The Magic of Pasta alla Crudaiola

This recipe for No-Cook Tomato Sauce is a perfect example of a beloved Italian summer tradition. Pasta alla Crudaiola is all about using the residual heat from freshly cooked pasta and its starchy cooking water to create an “instant” sauce from raw, fresh ingredients.

Instead of simmering a sauce in a separate pan, all the components are combined in a large serving bowl. The steaming hot pasta is then added directly to the bowl. The heat from the pasta gently warms the tomatoes, wilts the basil, and blooms the flavor of the garlic, while the starchy pasta water works its magic to create a light, glossy, and beautifully emulsified sauce. It’s a brilliant, efficient, and incredibly delicious technique.

The Grated Tomato Trick: An Instant Sauce Base

The secret to creating a sauce with body and texture without any cooking is the grated tomato technique. By taking a large, juicy beefsteak tomato and grating it on the coarse side of a box grater, you instantly create a fresh, pulpy tomato puree. The tough outer skin is left behind, and you’re left with a perfect, uncooked sauce base. This is combined with chopped heirloom tomatoes for a fantastic mix of smooth puree and chunky texture in your No-Cook Tomato Sauce.

The Key Ingredients for Your No-Cook Tomato Sauce

The success of this simple dish relies entirely on the quality and freshness of your ingredients. This is the time to use the best you can find.

• The Tomatoes: This is the most important ingredient. For the best No-Cook Tomato Sauce, use a combination of two types of ripe, in-season tomatoes:
  • Beefsteak Tomatoes: One large, juicy beefsteak tomato is perfect for grating to create the pulpy sauce base.
  • Heirloom Tomatoes: Two medium heirloom or a pint of colorful cherry tomatoes, chopped, provide a beautiful color and a firm, chunky texture.
• Good Extra-Virgin Olive Oil: Since the oil is a primary, uncooked component of the sauce, using a high-quality, fruity, and flavorful extra-virgin olive oil will make a huge difference.
• Fresh Garlic & Basil: Essential for that classic, aromatic Italian flavor.
• Rigatoni Pasta: The large, ridged tubes of rigatoni are perfect for catching the light, chunky sauce.
• Freshly Grated Parmesan Cheese: The final touch of salty, nutty, savory flavor. Always grate it yourself from a block for the best results.

Step-by-Step Guide to Your No-Cook Tomato Sauce Pasta

This elegant meal comes together in about 15 minutes. The only cooking required is boiling the pasta!

1. Boil the Pasta Water: Bring a large pot of generously salted water to a rolling boil.
2. Prepare the Sauce Bowl: While the water heats up, prepare your sauce. Grate the large beefsteak tomato on the coarse holes of a box grater into a very large serving bowl. Discard the skin.
3. Combine Sauce Ingredients: To the bowl with the grated tomato, whisk in the 1/4 cup of olive oil, the 1 grated clove of garlic, and 1 teaspoon of kosher salt. Stir in the chopped heirloom tomatoes and the torn fresh basil leaves. Your No-Cook Tomato Sauce base is now ready.
4. Cook the Pasta: Add the rigatoni to the boiling water and cook according to the package directions until it is al dente (tender but still has a firm bite).
5. The Most Important Step: Reserve Pasta Water! Just before draining the pasta, use a mug to carefully scoop out and reserve at least 1 cup of the hot, starchy pasta water. Then, drain the pasta well.
6. Assemble and Create the Sauce: Immediately add the hot, steaming pasta directly into the serving bowl on top of the raw tomato sauce ingredients.
7. Toss Vigorously: Add the 1 1/2 cups of grated Parmesan cheese and about 1/2 cup of the reserved hot pasta water to the bowl. Use tongs or two large spoons to toss everything together vigorously for about a minute. The heat will melt the cheese, and the starchy water will emulsify with the oil to create a light, creamy, glossy sauce that clings to the pasta. If the sauce seems too dry, add another splash of pasta water until it reaches your desired consistency.
8. Serve: Season your finished pasta to taste with more salt and pepper. Serve immediately in large bowls, topped with extra fresh basil and more grated Parmesan.
