How to Make Citrus Spinach Salad with Grapefruit, Orange & Toasted Walnuts

Toast the walnuts

Preheat a dry skillet over medium heat. Add 1 cup walnut halves and cook 4–5 minutes, tossing frequently, until fragrant and lightly browned. Transfer to a plate; let cool completely. Rough-chop just before serving to preserve texture.

Prep the citrus

Slice off the top and bottom of 2 grapefruits and 2 oranges. Stand fruit flat; cut away peel and pith. Holding the fruit over a bowl, slip a paring knife along each membrane to release supremes. Squeeze remaining membranes into the bowl to catch extra juice for the dressing.

Whisk the vinaigrette

Measure 3 Tbsp reserved citrus juice, 1 Tbsp honey, 1 tsp Dijon, and a pinch of sea salt in a small bowl. Whisk until salt dissolves. Drizzle in 3 Tbsp olive oil until creamy and emulsified. Stir in ½ tsp lime zest and a crack of black pepper. Taste and adjust sweetness or acidity as needed.

Rinse & dry greens

Soak 8 cups baby spinach in a large bowl of icy water for 2 minutes to crisp. Lift into a salad spinner; spin until completely dry. Waterlogged leaves dilute dressing and turn slimy.

Assemble the salad

In a wide serving bowl, layer half the spinach, half the citrus segments, and half the walnuts. Repeat. Drizzle with about ¾ of the dressing; toss gently just to coat. Add more dressing if desired.

Finish & serve

Crumble ¼ cup feta over top. Scatter reserved walnuts for presentation. Serve immediately on chilled plates for the crispest texture.

Expert Tips

Keep it cold

Chill your serving bowl and plates in the freezer 10 minutes before assembling; the temperature contrast keeps spinach perky and walnuts snappy.

Juice最大化

Microwave citrus 10 seconds before cutting; warm essential oils release more juice and aroma.

Batch-toast

Toast a double batch of walnuts and freeze in a zip bag; you'll have salad-ready crunch for months.

Color pop

Use a mix of pink and white grapefruit for a painterly look; blood oranges in winter add dramatic ruby wheels.

Dress sparingly

Under-dress rather than over-dress; you can always add more, but soggy spinach can't be undone.

Revive limp greens

Soak sad spinach in ice water with ½ tsp baking soda for 5 minutes; rinse and spin dry to restore crunch.

Variations to Try

Mediterranean: Swap feta for crumbled goat cheese, add ¼ cup pitted Kalamata olives and a handful of torn mint.
Protein boost: Top with warm farro, grilled shrimp, or shredded rotisserie chicken for a complete meal.
Low-FODMAP: Replace honey with maple syrup and omit feta; use orange zest only to keep fructose low.
Spicy kick: Whisk ¼ tsp chipotle purée into dressing and scatter pickled red onions on top.
Stone-fruit summer: Trade citrus for sliced peaches and nectarines; add fresh basil and grilled halloumi.
Kid-friendly: Use mandarin segments, candied walnuts, and a poppy-seed yogurt dressing for sweeter notes.
