Fill a large pot with generously salted water and bring to a boil. Cook spaghetti for about 8-10 minutes until al dente.

In a skillet, heat olive oil over medium heat until shimmering and fragrant.

Add garlic flakes and red pepper flakes. Sauté for about 1 minute until garlic is golden.

Drain cooked spaghetti, reserving a cup of pasta water. Add spaghetti to the skillet and toss in the garlic-infused oil.

If needed, add reserved pasta water gradually until the sauce reaches desired consistency.

Sprinkle in dried parsley, black pepper, and salt to taste. Toss gently to combine.

Serve immediately, with optional garnishes of Parmesan cheese or fresh parsley.
