Preheat oven to 350 degrees.
Slice open the boudin casing and peel it away. Crumble the boudin stuffing with your fingers into a bowl and set aside.
Combine cream cheese (softened) and the sour cream in a large bowl and mix until smooth either with a spoon, spatula, or hand mixer.
Add the boudin, shredded cheese, 2 tablespoons of the green onions, and optional spice to the cream cheese mixture and stir to combine.
Transfer the mixture to a baking dish. (approximately 1 qt.)
Bake at 350 degrees uncovered for 20-30 minutes, until warmed all the way through.
Garnish with remaining green onions and bacon crumbles if desired.
