Toast the Bread -Set the oven rack to the lower and upper-middle position. Heat oven to 275°F (135ºC). Cut the bread into ½ inch cubes. Distribute the bread cubes in one layer over 2 baking sheets. Bake for 25 to 35 minutes, stirring after 15 minutes, until lightly browned and crunchy. Transfer to a large bowl.
Cook the Sausage - Heat the olive oil in a large skillet over medium-high heat. Add the sausage, breaking apart with a spoon. Cook for 5 to 7 minutes, until browned.
Cook the Aromatics and Pears - Reduce the heat to medium. Add the onions and garlic, saute for 5 minutes. Add the pears and cook for 2 minutes.
Add the Stock and Cream - Stir in the stock, scraping the bottom of the pan to release brown bits. Mix in pecans, thyme, sage, salt and pepper. Turn off the heat and stir in the cream.
Combine the Stuffing Ingredients - Pour the sausage stuffing mixture into a bowl with the toasted bread, stir until well combined. Allow to soak for 5 minutes.
Bake the Stuffing - Evenly spread the stuffing to a greased 11x7-inch or 9x9-inch casserole dish. Place the dish on a large sheet pan. Cover the dish with foil and bake for 20 minutes. Uncover and bake 5 minutes. Serve warm.
