Roasted Garlic Parmesan Pasta Salad with Green Beans
A vibrant cold pasta salad built on roasted garlic oil and sharp Parmesan cheese, studded with tender roasted green beans and fresh herbs. The garlic cloves become sweet and creamy when roasted, infusing the dressing with mellow richness. Toss it together warm so the pasta absorbs the flavors, then chill before serving for a perfect summer side or light lunch.

Steps
Before you start
- Preheat your oven to 400°F (200°C)
- Bring a large pot of salted water to a boil for the pasta
- Have all ingredients prepped and ready before roasting begins
Roast the garlicOven 400°F / 205°C
- Place the cut garlic bulbs on a small baking sheet, cut-side up.
- Drizzle with 2 tablespoons (30 ml) of the olive oil, scatter the thyme sprigs around them, and season with a pinch of salt and pepper.
- Cover tightly with foil and roast at 400°F (200°C) until the cloves are golden, very soft, and easily squeeze out of their skins, about 35 minutes.
- The garlic should smell deeply savory and nutty.
- Remove from oven and let cool for 5 minutes.

Ready when: Garlic cloves are golden and squeeze easily from their skins
Tip: Cover with foil so the garlic steams gently rather than browning too quickly on top
Cook pasta and green beans
- While the garlic roasts, bring a large pot of salted water to a boil.
- Add the pasta and cook according to package directions, but reduce the cooking time by 1 minute—you want it just slightly al dente since it will continue to soften as it cools.
- About 2 minutes before the pasta is done, add the trimmed green beans to the same pot.
- Cook until the beans are tender-crisp (about 2 minutes).
- Drain pasta and beans in a colander, but do not rinse.

Ready when: Pasta is just under al dente and green beans are bright green and tender-crisp
Tip: Don't rinse the pasta—the starch helps the dressing coat it better and lets it absorb more flavor
Squeeze and mash the roasted garlic
- Once the roasted garlic is cool enough to handle, gently squeeze the soft roasted cloves out of their papery skins into a small bowl.
- You should have roughly 3 tablespoons (45 ml) of paste.
- Mash the cloves with the back of a spoon until they form a smooth, creamy paste.

Ready when: Garlic is mashed into a smooth, creamy paste
Tip: Work gently so you don't lose any of the precious roasted cloves—they're the heart of this salad
Make the dressing
- In a small bowl, whisk together the roasted garlic paste, remaining 2 tablespoons (30 ml) of olive oil, and red wine vinegar.
- Season generously with salt and freshly ground black pepper.
- Taste and adjust the acidity and seasoning as needed—the dressing should taste rich, garlicky, and balanced between savory and slightly tangy.

Ready when: Dressing is smooth, well-emulsified, and tastes balanced
Tip: Taste as you go—roasted garlic sweetness varies, so you may need slightly more or less vinegar
Assemble the salad
- Transfer the warm pasta and green beans to a large mixing bowl.
- Pour the roasted garlic dressing over them and toss gently but thoroughly, making sure every strand of pasta is coated.
- The warm pasta will absorb the dressing flavors.
- Add the grated Parmigiano-Reggiano and fresh parsley, and toss again gently.
- Season with additional salt and pepper to taste.

Ready when: All ingredients are evenly coated with dressing and cheese is distributed throughout
Tip: Toss gently to avoid breaking the green beans, but make sure the dressing coats everything evenly
Chill and finish
- Transfer the salad to a serving bowl or cover and refrigerate for at least 30 minutes (up to 4 hours) to let the flavors meld and the salad to chill through.
- Just before serving, taste again and adjust the seasoning if needed.
- If the salad seems dry after chilling, drizzle with a little more olive oil.
- Top with lemon zest if using, and serve cold or at room temperature.

Tip: Cold pasta salads always benefit from seasoning after chilling, since cold temperatures mute flavors
Good to know
Tips
- For the best flavor and texture, roast the garlic the day before so it has time to cool completely and develop deep, mellow flavors that won't overpower the salad.
- Never rinse the cooked pasta—the starch coating helps the warm pasta absorb the dressing and creates a cohesive, flavorful salad rather than a dry, separated one.
- If you can't find good fresh Parmigiano-Reggiano, the salad won't be as good. Pre-shredded varieties contain cellulose and won't melt into the warm pasta the way freshly grated cheese does.
- This salad tastes best served at room temperature rather than ice-cold straight from the fridge, as the flavors are more vibrant and the pasta texture is better.
Make ahead
You can roast the garlic up to 2 days ahead and store it in an airtight container in the fridge. Make the dressing up to 1 day ahead. Assemble the salad no more than 4 hours before serving so the pasta doesn't become mushy; if made ahead, store covered in the refrigerator and add a splash of olive oil before serving if needed.
Storage & reheating
Room temperature: up to 2 hours (though flavors are best served freshly made). Refrigerator: covered, up to 3 days. Freezing is not recommended, as the pasta becomes mushy. To reheat, bring to room temperature and refresh with a light drizzle of olive oil and a squeeze of fresh lemon juice.
Substitutions
- fresh green beans, trimmed → blanched and halved fresh asparagus, or roasted zucchini cut into bite-sized pieces. Both vegetables roast beautifully and pair well with roasted garlic and Parmesan
- Parmigiano-Reggiano cheese, finely grated → aged Pecorino Romano, finely grated. Use the same amount; it's saltier and more peppery than Parmigiano-Reggiano, so taste carefully
- red wine vinegar → sherry vinegar or white wine vinegar. Use the same amount for a slightly milder, more delicate acidity
- pasta (rotini, penne, or fusilli) → whole-wheat or chickpea pasta for added protein and fiber. Check package directions for cooking time, as these often take longer than refined pasta
