Ingredients for 5 grain salad

Five grains, vibrant veggies, and a tangy dressing—this salad packs energy for all-day picnics.

The grains are the heart of this dish, so don't skimp. Bob's Red Mill has great bulk bins for farro and quinoa—just make sure they're labeled 100% whole grain. Wild rice can be pricey, but Costco sells it in bulk for a steal. Cook each grain separately for perfect texture: farro and barley should be chewy, quinoa fluffy, and brown rice firm. Pro tip: Toast the grains in olive oil for 2 minutes before adding liquid—this deepens their nutty flavor. If you're short on time, use pre-cooked grains from the canning aisle, but rinse them well to cut down on sodium.

No cucumber? Zucchini or radishes work in a pinch, but cucumber's crispness is key. The bell pepper can be any color—red, yellow, or orange all add their own sweetness. Red onion adds bite, but if you're sensitive to raw onions, soak chopped pieces in cold water for 10 minutes to mellow the flavor. For the dressing, I like to make it just before tossing—Dijon mustard gives it that little extra tang. No Dijon? Yellow mustard at half the amount works too. The optional chickpeas are a game-changer for protein—Trader Joe's has canned ones that are perfect for this.

Grains keep best in the fridge for 4-5 days in an airtight container. The dressing separates if stored separately, so mix it right before serving. For meal prep, I portion the grains and veggies separately, then toss with dressing when ready to eat. The salad tastes even better the next day as flavors meld. If you're taking it to a picnic, pack the dressing separately and mix just before serving—keeps everything crisp. Double the batch and freeze half for up to 3 months—perfect for busy weeks.

Step-by-step instructions for 5 grain salad

Here's how to create a perfectly balanced, nutty, and crunchy 5-grain salad that's perfect for picnics.

Start by rinsing the 1 cup farro and 1 cup quinoa thoroughly under cold water to remove any bitterness. In a medium saucepan, combine the rinsed farro with 4 cups vegetable broth and bring to a boil. Once boiling, reduce heat to low, cover, and simmer for 25-30 minutes until tender but still slightly chewy. Drain any excess liquid and set aside.

In another saucepan, cook the 0.5 cup barley and 0.5 cup wild rice blend separately according to package instructions—barley typically takes 45-50 minutes, while wild rice needs 40-45 minutes. The 0.5 cup brown rice should be cooked in a separate pot with fresh broth for 35-40 minutes. This separate cooking ensures each grain maintains its distinct texture in the final salad.

While the grains cook, dice the 1.5 cups cucumber into ½-inch cubes and halve the 1 cup cherry tomatoes, removing seeds for cleaner bites. Finely chop the 0.5 cup red onion and 0.5 cup red bell pepper into small, even pieces—this ensures even distribution in the salad. If using the 1 cup optional chickpeas, rinse and drain them thoroughly to remove any canned liquid.

Chop the 0.25 cup fresh parsley finely and toast the 0.5 cup almonds in a dry skillet over medium heat for 3-4 minutes until fragrant and golden. Let them cool completely before adding to the salad—they'll add a wonderful crunch that contrasts beautifully with the soft grains.

In a small bowl, whisk together the 0.25 cup extra-virgin olive oil, 2 tbsp lemon juice, and 1 tbsp Dijon mustard until fully combined. Gradually add 1.5 tsp salt and 0.5 tsp black pepper, whisking constantly until the dressing is smooth and emulsified. Taste and adjust seasoning—you want it tangy but balanced, with just enough salt to enhance all the flavors.

Here's the thing—this dressing should coat the back of a spoon but not be overly thick. If it's too thick, add 1-2 teaspoons of water to loosen it. The dressing ties all the components together, so don't skip this step!

In a large mixing bowl, gently combine the cooled grains with the prepared vegetables and toasted almonds. Add the chickpeas if using, and sprinkle the chopped parsley over the top. Pour the dressing over the mixture and toss everything together with a large spoon or your hands, being careful not to mash the grains.

Let the salad sit for 10-15 minutes before serving—this allows the flavors to meld together. The grains will absorb some of the dressing, and the vegetables will soften slightly, creating a perfect balance of textures. If the salad seems dry after resting, add a splash more dressing.

Transfer the salad to an airtight container and refrigerate for at least 1 hour before serving. Chilling allows all the flavors to develop fully and makes each bite even more satisfying. When ready to serve, give it one final toss to distribute everything evenly.

This salad keeps well in the fridge for 3-4 days, making it perfect for meal prep. The grains stay hearty, the vegetables retain their crispness, and the dressing keeps the whole thing vibrant. Serve it at room temperature for the best texture contrast!

Picnic Platter Pairings

This salad is a picnic powerhouse—pair it with crusty baguette slices for scooping up every last bite. I love adding whipped feta cheese with a drizzle of honey and cracked black pepper for a sweet-savory contrast.

For a complete spread, include charcuterie-style cured meats like prosciutto or salami on the side. 🧀

Protein Add-Ons

Boost the salad's protein with grilled chicken breast or smoked salmon> slices. For a vegetarian option, add crumbled goat cheese> or marinated white beans. I often include hard-boiled eggs> halved and sprinkled with smoked paprika for extra richness. The grains hold up beautifully with these additions.
