Cook pasta according to directions.
In a separate heated pan on medium-low flame, add a little extra virgin olive oil and minced garlic. Cook until garlic has turned a slight golden color. Then add in your sausage coins.
Cook sausage for approximately 16-20 minutes, or until thoroughly cooked. Remove from heat.
In a medium sized pot, add in heavy cream, butter, salt, pepper, and cajun seasoning.
With a whisk, light turn until heavy cream has heated. This should take about 3 minutes, Do NOT scorch or wait until boiling. We don't want it to boil. Once heated, add in parmesan cheese and stir gently. Continue to stir until cheese has melted throughout. Once melted throughout, remove from heat.
Add in the cooked pasta and sausage. Mix well so that all of the pasta is evenly coated. Let stand for a minute before serving.
