I start by boiling a large pot of salted water and cooking the spaghetti until al dente. I always reserve a cup of pasta water before draining, which comes in handy for the sauce.
In a skillet, I heat olive oil over medium heat and add minced garlic. It only takes about 1–2 minutes until fragrant, but I make sure it doesn’t burn.
Next, I stir in lemon zest, lemon juice, and a pinch of red pepper flakes. The mixture brightens up instantly and smells amazing in my kitchen.
I add the drained pasta to the skillet and toss well. A splash of reserved pasta water helps coat each strand beautifully with the garlicky lemon goodness.
Finally, I remove the skillet from heat and mix in grated Parmesan and chopped parsley. A few cracks of black pepper on top give it the perfect finish.
