Ingredients for sweet potato and beetroot salad

Roasted sweet potatoes and beetroots meet crisp greens and toasted pecans in this vibrant, restaurant-worthy salad.

The sweet potatoes and beetroots are the stars here, so pick firm, vibrant produce—no soft spots or bruises. I always grab organic sweet potatoes from Trader Joe's when I can, as they tend to be sweeter. Beetroots should be deep red, not pale. Peeled and cubed uniformly ensures even roasting. For the arugula, baby leaves give the best texture without overpowering the roasted vegetables. If you're using regular arugula, tear the leaves rather than chopping them to keep them tender.

No pecans? Walnuts or almonds work beautifully—just toast them first. Short on orange juice? Lemon juice with a touch of maple syrup gets you close, though the orange adds a unique depth. The maple syrup can be swapped for agave nectar if you prefer. For the vinegar, apple cider gives the best flavor, but white wine vinegar or balsamic are solid alternatives. Fresh thyme is ideal, but dried thyme at one-third the amount works in a pinch. The lemon zest can be omitted if you're short, but it really elevates the dish.

Roasted vegetables keep well for 4-5 days in the fridge, so make a big batch. Store the dressing separately and toss everything together right before serving. The pecans stay fresh for up to 2 weeks in an airtight container at room temperature. This salad reheats beautifully—perfect for meal prep. Portion into containers with the dressing on the side to keep everything crisp.

Step-by-step instructions for sweet potato and beetroot salad

Roast until tender, then toss with vibrant citrus and aromatic thyme for a salad that balances earthy sweetness with bright acidity.

Preheat your oven to 400°F and line two rimmed baking sheets with parchment paper. Toss the 1.5 lb sweet potatoes and 1 lb beetroots (both cubed) with 2 tablespoons of the extra-virgin olive oil, 1 teaspoon of the salt, and ¼ teaspoon of the black pepper. Spread them in a single layer—don't crowd the pan, or they'll steam instead of roast.

Roast for 25-30 minutes, stirring once halfway through, until the edges are deep golden brown and a knife slides in easily. The sweet potatoes should be tender with caramelized edges, while the beetroots will soften slightly but retain their shape. Here's the thing—if they look underdone, cover with foil and roast another 10 minutes. Overcooking turns them mushy, and we want that perfect balance of texture.

While the vegetables roast, pulse the 0.5 cup pecans in a food processor until they're coarsely chopped (not powdered). Transfer them to a dry skillet over medium heat and toast for 3-4 minutes, stirring constantly, until they're golden brown and fragrant. Remove from heat immediately—they'll continue cooking from residual heat, and you want them just crisp.

In the same skillet (no need to clean it—the browned bits add flavor), add the thinly sliced red onion and cook over medium heat for 5-6 minutes until softened and just beginning to brown at the edges. Here's where the salad starts building flavor—those caramelized bits will brighten the entire dish. Remove from heat and set aside with the pecans.

In a medium bowl, whisk together the 0.25 cup orange juice, 2 tablespoons apple cider vinegar, 1 tablespoon maple syrup, 1 tablespoon chopped fresh thyme leaves, and 1 teaspoon lemon zest. Gradually whisk in the remaining 0.3 cup extra-virgin olive oil until emulsified. Taste and adjust seasoning with the remaining 0.5 teaspoon salt and ¼ teaspoon black pepper—this dressing should be tangy-sweet with a bright citrus finish.

I like to let the dressing sit for 5 minutes before using it. This allows the thyme to infuse the oil and the flavors to meld. The dressing should coat the back of a spoon without being too thick—if it separates, whisk again before using.

Let the roasted sweet potatoes and beetroots cool slightly (they'll be hot), then transfer them to a large serving bowl. Add the toasted pecans and caramelized red onion, then gently fold in the 5 oz fresh arugula. Pour the dressing over the vegetables and toss everything together with your hands or a large spoon—you want to coat the greens evenly without bruising them.

Here's the moment that matters: taste before serving. The salad should have a perfect balance of sweetness from the roasted vegetables, crunch from the pecans, sharpness from the red onion, and brightness from the citrus dressing. If it needs more acidity, add another ½ tablespoon apple cider vinegar. If it needs more sweetness, add another ½ teaspoon maple syrup. Real talk: the dressing is the soul of this salad, so don't skimp on flavor adjustments.

Cover the salad and let it rest for 10-15 minutes before serving. This allows the flavors to meld and the dressing to fully coat the vegetables. The sweet potatoes and beetroots will continue to release their natural sweetness, while the arugula softens slightly but maintains its peppery bite.

Serve immediately while the vegetables are still warm from roasting. The contrast of warm, caramelized roots with cool, peppery arugula and crisp pecans makes this salad truly special. Store any leftovers in an airtight container in the refrigerator for up to 3 days, but the flavors are best enjoyed fresh.

Essential equipment for this dish

Roasting Pan Essentials

Start with two rimmed baking sheets—they're the workhorses of roasting. I swear by All-Clad stainless steel half-sheets because they distribute heat evenly and handle high temperatures without warping.

For budget-friendly options, Ozeri roasting pans work great and are dishwasher-safe. Line them with parchment paper to prevent sticking and make cleanup a breeze. 🔥

Precision Tools for Cubing

A sharp chef's knife and cutting board are non-negotiable for uniform cubes. I use a Wüsthof 8-inch chef's knife—its razor-sharp edge ensures clean cuts that roast evenly. For speed, a mandoline slicer (like the Benriner) gives you perfect ½-inch cubes in seconds.

Just be careful with those fingers! A peeler also helps remove beetroot skins efficiently.

Skillet for Toasting

Your 10-inch cast iron skillet (like a Lodge pre-seasoned skillet) is perfect for toasting pecans and caramelizing onions. The heavy base maintains even heat, preventing burnt pecans. If you don’t have cast iron, a stainless steel skillet works too—just avoid nonstick, as those browned bits add critical flavor.

A wooden spoon helps stir without scratching the pan.

Dressing Whisk & Bowl

For the dressing, a balloon whisk (like the OXO Good Grips) emulsifies oil and citrus perfectly. Use a medium glass bowl—glass doesn’t retain flavors from previous uses, unlike plastic.

I like to whisk in a small whisking bowl first to test seasoning before transferring to the main bowl. A measuring spoon set ensures precise vinegar and syrup ratios.

Serving Essentials

Serve the salad in a large ceramic bowl (like Le Creuset) to keep everything warm and showcase its vibrant colors. For individual portions, glass salad bowls (such as Pyrex) work well.

A tongs set helps toss ingredients gently without crushing the arugula. For garnish, keep fresh thyme sprigs and lemon wedges on hand to add brightness at the table.

Storage Containers

Store leftovers in glass airtight containers (like Glasslock) to maintain freshness. Divide the dressing and greens separately if prepping ahead—this keeps the arugula crisp. For meal prep, mason jars (like Kerr) let you layer ingredients: dressing at the bottom, greens next, and roasted veggies on top.

Label with dates to track freshness—this salad stays best for 3-4 days in the fridge. ✨
