Notes
Expert Recipe Tips:Dry the lettuce extremely well for maximum crunch. Excess moisture dilutes the dressing and softens the romaine. After rinsing, spin thoroughly, then pat with paper towels if needed. Super-dry lettuce makes the biggest difference in keeping this salad crisp.Chill the oranges before assembling. Cold mandarin segments help keep the salad refreshing and prevent the dressing from warming the greens, especially when serving at potlucks or outdoor gatherings.Use a microplane for the garlic. Finely grating the garlic (instead of mincing) helps it blend completely into the dressing, giving you a smoother, more balanced flavor without sharp chunks.Balance sweetness to taste. Canned mandarin oranges vary in sweetness. After whisking the dressing, taste and adjust with a splash of vinegar for more brightness or a drizzle of honey for extra sweetness.Add the cucumbers at the last minute. Cucumbers release water quickly, so adding them right before mixing helps prevent the salad from becoming watery if prepping ahead.Toast the sunflower seeds for deeper flavor. Even raw, unsalted sunflower seeds become more nutty and aromatic with a quick 2–3 minute toast in a dry pan. Let cool before adding to preserve crunch.Cut everything into bite-sized pieces. Chopping the romaine into smaller pieces helps the oranges, seeds, and croutons distribute evenly so every bite gets the perfect balance of textures.Layer the salad if transporting. For potlucks, build in this order and toss at the event: Cucumbers + onions on bottom, oranges, lettuce, seeds + croutons on top. Add dressing right before serving. This prevents sogginess and keeps textures perfect.Double the dressing if adding protein. If you turn this into a meal by adding chicken or shrimp, you’ll likely need about 25–30% more dressing since the protein absorbs some of it.Serve immediately after tossing. The acid in the dressing softens greens quickly, so for the crispest salad, toss no more than 5–10 minutes before serving.
