This isn’t your average salad—and thank goodness for that. With slow-cooked beets, juicy oranges, crunchy fennel, and fluffy quinoa, this vibrant dish is as satisfying as it is beautiful. It’s a little sweet, a little savory, and a whole lot refreshing—especially on those days when the thought of turning on the oven makes you sweat. Bonus: your slow cooker does most of the heavy lifting.

If you’re anything like me, when summer hits, the last thing you want is a heavy meal—or a hot kitchen. This salad checks all the right boxes: it’s light but filling, easy to prep ahead, and loaded with textures and flavors that play so well together you’ll wonder why you haven’t been slow-cooking your salad ingredients all along. It’s a great way to use fresh beets when they’re abundant and inexpensive, and the mandarin oranges bring that juicy pop of sunshine to every bite. Whether you serve it for lunch, dinner, or your next backyard gathering, this one earns a spot in your summer rotation.

Ingredients for a Colorful, Nutrient-Packed Meal

This isn’t one of those salads that leaves you rummaging through the fridge an hour later. It’s hearty enough to satisfy but still light enough to keep things breezy. Here’s what you’ll need:

Fresh beets: Look for medium-sized ones with firm skins and vibrant greens still attached (if you’re lucky). Beets are a powerhouse of fiber, folate, and color. No fresh beets? Pre-cooked or vacuum-packed beets work in a pinch—just skip the slow cooker step.
Olive oil: This adds richness and helps mellow the tang of the citrus. Extra virgin is great if you have it, but don’t stress—use what’s in your cupboard.
Orange: You’ll use both the zest and juice for the dressing. It brightens everything up with a little natural sweetness and that zingy citrus punch. Any orange will do, though I love a good navel for juicing ease.
Honey: Just a touch to balance the acidity. If you’re vegan, maple syrup or agave will do the trick just fine.
Quinoa: The protein-packed, gluten-free base of the whole operation. White quinoa is mild and fluffy, but tri-color adds a little extra texture and color drama. Rinse it well before cooking to avoid any bitterness.
Canned mandarin oranges: These little guys bring a burst of sweetness and are just plain convenient. If you’ve got fresh mandarins or clementines, feel free to peel and segment your own.
Fennel: Crunchy, slightly sweet, and with just a whisper of licorice. Don’t let that scare you off—it mellows beautifully when dressed. Slice it super thin for the best texture.
Green onion (optional): Adds a light kick and pop of color. If raw onion isn’t your thing, feel free to leave it out or sub in chopped chives for something a little gentler.
Salad greens (optional): A bed of greens adds extra volume if you want to stretch the salad or turn it into a showstopper lunch. Baby spinach, arugula, or spring mix all work beautifully.

How to Prep Beets in a Slow Cooker

If roasting beets feels like too much effort (especially when it’s already hot outside), let your slow cooker do the heavy lifting. It’s hands-off, mess-free, and no oven required.

Here’s how: Give your beets a good rinse and trim off the tops and tails. Then wrap each one in foil like a little veggie gift. Drizzle the group with a tablespoon of olive oil before wrapping to keep them tender and flavorful. Pop them into your slow cooker, cover, and cook on high for 3 to 4 hours. You’ll know they’re done when a fork slips in with no resistance.

Once they’re cool enough to handle, the skins will practically peel themselves—just rub them gently with a paper towel or your hands (wear gloves if you’re worried about magenta palms!). Then slice them into thin wedges and get ready for some serious salad glow-up.

Bringing It All Together: A Salad That Feels Fancy (But Isn’t)

Once your beets are cooked and your quinoa’s nice and fluffy, it’s time to build this colorful bowl of goodness.

Start by making the dressing—zest your orange (you just need a teaspoon), then squeeze out about two tablespoons of juice. Whisk that together with the remaining olive oil, honey, a pinch of salt, and a few grinds of black pepper. It’s bright, sweet, and just tangy enough to make everything sing.

Here’s the fun part: Divide the dressing. Use about a tablespoon to gently coat the beets—this gives them a head start soaking up flavor. Then toss your mandarin oranges and fennel with another splash of dressing. Finally, mix the rest right into the quinoa so every bite gets a little zesty love.

To serve, layer the dressed quinoa in a bowl or platter, pile the beets and orange-fennel mix over the top, and sprinkle with green onions if you’re using them. Want to stretch it or add a leafy base? Serve it all over a bed of salad greens. Fancy enough for a dinner party, easy enough for Tuesday night.

Serving Suggestions and Easy Variations

This salad is a bit of a chameleon—it plays well as a side dish or the main event, depending on what you need it to be. Serve it slightly chilled or at room temp (no one’s mad about skipping reheating in the summer). It’s perfect for backyard cookouts, potlucks, light lunches, or that moment when you realize you haven’t eaten a vegetable in… a while.

Want to bulk it up? Add grilled chicken, chickpeas, or crumbled goat cheese for a protein boost. No fennel? Thinly sliced celery or cucumber gives a similar crunch. Out of mandarin oranges? Fresh orange segments or even sliced strawberries can step in and still keep things sweet and refreshing.

If you’re making this ahead of time, keep the dressing separate until just before serving to keep everything bright and crisp. And don’t be afraid to improvise—this recipe is forgiving and flexible, just like a good summer meal should be.
