This is a pasta salad built around roasted sweet potatoes, quinoa fusilli, and a limeโtahini dressing, with baby greens, pepitas, and cilantro rounding it out. It works as a complete meal because the quinoa pasta and sweet potatoes together give you real staying power โ not just roughage. It holds up well for packed lunches and actually tastes better after an hour in the fridge.
Before you start
Two things determine whether this salad succeeds. First, give the sweet potatoes room on the baking sheet โ crowding them causes steaming instead of caramelizing, and you lose the slightly crisp edges that add texture contrast against the soft pasta. A single tight layer on a rimmed sheet at 425ยฐF is non-negotiable. Second, the tahini dressing needs to be whisked with warm water gradually; tahini seizes up when liquid hits it all at once, and youโll end up with a lumpy paste instead of a pourable dressing. Add the warm water a tablespoon at a time until it loosens to a consistency that coats a spoon โ dress it at the table if youโre serving a crowd, because a pre-dressed salad sitting in a bowl for an hour will soak the greens into mush.
Common problems and fixes
- Pasta clumps after draining: Quinoa pasta sticks together more than wheat pasta as it cools. Toss it with a small drizzle of olive oil immediately after draining and spread it on a sheet pan for a few minutes to cool without clumping.
- Dressing tastes flat or one-dimensional: Tahini varies a lot by brand โ some are bitter, some are mild. Taste the dressing before tossing. If it tastes dull, a pinch more salt and an extra squeeze of lime usually fixes it. If it tastes bitter, a little more maple syrup balances it out.
- Pepitas lose their crunch: Toast them in a dry skillet just before assembling, not ahead of time. Stored toasted pepitas go soft within a day, especially once they hit the dressing. If making this ahead, keep them separate and add right before serving.
- Salad feels dry after refrigerating: The pasta absorbs dressing as it sits. Reserve a few tablespoons of dressing on the side and stir it in when you pull the salad out of the fridge. A splash of lime juice also wakes it back up.
- Red onion overwhelms everything else: The recipe suggests soaking sliced onion in cold water for five minutes, but if your onion is particularly sharp, extend that soak to ten minutes and change the water once. Drain thoroughly before adding โ excess water dilutes the dressing.
Roasted Sweet Potato & Quinoa Pasta Salad
Equipment
- Rimmed baking sheet
- Parchment paper
- Large pot
- Colander
- Large mixing bowl
- Small mixing bowl
- Whisk
- Skillet (dry) for toasting
- Tongs or spatula
- Microplane or fine grater
Ingredients
Roasted Sweet Potatoes
- 1 ยฝ lb sweet potatoes peeled and cut into 1/2-inch cubes
- 2 tbsp extra-virgin olive oil for roasting
- 1 tsp smoked paprika
- 1 tsp ground cumin
- 1 tsp kosher salt
- ยฝ tsp freshly ground black pepper
Pasta
- 1 tbsp kosher salt for the pasta water
- 12 oz quinoa fusilli pasta dry
Pepitas
- โ cup raw pepitas (pumpkin seeds)
LimeโTahini Dressing
- ยผ cup tahini well-stirred
- 3 tbsp fresh lime juice from about 2 limes
- 2 tbsp extra-virgin olive oil
- 1 ยฝ tbsp pure maple syrup
- 1 tsp Dijon mustard
- 1 tbsp apple cider vinegar optional, for extra brightness
- 1 clove garlic small, finely grated
- 3 tbsp warm water plus more as needed to loosen
- ยพ tsp fine sea salt
- ยผ tsp freshly ground black pepper
To Assemble
- ยฝ cup red onion, thinly sliced soak in cold water 5 minutes to mellow, then drain (optional)
- 3 cup baby kale or arugula loosely packed
- ยผ cup fresh cilantro, chopped
- ยฝ cup feta cheese, crumbled optional
- 1 tsp lime zest finely grated
Instructions
- Preheat and Prep: Position a rack in the center of the oven and preheat to 425ยฐF / 220ยฐC. Line a rimmed baking sheet with parchment for easy cleanup.
- Roast the Sweet Potatoes: Toss the cubed sweet potatoes with 2 tbsp olive oil, smoked paprika, cumin, 1 tsp kosher salt, and 1/2 tsp black pepper on the prepared sheet. Spread in a single layer. Roast at 425ยฐF / 220ยฐC for 22โ25 minutes, flipping once at the halfway point, until edges are caramelized and centers are tender.
- Cook the Quinoa Pasta: Bring a large pot of water to a rolling boil; add 1 tbsp kosher salt. Add the quinoa fusilli and cook 8โ10 minutes until al dente (check 1 minute early). Drain in a colander, rinse briefly under cool water to stop cooking, and shake off excess water. Toss with a splash of olive oil if desired and let cool to just warm.
- Toast the Pepitas: While the potatoes roast, warm a dry skillet over medium heat. Add pepitas and toast, stirring, 3โ4 minutes until they smell nutty and start to pop and turn golden. Transfer to a plate to cool.
- Make the LimeโTahini Dressing: In a small bowl, whisk the tahini, lime juice, olive oil, maple syrup, Dijon, and apple cider vinegar. Add the grated garlic, sea salt, and pepper. Whisk while drizzling in 3 tbsp warm water until smooth, glossy, and pourableโabout 1โ2 minutes. Adjust with more warm water a teaspoon at a time if needed; the dressing should ribbon off the whisk.
- Combine the Salad: In a large mixing bowl, add the cooled quinoa pasta, roasted sweet potatoes, red onion, baby kale (or arugula), and cilantro. Sprinkle in half of the toasted pepitas and the feta (if using). Drizzle over about two-thirds of the dressing and toss gently with tongs until evenly coated. Let the salad rest 5 minutes to slightly soften the greens and marry flavors.
- Finish and Serve: Taste and add more dressing as desired. Scatter the remaining pepitas and the lime zest over the top. Season to taste with additional salt, pepper, or a squeeze of lime. Serve slightly warm or at cool room temperature.
- Make-Ahead and Storage: For best texture, store dressed salad up to 2 days refrigerated; it will continue to absorb dressing. If making ahead 1 day, hold back the greens and pepitas and fold them in just before serving.
Notes
Chefโs Tips
- Cut sweet potatoes to an even 1/2-inch so they roast uniformly and finish at the same time.
- Rinsing quinoa pasta briefly stops carryover cooking and prevents gumminessโshake the colander well so the dressing isnโt diluted.
- Tahini varies in thickness; warm water loosens and helps the sauce emulsify. Add it gradually until the dressing ribbons smoothly.
- For vegan: omit feta or swap in a vegan feta. For nutty depth, add 2 tbsp toasted sesame seeds with the pepitas.
- Flavor swaps: replace smoked paprika with ancho chili powder for gentle heat, or add 1/2 tsp ground coriander to echo the cilantro.
- Protein boost: fold in 1 cup cooked black beans or shredded rotisserie chicken (not vegan) to make it a heartier main.
- Travel tip: pack extra dressing in a small jar and add just before eating to keep greens crisp.

Your questions, answered
Can I use a different pasta if I donโt have quinoa fusilli?
Yes โ any short pasta with ridges or curves works here. Chickpea rotini or lentil penne are good swaps that keep the dish gluten-free and maintain a similar protein level; regular wheat fusilli works too if gluten isnโt a concern.
How do I store leftovers, and how long do they keep?
Store the assembled salad in an airtight container in the fridge for up to three days. Keep the pepitas and any extra dressing separate so the seeds stay crunchy and you can loosen the pasta when you reheat or re-dress it.
Is this filling enough as a standalone meal, or does it need a side?
Itโs a complete meal on its own โ one serving comes in at 524 calories with protein from the quinoa pasta, sweet potatoes, and pepitas. If you want more protein, crumbled feta is already an option in the recipe, or you could add a soft-boiled egg on the side without changing the dish.
Can I roast the sweet potatoes ahead of time?
Yes, roast them up to two days ahead and refrigerate them in a sealed container. Let them come to room temperature before assembling โ cold straight-from-the-fridge potatoes make the dressing seize slightly and the salad ends up unevenly seasoned.
