Easy Pesto alla Trapanese Pasta with Tomatoes and Almonds

Pesto alla Trapanese is a fresh Sicilian sauce made with ripe tomatoes, almonds, basil, garlic, olive oil, and grated cheese. Unlike the familiar green pesto from Genoa, this version has a rosy color, a lighter tomato flavor, and a pleasantly coarse texture.

The sauce requires no cooking. Hot pasta is tossed with the pesto away from direct heat, preserving the fragrance of the basil and the bright character of the tomatoes.

This beginner-friendly method skips the traditional tomato-peeling step. Instead, the tomatoes are halved, lightly salted, and briefly drained. That removes loose juice without sacrificing the flesh or flavor, helping the pesto cling to the pasta instead of collecting at the bottom of the bowl.

Ingredient Notes

Tomatoes

Cherry or grape tomatoes are the most practical choice because they are naturally sweet, easy to drain, and less watery than many large slicing tomatoes.

Taste one before starting. If the tomato is bland on its own, it will not produce a strongly flavored pesto.

Ripe plum tomatoes can also work, but remove the loose seed pockets and allow the flesh to drain well.

Almonds

Blanched almonds produce a cleaner color and smoother texture than almonds with their skins attached. Toasting them briefly deepens their flavor, but they should remain lightly golden rather than dark brown.

Pistachios can be used for a variation, although they will noticeably change the flavor and color.

Cheese

Pecorino Romano gives the sauce a salty, savory edge. Parmesan is a practical substitute when a milder cheese is preferred.

Because the pasta water and cheese are both salty, taste the finished pasta before adding more salt.

Pasta

Traditional busiate is ideal because its spiral shape catches the coarse pesto. Fusilli, casarecce, and gemelli are easier to find and work very well.

Choose a pasta with twists, curves, or ridges rather than a completely smooth shape.

Equipment

You will need:

• A large pot
• A colander
• A small dry skillet
• A food processor
• A large mixing or serving bowl
• A silicone spatula
• A fine grater

A mortar and pestle can be used for a more traditional texture, but it is not necessary for this version.

How to Make Pesto alla Trapanese Pasta

1. Drain the tomatoes

Place the halved tomatoes in a colander and toss them with the fine salt.

Leave them to drain for 10 minutes. Shake away the released liquid, but do not rinse the tomatoes.

They should remain plump and juicy while no longer dripping excess liquid.

2. Toast the almonds

Place the almonds in a dry skillet over medium-low heat.

Toast them for about 4–6 minutes, stirring frequently, until they smell nutty and develop light golden spots.

Transfer them to a plate and allow them to cool for at least 5 minutes. Avoid processing them while hot, as the heat can dull the fresh basil flavor.

3. Cook the pasta

Bring a large pot of salted water to a boil.

Cook the pasta until al dente according to the package directions. Before draining, reserve some of the starchy cooking water.

Drain the pasta without rinsing it.

4. Process the almonds and garlic

Place the cooled almonds and garlic in the food processor.

Pulse until the almonds resemble coarse crumbs. Small pieces should still be visible.

Stop before the mixture becomes oily or begins turning into almond butter.

5. Make the pesto

Add the drained tomatoes, basil, and optional red pepper flakes to the food processor.

Pulse in short bursts until the mixture becomes a coarse, rosy pesto. With the machine running briefly, drizzle in the olive oil.

Transfer the pesto to a large bowl and stir in the grated Pecorino.

The sauce should be spoonable and cohesive, with visible flecks of basil and almond. It should not look completely smooth or watery.

6. Toss the pasta off the heat

Add the hot drained pasta to the bowl of pesto.

Pour in about one-third of the reserved pasta water and toss vigorously. Add more water one tablespoon at a time only if the sauce remains too thick.

The finished pesto should cling to the pasta’s ridges and curves without leaving a thin puddle in the bowl.

7. Finish and serve

Taste the pasta before adding any additional seasoning.

Serve it warm with fresh basil, extra grated cheese, and chopped toasted almonds if desired.

Expert Tips

Cool the almonds fully

Warm almonds can heat the basil inside the food processor and mute its fresh aroma.

Use short pulses

Continuous processing can turn the almonds oily and make the tomatoes too liquid. Pulse only until the sauce reaches a coarse consistency.

Add pasta water gradually

Tomatoes vary in moisture. Adding all the reserved water at once may produce a thin sauce that is difficult to correct.

Toss away from direct heat

The pesto is meant to taste fresh rather than cooked. Mix it with the hot pasta in a bowl or in a pot that has been removed from the burner.

Serve promptly

Pasta continues absorbing moisture as it stands. The sauce will be glossiest and most evenly distributed shortly after tossing.

Common Mistakes to Avoid

Using underripe tomatoes: The sauce depends heavily on the tomatoes’ natural flavor.

Skipping the draining step: Excess tomato juice can thin the pesto and prevent it from coating the pasta.

Burning the almonds: Dark almonds may give the sauce a bitter taste.

Overprocessing the pesto: A completely smooth sauce loses the coarse almond texture that makes this recipe distinctive.

Forgetting the pasta water: Its starch helps bind the tomatoes, oil, cheese, and pasta.

Heating the sauce in a skillet: Direct heat can dull the basil and make the fresh tomatoes taste cooked.

Variations

Mild Parmesan version

Replace the Pecorino with finely grated Parmesan for a gentler, less salty flavor.

Spicy version

Increase the red pepper flakes slightly or add a small piece of fresh chile.

Basil and mint version

Replace a small portion of the basil with fresh mint. Keep the mint restrained so it does not overwhelm the tomatoes.

Dairy-free version

Omit the cheese and add a little more finely ground toasted almond. Season carefully, as the cheese normally provides much of the savory flavor.

Serving Suggestions

Serve the pasta with a simple arugula salad, grilled zucchini, roasted eggplant, or sweet roasted peppers.

It also pairs well with grilled chicken or baked white fish when a larger meal is needed.

The pesto can be used separately as a topping for crostini, roasted vegetables, chicken, or fish.

Make-Ahead

The pesto can be prepared up to one day ahead and refrigerated separately from the pasta.

Allow it to stand briefly outside the refrigerator while the pasta cooks, then stir before using. Cook and toss the pasta shortly before serving for the best consistency.

Storage

Store leftover pesto in a clean airtight container in the refrigerator for up to 3 days.

Refrigerate assembled pasta promptly in a covered container and use it within 3–4 days. Its texture and fresh basil flavor will be best during the first 1–2 days.

Do not leave the pesto or pasta at room temperature for more than 2 hours. When the surrounding temperature is above 90°F or 32°C, refrigerate it within 1 hour.

Reheating

Add a small splash of water to leftover pasta before reheating.

Warm it gently in a covered skillet or microwave, stirring partway through. Avoid high heat, which can dry the pasta and weaken the fresh pesto flavor.

Reheated leftovers should reach 165°F or 74°C throughout.

Freezing

The pesto can be frozen without the cheese for up to about 2 months for the best quality.

Freeze it in small airtight portions, thaw it in the refrigerator, and stir in freshly grated cheese before serving.

Freezing the assembled pasta is not recommended because the noodles may become soft after thawing.

Frequently Asked Questions

What is pesto alla Trapanese?

It is a Sicilian pesto from the Trapani area made primarily with fresh tomatoes, almonds, basil, garlic, olive oil, and grated cheese.

Do I need to peel the tomatoes?

No. Cherry and grape tomato skins are thin enough to process directly. Brief draining controls moisture without requiring peeling.

Why is my tomato pesto watery?

The tomatoes may have released too much juice, or too much pasta water may have been added. Stir in a little finely grated cheese or ground toasted almond to thicken it.

What pasta works best?

Busiate is traditional, but fusilli, casarecce, gemelli, rigatoni, and penne all hold the coarse pesto well.

Can I use Parmesan instead of Pecorino?

Yes. Parmesan creates a milder, less salty sauce and can replace Pecorino in the same role.

Can I prepare the pesto in advance?

Yes. Refrigerate it in a sealed container for up to one day before combining it with freshly cooked pasta.

Can pesto alla Trapanese be served cold?

Yes. It can be served cool or at room temperature, although the pasta may need a small splash of water or olive oil after refrigeration.

Pesto alla Trapanese offers a fresh alternative to both cooked tomato sauce and traditional green pesto. The key is preserving its coarse texture, draining the tomatoes well, and using only enough pasta water to create a sauce that clings.
