Step‑by‑Step Instructions for Trenette al Pesto
Step 1: Toast the Pine Nuts
In a skillet over medium heat, add a handful of pine nuts. Toast them for about 3–5 minutes, stirring frequently, until they are golden brown and fragrant. Be careful not to burn them, as they can scorch quickly. Once toasted, remove from heat and allow them to cool slightly while you prepare the pesto.
Step 2: Blend the Pesto Ingredients
In a food processor, combine the toasted pine nuts, fresh basil leaves, garlic, Parmesan cheese, and a pinch of salt. Pulse until the mixture is coarsely chopped. As you blend, gradually drizzle in extra virgin olive oil until the pesto reaches a smooth and creamy consistency. Scrape down the sides as needed to ensure everything is well incorporated, then set the pesto aside.
Step 3: Boil the Potatoes
Fill a large pot with water, add a generous pinch of salt, and bring it to a boil over high heat. Once boiling, add peeled and diced gold potatoes and cook for 6 minutes. The potatoes should begin to soften but still hold their shape and not fully cook through, as they will finish cooking with the green beans in the next step.
Step 4: Add the Green Beans
After the potatoes have cooked for 6 minutes, carefully add the trimmed green beans to the pot. Continue to boil for an additional 4 minutes, or until both the potatoes and green beans are tender yet crisp. They should have a bright color, indicating they’ve been cooked properly. Use a slotted spoon to remove the vegetables from the pot, transferring them to a large bowl, and set aside.
Step 5: Cook the Trenette Pasta
In the same pot of boiling water, add the trenette pasta (or your preferred alternative). Follow the package instructions, cooking until the pasta reaches al dente, generally around 8–10 minutes. Stir occasionally to prevent sticking. Once cooked, reserve about 1 cup of the pasta water, then drain the pasta in a colander.
Step 6: Combine the Ingredients
In a large mixing bowl, combine the drained pasta with the cooked potatoes and green beans. Pour the previously prepared pesto over the top. Using tongs, gently toss everything together, ensuring each piece of pasta and vegetable is well coated with the vibrant green pesto.
Step 7: Adjust the Consistency
If the mixture seems too thick, gradually add the reserved pasta water a few tablespoons at a time while continuing to toss until you’ve reached your desired creamy consistency. The trenette al pesto should be delightful and luscious without being overly heavy. Check for seasoning and adjust salt to taste.
Step 8: Serve and Enjoy
Plate the trenette al pesto, garnishing with a sprinkle of freshly grated Parmesan cheese and a drizzle of olive oil if desired. Serve warm and enjoy the comforting flavors of this homemade dish that brings a taste of Liguria to your table.

Trenette al Pesto Recipe FAQs
How do I choose the best basil for my pesto?
Absolutely! Look for fresh basil leaves that are vibrant green and free from blemishes or dark spots. The leaves should feel pliable and have a strong, aromatic scent. Avoid wilted or yellowing leaves, as they can compromise the flavor of your homemade pesto.
What is the best way to store Trenette al Pesto leftovers?
Store any leftover trenette al pesto in an airtight container in the fridge for up to 2 days. To keep the pesto fresh and vibrant, drizzle a thin layer of olive oil over the surface before sealing. This prevents oxidation and browning, ensuring your dish remains appetizing!
Can I freeze my Trenette al Pesto?
Very much! For optimal freezing, portion your trenette al pesto into single-serving containers or freezer bags, ensuring to remove as much air as possible. You can freeze it for up to 2 months. When ready to enjoy, simply thaw overnight in the fridge or reheat gently in the microwave, adding a splash of reserved pasta water, if needed, to restore creaminess.
What should I do if my pesto is too thick?
If you find your pesto is thick after combining it with the pasta, don’t worry! Start by adding a small amount of the reserved pasta water, a tablespoon at a time, while tossing to combine. This will help loosen the sauce, creating a smoother, creamier consistency. Adjust until you reach your desired texture.
Is Trenette al Pesto safe for those with nut allergies?
If nut allergies are a concern, you can easily substitute the pine nuts with sunflower seeds or pumpkin seeds, which provide a delightful crunch without the risk. For additional creaminess, opt for nutritional yeast instead of Parmesan cheese for a delicious vegan pesto that everyone can enjoy.
