This keto ground beef stroganoff skillet is creamy, savory, and packed with mushrooms. It has the cozy flavor of classic beef stroganoff, but it is made with ground beef in one pan and skips the noodles to stay low carb.

It takes about 25 minutes from start to finish and uses just eight simple ingredients. That makes it a great fallback dinner for busy nights when you have a pound of ground beef in the fridge and not much of a plan. It serves 4.

Why This Keto Stroganoff Works

Traditional stroganoff uses strips of steak and a flour-thickened sauce served over egg noodles. This version keeps the parts that matter most for flavor: browned beef, mushrooms, onion, and tangy sour cream. Ground beef cooks fast and is easy on the budget.

The sauce gets its body from sour cream instead of flour. A short simmer with beef broth pulls up all the browned bits from the pan, and the sour cream turns it smooth and creamy once the heat is off. The result is rich and filling with very few carbs.

Ingredients and Easy Swaps

Ground beef (1 pound): 80/20 or 85/15 gives the most flavor for keto. Ground turkey works too, but add a pat of butter for richness.
Onion (1/2, diced): Yellow or white onion. Use a bit less if you are watching carbs closely.
Mushrooms (1 cup, sliced): Cremini have more flavor than white button mushrooms. Feel free to double them.
Beef broth (1/2 cup): Bone broth adds extra depth.
Sour cream (1/2 cup): Full-fat is best for keto and is less likely to curdle. Cream cheese makes an even thicker sauce.
Salt, pepper, and garlic powder: A splash of Worcestershire sauce or a pinch of paprika adds more classic stroganoff flavor.

How to Make It at a Glance

Brown the ground beef with the onion and mushrooms in a large skillet over medium heat.
Stir in the broth, salt, pepper, and garlic powder.
Simmer for 5 minutes so the flavors come together.
Take the pan off the heat and stir in the sour cream. Serve right away.

Common Mistakes to Avoid

Not browning the beef fully. Let it get some color, and cook it until no pink remains and it reaches 160°F.
Stirring the sour cream into a bubbling pan. High heat can make it separate. Always take the skillet off the heat first.
Skipping the drain. If your beef is very fatty, spoon off some of the grease before adding the broth so the sauce is not oily.
Crowding the mushrooms. Use a large skillet so they brown instead of steam.

Variations

Extra creamy: Add 2 ounces of cream cheese with the sour cream.
More flavor: Stir in 1 teaspoon of Dijon mustard and a dash of Worcestershire with the broth.
Add greens: Toss in a handful of spinach at the end and let it wilt.
Not keto? Serve over egg noodles, rice, or mashed potatoes.

What to Serve With It

For a keto meal, spoon the stroganoff over cauliflower rice, mashed cauliflower, zucchini noodles, or shirataki noodles. Roasted broccoli or green beans make an easy side. A crisp green salad with a simple vinaigrette helps balance the rich, creamy sauce.

Storage and Reheating

Store leftovers in a covered container in the fridge for 3 to 4 days. Reheat gently in a skillet over low heat or in the microwave at half power, stirring often. Add a splash of broth if the sauce has thickened. Avoid high heat, which can make the sour cream split. This dish is best eaten fresh, since sour cream sauces can turn grainy after freezing.

Keto Ground Beef Stroganoff FAQ

Is this stroganoff really keto?
Yes. Ground beef, mushrooms, broth, and sour cream are all low in carbs. The onion adds a small amount, spread across 4 servings.

How can I thicken the sauce without flour?
Simmer it a few extra minutes before adding the sour cream, or stir in a little cream cheese.

Can I use Greek yogurt instead of sour cream?
Yes, but full-fat yogurt is tangier and slightly higher in carbs. Stir it in off the heat.

Can I double the recipe?
Yes. Use a very large skillet or brown the beef in two batches so it browns well.

Tips for the Best Ground Beef Stroganoff

Brown the mushrooms well. Let them cook until their liquid is gone and the edges turn golden. That deep, savory flavor is what makes stroganoff taste like stroganoff.
Break up the beef as it cooks. Small crumbles mix better with the sauce and every bite gets some mushroom.
Let the sour cream warm up. Set it on the counter while you cook. Room temperature sour cream blends in smoothly and is less likely to split.
Finish with fresh herbs. A sprinkle of chopped parsley or dill adds color and a fresh taste.

Budget Tips

This is already a budget-friendly dinner. To save even more, buy ground beef in a family pack and freeze it in 1 pound portions. White mushrooms are cheaper than cremini and taste great here once browned. Beef bouillon mixed with hot water works in place of boxed broth. Cauliflower rice in a frozen bag is often less expensive than fresh heads of cauliflower.

Leftover Ideas

Spoon leftover stroganoff into halved bell peppers, top with cheese, and bake at 375°F for 20 minutes. It also makes a cozy filling for a cheese omelet, or a quick topping for a baked potato if you are not eating keto.
