Melt the butter in a large frying pan and add the leeks, carrots, mushrooms, and celery and cook them until they’re tender (about 5 minutes). Once the vegetables are cooked, remove the pan from the burner and stir in the thyme and pepper.
Pop the bread crumbs and bacon in a 6-quart slow cooker. Add the vegetables along with the chicken broth and wine. Give it a gentle stir until the bread cubes are evenly moist. Cook on low for 3.5 – 4 hours.
