Ingredients

  • 1 lb (450 g) penne rigate
  • 4 tbsp butter
  • 1 small onion, minced fine
  • 6 tbsp double-concentrated tomato paste
  • ¼ cup (60 ml) vodka
  • ¾ cup (180 ml) heavy cream
  • ¾ cup grated Parmigiano-Reggiano
  • Chili flakes and salt

Instructions

  1. 01

    Sweat the onion. Butter and onion over low heat for eight minutes until soft and sweet, never browned.

  2. 02

    Cook the paste. Add the tomato paste and stir for four full minutes until it darkens to brick red. This is where the flavor comes from.

  3. 03

    Vodka. Pour it in and let it bubble away for a minute — it strips the raw edge off the tomato and carries the aroma.

  4. 04

    Cream and pasta. Cream in, then the penne cooked one minute under, plus a ladle of pasta water.

  5. 05

    Cheese last. Off the heat, stir in the Parmigiano so it melts without splitting.

Larry’s rule: Use tube tomato paste, not canned sauce. Cooking the paste until it darkens is the entire difference between good and forgettable. No vodka in the house? Use water plus a squeeze of lemon — you lose a little sharpness, not the dish. The alcohol simmers off in the pan, and a pound of browned Italian sausage stirred in turns it into sausage vodka pasta.

Before you cook

What to know about Penne alla Vodka

What it is

Penne alla Vodka is a pasta recipe rooted in the direct, savory cooking of Lazio and Rome. This version makes 4 servings in 35 min and focuses on the technique that gives the dish its characteristic texture and flavor.

Why this method works

The method builds flavor in a deliberate order: sweat the onion, then cook the paste, then vodka. Following that sequence keeps the main ingredients distinct while bringing the finished dish together.

Key ingredients and what they do

  • 1 lb (450 g) penne rigate — supports the dish's balance, texture and regional character.
  • 4 tbsp butter — builds the savory foundation and carries flavor through the dish.
  • 1 small onion, minced fine — provides the aromatic character; use it at the stage specified so it stays distinct.
  • 6 tbsp double-concentrated tomato paste — supplies acidity, sweetness and the recipe's tomato base.

Smart substitutions

For the most reliable result, keep the main ingredient and technique unchanged. Swap only like for like, then adjust salt, moisture and cooking time to taste.

Make ahead and leftovers

Prepare the measured ingredients ahead, but cook and sauce the pasta close to serving. Refrigerate leftovers promptly and reheat gently with a splash of water.

What to serve with it

  • Serve as a first course before a simple roast or vegetable dish.
  • Pair with a crisp salad or bitter greens to balance the pasta.

Larry’s why

Why Larry finishes the pasta in the sauce

Draining pasta and ladling sauce on top leaves two separate things on a plate. Pull the pasta a minute shy of al dente, move it into the sauce pan with a splash of the cooking water, and toss over heat. The starch in that water emulsifies the fat and glues the sauce to every strand.

Larry’s rule: Undercook by a minute, finish in the pan.

Home Alone: The Great Sausage Heist

Two masked bandits in black turtlenecks case a suburban kitchen at Christmas, and the only score worth taking is the cured sausage sitting on top of the fridge. A holiday heist parody short from Uncle Larry Adventures — comedy, capers, and one very well-guarded link of Italian sausage.

Quick answer

Why did my risotto turn out gluey?

Gluey risotto usually means too much stirring at too low a heat, or the wrong rice. Use Arborio or Carnaroli, keep the pot at a steady simmer, stir every 30 seconds rather than constantly, and stop while the grains still have a firm center.
