Healthy Citrus Spinach Salad with Oranges, Lemons & Winter Greens

Bright, zesty, and packed with immune-boosting vitamins, this winter salad is my go-to when the days grow short and the produce aisle starts to feel monotonous. I first threw it together on a blustery January afternoon when the farmer’s market was down to little more than spinach, a crate of navel oranges, and a few scraggly bunches of kale. One bite of the finished bowl—peppery greens kissed with sunny citrus, creamy avocado, and the crunch of toasted pumpkin seeds—and I was hooked. Now it’s the dish I bring to every January potluck, the one I pack in mason jars for a week of desk lunches, and the salad that convinces even salad-skeptics that winter eating can still feel vibrant. If you need a burst of sunshine on your plate (and in your body), this is the recipe to bookmark.

Ingredients You'll Need

Great salads start with great produce. Because this recipe is raw, every ingredient has to pull its weight. Here’s what to look for:

Baby spinach

Choose organic if possible—tender leaves mean fewer pesticides and zero sandy grit. Check the “best by” date; older spinach exudes moisture and will wilt faster once dressed.

Navel oranges

Feel heavy for their size and smell fragrant at the stem end. Thin-skinned varieties (Cara Cara or blood orange) peel easier and segment into tidy “supremes.”

Lemon

One organic lemon pulls double duty: zest for the dressing and juice to keep avocado bright. If you can find Meyer lemons, their floral sweetness means you can scale back on maple syrup.

Winter greens mix

I like a 50/50 blend of baby kale and shaved Brussels sprouts. Buy them pre-shredded to save time, or massage chopped kale with a pinch of salt for 30 seconds to soften.

Avocado

Look for a stem button that flick off easily and reveals green underneath. If you’re prepping ahead, buy them under-ripe and let them sit next to bananas for 24 hours.

Pumpkin seeds (pepitas)

Raw, not roasted. Toasting them yourself in a dry skillet for 90 seconds intensifies nuttiness without added oil.

Extra-virgin olive oil

A grassy, peppery oil marries beautifully with citrus. Choose one in a dark bottle; polyphenols degrade under light.

Pure maple syrup

Grade A amber offers delicate sweetness that won’t overpower tart lemon. In a pinch, use agave or honey (if not vegan).

Dijon mustard

Acts as an emulsifier so dressing stays creamy. Whole-grain mustard adds pops of texture, but smooth Dijon keeps the salad kid-friendly.

Shallot

Mellower than red onion, it practically dissolves into the dressing. Soak minced shallot in lemon juice for 5 minutes to tame any heat.

How to Make Healthy Citrus Spinach Salad with Oranges, Lemons & Winter Greens

Toast the seeds

Place a medium skillet over medium heat. Add ¼ cup raw pumpkin seeds and shake the pan every 20 seconds until they puff and pop, about 90 seconds total. Slide onto a small plate to cool; residual heat can burn them.

Make the lemon-maple vinaigrette

In a jam jar, combine zest of 1 lemon, 3 Tbsp fresh lemon juice, 2 tsp Dijon, 1 Tbsp maple syrup, ½ tsp sea salt, and ¼ tsp black pepper. Let minced shallot (1 Tbsp) bathe in the acid for 5 minutes to mellow, then add ¼ cup extra-virgin olive oil. Screw the lid on tight and shake until creamy and pale yellow. Taste and adjust sweet-tart balance; winter citrus varies wildly.

Segment the oranges

Slice the top and bottom off 2 navel oranges so they sit flat. Following the curve of the fruit, cut away peel and white pith. Hold the orange over the salad bowl and slip a paring knife along each membrane to release perfect supremes. Squeeze the membranes to extract any leftover juice—waste not, want not.

Prep the greens

Rinse 4 cups baby spinach and 2 cups baby kale under cold water. Spin dry in a salad spinner—excess water dilutes dressing. If the kale leaves feel tough, stack, roll, and chiffonade into thin ribbons, then massage with a pinch of salt for 30 seconds until darker and silkier.

Assemble in layers

In a wide salad bowl, spread greens as a fluffy base. Scatter orange segments, ½ thinly sliced small avocado, and ¼ cup shaved fennel (optional but delightful). Finish with cooled toasted pumpkin seeds and a light shower of flaky sea salt for crunch.

Dress and toss

Drizzle 3 Tbsp dressing around the edges of the bowl, not on top—this prevents the avocado from browning. Using clean hands, gently lift and fold until every leaf glistens. Add more dressing by the teaspoon; overdressed salads sag fast.

Serve immediately

Divide onto chilled plates. Garnish with citrus zest curls and an extra crack of pepper. Pair with crusty whole-grain bread or a cup of hot lentil soup for a complete winter lunch.

Expert Tips

Chill your plates

Ten minutes in the freezer prevents wilting and keeps avocado firm while you leisurely dine.

Dry = crisp

Even a tablespoon of clinging water dilutes acid and kills that bright flavor. Spin like you mean it.

Build a barrier

Layer avocado in the middle of the jar if meal-prepping; the acid from oranges above and dressing below prevents browning.

Double the dressing

It keeps 5 days refrigerated and is fantastic on roasted beets, grilled chicken, or even a rice bowl.

Zest first, juice second

Microplane the lemon before halving; it’s far easier to zest a whole fruit than wobbly squeezed hemispheres.

Add edible petals

A scattering of calendula or pansy petals turns an everyday salad into dinner-party material in seconds.

Variations to Try

Protein boost

Top with a scoop of warm quinoa or a jammy seven-minute egg for an extra 6 g protein.
Nutty crunch

Swap pumpkin seeds for toasted pistachios or candied pecans if you want sweet-salty vibes.
Citrus swap

Use ruby grapefruit or mandarins when oranges are out of season—just adjust maple to taste.
Cheese please

Crumbled goat cheese or shaved Parmesan add tangy richness; vegan? Try a sprinkle of almond “parm.”
Grain bowl twist

Serve the salad over warm farro or wild rice to morph it into hearty dinner fare.

Storage Tips

Immediate leftovers: Store undressed salad in an airtight container lined with a paper towel. Refrigerate up to 24 hours; add avocado and dressing just before serving.

Dressing: The lemon-maple vinaigrette keeps 5 days refrigerated in a sealed jar. Olive oil may solidify; let sit at room temp 10 minutes and shake vigorously.

Meal-prep jars (48-hour): Layer from bottom up—dressing, orange segments, pumpkin seeds, kale/spinach mix, avocado (brush with lemon), spinach barrier. Invert onto a plate or shake into a bowl at lunchtime.

Avocado halves: Keep the pit in, brush flesh with lemon juice, press plastic wrap directly onto surface, and refrigerate up to 24 hours. Some browning may occur but flavor stays fresh.

Frequently Asked Questions

Absolutely. Pumpkin seeds are already tree-nut free. If you sub almonds or walnuts, simply swap back to seeds or use toasted sunflower kernels for the same crunch without allergens.

Cut top and bottom off to expose flesh. Stand fruit upright and follow the curve to remove peel plus pith. Slip knife along membranes, releasing segments into a bowl. Afterward, squeeze remaining membrane “cores” over a separate cup for juice—perfect for the dressing or sparkling water.

With around 18 g net carbs per serving (mostly from oranges), it’s on the higher side for strict keto. You can halve the fruit and sub in more avocado and pumpkin seeds to drop carbs to ~10 g.

Oil-based vinaigrettes solidify and can break when thawed. Instead, refrigerate for up to 5 days or make a half batch if you don’t think you’ll use it all.

Grilled salmon, roasted chickpeas, or thinly sliced seared tofu all echo the citrus notes. Avoid heavy red meats that can overpower the delicate sweet-tart balance.

Oxidation happens when cut surfaces contact air. Brush with lemon juice, press plastic wrap directly against flesh, and refrigerate. Even if lightly browned, the flavor is fine—just less photogenic.
