Prep: 7 min | Cook: 18 min | Total: 30 min

Cost: $5.55 total, $2.78 per serving

Ingredients

  • 200 g Fettuccine Pasta (dry, break in half if very long)
  • 2 tablespoons Unsalted Butter (cut into cubes for quick melting)
  • 100 g Parmigiano‑Reggiano Cheese (real Italian Parmigiano‑Reggiano, grated super fine)
  • 1 tablespoon Salt (for the pasta water)
  • 1 cup Pasta Water (reserved from cooking water; helps emulsify the sauce)

Instructions

  1. Cook Pasta

    Bring a large pot of water to a rolling boil, add 1 tablespoon salt, then add the fettuccine. Cook until al dente, about 9‑10 minutes.

    Time: PT10M

    Temperature: boiling

  2. Shred Cheese

    While the pasta cooks, grate the Parmigiano‑Reggiano as fine as possible using a microplane or fine grater.

    Time: PT2M

  3. Prep Butter

    Cut the unsalted butter into small cubes and set aside.

    Time: PT1M

  4. Reserve Pasta Water

    Before draining, ladle out 1 cup of the hot pasta cooking water and set aside.

    Time: PT1M

  5. Drain Pasta

    Drain the fettuccine in a colander and return it to the pot (or a warm bowl) while you finish the sauce.

    Time: PT1M

  6. Melt Butter

    Heat the large skillet over medium heat and melt the butter cubes until just foaming, not browned.

    Time: PT1M

    Temperature: medium

  7. Combine Pasta and Butter

    Add the drained fettuccine to the skillet, splash in a little reserved pasta water, and toss to coat the noodles in butter.

    Time: PT2M

    Temperature: medium

  8. Create the Alfredo Sauce

    Sprinkle the grated Parmigiano‑Reggiano over the pasta a handful at a time, stirring continuously. Add more pasta water a little at a time until the sauce reaches a velvety, glossy coating.

    Time: PT4M

    Temperature: medium

  9. Finish Toss

    Continue tossing for another minute to ensure every noodle is evenly coated and the sauce is smooth.

    Time: PT1M

    Temperature: medium

  10. Plate and Serve

    Transfer the fettuccine to plates, garnish with an extra sprinkle of grated Parmigiano‑Reggiano, and serve immediately.

    Time: PT2M

  • • Grate Parmigiano‑Reggiano super fine for a smooth emulsion.
  • • Add the cheese gradually while stirring, using pasta water to adjust consistency.
