Ingredients for beet and red onion salad

Roasted beets meet sharp red onions and jewel-like pomegranate in this vibrant, restaurant-worthy salad.

The beets are the star here—organic beets from the grocery store's fresh produce section work best, but any medium-sized variety will do. Look for deep ruby-colored ones; the darker, the sweeter. I always grab mine from Whole Foods or the farmers' market when in season (spring through fall), but the regular supermarket beets are fine year-round. Pro tip: leave the skins on for roasting—they add texture and nutrients. For the red onion, yellow or white varieties both work well, but avoid the sweet onion if you want that classic sharp bite. Thinly slice it about 1/8-inch thick for perfect texture.

No pomegranate seeds? Dried cranberries at half the amount add a similar tart pop, though they won't have that juicy burst. Fresh thyme hard to find? Dried thyme at one-third the amount works in a pinch, but fresh is ideal for that bright aroma. The dressing can be made ahead—store it in a jar for up to 1 week. Want extra crunch? Toasted pecans or candied walnuts are fantastic swaps for the walnuts. For the balsamic vinegar, aged balsamic glaze from Trader Joe's adds instant restaurant flair—just use half the amount since it's already sweetened.

Roasted beets keep beautifully in the fridge for 5 days if stored in an airtight container with a paper towel to absorb moisture. The dressing stays fresh for 1 week in the fridge, but I usually make just enough for immediate use since it's so quick. For meal prep, assemble the salad the morning of—beets soften over time, and you want that perfect creamy texture. The pomegranate seeds? Buy them pre-seeded from Trader Joe's to save time, or crack your own with a hammer and towel (it's messy but worth it). This salad reheats beautifully if you want to serve it warm—just toss with a little extra olive oil before heating.

Step-by-step instructions for earthy sweetness with pomegranate pop

Here's how to transform humble beets into a showstopping salad that balances earthy depth with vibrant pop.

Preheat your oven to 400°F and line a baking sheet with parchment paper. Wrap each of the 2 whole medium beets tightly in aluminum foil, leaving room for expansion. Place them on the baking sheet and roast for 45-50 minutes until completely tender—you'll know they're done when a knife slides in easily with no resistance.

Real talk: Don't skip the foil. It keeps the beets from drying out and makes peeling them later a breeze. Once roasted, let them cool for 10 minutes before handling. The skins will peel right off under running water, revealing that gorgeous deep pink interior we're after.

While the beets cool, peel and cut them into ¼-inch thick slices. Thinly slice the 1 whole red onion (about ⅛-inch thick) and place both in separate bowls. For the pomegranate seeds, I like to crack mine fresh over a bowl to catch any stray arils that might fall.

Chop the 0.25 cup fresh thyme leaves into tiny pieces—this releases their aromatic oils. Toast the 0.5 cup walnuts in a dry skillet over medium heat for 3-4 minutes until fragrant and golden. Watch them closely—they burn fast! Let all ingredients cool completely before assembling.

In a small bowl, whisk together the 0.25 cup extra-virgin olive oil, 2 tbsp balsamic vinegar, 1 tbsp lemon juice, 1 tbsp maple syrup, and 1 tsp Dijon mustard. Season with 1 tsp salt and 0.5 tsp black pepper. Taste and adjust—you want a balance of sweet, tangy, and savory that makes your mouth water.

Here's the thing—this dressing needs to sit for 5 minutes before using. The flavors meld beautifully during this time, creating that perfect harmony of earthy, sweet, and bright. If it looks too thick, add 1 tsp water to loosen it slightly.

In a large bowl, combine the sliced beets and red onion. Drizzle with half of the dressing and toss gently to coat. Add the 0.5 cup pomegranate seeds and 0.5 cup toasted walnuts, then fold in the chopped thyme. The pomegranate will burst with each bite, while the walnuts add satisfying crunch.

This is where the magic happens: the contrast between tender beets, crisp onion, juicy pomegranate, and crunchy walnuts creates an experience that's both visually stunning and delicious. Taste as you go—you might want to add more dressing or adjust seasoning before serving.

Let the salad sit for 10 minutes before serving. This resting period allows all the flavors to truly meld together. The beets will absorb some of the dressing, and the pomegranate seeds will soften just enough to release their juices.

Garnish with additional thyme leaves and a drizzle of extra dressing if desired. Serve immediately while the beets are still warm from the roasting process—this enhances their natural sweetness. Pair with grilled chicken or crusty bread for a complete meal that's as beautiful as it is delicious.

Storing and reheating your leftovers

Fridge Storage Tips

Store your roasted beets and sliced red onions separately in airtight containers for up to 5 days. The beets will soften further but stay delicious—just toss them with a little extra dressing when serving.

Keep the pomegranate seeds and toasted walnuts in a separate container to maintain their crispness. I like using glass containers from Pyrex because they're sturdy and let me see the vibrant colors. 💫

Freezing for Later

This salad doesn’t freeze well due to the pomegranate seeds and walnuts, but you can freeze the roasted beets and dressing separately for up to 3 months.

Store the beets in a single layer on a tray, then transfer to a freezer bag with parchment between slices to prevent sticking. Thaw overnight in the fridge before using. The dressing freezes beautifully—just give it a good stir after thawing to re-emulsify.

Reheating Warm Beets

If you want to serve this salad warm, gently reheat the roasted beets in a skillet with 1 tablespoon olive oil over low heat for 3-4 minutes. Add a splash of water to keep them moist.

Toss with fresh dressing and pomegranate seeds just before serving—the contrast of warm beets with cool, juicy pomegranate is amazing. Perfect for chilly evenings! 🔥

Dressing Refresh

The dressing keeps for 1 week in the fridge, but if it separates, simply whisk it vigorously to recombine. For extra freshness, add a squeeze of lemon juice or a pinch of salt before serving.

I often make a double batch—one for immediate use and one to store for quick salads later in the week. The flavors actually improve as the spices meld together over time.

Onion Texture Trick

If your red onions lose their crispness after storing, revive them by soaking in ice water for 5 minutes before adding to the salad. This restores their crunch and sharp flavor. For maximum freshness, slice the onions just before assembling the salad—this ensures they stay crisp and vibrant.

Thinly sliced onions are key to that perfect balance of sharpness and sweetness in every bite. 🧅

Make-Ahead Assembly

Assemble the salad the morning of serving for the best texture and flavor. Store all components separately in the fridge, then combine just before eating. This keeps the beets from getting soggy and the pomegranate seeds from losing their juicy pop.

If you're short on time, prep everything the night before and store in resealable containers—just toss, dress, and serve in the morning. It’s that easy! ✨
