Cook the chopped bacon in a big pan until crispy. Put the bacon in your slow cooker.
Sprinkle the beef chunks with salt and pepper. Cook them in the same pan with the bacon grease until they're brown on all sides (about 2-3 minutes per side). Put the browned beef in the slow cooker.
Pour the wine into the hot pan and scrape all the brown bits off the bottom with a wooden spoon. Let it bubble for a minute, then pour in the broth, tomato sauce, and soy sauce. Stir in the flour. Pour this sauce into your slow cooker.
Add the garlic, thyme, carrots, potatoes, and mushrooms to the slow cooker. Stir everything together.
Cover and cook on LOW for 8 hours or until the meat is super tender.
Taste and add more salt and pepper if needed. Sprinkle with parsley if you want it to look fancy!
Serve in bowls, over mashed potatoes, or with crusty bread for dipping.
