The Story Behind Spaghetti alla Checca
This classic Roman pasta recipe comes from La Sora Checca, a now-legendary food stall in Rome where the dish first gained popularity. The name is a diminutive form of Francesca—“Checca”—and the sauce, made with raw tomatoes, fresh basil, and mozzarella, has become a staple in Italian recipes every summer since. Think of it as a cold sauce that’s transformed by tossing it with hot pasta—simple, smart, and so flavorful.
Ingredients
The most important thing here is your tomatoes. You want perfectly ripe, plump cherry tomatoes — this is not the recipe for sad, mealy ones. The marinade does the heavy lifting: once the tomatoes sit with garlic, olive oil, salt, and pepper for a full 30 minutes, the juices release and you have a proper no-cook sauce ready to go. Fresh mozzarella is equally important; tear it into small pieces so it can soften and melt into the hot pasta when everything comes together. And use good olive oil — in a recipe this simple, every ingredient matters.
Step by Step Instructions
- Marinate the tomatoes. In a serving bowl, combine tomatoes, olive oil, garlic, salt, pepper, and red pepper flakes.
2. Let the tomato mixture sit at room temperature for at least 30 minutes while the flavors develop.
3. Bring a large pot of water to a boil, season generously with salt, and cook pasta according to package instructions until just al dente. Reserve a bit of pasta water before draining.
4. Add the drained hot pasta to the basil mixture and toss well, adding reserved pasta water a little at a time until a silky sauce forms.
5. Fold in mozzarella balls and fresh basil.
6. Drizzle in balsamic vinegar and add lemon zest if using. Toss gently and serve warm or at room temperature.

Pasta alla Checca (No-Cook Tomato Sauce)
Equipment
- Large pot
- Large serving bowl
- Tongs or pasta spoon
- Fine grater or microplane
- Measuring Cups and Spoons
- Small knife and cutting board
Ingredients
- 8 ounces pasta spaghetti, angel hair, or short pasta like fusilli
- 3 cups cherry tomatoes halved
- 3 tablespoons extra virgin olive oil
- 1 large garlic clove finely minced or grated
- ¾ teaspoon kosher salt
- ½ teaspoon freshly ground black pepper
- ¾ teaspoon red pepper flakes optional
- 6 ounces fresh mozzarella torn
- ¾ cup fresh basil leaves torn
- 1½ teaspoons balsamic vinegar optional
- Zest of 1 lemon optional
Instructions
Marinate the tomatoes
- In a large serving bowl, combine the cherry tomatoes, olive oil, garlic, salt, black pepper, and red pepper flakes (if using). Give everything a gentle toss and let the mixture sit at room temperature for at least 30 minutes. This gives the flavors time to come together and makes the base of your uncooked sauce.3 cups cherry tomatoes, 3 tablespoons extra virgin olive oil, 1 large garlic clove, ¾ teaspoon kosher salt, ½ teaspoon freshly ground black pepper, ¾ teaspoon red pepper flakes
Boil the pasta
- Bring a large pot of water to a boil and salt it generously. Cook your pasta according to package directions until just al dente. Before draining, scoop out about ¾ cup of pasta water and set it aside.8 ounces pasta
Combine the pasta and sauce
- Add the hot pasta straight into the bowl with the marinated tomato mixture. Use tongs or a spoon to toss it together, letting the heat gently warm the sauce. Add a splash or two of pasta water as needed to help it all come together.
Add the mozzarella and basil
- Fold in the torn mozzarella and fresh basil. Drizzle in the balsamic vinegar and add the lemon zest, if using. Toss everything once more—gently—and taste for seasoning.6 ounces fresh mozzarella, ¾ cup fresh basil leaves, 1½ teaspoons balsamic vinegar, Zest of 1 lemon
Serve
- Plate the pasta and finish with an extra drizzle of olive oil and a few more basil leaves if you’d like. Enjoy right away, or let it sit for a few minutes to soak up even more flavor.
Notes
- Let the tomatoes marinate for the full 30 minutes. This is the most important step. The salt draws out the tomato juices and the garlic and olive oil infuse into a proper no-cook sauce. Don’t rush it.
- Use the best olive oil you have. This is a recipe where olive oil is a flavor ingredient, not just a cooking medium. A grassy, peppery extra virgin olive oil makes a real difference.
- Don’t rinse your pasta. The starch on the noodles is what helps the sauce cling. Rinsing it washes that away.
- Add pasta water slowly. A splash at a time gives you control over the texture. You want silky, not soupy.
- Storage: Refrigerate leftovers in an airtight container for up to 2 days. This dish is best served at room temperature the next day — pull it out of the fridge 30 minutes before serving and drizzle with a little extra olive oil to loosen. Do not reheat in the microwave.
