Costco bulk bins hold everything you need for this restaurant-worthy autumn grain salad.

Costco’s bulk section is your best friend for this salad. Farro or quinoa from the grains aisle (look for organic or stone-ground varieties) forms the hearty base—both work equally well, though farro has a nuttier flavor. For the butternut squash, Costco’s pre-cut squash or their seasonal bulk squash cubes save time, though fresh is ideal if you’re prepping ahead. The pecans? Costco’s bulk pecans are unbeatable for price and quality—just toast them yourself for maximum flavor. If you’re short on time, their pre-shredded rotisserie chicken (seasoned with just salt and pepper) keeps perfectly for days, making this salad effortless for weeknight prep.

No butternut squash? Sweet potatoes or acorn squash work in a pinch, though the flavor will differ slightly. Swapping farro for quinoa? Use the same ratio—both grains cook to roughly the same volume. For the dressing, substitute balsamic vinegar for apple cider vinegar if needed, though the tartness will be slightly different. Fresh thyme unavailable? Dried thyme at one-third the amount works, but fresh is ideal for that bright herbal note. The pecans can be walnuts or almonds if you prefer—just toast them thoroughly for the same crunch. And if you’re making this ahead, store the dressing separately to keep the salad crisp.

This salad tastes even better the next day as flavors meld. Store components separately in airtight containers for up to 4 days—grains, roasted squash, and protein in one container, dressing in a small jar. Assemble just before serving to maintain crunch. For larger gatherings, double the dressing recipe—it keeps for 1 week in the fridge. The toasted pecans and dried cranberries can be prepped a week ahead and stored in a sealed container, while the apple slices should be added fresh for optimal texture. Freeze the grains and squash mixture (without dressing) for up to 3 months for a quick assembly later.

Step-by-step instructions for autumn grain salad with Costco ingredients

This warm, spiced grain salad delivers autumnal comfort in every bite—crispy nuts, tender squash, and bright apple crunch.

Preheat your oven to 400°F and line two baking sheets with parchment paper. In a large skillet over medium heat, toast the 1.5 cups pecans for 5-7 minutes, stirring constantly until they're golden brown and fragrant. Watch closely—they burn quickly. Immediately transfer the toasted pecans to a bowl and set aside.

While the pecans toast, toss the 3 cups cubed butternut squash with 1 tablespoon extra-virgin olive oil, 0.5 teaspoon salt, 0.25 teaspoon cayenne pepper, and 0.25 teaspoon cinnamon. Spread them in a single layer on the second baking sheet. Roast for 25-30 minutes until the edges are deep golden brown and the squash yields slightly when pierced with a fork. Remove from the oven and let cool for 5 minutes before combining with other ingredients.

Rinse the 2 cups farro or quinoa thoroughly under cold water until the water runs clear—this removes excess starch that can make the grains gummy. In a medium saucepan, combine the rinsed grains with 4 cups water (or the amount specified on your package), 0.75 teaspoon salt, and a pinch of black pepper. Bring to a boil, then reduce heat to medium-low and simmer for 25-30 minutes (or according to package instructions) until the grains are al dente—they should have a slight bite in the center.

Drain any remaining water through a fine-mesh strainer, then transfer the cooked grains to a large mixing bowl. While still warm, drizzle with 1 tablespoon extra-virgin olive oil and toss gently to coat. This step prevents the grains from drying out later when combined with other ingredients. Let the grains cool to room temperature before assembling the salad.

In a small bowl, whisk together the 0.5 cup extra-virgin olive oil, 0.25 cup maple syrup, 1.5 tablespoons Dijon mustard, 1.5 tablespoons apple cider vinegar, 0.25 cup finely chopped fresh thyme leaves, 0.5 teaspoon cinnamon, 0.5 teaspoon ground black pepper, and the remaining 0.75 teaspoon salt. Taste and adjust seasoning—you want a balance of sweet, tangy, and slightly spicy. The dressing should coat the back of a spoon but remain pourable.

In the same large bowl with the cooled grains, add the roasted butternut squash, toasted pecans, 2 cups apple slices, 2 cups shredded rotisserie chicken, and 0.75 cup dried cranberries. Pour the dressing over everything and toss gently but thoroughly with tongs or a large spoon. The salad should be evenly coated but still retain its individual textures—crisp pecans, tender squash, and juicy apple slices.

Cover the salad bowl and let it rest at room temperature for at least 30 minutes before serving. This resting period allows the flavors to meld together—you'll notice the pecans soften slightly, the dressing absorbs into the grains, and the spices infuse more deeply. If you're short on time, you can serve it immediately, but the flavor will be even better after resting.

Serve the salad chilled or at room temperature, garnished with an extra sprinkle of chopped fresh thyme leaves and a final drizzle of maple syrup if you prefer more sweetness. The contrast of warm spices, crisp nuts, and cool chicken creates a satisfying autumnal dish that's perfect for meal prep or a hearty lunch. Store leftovers in an airtight container in the refrigerator for up to 4 days, though I doubt it'll last that long!

Wine and beer pairings for autumn grain salad costco

Crisp White Wine

For this autumnal salad, I reach for a dry Riesling from Germany or a Sauvignon Blanc from New Zealand—both wines have bright acidity that cuts through the richness of the pecans and maple dressing while complementing the apple’s tartness.

A chilled glass (around 45°F) enhances the salad’s crisp textures. If you prefer something lighter, a Pinot Grigio from Italy offers a neutral backdrop that lets the spices shine. 🍷

Honey-Spiced Beer

A Belgian-style witbier like Hoegaarden or Stella Artois pairs beautifully with the salad’s sweet and spicy notes. The citrusy coriander and light effervescence balance the maple syrup and cinnamon, while the subtle sweetness mirrors the dried cranberries.

For a bolder option, try a honey ale—like Allagash Honey Beer—which echoes the maple and pecan flavors. Serve slightly chilled (40°F) to preserve the beer’s crispness. 🍺

Bold Red Wine

If you prefer red, a light-bodied Pinot Noir from Oregon or a Gamay from Beaujolais offers enough fruitiness to stand up to the salad’s spices without overpowering it. The wine’s earthy notes harmonize with the roasted squash and thyme, while its acidity keeps the dish feeling fresh.

Avoid heavy Cabernets—they’ll clash with the delicate apple and cranberry flavors. Decant for 15-20 minutes to soften tannins and enhance aroma. 🍇

Non-Alcoholic Options

For a refreshing non-alcoholic match, try sparkling apple cider—its effervescence and tartness mirror the salad’s bright flavors. Add a cinnamon stick for garnish to tie into the dish’s spiced profile.

Another great choice is ginger beer (like Feather Ginger Beer), which adds a zesty kick that complements the cayenne and thyme. Serve both chilled (38°F) for the best experience. 🍏
