The first week of January always feels like stepping off a roller-coaster of cookies, champagne, and second helpings. My jeans protest, my skin feels dull, and my energy is somewhere under the pile of wrapping paper still clinging to the living-room corners. Last year, instead of signing up for an expensive juice cleanse, I started a gentler ritual: this Detox Citrus & Spinach Salad with Lemon Vinaigrette. After three days of enjoying it for lunch, my afternoon headaches vanished, my sweet-tooth cravings quieted, and—most importantly—I felt excited about vegetables again.
What makes this salad magic is the balance: bright citrus wakes up your palate, baby spinach replenishes iron and folate, creamy avocado gives satiating healthy fats, and the zippy lemon vinaigrette ties everything together without a speck of refined sugar. It’s the edible equivalent of a deep breath. Bring it to a New-Year brunch and watch even the devout carnivores reach for seconds. Pack it in mason jars for a week of desk lunches that won’t wilt by noon. Or serve it alongside simply grilled salmon when you want something that feels luxurious yet is secretly rehab for your liver.
Below you’ll find my longest, most detailed version yet—because if we’re going to reset, let’s do it deliciously, methodically, and with plenty of make-ahead tricks so the healthy choice becomes the easy choice.

Ingredients You'll Need
Quality ingredients matter when you’re showcasing raw produce. Here’s what to look for—and how to swap if your grocery cart comes up short.
Baby Spinach
Choose organic if possible (spinach is on the EWG “Dirty Dozen”). The leaves should be perky, not slimy, with no yellow edges. Baby leaves are more tender and require zero stemming. If you only have mature spinach, remove the thick ribs and chiffonade larger leaves so they integrate easily. No spinach? Try baby kale, arugula, or a spring mix—just steer clear of heavier greens like mature curly kale unless you massage it first.
Citrus Trio
I use 1 large navel orange for sweetness, 1 ruby grapefruit for gentle bitterness, and 1 small lime for acidic punch. When buying, pick fruit that feels heavy for its size—this signals juiciness. Thin-skinned oranges are easier to supreme; avoid thick, puffy navels that hide more pith than flesh. If grapefruit is too bitter for your crowd, swap in blood oranges or tangerines. In summer, peak peaches or nectarines make a stone-fruit twist.
Avocado
Hass avocados give the creamiest texture. Test ripeness by gently pressing the stem end—it should yield slightly without feeling mushy. Buy green ones a day or two ahead and ripen next to bananas in a paper bag. To keep cut halves from browning, brush with vinaigrette and press plastic wrap directly onto the surface.
Pumpkin Seeds (Pepitas)
They add magnesium, zinc, and a delightful crunch. Buy raw and toast at home for 6 minutes in a dry skillet; season with a pinch of sea salt. Swap with sunflower seeds if nut-free, or slivered almonds if nuts are okay. Toasting is non-negotiable—it unlocks nutty flavor that plain seeds just don’t have.
Fresh Herbs
Parsley or mint lifts the salad from “healthy” to “restaurant worthy.” Choose flat-leaf (Italian) parsley; curly is tougher. Mint should smell bright and sweet. Rinse herbs in icy water, spin dry, and store wrapped in damp paper towel inside a zip-top bag—lasts up to 10 days.
Extra-Virgin Olive Oil
Since the dressing is raw, pick a buttery, mild oil, not a peppery Tuscan finishing oil that will overpower citrus. Look for harvest date within 18 months; store in a cool cupboard, never next to the stove.
Dijon Mustard
Acts as an emulsifier so the vinaigrette stays creamy for hours. Use smooth, not whole-grain, unless you like visible seeds. Maille or Edmond Fallot are my favorites; they contain wine for extra tang.
How to Make Detox Citrus & Spinach Salad with Lemon Vinaigrette
Prep the Citrus
Slice off both ends of the orange and grapefruit to expose the flesh. Stand fruit upright and follow the curve of the body with a sharp chef’s knife to remove peel and white pith in wide strips. Hold the peeled fruit over a bowl and use a paring knife to cut between membranes, releasing supremes. Squeeze remaining membrane into the bowl to harvest extra juice—you’ll use it in the vinaigrette. Repeat with grapefruit and lime (lime supremes are tiny but pack zing). Reserve 2 Tbsp of the pooled juice for dressing.
Toast the Seeds
Place a dry skillet over medium heat. Add ¼ cup raw pepitas; shake pan every 30 seconds. After 4–6 minutes they will puff slightly and turn golden with a few pops. Tip onto a plate to stop cooking. Season with a pinch of flaky salt while warm.
Blend the Lemon Vinaigrette
In a small jar combine 2 Tbsp reserved citrus juice, 2 Tbsp fresh lemon juice, 1 tsp Dijon, ¼ tsp sea salt, and ⅛ tsp black pepper. Let sit 1 minute so salt dissolves. Add 6 Tbsp extra-virgin olive oil. Screw lid and shake vigorously 10 seconds until thick and glossy. (Alternatively whisk in a bowl.) Taste: it should be bright with balanced acidity. Add a pinch of salt or a few extra drops of lemon if it tastes flat—citrus sweetness varies daily.
Prep Avocado Last-Minute
Halve avocado, remove pit, and cube flesh inside the shell: score lengthwise and crosswise without piercing skin. Use a spoon to scoop out neat cubes. Immediately drizzle with 1 tsp vinaigrette to prevent oxidation.
Assemble the Greens
In a wide salad bowl place 6 packed cups baby spinach. Add ½ cup loosely packed parsley leaves and ¼ cup mint leaves. Toss gently to distribute herbs.
Layer & Dress
Scatter citrus supremes and avocado cubes over greens. Sprinkle with toasted pepitas. Drizzle 3 Tbsp of vinaigrette evenly. Using clean hands or salad servers, fold gently to coat—over-mixing bruises spinach. Taste a leaf and add more dressing only if needed (usually another teaspoon or two).
Season Finish
Top with flaky sea salt and a few cracks of fresh black pepper. Serve immediately on chilled plates for restaurant-level perkiness.
Optional Glow-Up
For extra protein add a 7-minute jammy egg or a scoop of chilled quinoa. For crunch diversity toss in a handful of roasted chickpeas just before serving so they stay crisp.
Expert Tips
Chill Your Plates
Ten minutes in the freezer prevents wilting on contact and keeps avocado firm—crucial for summer gatherings.
Dry Spinach Thoroughly
Water clinging to leaves dilutes dressing. Use a salad spinner, then blot with paper towel. Your vinaigrette will cling, not slide.
Dress Just Before Serving
Acid in citrus breaks down cell walls; 30 minutes ahead is fine, but overnight equals soggy spinach.
Double the Dressing
It keeps 5 days refrigerated and doubles as a marinade for chicken or a drizzle over roasted sweet potatoes.
Supreme Over a Bowl
Catch every drop of juice for the dressing; a rimmed plate wastes liquid gold.
Use a Ceramic Knife
Prevents avocado browning longer than steel blades—handy when prepping for a crowd.
Variations to Try
-
Green Goddess Boost: Blend 2 Tbsp fresh tarragon and 1 Tbsp chives into the vinaigrette for a creamy-herby vibe without adding dairy.
-
Winter Waldorf: Swap citrus for diced apple and pear; add celery and toasted walnuts. The lemon vinaigrette still works beautifully.
-
Mediterranean Detox: Replace pepitas with ¼ cup crumbled feta (omit salt in dressing) and add ½ cup cooked chickpeas for protein.
-
Spicy Sunshine: Whisk ¼ tsp cayenne or ½ tsp harissa paste into dressing; finish with thin jalapeño rings for heat seekers.
-
Grain Bowl Remix: Serve salad over warm farro or brown rice; the vinaigrette mingles with starches for a saucy finish.
Storage Tips
The biggest enemy here is moisture. Store each component separately in glass containers:
- Washed Greens: Line a snap-lock container with a paper towel, add spinach, top with another towel. Keeps 5 days crisp.
- Citrus Supremes: Submerge in their own juice in a small jar; cover and refrigerate 4 days.
- Avocado: Best cut day-of, but if you must, brush with vinaigrette, pack in airtight box with pit to reduce oxygen exposure; use within 24 hours.
- Dressing: Refrigerate up to 5 days; bring to room temp and shake vigorously before using (olive oil solidifies cold).
- Toasted Seeds: Cool completely, then jar with a silica-gel packet (saved from seaweed packages) to keep them crunchy for weeks.
