Prep: Preheat oven to 350 °F
Place a large skillet over med-high heat and add two tablespoons of EVOO. When the oil is hot, add the onions, celery, peppers, shallots, and garlic. Sauté until the onions are soft and opaque, then set aside.
Once the cornbread is finished baking and cool enough to handle, crumble cornbread into a large bowl, add the sautéed vegetables and seasonings, then mix well.
Spoon the cornbread mixture into a large baking dish and add three cups of chicken stock. [ If you are adding in the bag of Pepperidge Farm Onion & Sage, this is where you will add it.]
Make sure the mixture is moist but not too damp. (if needed, add a little more chicken stock)
Next, slice a half-stick of unsalted butter and press them along the sides of the dish.
Bake in a preheated oven at 350 degrees for one hour.
If the cornbread dressing is browning too quickly, place a sheet of aluminum foil over the pan and continue baking.
