Step-by-Step Instructions

Step 1: Prepare the Beef

Slice the steak thinly against the grain. Pat dry with paper towels and season generously with salt and pepper.

Heat 1 tablespoon of oil in a large skillet over medium-high heat. Add the beef in a single layer (work in batches if needed). Sear for 1–2 minutes per side until browned but still tender inside.

Remove the beef from the skillet and set aside. Do not overcook—it will finish cooking later in the sauce.

Step 2: Cook the Vegetables

Reduce heat to medium. Add butter to the same skillet.

Add onions and sauté for 3–4 minutes until soft and translucent.

Stir in mushrooms and cook for 5–7 minutes until they release their moisture and begin to brown.

Add minced garlic and cook for 30 seconds until fragrant.

Step 3: Build the Sauce

Pour in the beef broth, scraping up any browned bits from the bottom of the pan (this adds flavor).

Stir in Dijon mustard, Worcestershire sauce, paprika, and thyme.

Let the mixture simmer for 3–5 minutes to reduce slightly.

Lower the heat and stir in cream cheese until fully melted and smooth.

Add sour cream and mix until creamy. Do not boil once sour cream is added—keep heat low to prevent curdling.

If you’d like a thicker sauce, sprinkle xanthan gum evenly while whisking continuously. Simmer 1–2 minutes until thickened.

Step 4: Finish the Dish

Return the beef (and its juices) to the skillet. Stir gently to coat in sauce.

Simmer for 3–5 minutes until beef is cooked to your preferred doneness and sauce is thick and creamy.

Taste and adjust salt and pepper if needed.

How to Serve (Low-Carb Options)

Instead of egg noodles, try:

🥦 Creamy cauliflower mash (most comforting option)
🥒 Zucchini noodles for a lighter feel
🌾 Cauliflower rice for meal prep
🥬 Sautéed cabbage for a budget-friendly base

Top with fresh parsley and extra cracked pepper before serving.

Storage & Meal Prep

Refrigerator: Store in an airtight container for up to 4 days.
Freezer: Can be frozen for up to 2 months (texture may change slightly due to sour cream).
Reheating: Warm gently on the stovetop over low heat. Add a splash of broth if needed.

Tips for Perfect Keto Stroganoff

Slice beef thinly for maximum tenderness.
Use full-fat dairy for best keto macros and creaminess.
Don’t boil after adding sour cream.
Add xanthan gum slowly—too much can make the sauce gummy.
For extra richness, stir in a tablespoon of heavy cream at the end.

Variations

Dairy-Free: Use coconut cream instead of sour cream and dairy-free cream cheese.
Extra Creamy: Add ¼ cup heavy cream.
Spicy Kick: Add a pinch of red pepper flakes.
Slow Cooker Version: Brown beef first, then cook everything except sour cream on low for 4–6 hours. Stir in sour cream at the end.

What cut of beef works best?
Sirloin, ribeye, or tenderloin are ideal. Avoid tough stew meat unless slow cooking.

Can I make this ahead?
Yes! The flavor actually improves the next day.
