Few dishes say comfort food quite like a heaping serving of beef stroganoff. It’s one of those dishes that instantly makes me feel relaxed, and I love how low-effort it is.
What I don’t love is the copious amount of carbs that come with it. So, I made some low-carb swaps to make it keto-friendly while keeping the signature flavors we all look forward to.
What is beef stroganoff?
Beef stroganoff is a Russian dish made up of tender beef in a creamy sauce. The most popular version has sautéed mushrooms and sour cream, and with a few low-carb substitutions, it can be made keto.

Why I love this recipe
- Ready in 20 minutes. This stroganoff is the perfect recipe for a quick dinner on busy weeknights.
- Just 3 grams of net carbs. For something so rich and hearty, no one would guess it’s low carb.
- Made in one skillet (or pot). Everything is made in the same skillet, from the vegetables to the beef!
- Or make it in the slow cooker! While I prefer the speed of the stovetop, I also tested it in my handy crockpot.
Ingredients needed
- Sirloin steak. My preferred cut of beef for this recipe since it’s naturally tender. Alternatively, you can use tenderloin, beef stew meat, or lean ground beef.
- Garlic and onion. Adds essential aromatics.
- Butter. I suggest using unsalted butter from a block, not a spread. Spreads have water added, which cuts down on their richness.
- Beef broth. For savory flavor. If you’re using low-sodium broth, add salt and black pepper to taste.
- Worcestershire sauce. The secret ingredient to give this dish an umami flavor.
- Mushrooms. I used sliced white button mushrooms.
- Almond flour. Thickens the sauce. Use blanched almond flour, not almond meal. I also tested the recipe with xanthan gum, and it worked fine.
- Sour cream. Adds creaminess and a subtle tang that balances out all the saltiness. Cream cheese is a good substitution.
- Keto noodles. To complement the dish! I used homemade keto pasta, but you can use store-bought pasta or cauliflower mashed potatoes.
How to make keto beef stroganoff
I’ve included step-by-step photos below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the recipe card at the bottom of this post.
Step 1- Cook the aromatics. In a non-stick skillet over medium heat, melt the butter. Add the garlic and onions, cook until soft, then remove them from the pan.
Step 2- Cook the steak. Slice the beef into 1-inch strips, cutting against the grain. Add the steak to the hot pan and cook for 4-5 minutes until no longer pink.
Step 3- Build the sauce. Add the broth and Worcestershire sauce and bring to a boil. Once boiling, reduce the heat to low and simmer for 15 minutes.
Step 4- Add mushrooms and simmer. Add the mushrooms, onion, and garlic. Whisk in the almond flour. Simmer for 5 minutes, then fold in the sour cream.
Step 5- Serve. Remove the pan from the heat and serve with low-carb pasta or mashed cauliflower.
Alternative cooking methods
While I prefer using the stovetop method for my stroganoff, I know many of you prefer to use a slow cooker, so I’ve included a tested crockpot option.
Slow cooker method: Melt butter in a skillet, then add the onion, garlic, and beef. Cook the beef until it is no longer pink. Add the cooked beef, vegetables, broth, Worcestershire sauce, and mushrooms to the slow cooker. Cook on low for 5-6 hours or high for 2-3 hours. Remove the lid, stir in the almond flour, and simmer for 30 minutes. Stir in the sour cream right before serving.
Arman’s recipe tips
- Try not to overcook the meat. It’ll continue to cook as the sauce simmers, so don’t be afraid to add the sauce ingredients when the meat is still slightly rare.
- Add a spoonful of Dijon mustard for a subtle tang.
- Garnish with fresh parsley for a pop of color.
- Serve the dish over keto egg noodles, zucchini noodles, cauliflower rice, or keto gnocchi.
Storage instructions
To store: Leftovers can be stored in the refrigerator in an airtight container for up to five days.

Reheating: Microwave in 30-second intervals or reheat on the stovetop until warm.
Frequently asked questions
The best way to thicken stroganoff without flour is to use xanthan gum or cornstarch. While cornstarch is not keto-friendly, the amount used is minimal and won’t affect the carbs too much.
Full-fat sour cream is keto-friendly, while low-fat and non-fat options contain more carbs. For any stroganoff recipe, you want to stick with full-fat sour cream because it melds into the casserole so much better than the other varieties.
