Instructions
Bring a large pot of salted water to a boil and cook the pasta until al dente. Reserve 1/2 cup of pasta water before draining.
While the pasta cooks, warm the olive oil in a skillet over low heat. Add the minced garlic (if using) and let it gently soften without browning.
Add the drained pasta directly into the skillet and toss to coat it in the warm olive oil.
Sprinkle in the freshly grated Parmesan, adding a splash of pasta water as needed to help it melt into a silky sauce.
Season with salt, black pepper, and red pepper flakes to taste.
Toss in fresh parsley if you’re feeling fancy, then taste and adjust seasoning.
Serve immediately while it’s warm, glossy, and comforting.
