Cook the spaghetti in salted boiling water, per instructions.
Drain the pasta making sure to keep 1/4 cup of the pasta cooking water.
When the pasta has nearly finished cooking, heat the olive oil in a large sauté pan over medium high heat.
Add the thin slices of garlic and the crushed red pepper flakes then toss quickly to coat them completely.
Cook, stirring constantly for 1-2 minutes, or until the garlic just starts to get golden.
Add the drained spaghetti to the garlic and oil and a bit of the pasta water; toss to coat evenly.
Add the fresh parsley and season well with sea salt and freshly cracked pepper, to taste.
Serve immediately. Enjoy.
