This is a keto-friendly version on my cabbage beef stew - the perfect comfort food! Feel free to add hot sauce.
Season beef with salt and pepper. Heat a large skillet over medium-high heat. Cook beef in batches until browned on at least 2 sides, about 5 minutes per batch. Avoid overcrowding the skillet so beef browns and doesn't steam.
Add browned beef, broth, mushrooms, and bay leaves to a large pot. Cover and simmer until beef is tender, at least 1 hour and up to 2 hours.
Add cabbage, diced tomatoes, onions, tomato paste, and celery. Cook for at least 1 hour more.
