THE METHOD
1

Bring a large pot of water to a boil. Salt it heavily — it should taste like the ocean.

2

Cook the spaghetti until just al dente (1 minute less than the package says). Reserve 500 mL of pasta water before draining.

3

While the pasta cooks, heat olive oil in a large skillet over medium-low heat.

4

Add the garlic slices. Cook slowly, stirring often, for 4–5 minutes until lightly golden. Do not let it brown — burnt garlic ruins the dish.

5

Add the chili flakes. Stir for 30 seconds.

6

Add the drained pasta directly to the skillet. Add 125 mL of pasta water and toss vigorously over medium heat.

7

Add pasta water a splash at a time until you have a loose, silky sauce that coats the noodles. This takes 1–2 minutes of tossing.

8

Remove from heat. Add half the parmesan and toss again.

9

Serve immediately with remaining parmesan and parsley if using.

When the math doesn't work

Pasta water is the actual sauce here — the starch emulsifies with the oil. Don't skip it or rush the tossing step.

  • This is one of the cheapest meals you can make that doesn't taste like it. Total cost under $4 for four people.
  • Use the cheapest spaghetti available. No Frills and Walmart house brands work perfectly.
  • If parmesan is too expensive, nutritional yeast (2 tbsp per serving) works as a vegan substitute and costs less.
