Start by browning the beef in the Instant Pot with a bit of butter, ensuring it gets a nice sear. This helps develop a rich flavor and gives the beef a savory base.

Once the beef is browned, add the onions, garlic, and mushrooms. Sauté everything together for about three minutes, letting the mushrooms soften and the onions and garlic become fragrant.

Deglaze the pot with beef broth. This step lifts any browned bits from the bottom of the pot, which adds extra depth to the dish.

Secure the lid on the Instant Pot, set it to cook on high pressure for 15 minutes. This ensures the beef becomes tender and absorbs all the rich flavors from the broth, mushrooms, and spices.

After the cooking time is up, carefully release the pressure and open the lid. Stir in the heavy cream, sour cream, and the remaining butter. This gives the dish its creamy texture and rich flavor.

Once everything is well combined, your Keto Instant Pot Beef Stroganoff is ready to serve. Enjoy the creamy, flavorful dish!
