Season Beef: Place the thinly sliced beef sirloin in the slow cooker. Season with sea salt and optional garlic powder.
Add Broth: If using, pour the beef broth over the beef to help maintain moisture during cooking.
Slow Cook: Cover and cook on low for 4-5 hours, or until the beef is tender.
Add Sour Cream: In the last 30 minutes of cooking, stir in the sour cream. Continue cooking until heated through and the sauce is creamy.
Final Seasoning: Adjust the seasoning with additional salt if needed before serving.
Serve: Serve the Carnivore "Beef Stroganoff" hot, ideally over a bed of buttery scrambled eggs
