While preparing the other ingredients, combine packet of Lipton Onion Soup Mix and the 3 cups of boiling water. Mix well and allow it to sit.
In a large pot over medium heat, melt 1.5 sticks of butter. Add Pepperidge Farm Herb-Seasoned Classic Stuffing and stir until coated in butter. Add in onion soup + water mixture, parsley, rosemary, sage, thyme, and garlic powder; cook for 3-5 minutes. Fold in the chopped oysters and cooked breakfast sausage. Add stuffing to a greased baking dish and bake for 40 minutes.
Remove from oven, garnish with additional parsley if desired, and enjoy!
Notes
Let the onion soup mix fully dissolve in the boiling water — giving it a few minutes to sit deepens the flavor and helps it absorb evenly into the stuffing.
Chop the oysters into small pieces so they integrate smoothly without overpowering any bite.
Cook the sausage until it’s deeply browned; the crispy edges add richness and texture throughout the dish.
Make it ahead: assemble the stuffing (without baking), cover tightly, and refrigerate up to 24 hours. Add 5–10 minutes to the bake time.
