Easy Low Carb Beef Stew

Place the slow cooker insert on the stove and melt the butter. Sauté onions, carrots, and celery until soft. Add the garlic, spices, and dried herbs, then stir. Remove from the pan and set aside while you sear the beef. Season beef with salt and pepper to taste. Add beef to the slow cooker on the stove and cook until browned, about 3 minutes. Place the sautéed veggies back in the pan, add the potatoes and mushrooms. Pour in the beef stock, water, tomato paste, bay leaf, and thyme. Stir to combine, then add the pot back onto the slow cooker. Set to high for 4 hours or low for 8 hours. During the last 5 minutes, stir in the peas. Discard bay leaf and thyme sprigs. Serve in bowls and garnish with parsley. Enjoy!
