Make the roux: Get out a 4 to 6-quart pot place it over medium-high heat and add in the oil. Once the oil is hot add in the flour and quickly whisk the ingredients are together, we don't want any lumps! Then keep whisking the mixture for 15 to 20 minutes until it forms into a brown roux.
Saute the vegetables: Toss in the onion, celery and bell pepper and mix them into the roux. Then sautee them for roughly 4 to 5 minutes. Toss in the garlic and continue sauteing for another minute.
Add the stock and seasonings: Slowly pour the stock into the pot making sure the roux gets mixed into the stock. You can also add more stock if you prefer the sauce to be a little bit thinner. Finally, add the seasoning and paprika stirring them into the sauce.
Add and cook the shrimp: Toss in the shrimp, stir them into the sauce and let them simmer for roughly 7 to 10 minutes.
Plate the shrimp etouffee: Get out a large flat bowl and mound some rice into the middle of it. Then pour some of the shrimp along with the sauce around the rice. Finally garnish the dish with some chopped parsley leaves, green onion, and a couple of shakes of your favorite hot sauce.
Enjoy!
