Let me tell you about the first time I truly fell in love with Trenette al Pesto.

And the best part? You can recreate this culinary masterpiece in under 30 minutes, turning your ordinary weeknight into a Ligurian holiday.

The Story Behind the Sauce
Pesto isn’t just a condiment in Liguria – it’s a way of life. The Genoese have been perfecting this emerald elixir since the Middle Ages, originally made by sailors who needed flavorful provisions that wouldn’t spoil. There’s something almost sacred about the traditional mortar and pestle method – the rhythmic grinding releases the basil’s soul in a way no machine can replicate.
Essential Ingredients & Tools
For the Pesto (Your Flavor Bomb)
- 2 cups (50g) fresh basil leaves – Seek out Genovese basil if you can (standard sweet basil works too); its sweeter, more delicate flavor is worth the hunt
- 3 tbsp (25g) pine nuts – Toast them until they smell like heaven and turn the color of a summer tan (walnuts or almonds make fine substitutes)
- 2 small garlic cloves – Because every great love story needs a little spice
- ½ tsp fine sea salt – The conductor of this flavor orchestra
- ½ cup (120ml) extra virgin olive oil – The liquid gold that brings it all together (use a mild, fruity variety)
- ⅓ cup (25g) Pecorino Romano – For that salty kick (Parmesan alone works if needed)
- ½ cup (50g) Parmigiano Reggiano – The nutty, umami-rich counterpart
For the Pasta & Veggies
- 14 oz (400g) trenette pasta – Those long, flat ribbons are perfect sauce catchers (linguine or fettuccine work in a pinch)
- 1 cup (150g) green beans – Trimmed and cut into happy little batons
- 1 cup (150g) small potatoes – Peeled and cubed into bite-sized nuggets of comfort
Tools You’ll Need
- Large pot – For the pasta party
- Mortar and pestle – The traditionalist’s choice (a food processor or even a blender works too)
- Small skillet – For toasting those pine nuts to perfection
- Colander – Your pasta’s exit strategy
- Large mixing bowl – Pre-warmed like a cozy blanket for your noodles

How to Make Trenette al Pesto
- Awaken the Pine Nuts
In a dry skillet over medium-low heat, toast your 3 tbsp (25g) pine nuts like you’re warming them for a spa day. Shake the pan like you’re playing maracas – we want golden perfection, not charcoal. When they smell like the best thing you’ve ever smelled (about 3-4 minutes), evacuate them to a plate. They’ll keep cooking if you leave them in the hot pan – trust me, I’ve learned this the hard way. - Pot of Gold
Bring a large pot of water to a rolling boil – salt it like the Mediterranean sea (about 2 tbsp per gallon). Add 1 cup (150g) potatoes first (they’re the slowpokes of the veggie world). After 4 minutes, add 1 cup (150g) green beans – we want everything to finish cooking together like a well-rehearsed orchestra. - Mortar & Pestle Magic
Here’s where the romance happens. Crush 2 small garlic cloves and ½ tsp fine sea salt into submission until it’s a smooth paste (this prevents harsh garlic bites). Add your cooled 3 tbsp (25g) pine nuts and grind them into a coarse rubble. Now the 2 cups (50g) basil – don’t massacre it, bruise it lovingly with clockwise circular motions (this preserves the vibrant color). Imagine you’re a painter mixing the most important color of your life. Slowly drizzle in ½ cup (120ml) extra virgin olive oil like you’re adding the final strokes to your masterpiece. Finally, stir in ⅓ cup (25g) Pecorino Romano and ½ cup (50g) Parmigiano Reggiano by hand – this keeps them from getting gummy. - Food Processor Shortcut
If you’re going the modern route, pulse 2 small garlic cloves, ½ tsp fine sea salt, and 3 tbsp (25g) nuts first. Add 2 cups (50g) basil in batches – we’re making pesto, not basil soup (pulse 5-6 times per batch to avoid overheating). With the motor running, stream in ½ cup (120ml) extra virgin olive oil like you’re feeding a hungry baby bird. Transfer to a bowl and stir in ⅓ cup (25g) Pecorino Romano and ½ cup (50g) Parmigiano Reggiano by hand – this step is non-negotiable for texture. - Pasta Time
Add your 14 oz (400g) trenette to the boiling water with the veggies. Cook until al dente (8-10 minutes) – it should have the resistance of a good handshake. Before draining, reserve ½ cup (120ml) of that starchy pasta water – it’s the secret handshake of great pasta dishes. - The Grand Finale
Drain everything and toss it into a pre-warmed bowl (cold bowls are the enemy of hot pasta). Add your pesto and toss like you’re mixing a salad for the queen. Add reserved ½ cup (120ml) pasta water a tablespoon at a time until the sauce clings to the noodles like a silk dress (the starch helps emulsify the sauce). - Serve with Love
Plate it up with extra Parmigiano and a final drizzle of olive oil – the Italian equivalent of a mic drop. Serve in warmed bowls because temperature matters more than you think.
Pro Technique
Why Mortar Matters
That rhythmic grinding isn’t just for show – it crushes cell walls gently, releasing the basil’s essential oils without the bitterness that blades can cause. The friction also naturally emulsifies the oil and water in the basil. Think of it as a slow dance versus a mosh pit for your ingredients.
Starchy Water Sorcery
That reserved pasta water isn’t just liquid – it’s magic glue. The starch helps emulsify the sauce at 160°F/71°C, preventing your beautiful pesto from breaking up like a bad relationship. Add it hot to melt the cheese just enough for creaminess.
Chef’s Wisdom
Basil Betrayal
Over-processing basil in a food processor is like putting a fresh salad in a blender – tragic (it causes oxidation and browning). Pulse gently and consider chilling your bowl first. For mortar pesto, work in batches – overcrowding leads to uneven grinding and sad pesto.
Garlic Gone Wild
Raw garlic can be a bully in pesto. To tame it, blanch the cloves for 30 seconds or infuse your oil with garlic first (then cool it). If using a processor, scrape down the sides often – rogue garlic chunks are nobody’s friend.
Cheese Texture Tragedy
Always grate your cheese finely – big shreds will just clump together in disappointment. Let grated cheese sit at room temp for 10 minutes before using – it incorporates better. And for the love of pasta, avoid pre-grated cheese with anti-caking agents (they make sauce grainy).
Storage & Freshness Guide
Solo Pesto
Store in an airtight container with a layer of olive oil on top – it’s like a security blanket against oxidation. Fridge for 5 days or freeze in ice cube trays (then transfer to a bag) for up to 3 months.
Leftover Pasta
Reheat gently with a sprinkle of water, covered, in 30-second bursts. High heat will make the cheese sad and separated. Best eaten within 2 days.
Veggie Prep
Blanch your green beans and potatoes ahead, then shock them in ice water to stop cooking. They’ll keep in the fridge for 48 hours – just reheat briefly in pasta water before mixing with pesto.
Ingredient Variations and Their Impact
Nut Experiments
Out of pine nuts? Try walnuts for earthy depth or almonds for sweetness. For luxury, use Marcona almonds – they’re like the filet mignon of nuts.
Cheese Adventures
Swap Pecorino for aged Manchego if you’re feeling bold (reduce salt though). Vegan? A teaspoon of white miso paste adds incredible umami depth.
Green Thumb
Mix in arugula or parsley for a peppery twist. Stretching your basil? Add blanched spinach – it’s like a stealthy flavor extender.
Pasta Shapes
No trenette? Try trofie (Liguria’s classic pesto pasta) or orecchiette – their nooks are perfect sauce traps. Pro tip: Undercook pasta by 2 minutes and finish it in the pesto with pasta water for maximum flavor absorption.
Perfect Pairings
Complementary Dishes
- Grilled Shrimp: The smoky char contrasts beautifully with the fresh pesto. Marinate in lemon and garlic for 15 minutes before grilling.
- Caprese Salad: Sliced tomatoes and fresh mozzarella echo the basil-cheese harmony, adding a cool contrast.
Drinks
- Ligurian Vermentino: This local white wine’s crisp acidity cuts through the richness perfectly. Chill to 50°F (10°C).
- Sparkling Lemonade: The citrus effervescence cleanses the palate between bites for a non-alcoholic option.
Something Sweet
- Lemon Olive Oil Cake: Moist and citrusy, it complements without overpowering.
- Dark Chocolate-Dipped Figs: The honeyed sweetness balances the meal’s savory notes.
FAQs
- No mortar or processor?
Chop everything finely and whisk like your dinner depends on it – you’ll get a rustic but delicious result. - Why is my pesto brown?
Oxidation got it! Work quickly and press plastic wrap directly onto the pesto’s surface to keep it green. - Vegan options?
Skip the cheese or use vegan Parmesan. Nutritional yeast adds a nice umami punch. - Potatoes and green beans necessary?
For the authentic experience, absolutely! They add heartiness and texture that makes this dish special. - Sauce separated?
Toss your pasta hotter, add starchy water slowly, and emulsify like you mean it. It’ll come back together.
