Ingredients You'll Need

This salad celebrates winter's citrus bounty, so let's talk about each component and how to choose the best produce. The star players are navel oranges—look for ones that feel heavy for their size with smooth, firm skin. Avoid any with soft spots or wrinkled skin, as these indicate age or improper storage. When possible, opt for organic since you'll be using some of the zest in the dressing.

Baby spinach forms the leafy base of our salad. I prefer pre-washed organic baby spinach for convenience, but if you're buying bunches, look for crisp leaves with no yellowing or slimy spots. Store spinach in a container lined with paper towels to absorb excess moisture, which extends its life by several days.

For the almonds, sliced varieties toast more evenly than whole nuts, but feel free to use whatever you have on hand. Toasting might seem like an extra step, but it transforms the nuts from ordinary to extraordinary, bringing out their natural oils and adding a deeper, more complex flavor that complements the bright citrus perfectly.

The lemon juice and zest in the dressing should come from fresh lemons—never bottled juice. Fresh lemons provide a bright, clean acidity that bottled versions simply can't match. When zesting, only remove the yellow outer layer; the white pith underneath is bitter and will ruin your dressing.

How to Make Healthy Orange and Lemon Citrus Salad with Spinach for January

Toast the Almonds

Preheat your oven to 350°F (175°C). Spread sliced almonds in a single layer on a baking sheet and toast for 5-7 minutes, stirring once halfway through. Keep a close eye on them—they can go from golden to burnt quickly. You're looking for a light golden color and a fragrant, nutty aroma. Cool completely before using.

Prepare the Citrus

Using a sharp knife, slice off both ends of the oranges. Stand each orange on one cut end and slice downward following the curve of the fruit, removing all peel and white pith. Hold the peeled orange in your hand over a bowl and carefully slice between the membranes to release perfect segments. Squeeze any remaining juice from the membranes into a separate small bowl for the dressing.

Make the Lemon Vinaigrette

In a small jar with a tight-fitting lid, combine 3 tablespoons fresh lemon juice, 1 teaspoon lemon zest, ½ teaspoon Dijon mustard, 1 tablespoon honey, and a pinch of salt and pepper. Let this sit for 2 minutes so the salt dissolves. Add 3 tablespoons olive oil, screw on the lid, and shake vigorously until emulsified. Taste and adjust seasoning—it should be bright and tangy but balanced.

Prep the Spinach

If using pre-washed baby spinach, simply place it in a large salad bowl. For bunches, wash thoroughly in cold water, spin dry, and remove any tough stems. The key is ensuring the leaves are completely dry so the dressing adheres properly. If time allows, chill the spinach for 15 minutes before assembling—it makes the salad extra crisp and refreshing.

Assemble the Salad

Add the orange segments and half the toasted almonds to the spinach. Drizzle with about two-thirds of the dressing. Using clean hands or salad tongs, gently toss from bottom to top, being careful not to break the orange segments. Add more dressing if needed, but start conservatively—you can always add more, but you can't take it away.

Add Final Touches

Transfer the salad to a serving platter or individual bowls. Scatter the remaining toasted almonds on top for crunch. If using avocado, slice it just before serving and arrange on top. The avocado adds a creamy richness that pairs beautifully with the bright citrus. Serve immediately for the best texture and flavor.

Expert Tips

Segment Like a Pro

Use a very sharp, thin-bladed knife for segmenting citrus. A dull knife will tear the membranes and make the segments look ragged. Practice makes perfect here—your first few might not be beautiful, but they'll still taste amazing.

Dress Just Before Serving

The acid in the dressing will start to break down the spinach within 30 minutes. If you're preparing ahead, keep the components separate and dress just before serving for maximum crispness.

Room Temperature Citrus

Remove citrus from the refrigerator 30 minutes before preparing. Room temperature oranges and lemons yield more juice, making them easier to segment and enhancing their natural sweetness.

Toast Nuts in Batches

Toast a whole bag of almonds at once and store them in an airtight container. They'll stay fresh for up to a month, making future salads even quicker to prepare.

Variations to Try

Mediterranean Twist

Add crumbled feta cheese, sliced Kalamata olives, and a sprinkle of dried oregano. Swap almonds for toasted pine nuts and add a drizzle of good olive oil just before serving.

Protein Power

Top with grilled shrimp or shredded rotisserie chicken for a complete meal. The citrus pairs beautifully with seafood, while chicken adds satisfying protein.

Winter Jewel

Use blood oranges and ruby grapefruit for stunning color variation. Add pomegranate arils and use pistachios instead of almonds for a truly spectacular presentation.

Superfood Boost

Add a handful of cooked quinoa, hemp seeds, and a sprinkle of goji berries. This transforms the salad into a nutrient-dense meal that will keep you energized for hours.

Green Goddess

Mix in some arugula or baby kale for a peppery kick. Add thinly sliced fennel bulb for crunch and a tablespoon of chopped fresh mint for brightness.

Asian Fusion

Replace almonds with toasted sesame seeds, add sliced jicama, and make a dressing with rice vinegar, sesame oil, and a touch of soy sauce. Garnish with crispy wonton strips.

Storage Tips

Make-Ahead Components

The beauty of this salad lies in its components that can be prepped separately. Toast the almonds up to 5 days ahead and store in an airtight container at room temperature. Segment the oranges up to 24 hours ahead and store in their own juice in the refrigerator. The dressing can be made up to 3 days ahead—just shake well before using as it will separate.

However, keep the spinach unwashed and undressed until just before serving. Once dressed, the salad is best enjoyed immediately as the acid begins to break down the greens. If you must prep ahead, store components separately and combine just before serving.

Leftover Storage

Leftover dressed salad will keep for up to 24 hours in the refrigerator, though the spinach will wilt somewhat. Store in an airtight container with a paper towel on top to absorb excess moisture. The citrus segments may release additional juice, creating a delicious marinade that actually enhances the flavor.

For best results, store any undressed portions separately. The citrus segments will keep for 3 days in their juice, while the dressing lasts for up to a week refrigerated. Always give the dressing a good shake before using as the oil and acid will separate.

Frequently Asked Questions

A: Absolutely! Valencia oranges work beautifully and are actually juicier than navels. Blood oranges create a stunning presentation with their ruby flesh, while mandarins or clementines are perfect for a sweeter, more delicate flavor. Just adjust the amount of honey in the dressing based on your citrus choice—sweeter fruits need less added sugar.

A: Try baby kale or arugula for a peppery twist, or use a mix of butter lettuce and romaine for a milder flavor. Even shredded green cabbage works well and adds great crunch. If you're introducing greens to picky eaters, start with half spinach and half romaine, gradually increasing the spinach ratio over time.

A: Yes! Replace the almonds with roasted pumpkin seeds, sunflower seeds, or even crispy chickpeas for crunch. You could also add diced jicama or water chestnuts for texture without nuts. The salad is delicious even without any crunch element—the citrus really is the star here.

A: Transform this into a complete meal by adding protein! Grilled shrimp, seared scallops, or blackened salmon are all fantastic. For vegetarian options, add chickpeas, white beans, or quinoa. A soft-boiled egg on top creates a lovely richness that pairs well with the citrus.

A: Emulsification happens when oil is slowly incorporated into acid while whisking vigorously. Try this method: whisk the lemon juice, mustard, and honey together first, then drizzle in the oil while whisking constantly. Or use a jar and shake for 30 seconds. Adding a teaspoon of Dijon mustard helps stabilize the emulsion.

A: This salad is perfect for potlucks! Pack everything separately: spinach in a large bowl with a paper towel on top, citrus segments in a jar with their juice, dressing in a small container, and almonds in a zip-top bag. Assemble just before serving. It travels well and always impresses guests with its vibrant colors.
