Romaine Red Onion & Fennel Salad with Tart Lime Dress

Shredded raw fennel brings a mild anise sweetness that plays off the sharp bite of red onion and the sturdy crunch of romaine in this no-cook side salad.

The surprise here is the cauliflower florets. Left raw, they add a dense, snappy texture that holds up well against the lime dressing without going soggy.

The dressing itself is bold. A full half cup of fresh lime juice with just one tablespoon of olive oil means this leans tart and bright rather than rich. Minced garlic and a touch of paprika round it out without weighing anything down. Toss the dressing in right before serving so the romaine stays crisp.

This works beautifully next to grilled fish or alongside a grain bowl. The fennel and lime combination feels especially right in warm weather when you want something cold and sharp on the plate.

Pro Tips

• Shred the fennel bulb thin, ideally with a mandoline. Thick chunks won’t absorb the dressing well and create an uneven bite.
• Use fresh lime juice only. Bottled lime juice tastes flat and won’t deliver the same punch in a dressing this simple.
• Toss just before serving. The acid in the lime will wilt the romaine quickly if it sits.
• Save the fennel fronds for garnish. They add a pop of green and reinforce the anise flavor.

Variations

• Citrus swap: Use grapefruit juice in place of lime for a slightly sweeter, less acidic dressing.
• Add crunch: Toss in toasted pumpkin seeds or slivered almonds for a nutty contrast.
• Mediterranean twist: Add Kalamata olives and a crumble of feta to push it toward a Greek-style salad.
