Heat butter in a large, wide nonstick pot or pan over medium-high heat until melted.
Add onion, garlic, celery, and cook until garlic is fragrant. This takes about 2 minutes.
Add sausage and 1/2 tbsp poultry seasoning, salt, pepper and cook until well-browned. Stir often for about 5 minutes.
Remove from heat and add dried bread cubes and mix it with the sausage and veggies.
Pour whisked egg and broth over the stuffing.
Sprinkle remaining poultry seasoning and mix everything until combined.
Bake uncovered at 350 degrees F for 35-45 minutes or until top is crispy and golden brown.
Garnish with fresh parley or green onions.
Serve immediately and enjoy!
For a better presentation, especially for Thanksgiving or a dinner party, spread the dried bread cubes in a rectangle casserole dish (Dimensions: 9x16). Cook the sausage and veggies on the side and mix that with the bread cubes, along with remaining seasoning, whisked egg, broth. Then, bake until golden brown.
Notes
Read all my tips above.
My mom likes to use a fork fluff the mixture, prior to serving but I prefer the whole bread cubes and skip this step.
Tastes best when served fresh but leftovers can be stored in a sealed container in the fridge for up to 2 days and reheated in the oven or microwave.
