Ingredients for autumn grain salad costco

Costco staples and seasonal produce create this hearty autumn grain salad.

The grains are the foundation, so Costco's bulk farro and wild rice blend saves money and time—just rinse before cooking. Wild rice adds chewy texture, while farro brings nutty depth. For the chicken, Costco's rotisserie is a game-changer: shred it yourself for better texture than pre-shredded. Honeycrisp apples are non-negotiable—their crisp bite and natural sweetness balance the savory grains perfectly. If you can't find them, Fuji or Gala work in a pinch, but they won't caramelize as beautifully when roasted.

No rotisserie chicken? Poached or baked chicken breast works just as well—just shred it finely. Subbing pecans? Walnuts or candied pecans add crunch, though they lack the same buttery richness. For the dressing, maple syrup is key—don't skimp on quality. Grade B has more flavor than Grade A. The cinnamon and nutmeg in the vinaigrette might seem unusual, but they're essential for that autumnal warmth. If you're missing either, allspice or cardamom can bridge the gap, though the flavor won't be identical.

Cook the grains ahead and store them separately in the fridge for 3 days—they'll keep their texture better than if mixed with everything. The apples and pecans can be roasted up to 2 days ahead and stored in airtight containers. The vinaigrette keeps for 1 week in the fridge, so make extra for other salads. When ready to assemble, toss everything together gently—just before serving to keep the apples crisp. This salad tastes even better the next day as flavors meld, making it perfect for meal prep.

Step-by-step instructions for autumn grain salad

This seasonal salad brings together hearty grains, crisp apples, and smoky chicken for a balanced dish that shines at fall gatherings.

Rinse the 1 cup farro and ½ cup wild rice blend separately under cold water to remove excess starch. In a medium saucepan, combine both grains with 4 cups water and bring to a boil over high heat. Once boiling, reduce to a simmer and cook for 30-35 minutes until the farro is tender but still has a slight bite and the rice is plump. The grains should be cooked until all liquid is absorbed and they're fork-tender with minimal resistance.

Drain any remaining water and immediately spread the grains on a baking sheet to cool. This prevents them from becoming mushy. While they cool, I like to give them a gentle toss with a fork to separate any clumps—this ensures each bite has that satisfying texture contrast later in the salad.

Preheat your oven to 350°F and spread the 1 cup chopped pecans evenly on a rimmed baking sheet. Toast for 8-10 minutes until they're golden brown and fragrant. Watch them closely—they burn quickly once they reach that perfect color. Let them cool completely before adding to the salad, as warm pecans can make the dressing separate.

Here's the thing—properly toasted pecans add an entirely different dimension to this salad. They should be crisp with a rich, buttery aroma. If you're short on time, you can toast them in a dry skillet over medium heat for 5-6 minutes, stirring constantly, but oven toasting gives more even results.

Core and dice the 2 medium Honeycrisp apples into ¼-inch pieces. Toss them immediately with 1 teaspoon lemon juice to prevent browning—this keeps them vibrant and crisp in the salad. Thinly slice the ½ whole red onion and place in a bowl of ice water for 5 minutes to mellow their sharpness while you finish the other components.

The lemon juice is crucial here. Without it, the apples will oxidize quickly and turn dull brown, which ruins the visual appeal of this autumn salad. The ice water treatment for the onions is a pro trick—it softens their bite just enough to make them pleasant to eat without losing their texture entirely.

In a small saucepan, combine ½ cup extra-virgin olive oil, 3 tablespoons maple syrup, 1 tablespoon Dijon mustard, 2 tablespoons apple cider vinegar, 1½ teaspoons salt, ½ teaspoon black pepper, ¼ teaspoon cinnamon, and ⅛ teaspoon nutmeg. Whisk over low heat for 3-4 minutes until the mixture reaches 160°F—just warm enough to blend the flavors but not hot enough to cook the mustard.

This warm dressing technique creates a silky texture that coats every component beautifully. The spices should be fully dissolved and the mixture should have a glossy sheen. If it looks too thick, add 1-2 teaspoons water to reach a pourable consistency. Let it cool slightly before using—it'll thicken as it cools.

In a large bowl, combine the cooled grains, shredded rotisserie chicken, diced apples, drained onions, toasted pecans, and chopped parsley. Pour the warm dressing over everything and toss gently but thoroughly to coat all components evenly. Taste and adjust seasoning if needed—you might want to add a pinch more salt or a splash of vinegar to balance the sweetness.

Cover the salad and refrigerate for at least 1 hour before serving. This chilling time allows all the flavors to meld together beautifully. The apples will soften slightly, the grains will absorb some of the dressing, and the chicken will become perfectly integrated into the texture. Serve at room temperature for the best texture contrast between the warm dressing and cool components.

Wine and beer pairings for this autumn grain salad costco

Crisp White Wine

For this autumn grain salad, I reach for a dry Riesling or Pinot Grigio—both wines have bright acidity that cuts through the richness of the pecans and maple dressing while complementing the apple's natural sweetness.

A German Riesling like Dr. Loosen Blue Slate offers mineral notes that enhance the salad's earthy grains, while an Italian Pinot Grigio from Alto Adige provides crisp citrus flavors that refresh the palate. Serve slightly chilled for the best experience. 🍷

Spiced Red Blend

If you prefer red wine, opt for a light-bodied Pinot Noir or Gamay with subtle spice notes. Look for wines labeled "Beaujolais" or "Willamette Valley" Pinot Noir—they have enough fruitiness to balance the salad's maple and apple flavors without overpowering the delicate herbs.

A Crozes-Hermitage from the Rhône Valley adds a touch of earthiness that pairs beautifully with the farro and wild rice. 🍇

Autumn Ale Pairing

For beer lovers, a honey-brown ale or amber ale with caramel and nutty undertones is perfect. New Belgium's Fat Tire or Samuel Adams' Noble Pils both work well—their malty sweetness mirrors the maple dressing, while the hop bitterness provides balance.

If you prefer something lighter, a Belgian witbier like Stella Artois' Wit adds a peppery-spiced note that complements the salad's cinnamon and nutmeg. 🍺

Cider Alternative

Don't underestimate the power of hard cider for this dish. A dry, crisp cider like Angry Orchard Crisp Apple or Woodchuck Hard Cider mirrors the apple flavors in the salad while adding a refreshing acidity.

For a richer option, try a spiced cider like Magners Cider with Spices—the clove and cinnamon notes enhance the dressing's warm spices. Serve slightly chilled to highlight the cider's crispness. 🍎

Non-Alcoholic Options

For a mocktail pairing, blend sparkling apple cider with a splash of ginger beer and a cinnamon stick for garnish. The effervescence cleanses the palate between bites, while the ginger adds a subtle kick that complements the salad's autumnal warmth.

For a more sophisticated option, try sparkling water infused with blackberries and mint—the berry sweetness echoes the salad's apples while the mint refreshes the palate. ✨
