This Keto Beef Stroganoff is a creamy, low-carb twist on the classic Russian dish, featuring tender slices of beef sirloin cooked with mushrooms and onions in a rich, flavorful sauce made with beef broth, heavy cream, and Dijon mustard. Perfectly paired with zucchini noodles or cauliflower rice, this recipe is ideal for anyone following a ketogenic diet seeking a comforting and nutritious meal.

Ingredients

Beef and Sauce:

  • 1 lb (450g) beef sirloin, thinly sliced
  • 2 tablespoons olive oil
  • 1 medium onion, diced
  • 2 cloves garlic, minced
  • 8 oz (225g) mushrooms, sliced
  • 1 cup beef broth
  • 1 cup heavy cream
  • 1 tablespoon Dijon mustard
  • 1 teaspoon Worcestershire sauce (optional)
  • Salt and pepper to taste

To Serve:

  • Zucchini noodles or cauliflower rice
  • Fresh parsley, chopped (for garnish)

Instructions

  1. Brown the Beef: Heat olive oil in a large skillet over medium-high heat. Add the thinly sliced beef and cook, stirring occasionally, until browned on all sides, about 3-4 minutes. Remove the beef from the skillet and set aside to prevent overcooking.
  2. Sauté Onion and Garlic: In the same skillet, add the diced onion and minced garlic. Cook over medium heat until the onion is softened and translucent, about 2-3 minutes, stirring frequently to avoid burning the garlic.
  3. Cook Mushrooms: Add the sliced mushrooms to the skillet with the onions and garlic. Continue cooking until the mushrooms release their moisture and turn golden brown, about 5 minutes. Stir occasionally to ensure even cooking.
  4. Add Beef Broth and Simmer: Pour in the beef broth, scraping up any browned bits stuck to the bottom of the skillet. This will add deep flavor to the sauce. Bring the mixture to a gentle simmer.
  5. Make the Sauce: Stir in the heavy cream, Dijon mustard, and Worcestershire sauce if using. Season the sauce with salt and freshly ground black pepper to taste. Mix thoroughly to combine all ingredients.
  6. Reintroduce Beef and Finish Cooking: Return the browned beef to the skillet. Reduce the heat to medium-low and simmer everything together for about 5 minutes. This allows the beef to heat through and the sauce to thicken slightly, blending all flavors.
  7. Serve: Plate the beef stroganoff over prepared zucchini noodles or cauliflower rice. Garnish with freshly chopped parsley for a bright, fresh finish. Serve immediately while hot.

Notes

  • For a thicker sauce, you can reduce the cream slightly by simmering longer or add a small amount of xanthan gum suitable for keto diets.
  • Worcestershire sauce is optional but adds a nice depth of flavor; ensure it fits your dietary preferences.
  • Using zucchini noodles or cauliflower rice keeps the dish low carb and keto-friendly compared to traditional egg noodles.
  • Be careful not to overcook the beef to keep it tender and juicy.
  • Fresh parsley adds color and a fresh flavor contrast, but you can substitute with chives or basil if preferred.
