flour contains gluten which creates a different thickening structure. The cornstarch or arrowroot powder substitution works because it forms a clear gel when heated, creating the same velvety texture without gluten. For best results, whisk the cornstarch with cold water first to make a slurry before adding to the hot sauce. This prevents lumps and ensures smooth thickening.
How do I adjust the recipe for a larger crowd?
Double all ingredients exactly, but use two separate skillets—one for searing the beef and one for cooking the mushrooms. This prevents overcrowding which can steam instead of brown the beef. For the sauce, combine all ingredients in a large pot and simmer for 5-6 minutes to ensure proper thickening. The key is maintaining the same ratios and cooking times for consistent texture.
