A salad without lettuce? Absolutely — grains like quinoa make excellent salad bases. I often use quinoa in a variety of salads, and this roasted Thanksgiving salad ranks among my favorites. It brings together the warm, cozy flavors of the season in one bowl.

Imagine the essence of Thanksgiving — roasted root vegetables, aromatic herbs, crisp apples, and a bright, slightly sweet dressing — all tossed with quinoa. This recipe captures that idea perfectly. It’s inspired by a version I found in an Alton Brown cookbook, and after trying it once we kept making it again and again.

What makes this salad especially good is its versatility. It’s perfect alongside a holiday meal, but it also makes a fantastic make-ahead lunch. Because there are no leafy greens to wilt, the flavors develop in the fridge and the salad can be stored for several days.

Ingredient Notes

  • Veggies – Sweet potatoes add a gentle sweetness while parsnips lend a nutty, earthy flavor that suits fall dishes.
  • Apples – Crisp apples (Honeycrisp works well) add brightness and a pleasant contrast to the roasted vegetables.
  • Herbs – Fresh thyme, sage and rosemary give the salad that autumnal, Thanksgiving character.
  • Quinoa – A protein-packed grain that forms the hearty base of the salad.
  • Dressing – A simple mix of olive oil, apple cider vinegar, maple syrup and Dijon mustard balances tang, sweetness and depth.

Ingredient Swaps

Feel free to adapt the recipe based on what you have or prefer. Some easy swaps:

  • Substitute sweet potatoes with butternut squash or pumpkin for a similar texture and sweetness.
  • If you prefer, replace parsnips with carrots for a familiar root-vegetable flavor.
  • Any mild onion will work in place of red onion — white, yellow or shallots are fine.
  • If fresh herbs aren’t available, use dried herbs at about one-third the amount since they’re more concentrated.
  • Quinoa can be swapped for barley, couscous or rice if desired.

FAQs

Can I use another vegetable besides sweet potatoes?

Yes. Butternut squash or pumpkin are excellent alternatives and roast in roughly the same time as sweet potatoes.

Is this salad healthy?

Yes. It combines vegetables, fruit and quinoa for fiber, vitamins and plant protein. The dressing uses maple syrup sparingly for a lighter sweetness compared to many dressings.

Can I make it ahead of time?

Yes. Because there are no leafy greens, the salad stores well in the fridge for up to five days. It’s best served at room temperature or slightly warm—take it out of the fridge about an hour before serving.

Benefits of Quinoa

Quinoa is a nutritious, versatile grain. Key benefits include:

  • Contains all nine essential amino acids, making it a complete protein.
  • Higher in fiber than many grains, which supports digestion and blood-sugar control.
  • Provides iron and magnesium, important for energy and healthy blood vessels.
  • Offers vitamins and minerals like manganese and riboflavin that support metabolism and antioxidant defenses.

Pro Tips / Recipe Notes

  • Dice vegetables to a consistent size so they roast evenly. Smaller pieces cook faster; larger pieces take longer.
  • Swap vegetables freely — carrots, russet potatoes or other winter squash all work.
  • Shake the dressing in a jar to emulsify quickly and make cleanup easier.
  • Serve at room temperature or warm. If chilled, remove the salad from the refrigerator about one hour before serving so flavors open up.
