Boil a large pot of salted water and cook the spaghetti pasta al dente according to the package instructions.
While the pasta is cooking, make the marinara sauce. Heat the extra virgin olive oil in a skillet on medium heat and add the chopped garlic.
Once the garlic starts to smell, add the shrimp and cook for 2 minutes until almost cooked. Remove the shrimp from the pan and set aside.
In the same pan, stir in the tomatoes, oregano, and red pepper flakes. Add some basil leaves and reduce the heat to low. Let the sauce simmer for at least 15 minutes.
Drain the cooked pasta and add to the marinara sauce. Combine the pasta with the sauce, top with the cooked shrimp, then serve in bowls or plates. Garnish with some fresh basil leaves. Enjoy!
