Sweet Potato Farro Salad with Tangy Lemon Herb Dressing

Sweet potato farro salad brings chewy pearled farro and caramelized roasted sweet potatoes together with peppery greens, dried cranberries, feta, and toasted pepitas. A lively lemon-herb dressing ties the sweet, savory, and tangy flavors together, making this a satisfying warm or room-temperature meal and a practical dish to prepare ahead.

Ingredients

1 cup (190 g) pearled farro, rinsed and drained
3 cups (710 ml) water, for cooking the farro
1/2 teaspoon (3 g) fine salt, for the cooking water
1 1/2 pounds (680 g) sweet potatoes, peeled or scrubbed and cut into 3/4-inch (2 cm) cubes
1 1/2 tablespoons (22 ml) olive oil, for roasting
1/2 teaspoon (1 g) ground cumin
1/4 teaspoon (0.5 g) black pepper, plus more to taste
1 small red onion (about 2 1/2 ounces/70 g), thinly sliced
3 cups (60 g) baby arugula, washed and dried
1/2 cup (60 g) dried cranberries
4 ounces (115 g) crumbled feta cheese
1/3 cup (40 g) raw pepitas (shelled pumpkin seeds)
3 tablespoons (45 ml) extra-virgin olive oil, for the dressing
3 tablespoons (45 ml) fresh lemon juice, from about 1 large lemon
1 tablespoon (15 ml) maple syrup
1 teaspoon (5 g) Dijon mustard
1 small garlic clove (about 3 g), finely grated or minced
1/4 cup (15 g) chopped fresh flat-leaf parsley
1/4 teaspoon (1.5 g) fine salt, for the dressing
1/8 teaspoon (0.3 g) black pepper, for the dressing

Instructions

Heat the oven and prepare the vegetables. Set a rack in the center of the oven and heat it to 425°F (220°C). Peel the sweet potatoes if you prefer a softer, more uniform bite; leaving the skins on is fine after scrubbing them well. Cut them into similarly sized cubes so they roast at the same rate. Slice the red onion and set it aside for the salad rather than roasting it.
Start the farro. Put the rinsed pearled farro, water, and 1/2 teaspoon salt in a medium saucepan. Bring the water to a boil, then lower the heat so it simmers steadily. Cook uncovered for about 20 to 25 minutes, or until the grains are tender but still pleasantly chewy. Pearled farro cooks more quickly than semi-pearled or whole farro, so check the package directions if yours gives a different time. Drain any water that remains, then return the farro to the warm pan.
Roast the sweet potatoes. While the farro cooks, toss the cubes with 1 1/2 tablespoons olive oil, cumin, and 1/4 teaspoon black pepper. Spread them in one layer on a rimmed baking sheet, leaving a little space between pieces. Roast for 25 to 30 minutes, turning them once about halfway through, until browned at the edges and easily pierced with a fork. Crowding the pan can make them steam instead of brown; use two pans if needed.
Make the lemon-herb dressing. In a small bowl or jar, whisk or shake together the extra-virgin olive oil, lemon juice, maple syrup, Dijon mustard, garlic, parsley, 1/4 teaspoon salt, and 1/8 teaspoon pepper. Taste a small amount and adjust with a little more lemon for sharpness or maple syrup for sweetness. The dressing should taste slightly more assertive on its own than you want it to taste once it coats the grains and vegetables.
Toast the pepitas. Put the pepitas in a dry skillet over medium heat and stir for about 3 to 5 minutes, until they smell nutty and begin to pop. Transfer them to a plate so the residual heat in the pan does not darken them further. This step can happen while the sweet potatoes finish roasting; keep an eye on the seeds, since they can go from toasted to scorched quickly.
Assemble and serve. Pour about two-thirds of the dressing over the warm, drained farro and stir to coat. Add the roasted sweet potatoes, sliced red onion, arugula, cranberries, and feta, then fold gently so the potatoes hold their shape. Add more dressing as needed. Finish with the toasted pepitas and a few grinds of black pepper. Serve warm or at room temperature; if you prefer crisp greens, fold in the arugula just before serving.

Tips

Check which farro you have. This recipe is timed for pearled farro, which has had its outer bran removed and usually cooks in about 20 to 25 minutes. Semi-pearled or whole farro takes longer and may need extra water, so follow the package timing and taste for tenderness rather than relying only on the clock. Drain excess water when it is done; the grains should be chewy, not mushy.
Give the vegetables room. Spread the sweet potatoes in a single layer and turn them once. If the cubes are packed tightly or piled on top of one another, they will soften in their own moisture instead of developing browned edges. Use a second sheet pan if your first one is crowded, and rotate the pans if your oven browns unevenly.
Balance the dressing to your ingredients. Lemons vary in size and tartness, and dried cranberries can be quite sweet. Begin with the listed dressing amounts, then taste it with a grain or potato before changing it. A little extra lemon or salt can brighten a bowl that tastes flat; add maple syrup gradually if your lemon is especially sharp.
Keep the texture you like. For distinct, crisp greens, leave the arugula out until the last moment. If you like a softer, slightly wilted salad, toss it with the warm farro and potatoes. Add the pepitas at the end either way, since they stay crunchiest when they are not sitting in dressing.

Serving Suggestions

This salad works as a substantial lunch or a meatless dinner because the farro and roasted vegetables make it filling, while the greens and lemon dressing keep each bite from feeling heavy. For a composed meal, spoon it onto a platter and scatter the feta, cranberries, and pepitas across the top rather than mixing every topping in. That presentation makes the colorful ingredients easy to see and gives guests a choice of how much cheese or crunch they want.

Serve it alongside a bowl of tomato or lentil soup, grilled vegetables, or a simple green salad if you are building a larger meal. It also fits well on a potluck table: offer it warm or at room temperature, and keep extra dressing nearby for anyone who wants a brighter finish. If it is being served outdoors or sitting out during a meal, follow the usual food-safety timing and refrigerate leftovers within two hours.

Variations

Make it gluten-free: Farro is a type of wheat, so it is not suitable for someone avoiding gluten. Replace it with 1 cup (about 185 g) dry quinoa, rinsed well, and cook it according to its package directions; quinoa has a lighter, fluffier texture and a milder, slightly nutty taste. Brown rice is another option, though it takes longer to cook and gives the salad a firmer, less chewy base.

Swap the greens, cheese, or fruit: Baby spinach or chopped kale can stand in for arugula. Spinach is milder, while kale is sturdier and benefits from being finely sliced. Use goat cheese instead of feta for a softer, tangier finish, or omit the cheese for a dairy-free salad. Chopped dried apricots or raisins can replace the cranberries; both make the overall flavor sweeter, so taste the dressing before adding extra maple syrup.

Change the crunch and seasoning: Toasted walnuts or pecans can replace pepitas in the same amount, bringing a richer, more buttery flavor. For a little heat, add a pinch of red pepper flakes to the dressing. You can also add a teaspoon of grated lemon zest for a more pronounced citrus aroma. Keep any added nuts or seeds separate until serving if you are preparing the salad ahead.

Make it a more substantial main: Add a can of drained and rinsed chickpeas, or serve the salad with cooked lentils. These additions make the bowl heartier and work with the existing cumin and lemon flavors. If adding a moist ingredient, dress the farro first and then taste the assembled salad, since the extra components may need a little more salt, lemon, or dressing.

Storage and Reheating

Refrigerate the salad within two hours of serving in a covered, airtight container. It keeps for 3 to 4 days in the refrigerator. The grains and sweet potatoes hold up well, but the arugula will soften as it sits, and the pepitas will lose some of their crunch. For the best make-ahead texture, store the cooked farro and potatoes together, keep the dressing in a separate jar, and refrigerate the greens, feta, and pepitas separately. Assemble individual portions shortly before eating.

To serve leftovers cold, stir in a spoonful of reserved dressing or a small squeeze of lemon if the grains seem dry. For a warm portion, heat it in a covered microwave-safe dish, stirring once, or warm it gently in a skillet with a splash of water. USDA FSIS guidance is to reheat leftovers to 165°F (74°C); check the center with a food thermometer if you are reheating a full portion. Add fresh arugula and pepitas after warming. Freezing is not recommended for the assembled salad because the greens and feta change texture, though plain cooked farro can be frozen separately.

Frequently Asked Questions

Can I make sweet potato farro salad ahead?

Yes. Cook the farro and roast the sweet potatoes up to 3 days ahead, then refrigerate them in a covered container. The dressing can also be made ahead and kept chilled; stir or shake it before using because the oil and lemon juice may separate. For the freshest result, combine the components shortly before serving and add the arugula, feta, and pepitas at the end.

Can I serve this salad cold?

Yes. It is good warm, at room temperature, or cold. For a cold salad, let the freshly cooked farro and roasted potatoes stop steaming before combining them with the greens, so the arugula does not wilt immediately. If chilled ingredients taste muted, bring a serving out for a few minutes and refresh it with a little lemon juice or dressing before eating.

What can I use instead of farro?

Quinoa is a useful gluten-free substitute, while brown rice, barley, or wheat berries can also provide a hearty grain base. Barley and wheat berries contain gluten, just as farro does. Cooking times and water amounts vary by grain, so cook the substitute separately according to its package directions, drain it if necessary, and then use the same dressing and salad components.

Do I need to peel the sweet potatoes?

No. The skins are edible, and leaving them on saves a little preparation time and gives the roasted cubes a more rustic texture. Scrub and dry the potatoes well before cutting. Peel them if you want softer, more even pieces or if the skins are thick or blemished. Whichever way you prepare them, cut the cubes close to the same size so they finish roasting together.

How do I keep the farro from getting mushy?

Use pearled farro and begin checking it near the lower end of the package cooking time. The grains should be tender with a little chew, not split and soft. Drain leftover cooking water as soon as it reaches that point, and avoid leaving the cooked farro sitting in hot water. Tossing it with dressing while warm helps flavor it without requiring a longer simmer.
