Cut the bread into cubes or tear into bite-sized pieces. Preheat the oven to 350 degrees Fahrenheit. Add the bread cubes to a baking sheet.
Once the oven is up to temperature, cook the bread for about 20 minutes, until the bread is dried out and crisp. Remove from the oven and increase the heat to 375 degrees Fahrenheit.
Meanwhile, finely chop the onion and celery.
Roughly chop the parsley.
Slice the sage leaves.
Cook the bacon in a skillet over medium heat. Do not pour off the bacon grease.
Remove the bacon from the pan and crumble or chop when cool.
Add the butter to the bacon grease and melt. If the butter starts to get dark, turn down the heat a bit. Scrape up any browned bits in the pan.
Whisk in the sage and poultry seasoning.
Once melted, sauté the onion and celery for 3 to 5 minutes, until the onion is soft and translucent.
Add the broth to the skillet, mix well, and season to taste.
Add the bacon and parsley to the bread mixture in a baking dish or casserole dish. Mix until thoroughly combined.
Pour the vegetable and broth mixture over the bread. Bake it in the oven for 10 to 15 minutes to make the top of the bread crispy and golden brown. Do not cover the stuffing when cooking.
Serve hot!
