Winter Citrus & Spinach Salad with Avocado & Lemon Vinaigrette
When January’s grey skies feel endless, this jewel-toned salad is my edible ray of sunshine. I developed the recipe five winters ago after a particularly brutal cold snap in Chicago—farmers-market spinach was the only green that looked perky, and the citrus bins at Whole Foods were bursting with blushing cara-cara oranges, sunset-hued blood oranges, and knobby-skinned Meyer lemons. One forkful of those bright segments against buttery avocado and earthy baby spinach and I was, quite literally, tasting color again.
Since then, the salad has become my go-to for everything from brunch showers to hurried Tuesday lunches. It takes 15 minutes start-to-finish, pairs beautifully with roast salmon or crusty sourdough, and—thanks to a sturdy spinach base—won’t wilt if you need to dress it an hour ahead. Friends joke that it’s “winter’s answer to the caprese”: equally photogenic, seasonally smart, and guaranteed to disappear first at any potluck.
Why This Recipe Works
- Triple-citrus punch: Using two fresh segments plus a zippy lemon vinaigrette layers bright flavor without cloying sweetness.
- Avocado insurance: A quick toss in the dressing prevents browning so you can prep ahead stress-free.
- Texture playground: Creamy avocado, juicy citrus, crunchy toasted almonds, and tender spinach keep every bite interesting.
- 5-minute vinaigrette: One jar, no whisk, no garlic to mince—just shake and you’re done.
- Make-ahead friendly: Components keep 3 days separately; dressed salad holds 1 hour without wilting.
- Vitamin-C boost: One serving delivers 120 % daily value—perfect for cold-and-flu season.
Ingredients You'll Need
Great produce is non-negotiable here. Look for spinach with perky, small leaves—baby spinach is milder and needs zero stem removal. If you can only find mature bunches, trim the woody stems and give the leaves a 30-second ice-water bath to crisp them back up.
When choosing citrus, pick fruit that feels heavy for its size; thin-skinned cara-cara and blood oranges are easiest to segment. If you spot Meyer lemons, grab them—their floral, less-acidic juice is dreamy in the vinaigrette. Regular Eureka lemons work, but add a teaspoon of honey to balance the sharper bite.
For the avocado, buy Hass that yield slightly at the stem end but aren’t mushy. A tiny bit of firmness helps the cubes hold their shape when you fold them into the greens. Toasted sliced almonds add crunch; sub toasted pumpkin seeds for a nut-free version. Finally, a good extra-virgin olive oil with grassy notes ties everything together—reach for something in the mid-price range; you’ll taste the difference.
How to Make Winter Citrus & Spinach Salad with Avocado & Lemon Vinaigrette
Make the quick-pickle red onions
Thinly slice ¼ small red onion and place in a jar with 2 Tbsp lemon juice, 1 Tbsp warm water, and a pinch of salt. Shake and set aside while you prep everything else—this softens the bite and turns them a gorgeous fuchsia.
Toast the almonds
Place ⅓ cup sliced almonds in a dry skillet over medium heat. Stir constantly for 3–4 min until golden and fragrant. Slide onto a plate to cool; hot nuts will steam and soften if left in the pan.
Segment the citrus
Slice off both ends of 2 cara-cara and 1 blood orange. Stand fruit on a cut side and follow the curve of the fruit to remove peel and pith. Over a bowl, cut between membranes to release jewel-like segments; squeeze remaining membranes to extract extra juice for the dressing.
Shake the lemon vinaigrette
In a small jar combine 3 Tbsp fresh lemon juice, 1 tsp Dijon, 1 tsp honey, ½ tsp kosher salt, and ¼ cup olive oil. Seal and shake vigorously until creamy and emulsified. Taste—add more honey if your citrus is tart, more salt if it tastes flat.
Cube the avocado
Halve 1 ripe avocado, remove pit, and score flesh while still in skin. Scoop out cubes with a spoon into a small bowl; drizzle with 1 tsp of the dressing and gently toss. This creates a micro-coat of acidulated oil that prevents browning.
Assemble the greens
In a wide, shallow bowl layer 6 loosely packed cups baby spinach. Scatter citrus segments, pickled onions (drained), and avocado cubes on top. This keeps the spinach from bruising when you toss later.
Dress and finish
Drizzle ¾ of the vinaigrette over the salad. Using your hands or tongs, gently lift and fold until leaves are glossy but not soggy. Taste a leaf—add remaining dressing if needed. Sprinkle toasted almonds and serve immediately.
Expert Tips
Serve chilled plates
Pop your serving plates in the freezer for 5 min. A frigid surface keeps spinach perky and avocado cool on a warm kitchen counter.
Dry, dry, dry
Water clinging to spinach will thin your dressing. Use a salad spinner, then blot with a kitchen towel for insurance.
Cut citrus last
Citrus segments weep juice as they sit. Segment right before assembly so every jewel stays plump.
Double the dressing
The vinaigrette keeps 1 week refrigerated. Make a double batch for grain bowls or roasted vegetables later in the week.
Variations to Try
- Mediterranean twist: Swap almonds for toasted pine nuts and add ¼ cup crumbled feta plus a handful of torn mint.
- Protein powerhouse: Top with warm farro and a jammy seven-minute egg for a filling grain bowl.
- Winter fruit medley: Supplement citrus with thinly sliced ripe pear or pomegranate arils when blood oranges disappear.
- Spicy kick: Whisk ¼ tsp Aleppo pepper or a dash of cayenne into the dressing for subtle heat that amplifies sweetness.
Storage Tips
Components: Keep spinach, citrus segments, pickled onions, avocado, almonds, and dressing in separate containers. Spinach stays crisp for 4 days in a produce box lined with paper towel. Citrus keeps 3 days refrigerated; pat segments dry and store in an airtight jar with a splash of juice to prevent drying. Avocado cubes submerged in the vinaigrette stay green for 24 hours. Almonds stay crunchy 1 week at room temp in a jar with a tight lid.
Dressed salad: Best within 1 hour. If you must store leftovers, transfer to a container with a slightly damp paper towel on top, seal, and refrigerate up to 8 hours. Expect slight avocado browning; give it a gentle toss and a squeeze of lemon before serving.
