Keto Beef Stroganoff

This keto beef stroganoff is rich, creamy, and comes together in about 30 minutes. It’s one of those comfort food classics that works perfectly on a low carb diet.

Traditional beef stroganoff usually calls for egg noodles or pasta, which are loaded with carbs. This version skips all of that and still tastes just as good, if not better.

The sauce is made with a combination of heavy cream and sour cream, so it’s incredibly smooth and flavorful. Pair it with tender seared sirloin and sautéed mushrooms and you’ve got a seriously satisfying dinner.

Serve it over cauliflower rice or zucchini noodles to keep it keto friendly, and you’re all set.

If you’ve been missing stroganoff since going low carb, this one is going to make you very happy.

Recipe Ingredients

• 1.5 lb Sirloin Steak, thinly sliced
• 1 tsp Salt
• 1/2 tsp Black Pepper
• 2 tbsp Olive Oil
• 4 tbsp Butter
• 1 small Onion, diced
• 8 oz Mushrooms, sliced
• 3 cloves Garlic, minced
• 1 cup Beef Broth
• 1 tbsp Dijon Mustard
• 1 tbsp Worcestershire Sauce
• 1 cup Heavy Cream
• 1/2 cup Sour Cream
• 2 tbsp Chopped Fresh Parsley

How To Make

Step 1

Season the sliced sirloin with salt and pepper. Heat the olive oil in a large skillet over high heat and sear the beef for 1-2 minutes until just browned. Transfer to a plate.

Step 2

Reduce heat to medium and melt the butter in the same skillet. Add the onion and mushrooms, sautéing for 6-7 minutes until softened and golden.

Step 3

Stir in the garlic and cook for 30 seconds until fragrant.

Step 4

Pour in the beef broth, Dijon, and Worcestershire, scraping up the browned bits. Simmer for 3 minutes to reduce.

Step 5

Lower the heat and stir in the heavy cream. Simmer gently for 4-5 minutes until thickened.

Step 6

Remove from heat and stir in the sour cream until smooth. Return the beef and any juices to the skillet and warm through.

Step 7

Sprinkle with fresh parsley and serve over cauliflower rice or zucchini noodles.

Tips

Slice the Steak While It’s Cold

Put the sirloin in the freezer for about 20-30 minutes before slicing it. When the meat is partially frozen, it firms up just enough that you can cut really thin, even slices without the steak sliding around on you.

Thin slices are important here because they cook fast and stay tender. If your slices are too thick, they’ll need more time in the pan and you’ll end up with chewy, overcooked beef.

Sear the Beef in Batches

Don’t dump all 1.5 pounds of steak into the skillet at once. If you crowd the pan, the beef will steam instead of sear and you won’t get that nice brown crust on the outside.

I recommend doing two batches. Spread the slices out in a single layer with space between them, let them sit untouched for about a minute, then flip and give them another 30 seconds or so.

You want the beef slightly underdone at this stage because it goes back into the sauce later to warm through. If you fully cook it now, it’ll be tough by the time you serve it.

Get Good Color on the Mushrooms

When you add the mushrooms, resist the urge to stir them constantly. Let them sit in the pan for a couple of minutes without touching them so they can brown properly. Mushrooms release a lot of water, and if you keep moving them around, they’ll just steam and turn soggy.

Once they start getting golden on the bottom, give them a stir and let them sit again. You’ll know they’re ready when they’ve shrunk down, the moisture has cooked off, and they have a nice caramelized look. This adds a ton of flavor to the sauce.

Frequently Asked Questions

Can I use a different cut of beef instead of sirloin?

Yes, you can use other tender cuts like ribeye or flank steak. Just make sure to slice the meat thinly against the grain so it stays tender in the quick sear.

Avoid tougher cuts like chuck or stew meat here since this recipe cooks the beef very fast. Those cuts need long, slow cooking to become tender and won’t work well with the short searing time in this stroganoff.
