Heat up a pan on medium heat and add your oil and your onion. Fry the onion translucent and add your garlic paste as well. Stir-fry.
Then add your clean shrimps and fry shortly on both sides. Season with black pepper, chili flakes, and oregano.
Pour in the white wine and continue to build up the sauce with the tomato paste and tomato chunks.
Stir occasionally and cook for about 5 minutes so that the ingredients get to mix up and the sauce gets thicker. Garnish with fresh basil before serving.
Serve hot over pasta or risotto rice. You can also serve the shrimp fra diavolo as a stand-alone dish with bread, polenta/grits, and a small salad.
