Bring a large pot of lightly salted water to a boil. Cook bow tie pasta at a boil, stirring occasionally, until tender yet firm to the bite, about 12 minutes. Reserve 1/2 cup pasta water when draining.

Heat oil in a large deep skillet over medium-low heat. Add sausage and cook, stirring occasionally, until fat is rendered and sausage is browned, about 3 minutes. Increase heat to medium-high; add seasoning blend and Cajun seasoning and cook until vegetables are softened, about 4 minutes.

Stir in heavy cream and bring to a simmer. Cook, stirring occasionally until slightly thickened.
