When January’s grey skies have you day-dreaming of sunshine, this salad is the edible equivalent of opening every blind in the house. I first threw it together for a last-minute brunch with neighbors, and by the time the bowls were empty three people had already asked for the recipe. The secret is letting the orange segments bathe in a whisper of extra-virgin olive oil while you whisk the lemon dressing—10 minutes of patience that concentrates the citrus perfume and turns humble baby spinach into something downright luxurious. Whether you serve it alongside grilled salmon at a summer dinner party or pack it for a bright desk lunch, it tastes like someone bottled California and tucked it between salad leaves.

Why This Recipe Works

Triple Citrus Hit: Orange segments, lemon zest and juice layer brightness without puckering tartness.
Quick Infusion: A 10-minute citrus rest adds restaurant-level depth in the time it takes to set the table.
Texture Balance: Creamy avocado, snappy toasted almonds, and juicy orange keep every forkful interesting.
Make-Ahead Magic: Dressing keeps 5 days; spinach stays perky when stored with a paper towel in the box.
One-Bowl Wonder: Minimal dishes, maximum color—perfect for busy weeknights or pot-luck brunches.
Nutrient Dense: Nearly 100 % of your daily vitamin C, plus iron from spinach aided by citrus for better absorption.

Ingredients You'll Need

Quality matters when a recipe has so few components. Look for spinach sold in breathable clamshells—leaves should be perky, not damp or squeaky. Seek out oranges that feel heavy for their size; thin-skinned varieties like Cara Cara or blood orange perfume the bowl beautifully. Your olive oil should be fresh-grassy enough that you’d happily dip bread into it solo.

How to Make Citrus-Infused Spinach Salad with Oranges & Lemon Dressing

Prep the Citrus

Slice off the top and bottom of each orange. Following the curve of the fruit, cut away peel and pith. Over a medium bowl, slip a paring knife along each membrane to release supremes. Squeeze remaining membranes to capture extra juice. You should have about 1 cup segments plus 2 Tbsp juice.

Quick Infusion

Drizzle 1 tsp olive oil and a pinch of flaky salt over orange segments. Gently fold; let stand 10 minutes while you continue. This brief maceration draws out fragrant oils and softens the citrus so it glazes the greens later.

Tame the Onion

Very thinly slice ¼ small red onion into half-moons. Submerge in ice water for 5 minutes to remove sharpness, then blot dry. You’ll get that pop of color and crunch minus the lingering bite.

Build the Lemon Dressing

In a jam jar combine zest of 1 lemon, 3 Tbsp fresh juice, 1 tsp Dijon, 1 tsp maple syrup, ½ tsp salt, and ¼ tsp black pepper. Let sit 2 minutes so zest hydrates. Add 5 Tbsp olive oil, seal jar, and shake vigorously until emulsified and glossy.

Toast the Almonds

Place ⅓ cup almonds in a dry skillet over medium heat. Stir frequently until fragrant and lightly browned, 3–4 minutes. Transfer to a plate to cool; they’ll crisp as they cool and add welcome crunch to the soft greens.

Assemble the Greens

In a large serving bowl, combine 6 packed cups baby spinach, drained onion, and half of the oranges. Drizzle with ¾ of the dressing; toss gently just to coat. Over-handling bruises spinach, so aim for a light touch.

Top & Finish

Add remaining oranges, 1 diced avocado, toasted almonds, and ¼ cup crumbled feta. Drizzle remaining dressing if desired, finish with a grind of black pepper, and serve immediately for peak color contrast.

Expert Tips

Use a Microplane

Zesting with a rasp grater prevents bitter pith and releases more aromatic oils than a box grater.

Dry Spinach Thoroughly

Water on leaves dilutes dressing and can make the salad soggy. A salad spinner is worth the drawer space.

Add Protein

Grilled shrimp, rotisserie chicken, or white beans turn this side into a satisfying entrée.

Serve Chilled Plates

Ten minutes in the fridge keeps greens crisp on a hot patio—especially welcome at summer gatherings.

Make It Vegan

Skip the feta and add 2 Tbsp nutritional yeast for umami or use candied pecans for sweet-salty crunch.

Double the Dressing

It keeps a week and is marvelous drizzled over roasted asparagus or grain bowls later.

Variations to Try

Storage Tips

Dressing: Refrigerate in an airtight jar up to 5 days. If it separates, shake to re-emulsify.

Components: Keep greens, oranges, and add-ins in separate containers; assemble just before eating. Prepped ingredients last 3 days.

Leftover Salad: Already dressed salad wilts within hours. If you must store it, place a paper towel on top, seal tightly, and eat within 24 hours.

Frequently Asked Questions

Absolutely—just give it a quick rinse and spin to refresh leaves that may have been compressed in transit.
