Easy Keto Beef Stroganoff Recipe for Beginners

I make this keto beef stroganoff at least twice a month when I want something rich and filling without the carbs. Standard stroganoff calls for egg noodles and flour-thickened sauce, which blows any low-carb budget. This keto version skips both and uses cream cheese to build a thick, velvety sauce that clings to every bite.

Why This Keto Beef Stroganoff Works

The sauce is the key. Cream cheese melts into the beef broth and creates a stable, glossy base that does not break or separate when you add the sour cream. It is richer than any flour-thickened version I have tried.

Flank steak gives you that tender, slightly chewy bite that holds up in the sauce. Slicing it thin against the grain is the one step that separates a great keto beef stroganoff from a tough one.

Cauliflower rice absorbs the sauce underneath and adds bulk without spiking carbs. Every bowl comes in under 8g net carbs per serving.

Ingredients

• 1.5 lbs (680g) flank steak, thinly sliced against the grain
• 2 tablespoons butter
• 1 small yellow onion, diced
• 3 cloves garlic, minced
• 8 oz (225g) cremini mushrooms, sliced
• 1 cup (240ml) beef broth
• 4 oz (115g) cream cheese, softened
• 1/2 cup (120ml) sour cream
• Salt and black pepper to taste

What You Need for Keto Beef Stroganoff

Flank steak — lean, full of flavor, and holds up well when seared at high heat. Sirloin or ribeye also work. Slice thin across the grain to keep it tender.

Butter — used for searing and building flavor in the sauce base. Ghee works as a 1:1 substitute for a slightly nuttier taste.

Cremini mushrooms — they release moisture as they cook, which concentrates into the sauce. Button mushrooms work fine, but creminis add more depth.

Beef broth — the liquid base of the sauce. Use a full-sodium broth for a more rounded flavor. Low-sodium works too — just add more salt at the end.

Cream cheese — this is what thickens the sauce without any starch. Let it soften at room temperature for 20 minutes so it melts smoothly.

Sour cream — added off the heat so it does not curdle. Full-fat gives the creamiest result and keeps the carbs lower than low-fat versions.

How to Make Keto Beef Stroganoff

1. Season sliced flank steak generously with salt and black pepper.
2. Heat 1 tablespoon butter in a large skillet over high heat. Sear beef in a single layer for 3 minutes per side until browned. Remove and set aside.
3. Reduce heat to medium. Add remaining butter, onion, and garlic. Cook for 3 minutes until softened.
4. Add mushrooms. Cook for 5 minutes until they release their moisture and turn golden.
5. Pour in beef broth. Scrape up any browned bits from the pan bottom.
6. Add cream cheese and stir until fully melted and smooth, about 3 minutes.
7. Return beef to the skillet. Remove from heat and stir in sour cream. Serve over cauliflower rice.

Keto Beef Stroganoff Variations

Ground Beef Stroganoff

Swap flank steak for 1.5 lbs (680g) of 80/20 ground beef. Brown it in the same skillet before adding the onions and garlic. The texture is looser but the flavor is just as rich, and the cook time drops to 25 minutes total.

Slow Cooker Keto Beef Stroganoff

Add seared beef, mushrooms, onion, garlic, and broth to a slow cooker on low for 6 hours. Stir in cream cheese 30 minutes before serving, then add sour cream at the table. The meat becomes very tender and pulls apart in the sauce.

Dairy-Free Keto Stroganoff

Replace cream cheese with 4 oz (115g) of full-fat coconut cream and sour cream with plain coconut yogurt. The sauce is slightly lighter in color and has a mild coconut undertone, but it stays thick and keto-friendly at under 6g net carbs.

Tips for the Best Keto Beef Stroganoff

• I always sear the beef in a single layer — crowding the pan steams instead of browns.
• Let the cream cheese soften before adding it to avoid lumps in the sauce.
• Add sour cream off the heat to prevent curdling.
• Scrape every browned bit off the pan when you pour in the broth — that is where the deep flavor lives.
• Taste the sauce before adding the beef back in and adjust salt then, not after.
• Serve immediately — the sauce thickens as it sits, especially with cauliflower rice underneath.

Make Ahead & Storage

This keto beef stroganoff keeps in the fridge for up to 4 days in an airtight container. I store the sauce and the cauliflower rice separately so the rice does not get waterlogged overnight.

To reheat, warm the beef and sauce over low heat with a splash of beef broth to loosen it. Add the sour cream again if the sauce looks separated. To freeze, cool completely and freeze the sauce alone for up to 3 months. Thaw overnight in the fridge and reheat on the stovetop.

Common Questions

Can I use Greek yogurt instead of sour cream in keto beef stroganoff?

Yes. Full-fat plain Greek yogurt swaps 1:1 for sour cream. Add it off the heat the same way. The flavor is slightly tangier and the texture is a little thinner, but it keeps the dish keto.

Is keto beef stroganoff gluten-free?

Yes, this recipe is naturally gluten-free. There is no flour, breadcrumbs, or thickener that contains gluten. Double-check your beef broth label if you are very sensitive.

What do I serve with keto beef stroganoff?

Cauliflower rice is the most common base. Hearts of palm pasta is a closer noodle substitute. Zucchini noodles also work well — just do not cook them in the sauce or they turn mushy.

How many net carbs are in keto beef stroganoff?

This recipe has about 7g net carbs per serving, not counting the cauliflower rice. A 1-cup (100g) serving of cauliflower rice adds about 3g net carbs, bringing the total to roughly 10g per bowl.
