The Costco bulk bins are your best friend for this recipe. Grab farro or wild rice from the grains section—both work, but farro has a nuttier bite. For the pecans, the Costco Kirkland brand is unbeatable value, and they’re already toasted, saving you time. Butternut squash? The pre-cut versions at Costco are a game-changer—they’re cheaper than organic at regular stores and just as sweet. If you’re roasting your own, look for smaller pieces (1-inch cubes) so they cook evenly. The pomegranate seeds can be tricky to find fresh, but Costco’s organic section usually has them in season. Pro tip: Toast your pecans in the same pan you roast the squash—they’ll soak up those warm, spiced flavors.
No farro? Wild rice or quinoa work just as well—just adjust cooking times. Running low on pecans? Walnuts or almonds add a different crunch, but toast them extra long to compensate. The Dijon mustard is non-negotiable here—Maille is the gold standard, but Costco’s Kirkland is a solid budget pick. Swapping maple syrup? Agave or date syrup keeps things vegan, but honey adds a deeper caramel note if you’re not avoiding it. The celery crowns are the star of the texture game—if you can’t find them, regular celery ribs (the thick stems) work, but they’ll be less dramatic. Fresh thyme? Dried works at half the amount, but it won’t have that bright, herbal punch.
This salad tastes even better the next day—make a double batch and store it in airtight containers. The grains stay hearty for 4-5 days in the fridge, and the dressing keeps for 1 week if separated. Roast the squash and toast the nuts ahead—they’re the most time-consuming steps, and doing them early lets you assemble the salad in minutes. For meal prep, portion the dressing separately and toss it in just before serving so the greens stay crisp. Freezing? The grains and nuts hold up for 3 months, but the squash gets mushy—best to skip freezing that part.

- Costco’s Pre-Cut Magic: Between us, the celery crowns and pre-roasted butternut squash from Costco mean I’m only chopping pecans and toasting farro—no peeling, dicing, or waiting for a roasting pan to clear. Honestly, I’ve made this salad on a Friday night while scrolling through my phone; the hardest part is deciding whether to eat it immediately or wait for leftovers.

Step-by-step instructions for autumn grain salad with warm spiced nuts
This salad is all about texture contrast—crispy roasted celery crowns, tender farro, and crunchy spiced pecans.
🔥 Step 1: Roast the Butternut Squash and Celery Crowns
Preheat your oven to 425°F and line two baking sheets with parchment paper. Toss the 3 cups of butternut squash and 2 whole celery crowns (cut into 1-inch pieces) with 2 tablespoons of the extra-virgin olive oil, 1 teaspoon of salt, and 0.25 teaspoon of black pepper. Spread them in a single layer—they need room to crisp.
Roast for 25-30 minutes until the squash is tender when pierced with a fork and the celery crowns are crispy and golden brown. Here's the thing—don't walk away! Check at 20 minutes because ovens vary. The celery should be caramelized but still hold its shape.
🍳 Step 2: Cook the Farro or Wild Rice
While the vegetables roast, rinse the 2 cups of farro or wild rice under cold water to remove excess starch. In a medium saucepan, combine the rinsed grains with 4 cups of water (or follow package instructions if using wild rice) and bring to a boil. Reduce heat to medium-low and simmer for 25-30 minutes until the grains are tender and the liquid is absorbed.
Drain any remaining water and transfer the cooked grains to a large bowl. While still warm, stir in 1 tablespoon of fresh thyme leaves, 2 tablespoons of lemon juice, and 1 tablespoon of Dijon mustard. This gives the farro a bright, herby kick that balances the sweetness of the roasted vegetables.
🔥 Step 3: Toast and Spice the Pecans
In a dry skillet over medium heat, toast the 1 cup of pecans for 3-4 minutes until fragrant and lightly golden. Watch them like a hawk—they burn fast! Remove from heat and immediately transfer to a bowl. Add 0.5 teaspoon of ground cinnamon, 0.25 teaspoon of ground nutmeg, 1 teaspoon of salt, and 2 tablespoons of pure maple syrup.
Toss the warm pecans with the spices and syrup until evenly coated. Let them cool for 5 minutes while you finish the salad. The syrup will thicken slightly as it cools, giving the pecans a sticky, caramelized finish that's irresistible.
🥘 Step 4: Assemble the Salad with Crunchy Textures
In a large serving bowl, combine the warm farro, roasted butternut squash, and crispy celery crowns. Drizzle with the remaining 3 tablespoons of extra-virgin olive oil and toss gently to distribute. The residual heat from the farro will help the oil cling beautifully.
Scatter the spiced pecans and 0.5 cup of pomegranate seeds over the top. Here's where it gets exciting—taste and adjust seasoning. You might need a pinch more salt or a squeeze of lemon to balance the sweetness of the pecans and squash. Serve immediately while everything is warm and crisp!
Pro Tips For Making Autumn Grain Salad Costco
- TOAST THE PECANS: Throw those pecans in a dry skillet over medium heat for 3-4 minutes until they’re golden and smell like autumn. I learned this the hard way—raw pecans taste bland and mealy in this salad, while toasted ones add that perfect crunch and nutty depth. (Yes, even if you're impatient like me, resist the urge to rush.)
- ROAST SQUASH UNTIL TENDER: Cube the butternut squash into even 1-inch pieces and roast at 400°F for 25-30 minutes, stirring once. I used to undercook it, thinking it’d soften later—wrong. You want it fork-tender so it blends into the salad without tasting raw. Toss with olive oil and salt before roasting; that’s the thing that matters most.
- SHRED CELERY FINE: Skip the thick slices—slice the celery crowns lengthwise, then chop into paper-thin matchsticks. Thick celery stays crunchy and overwhelming in this dish. My grandmother swore by this, and she was right: it distributes flavor evenly and keeps the texture light.
- DRESS GRAINS COOL: Let the farro or wild rice cool completely before tossing with dressing—about 15 minutes off the heat. Hot grains absorb too much liquid and turn mushy. I was skeptical until I tried it; the salad stays bright and the grains hold their shape. (Your future self will thank you.)
