Chop bacon into 1-inch pieces and add to a large pot. Turn on medium heat and cook the bacon until crisp. Use a slotted spoon to remove and set aside for now.
Season beef with pepper. Add beef to the bacon grease and cook until all sides are browned. Remove beef with a slotted spoon and set aside.
Add onion, celery, and carrot to the pot. Cook for about 3-4 minutes, or until the vegetables start to get tender. Add the garlic and cook for an additional minute.
Add red wine and cook for 2-3 minutes or until reduced by half.
Add in the tomato paste, stock, and rosemary to the pot. Add beef and bacon back as well.
Cover and reduce heat to low. Let simmer for 1 hour, then remove the lid and simmer uncovered for 30 minutes or until the stew reaches your desired consistency. Enjoy.
