In a sauce pan over medium high heat, add butter and garlic powder for alfredo sauce. Once melted, whisk in flour and let cook 2 minutes. Whisk in milk and let cook another 2 minutes. Add black pepper and heavy cream. Once combined, add parmesan cheese and whisk until melted. Reduce heat to medium-low and let simmer and thicken.
Add pasta to boiling water and cook as directed on the package. In the last 5 minutes of cook time, add broccoli. Once time is up, drain in colander and return to pots, away from heat. Add alfredo sauce and toss to cook.
In a large saute pan over medium high heat, add butter and minced garlic. Once melted entirely, add pepper, oregano and paprika. Add shrimp to pan and saute until no longer pink.
Serve a portion of the pasta with a portion of shrimp on top. Sprinkle with additional parmesan cheese, if desired.
