Preheat oven to 230°F. Slice approximately 3/4 inch from the top of the cob loaf. Hollow out the interior, reserving the bread pieces. Place the loaf shell, lid, and torn bread on a parchment-lined baking sheet. Bake for 5–10 minutes until lightly toasted.

In a medium saucepan over medium-high heat, sauté chopped bacon and onion for 3–5 minutes until the bacon is browned and the onion is softened.

Reduce heat to low. Add cream cheese and sour cream to the pan, stirring until fully melted and blended. Mix in the French onion soup mix, optional brie cheese pieces, and all but a handful of shredded pizza cheese. Stir constantly until smooth and heated through, about 2 minutes.

Remove the bread from the oven. Increase oven temperature to 400°F. Set the lid and bread pieces aside. Pour the hot cheese mixture into the hollowed loaf, then sprinkle the reserved cheese on top. Return the filled loaf to the oven and bake for 10 minutes, or until the top is golden and bubbling.

Transfer the loaf to a serving platter. Arrange toasted bread pieces and cut-up lid around the dip. Serve immediately and encourage guests to dip bread into the warm, cheesy center.
