Heat a pan over medium high heat (I have a slow cooker that has a stovetop function so I just do this step right in my slow cooker). Add in the oil, onion, celery and mushrooms. Saute for 3 minutes. Add in the garlic and saute for 30 seconds. Stir in the flour to coat. Transfer the mixture to the slow cooker.
Pour in the broth and stir. Stir in the carrots, seasoned salt, pepper, paprika, Worcestershire, stew meat and potatoes.
Cover slow cooker and cook on high for 3 hours or on low for 5 hours.
Stir in a splash of red wine vinegar. Salt to taste, if needed. If desired stir in a cup of peas.
Hollow out sourdough bread bowl. Use the hollowed out portion and a couple of toothpicks to create mickey ears on the bread bowl. Ladle soup into bread bowl. Enjoy!
